ABOUT WESTLAKE CHEMICAL CORPORATION

We are a vertically integrated global manufacturer and marketer of basic chemicals, vinyls, polymers and building products. Our products include some of the most widely used chemicals in the world, which are fundamental to many diverse consumer and industrial markets, including flexible and rigid packaging, automotive products, coatings, residential and commercial construction as well as other durable and non-durable goods. We operate in two principal operating segments, Olefins and Vinyls. We are highly integrated along our olefins product chain with significant downstream integration into polyethylene and styrene monomer. We are also an integrated global producer of vinyls with substantial downstream integration into polyvinyl chloride (“PVC”) building products.

We began operations in 1986 after our first polyethylene plant, an Olefins segment business, near Lake Charles, Louisiana was acquired from Occidental Petroleum Corporation. We began our vinyls operations in 1990 with the acquisition of a vinyl chloride monomer (“VCM”) plant in Calvert City, Kentucky from the Goodrich Corporation. In 1992, we commenced our Vinyls segment building products operations after acquiring three PVC pipe plants. Since 1986, we have grown rapidly into an integrated global producer of petrochemicals, vinyls, polymers and building products. We achieved this by acquiring existing plants or constructing new plants and completing numerous capacity or production line expansions. We regularly consider acquisitions and other internal and external growth opportunities that would be consistent with or complementary to our overall business strategy.

In 2014, we formed Westlake Chemical Partners LP (“Westlake Partners”) to operate, acquire and develop facilities for the processing of natural gas liquids and related assets. Also in 2014, Westlake Partners completed an initial public offering of 12,937,500 common units (the “Westlake Partners IPO”). As of June 30, 2016, Westlake Partners’ assets consist of a 13.3% limited partner interest in Westlake Chemical OpCo LP (“OpCo”), as well as the general partner interest in OpCo. Prior to the Westlake Partners IPO, OpCo’s assets were wholly owned by us. OpCo’s assets include two natural gas liquids processing facilities at our Lake Charles site, one natural gas liquids processing facility at our Calvert City site and a 200-mile common carrier ethylene pipeline that runs from Mont Belvieu, Texas to the Longview, Texas site, which includes our Longview polyethylene production facility. We retain an 86.7% limited partner interest in OpCo, a 52.2% limited partner interest in Westlake Partners (common and subordinated units), a general partner interest in Westlake Partners and incentive distribution rights. The operations of Westlake Partners are consolidated in our financial statements. We are party to certain agreements with Westlake Partners and OpCo whereby, among other things, OpCo sells us 95% of the ethylene it produces on a cost-plus basis that is expected to generate a fixed margin per pound of $0.10. We use this ethylene in the production processes of both our Olefins and Vinyls segments.

On August 31, 2016, we completed our previously announced acquisition of Axiall Corporation, a Delaware corporation (“Axiall”). Pursuant to the terms of the previously announced Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 10, 2016, by and among us, Axiall and Lagoon Merger Sub, Inc., a Delaware corporation that is a wholly-owned subsidiary of us (“Merger Sub”), Merger Sub merged with and into Axiall (the “Merger”), with Axiall surviving the Merger as a wholly-owned subsidiary of Westlake.

We benefit from highly integrated production facilities that allow us to process raw materials into higher value-added chemicals and building products. As of February 17, 2016, we (directly and through OpCo and our 95% owned Asian joint venture) had 19.7 billion pounds per year of aggregate production capacity at 21 manufacturing sites in North America, Europe and Asia.

We are a Delaware corporation with our principal executive offices located at 2801 Post Oak Boulevard, Suite 600, Houston, Texas 77056. Our telephone number at such address is (713) 960-9111.

POTENTIAL SUBSIDIARY GUARANTORS

One or more of our direct or indirect wholly-owned subsidiaries may fully and unconditionally guarantee any series of debt securities offered by this prospectus in the future. We may file one or more post-effective amendments to our registration statement to add such potential subsidiary guarantors. The applicable prospectus supplement will name the subsidiary guarantors, if any, for that series of debt securities and will describe the terms of the guarantee by the subsidiary guarantors.

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risk factors and all of the other information included in, or incorporated by reference into, this prospectus, including those in Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2016, in evaluating an investment in our securities. If any of these risks were to occur, our business, financial condition or results of operations could be adversely affected. In that case, the trading price of our common stock or preferred stock or value of our debt securities could decline and you could lose all or part of your investment. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

Risks Related to our Principal Stockholder

We will be controlled by our principal stockholder, TTWF LP, and its affiliates as long as they own a majority of our common stock, and our other stockholders will be unable to affect the outcome of stockholder voting during that time. Our interests may conflict with those of the principal stockholder and its affiliates, and we may not be able to resolve these conflicts on terms possible in arms-length transactions.

As long as TTWF LP, which as of September 1, 2016, owns approximately 71.4% of our common stock (the “principal stockholder” or the “selling stockholder”) and its affiliates (the “principal stockholder affiliates”) own a majority of our outstanding common stock, they will be able to exert significant control over us, and our other stockholders, by themselves, will not be able to affect the outcome of any stockholder vote. As a result, the principal stockholder, subject to any fiduciary duty owed to our minority stockholders under Delaware law, will be able to control all matters affecting us (some of which may present conflicts of interest), including:

• the composition of our board of directors and, through the board, any determination with respect to our business direction and policies, including the appointment and removal of officers and the determination of compensation;

• any determinations with respect to mergers or other business combinations or the acquisition or disposition of assets;

• our financing decisions, capital raising activities and the payment of dividends; and

• amendments to our amended and restated certificate of incorporation or amended and restated bylaws.

The principal stockholder will be permitted to transfer a controlling interest in us without being required to offer our other stockholders the ability to participate or realize a premium for their shares of common stock. A sale of a controlling interest to a third party may adversely affect the market price of our common stock and our business and results of operations because the change in control may result in a change of management decisions and business policy. Because we have elected not to be subject to Section 203 of the General Corporation Law of the State of Delaware, the principal stockholder may find it easier to sell its controlling interest to a third party than if we had not so elected. See “Description of Capital Stock—Delaware Business Combination Statute” for a description of Section 203 and the potential positive and negative consequences, depending on the circumstances, of electing not to be subject to it.

In addition to any conflicts of interest that arise in the foregoing areas, our interests may conflict with those of the principal stockholder affiliates in a number of other areas, including:

• business opportunities that may be presented to the principal stockholder affiliates and to our officers and directors associated with the principal stockholder affiliates, and competition between the principal stockholder affiliates and us within the same lines of business;

• the solicitation and hiring of employees from each other; and

4

• agreements with the principal stockholder affiliates relating to corporate services that may be material to our business.

We may not be able to resolve any potential conflicts with the principal stockholder affiliates, and even if we do, the resolution may be less favorable than if we were dealing with an unaffiliated party, particularly if the conflicts are resolved while we are controlled by the principal stockholder affiliates. Our amended and restated certificate of incorporation provides that the principal stockholder affiliates have no duty to refrain from engaging in activities or lines of business similar to ours and that the principal stockholder affiliates will not be liable to us or our stockholders for failing to present specified corporate opportunities to us. See “Description of Capital Stock—Transactions and Corporate Opportunities.”

Risks Related to the Common Stock

Substantial sales of our common stock by the principal stockholder or us could cause our stock price to decline and issuances by us may dilute our stockholders’ ownership interest in our company.

We are unable to predict whether significant amounts of our common stock will be sold by the principal stockholder. Any sales of substantial amounts of our common stock in the public market by the principal stockholder or us, or the perception that these sales might occur, could lower the market price of our common stock. Further, if we issue additional equity securities to raise additional capital, our stockholders’ ownership interest in our company may be diluted and the value of their investment may be reduced.

The price of our common stock may be volatile.

The market price of our common stock could be subject to significant fluctuations. Among the factors that could affect our stock price are:

• our operating and financial performance and prospects;

• quarterly variations in the rate of growth of our financial indicators, such as earnings per share, net income and revenues;

• changes in revenue or earnings estimates or publication of research reports by analysts;

• speculation in the press or investment community;

• strategic actions by us or our competitors, such as acquisitions or restructurings;

• sales of our common stock by stockholders;

• actions by institutional investors or by the principal stockholder;

• fluctuations in oil and gas prices;

• general market conditions, including fluctuations in feedstock, energy and commodity prices; and

• U.S. and international economic, legal and regulatory factors unrelated to our performance.

The stock markets in general have experienced extreme volatility in recent years that has at times been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock and, as a result, an investment in our common stock.

If we are unable to pay regular dividends on our common stock, our stockholders may not receive funds without selling their common stock.

Shortly following our initial public offering in 2004, we paid our initial regular quarterly dividend of at least $0.02125 per share. We have paid regular quarterly dividends since our initial dividend. On August 18, 2016, our

5

board of directors declared a dividend of $0.1906 per share payable on September 20, 2016 to our stockholders of record as of the close of business on September 2, 2016. Any payment of future dividends will be at the discretion of our board of directors and will depend on, among other things, our earnings, financial condition, capital requirements, level of indebtedness, statutory and contractual restrictions applying to the payment of dividends, and other considerations that our board of directors deems relevant. The agreements governing our 6 ¹⁄₂% senior notes due 2029, 6 ³⁄₄% senior notes due 2032, each of our series of 6 ¹⁄₂% senior notes due 2035, 3.600% senior notes due 2026, 5.000% senior notes due 2046 and our Credit Agreement (as defined herein) also include limitations on our payment of dividends. Accordingly, our stockholders may have to sell some or all of their common stock in order to generate cash flow from their investment. Our stockholders may not receive a gain on their investment when they sell their common stock and they may lose the entire amount of the investment.

Provisions in our charter documents or Delaware law may inhibit a takeover, which could adversely affect the value of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws, as well as Delaware corporate law, contain provisions that could delay or prevent a change of control or changes in our management that a stockholder might consider favorable. These provisions apply even if the offer may be considered beneficial by some of our stockholders. If a change of control or change in management is delayed or prevented, the market price of our common stock could decline. Please read “Description of Capital Stock” for a description of these provisions.

Risks Related to the Debt Securities

Our holding company structure may affect our ability to make payments on our debt securities. Holders of our debt securities may be structurally subordinated to the creditors of our subsidiaries.

We currently conduct our operations through subsidiaries, and our operating income and cash flow are generated by our subsidiaries. As a result, cash we obtain from our subsidiaries is the principal source of funds necessary to meet our debt service obligations. Contractual provisions or laws, as well as our subsidiaries’ financial condition and operating requirements, may limit our ability to obtain cash from our subsidiaries that we require to pay our debt service obligations, including payments on the debt securities. In addition, holders of the debt securities will have a junior position to the claims of creditors, including trade creditors and tort claimants, of our subsidiaries to the extent that such subsidiaries do not guarantee such debt securities. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, holders of that subsidiary’s indebtedness and its trade creditors will generally be entitled to payment of their claims from the assets of the subsidiary before any assets are made available for distribution to us.

A holder’s right to receive payments on the debt securities is effectively subordinated to the rights of our existing and future secured creditors. Further, the guarantees of the senior debt securities by the subsidiary guarantors, if any, are effectively subordinated to the guarantors’ existing and future secured indebtedness.

Holders of our secured indebtedness and the secured indebtedness of the subsidiary guarantors, if any, will have claims that are prior to the claims of holders of the senior debt securities to the extent of the value of the assets securing that other indebtedness. In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding-up, liquidation, reorganization or other bankruptcy proceeding, holders of secured indebtedness will have prior claim to our assets that constitute their collateral. Holders of the senior debt securities will participate ratably with all holders of our senior unsecured indebtedness, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. We may apply proceeds of certain asset sales to reduce our secured indebtedness or other secured obligations, but such application will not permanently reduce our ability to incur secured indebtedness and other

6

secured obligations under the indenture in the future. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the senior debt securities. As a result, holders of the senior debt securities may receive less, ratably, than holders of secured indebtedness.

A holder’s right to receive payments on the debt securities could be adversely affected if any of our non-guarantor subsidiaries declares bankruptcy, liquidates or reorganizes.

Some but not all of our subsidiaries may guarantee the debt securities. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, holders of that subsidiary’s indebtedness and its trade creditors will generally be entitled to payment of their claims from the assets of the subsidiary before any assets are made available for distribution to us.

Federal and state statutes allow courts, under specific circumstances, to void guarantees and require holders of the debt securities to return payments received from guarantors.

Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee could be voided or claims in respect of a guarantee could be subordinated to all other debts of the applicable guarantor if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee, received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee and either:

• was insolvent or rendered insolvent by reason of such incurrence;

• was engaged or about to engage in a business or transaction for which the guarantor’s remaining assets constituted unreasonably small capital; or

• intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

In addition, any payment by that guarantor pursuant to its guarantee could be voided and required to be returned to the guarantor or to a fund for the benefit of the creditors of the guarantor.

The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, a guarantor would be considered insolvent if, at the relevant time, the sum of its debts and other liabilities, including contingent liabilities, was greater than the sum of its assets at a fair valuation, and a guarantor that was generally not then paying its debts as they became due would be presumed to be insolvent.

We may incur additional debt ranking equal to the debt securities.

If we incur any additional debt that ranks equally with the debt securities, the holders of that debt will be entitled to share ratably with the holders of the debt securities in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution or other winding-up of our company. This may have the effect of reducing the amount of proceeds paid to a holder of debt securities.

CAUTIONARY STATEMENTS ABOUT FORWARD-LOOKING STATEMENTS

The Private Securities Litigation Reform Act of 1995 provides safe harbor provisions for forward-looking information. Certain of the statements contained in this prospectus are forward-looking statements. All statements, other than statements of historical facts, included in this prospectus that address activities, events or developments that we expect, project, believe or anticipate will or may occur in the future are forward-looking statements. Forward-looking statements can be identified by the use of words such as “believes,” “intends,” “may,” “should,” “could,” “anticipates,” “expected” or comparable terminology, or by discussions of strategies or trends. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot give any assurances that these expectations will prove to be correct. Forward-looking statements relate to matters such as:

• future operating rates, margins, cash flow and demand for our products;

• industry market outlook, including the price of crude oil;

• production capacities;

• currency devaluation;

• our ability to borrow additional funds under our credit facility;

• our ability to meet our liquidity needs;

• our ability to meet debt obligations under our debt instruments;

• our intended quarterly dividends;

• future capacity additions and expansions in the industry;

• timing, funding and results of capital projects, such as the expansion program at our Calvert City facility;

• results of acquisitions, including our acquisition of Axiall, including the benefits, results, effects and timing thereof;

• pension plan obligations, funding requirements and investment policies;

• compliance with present and future environmental regulations and costs associated with environmentally related penalties, capital expenditures, remedial actions and proceedings, including any new laws, regulations or treaties that may come into force to limit or control carbon dioxide and other greenhouse gases emissions or to address other issues of climate change;

• effects of pending legal proceedings; and

• timing of and amount of capital expenditures.

We have based these statements on assumptions and analyses in light of our experience and perception of historical trends, current conditions, expected future developments and other factors we believe were appropriate in the circumstances when the statements were made. Forward-looking statements by their nature involve substantial risks and uncertainties that could significantly impact expected results, and actual future results could differ materially from those described in such statements. Among the factors that could cause actual future results to differ materially are the risks and uncertainties discussed under “Risk Factors” in this prospectus and in our most recent Annual Report on Form 10-K and those described from time to time in our other filings with the SEC, including, but not limited to, the following:

• general economic and business conditions;

• the cyclical nature of the chemical industry;

• the availability, cost and volatility of raw materials and energy;

8

• uncertainties associated with the United States, European and worldwide economies, including those due to the political tensions in the Middle East, the Commonwealth of Independent States (including Ukraine) and elsewhere;

• current and potential governmental regulatory actions in the United States and other countries and political unrest in other countries;

• industry production capacity and operating rates;

• the supply/demand balance for our products;

• competitive products and pricing pressures;

• instability in the credit and financial markets;

• access to capital markets;

• terrorist acts;

• operating interruptions (including leaks, explosions, fires, weather-related incidents, mechanical failure, unscheduled downtime, labor difficulties, transportation interruptions, spills and releases and other environmental risks);

• changes in laws or regulations;

• technological developments;

• our ability to realize anticipated benefits of the acquisition of Axiall and to integrate Axiall’s business;

• charges or other liabilities relating to the acquisition of Axiall;

• the significant indebtedness that we have incurred in connection with the acquisition of Axiall;

• our ability to integrate acquired businesses other than Axiall;

• foreign currency exchange risks;

• our ability to implement our business strategies; and

• creditworthiness of our customers.

Many of these factors are beyond our ability to control or predict. Any of the factors, or a combination of these factors, could materially affect our future results of operations and the ultimate accuracy of the forward-looking statements. These forward-looking statements are not guarantees of our future performance, and our actual results and future developments may differ materially from those projected in the forward-looking statements. 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. Every forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward-looking statement.

USE OF PROCEEDS

Unless we inform you otherwise in the applicable prospectus supplement, we expect to use the net proceeds from the sale of securities for general corporate purposes. These purposes may include:

• repayment or refinancing of debt;

• acquisitions;

• working capital;

• capital expenditures; and

• repurchases and redemptions of securities.

Pending any specific application, we may initially invest funds in short-term marketable securities or apply them to the reduction of short-term indebtedness.

We will not receive any proceeds from the sale of any shares of our common stock that may be sold by the selling stockholder.

RATIO OF EARNINGS TO FIXED CHARGES

We have presented in the table below our historical consolidated ratio of earnings to fixed charges for the periods shown.

Years Ended December 31,

For the Six Months Ended June 30, 2016

Ratio of earnings to fixed charges

14.3x

17.7x

16.1x

9.9x

7.1x

12.3x

We have computed the ratios of earnings to fixed charges by dividing earnings by fixed charges. For this purpose, “earnings” consist of earnings before income taxes plus fixed charges and equity distributions less net capitalized interest and equity investment income. “Fixed charges” consist of interest expense, capitalized interest, amortization of debt issuance costs and that portion of operating lease rental expense (one-third) we have deemed to represent the interest factor of such expense.

No shares of our preferred stock are currently issued or outstanding, therefore no dividends accrued on any shares of our preferred stock for any period presented. Accordingly, the ratio of earnings to combined fixed charges and preferred stock dividends is the same as the ratio of earnings to fixed charges.

DESCRIPTION OF DEBT SECURITIES

The debt securities covered by this prospectus will be our general unsecured obligations. We will issue senior debt securities under an indenture dated as of September 8, 2016, as amended or supplemented from time to time, between us and The Bank of New York Mellon Trust Company, N.A., as trustee.

We have summarized material provisions of the indenture and the debt securities below. This summary is not complete. We have filed the indenture with the SEC as an exhibit to the registration statement, and you should read the indenture for provisions that may be important to you. Please read “Where You Can Find More Information.”

In this summary description of the debt securities, unless we state otherwise or the context clearly indicates otherwise, all references to “we,” “us,” or “our” refer to Westlake Chemical Corporation only and not to any of its subsidiaries.

General

The indenture does not limit the amount of debt securities that may be issued under it, and does not limit the amount of other unsecured debt or securities that we may issue. We may issue debt securities under the indenture from time to time in one or more series. No securities are outstanding under the indenture.

We are not obligated to issue all debt securities of one series at the same time and, unless otherwise provided in the applicable prospectus supplement, we may reopen a series, without the consent of the holders of the debt securities of that series, for the issuance of additional debt securities of that series. Additional debt securities of a particular series will have the same terms and conditions as outstanding debt securities of such series, except for the date of original issuance and the offering price and, if applicable, the initial interest payment date and initial interest accrual date, and will be consolidated with, and form a single series with, such outstanding debt securities.

The senior debt securities will constitute our senior unsecured indebtedness and will rank equally in right of payment with all of our other unsecured and unsubordinated debt and senior in right of payment to all of our subordinated indebtedness. The senior debt securities will be effectively subordinated to, and thus have a junior position to, our secured indebtedness with respect to the assets securing that indebtedness.

We currently conduct our operations through subsidiaries, and our operating income and cash flow are generated by our subsidiaries. As a result, cash we obtain from our subsidiaries is the principal source of funds necessary to meet our debt service obligations. Contractual provisions or laws, as well as our subsidiaries’ financial condition and operating requirements, may limit our ability to obtain cash from our subsidiaries that we require to pay our debt service obligations, including payments on the debt securities. In addition, holders of the debt securities will have a junior position to the claims of creditors, including trade creditors and tort claimants, of our subsidiaries to the extent that such subsidiaries do not guarantee such debt securities.

Neither indenture contains any covenants or other provisions designed to protect holders of the debt securities in the event we participate in a highly leveraged transaction or upon a change of control. The indentures also do not contain provisions that give holders of the debt securities the right to require us to repurchase their securities in the event of a decline in our credit rating for any reason, including as a result of a takeover, recapitalization or similar restructuring or otherwise.

Ranking

In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding-up, liquidation, reorganization or other bankruptcy proceeding, holders of secured indebtedness will have prior claim

11

to our assets that constitute their collateral. Holders of the senior debt securities will participate ratably with all holders of our senior unsecured indebtedness, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. See “Risk Factors—Risks Related to the Debt Securities—A holder’s right to receive payments on the debt securities is effectively subordinated to the rights of our existing and future secured creditors. Further, the guarantees of the senior debt securities by the subsidiary guarantors, if any, are effectively subordinated to the guarantors’ existing and future secured indebtedness.”

The senior debt securities will rank equally with all of our other unsecured and unsubordinated indebtedness and the unsecured and unsubordinated indebtedness of the subsidiary guarantors, if any. As of June 30, 2016, we had an aggregate of $764.9 million of unsecured indebtedness, which includes $250.0 million aggregate principal amount of 3.60% senior notes due 2022, $100.0 million aggregate principal amount of 6 ¹⁄₂% senior notes due 2029, $250.0 million aggregate principal amount of 6 ³⁄₄% senior notes due 2032, $89.0 million aggregate principal amount of 6 ¹⁄₂% senior notes due 2035, $65.0 million aggregate principal amount of 6 ¹⁄₂% senior notes due 2035 and a $10.9 million loan from the proceeds of tax-exempt waste disposal revenue bonds. On August 10, 2016, we issued $750.0 million aggregate principal amount of 3.600% senior notes due 2026 and $700.0 million aggregate principal amount of 5.000% senior notes due 2046. Also on August 10, 2016, an indirect subsidiary of the Company, Westlake International Holdings II C.V., a limited partnership organized under the laws of The Netherlands (the “CV Borrower”), entered into a credit agreement with Bank of America, N.A., as agent and lender, providing the CV Borrower with a $150.0 million term loan facility (the “Dutch Term Loan”). As of the date of this filing, $150.0 million of borrowings are outstanding under the Dutch Term Loan. On August 23, 2016, we entered into a credit agreement (the “Credit Agreement”) by and among Westlake Chemical Corporation, the other borrowers and guarantors referred to therein, the lenders from time to time party thereto, the issuing banks party thereto and JPMorgan Chase Bank, National Association, as Administrative Agent, under which the lenders have committed to provide an unsecured revolving credit facility in an aggregate principal amount of up to $1 billion. The Credit Agreement replaces Westlake’s existing $400 million senior secured third amended and restated credit facility, dated as of July 17, 2014, by and among Westlake, the financial institutions party thereto, as lenders, Bank of America, N.A., as agent, and Westlake Chemical Corporation and certain of its subsidiaries, as borrowers. As of the date of this filing, $450.0 million of borrowings are outstanding under the Credit Agreement. On September 7, 2016, we completed offers to exchange any and all of the $688.0 million aggregate principal amount of the outstanding 4.625% senior notes due 2021 (the “Axiall 2021 Notes”) issued by Eagle Spinco Inc., a wholly-owned subsidiary of Axiall, and of the $450.0 million aggregate principal amount of the outstanding 4.875% senior notes due 2023 (the “Axiall 2023 Notes” and, together with the Axiall 2021 Notes, the “Axiall Notes”) issued by Axiall for new senior notes issued by us having the same maturity and interest rates as the Axiall Notes. In the exchange offers, $624.8 million aggregate principal amount of the 2021 Axiall Notes and $433.8 million aggregate principal amount of the 2023 Axiall Notes were exchanged, respectively, for $624.8 million aggregate principal amount of 4.625% senior notes due 2021 and $433.8 million aggregate principal amount of 4.875% senior notes due 2023 issued by us, leaving outstanding $63.2 million aggregate principal amount of the 2021 Axiall Notes and $16.2 million aggregate principal amount of the 2023 Axiall Notes.

Terms

The prospectus supplement relating to any series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

• the title of the debt securities;

• the total principal amount of the debt securities;

• whether we will issue the debt securities in individual certificates to each holder or in the form of temporary or permanent global securities held by a depositary on behalf of holders;

• the date or dates on which the principal of and any premium on the debt securities will be payable;

12

• any interest rate, the date from which interest will accrue, interest payment dates and record dates for interest payments;

• whether and under what circumstances we will pay any additional amounts with respect to the debt securities;

• whether debt securities are entitled to any guarantee of any subsidiary guarantors and the identity of any such subsidiary guarantors for that series and the terms of such guarantee;

• the place or places where payments on the debt securities will be payable;

• any provisions for optional redemption or early repayment;

• any sinking fund or other provisions that would obligate us to redeem, purchase or repay the debt securities;

• the denominations in which we will issue the debt securities if other than $1,000 and integral multiples of $1,000;

• whether payments on the debt securities will be payable in foreign currency or currency unit or another form and whether payments will be payable by reference to any index or formula;

• the portion of the principal amount of the debt securities that will be payable if the maturity is accelerated, if other than the entire principal amount;

• any additional means of defeasance of the debt securities, any additional conditions or limitations to defeasance of the debt securities or any changes to those conditions or limitations;

• any changes or additions to the events of default or covenants described in this prospectus;

• any restrictions or other provisions relating to the transfer or exchange of the debt securities;

• any terms for the conversion or exchange of the debt securities for other securities; and

• any other terms of the debt securities not inconsistent with the applicable indenture.

We 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 we sell these debt securities, we will describe in the prospectus supplement any material United States federal income tax consequences and other special considerations.

If we sell any of the debt securities 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 applicable prospectus supplement the restrictions, elections, tax consequences, specific terms and other information relating to those debt securities and the foreign currency or currency unit.

Guarantees

One or more of our direct or indirect wholly-owned subsidiaries may fully and unconditionally guarantee any series of debt securities offered by this prospectus in the future. We may file one or more post-effective amendments to our registration statement to add such potential subsidiary guarantors. The applicable prospectus supplement will name the subsidiary guarantors, if any, for that series of debt securities and will describe the terms of the guarantee by the subsidiary guarantors.

Consolidation, Merger and Sales of Assets

The indenture generally permits a consolidation or merger involving us. It also permits us to sell, lease, convey, assign, transfer or otherwise dispose of all or substantially all of our assets. We have agreed, however,

13

that we will not consolidate with or merge into any entity or sell, lease, convey, assign, transfer or dispose of all or substantially all of our assets to any entity unless:

(1) either

• we are the continuing entity; or

• the resulting entity is organized under the laws of the United States, any state thereof or the District of Columbia, and expressly assumes by supplemental indenture the due and punctual payment of the principal of, premium (if any) and interest on and any additional amounts with respect to the debt securities and the performance of our covenants and obligations under the indenture and the debt securities; and

(2) immediately after giving effect to the transaction or series of transactions, no default or event of default under the indenture has occurred and is continuing or would result from the transaction(s).

This covenant will not apply to any merger of another entity into us. Upon any transaction of the type described in and effected in accordance with this section, the resulting entity will succeed to and be substituted for and may exercise all of our rights and powers under the indenture and the debt securities with the same effect as if the resulting entity had been named as us in the indenture. In the case of any asset transfer or disposition other than a lease, when the resulting entity assumes all of our obligations and covenants under the indenture and the debt securities, we 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:

• our failure to pay interest on any debt security of that series for 30 days when due;

• our failure to pay principal of or any premium on any debt security of that series when due;

• our failure to deposit any sinking fund payment relating to any debt security of that series for 30 days when due;

• our failure to comply with any covenant or agreement in that series of debt securities or the indenture (other than an agreement or covenant that has been included in the indenture solely for the benefit of other series of debt securities) for 60 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 indenture that are affected by that failure;

• specified events involving bankruptcy, insolvency or reorganization;

• if applicable, specified events involving the guarantees; and

• any other event of default provided for that series of debt securities.

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 applicable debt securities within 90 days after it occurs. The trustee may withhold notice to the holders of the debt securities of any default or event of default, except in any payment on the debt securities, 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 some cases, 25% in principal amount of all debt securities issued under the indenture that are affected, voting as

14

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 occurs, the principal of and accrued and unpaid interest on all the debt securities of that series 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 default (or, in some cases, of all debt securities issued under the indenture that are affected, voting as one class) may in some cases rescind this accelerated payment requirement and its consequences.

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

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

• the holders of at least 25% in principal amount of the 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 the indenture at the request or direction of any of the holders unless those holders have offered to the trustee indemnity satisfactory to it. Subject to this provision for indemnification, the holders of a majority in principal amount of the outstanding debt securities of a series (or of all debt securities issued under the 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.

The indenture requires us to furnish to the trustee annually a statement as to our performance of certain of our obligations under the indentures and as to any default in performance.

Modification and Waiver

We and the trustee may supplement or amend the indenture with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of all series issued under the 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 whose holders must consent to an amendment, supplement or waiver;

15

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

• reduce the principal of the debt security or change its stated maturity;

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

• change any obligation to pay additional amounts on the debt security;

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

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

• make any change in the percentage of principal amount of debt securities necessary to waive compliance with certain provisions of the indenture or to make any change in the provision related to modification;

• waive a continuing default or event of default regarding any payment on the debt securities;

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

We and the trustee may supplement or amend the indenture or waive any provision of the indenture without the consent of any holders of debt securities issued under the indenture in certain circumstances, including:

• to cure any ambiguity, omission, defect or inconsistency;

• to provide for the assumption of our obligations under the indenture by a successor upon any merger, consolidation or asset transfer permitted under the indenture;

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

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

• to comply with any requirement to effect or maintain the qualification of the indenture under the Trust Indenture Act of 1939, as amended;

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

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

• to supplement any of the provisions of the indenture to the extent necessary to permit or facilitate the defeasance and discharge of any series of debt securities; and

• to provide for the appointment of a successor trustee or to provide for or facilitate the administration of the trusts under the indenture by more than one trustee.

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

16

Defeasance and Discharge

Defeasance. When we use the term defeasance, we mean discharge from some or all of our obligations under an indenture. If we deposit with the trustee under the indenture any combination of money or government securities sufficient to make payments on the debt securities of a series issued under the indenture on the dates those payments are due, then, at our option, either of the following will occur:

• we will be discharged from our obligations with respect to the debt securities of that series (“legal defeasance”); or

• we will no longer have any obligation to comply with specified restrictive covenants with respect to the debt securities of that series, the covenant described under “—Consolidation, Merger and Sales of Assets” and other specified covenants under the indenture, 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 that series will not be entitled to the benefits of the indenture, except for obligations to register the transfer or exchange of debt securities, replace stolen, lost or mutilated debt securities or maintain paying agencies and hold money for payment in trust. In the case of covenant defeasance, our obligation to pay principal, premium and interest on the debt securities, will also survive.

Unless we inform you otherwise in the applicable 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 holders of the debt securities to recognize income, gain or loss for U.S. federal income tax purposes and that the holders would be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the deposit and related defeasance had not occurred. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the United States Internal Revenue Service or a change in law to that effect.

Under current U.S. federal income tax law, legal defeasance would likely be treated as a taxable exchange of debt securities to be defeased for interests in the defeasance trust. As a consequence, a United States holder would recognize gain or loss equal to the difference between the holder’s cost or other tax basis for the debt securities and the value of the holder’s interest in the defeasance trust, and thereafter would be required to include in income a share of the income, gain or loss of the defeasance trust. Under current U.S. federal income tax law, covenant defeasance would not be treated as a taxable exchange of such debt securities.

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 the indenture, subject to exceptions relating to compensation and indemnity of the trustee under the indenture and repayment to us of excess money or government securities, when:

• either

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

(b) 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

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

• we have paid all other sums payable by us with respect to the debt securities of that series.

17

Governing Law

New York law will govern the indentures, the debt securities and the guarantees, if any.

The Trustee

The Bank of New York Mellon Trust Company, N.A. acts as the trustee under the indenture. Unless we inform you otherwise in a prospectus supplement, The Bank of New York Mellon Trust Company, N.A. will act as the trustee with respect to the senior debt securities described in such prospectus supplement.

The indenture contains limitations on the right of the trustee, if it or any of its affiliates is then 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, it must eliminate that conflict or resign within 90 days after ascertaining that it has a conflicting interest and after the occurrence of a default under the indenture, unless the default has been cured, waived or otherwise eliminated within the 90-day period.

Payments and Paying Agents

Unless we inform you otherwise in the applicable prospectus supplement, we will make payments on the debt securities in U.S. dollars at the office of the trustee and any paying agent. At our option, 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 the applicable prospectus supplement, we will make interest payments 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 the applicable prospectus supplement, the trustee under the indenture will be designated as the paying agent for payments on debt securities issued under the indenture. We 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 the applicable prospectus supplement, a “business day” is any day that is not a Saturday, a Sunday or a day on which banking institutions in any of New York, New York, Houston, Texas or a place of payment on the debt securities of that series is authorized or obligated by law, regulation or executive order to remain closed.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will pay to us 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 us, holders entitled to the money must look to us for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

Form, Exchange, Registration and Transfer

We will issue the debt securities in registered form, without interest coupons. 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 designated by us. The security registrar or transfer agent will effect the transfer or exchange if its requirements and the requirements of the applicable indenture are met. We will not charge a service charge for any registration of transfer or exchange of the debt securities. We may, however, require payment of any transfer tax or similar governmental charge payable for that registration.

18

We will appoint the trustee as security registrar for the debt securities. If the applicable prospectus supplement refers to any transfer agents we initially designate, we 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. We may at any time designate additional transfer agents for any series of debt securities.

In the case of any redemption of debt securities of a series or any repurchase of debt securities of a series required under the terms of the series, we will not be required to register the transfer or exchange of:

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

Book-Entry Debt Securities

We may issue the debt securities of a series in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the applicable prospectus supplement. We may issue global debt securities in either temporary or permanent form. We will describe in the applicable prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security.

DESCRIPTION OF CAPITAL STOCK

General

The following descriptions are summaries of material terms of our common stock, preferred stock, amended and restated certificate of incorporation and amended and restated bylaws. Copies of our amended and restated certificate of incorporation and amended and restated bylaws have been incorporated by reference as exhibits to the registration statement of which this prospectus is a part, and you are urged to review these documents. Please read “Where You Can Find More Information.”

As of the date of this prospectus, our authorized capital stock consists of 300 million shares of common stock, par value $0.01 per share, and 50 million shares of preferred stock, par value $0.01 per share.

Common Stock

Each share of common stock entitles the holder to one vote on all matters on which holders are permitted to vote, including the election of directors. There are no cumulative voting rights. Accordingly, holders of a majority of the total votes entitled to vote in an election of directors will be able to elect all of the directors standing for election. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of the common stock will share equally on a per share basis any dividends when, as and if declared by the board of directors out of funds legally available for that purpose. If we are liquidated, dissolved or wound up, the holders of our common stock will be entitled to a ratable share of any distribution to stockholders, after satisfaction of all of our liabilities and of the prior rights of any outstanding class of our preferred stock. Our common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of our common stock are fully paid and nonassessable.

Preferred Stock

Our board of directors has the authority, without stockholder approval, to issue shares of preferred stock from time to time in one or more series, and to fix the number of shares and terms of each such series. The board may determine the designation and other terms of each series, including the following:

• dividend rates;

• whether dividends will be cumulative or non-cumulative;

• redemption rights;

• liquidation rights;

• sinking fund provisions;

• conversion or exchange rights; and

• voting rights.

The issuance of preferred stock, while providing us with flexibility in connection with possible acquisitions and other transactions, could adversely affect the voting power of holders of our common stock. It could also affect the likelihood that holders of our common stock will receive dividend payments and payments upon liquidation.

The issuance of shares of preferred stock, or the issuance of rights to purchase shares of preferred stock, could be used to discourage an attempt to obtain control of our company. For example, if, in the exercise of its fiduciary obligations, our board of directors were to determine that a takeover proposal was not in the best interest of our stockholders, the board could authorize the issuance of a series of preferred stock containing class

20

voting rights that would enable the holder or holders of this series to prevent a change of control transaction or make it more difficult. Alternatively, a change of control transaction deemed by the board to be in the best interest of our stockholders could be facilitated by issuing a series of preferred stock having sufficient voting rights to provide a required percentage vote of the stockholders.

The prospectus supplement relating to any series of preferred stock that we may offer will include specific terms relating to the offering. We will file a form of certificate of designation with the SEC, and you should read the certificate of designation for provisions that may be important to you. The applicable prospectus supplement will summarize the general terms of any such series of preferred stock.

Charter and Bylaw Provisions

Election and Removal of Directors

Our board of directors consists of between one and 11 directors, excluding any directors elected by holders of preferred stock pursuant to provisions applicable in the case of defaults. The exact number of directors will be fixed from time to time by resolution of the board. Our board of directors is divided into three classes serving staggered three-year terms, with only one class being elected each year by our stockholders. At each annual meeting of stockholders, directors will be elected to succeed the class of directors whose terms have expired. This system of electing and removing directors may discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors. In addition, no director may be removed except for cause, and directors may be removed for cause by an affirmative vote of shares representing a majority of the shares then entitled to vote at an election of directors. Any vacancy occurring on the board of directors and any newly created directorship may only be filled by a majority of the remaining directors in office.

Stockholder Meetings

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that special meetings of our stockholders may be called only by the chairman of our board of directors or a majority of the directors. Our amended and restated certificate of incorporation and our amended and restated bylaws specifically deny any power of any other person to call a special meeting.

Stockholder Action by Written Consent

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that holders of our common stock will not be able to act by written consent without a meeting, unless such consent is unanimous.

Amendment of Certificate of Incorporation

The provisions of our amended and restated certificate of incorporation described above under “—Election and Removal of Directors,” “—Stockholder Meetings” and “—Stockholder Action by Written Consent” may be amended only by the affirmative vote of holders of at least 75% of the voting power of our outstanding shares of voting stock, voting together as a single class. The affirmative vote of holders of at least a majority of the voting power of our outstanding shares of stock is generally required to amend other provisions of our amended and restated certificate of incorporation.

Amendment of Bylaws

Our amended and restated bylaws may generally be altered, amended or repealed, and new bylaws may be adopted, with:

• the affirmative vote of a majority of directors present at any regular or special meeting of the board of directors called for that purpose, provided that any alteration, amendment or repeal of, or adoption of

21

any bylaw inconsistent with specified provisions of the bylaws, including those related to special and annual meetings of stockholders, action of stockholders by written consent, classification of the board of directors, nomination of directors, special meetings of directors, removal of directors, committees of the board of directors and indemnification of directors and officers, requires the affirmative vote of at least 75% of all directors in office at a meeting called for that purpose; or

• the affirmative vote of holders of 75% of the voting power of our outstanding shares of voting stock, voting together as a single class.

Other Limitations on Stockholder Actions

Our amended and restated bylaws also impose some procedural requirements on stockholders who wish to:

• make nominations in the election of directors;

• propose that a director be removed;

• propose any repeal or change in our bylaws; or

• propose any other business to be brought before an annual or special meeting of stockholders.

Under these procedural requirements, in order to bring a proposal before a meeting of stockholders, a stockholder must deliver timely notice of a proposal pertaining to a proper subject for presentation at the meeting to our corporate secretary along with the following:

• a description of the business or nomination to be brought before the meeting and the reasons for conducting such business at the meeting;

• the stockholder’s name and address;

• the number of shares beneficially owned by the stockholder and evidence of such ownership; and

• the names and addresses of all persons with whom the stockholder is acting in concert and a description of all arrangements and understandings with those persons, and the number of shares such persons beneficially own.

To be timely, a stockholder must generally deliver notice:

• in connection with an annual meeting of stockholders, not less than 120 nor more than 180 days prior to the date on which the annual meeting of stockholders was held in the immediately preceding year, but in the event that the date of the annual meeting is more than 30 days before or more than 60 days after the anniversary date of the preceding annual meeting of stockholders, a stockholder notice will be timely if received by us not later than the close of business on the later of (1) the 120th day prior to the annual meeting and (2) the 10th day following the day on which we first publicly announce the date of the annual meeting; or

• in connection with the election of a director at a special meeting of stockholders, not less than 40 nor more than 60 days prior to the date of the special meeting, but in the event that less than 55 days’ notice or prior public disclosure of the date of the special meeting of the stockholders is given or made to the stockholders, a stockholder notice will be timely if received by us not later than the close of business on the 10th day following the day on which a notice of the date of the special meeting was mailed to the stockholders or the public disclosure of that date was made.

In order to submit a nomination for our board of directors, a stockholder must also submit any information with respect to the nominee that we would be required to include in a proxy statement, as well as some other information. If a stockholder fails to follow the required procedures, the stockholder’s proposal or nominee will be ineligible and will not be voted on by our stockholders.

22

Limitation on Liability of Directors

Our amended and restated certificate of incorporation provides that no director will be personally liable to us or our stockholders for monetary damages for breach of fiduciary duties as a director, except as required by applicable law, as in effect from time to time. Currently, Delaware law requires that liability be imposed for the following:

• any breach of the director’s duty of loyalty to our company or our stockholders;

• any act or omission not in good faith or which involved intentional misconduct or a knowing violation of law;

• unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; and

• any transaction from which the director derived an improper personal benefit.

Our amended and restated bylaws provide that, to the fullest extent permitted by law, we will indemnify any officer or director of our company against all damages, claims and liabilities arising out of the fact that the person is or was our director or officer, or served any other enterprise at our request as a director, officer, employee, agent or fiduciary. We will reimburse the expenses, including attorneys’ fees, incurred by a person indemnified by this provision when we receive an undertaking to repay such amounts if it is ultimately determined that the person is not entitled to be indemnified by us. Amending this provision will not reduce our indemnification obligations relating to actions taken before an amendment.

Anti-Takeover Effects of Some Provisions

Some provisions of our amended and restated certificate of incorporation and amended and restated bylaws could make the following more difficult:

• acquisition of control of us by means of a proxy contest or otherwise; or

• removal of our incumbent officers and directors.

These provisions, as well as our ability to issue preferred stock, are designed to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us, and that the benefits of this increased protection outweigh the disadvantages of discouraging those proposals, because negotiation of those proposals could result in an improvement of their terms.

Transactions and Corporate Opportunities

Our amended and restated certificate of incorporation includes provisions that regulate and define the conduct of specified aspects of the business and affairs of our company. These provisions serve to determine and delineate the respective rights and duties of our company, our principal stockholder, TTWF LP, and its direct and indirect equity owners and directors, officers, employees, partners or equity owners of such entities (the “principal stockholder affiliates”), and some of our directors and officers in anticipation of the following:

• the principal stockholder affiliates serving as our directors and/or officers;

• the principal stockholder affiliates engaging in lines of business that are the same as, or similar to, our lines of business;

• the principal stockholder affiliates having an interest in the same areas of corporate opportunity as we have; and

• we and the principal stockholder affiliates engaging in material business transactions.

23

We may enter into agreements with the principal stockholder affiliates to engage in any transaction. We may also enter into agreements with the principal stockholder affiliates to compete or not to compete with each other, including agreements to allocate, or to cause our directors, officers and employees and the principal stockholder affiliates to allocate, opportunities between the principal stockholder affiliates and us. Our amended and restated certificate of incorporation provides that no such agreement will be considered contrary to any fiduciary duty of the principal stockholder affiliates, as our direct and indirect controlling stockholders, or our directors, officers or employees. Neither the principal stockholder affiliates nor any of our directors, officers or employees who are also principal stockholder affiliates are under any fiduciary duty to us to refrain from acting on our behalf or on behalf of the principal stockholder affiliates in respect of any such agreement or transaction. These provisions are generally subject to the corporate opportunity obligations described below with which the principal stockholder affiliates and our officers and directors who are also principal stockholder affiliates must comply.

Under our amended and restated certificate of incorporation, the principal stockholder affiliates have no duty to refrain from engaging in activities or lines of business similar to ours or from doing business with any of our clients, customers or vendors and, except as discussed in the above paragraph, the principal stockholder affiliates will not be liable to us or our stockholders for breach of any fiduciary duty as a stockholder by reason of any of these activities. In addition, if the principal stockholder affiliates or one of our directors or officers who is also a principal stockholder affiliate acquires knowledge of a potential transaction or matter which may be a corporate opportunity for both our company and the principal stockholder affiliates, then neither the principal stockholder affiliates nor any such person will have a duty to communicate or offer this corporate opportunity to us and will not be liable to us or our stockholders for breach of any fiduciary duty by reason of the fact that the principal stockholder affiliates pursue or acquire the corporate opportunity for themselves, direct the corporate opportunity to another person or do not communicate information regarding the corporate opportunity to us, so long as the principal stockholder affiliates act in a manner consistent with the following policy: A corporate opportunity offered to the principal stockholder affiliates or to any person who is one of our officers or directors and who is also a principal stockholder affiliate will belong to the principal stockholder affiliates, unless the opportunity was expressly offered in writing to the principal stockholder affiliates solely in their capacity as direct and indirect stockholders of our company or to that person solely in his or her capacity as one of our directors or officers.

Anyone becoming one of our stockholders will be deemed to have notice of and consented to these provisions of our amended and restated certificate of incorporation. Our amended and restated certificate of incorporation provides that in no event shall any amendment of these provisions subject any principal stockholder affiliate to liability for any act or omission occurring prior to such amendment for which such person would be deemed not to be liable under these provisions prior to such amendment.

Delaware Business Combination Statute

We have expressly elected not to be subject to Section 203 of the General Corporation Law of the State of Delaware, which is described below. However, our stockholders can amend our amended and restated certificate of incorporation and amended and restated bylaws to elect to be subject to Section 203. Section 203 provides that, subject to specified exceptions, an interested stockholder of a Delaware corporation is not permitted to engage in any business combination, including mergers or consolidations or acquisitions of additional shares of the corporation, with the corporation for a three-year period following the time that stockholder became an interested stockholder, unless one of the following conditions is met:

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

• upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, other than statutorily excluded shares; or

24

• on or subsequent to the time the stockholder became an interested stockholder, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders by the affirmative vote of at least 66 ²⁄₃% of the outstanding voting stock which is not owned by the interested stockholder.

Except as otherwise set forth in Section 203, “interested stockholder” means:

• any person that is the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date of determination; and

• the affiliates and associates of any such person.

If we ever become subject to Section 203, it may be more difficult for a person who is an interested stockholder to effect various business combinations with us for the applicable three-year period. Section 203, if it becomes applicable, also may have the effect of preventing changes in our management. It is possible that Section 203, if it becomes applicable, could make it more difficult to accomplish transactions which our stockholders may otherwise deem to be in their best interests. The provisions of Section 203, if it becomes applicable, may cause persons interested in acquiring us to negotiate in advance with our board of directors. The restrictions on business combinations set forth in Section 203 are not applicable to the principal stockholder so long as the principal stockholder holds 15% or more of our outstanding shares of common stock. Because we are not currently subject to Section 203, the principal stockholder, as a controlling stockholder, may find it easier to sell its controlling interest to a third party because Section 203 would not apply to the third party.

Listing of Common Stock

Our common stock is listed on the New York Stock Exchange under the symbol “WLK.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company.

25

DESCRIPTION OF WARRANTS

We will issue warrants under one or more warrant agreements between us and a warrant agent that we will name in the applicable prospectus supplement.

The prospectus supplement relating to any warrants that we may offer will include specific terms relating to the offering.

SELLING STOCKHOLDER

In addition to covering the issuance and sale of securities by us, this prospectus covers the possible sale from time to time of up to 4,500,000 shares of our common stock by the selling stockholder listed below. As used in this prospectus, “selling stockholder” includes the successors-in-interest, donees, transferees or others who may later hold the selling stockholder’s interests and who will be named in the applicable supplement to this prospectus.

The following table sets forth information as of March 14, 2016 regarding the beneficial ownership of the common stock held by the selling stockholder. Since the selling stockholder may sell none, all, or a portion of the 4,500,000 shares of our common stock included in the prospectus, no meaningful estimate can be given as to the amount or percentage of shares that will be held by the selling stockholder after completion of any sale by the selling stockholder.

Name and Address	Number of Shares		Percent of Stock (1)
TTWF LP (2)(3)		92,010,554		71.4	%

(1) Calculated as of September 1, 2016 based on 128,854,315 shares of common stock outstanding.

(2) The address of the selling stockholder is 2801 Post Oak Boulevard, Houston, Texas 77056. The selling stockholder may be deemed an “underwriter” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), with respect to sales of the shares listed above.

(3) Two trusts for the benefit of members of the Chao family, including James Chao, Dorothy C. Jenkins and Albert Chao, are the managers of TTWFGP LLC, a Delaware limited liability company, which is the general partner of TTWF LP. The limited partners of TTWF LP are five trusts principally for the benefit of members of the Chao family, including James Chao, Dorothy C. Jenkins and Albert Chao and two corporations owned, indirectly or directly, by certain of these trusts and by other entities owned by members of the Chao family, including James Chao, Dorothy C. Jenkins and Albert Chao. TTWF LP and TTWFGP LLC each have shared voting power and shared dispositive power over 92,010,554 shares of our common stock. As of March 14, 2016, James Chao had sole voting power and sole dispositive power over 181,581 shares of our common stock and shared voting power and shared dispositive power over 92,010,554 shares of our common stock. Dorothy C. Jenkins had sole voting power and sole dispositive power over 61,007 shares of our common stock and shared voting power and shared dispositive power over 92,010,554 shares of our common stock. Albert Chao had sole voting power and sole dispositive power over 922,471 shares of our common stock and shared voting power and shared dispositive power over 92,010,554 shares of our common stock. James Chao, Dorothy C. Jenkins and Albert Chao disclaim beneficial ownership of the 92,010,554 shares of our common stock held by TTWF LP except to the extent of their respective pecuniary interest therein.

Registration Rights Agreement

We are party to a registration rights agreement with the selling stockholder under which we have agreed, at the request of the selling stockholder, to use our best efforts to register shares of our common stock that are held by the selling stockholder for public sale under the Securities Act. As long as the selling stockholder owns a majority of the voting power of our outstanding common stock, there is no limit to the number of registrations that it may request. Once the selling stockholder owns less than a majority of the voting power of our outstanding common stock, it can request a total of five additional registrations. We have also agreed in the registration rights agreement to provide the selling stockholder and its permitted transferees with “piggy-back” rights to include its shares in registrations of our common stock under the Securities Act. There is no limit on the number of these “piggy-back” registrations in which the selling stockholder may request its shares be included. These rights will terminate once the selling stockholder is able to dispose of all of its shares of our common stock within a three-month period pursuant to the exemption from registration provided under Rule 144 of the Securities Act. We have agreed to cooperate in these registrations and related offerings. We and the selling stockholder have agreed to restrictions on the ability of each party to sell securities following registrations by either party. The shares of our common stock that may be sold by the selling stockholder hereunder are included in this prospectus pursuant to the registration rights agreement.

27

PLAN OF DISTRIBUTION

We and the selling stockholder may sell the securities in and outside the United States (a) through underwriters or dealers, (b) directly to purchasers or (c) through agents. The applicable prospectus supplement will include the following information:

• the terms of the offering;

• the names of any underwriters or agents;

• the purchase price of the securities from us or the selling stockholder and, if the purchase price is not payable in U.S. dollars, the currency, currency unit or composite currency in which the purchase price is payable;

• the net proceeds to us or the selling stockholder from the sale of securities;

• any delayed delivery arrangements;

• any underwriting discounts, commissions and other items constituting underwriters’ compensation;

• the initial public offering price;

• any discounts or concessions allowed or reallowed or paid to dealers; and

• any commissions paid to agents.

Sale Through Underwriters or Dealers

If we or the selling stockholder 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 the applicable 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 offered 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 reallowed 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 also may impose a penalty bid, which means that 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 the 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, the underwriters may discontinue these activities at any time.

If we or the selling stockholder use dealers in the sale of securities, the securities will be sold directly 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 applicable prospectus supplement the names of the dealers and the terms of the transaction.

Direct Sales and Sales Through Agents

We or the selling stockholder may sell the securities directly. In that event, no underwriters or agents would be involved. We or the selling stockholder may also sell the securities through agents designated from time to

28

time. In the applicable prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable by us or the selling stockholder to the agent. Unless we inform you otherwise in the applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We or the selling stockholder 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 or the selling stockholder will describe the terms of any such sales in the applicable prospectus supplement.

Private Sales

The shares of our common stock covered by this prospectus that may be sold by the selling stockholder qualify for sale pursuant to Rule 144 under the Securities Act and may be sold by the selling stockholder under Rule 144 rather than pursuant to this prospectus.

Delayed Delivery Contracts

If we so indicate in the applicable prospectus supplement, we or the selling stockholder 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 the applicable prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

Remarketing

We may offer and sell any of the securities in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise, by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm in the applicable prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act.

Derivative Transactions

We or the selling stockholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock.

We, the selling stockholder or one of our respective affiliates may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus. Such financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities offered by this prospectus or otherwise.

The third parties in any of the sale transactions described above will be underwriters and will be identified in the applicable prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus forms a part.

29

General Information

We or the selling stockholder may have agreements with the agents, dealers and underwriters to indemnify them against certain 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 be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses.

Pursuant to the registration rights agreement described under “Selling Stockholder,” we have agreed to pay all of the costs, fees and expenses incurred by us incident to our registration of the resale of the selling stockholder’s common stock, as well as legal fees and expenses of counsel to the selling stockholder. We will not pay any commissions, fees and discounts of underwriters, brokers, dealers and agents with respect to shares of our common stock sold by the selling stockholder.

30

LEGAL OPINIONS

Item 15. Indemnification of Directors and Officers.

Delaware law permits a corporation to adopt a provision in its certificate of incorporation eliminating or limiting the personal liability of a director, but not an officer in his or her capacity as such, to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except that such provision shall not eliminate or limit the liability of a director for (1) any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) liability under section 174 of the Delaware General Corporation Law (the “DGCL”) for unlawful payment of dividends or stock purchases or redemptions or (4) any transaction from which the director derived an improper personal benefit.

The amended and restated certificate of incorporation of Westlake provides that, to the fullest extent of Delaware law, no Westlake director shall be liable to Westlake or its stockholders for monetary damages for breach of fiduciary duty as a director.

Under Delaware law, a corporation may indemnify any person who was or is a party or is threatened to be made a party to any type of proceeding, other than an action by or in the right of the corporation, because he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation a director, officer, employee or agent of another corporation or other entity, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred in

II-1

connection with such proceeding if: (1) he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and (2) with respect to any criminal proceeding, he or she had no reasonable cause to believe that his or her conduct was unlawful. A corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit brought by or in the right of the corporation because he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other entity, against expenses, including attorneys’ fees, actually and reasonably incurred in connection with such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification will be made if the person is found liable to the corporation unless, in such a case, the court determines the person is nonetheless entitled to indemnification for such expenses. A corporation must also indemnify a present or former director or officer who has been successful on the merits or otherwise in defense of any proceeding, or in defense of any claim, issue or matter therein, against expenses, including attorneys’ fees, actually and reasonably incurred by him or her. Expenses, including attorneys’ fees, incurred by a director or officer, or any employees or agents as deemed appropriate by the board of directors, in defending civil or criminal proceedings may be paid by the corporation in advance of the final disposition of such proceedings upon receipt of an undertaking by or on behalf of such director, officer, employee or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the corporation. The Delaware law regarding indemnification and the advancement of expenses is not exclusive of any other rights a person may be entitled to under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

Under the DGCL, the termination of any proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that a person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, had reasonable cause to believe that his or her conduct was unlawful.

Delaware law also provides that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other entity, against any liability asserted against and incurred by such person, whether or not the corporation would have the power to indemnify such person against such liability.

Westlake’s amended and restated certificate of incorporation and amended and restated bylaws authorize indemnification of any person entitled to indemnity under law to the full extent permitted by law.

Item 17. Undertakings.

(a) The undersigned registrant 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;

(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 Commission pursuant to Rule 424(b) of the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(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;

II-3

provided, however, that the undertakings set forth in paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission 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.

(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.

(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 to any purchaser:

(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

(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.

(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:

(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.

II-4

(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 Section 13(a) or Section 15(d) of the 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 and 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.

(d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee under an Indenture to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939 (the “Act”) in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 2.03) set forth, or determined in the manner provided, in the Officers’ Certificate or Company Order referred to above or in any such indenture supplemental hereto.

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action, together with such Board Resolution, shall be set forth in an Officers’ Certificate or certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or Company Order setting forth the terms of the series.

SECTION 2.02. Denominations.

The Securities of each series shall be issuable in such denominations as shall be specified as contemplated by Section 2.01. In the absence of any such provisions with respect to the Securities of any series, the Securities of such series denominated in Dollars shall be issuable in denominations of $1,000 and any integral multiples thereof.

SECTION 2.03. Forms Generally.

The Securities of each series shall be in fully registered form and in substantially such form or forms (including temporary or permanent global form) established by or pursuant to a Board Resolution or in one or more indentures supplemental hereto. The Securities may have notations, legends or endorsements required by law, securities exchange rule, the Company’s certificate of incorporation, bylaws or other similar governing documents, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). A copy of the Board Resolution establishing the form or forms of Securities of any series shall be delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 2.04 for the authentication and delivery of such Securities.

The definitive Securities of each series shall be printed, lithographed or engraved on steel engraved borders or may be produced in any other manner, all as determined by the Officers executing such Securities, as evidenced by their execution thereof.

15

The Trustee’s certificate of authentication shall be in substantially the following form:

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

[                                                  ], as Trustee
By:
	Authorized Officer”.

SECTION 2.04. Execution, Authentication, Delivery and Dating.

Two Officers of the Company shall sign the Securities on behalf of the Company by manual or facsimile signature.

If an Officer of the Company whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless.

A Security shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence that the Security has been authenticated under this Indenture. Notwithstanding the foregoing, if any Security has been authenticated and delivered hereunder but never issued and sold by the Company, and the Company delivers such Security to the Trustee for cancellation as provided in Section 2.13, together with a written statement (which need not comply with Section 11.05 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, and the Trustee shall authenticate and deliver such Securities for original issue upon a Company Order for the authentication and delivery of such Securities or pursuant to such procedures acceptable to the Trustee as may be specified from time to time by Company Order. Such order shall specify the amount of the Securities to be authenticated, the date on which the original issue of Securities is to be authenticated, the name or names of the initial Holder or Holders and any other terms of the Securities of such series not otherwise determined. If provided for in such procedures, such Company Order may authorize (1) authentication and delivery of Securities of such series for original issue from time to time, with certain terms (including, without limitation, the Maturity dates or dates, original issue date or dates and interest rate or rates) that differ from Security to Security and (2) may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly authorized agent, which instructions shall be promptly confirmed in writing.

16

If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Section 2.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive (in addition to the Company Order referred to above and the other documents required by Section 11.04), and (subject to Section 7.01) shall be fully protected in relying upon:

(a) an Officers’ Certificate of the Company setting forth the Board Resolution and, if applicable, an appropriate record of any action taken pursuant thereto, as contemplated by the last paragraph of Section 2.01; and

(b) an Opinion of Counsel to the effect that:

(i) the form of such Securities has been established in conformity with the provisions of this Indenture;

(ii) the terms of such Securities have been established in conformity with the provisions of this Indenture; and

(iii) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or other similar laws in effect from time to time affecting the rights of creditors generally, and the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Officers’ Certificate and Opinion of Counsel at the time of issuance of each such Security, but such Officers’ Certificate and Opinion of Counsel shall be delivered at or before the time of issuance of the first Security of the series to be issued.

The Trustee shall not be required to authenticate such Securities if the issuance of such Securities pursuant to this Indenture would affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the Trustee.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company.

17

Each Security shall be dated the date of its authentication.

SECTION 2.05. Registrar and Paying Agent.

The Company shall maintain an office or agency for each series of Securities where Securities of such series may be presented for registration of transfer or exchange (“Registrar”) and an office or agency where Securities of such series may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Securities of such series and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. The Company may change any Paying Agent or Registrar without notice to any Holder. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any Subsidiary may act as Paying Agent or Registrar.

The Company initially appoints the Trustee as Registrar and Paying Agent.

SECTION 2.06. Paying Agent to Hold Money in Trust.

The Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of, premium, if any, or interest on or any Additional Amounts with respect to Securities and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed. Upon payment over to the Trustee and upon accounting for any funds disbursed, the Paying Agent (if other than the Company or a Subsidiary of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Each Paying Agent shall otherwise comply with TIA § 317(b).

SECTION 2.07. Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar with respect to a series of Securities, the Company shall furnish to the Trustee at least five Business Days before each Interest Payment Date with respect to such series of Securities, and at such other times as the Trustee may request

18

in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of such series, and the Company shall otherwise comply with TIA § 312(a).

SECTION 2.08. Transfer and Exchange.

Except as set forth in Section 2.17 or as may be provided pursuant to Section 2.01:

When Securities of any series are presented to the Registrar with the request to register the transfer of such Securities or to exchange such Securities for an equal principal amount of Securities of the same series of like tenor and of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements and the requirements of this Indenture for such transactions are met; provided, however, that the Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instruction of transfer in form reasonably satisfactory to the Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing, on which instruction the Registrar can rely.

To permit registrations of transfers and exchanges, the Company shall execute Securities and the Trustee shall authenticate such Securities at the Registrar’s written request and submission of the Securities or Global Securities. No service charge shall be made to a Holder for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or similar governmental charge payable upon exchanges pursuant to Section 2.12, 3.07 or 9.05). The Trustee shall authenticate Securities in accordance with the provisions of Section 2.04. Notwithstanding any other provisions of this Indenture to the contrary, the Company shall not be required to register the transfer or exchange of (a) any Security selected for redemption in whole or in part pursuant to Article III, except the unredeemed portion of any Security being redeemed in part, or (b) any Security during the period beginning 15 Business Days prior to the mailing of notice of any offer to repurchase Securities of the series required pursuant to the terms thereof or of redemption of Securities of a series to be redeemed and ending at the close of business on the day of mailing.

SECTION 2.09. Replacement Securities.

If any mutilated Security is surrendered to the Trustee, or if the Holder of a Security claims that the Security has been destroyed, lost or stolen and the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of such Security, the Company shall issue and the Trustee shall authenticate a replacement Security of the same series if the Trustee’s requirements are met. If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. If required by the Trustee or the Company, such Holder must furnish an indemnity bond that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent or any authenticating agent from any loss that any of them may suffer if a Security is replaced. The Company and the Trustee may charge a Holder for their expenses in replacing a Security.

19

Every replacement Security is an additional obligation of the Company.

SECTION 2.10. Outstanding Securities.

The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee hereunder and those described in this Section 2.10 as not outstanding.

If a Security is replaced pursuant to Section 2.09, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser.

If the principal amount of any Security is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to accrue.

A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

SECTION 2.11. Original Issue Discount, Foreign-Currency Denominated and Treasury Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any direction, amendment, supplement, waiver or consent, (a) the principal amount of an Original Issue Discount Security shall be the principal amount thereof that would be due and payable as of the date of such determination upon acceleration of the Maturity thereof pursuant to Section 6.02, (b) the principal amount of a Security denominated in a foreign currency shall be the Dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of New York for cable transfers for such currency, as such rate is certified for customs purposes by the Federal Reserve Bank of New York (the “Exchange Rate”) on the date of original issuance of such Security, of the principal amount (or, in the case of an Original Issue Discount Security, the Dollar equivalent, as determined by the Company by reference to the Exchange Rate on the date of original issuance of such Security, of the amount determined as provided in (a) above), of such Security and (c) Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or of such other obligor shall be disregarded, except that, for the purpose of determining whether the Trustee shall be protected in relying upon any such direction, amendment, supplement, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.12. Temporary Securities.

Until definitive Securities of any series are ready for delivery, the Company may prepare and execute temporary Securities and the Trustee shall authenticate such temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and execute definitive Securities and the Trustee shall authenticate such definitive Securities in exchange for temporary Securities. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

20

SECTION 2.13. Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, payment or redemption or for credit against any sinking fund payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, redemption, replacement or cancellation or for credit against any sinking fund. Unless the Company shall direct in writing that canceled Securities be returned to it, after written notice to the Company all canceled Securities held by the Trustee shall be disposed of in accordance with the usual disposal procedures of the Trustee, and the Trustee shall maintain a record of their disposal. The Company may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation.

SECTION 2.14. Payments; Defaulted Interest.

Unless otherwise provided as contemplated by Section 2.01, interest (except defaulted interest) on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Persons who are registered Holders of that Security at the close of business on the record date next preceding such Interest Payment Date, even if such Securities are canceled after such record date and on or before such Interest Payment Date. The Holder must surrender a Security to a Paying Agent to collect principal payments. Unless otherwise provided with respect to the Securities of any series, the Company will pay the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities in Dollars. Such amounts shall be payable at the offices of the Trustee or any Paying Agent, provided that at the option of the Company, the Company may pay such amounts (1) by wire transfer with respect to Global Securities or (2) by check payable in such money mailed to a Holder’s registered address with respect to any Securities.

If the Company defaults in a payment of interest on the Securities of any series, the Company shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Securities of such series and in Section 4.01. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15 days before any special record date selected by the Company, the Company (or the Trustee, in the name of and at the expense of the Company upon 20 days’ prior written notice from the Company setting forth such special record date and the interest amount to be paid) shall mail to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

SECTION 2.15. Persons Deemed Owners.

The Company, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payments of principal of, premium (if any) or interest on or any Additional Amounts with respect to such Security and for all other purposes. None of the Company, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary.

21

SECTION 2.16. Computation of Interest.

Except as otherwise specified as contemplated by Section 2.01 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a year comprising twelve 30-day months.

SECTION 2.17. Global Securities; Book-Entry Provisions.

If Securities of a series are issuable in global form as a Global Security, as contemplated by Section 2.01, then, notwithstanding clause (11) of Section 2.01 and the provisions of Section 2.02, any such Global Security shall represent such of the outstanding Securities of such series as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, transfers or redemptions. Any endorsement of a Global Security to reflect the amount, or any increase or decrease in the amount, of outstanding Securities represented thereby shall be made by the Trustee (i) in such manner and upon instructions given by such Person or Persons as shall be specified in such Security or in a Company Order to be delivered to the Trustee pursuant to Section 2.04 or (ii) otherwise in accordance with written instructions or such other written form of instructions as is customary for the Depositary for such Security, from such Depositary or its nominee on behalf of any Person having a beneficial interest in such Global Security. Subject to the provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified in such Security or in the applicable Company Order. With respect to the Securities of any series that are represented by a Global Security, the Company authorize the execution and delivery by the Trustee of a letter of representations or other similar agreement or instrument in the form customarily provided for by the Depositary appointed with respect to such Global Security. Any Global Security may be deposited with the Depositary or its nominee, or may remain in the custody of the Trustee or the Security Custodian therefor pursuant to a FAST Balance Certificate Agreement or similar agreement between the Trustee and the Depositary. If a Company Order has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 11.05 and need not be accompanied by an Opinion of Counsel.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee or the Security Custodian as its custodian, or under such Global Security, and the Depositary may be treated by the Company, the Trustee or the Security Custodian and any agent of the Company, the Trustee or the Security Custodian as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a Global Security of a series may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action

22

that a Holder of Securities of such series is entitled to take under this Indenture or the Securities of such series and (ii) nothing herein shall prevent the Company, the Trustee or the Security Custodian, or any agent of the Company, the Trustee or the Security Custodian, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Security.

Notwithstanding Section 2.08, and except as otherwise provided pursuant to Section 2.01, transfers of a Global Security shall be limited to transfers of such Global Security in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred in accordance with the rules and procedures of the Depositary. Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if, and only if, either (1) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Global Security and a successor Depositary is not appointed by the Company within 90 days of such notice, (2) an Event of Default has occurred with respect to such series and is continuing and the Registrar has received a request from the Depositary to issue Securities in lieu of all or a portion of the Global Security (in which case the Company shall deliver Securities within 30 days of such request) or (3) the Company in its sole discretion determines not to have the Securities represented by a Global Security.

In connection with any transfer of a portion of the beneficial interests in a Global Security to beneficial owners pursuant to this Section 2.17, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the Global Security in an amount equal to the principal amount of the beneficial interests in the Global Security to be transferred, and the Company shall execute and the Trustee upon receipt of a Company Order for the authentication and delivery of Securities shall authenticate and deliver, one or more Securities of the same series of like tenor and amount.

In connection with the transfer of all of the beneficial interests in a Global Security to beneficial owners pursuant to this Section 2.17, the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interests in the Global Security, an equal aggregate principal amount of Securities of authorized denominations.

Neither the Company or the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Securities by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to such Securities. Neither the Company or the Trustee shall be liable for any delay by the Holder of the Global Security or the Depositary in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from such Holder of the Global Security or the Depositary for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Securities to be issued).

The provisions of the last sentence of the third paragraph of Section 2.04 shall apply to any Global Security if such Global Security was never issued and sold by the Company and the

23

Company delivers to the Trustee the Global Security together with written instructions (which need not comply with Section 11.05 and need not be accompanied by an Opinion of Counsel) with regard to the cancellation or reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of the third paragraph of Section 2.04.

Notwithstanding the provisions of Sections 2.03 and 2.14, unless otherwise specified as contemplated by Section 2.01, payment of principal of, premium (if any) and interest on and any Additional Amounts with respect to any Global Security shall be made to the Depositary.

The Company in issuing Securities of any series may use CUSIP numbers (if then generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Holders of Securities of such series; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities of such series or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities of such series, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP numbers.

Notwithstanding anything herein to the contrary, delivery or surrender of a Security shall not be required in the case of Global Securities in order to obtain the rights or benefits provided hereunder upon the delivery or surrender of a Security.

ARTICLE III

REDEMPTION

SECTION 3.01. Applicability of Article.

Securities of any series that are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 2.01 for Securities of any series) in accordance with this Article III.

SECTION 3.02. Notice to the Trustee.

If the Company elects to redeem Securities of any series pursuant to this Indenture, it shall notify the Trustee of the Redemption Date and the principal amount of Securities of such series to be redeemed. The Company shall so notify the Trustee at least 45 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee) by delivering to the Trustee an Officers’ Certificate stating that such redemption will comply with the provisions of this Indenture and of the Securities of such series. Any such notice may be canceled at any time prior to the mailing of such notice of such redemption to any Holder and shall thereupon be void and of no effect.

SECTION 3.03. Selection of Securities To Be Redeemed.

If less than all of the Securities of any series are to be redeemed (unless all of the Securities of such series of a specified tenor are to be redeemed), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee

24

from the outstanding Securities of such series (and tenor) not previously called for redemption, either pro rata, by lot or by such other method as the Trustee shall deem appropriate in accordance with industry standards at the time of such redemption and that may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series or of the principal amount of Global Securities of such series; provided that, if at the time of redemption such Securities are registered as a Global Security, the Depositary shall determine, in accordance with its procedures, the principal amount of such Securities held by each beneficial owner of Securities to be redeemed.

The Trustee shall promptly notify the Company and the Registrar in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities shall relate, in the case of any of the Securities redeemed or to be redeemed only in part, to the portion of the principal amount thereof which has been or is to be redeemed.

SECTION 3.04. Notice of Redemption.

Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 days (or not less than 15 days in the case of convertible Securities) nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at the address of such Holder appearing in the register of Securities maintained by the Registrar.

All notices of redemption shall identify the Securities to be redeemed and shall state:

(1) the Redemption Date;

(2) the Redemption Price (or the method of calculating or determining the Redemption Price);

(3) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Securities is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Securities redeemed;

(4) if any Security is to be redeemed in part, the portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, upon surrender for cancellation of such Security to the Paying Agent, a new Security or Securities in the aggregate principal amount equal to the unredeemed portion thereof will be issued without charge to the Holder;

(5) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and the name and address of the Paying Agent;

25

(6) that the redemption is for a sinking or analogous fund, if such is the case;

(7) if such Securities are convertible into or exchangeable for capital stock, other debt securities (including Securities), warrants, other equity securities or any other securities or property of the Company or any other Person, the name and address of the conversion or exchange agent, the date on which the right to convert or exchange is terminated and the conversion or exchange rate; and

(8) the CUSIP number, if any, relating to such Securities.

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company’s written request, by the Trustee in the name and at the expense of the Company.

SECTION 3.05. Effect of Notice of Redemption.

Once notice of redemption is mailed, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon surrender to the Paying Agent, such Securities called for redemption shall be paid at the Redemption Price, but interest installments whose maturity is on or prior to such Redemption Date will be payable on the relevant Interest Payment Dates to the Holders of record at the close of business on the relevant record dates specified pursuant to Section 2.01.

SECTION 3.06. Deposit of Redemption Price.

By 11:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or the Paying Agent (or, if the Company is acting as the Paying Agent, segregate and hold in trust as provided in Section 2.06) an amount of money in same day funds sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on and any Additional Amounts with respect to, the Securities or portions thereof which are to be redeemed on that date, other than Securities or portions thereof called for redemption on that date which have been delivered by the Company to the Trustee for cancellation.

If the Company complies with the preceding paragraph, then, unless the Company defaults in the payment of such Redemption Price, interest on the Securities to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Securities are presented for payment, and the Holders of such Securities shall have no further rights with respect to such Securities except for the right to receive the Redemption Price upon surrender of such Securities. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal, premium, if any, any Additional Amounts, and, to the extent lawful, accrued interest thereon shall, until paid, bear interest from the Redemption Date at the rate specified pursuant to Section 2.01 or provided in the Securities or, in the case of Original Issue Discount Securities, such Securities’ yield to maturity.

26

SECTION 3.07. Securities Redeemed in Part.

Upon surrender to the Paying Agent of a Security to be redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge a new Security or Securities, of the same series and of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the unredeemed portion of the principal of the Security so surrendered that is not redeemed.

SECTION 3.08. Purchase of Securities.

Unless otherwise specified as contemplated by Section 2.01, the Company and any Affiliate of the Company may at any time purchase or otherwise acquire Securities in the open market or by private agreement. Any such acquisition shall not operate as or be deemed for any purpose to be a redemption of the indebtedness represented by such Securities. Any Securities purchased or acquired by the Company may be delivered to the Trustee and, upon such delivery, the indebtedness represented thereby shall be deemed to be satisfied. Section 2.13 shall apply to all Securities so delivered.

SECTION 3.09. Mandatory and Optional Sinking Funds.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund payment.” Unless otherwise provided by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 3.10. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of Securities of such series and by this Article III.

SECTION 3.10. Satisfaction of Sinking Fund Payments with Securities.

The Company may deliver outstanding Securities of a series (other than any previously called for redemption) and may apply as a credit Securities of a series that have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such series of Securities; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

SECTION 3.11. Redemption of Securities for Sinking Fund.

Not less than 45 days prior (unless a shorter period shall be satisfactory to the Trustee) to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers’ Certificate of the Company specifying the amount of the next ensuing

27

sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivery of or by crediting Securities of that series pursuant to Section 3.10 and will also deliver or cause to be delivered to the Trustee any Securities to be so delivered. Failure of the Company to timely deliver or cause to be delivered such Officers’ Certificate and Securities specified in this paragraph, if any, shall not constitute a default but shall constitute the election of the Company (i) that the mandatory sinking fund payment for such series due on the next succeeding sinking fund payment date shall be paid entirely in cash without the option to deliver or credit Securities of such series in respect thereof and (ii) that the Company will make no optional sinking fund payment with respect to such series as provided in this Section.

If the sinking fund payment or payments (mandatory or optional or both) to be made in cash on the next succeeding sinking fund payment date plus any unused balance of any preceding sinking fund payments made in cash shall exceed $100,000 (or the Dollar equivalent thereof based on the applicable Exchange Rate on the date of original issue of the applicable Securities) or a lesser sum if the Company shall so request with respect to the Securities of any particular series, such cash shall be applied on the next succeeding sinking fund payment date to the redemption of Securities of such series at the sinking fund redemption price together with accrued interest to the date fixed for redemption. If such amount shall be $100,000 (or the Dollar equivalent thereof as aforesaid) or less and the Company makes no such request then it shall be carried over until a sum in excess of $100,000 (or the Dollar equivalent thereof as aforesaid) is available. Not less than 30 days before each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 3.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 3.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 3.05, 3.06 and 3.07.

ARTICLE IV

COVENANTS

SECTION 4.01. Payment of Securities.

The Company shall pay the principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of each series on the dates and in the manner provided in the Securities of such series and in this Indenture. Principal, premium, interest and any Additional Amounts shall be considered paid on the date due if the Paying Agent (other than the Company or a Subsidiary) holds by 11:00 a.m., New York City time, on that date money deposited by the Company designated for and sufficient to pay all principal, premium, interest and any Additional Amounts then due.

The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium (if any), at a rate equal to the then applicable interest rate on the Securities to the extent lawful; and it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and any Additional Amount (without regard to any applicable grace period) at the same rate to the extent lawful.

SECTION 4.02. Maintenance of Office or Agency.

The Company will maintain in each Place of Payment for any series of Securities an office or agency (which may be an office of the Trustee, the Registrar or the Paying Agent) where Securities of that series may be presented for registration of transfer or exchange, where Securities of that series may be presented for payment and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. Unless otherwise designated by the Company by written notice to the Trustee, such office or agency shall be the office of the Trustee in The City of New York, which on the date hereof is located at 4 New York Plaza, 15th Floor, New York, New York 10004. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 4.03. SEC Reports; Financial Statements.

If this Indenture is qualified under the TIA, but not otherwise, the Company shall also comply with the provisions of TIA § 314(a).

(b) If the Company is not subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Company shall furnish to all Holders of Rule 144A Securities and prospective purchasers of Rule 144A Securities designated by the Holders of Rule 144A Securities, promptly upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) promulgated under the Securities Act of 1933, as amended.

(c) The Company intends to file the reports, information and documents referred to in Section 4.03(a) hereof with the SEC in electronic form pursuant to Regulation S-T promulgated by the SEC using the SEC’s Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system. The Company shall notify the Trustee in the manner prescribed herein of each such filing. The Trustee is hereby authorized and directed to access

29

the EDGAR system for purposes of retrieving the reports so filed. Compliance with the foregoing shall constitute delivery by the Company of such reports to the Trustee in compliance with the provisions of TIA § 314(a). The Trustee shall have no duty to search for or obtain any electronic or other filings that the Company makes with the SEC, regardless of whether such filings are periodic, supplemental or otherwise. Delivery of the reports, information and documents to the Trustee pursuant to this Section 4.03 shall be solely for the purposes of compliance with this Section 4.03 and with TIA § 314(a). The Trustee’s receipt of such reports, information and documents shall not constitute notice to it of the content thereof or of any matter determinable from the content thereof, including the Company’s compliance with any of its covenants hereunder, as to which the Trustee is entitled to rely upon Officers’ Certificates.

SECTION 4.04. Compliance Certificate.

(a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, a statement signed by the principal executive officer, principal financial officer or principal accounting officer of the Company, which need not constitute an Officers’ Certificate, complying with TIA § 314(a)(4) and stating that in the course of performance by the signing Officer of his duties as such Officer of the Company, he would normally obtain knowledge of the keeping, observing, performing and fulfilling by the Company, of its obligations under this Indenture, and further stating that to the best of his knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions hereof (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such Officer may have knowledge and what action the Company is taking or proposes to take with respect thereto).

(b) The Company shall, so long as Securities of any series are outstanding, deliver to the Trustee, as soon as practicable, but in no event more than five Business Days, after any Officer of the Company becoming aware of any Default or Event of Default under this Indenture, an Officers’ Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

SECTION 4.05. Corporate or Other Existence.

Subject to Article V, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its existence. This Section 4.05 shall not prohibit or restrict the Company from converting into a different form of legal entity.

30

SECTION 4.06. Waiver of Stay, Extension or Usury Laws.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive it from paying all or any portion of the principal of or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) the Company hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 4.07. Additional Amounts.

If the Securities of a series expressly provide for the payment of Additional Amounts, the Company will pay to the Holder of any Security of such series Additional Amounts as expressly provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received from the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.07 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section 4.07 and express mention of the payment of Additional Amounts (if applicable) in any provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

SECTION 4.08. Foreign Account Tax Compliance Act (FATCA).

The Trustee shall be entitled to deduct or withhold from payments under this Indenture to the extent necessary to comply with an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code and any regulations or agreements thereunder or official interpretations thereof (“FATCA”). To the extent permitted under applicable privacy law and if expressly authorized by any agreement between the Issuer and such holder or beneficial owner or by the terms of any tax certification, the Issuer hereby covenants with the Trustee that it will use commercially reasonable efforts to provide the Trustee with any relevant tax certification in the possession of the Issuer or other information identified by the Issuer in its sole discretion as relevant for FATCA withholding tax purposes that may be useful to assist the Trustee in determining whether or not the Trustee is obliged, in respect of any payments to be made by it pursuant to this Indenture, to make any withholding or deduction pursuant to FATCA.

ARTICLE VI

DEFAULTS AND REMEDIES

SECTION 6.01. Events of Default.

Unless either inapplicable to a particular series or specifically deleted or modified in or pursuant to the supplemental indenture or Board Resolution establishing such series of Securities or in the form of Security for such series, an “Event of Default,” wherever used herein with respect to Securities of any series, occurs if:

(1) the Company defaults in the payment of interest on or any Additional Amounts with respect to any Security of that series when the same becomes due and payable and such default continues for a period of 30 days;

32

(2) the Company defaults in the payment of (A) the principal of any Security of that series at its Maturity or (B) premium (if any) on any Security of that series when the same becomes due and payable;

(3) the Company defaults in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series, and such default continues for a period of 30 days;

(4) the Company fails to comply with any of its other covenants or agreements in, or provisions of, the Securities of such series or this Indenture (other than an agreement, covenant or provision that has expressly been included in this Indenture solely for the benefit of one or more series of Securities other than that series) which shall not have been remedied within the specified period after written notice, as specified in the last paragraph of this Section 6.01;

(5) the Company, pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary case;

(B) consents to the entry of an order for relief against it in an involuntary case;

(C) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property; or

(D) makes a general assignment for the benefit of its creditors;

(6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that remains unstayed and in effect for 90 days and that:

(A) is for relief against the Company as debtor in an involuntary case;

(B) appoints a Bankruptcy Custodian of the Company or a Bankruptcy Custodian for all or substantially all of the property of the Company; or

(C) orders the liquidation of the Company;

(7) any other Event of Default provided with respect to Securities of that series occurs.

The term “Bankruptcy Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law.

The Trustee shall not be deemed to know or have notice of any Default or Event of Default unless a trust officer at the Corporate Trust Office of the Trustee receives written notice at the Corporate Trust Office of the Trustee of such Default or Event of Default with specific reference to such Default or Event of Default.

33

When a Default or Event of Default is cured, it ceases.

Notwithstanding the foregoing provisions of this Section 6.01, if the principal of, premium (if any) or interest on or Additional Amounts with respect to any Security is payable in a currency or currencies (including a composite currency) other than Dollars and such currency or currencies are not available to the Company for making payment thereof due to the imposition of exchange controls or other circumstances beyond the control of the Company (a “Conversion Event”), the Company will be entitled to satisfy its obligations to Holders of the Securities by making such payment in Dollars in an amount equal to the Dollar equivalent of the amount payable in such other currency, as determined by the Company by reference to the Exchange Rate on the date of such payment, or, if such rate is not then available, on the basis of the most recently available Exchange Rate. Notwithstanding the foregoing provisions of this Section 6.01, any payment made under such circumstances in Dollars where the required payment is in a currency other than Dollars will not constitute an Event of Default under this Indenture.

Promptly after the occurrence of a Conversion Event, the Company shall give written notice thereof to the Trustee; and the Trustee, promptly after receipt of such notice, shall give notice thereof in the manner provided in Section 11.02 to the Holders. Promptly after the making of any payment in Dollars as a result of a Conversion Event, the Company shall give notice in the manner provided in Section 11.02 to the Holders, setting forth the applicable Exchange Rate and describing the calculation of such payments.

A Default under clause (4) or (7) of this Section 6.01 is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by such Default (or, in the case of a Default under clause (4) of this Section 6.01, if outstanding Securities of other series are affected by such Default, then at least 25% in principal amount of the then outstanding Securities so affected) notify the Company and the Trustee, of the Default, and the Company fails to cure the Default within 60 days after receipt of the notice. The notice must specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.”

SECTION 6.02. Acceleration.

If an Event of Default with respect to any Securities of any series at the time outstanding (other than an Event of Default specified in clause (5) or (6) of Section 6.01) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Securities of the series affected by such Event of Default (or, in the case of an Event of Default described in clause (4) of Section 6.01, if outstanding Securities of other series are affected by such Event of Default, then at least 25% in principal amount of the then outstanding Securities so affected) by notice to the Company and the Trustee, may declare the principal of (or, if any such Securities are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) and all accrued and unpaid interest on all then outstanding Securities of such series or of all series, as the case may be, to be due and payable. Upon any such declaration, the amounts due and payable on the Securities

34

shall be due and payable immediately. If an Event of Default specified in clause (5) or (6) of Section 6.01 hereof occurs, such amounts shall ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the then outstanding Securities of the series affected by such Event of Default or all series so affected, as the case may be, by written notice to the Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of or premium or interest on or any Additional Amounts with respect to the Securities) if (i) the rescission would not conflict with any judgment or decree, (ii) all existing Events of Default with respect to Securities of that series (or of all series, as the case may be) have been cured or waived, except nonpayment of principal, premium, interest or any Additional Amounts that has become due solely because of the acceleration, and (iii) the Trustee has been paid any amounts due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07.

SECTION 6.03. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, or premium, if any, or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 6.04. Waiver of Defaults.

Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the then outstanding Securities of any series or of all series affected thereby (acting as one class) by notice to the Trustee may waive an existing or past Default or Event of Default with respect to such series or all series so affected, as the case may be, and its consequences (including waivers obtained in connection with a tender offer or exchange offer for Securities of such series or all series so affected or a solicitation of consents in respect of Securities of such series or all series so affected, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities of such series or all series so affected (but the terms of such offer or solicitation may vary from series to series)), except (1) a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on or any Additional Amounts with respect to any Security or (2) a continued Default in respect of a provision that under Section 9.02 cannot be amended or supplemented without the consent of each Holder affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

SECTION 6.05. Control by Majority.

35

With respect to Securities of any series, the Holders of a majority in principal amount of the then outstanding Securities of such series may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it relating to or arising under an Event of Default described in clause (1), (2), (3) or (7) of Section 6.01, and with respect to all Securities, the Holders of a majority in principal amount of all the then outstanding Securities affected may direct in writing the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it not relating to or arising under such an Event of Default. However, the Trustee may refuse to follow any direction that conflicts with applicable law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders, or that may involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion from Holders directing the Trustee against all losses and expenses caused by taking or not taking such action.

SECTION 6.06. Limitations on Suits.

Subject to Section 6.07 hereof, a Holder of a Security of any series may pursue a remedy with respect to this Indenture or the Securities of such series, only if:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default with respect to such series;

(2) the Holders of at least 25% in principal amount of the then outstanding Securities of such series make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period, the Holders of a majority in principal amount of the Securities of such series do not give the Trustee a direction inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

SECTION 6.07. Rights of Holders to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of and premium, if any, and interest on and any Additional Amounts with respect to the Security, on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder.

36

SECTION 6.08. Collection Suit by Trustee.

If an Event of Default specified in clause (1) or (2) of Section 6.01 hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the amount of principal, premium (if any), interest and any Additional Amounts remaining unpaid on the Securities of the series affected by the Event of Default, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue interest, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of any committee of creditors, as may be necessary or advisable to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company or its creditors or properties and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Bankruptcy Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties which the Holders of the Securities may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. Priorities.

If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 7.07;

Second: to Holders for amounts due and unpaid on the Securities in respect of which or for the benefit of which such money has been collected, for principal, premium (if any), interest and any Additional Amounts ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal, premium (if any), interest and any Additional Amounts, respectively; and

37

Third: to the Company.

The Trustee, upon prior written notice to the Company, may fix record dates and payment dates for any payment to Holders pursuant to this Article VI.

To the fullest extent allowed under applicable law, if for the purpose of obtaining a judgment against the Company in any court it is necessary to convert the sum due in respect of the principal of, premium (if any) or interest on or Additional Amounts with respect to the Securities of any series (the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used for purposes of rendering the judgment shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the Business Day in The City of New York next preceding that on which final judgment is given. Neither the Company or the Trustee shall be liable for any shortfall nor shall it benefit from any windfall in payments to Holders of Securities under this Section 6.10 caused by a change in exchange rates between the time the amount of a judgment against it is calculated as above and the time the Trustee converts the Judgment Currency into the Required Currency to make payments under this Section 6.10 to Holders of Securities, but payment of such judgment shall discharge all amounts owed by the Company on the claim or claims underlying such judgment.

SECTION 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than 10% in principal amount of the then outstanding Securities of any series.

ARTICLE VII

TRUSTEE

SECTION 7.01. Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in such exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

38

(1) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(g) The permissive rights of the Trustee enumerated herein shall not be construed as duties.

SECTION 7.03. May Hold Securities.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or any of its Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. However, the Trustee is subject to Sections 7.10 and 7.11.

SECTION 7.04. Trustee’s Disclaimer.

40

SECTION 7.05. Notice of Defaults.

If a Default or Event of Default with respect to the Securities of any series occurs and is continuing and it is known to the Trustee, the Trustee shall mail to Holders of Securities of such series a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium (if any) and interest on and Additional Amounts or any sinking fund installment with respect to the Securities of such series, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Holders of Securities of such series.

SECTION 7.06. Reports by Trustee to Holders.

Within 60 days after each June 15 of each year after the execution of this Indenture, the Trustee shall mail to Holders of a series and the Company a brief report dated as of such reporting date that complies with TIA § 313(a); provided, however, that if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date with respect to a series, no report need be transmitted to Holders of such series. The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports if and as required by TIA §§ 313(c) and 313(d).

A copy of each report at the time of its mailing to Holders of a series of Securities shall be filed by the Company with the SEC and each securities exchange, if any, on which the Securities of such series are listed. The Company shall notify the Trustee if and when any series of Securities is listed on any securities exchange.

SECTION 7.07. Compensation and Indemnity.

The Company agrees to pay to the Trustee for its acceptance of this Indenture and services hereunder such compensation as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company agrees to reimburse the Trustee upon request for all reasonable fees, disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable fees, compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Company hereby indemnifies the Trustee and any predecessor Trustee against any and all loss, liability, damage, claim or expense, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, except as set forth in the next following paragraph. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

41

The Company shall not be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee’s negligence or bad faith.

To secure the payment obligations of the Company in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium (if any) and interest on and any Additional Amounts with respect to Securities of any series. Such lien and the Company’s obligations under this Section 7.07 shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this Indenture.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(5) or (6) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 7.08. Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

The Trustee may resign and be discharged at any time with respect to the Securities of one or more series by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Securities of any series may remove the Trustee with respect to the Securities of such series by so notifying the Trustee and the Company. The Company may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10;

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(3) a Bankruptcy Custodian or public officer takes charge of the Trustee or its property; or

(4) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, with respect to the Securities of one or more series, the Company shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series). Within one year after the successor Trustee with respect to the Securities of any series takes office, the Holders of a majority in principal amount of the Securities of such series then outstanding may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee with respect to the Securities of any series does not take office within 30 days after the retiring or removed Trustee resigns or is removed, the retiring or

42

removed Trustee (at the expense of the Company), the Company or the Holders of at least 10% in principal amount of the then outstanding Securities of such series may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

If the Trustee with respect to the Securities of a series fails to comply with Section 7.10, any Holder of Securities of such series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee with respect to the Securities of such series.

In case of the appointment of a successor Trustee with respect to all Securities, each such successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the retiring Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

In case of the appointment of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more (but not all) series shall execute and deliver an indenture supplemental hereto in which each successor Trustee shall accept such appointment and that (1) shall confer to each successor Trustee all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall confirm that all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee. Nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, and each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. Upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee shall have all the rights, powers and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. On request of the Company or any successor Trustee, such retiring Trustee shall transfer to such successor Trustee all property held by such retiring Trustee as Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. Such retiring Trustee shall, however, have the right to deduct its unpaid fees and expenses, including attorneys’ fees.

Notwithstanding replacement of the Trustee or Trustees pursuant to this Section 7.08, the obligations of the Company under Section 7.07 shall continue for the benefit of the retiring Trustee or Trustees.

SECTION 7.09. Successor Trustee by Merger, etc.

43

Subject to Section 7.10, if the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided, however, that in the case of a transfer of all or substantially all of its corporate trust business to another corporation, the transferee corporation expressly assumes all of the Trustee’s liabilities hereunder.

In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10. Eligibility; Disqualification.

There shall at all times be a Trustee hereunder which shall be a corporation or banking association organized and doing business under the laws of the United States, any State thereof or the District of Columbia and authorized under such laws to exercise corporate trust power, shall be subject to supervision or examination by Federal or State (or the District of Columbia) authority and shall have, or be a subsidiary of a bank or bank holding company having, a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition.

The Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee is subject to and shall comply with the provisions of TIA § 310(b) during the period of time required by this Indenture. Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA § 310(b).

SECTION 7.11. Preferential Collection of Claims Against the Company.

The Trustee is subject to and shall comply with the provisions of TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein.

ARTICLE VIII

DISCHARGE OF INDENTURE

(1) the Company has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for and dedicated solely to the benefit of the Holders of Securities of such series, (i) money in the currency in which payment of the Securities of such series is to be made in an amount, or (ii) Government Obligations with respect to such series, maturing as to principal and interest at such times and in such amounts as will ensure the availability of money in the currency in which payment of the Securities of such series is to be made in an amount or (iii) a combination thereof, that is sufficient, in the opinion (in the case of clauses (ii) and (iii)) of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay the principal of and premium (if any) and interest on all Securities of such series on each date that such principal, premium (if any) or interest is due and payable and (at the Stated Maturity thereof or upon redemption as provided in Section 8.01(e)) to pay all other sums payable by it hereunder; provided that the Trustee shall have been irrevocably instructed to apply such money and/or the proceeds of such Government Obligations to the payment of said principal, premium (if any) and interest with respect to the Securities of such series as the same shall become due;

(5) the Company has complied with any additional conditions specified pursuant to Section 2.01 to be applicable to the discharge of Securities of such series pursuant to this Section 8.01; and

46

(6) such deposit and discharge shall not cause the Trustee to have a conflicting interest as defined in TIA § 310(b).

In such event, this Indenture shall cease to be of further effect (except as set forth in this paragraph), and the Trustee, on demand of the Company, shall execute proper instruments acknowledging satisfaction and discharge under this Indenture. However, the Company’s obligations in Sections 2.05, 2.06, 2.07, 2.08, 2.09, 4.01, 4.02, 7.07, 7.08, and 8.04, the Trustee’s and Paying Agent’s obligations in Section 8.03 and the rights, powers, protections and privileges accorded the Trustee under Article VII shall survive until all Securities of such series are no longer outstanding.

After such irrevocable deposit made pursuant to this Section 8.01(b) and satisfaction of the other conditions set forth herein, the Trustee upon request shall acknowledge in writing the discharge of the Company’s obligations under this Indenture with respect to the Securities of such series except for those surviving obligations specified above.

(1) no Default or Event of Default under clauses (5) and (6) of Section 6.01 hereof shall have occurred at any time during the period ending on the 91st day after the date of deposit contemplated by Section 8.01(b) (it being understood that this condition shall not be deemed satisfied until the expiration of such period);

(2) unless otherwise specified with respect to Securities of such series as contemplated by Section 2.01, the Company has delivered to the Trustee an Opinion of Counsel from a nationally recognized counsel acceptable to the Trustee to the effect referred to in Section 8.01(b)(4) with respect to such legal defeasance, which opinion is based on (i) a private letter ruling issued by the United States Internal Revenue Service addressed to the Company, (ii) a published ruling of the United States Internal Revenue Service pertaining to a comparable form of transaction or (iii) a change in the applicable United States Federal income tax law (including regulations) after the date of this Indenture;

(d) If and to the extent additional or alternative means of satisfaction, discharge or defeasance of Securities of a series are specified to be applicable to such series as contemplated by Section 2.01, the Company may terminate any or all of its obligations under this Indenture with respect to Securities of a series and any or all of its obligations under the Securities of such series if it fulfills such other means of satisfaction and discharge as may be so specified, as contemplated by Section 2.01, to be applicable to the Securities of such series.

(e) If Securities of any series subject to subsection (a), (b), (c) or (d) of this Section 8.01 are to be redeemed prior to their Stated Maturity, whether pursuant to any optional redemption provisions or in accordance with any mandatory or optional sinking fund provisions, the terms of the applicable trust arrangement shall provide for such redemption, and the Company shall make such arrangements as are reasonably satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

SECTION 8.02. Application of Trust Money.

The Trustee or a trustee satisfactory to the Trustee and the Company shall hold in trust money or Government Obligations deposited with it pursuant to Section 8.01 hereof. It shall apply the deposited money and the money from Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of, premium (if any) and interest on and any Additional Amounts with respect to the Securities of the series with respect to which the deposit was made.

SECTION 8.03. Repayment to Company.

After payment to the Company, Holders entitled to the money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person, and all liability of the Trustee and the Paying Agent with respect to such money shall cease.

SECTION 8.04. Reinstatement.

If the Trustee or the Paying Agent is unable to apply any money or Government Obligations deposited with respect to Securities of any series in accordance with Section 8.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture with respect to the Securities of such series and under the Securities of such series shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money or Government Obligations in accordance with Section 8.01; provided, however, that if the Company has made any payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or Government Obligations held by the Trustee or the Paying Agent.

ARTICLE IX

SUPPLEMENTAL INDENTURES AND AMENDMENTS

SECTION 9.01. Without Consent of Holders.

The Company and the Trustee may amend or supplement this Indenture or the Securities or waive any provision hereof or thereof without the consent of any Holder:

(1) to cure any ambiguity, omission, defect or inconsistency;

(2) to comply with Section 5.01;

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities, or to provide for the issuance of bearer Securities (with or without coupons);

(4) to provide any security for, or to add any guarantees of or additional obligors on, any series of Securities;

(5) to comply with any requirement in order to effect or maintain the qualification of this Indenture under the TIA;

(6) to add to the covenants of the Company for the benefit of the Holders of all or any series of Securities (and if such covenants are to be for the

49

benefit of less than all series of Securities, stating that such covenants are expressly being included solely for the benefit of such series), or to surrender any right or power herein conferred upon the Company;

(7) to add any additional Events of Default with respect to all or any series of the Securities (and, if any such Event of Default is applicable to less than all series of Securities, specifying the series to which such Event of Default is applicable);

(8) to change or eliminate any of the provisions of this Indenture; provided that any such change or elimination shall become effective only when there is no outstanding Security of any series created prior to the execution of such amendment or supplemental indenture that is adversely affected in any material respect by such change in or elimination of such provision;

(9) to establish the form or terms of Securities of any series as permitted by Section 2.01;

(10) to supplement any of the provisions of this Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of any series of Securities pursuant to Section 8.01; provided, however, that any such action shall not adversely affect the interest of the Holders of Securities of such series or any other series of Securities in any material respect; or

(11) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the Securities of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, pursuant to the requirements of Section 7.08.

Upon the request of the Company, accompanied by a Board Resolution, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with the Company in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be therein contained.

SECTION 9.02. With Consent of Holders.

Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture with the consent (including consents obtained in connection with a tender offer or exchange offer for Securities of any one or more series or all series or a solicitation of consents in respect of Securities of any one or more series or all series, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities of each such series (but the terms of such offer or solicitation may vary from series to series)) of the Holders of at least a majority in principal amount of the then outstanding Securities of all series affected by such amendment or supplement (acting as one class).

50

Upon the request of the Company, accompanied by a Board Resolution, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall, subject to Section 9.06, join with the Company in the execution of such amendment or supplemental indenture.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

The Holders of a majority in principal amount of the then outstanding Securities of one or more series or of all series (acting as one class) may waive compliance in a particular instance by the Company with any provision of this Indenture with respect to Securities of such series (including waivers obtained in connection with a tender offer or exchange offer for Securities of such series or a solicitation of consents in respect of Securities of such series, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities of such series (but the terms of such offer or solicitation may vary from series to series)).

However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not:

(1) reduce the amount of Securities whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the rate of or change the time for payment of interest, including default interest, on any Security;

(3) reduce the principal of, any premium on or any mandatory sinking fund payment with respect to, or change the Stated Maturity of, any Security or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 6.02;

(4) reduce the premium, if any, payable upon the redemption of any Security or change the time at which any Security may or shall be redeemed;

(5) change any obligation of the Company to pay Additional Amounts with respect to any Security;

(6) change the coin or currency or currencies (including composite currencies) in which any Security or any premium, interest or Additional Amounts with respect thereto are payable;

(7) impair the right to institute suit for the enforcement of any payment of principal of, premium (if any) or interest on or any Additional Amounts with respect to any Security pursuant to Sections 6.07 and 6.08, except as limited by Section 6.06;

51

(8) make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of this Indenture pursuant to Section 6.04 or 6.07 or make any change in this sentence of Section 9.02;

(9) waive a continuing Default or Event of Default in the payment of principal of, premium (if any) or interest on or Additional Amounts with respect to the Securities;

(10) if applicable, make any change that materially and adversely affects the right to convert any Security.

A supplemental indenture that changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series.

The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Company in a notice furnished to Holders in accordance with the terms of this Indenture.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

SECTION 9.03. Compliance with the Trust Indenture Act.

Every amendment or supplement to this Indenture or the Securities shall comply in form and substance with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his or her Security or portion of a Security if the Trustee receives written notice of revocation before a date and time therefor identified by the Company in a notice furnished to such Holder in accordance with the terms of this Indenture or, if no such date and time shall be identified, the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

52

The Company may, but shall not be obligated to, fix a record date (which need not comply with TIA § 316(c)) for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver or to take any other action under this Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of Securities required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (1) through (9) of Section 9.02 hereof. In such case, the amendment, supplement or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder’s Security.

SECTION 9.05. Notation on or Exchange of Securities.

If an amendment or supplement changes the terms of an outstanding Security, the Company may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security at the request of the Company regarding the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment or supplement.

Securities of any series authenticated and delivered after the execution of any amendment or supplement may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such amendment or supplement.

SECTION 9.06. Trustee to Sign Amendments, etc.

The Trustee shall sign any amendment or supplement authorized pursuant to this Article if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such amendment or supplement, the Trustee shall be entitled to receive, in addition to the documents required by Section 11.04, and, subject to Section 7.01 hereof, shall be fully protected in relying upon, an Opinion of Counsel provided at the expense of the Company to the effect that such amendment or supplement is authorized or permitted by this Indenture.

Westlake Chemical Corporation

2801 Post Oak Boulevard, Suite 600

Houston, Texas 77056

Ladies and Gentlemen:

We have acted as special counsel to Westlake Chemical Corporation, a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), of the Company’s registration statement on Form S-3 (excluding the documents incorporated by reference therein, the “Registration Statement”) relating to the offering from time to time by the Company, together or separately and in one or more series (if applicable), of (i) debt securities of the Company (the “Debt Securities”); (ii) shares of the Company’s preferred stock, par value $0.01 per share (the “Preferred Stock”); (iii) shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”); and (iv) warrants to purchase debt or equity securities of the Company or other types of securities (the “Warrants”) and the offering from time to time by the selling stockholder named therein (the “Selling Stockholder”) of up to 4,500,000 shares of Common Stock that are issued and outstanding. The Debt Securities, Preferred Stock, Common Stock and Warrants are referred to herein collectively as the “Securities.”

The Securities being registered under the Registration Statement will have an indeterminate aggregate initial offering price and will be offered on a continuous or delayed basis pursuant to the provisions of Rule 415 under the Securities Act.

The Debt Securities may be issued pursuant to an indenture dated as of September 8, 2016 (as amended or supplemented, the “September 2016 Indenture”) between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee, or another indenture that may be entered into between the Company and a trustee (the September 2016 Indenture, and such other indenture or indentures, as amended or supplemented, each, an “Indenture”). The

Cleary Gottlieb Steen & Hamilton LLP or an affiliated entity has an office in each of the cities listed above.

Westlake Chemical Corporation, p. 2

terms of the Preferred Stock are to be established in one or more certificates of designation, rights and preferences filed with the Secretary of State of the State of Delaware (each, a “Certificate of Designation”). The Warrants are to be issued from time to time under one or more warrant agreements to be entered into between the Company and the warrant agent to be named therein (a “Warrant Agreement”).

In arriving at the opinions expressed below, we have reviewed the following documents:

(a) the Registration Statement and the documents incorporated by reference therein;

(b) an executed copy of the September 2016 Indenture, filed as an exhibit to the Registration Statement;

(c) a specimen of the Common Stock; and

(d) copies of the Company’s Amended and Restated Certificate of Incorporation and Amended and Restated By-Laws certified by the Secretary of State of the State of Delaware and the corporate secretary of the Company, respectively.

In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate records of the Company and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinions expressed below.

In rendering the opinions expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that:

1. The Debt Securities will be the valid, binding and enforceable obligations of the Company, entitled to the benefits of the applicable Indenture.

2. The Preferred Stock will be validly issued by the Company, fully paid and nonassessable.

3. The Common Stock that may be issued by the Company, including Common Stock to be issued upon conversion, exchange or exercise of any other Security in accordance with its terms, will be validly issued by the Company, fully paid and nonassessable.

4. The Warrants will be the valid, binding and enforceable obligations of the Company.

5. The shares of Common Stock that may be sold by the Selling Stockholder have been validly issued by the Company and are fully paid and nonassessable.

Insofar as the foregoing opinions relate to the validity, binding effect or enforceability of any agreement or obligation of the Company, (x) we have assumed that the

Westlake Chemical Corporation, p. 3

Company and each other party to such agreement or obligation has satisfied or, prior to the issuance of the Securities, will satisfy those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it and (y) such opinions are subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity.

In rendering the opinions expressed above, we have further assumed that (i) prior to the issuance of the Securities, the Company will authorize the offering and issuance of the Securities and any other Securities issuable on the conversion, exchange or exercise thereof, and will duly authorize, approve and establish the final terms and conditions thereof, which terms will conform to the descriptions thereof in the Registration Statement and the terms of any agreement governing those Securities, and will not violate any applicable law, conflict with any matter of public policy, result in a default under or breach of any agreement or instrument binding upon the Company or violate any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company; (ii) prior to the issuance of the Securities, the Board of Directors of the Company will duly authorize, establish and approve the terms of the Preferred Stock as contemplated by the Company’s Amended and Restated Certificate of Incorporation, the Company will duly authorize, execute and deliver any agreement necessary with respect to the Securities or contemplated by the Securities, any agreement governing the Securities or the Registration Statement, and the Company will take any other appropriate or necessary corporate action, including the filing of any Certificate of Designation with the Secretary of State of the State of Delaware; (iii) the Indenture will conform to the September 2016 Indenture filed as an exhibit to the Registration Statement; (iv) any receipts evidencing Warrants and any agreement governing those Securities will be governed by New York law; (v) the Securities will be offered, issued, sold and delivered in compliance with applicable law and any requirements therefor set forth in any corporate action authorizing such Securities and any agreement governing those Securities and in the manner contemplated by the Registration Statement and the related prospectus describing the Securities and the offering thereof; (vi) the Securities will be offered, sold and delivered to, and paid for by, the purchasers thereof at the price specified in, and in accordance with the terms of, an agreement or agreements duly authorized, executed and delivered by the parties thereto, which price, in the case of Common Stock or Preferred Stock, shall not be less than the respective par value thereof; and (vii) if issued in certificated form, certificates representing the Securities will be duly executed and delivered and, to the extent required by any applicable agreement, duly authenticated and countersigned, and if issued in book-entry form, the Securities will be duly registered to the extent required by any applicable agreement.

In rendering the opinion expressed in paragraph 1 above, we have assumed that each series of Debt Securities will be issued with an original aggregate principal amount (or in the case of Debt Securities issued at original issue discount, an aggregate issue price) of $2,500,000 or more.

We note that any designation in the Securities or any applicable agreement governing those Securities of the U.S. federal courts sitting in New York City as the venue for actions or proceedings relating to such Securities is (notwithstanding any waiver thereof) subject to the power of such courts to transfer actions pursuant to 28 U.S.C. §1404(a) or to dismiss such actions or proceedings on the grounds that such a federal court is an inconvenient forum for such an action or proceeding.

Westlake Chemical Corporation, p. 4

We note that by statute New York provides that a judgment or decree rendered in a currency other than the currency of the United States will be converted into U.S. dollars at the rate of exchange prevailing on the date of entry of the judgment or decree. There is no corresponding federal statute and no controlling Federal court decision on this issue. Accordingly, we express no opinion as to whether a Federal court would award a judgment in a currency other than U.S. dollars or, if it did so, whether it would order conversion of the judgment into U.S. dollars. In addition, to the extent that any Securities or applicable agreement governing those Securities includes a provision relating to indemnification against any loss in obtaining currency due from a court judgment in another currency, we express no opinion as to the enforceability of such provision.

The foregoing opinions are limited to the law of the State of New York and the General Corporation Law of the State of Delaware.

We hereby consent to the use of our name in the prospectus constituting a part of the Registration Statement under the heading “Legal Opinions” and in any prospectus supplements related thereto, as counsel for the Company that has passed on the validity of the Securities, and to the use of this opinion as a part (Exhibit 5.1) of the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission thereunder. The opinions expressed herein are rendered on and as of the date hereof, and we assume no obligation to advise you, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinions expressed herein.

Very truly yours,
CLEARY GOTTLIEB STEEN & HAMILTON LLP
