PROSPECTUS SUPPLEMENT

CELANESE US HOLDINGS LLC

4.625% Senior Notes due 2022

Celanese US Holdings LLC (the Issuer) is offering $500,000,000 aggregate principal amount of its 4.625% Senior Notes due 2022. The notes will bear interest at a rate of 4.625% per annum. Interest on the notes will be payable semi-annually, in cash in arrears, on March 15 and September 15 of each year, commencing March 15, 2013. The notes will mature on November 15, 2022.

The notes will be guaranteed on a senior basis by Celanese Corporation, the Issuer’s parent company (the Parent Guarantor), and each of the Issuer’s current and future domestic subsidiaries that guarantee the Issuer’s obligations under its senior secured credit facilities (the Subsidiary Guarantors, and collectively with the Parent Guarantor, the Guarantors).

The notes and the guarantees will be the Issuer’s and the Guarantors’ general unsecured senior obligations. The notes and the guarantees will be effectively subordinated to the Issuer’s and the Guarantors’ secured debt to the extent of the value of the assets securing such debt. The notes and the guarantees will rank equally in right of payment with all of the Issuer’s and the Guarantors’ existing and future unsecured senior debt and senior in right of payment to any of the Issuer’s future debt that is expressly subordinated in right of payment to the notes and guarantees. The notes and the guarantees will be structurally subordinated to all of the existing and future liabilities, including trade payables, and preferred stock of the Parent Guarantor’s subsidiaries that do not guarantee the notes. See “Description of the Notes—Ranking.”

We may redeem some or all of the notes at a redemption price of 100% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus a “make-whole” premium.

Currently, there is no existing public market for the notes. We do not intend to list the notes on any securities exchange or quotation system.

Investing in the notes involves risks. See “Risk Factors” beginning on page S-8 and in our Annual Report on Form 10-K for the year ended December 31, 2011 and subsequent periodic filings with the SEC.

ABOUT THIS PROSPECTUS SUPPLEMENT

This document has two parts. The first part consists of this prospectus supplement, which describes the specific terms of this offering and the notes offered. The second part, the accompanying prospectus, provides more general information about securities that we may offer, some of which does not apply to this offering. If the description of the offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information in this prospectus supplement.

Before purchasing any notes, you should carefully read both this prospectus supplement and the accompanying prospectus, together with the additional information described under the heading “Incorporation by Reference” herein.

No person is authorized to give any information or to make any representations other than those contained or incorporated by reference in this prospectus supplement and the accompanying prospectus and, if given or made, such information or representations must not be relied upon as having been authorized. This prospectus supplement and the accompanying prospectus do not constitute an offer to sell or the solicitation of an offer to buy any securities other than the securities described in this prospectus supplement or an offer to sell or the solicitation of an offer to buy such securities in any circumstances in which such offer or solicitation is unlawful. Neither the delivery of this prospectus supplement and the accompanying prospectus, nor any sale made hereunder, shall under any circumstances create any implication that there has been no change in our affairs since the date of this prospectus supplement, or that the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus is correct as of any time subsequent to the date of such information. The distribution of this prospectus supplement and the accompanying prospectus and the offering of the notes in certain jurisdictions may be restricted by law.

This prospectus supplement and the accompanying prospectus do not constitute an offer, or an invitation on our behalf or the underwriters or any one of them, to subscribe to or purchase any of the notes, and may not be used for or in connection with an offer or solicitation by anyone, in any jurisdiction in which such an offer or solicitation is not authorized or to any person to whom it is unlawful to make such an offer or solicitation. See “Underwriting.”

As used throughout this prospectus supplement, unless the context otherwise requires or indicates:

• “Celanese” means Celanese Corporation, and not its subsidiaries;

• “Celanese US” and “Issuer” mean Celanese US Holdings LLC, a wholly-owned subsidiary of Celanese, and not its subsidiaries; and

• “Company” “we,” “our,” and “us” refer to Celanese and its subsidiaries, including Celanese US, on a consolidated basis.

Terms capitalized but not defined in this prospectus supplement shall have the meaning ascribed to them in the accompanying prospectus.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain parts of this prospectus supplement and the accompanying prospectus, and the documents incorporated by reference contain forward-looking statements, as defined in Section 27A of the Securities Act of 1933, as amended (Securities Act), Section 21E of the Securities Exchange Act of 1934, as amended (Exchange Act), and the Private Securities Litigation Reform Act of 1995. You can identify these statements by the fact that they do not relate to matters of a strictly factual or historical nature and generally discuss or relate to forecasts, estimates or other expectations regarding future events. Generally, words such as “anticipate,” “believe,”

S-1

“estimate,” “expect,” “intend,” “plan,” “project,” “may,” “can,” “could,” “might,” “will” and similar expressions, as they relate to us, are intended to identify forward-looking statements. These statements reflect our current views and beliefs with respect to future events at the time that the statements are made, are not historical facts or guarantees of future performance and are subject to significant risks, uncertainties and other factors that are difficult to predict and many of which are outside of our control. Further, certain forward-looking statements are based upon assumptions as to future events that may not prove to be accurate and, accordingly, should not have undue reliance placed upon them.

The following factors could cause our actual results to differ materially from those results, performance or achievements that may be expressed or implied by such forward-looking statements. These factors include, among other things:

• changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate;

• the length and depth of product and industry business cycles particularly in the automotive, electrical, textiles, electronics and construction industries;

• changes in the price and availability of raw materials, particularly changes in the demand for, supply of, and market prices of ethylene, methanol, natural gas, wood pulp and fuel oil and the prices for electricity and other energy sources;

• the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases;

• the ability to maintain plant utilization rates and to implement planned capacity additions and expansions;

• the ability to reduce or maintain at their current levels production costs and improve productivity by implementing technological improvements to existing plants;

• increased price competition and the introduction of competing products by other companies;

• changes in the degree of intellectual property and other legal protection afforded to our products or technologies, or the theft of such intellectual property;

• costs and potential disruption or interruption of production or operations due to accidents, cyber security incidents, terrorism or political unrest, or other unforeseen events or delays in construction of facilities;

• potential liability for remedial actions and increased costs under existing or future environmental regulations, including those relating to climate change;

• potential liability resulting from pending or future litigation, or from changes in the laws, regulations or policies of governments or other governmental activities in the countries in which we operate;

• changes in currency exchange rates and interest rates;

• our level of indebtedness, which could diminish our ability to raise additional capital to fund operations or limit our ability to react to changes in the economy or the chemicals industry; and

• various other factors, both referenced and not referenced in this prospectus supplement or the accompanying prospectus.

Additional information regarding these and other factors may be contained in our filings with the Securities and Exchange Commission (SEC) incorporated by reference in the prospectus, especially on Forms 10-K, 10-Q and 8-K. See “Incorporation by Reference” herein. Many of these factors are macroeconomic in nature and are, therefore, beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results, performance or achievements may vary materially

S-2

from those described in this prospectus supplement and the accompanying prospectus as anticipated, believed, estimated, expected, intended, planned or projected. Except as required by law, we neither intend nor undertake any obligation, and disclaim any duty, to update these forward-looking statements, which speak only as of their respective dates.

S-6

Certain Covenants	The indenture governing the notes contains covenants that limit, among other things, the Issuer’s ability and the ability of its restricted subsidiaries to:

S-7

RISK FACTORS

Investing in the notes involves various risks, including the risks described below as well as those discussed under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011 and subsequent filings with the SEC. You should carefully consider these risks and the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus before investing in the notes. These risks are not the only ones we face. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations, financial condition and results of operations. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The trading price of the notes could decline due to any of these risks, and you may lose all or part of your investment.

Risks Relating to the Notes and the Guarantees

Our level of indebtedness could diminish our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or the chemicals industry and prevent us from meeting obligations under our indebtedness.

As of September 30, 2012, our total indebtedness was approximately $3.0 billion. In addition, as of September 30, 2012 we had $158 million available for borrowing under our credit-linked revolving facility and $600 million available under our revolving credit facility.

Our level of indebtedness could have important consequences, including:

• increasing our vulnerability to general economic and industry conditions including exacerbating any adverse business effects that are determined to be material adverse effects for purposes of our senior credit facilities;

• requiring a substantial portion of our cash flow from operations to be dedicated to the payment of principal and interest on indebtedness, therefore reducing our ability to use our cash flow to fund operations, capital expenditures and future business opportunities or pay dividends on our common stock;

• exposing us to the risk of increased interest rates as certain of our borrowings are at variable rates of interest;

• limiting our ability to obtain additional financing for working capital, capital expenditures, product development, debt service requirements, acquisitions and general corporate or other purposes; and

• limiting our ability to adjust to changing market conditions and placing us at a competitive disadvantage compared to our competitors who have less debt.

We may be able to incur additional indebtedness in the future, which could increase the risks described above.

Although covenants under our senior credit facilities and the indentures governing the Issuer’s outstanding 6.625% Senior Notes due 2018 and 5.875% Senior Notes due 2021 (collectively, the Outstanding Notes) limit, and the indenture governing the notes will limit, our ability to incur certain additional indebtedness, these restrictions are subject to a number of qualifications and exceptions, and the indebtedness we could incur in compliance with these restrictions could be significant. To the extent that we incur additional indebtedness, the risks associated with our leverage described above, including our possible inability to service our debt, including the notes, would increase.

S-8

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly and affect our operating results.

Certain of our borrowings are at variable rates of interest and expose us to interest rate risk. If interest rates were to increase, our debt service obligations on our variable rate indebtedness would increase. As of September 30, 2012, we had $1.1 billion, €210 million and CNY 999 million of variable rate debt, of which $1.1 billion was hedged with an interest rate swap maturing January 2, 2014, leaving $31 million, €210 million and CNY 999 million of variable rate debt subject to interest rate exposure. Accordingly, a 1% increase in interest rates would increase annual interest expense by approximately $5 million.

We may not be able to generate sufficient cash to service our indebtedness, and may be forced to take other actions to satisfy obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on or to refinance our debt obligations depends on the financial condition and operating performance of our subsidiaries, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, including the notes.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital or restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Certain covenants in our senior credit facilities and the indentures governing the Outstanding Notes restrict, and the indenture governing the notes will restrict, our ability to dispose of assets and use the proceeds from the disposition. We may not be able to consummate those dispositions or to obtain the proceeds which we could realize from them and these proceeds may not be adequate to meet any debt service obligations then due.

Restrictive covenants in our senior credit facilities and the indentures governing the Outstanding Notes and the notes may limit our ability to engage in certain transactions and may diminish our ability to make payments on our indebtedness.

Our senior credit facilities and the indentures governing the Outstanding Notes each contain, and the indenture governing the notes will contain, various covenants that limit our ability to engage in specified types of transactions. The indentures governing the Outstanding Notes limit, and the indenture governing the notes will limit, the Issuer’s and certain of its subsidiaries’ ability to, among other things, incur additional debt; pay dividends or make other restricted payments; consummate specified asset sales; enter into transactions with affiliates; incur liens, impose restrictions on the ability of a subsidiary to pay dividends or make payments to the Issuer and its restricted subsidiaries; merge or consolidate with any other person; and sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the Issuer’s assets or the assets of its restricted subsidiaries. See “Description of the Notes—Certain Covenants.”

In addition, our senior credit facilities require us to maintain a maximum first lien senior secured leverage ratio if there are outstanding borrowings under the revolving credit facility. Our ability to meet this financial ratio can be affected by events beyond our control, and we may not be able to meet this test at all.

Such restrictions in our debt instruments could cause us to require the consent of holders of the Outstanding Notes and the notes and of our lenders in order to take certain actions. Disruptions in credit markets may prevent us from obtaining or make it more difficult or more costly for us to obtain such consents. Our ability to expand our business or to address declines in our business may be limited if we are unable to obtain such consents.

S-9

A breach of any of these covenants could result in a default, which, if not cured or waived, could have a material adverse effect on our business, financial condition and results of operations. Furthermore, a default under our senior credit facilities could permit lenders to accelerate the maturity of our indebtedness under our senior credit facilities and to terminate any commitments to lend. If we were unable to repay such indebtedness, the lenders under our senior credit facilities could proceed against the collateral granted to them to secure that indebtedness. Our subsidiaries have pledged a significant portion of our assets as collateral to secure our indebtedness under our senior credit facilities. If the lenders under our senior credit facilities accelerate the repayment of such indebtedness, we may not have sufficient assets to repay such amounts or our other indebtedness, including the notes. In such event, we could be forced into bankruptcy or liquidation and, as a result, you could lose your investment in the notes.

The Issuer and Celanese are holding companies and depend on subsidiaries to satisfy their obligations under the notes and the guarantee of the Issuer’s obligations under the notes by Celanese.

As holding companies, the Issuer and Celanese, which we refer to as the Parent Guarantor, conduct substantially all of their operations through their subsidiaries, which own substantially all of our consolidated assets. Consequently, the principal source of cash to pay the Issuer’s and Parent Guarantor’s obligations, including obligations under the notes and the guarantee of the Issuer’s obligations under the notes by the Parent Guarantor, is the cash that our subsidiaries generate from their operations. We cannot assure you that our subsidiaries will be able to, or be permitted to, make distributions to enable the Issuer or the Parent Guarantor to make payments in respect of their obligations. Each of our subsidiaries is a distinct legal entity and, under certain circumstances, applicable state laws, regulatory limitations and terms of our debt instruments may limit the Issuer’s and the Parent Guarantor’s ability to obtain cash from our subsidiaries. While the indenture governing the notes limits the ability of our subsidiaries to restrict their ability to pay dividends or make other intercompany payments to us, these limitations are subject to certain qualifications and exceptions, which may have the effect of significantly restricting the applicability of those limits. In the event the Issuer and the Parent Guarantor do not receive distributions from our subsidiaries, the Issuer and the Parent Guarantor may be unable to make required payments on the notes, the guarantee of the Issuer’s obligations under the notes by the Parent Guarantor, or our other indebtedness.

Many of the covenants in the indenture governing the notes will cease to apply from and after the first date when the notes are rated investment grade by Moody’s and Standard & Poor’s, provided no default has occurred and is continuing.

Many of the covenants contained in the indenture governing the notes will cease to apply from and after the first date when the notes receive an investment grade rating from Moody’s and Standard & Poor’s, provided no default has occurred and is then continuing. There can be no assurance that the notes, if they are rated investment grade, will maintain such ratings. Termination of these covenants will allow us to engage in certain actions that would not have been permitted were these covenants in force. Upon termination, these covenants will no longer apply even if the notes are subsequently downgraded below investment grade. See “Description of the Notes—Termination of Covenants.”

Federal and state statutes could allow courts, under specific circumstances, to void or subordinate the notes or any of the subsidiary guarantees and require note holders to return payments received from the Issuer or the Subsidiary Guarantors.

Under federal bankruptcy law and comparable provisions of state fraudulent transfer laws, the notes or any of the guarantees thereof by the subsidiaries of Celanese, which we refer to as the Subsidiary Guarantors, could be voided, or claims in respect of the notes or any of the guarantees thereof by the Subsidiary Guarantors could

S-10

be subordinated to all of the Issuer’s indebtedness or that of the Subsidiary Guarantors if, among other things, the Issuer or a Subsidiary Guarantor, at the time the Issuer or such Subsidiary Guarantor incurred the indebtedness evidenced by the notes or such guarantee:

• received less than reasonably equivalent value or fair consideration for the issuance of the notes or for the incurrence of such guarantee; and

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

• were engaged in a business or transaction for which the Issuer’s or the Subsidiary Guarantor’s remaining assets constituted unreasonably small capital; or

• intended to incur, or believed that the Issuer or the Subsidiary Guarantor would incur, debts beyond the Issuer’s or the Subsidiary Guarantor’s ability to pay such debts as they mature; or

• the Issuer or any of the Subsidiary Guarantors was a defendant in an action for money damages docketed against the Issuer or such Subsidiary Guarantor if, in either case, after final judgment, the judgment was unsatisfied.

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or an antecedent debt is secured or satisfied. A bankruptcy court could also void the notes or a guarantee if it found that the Issuer or the Subsidiary Guarantors issued the notes or the guarantees with the actual intent to hinder, delay or defraud creditors.

We cannot be certain as to the standards a court would use to determine whether or not the Issuer or the Subsidiary Guarantors were solvent at the relevant time or, regardless of the standard that a court uses, whether the notes or the guarantees would be subordinated to the Issuer’s or any of the Subsidiary Guarantors’ other debt. In general, however, a court would deem an entity insolvent if:

• the sum of its debts, including contingent and unliquidated liabilities, was greater than the fair saleable value of all of its assets;

• the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or

• it could not pay its debts as they became due.

If a court were to void the issuance of the notes or the incurrence of the guarantees as the result of a fraudulent transfer or conveyance, or hold such obligations unenforceable for any other reason, holders of the notes would cease to have a claim against the Issuer or that Subsidiary Guarantor on its guarantee. A court could also subordinate the notes or any of the guarantees to the other indebtedness of the Issuer or the applicable Subsidiary Guarantor, direct that holders of the notes return any amounts paid under the notes or a guarantee to the Issuer or the applicable Subsidiary Guarantor or to a fund for the benefit of its creditors, or take other action detrimental to the holders of the notes.

Each guarantee will contain a provision intended to limit the Subsidiary Guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its guarantee to be a fraudulent transfer. Each Subsidiary Guarantor that makes a payment or distribution under a guarantee will be entitled to a contribution from each other Subsidiary Guarantor in an amount pro rata, based on the net assets of each Subsidiary Guarantor. Under recent case law, these provisions may not be effective to protect the guarantees from being voided under fraudulent transfer or conveyance law.

S-11

We cannot assure you that an active trading market for the notes will exist if you desire to sell the notes.

There is no existing public market for the notes. We do not intend to have the notes listed on a national securities exchange or to arrange for quotation on any automated dealer quotation systems. Therefore, we cannot assure you as to the development or liquidity of any trading market for the notes. The liquidity of any market for the notes will depend on a number of factors, including:

• the number of holders of notes;

• our operating performance and financial condition;

• the market for similar securities;

• the interest of securities dealers in making a market in the notes; and

• prevailing interest rates.

Historically, the market for non-investment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. The market, if any, for the notes may face similar disruptions that may adversely affect the prices at which you could sell your notes. Therefore, you may not be able to sell your notes at a particular time and the price that you receive when you sell may not be favorable.

We may be unable to purchase the notes upon a change of control event.

Upon a change of control event, as defined in the indentures governing the Outstanding Notes and the notes, the Issuer is required to offer to purchase all of the Outstanding Notes and the notes then outstanding for cash at 101% of the principal amount thereof plus accrued and unpaid interest, if any. Similarly, the occurrence of a change of control could create an event of default under our senior credit facilities, permitting the lenders to accelerate the maturity of the indebtedness under our senior credit facilities and terminate their commitments to lend under our revolving credit facility. Our other indebtedness also may contain repayment requirements with respect to specific events that constitute a change of control. If a change of control event occurs, we may not have sufficient funds to pay the change of control purchase price with respect to the Outstanding Notes or the notes or to repay outstanding indebtedness under our senior credit facilities or our other indebtedness, and may be required to secure new third party financing to do so. We may not be able to obtain this financing on commercially reasonable terms, or on terms acceptable to us, or at all. Our failure to repurchase the notes upon a change of control event would constitute an event of default under the indenture.

The change of control event provisions in the indenture governing the notes may not protect you in the event we consummate a highly leveraged transaction, reorganization, restructuring, merger or other similar transaction, unless such transaction constitutes a change of control event under the indenture. Such a transaction may not involve a change in voting power or beneficial ownership or, even if it does, may not involve a change in the magnitude required under the definition of change of control in the indenture to trigger our obligation to repurchase the notes. Except as otherwise described above, the indenture does not contain provisions that permit the holders of the notes to require the Issuer to repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction. See “Description of the Notes—Repurchase at the Option of Holders—Change of Control Event.”

Your right to receive payments on the notes will be effectively subordinated to the right of lenders who have a security interest in our assets, to the extent of the value of those assets.

Subject to the restrictions in the indentures governing the Outstanding Notes and the notes, we, including our subsidiaries, may incur significant additional indebtedness secured by assets. If we are declared bankrupt or insolvent, or if we default under any of our existing or future indebtedness secured by assets, the holders of such

S-12

indebtedness could declare all of the funds borrowed thereunder, together with accrued interest, immediately due and payable. If we were unable to repay such indebtedness, the holders of such indebtedness could, to the extent of such indebtedness, foreclose on such assets to the exclusion of holders of the notes. In any such event, because the notes will not be secured by our assets, remaining proceeds, if any, from the sale of such assets will be available to pay obligations on the notes only after such indebtedness has been paid in full.

The notes will be structurally subordinated to all indebtedness of our current subsidiaries that are not, and any of our future subsidiaries that do not become, guarantors of the notes.

The notes will, subject to certain exceptions, be guaranteed by those of our domestic subsidiaries that guarantee our senior credit facilities. Each of our current subsidiaries that is not, and any future subsidiary that does not become, a Subsidiary Guarantor under our senior credit facilities, and therefore under the notes, will have no obligation, contingent or otherwise, to pay amounts due under the notes or to make any funds available to pay those amounts, whether by dividend, distribution, loan or other payment. The notes will be structurally subordinated to all indebtedness and other obligations of any non-guarantor subsidiary such that, in the event of insolvency, liquidation, reorganization, dissolution or other winding up of any subsidiary that is not a guarantor of the notes, all of such subsidiary’s creditors (including trade creditors and preferred stockholders, if any) would be entitled to payment in full out of such subsidiary’s assets before we (and therefore the holders of the notes) would be entitled to any payment.

You must rely on the procedures and the relevant clearing systems to exercise your rights and remedies.

Owners of book-entry interests will not be considered owners or holders of notes. Instead, The Depository Trust Company (DTC) or its nominee will be the sole holder of the notes. Payments of principal, interest and other amounts owing on or in respect of the notes in global form will be made to the paying agent, which will make payments to DTC. Thereafter, those payments will be credited to DTC participants’ accounts that hold book-entry interests in the notes in global form and credited by such participants to indirect participants. Unlike holders of certificated notes, owners of book-entry interests do not have the direct right to act upon our solicitations for consents or requests for waivers or other actions from holders of the notes. Instead, you will be permitted to act only to the extent you have received appropriate proxies to do so from DTC or, if applicable, a participant. Procedures implemented for the granting of such proxies may not be sufficient to enable you to vote on any requested actions on a timely basis.

USE OF PROCEEDS

We estimate that the net proceeds from this offering of the notes will be approximately $490 million after deducting underwriting discounts and commissions and other estimated fees and expenses of this offering. We intend to use the net proceeds from this offering, together with cash on hand, to repay $400 million of the outstanding term loans under our senior credit facilities, which term loans currently bear interest at LIBOR plus a margin of 2.75% and mature October 31, 2016, and to make a cash contribution of $100 million to the Celanese Americas Retirement Pension Plan. Affiliates of certain of the underwriters are lenders under our senior credit facilities and may receive a portion of the net proceeds from this offering.

DESCRIPTION OF THE NOTES

You can find the definitions of certain terms used in this description under the subheading “—Certain Definitions.” In this description, the term “Issuer” refers only to Celanese US Holdings LLC, and not to any of its subsidiaries.

The notes will be issued under a base indenture, dated as of May 6, 2011, by and among the Issuer, the Guarantors and Wells Fargo Bank, National Association, as trustee (the Trustee), as supplemented by a second supplemental indenture to be dated as of the closing date of this offering by and among the Issuer, the Guarantors and the Trustee. As used in this section, all references to the “indenture” mean the base indenture as supplemented by the second supplemental indenture. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939.

The following description is a summary of the material provisions of the indenture. It does not restate the indenture in its entirety. We urge you to read the indenture because it, and not this description, defines the rights of holders of the notes. A copy of the base indenture is available as set forth under “Incorporation by Reference”, and a copy of the second supplemental indenture will be filed on a current report on Form 8-K and available as set forth under “Incorporation by Reference”. Certain defined terms used in this description but not defined below under “—Certain Definitions” have the meanings assigned to them in the indenture.

The registered holder of any note will be treated as the owner of it for all purposes. Only registered holders will have rights under the indenture.

Principal, Maturity and Interest

The Issuer will issue $500,000,000 aggregate principal amount of notes in this offering. The notes will mature on November 15, 2022. The indenture governing the notes will provide for the issuance of additional notes of the same class and series, subject to compliance with the covenants contained in the indenture. The notes will be issued in denominations of $1,000 and integral multiples of $1,000 in excess thereof.

Interest on the notes will accrue at the rate of 4.625% per annum and will be payable semi-annually in arrears on March 15 and September 15, commencing on March 15, 2013. The Issuer will make each interest payment to the holders of record of the notes on the immediately preceding March 1 and September 1.

Interest on the notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Payments on the Notes

Principal of, premium, if any, and interest on the notes will be payable at the office or agency maintained by the Issuer for such purposes or, at the option of the Issuer, payment of interest may be made by check mailed to the holders of the notes at their respective addresses set forth in the register of holders;provided that all payments of principal, premium, if any, and interest with respect to the notes represented by one or more global notes registered in the name of or held by DTC or its nominee will be made through the facilities of DTC. Until otherwise designated by the Issuer, the Issuer’s office or agency will be the office of the Trustee maintained for such purpose.

Paying Agent and Registrar for the Notes

The Trustee will initially act as paying agent and registrar. The Issuer may change the paying agent or registrar without prior notice to the holders, and the Issuer or any of its Subsidiaries may act as paying agent or registrar.

S-17

Transfer and Exchange

A holder may transfer or exchange notes in accordance with the indenture. The registrar and the Trustee may require a holder to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders will be required to pay all taxes due on transfer. The Issuer is not required to transfer or exchange any note selected for redemption or repurchase. Also, the Issuer is not required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed or repurchased.

Guarantees

The notes will be guaranteed by the Parent Guarantor and each direct and indirect Restricted Subsidiary that guarantees the Issuer’s obligations under the Credit Agreement. The Guarantors will jointly and severally guarantee the Issuer’s obligations under the indenture and the notes on a senior unsecured, full and unconditional basis. The obligations of each Guarantor (other than a company that is a direct or indirect parent of the Issuer) under its Guarantee will be limited as necessary to prevent the Guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law. By virtue of this limitation, a Guarantor’s obligation under its Guarantee could be significantly less than amounts payable with respect to the notes, or a Guarantor may have effectively no obligation under its Guarantee. See “Risk Factors—Risks Related to the Notes and the Guarantees—Federal and state statutes could allow courts, under specific circumstances, to void or subordinate the notes or any of the subsidiary guarantees and require note holders to return payments received from the Issuer or the Subsidiary Guarantors.” In an effort to alleviate the effect of this limitation, each Guarantor that makes a payment or distribution under a Guarantee will be entitled to a contribution from each other Guarantor (if any) in an amount pro rata, based on the net assets of each Guarantor.

Each Guarantor may consolidate with or merge into or sell its assets to the Issuer or another Guarantor without limitation, or with, into or to any other Person upon the terms and conditions set forth in the indenture. See “—Certain Covenants—Merger, Consolidation or Sale of Assets.”

A Guarantor (other than a company that is a direct or indirect parent of the Issuer except in the case of clause (a)(ii) or (v) below) shall be automatically and unconditionally released and discharged from all of its obligations under its Guarantee of the notes if:

(a) (i) all of its assets or Capital Stock is sold or transferred, in each case in a transaction in compliance with the covenant described under “—Repurchase at the Option of Holders—Asset Sales,” (ii) the Guarantor merges with or into, or consolidates with or amalgamates with, or transfers all or substantially all of its assets to, another Person in compliance with the covenant described under “—Certain Covenants—Merger, Consolidation or Sale of Assets,” (iii) such Guarantor is designated an Unrestricted Subsidiary in accordance with the terms of the indenture, (iv) in connection with any (direct or indirect) sale of Capital Stock or other transaction that results in the Subsidiary Guarantor ceasing to be a Subsidiary of the Issuer, if the sale or other transaction complies with the provisions of the covenant described under “—Repurchase at the Option of Holders—Asset Sales;” or (v) upon legal defeasance of the notes or satisfaction and discharge of the indenture as provided below under the captions “—Legal Defeasance and Covenant Defeasance” and “—Satisfaction and Discharge;”

(b) such Guarantor has delivered to the Trustee a certificate of a Responsible Officer and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to such transaction have been complied with; and

(c) such Guarantor is released from its guarantee of the Credit Agreement.

S-18

Ranking

Senior Debt

The notes will be general unsecured obligations of the Issuer that rank senior in right of payment to all existing and future Indebtedness that is expressly subordinated in right of payment to the notes. The notes will rank equally in right of payment with all existing and future liabilities of the Issuer that are not so subordinated and will be effectively subordinated to all of the Issuer’s Secured Debt (to the extent of the value of the assets securing such Indebtedness) and liabilities of our Subsidiaries that do not guarantee the notes. In the event of bankruptcy, liquidation, reorganization or other winding up of the Issuer or the Guarantors or upon a default in payment with respect to, or the acceleration of, any Indebtedness under the Credit Agreement or other senior secured Indebtedness, the assets of the Issuer and the Guarantors that secure such senior secured Indebtedness will be available to pay obligations on the notes and the Guarantees only after all Indebtedness under such Credit Agreement and other senior secured Indebtedness has been repaid in full from such assets. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all the notes and the Guarantees then outstanding.

Liabilities of Subsidiaries versus Notes

Some of the Subsidiaries of the Issuer will not guarantee the notes, and, as described above under “—Guarantees,” Guarantees of Subsidiaries may be released under certain circumstances. In addition, future Subsidiaries of the Issuer may not be required to guarantee the notes. Claims of creditors of any Subsidiaries that are not Guarantors, including trade creditors and creditors holding indebtedness or guarantees issued by such Subsidiaries, and claims of preferred stockholders of such Subsidiaries generally will have priority with respect to the assets and earnings of such Subsidiaries over the claims of creditors of the Issuer, including holders of the notes. Accordingly, the notes and each Guarantee will be effectively subordinated to creditors (including trade creditors) and preferred stockholders, if any, of such Subsidiaries that are not Guarantors.

As of September 30, 2012:

• the Issuer’s non-guarantor Subsidiaries collectively held $6,575 million in assets; and

• the Issuer’s non-guarantor Subsidiaries had $4,261 million of liabilities, including trade payables.

Although the indenture limits the incurrence of Indebtedness and preferred stock by the Issuer and certain of its Subsidiaries, such limitation is subject to a number of significant qualifications. Moreover, the indenture does not impose any limitation on the incurrence by such Subsidiaries of liabilities that are not considered Indebtedness under the indenture. See “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.”

Optional Redemption

The notes may be redeemed, in whole or in part, at the option of the Issuer upon not less than 30 nor more than 60 days’ prior notice sent to each holder’s registered address, at a redemption price equal to 100% of the principal amount of the notes redeemedplus the Applicable Premium as of, and accrued and unpaid interest to the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

In addition, the Issuer may acquire notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the indenture.

S-19

Mandatory Redemption

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the notes.

Repurchase at the Option of Holders

Change of Control Event

If a Change of Control Event occurs, each holder of notes will have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of that holder’s notes pursuant to a Change of Control Offer on the terms set forth in the indenture. In the Change of Control Offer, the Issuer will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest on the notes repurchased, to the date of purchase. Within 30 days following any Change of Control Event, the Issuer will send a notice to each holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent, pursuant to the procedures required by the indenture and described in such notice. The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the indenture by virtue of such conflict.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(1) accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and

(3) deliver or cause to be delivered to the Trustee the notes properly accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being purchased by the Issuer.

The paying agent will promptly mail to each holder of notes properly tendered the Change of Control Payment for such notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any;provided that each new note will be in a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof.

The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control Event will be applicable whether or not any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control Event, the indenture contains no provisions that permit the holders of the notes to require that the Issuer repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

The Issuer will not be required to make a Change of Control Offer upon a Change of Control Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by the Issuer and purchases all notes properly tendered and not withdrawn under the Change of Control Offer or (2) notice of redemption has been given pursuant to the indenture as described above under the caption “—Optional Redemption,” unless and

S-20

until there is a default in the payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control Event or conditional upon the occurrence of a Change of Control Event, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made and such Change of Control Offer is otherwise made in compliance with the provisions of this covenant.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of the Issuer and its Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require the Issuer to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Issuer and its Subsidiaries taken as a whole to another Person or group may be uncertain.

Also see “Risk Factors—Risks Related to the Notes and the Guarantees—We may be unable to purchase the notes upon a change of control event.”

Asset Sales

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Issuer (or such Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in the Asset Sale by the Issuer or such Restricted Subsidiary is in the form of cash or Cash Equivalents.

For purposes of clause (2) above and for no other purpose, the amount of (i) any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto) of the Issuer or any Restricted Subsidiary (other than liabilities that are by their terms subordinated to the notes or the Guarantees) that are assumed by the transferee of any such assets, (ii) any securities received by the Issuer or such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the receipt thereof, (iii) the fair market value (as determined in good faith by the Issuer) of (A) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (B) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or any Restricted Subsidiary or (C) a combination of (A) and (B), and (iv) any Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value (as determined in good faith by the Issuer), taken together with all other Designated Non-cash Consideration received pursuant to this clause (iv) that is at that time outstanding, not to exceed 5.0% of Total Assets at the time of the receipt of such Designated Non-cash Consideration (with the fair market value of each item of Designated Non-cash Consideration being measured at the time received without giving effect to subsequent changes in value) shall be deemed to be cash.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Issuer may apply those Net Proceeds at its option to:

(1) permanently reduce Obligations under Secured Debt of the Issuer or a Guarantor (and to correspondingly reduce commitments with respect thereto) or Indebtedness of a Restricted Subsidiary that is not a Guarantor, in each case other than Indebtedness owed to the Issuer or a Subsidiary of the Issuer;

S-21

(2) make an investment in (A) any one or more businesses;provided that such investment in any business is in the form of the acquisition of Capital Stock and results in the Issuer or a Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (B) capital expenditures or (C) other assets, in each of (A), (B) and (C), used or useful in a Permitted Business; and/or

(3) make an investment in (A) any one or more businesses;provided that such investment in any business is in the form of the acquisition of Capital Stock and it results in the Issuer or a Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (B) properties or (C) assets that, in each of (A), (B) and (C), replace the businesses, properties and assets that are the subject of such Asset Sale.

Any Net Proceeds from an Asset Sale not applied or invested in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Proceeds shall constitute “Excess Proceeds,”provided that if during such 365-day period the Issuer or a Restricted Subsidiary enters into a definitive binding agreement committing it to apply such Net Proceeds in accordance with the requirements of clause (2) or (3) of the immediately preceding paragraph after such 365th day, such 365-day period will be extended with respect to the amount of Net Proceeds so committed for a period not to exceed 180 days until such Net Proceeds are required to be applied in accordance with such agreement (or, if earlier, until termination of such agreement).

When the aggregate amount of Excess Proceeds exceeds $40.0 million, the Issuer or the applicable Restricted Subsidiary will make an offer (an Asset Sale Offer) to all holders of notes and, at the option of the Issuer, Indebtedness that ranks pari passu with the notes and contains provisions similar to those set forth in the indenture with respect to mandatory prepayments, redemptions or offers to purchase with the proceeds of sales of assets, to purchase, on a pro rata basis (or as near a pro rata basis in accordance with the applicable rules and procedures of DTC), the maximum principal amount of notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash.

Pending the final application of any Net Proceeds, the Issuer or such Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by the indenture.

If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer or the applicable Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the notes to be purchased on a pro rata basis (or as near a pro rata basis in accordance with the applicable rules and procedures of DTC). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the indenture by virtue of such conflict.

Selection and Notice

If less than all of the notes under the indenture are to be redeemed at any time, the Trustee will select notes for redemption as follows:

(1) if the notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the notes are listed; or

S-22

(2) if the notes are not listed on any national securities exchange, on a pro rata basis to the extent practicable and in accordance with the applicable rules and procedures of DTC.

However, no notes of $1,000 or less will be redeemed in part. Notices of redemption will be sent at least 30 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the indenture. Notices of redemption may not be conditional.

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. However, no notes of $1,000 or less will be redeemed in part. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of them called for redemption if funds sufficient to pay the redemption price have been deposited with a paying agent.

Termination of Covenants

If at any time after the Issue Date (i) the notes have Investment Grade Ratings from each of S&P and Moody’s (or, if either (or both) of S&P and Moody’s have been substituted in accordance with the definition of Rating Agencies, by each of the then applicable Rating Agencies) and (ii) no Default has occurred and is continuing under the indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a Covenant Termination Event), the Issuer and its Restricted Subsidiaries will not be subject to the covenants in the indenture specifically listed under the following captions in this “Description of the Notes” section of this prospectus supplement (the Terminated Covenants):

(1) “—Repurchase at the Option of Holders—Asset Sales”;

(2) “—Certain Covenants—Restricted Payments”;

(3) “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock”;

(4) “—Certain Covenants—Dividend and Other Payment Restrictions Affecting Subsidiaries”;

(5) clause (4) of the first paragraph of “—Certain Covenants—Merger, Consolidation or Sale of Assets”;

(6) “—Certain Covenants—Transactions with Affiliates”; and

(7) “—Certain Covenants—Business Activities.”

In the event that a Termination Event occurs, the Issuer and its Restricted Subsidiaries will no longer be subject to the Terminated Covenants, regardless of whether and on any subsequent date one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the notes below an Investment Grade Rating.

There can be no assurance that the notes will ever achieve or maintain an Investment Grade Rating from any Rating Agency.

The Issuer will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the second to last sentence of the definition of Unrestricted Subsidiary. For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding investments by the Issuer and the Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the second paragraph of the definition of Investments. Such designation will be permitted only if a Restricted Payment in such amount would be permitted at such time under this covenant or the definition of Permitted Investments and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Unrestricted Subsidiaries will not be subject to any of the restrictive covenants described in this summary.

The indenture will not treat (1) unsecured Indebtedness as subordinated or junior to Indebtedness secured by a Lien merely because it is unsecured or (2) Indebtedness (other than Subordinated Indebtedness) as subordinated or junior to any other such Indebtedness merely because it has a junior priority with respect to the same collateral.

The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Issuer or such Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant will be determined in good faith by the Board of Directors.

As of September 30, 2012, the amount of Restricted Payments permitted to be made pursuant to clause (c) of the first paragraph of this covenant was approximately $734 million.

Incurrence of Indebtedness and Issuance of Preferred Stock

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, incur) any Indebtedness (including Acquired Debt), and the Issuer will not permit any of its Restricted Subsidiaries to issue any shares of Preferred Stock;provided,however, that the Issuer and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) and any Restricted Subsidiary may issue Preferred Stock if the Fixed Charge Coverage Ratio for the Issuer’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Preferred Stock is issued would have been at least 2.00 to 1.00, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Preferred Stock had been issued, as the case may be, and the application of proceeds therefrom had occurred at the beginning of such four-quarter period.

(6) the maximum amount of Indebtedness that the Issuer and its Restricted Subsidiaries may incur pursuant to this covenant shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies.

(1) in the case of any Lien securing an obligation that ranks pari passu with the notes or a Guarantee, effective provision is made to secure the notes or such Guarantee, as the case may be, at least equally and ratably with or prior to such obligation with a Lien on the same assets of the Issuer or such Restricted Subsidiary, as the case may be; and

(2) in the case of any Lien securing Subordinated Indebtedness, effective provision is made to secure the notes or such Guarantee, as the case may be, with a Lien on the same assets of the Issuer or such Restricted Subsidiary, as the case may be, that is prior to the Lien securing such Subordinated Indebtedness.

Dividend and Other Payment Restrictions Affecting Subsidiaries

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any such Restricted Subsidiary to:

(2) make loans or advances to the Issuer or any of its Restricted Subsidiaries; or

(3) sell, lease or transfer any of its properties or assets to the Issuer or any of its Restricted Subsidiaries.

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1) contractual encumbrances or restrictions in effect on the Issue Date, including, without limitation, pursuant to Existing Indebtedness or the Credit Agreement and related documentation;

(2) the indenture, the notes and the Guarantees;

(3) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature discussed in clause (3) above in the first paragraph of this covenant on the property so acquired;

(14) any encumbrances or restrictions of the type referred to in clauses (1), (2) and (3) of the first paragraph above imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1), (2) and (5) above, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Board of Directors, no more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing; or

(15) any encumbrance or restriction of a Securitization Subsidiary effected in connection with a Qualified Securitization Financing;provided,however, that such restrictions apply only to such Securitization Subsidiary.

Merger, Consolidation or Sale of Assets

Consolidation, Merger or Sale of Assets of the Issuer

The Issuer may not, directly or indirectly: (1) consolidate or merge with or into or wind up into another Person (whether or not the Issuer is the surviving Person); or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person; unless:

(1) either: (a) the Issuer is the surviving Person; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Issuer) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the jurisdiction of organization of the Issuer or the United States, any state of the United States, the District of Columbia or any territory thereof (the Issuer or such Person, as the case may be, hereinafter referred to as the Successor Company);

(2) the Successor Company (if other than the Issuer) expressly assumes all the obligations of the Issuer under the notes and the indenture pursuant to agreements reasonably satisfactory to the Trustee;

(3) immediately after such transaction no Default or Event of Default exists;

(4) after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, either (A) the Successor Company (if other than the Issuer), would have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of the covenant described above under “—Incurrence of Indebtedness and Issuance of Preferred Stock” determined on a pro forma basis (including pro forma application of the net proceeds therefrom), as if such transaction had occurred at

S-33

the beginning of such four-quarter period, or (B) the Fixed Charge Coverage Ratio for the Successor Company and its Restricted Subsidiaries would be greater than such ratio for the Issuer and its Restricted Subsidiaries immediately prior to such transaction;

(5) each Guarantor, unless it is the other party to the transactions described above, in which case clause (2) shall apply, shall have confirmed in writing that its Guarantee shall apply to such Person’s obligations under the notes and the indenture; and

(6) the Issuer shall have delivered to the Trustee a certificate from a Responsible Officer and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such amendment or supplement (if any) comply with the indenture.

The Successor Company will succeed to, and be substituted for, the Issuer under the indenture and the notes. Notwithstanding the foregoing clauses (3) and (4), (a) any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Issuer or to another Restricted Subsidiary and (b) the Issuer may merge with an Affiliate incorporated solely for the purpose of reincorporating the Issuer in a (or another) state of the United States, so long as the amount of Indebtedness of the Issuer and its Restricted Subsidiaries is not increased thereby.

Consolidation, Merger or Sale of Assets by a Guarantor

Subject to the provisions described under “—Guarantees—Release,” no Guarantor shall consolidate or merge with or into or wind up into (whether or not such Guarantor is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person, unless:

(1) such Guarantor is the surviving Person or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the United States, any state thereof, the District of Columbia or any territory thereof (such Guarantor or such Person, as the case may be, being herein called the Successor Guarantor);

(2) the Successor Guarantor (if other than such Guarantor) expressly assumes all the obligations of such Guarantor under the indenture pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee;

(3) immediately after such transaction no Default or Event of Default exists; and

(4) the Issuer shall have delivered to the Trustee a certificate from a Responsible Officer and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such amendment or supplement (if any) comply with the indenture.

The Successor Guarantor will succeed to, and be substituted for, such Guarantor under the indenture. Notwithstanding the foregoing, (1) a Guarantor may merge with an Affiliate incorporated solely for the purpose of reincorporating such Guarantor in another state of the United States, the District of Columbia or any territory thereof, so long as the amount of Indebtedness of the Guarantor is not increased thereby, (2) any Guarantor may merge into or transfer all or part of its properties and assets to the Issuer or another Guarantor and (3) a transfer of assets or Capital Stock of any Guarantor shall be permitted (including all or substantially all the assets of any Guarantor),provided such transfer complies with the covenant described under “—Limitation on Asset Sales.” Notwithstanding anything to the contrary herein, except as expressly permitted under the indenture no Guarantor shall be permitted to consolidate with, merge into or transfer all or part of its properties and assets to the Parent Guarantor.

S-34

Transactions with Affiliates

The Issuer will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an Affiliate Transaction) involving aggregate consideration in excess of $10.0 million, unless:

(1) the Affiliate Transaction is on terms that are not materially less favorable, taken as a whole, to the Issuer or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person on an arms-length basis; and

(2) the Issuer delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $40.0 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members, if any, of the Board of Directors.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph:

(1) transactions between or among the Issuer and/or any Restricted Subsidiary or any entity that becomes a Restricted Subsidiary as a result of such transaction or any entity that is an Affiliate solely as a result of the Issuer or any Restricted Subsidiary owning Capital Stock thereof;

(2) Restricted Payments and Permitted Investments (other than pursuant to clause (12) thereof) permitted by the indenture;

(3) the payment of reasonable and customary fees paid to, and indemnities provided on behalf of, officers, directors, employees or consultants of the Issuer, any Restricted Subsidiary or (to the extent such person renders services to the businesses of the Issuer and its Subsidiaries) any of the Issuer’s direct or indirect parent entities;

(4) transactions in which the Issuer or any Restricted Subsidiary delivers to the Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to the Issuer or such Restricted Subsidiary from a financial point of view;

(5) payments or loans (or cancellations of loans) to employees or consultants of the Issuer, any Restricted Subsidiary or (to the extent such person renders services to the businesses of the Issuer and its Subsidiaries) any of the Issuer’s direct or indirect parent entities, which are approved by a majority of the Board of Directors in good faith and which are otherwise permitted under the indenture;

(6) payments made or performance under any agreement as in effect on the Issue Date or any amendment thereto (so long as any such amendment is not less advantageous to the holders of the notes in any material respect than the original agreement as in effect on the Issue Date);

(7) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of the indenture that are fair to the Issuer or the Restricted Subsidiaries, in the reasonable determination of the members of the Board of Directors or the senior management of the Issuer, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

(8) if otherwise permitted hereunder, the issuance of Equity Interests (other than Disqualified Stock);

(9) any transaction effected as part of a Qualified Securitization Financing;

(10) any employment agreements entered into by the Issuer or any of the Restricted Subsidiaries in the ordinary course of business;

S-35

(11) transactions with joint ventures for the purchase or sale of chemicals, equipment and services entered into in the ordinary course of business; and

(12) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, pension plans, stock options and stock ownership plans approved by the Board of Directors.

Business Activities

The Issuer will not, and will not permit any Restricted Subsidiary (other than a Securitization Subsidiary) to, engage in any business other than Permitted Businesses, except to such extent as would not be material to the Issuer and its Subsidiaries taken as a whole.

Payments for Consent

The Issuer will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the indenture or the notes unless such consideration is offered to be paid and is paid to all holders of the notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Additional Guarantees

After the Issue Date, the Issuer will cause each Restricted Subsidiary that guarantees any Indebtedness of the Issuer or any of the Guarantors under the Credit Agreement, in each case, substantially at the same time, to execute and deliver to the Trustee a Guarantee pursuant to which such Restricted Subsidiary will unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any and interest on the notes and all other obligations under the indenture on the same terms and conditions as those set forth in the indenture.

Reports

Whether or not required by the Commission, so long as any notes are outstanding, the Issuer will electronically file with the Commission by the respective dates specified in the Commission’s rules and regulations (the Required Filing Date), unless, in any such case, such filings are not then permitted by the Commission:

(1) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Issuer were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Issuer’s certified independent accountants; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Issuer were required to file such reports;

If such filings with Commission are not then permitted by the Commission, or such filings are not generally available on the Internet free of charge, the Issuer will, within 15 days of each Required Filing Date, transmit by mail to holders of the notes, as their names and addresses appear in the note register, without cost to such holders of the notes, and file with the Trustee copies of the information or reports that the Issuer would be required to file with the Commission pursuant to the first paragraph if such filing were then permitted.

S-36

So long as the Parent Guarantor complies with the requirements of Rule 3-10 of Regulation S-X promulgated by the Commission (or any successor provision), the reports, information and other documents required to be filed and furnished to holders of the notes pursuant to this covenant may, at the option of the Issuer, be filed by and be those of the Parent Guarantor rather than the Issuer.

The availability of the foregoing reports on the Commission’s EDGAR service (or successor thereto) shall be deemed to satisfy the Issuer’s delivery obligations to the Trustee and holders.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

Events of Default and Remedies

Under the indenture, an Event of Default is defined as any of the following:

(1) the Issuer defaults in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any, on the notes;

(2) the Issuer defaults in the payment when due of interest on or with respect to the notes and such default continues for a period of 30 days;

(3) the Issuer defaults in the performance of, or breaches any covenant, warranty or other agreement contained in the indenture (other than a default in the performance or breach of a covenant, warranty or agreement which is specifically dealt with in clauses (1) or (2) above) and such default or breach continues for a period of 60 days after the notice specified below;

(4) a default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Issuer or any Restricted Subsidiary (other than Indebtedness under a Qualified Securitization Financing) or the payment of which is guaranteed by the Issuer or any Restricted Subsidiary (other than Indebtedness under a Qualified Securitization Financing) (other than Indebtedness owed to the Issuer or a Restricted Subsidiary), whether such Indebtedness or guarantee now exists or is created after the Issue Date, if (A) such default either (1) results from the failure to pay any such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or (2) relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity and (B) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $100.0 million or more at any one time outstanding;

(5) certain events of bankruptcy affecting the Issuer or any Significant Subsidiary;

(6) the Issuer or any Significant Subsidiary fails to pay final judgments (other than any judgments covered by insurance policies issued by reputable and creditworthy insurance companies) aggregating in excess of $100.0 million, which final judgments remain unpaid, undischarged and unstayed for a period of more than 60 days after such judgment becomes final, and an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed; or

(7) any Guarantee of a Significant Subsidiary fails to be in full force and effect (except as contemplated by the terms thereof) or any Guarantor (other than the Parent Guarantor) denies or disaffirms its obligations under its Guarantee and such Default continues for 10 days.

S-37

If an Event of Default (other than an Event of Default specified in clause (5) above with respect to the Issuer) shall occur and be continuing, the Trustee or the holders of at least 25% in principal amount of outstanding notes under the indenture may declare the principal of and accrued interest on such notes to be due and payable by notice in writing to the Issuer and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration” (the Acceleration Notice), and the same shall become immediately due and payable. Notwithstanding the foregoing, if an Event of Default specified in clause (5) above with respect to the Issuer occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holder of the notes.

The indenture will provide that, at any time after a declaration of acceleration with respect to the notes issued under the indenture as described in the preceding paragraph, the holders of a majority in principal amount of the outstanding notes issued under the indenture may rescind and cancel such declaration and its consequences:

(1) if the rescission would not conflict with any judgment or decree;

(2) if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

(4) if the Issuer has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

(5) in the event of the cure or waiver of an Event of Default of the type described in clause (5) of the description above of Events of Default, the Trustee shall have received an Officers’ Certificate and an opinion of counsel that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

The holders of a majority in principal amount of the notes issued under the indenture may waive any existing Default or Event of Default under the indenture, and its consequences, except a default in the payment of the principal of or interest on such notes.

In the event of any Event of Default specified in clause (4) of the first paragraph above, such Event of Default and all consequences thereof (excluding, however, any resulting payment default) will be annulled, waived and rescinded, automatically and without any action by the Trustee or the holders of the notes, if within 20 days after such Event of Default arose the Issuer delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the notes as described above be annulled, waived or rescinded upon the happening of any such events.

Holders of the notes may not enforce the indenture or the notes except as provided in the indenture and under the Trust Indenture Act of 1939, as amended. Subject to the provisions of the indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of any of the holders of the notes, unless such holders have offered to the Trustee reasonable indemnity. Subject to all provisions of the indenture and applicable law, the holders of a majority in aggregate principal amount of the then outstanding notes issued under such indenture have the right to 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.

S-38

The Issuer is required to deliver to the Trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default or Event of Default, the Issuer is required to deliver to the Trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor or any direct or indirect parent entity, as such, will have any liability for any obligations of the Issuer or any Guarantor under the notes, the indenture, any Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

The Issuer may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding notes issued under the indenture (“Legal Defeasance”) except for:

(1) the rights of holders of outstanding notes issued thereunder to receive payments in respect of the principal of, or interest or premium, if any, on such notes when such payments are due from the trust referred to below;

(2) the Issuer’s obligations with respect to the notes issued thereunder concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuer’s obligations in connection therewith; and

(4) the Legal Defeasance provisions of the indenture.

In addition, the Issuer may, at its option and at any time, elect to have the obligations of the Issuer released with respect to certain covenants that are described in the indenture (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the notes issued thereunder. In the event Covenant Defeasance occurs, certain events (not including nonpayment, bankruptcy, receivership, rehabilitation and insolvency events of the Issuer but not its Restricted Subsidiaries) described under “—Events of Default and Remedies” will no longer constitute an Event of Default with respect to the notes issued thereunder.

In order to exercise either Legal Defeasance or Covenant Defeasance under the indenture:

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the holders of the notes issued thereunder, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding notes issued thereunder on the stated maturity or on the applicable redemption date, as the case may be, and the Issuer must specify whether the notes are being defeased to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Issuer has delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee confirming that (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel will confirm that, the holders of the respective outstanding notes will not recognize

S-39

income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Issuer has delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee confirming that the holders of the respective outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting of Liens in connection therewith);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the indenture) to which the Issuer or any of its Restricted Subsidiaries is a party or by which the Issuer or any of its Restricted Subsidiaries is bound;

(6) the Issuer must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of preferring the holders of notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding creditors of the Issuer or others; and

(7) the Issuer must deliver to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Amendment, Supplement and Waiver

Except as provided in the next three succeeding paragraphs, the indenture or the notes issued thereunder may be amended or supplemented with the consent of the holders of at least a majority in principal amount of the notes then outstanding issued under the indenture (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes), and any existing default or compliance with any provision of the indenture or the notes issued thereunder may be waived with the consent of the holders of a majority in principal amount of the then outstanding notes issued under the indenture (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes).

Without the consent of each holder affected, an amendment or waiver of the indenture may not (with respect to any notes held by a non-consenting holder):

(1) reduce the principal amount of notes issued thereunder whose holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed maturity of any note or alter the provisions with respect to the redemption of the notes issued thereunder (other than provisions relating to the covenants described above under the caption “—Repurchase at the Option of Holders”);

(3) reduce the rate of or change the time for payment of interest on any note issued thereunder;

(4) waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the notes issued thereunder (except a rescission of acceleration of the notes issued thereunder by the holders of at least a majority in aggregate principal amount of the notes issued thereunder and a waiver of the payment default that resulted from such acceleration);

(5) make any note payable in money other than that stated in the notes;

S-40

(6) make any change in the provisions of the indenture relating to waivers of past Defaults or the rights of holders of notes to receive payments of principal of, or interest or premium, if any, on the notes issued thereunder;

(7) waive a redemption payment with respect to any note issued thereunder (other than a payment required by one of the covenants described above under the caption “—Repurchase at the Option of Holders”);

(8) modify the subsidiary Guarantees in any manner adverse to the holders of the notes; or

(9) make any change in the preceding amendment and waiver provisions.

Notwithstanding the preceding, without the consent of any holder of notes, the Issuer and the Trustee may amend or supplement the indenture or the notes issued thereunder:

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

(2) to provide for uncertificated notes in addition to or in place of certificated notes;

(3) to provide for the assumption of the Issuer’s obligations to holders of notes in the case of a merger or consolidation or sale of all or substantially all of the assets of the Issuer and its Subsidiaries;

(4) to make any change that would provide any additional rights or benefits to the holders of notes or that does not adversely affect the legal rights under the indenture of any such holder;

(5) to comply with requirements of the Commission in order to effect or maintain the qualification of the indenture under the Trust Indenture Act;

(6) to add a Guarantee of the notes;

(7) to release a Guarantor upon its sale or designation as an Unrestricted Subsidiary or other permitted release from its Guarantee;provided that such sale, designation or release is in accordance with the applicable provisions of the indenture; or

(8) to conform the text of any provision of the indenture, the notes or Guarantees to any provision of this description of the notes to the extent such provision was intended to be a verbatim recitation of such provision, which intent shall be conclusively evidenced by an officers’ certificate to that effect.

Satisfaction and Discharge

The indenture will be discharged and will cease to be of further effect as to all notes issued thereunder, when:

(1) either:

(a) all notes that have been authenticated, except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or

(b) all notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the sending of a notice of redemption or otherwise or will become due and payable by reason of the sending of a notice of redemption or otherwise within one year and the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the holders, cash in dollars, non-callable Government Securities, or a combination of cash in dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(2) the Issuer has paid or caused to be paid all sums payable by them under the indenture; and

S-41

(3) the Issuer has delivered irrevocable instructions to the Trustee under the indenture to apply the deposited money toward the payment of the notes issued thereunder at maturity or the redemption date, as the case may be.

In addition, the Issuer must deliver an Officers’ Certificate and an opinion of counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Concerning the Trustee

If the Trustee becomes a creditor of the Issuer, the indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign.

The holders of a majority in principal amount of the then outstanding notes issued under the indenture will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions. The indenture provides that in case an Event of Default occurs and is continuing, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of notes, unless such holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

S-50

of the Officers executing such Officers’ Certificate at the time of such execution and (iii) that any related incurrence of Indebtedness is permitted pursuant to the indenture. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness).

Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP.

S-64

BOOK-ENTRY, DELIVERY AND FORM

The notes will be issued in the form of one or more global securities that will be deposited with, or on behalf of, DTC. Global securities may be issued in either registered or bearer form and in either temporary or permanent form.

Beneficial interests in the global securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in DTC.

Investors may elect to hold their interests in the global securities through either (in the United States) DTC or (in Europe) through Clearstream or through Euroclear. Investors may hold their interests in the global securities directly if they are participants of such systems, or indirectly through organizations that are participants in these systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective US depositaries, which in turn will hold these interests in customers’ securities accounts in the depositaries’ names on the books of DTC. Except as set forth below, the global securities may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

Notes represented by a global security can be exchanged for definitive securities in registered form only if:

• DTC notifies us that it is unwilling or unable to continue as depositary for that global security and Celanese US does not appoint a successor depositary within 90 days after receiving that notice;

• at any time DTC ceases to be a clearing agency registered or in good standing under the Exchange Act, or other applicable statute or regulation and Celanese US does not appoint a successor depositary within 90 days after becoming aware that DTC has ceased to be registered as a clearing agency; or

• Celanese US determines that that global security will be exchangeable for definitive securities in registered form and notifies the trustee of its decision.

A global security that can be exchanged as described in the preceding sentence will be exchanged for definitive securities issued in authorized denominations in registered form for the same aggregate amount. The definitive securities will be registered in the names of the owners of the beneficial interests in the global security as directed by DTC.

We will make principal and interest payments on all notes represented by a global security to the paying agent which in turn will make payment to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the notes represented by a global security for all purposes under the indenture. Accordingly, we, the trustee and any paying agent will have no responsibility or liability for:

• any aspect of DTC’s records relating to, or payments made on account of, beneficial ownership interests in a note represented by a global security;

• any other aspect of the relationship between DTC and its participants or the relationship between those participants and the owners of beneficial interests in a global security held through those participants; or the maintenance, supervision or review of any of DTC’s records relating to those beneficial ownership interests.

DTC has advised us that its current practice is to credit participants’ accounts on each payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security as shown on DTC’s records, upon DTC’s receipt of funds and corresponding detail information. The underwriters or agents for the notes represented by a global security will initially designate the accounts to be credited. Payments by participants to owners of beneficial interests in a global security will be governed by

S-65

standing instructions and customary practices, as is the case with securities held for customer accounts registered in “street name,” and will be the sole responsibility of those participants. Book-entry notes may be more difficult to pledge because of the lack of a physical note.

DTC

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the notes represented by that global security for all purposes of the notes. Owners of beneficial interests in the notes will not be entitled to have notes registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered owners or holders of notes under the indenture. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if that person is not a DTC participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder of notes. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of the securities in certificated form. These laws may impair the ability to transfer beneficial interests in a global security. Beneficial owners may experience delays in receiving distributions on their notes since distributions will initially be made to DTC and must then be transferred through the chain of intermediaries to the beneficial owner’s account.

We understand that, under existing industry practices, if we request holders to take any action, or if an owner of a beneficial interest in a global security desires to take any action which a holder is entitled to take under the indenture, then DTC would authorize the participants holding the relevant beneficial interests to take that action and those participants would authorize the beneficial owners owning through such participants to take that action or would otherwise act upon the instructions of beneficial owners owning through them.

Beneficial interests in a global security will be shown on, and transfers of those ownership interests will be effected only through, records maintained by DTC and its participants for that global security. The conveyance of notices and other communications by DTC to its participants and by its participants to owners of beneficial interests in the notes will be governed by arrangements among them, subject to any statutory or regulatory requirements in effect.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Exchange Act.

DTC holds the securities of its participants and facilitates the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of its participants. The electronic book-entry system eliminates the need for physical certificates. DTC’s participants include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and certain other organizations, some of which, and/or their representatives, own DTC. Banks, brokers, dealers, trust companies and others that clear through or maintain a custodial relationship with a participant, either directly or indirectly, also have access to DTC’s book-entry system. The rules applicable to DTC and its participants are on file with the SEC.

DTC has advised us that the above information with respect to DTC has been provided to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

S-66

Clearstream

Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (Clearstream Participants) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. US Clearstream Participants are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures, to the extent received by the US depositary for Clearstream.

Euroclear

Euroclear has advised us that it was created in 1968 to hold securities for participants of Euroclear (Euroclear Participants) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear performs various other services, including securities lending and borrowing and interacts with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A/N.V. (the Euroclear Operator) under contract with Euroclear plc, a U.K. corporation. All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not Euroclear plc. Euroclear plc establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is a Belgian bank. As such it is regulated by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, herein the Terms and Conditions. The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants.

Distributions with respect to notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the US depositary for Euroclear.

S-67

Euroclear has further advised us that investors that acquire, hold and transfer interests in the notes by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global securities.

Global Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its US depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its US depositary to take action to effect final settlement on its behalf by delivering or receiving notes through DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to their respective US depositaries.

Because of time-zone differences, credits of notes received through Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such notes settled during such processing will be reported to the relevant Euroclear Participants or Clearstream Participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of notes by or through a Clearstream Participant or a Euroclear Participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

If the notes are cleared only through Euroclear and Clearstream (and not DTC), you will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices, and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers, and other institutions are open for business in the United States. In addition, because of time-zone differences, US investors who hold their interests in the securities through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, US investors who wish to exercise rights that expire on a particular day may need to act before the expiration date.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be modified or discontinued at any time. Neither we nor any paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

S-68

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain US federal income tax consequences of the acquisition, ownership and disposition of the notes. It is based on provisions of the Internal Revenue Code of 1986, as amended (the Code), existing and proposed Treasury regulations promulgated thereunder (the Treasury Regulations) and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis. No ruling from the Internal Revenue Service (the IRS) has been or is expected to be sought with respect to any aspect of the transactions described herein. Accordingly, no assurance can be given that the IRS will agree with the views expressed in this summary or that a court will not sustain any challenge by the IRS in the event of litigation.

This summary is limited to beneficial owners of notes that purchase the notes for cash upon their initial issuance at their initial offering price and that will hold the notes as capital assets within the meaning of Section 1221 of the Code. This summary does not address all of the US federal income tax consequences that may be relevant to particular holders in light of their personal circumstances, or to certain types of holders that may be subject to special tax treatment (such as banks and other financial institutions, real estate investment trusts and regulated investment companies, employee stock ownership plans, entities treated as partnerships for US federal income tax purposes or investors therein, former citizens or residents of the United States, controlled foreign corporations, corporations that accumulate earnings to avoid US federal income tax, insurance companies, tax-exempt organizations, dealers in securities, brokers, “US holders” (as defined below) whose functional currency is not the US dollar or who hold notes through a foreign entity or foreign account, persons subject to the alternative minimum tax or persons who hold the notes as a hedge or who hedge the interest rate on the notes). In addition, this summary does not include any discussion of the tax laws of any state, local or non-US government that may be applicable to a particular holder and does not consider any aspects of US federal tax law other than income taxation (such as estate and gift taxes).

For purposes of this discussion, a “US holder” is a beneficial owner of the notes that is, for US federal income tax purposes:

• an individual who is a citizen or resident of the United States;

• a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is subject to US federal income taxation regardless of its source; or

• a trust if (1) a court within the United States can exercise primary supervision over its administration, and one or more United States persons have the authority to control all of the substantial decisions of that trust or (2) the trust was in existence on August 20, 1996, and validly elected to continue to be treated as a US trust.

A “non-US holder” is a beneficial owner of the notes that is, for US federal income tax purposes, an individual, corporation, estate or trust that is not a US holder.

If an entity treated as a partnership for US federal income tax purposes holds the notes, the US federal income tax treatment of a partner in the partnership generally will depend on such partner’s particular circumstances and on the activities of the partnership. Partners in partnerships considering an investment in the notes should consult their own tax advisors.

If you are considering the purchase of the notes, you should consult your own tax advisor concerning the US federal income tax consequences to you in light of your own specific situation, and any consequences arising under other US federal tax laws or the laws of any other taxing jurisdiction.

S-69

Certain Contingent Payments

We may be obligated to pay an amount in excess of the stated interest and principal amount of the notes, as described under the heading “Description of the Notes—Repurchase at the Option of Holders—Change of Control Event.” Such a contingency could subject the notes to the provisions of the Treasury Regulations relating to “contingent payment debt instruments.” Under these regulations, however, one or more contingencies will not cause a debt instrument to be treated as a contingent payment debt instrument if, as of the issue date of the notes, such contingencies in the aggregate are “remote” or are considered to be “incidental.” We believe and intend to take the position that the possibility of our making such contingent payments should be treated as remote and/or incidental. Our position is binding on a holder, unless the holder discloses in the proper manner to the IRS that it is taking a different position. However, this determination is not binding on the IRS and is inherently factual, and we can give you no assurance that our position would be sustained if challenged by the IRS. A successful challenge of this position by the IRS could adversely affect the timing and amount of a holder’s income and would require a holder to treat any gain realized from a sale or other taxable disposition of a note as ordinary income rather than capital gain. The remainder of this disclosure assumes that the notes will not be considered contingent payment debt instruments. Holders are urged to consult their own tax advisors regarding the potential application to the notes of the contingent payment debt regulations and the consequences thereof.

Consequences to US Holders

Interest

Interest on the notes will be taxable to a US holder as ordinary interest income as the interest accrues or is paid in accordance with the holder’s regular method of tax accounting.

Sale or Other Disposition of the Notes

Upon a sale, exchange, redemption, retirement or other taxable disposition of a note, a US holder generally will recognize taxable gain or loss equal to the difference, if any, between (1) the amount of the cash and the fair market value of any property received on the sale or other taxable disposition (less an amount equal to any accrued and unpaid stated interest, which will be taxable as interest income as discussed above to the extent not previously included in income), and (2) the US holder’s adjusted tax basis in the note. A US holder’s adjusted tax basis in a note generally will be equal to the holder’s cost therefor. Any gain or loss realized on the sale or other taxable disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the disposition the US holder’s holding period in the note exceeds one year. Long-term capital gains of non-corporate US holders generally will be taxed at preferential rates. The deductibility of capital losses is subject to limitations.

Medicare Tax

For taxable years beginning after December 31, 2012, newly enacted legislation requires certain US holders who are individuals, estates or certain trusts to pay an additional 3.8% Medicare tax on the lesser of (1) the US person’s “net investment income” for the relevant taxable year and (2) the excess of the US person’s modified gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000 depending on the individual’s circumstances). Net investment income will generally include interest income and net gains from the disposition of the notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). A US holder that is an individual, estate or trust should consult its tax advisor regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the notes.

S-70

Backup Withholding and Information Reporting

In general, a US holder of the notes will be subject to backup withholding with respect to payments of stated interest on the notes, and the proceeds of a sale or other disposition (including a retirement or redemption) of the notes, at the applicable tax rate (currently at a rate of 28%, but scheduled to increase to 31% in 2013), unless such holder (a) is an entity that is exempt from backup withholding and, when required, demonstrates this fact, or (b) provides the applicable withholding agent with its taxpayer identification number (TIN), certifies that the TIN provided is correct and that the holder has not been notified by the IRS that such holder is subject to backup withholding due to prior underreporting of interest or dividends, and otherwise complies with applicable requirements of the backup withholding rules. In addition, such amounts will generally be subject to information reporting requirements. A US holder that does not provide the applicable withholding agent with its correct TIN may be subject to penalties imposed by the IRS.

Backup withholding is not an additional tax. Any amount withheld from a payment to a US holder may be allowed as a credit against such holder’s US federal income tax liability and may entitle such holder to a refund,providedthat the required information is timely furnished to the IRS.

Consequences to Non-US Holders

Payment of Interest

Subject to the discussion of backup withholding below, under the “portfolio interest exemption,” a non-US holder will generally not be subject to US federal income tax (or any withholding tax) on payments of interest on the notes that is not effectively connected with the non-US holder’s trade or business,providedthat:

• the non-US holder does not actually or constructively own 10% or more of the total combined voting power of all classes of stock of the Issuer entitled to vote;

• the non-US holder is not, and is not treated as, a bank receiving interest on an extension of credit pursuant to a loan agreement entered into in the ordinary course of its trade or business;

• the non-US holder is not a “controlled foreign corporation” that is related (actually or constructively) to the Issuer; and

• certain certification requirements are met.

Under current law, the certification requirement will be satisfied in any of the following circumstances:

• If a non-US holder provides to the applicable withholding agent a statement on an IRS Form W-8BEN (or suitable successor form), together with all appropriate attachments, signed under penalties of perjury, identifying the non-US holder by name and address and stating, among other things, that the non-US holder is not a United States person.

• If a note is held through a securities clearing organization, bank or another financial institution that holds customers’ securities in the ordinary course of its trade or business, (i) the non-US holder provides an IRS Form W-8BEN (or suitable successor form) to such organization or institution, and (ii) such organization or institution, under penalty of perjury, certifies to us that it has received such a form from the beneficial owner or another intermediary and furnishes the applicable withholding agent with a copy thereof.

• If a foreign financial institution or other foreign intermediary that holds the note on behalf of the non-US holder has entered into a withholding agreement with the IRS and submits an IRS Form W-8IMY (or suitable successor form) and certain other required documentation to the applicable withholding paying agent.

If the requirements of the portfolio interest exemption described above are not satisfied, a 30% withholding tax will apply to the gross amount of interest on the notes that is paid to a non-US holder, unless either: (a) an

S-71

applicable income tax treaty reduces or eliminates such tax, and the non-US holder claims the benefit of that treaty by providing a properly completed and duly executed IRS Form W-8BEN (or suitable successor or substitute form) establishing qualification for benefits under the treaty, or (b) the interest is effectively connected with the non-US holder’s conduct of a trade or business in the United States and the non-US holder provides an appropriate statement to that effect on a properly completed and duly executed IRS Form W-8ECI or W-8BEN, as applicable (or suitable successor form).

If a non-US holder is engaged in a trade or business in the United States and interest on a note is effectively connected with the conduct of that trade or business, the non-US holder will be required to pay US federal income tax on that interest on a net income basis in generally the same manner as a US holder, unless an applicable income tax treaty provides otherwise. If a non-US holder is eligible for the benefits of an income tax treaty between the United States and its country of residence, any interest income that is effectively connected with a US trade or business will be subject to US federal income tax in the manner specified by the treaty and generally will only be subject to such tax if such income is both effectively connected with the non-US holders’ trade or business in the United States and attributable to a permanent establishment (or a fixed base in the case of an individual) maintained by the non-US holder in the United States,providedthat the non-US holder claims the benefit of the treaty by properly submitting an IRS Form W-8BEN. In addition, a non-US holder that is treated as a foreign corporation for US federal income tax purposes may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of its earnings and profits for the taxable year, subject to adjustments, that are effectively connected with its conduct of a trade or business in the United States.

Sale or Other Disposition of the Notes

Subject to the discussion of backup withholding below, a non-US holder generally will not be subject to US federal income tax (or any withholding tax) on any gain realized by such holder upon a sale, exchange, redemption, retirement at maturity or other disposition of a note (other than any accrued and unpaid stated interest, which will be taxable as interest income as discussed above), unless:

• the non-US holder is an individual who is present in the US for 183 days or more during the taxable year of disposition and certain other conditions are met; or

• the gain is effectively connected with the conduct of a US trade or business of the non-US holder.

If the first exception applies, the non-US holder generally will be subject to US federal income tax at a rate of 30% on the amount by which its US-source capital gains exceed its US-source capital losses. If the second exception applies, the non-US holder will be subject to US federal income tax on the net gain derived from the sale or other disposition of the notes in generally the same manner as a US holder, unless an applicable income tax treaty provides otherwise. In addition, corporate non-US holders may be subject to a branch profits tax of 30% (or a lower applicable treaty rate) on any effectively connected earnings and profits, subject to adjustments. If a non-US holder is eligible for the benefits of an income tax treaty between the United States and its country of residence, the US federal income tax treatment of any such gain may be modified in the manner specified by the treaty.

Medicare Tax

As described in more detail above under “US holders – Medicare Tax,” newly enacted legislation imposes a 3.8% tax on certain investment income beginning in 2013. This tax does not apply to non-resident aliens. It is unclear at present whether this tax applies to non-US holders that are estates or trusts and that have one or more US beneficiaries. Such non-US holders should consult their own tax advisors regarding the potential consequences of the Medicare tax.

S-72

Information Reporting and Backup Withholding

When required, we or our paying agent will report to the IRS and to each non-US holder the amount of any interest paid on the notes in each calendar year, and the amount of US federal income tax withheld, if any, with respect to these payments. Copies of these information returns may also be made available to the tax authorities of the country in which you reside under the provisions of a specific treaty or agreement.

Payments of interest will be subject to backup withholding (currently at a rate of 28%, but scheduled to increase to 31% in 2013) unless the non-US holder certifies as to its non-US status or otherwise establishes an exemption from backup withholding, and will be subject to information reporting in any event.

Payments of the proceeds from a sale or other disposition (including a retirement or redemption) of a note to or through a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, information reporting, but not backup withholding, generally will apply to those payments (unless the non-US holder certifies its non-US status) if the broker is: (a) a United States person, (b) a controlled foreign corporation for US federal income tax purposes, (c) a foreign person 50% or more of whose gross income from all sources for the three-year period ending with the close of its taxable year preceding the payment was effectively connected with a US trade or business, or (d) a foreign partnership with specified connections to the United States.

Payment of the proceeds from a sale or other disposition (including a retirement or redemption) of a note to or through the United States office of a broker will be subject to information reporting and backup withholding unless the non-US holder certifies as to its non-US status or otherwise establishes an exemption from information reporting and backup withholding.

Backup withholding is not an additional tax. Any amount withheld from a payment to a non-US holder may be allowed as a credit against such holder’s US federal income tax liability and may entitle the holder to a refund,providedthe required information is timely furnished to the IRS.

UNDERWRITING

Deutsche Bank Securities Inc. is acting as representative of each of the underwriters named below. Subject to the terms and conditions set forth in a firm commitment underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of notes set forth opposite its name below.

Underwriter	Principal Amount of Notes
Deutsche Bank Securities Inc.	$	175,000,000
Merrill Lynch, Pierce, Fenner & Smith                       Incorporated		50,000,000
Citigroup Global Markets Inc.		50,000,000
HSBC Securities (USA) Inc.		50,000,000
J.P. Morgan Securities LLC		50,000,000
Barclays Capital Inc.		26,667,000
Commerz Markets LLC		15,000,000
Goldman, Sachs & Co.		15,000,000
Mitsubishi UFJ Securities (USA), Inc.		15,000,000
Morgan Stanley & Co. LLC		26,667,000
RBS Securities Inc.		26,666,000
Total	$	500,000,000

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The representative has advised us that the underwriters propose initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus supplement. After the initial offering, the public offering price or any other term of the offering may be changed. The underwriters may offer and sell notes through certain of their affiliates.

The expenses of the offering, not including the underwriting discount, are estimated at $1 million and are payable by us.

New Issue of Notes

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the

S-74

notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

Short Positions

In connection with the offering, the underwriters may purchase and sell the notes in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater principal amount of notes than they are required to purchase in the offering. The underwriters must close out any short position by purchasing notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. Deutsche Bank AG, New York Branch, an affiliate of Deutsche Bank Securities Inc., is the administrative agent and a lender under our senior credit facilities, and affiliates of certain of the other underwriters are agents or lenders under our senior credit facilities. As described under “Use of Proceeds,” we intend to use a portion of the net proceeds from this offering to repay a portion of certain outstanding term loans under our senior credit facilities, including debt that may be held by affiliates of certain of the underwriters.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Certain of the underwriters or their respective affiliates have a lending relationship with us, and as a result certain of these underwriters or their respective affiliates routinely hedge, and certain of those underwriters or their respective affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their respective affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our

S-75

securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

IMPORTANT INFORMATION ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission (SEC) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (Securities Act), using a “shelf “ registration process. Under this shelf process, we may sell any combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities offered by us. Each time we sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add to, update or change information contained in this prospectus; accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in the prospectus supplement. The prospectus supplement to be attached to the front of this prospectus may describe, as applicable: the terms of the securities offered, the initial public offering price, the price paid for the securities by any underwriters, net proceeds, the plan of distribution and the other specific terms related to the offering of the securities.

You should rely only on the information in this prospectus, and any supplement to this prospectus, including the information incorporated by reference. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not making an offer to sell the securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing or incorporated by reference in this prospectus and any prospectus supplement is accurate only as of the date indicated on the front cover of these documents or the date of the document incorporated by reference. Our business, financial condition, results of operations, and other information contained in the prospectus and any prospectus supplement may have changed since that date.

As used throughout this prospectus, unless the context otherwise requires or indicates:

• “Celanese” means Celanese Corporation, and not its subsidiaries;

• “Celanese US” means Celanese US Holdings LLC, a wholly-owned subsidiary of Celanese, and not its subsidiaries; and

• “Company,” “we,” “our” and “us” refer to Celanese and its subsidiaries, including Celanese US, on a consolidated basis.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain parts of this prospectus and any prospectus supplement, and the documents incorporated by reference contain forward-looking statements, as defined in Section 27A of the Securities Act, Section 21E of the Securities Exchange Act of 1934, as amended (Exchange Act), and the Private Securities Litigation Reform Act of 1995. You can identify these statements by the fact that they do not relate to matters of a strictly factual or historical nature and generally discuss or relate to forecasts, estimates or other expectations regarding future events. Generally, words such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “may,” “can,” “could,” “might,” “will” and similar expressions, as they relate to us, are intended to identify forward-looking statements. These statements reflect our current views and beliefs with respect to future events at the time that the statements are made, are not historical facts or guarantees of future performance and are subject to significant risks, uncertainties and other factors that are difficult to predict and many of which are outside of our control. Further, certain forward-looking statements are based upon assumptions as to future events that may not prove to be accurate and, accordingly, should not have undue reliance placed upon them.

The following factors could cause our actual results to differ materially from those results, performance or achievements that may be expressed or implied by such forward-looking statements. These factors include, among other things:

• changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate;

1

• the length and depth of product and industry business cycles particularly in the automotive, electrical, textiles, electronics and construction industries;

• changes in the price and availability of raw materials, particularly changes in the demand for, supply of, and market prices of ethylene, methanol, natural gas, wood pulp and fuel oil and the prices for electricity and other energy sources;

• the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases;

• the ability to maintain plant utilization rates and to implement planned capacity additions and expansions;

• the ability to reduce or maintain at their current levels production costs and improve productivity by implementing technological improvements to existing plants;

• increased price competition and the introduction of competing products by other companies;

• changes in the degree of intellectual property and other legal protection afforded to our products or technologies;

• costs and potential disruption or interruption of production due to accidents or other unforeseen events or delays in construction of facilities;

• potential liability for remedial actions and increased costs under existing or future environmental regulations, including those relating to climate change;

• potential liability resulting from pending or future litigation, or from changes in the laws, regulations or policies of governments or other governmental activities in the countries in which we operate;

• changes in currency exchange rates and interest rates;

• our level of indebtedness, which could diminish our ability to raise additional capital to fund operations or limit our ability to react to changes in the economy or the chemicals industry; and

• various other factors, both referenced and not referenced in this prospectus.

Additional information regarding these and other factors may be contained in our filings with the SEC incorporated herein by reference, especially on Forms 10-K, 10-Q and 8-K. Many of these factors are macroeconomic in nature and are, therefore, beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results, performance or achievements may vary materially from those described in this prospectus as anticipated, believed, estimated, expected, intended, planned or projected. Except as required by law, we neither intend nor undertake any obligation, and disclaim any duty to update these forward-looking statements, which speak only as of their respective dates.

DESCRIPTION OF CAPITAL STOCK

The following is a summary of select provisions of Celanese’s capital stock, as well as other certain provisions of Celanese’s Second Amended and Restated Certificate of Incorporation (Charter) and Third Amended and Restated By-laws (By-laws). The descriptions set forth below are qualified in their entirety by reference to the relevant provisions of the Charter and By-laws, copies of which have been filed as exhibits to the registration statement of which this prospectus forms a part.

Authorized Capitalization

As of March 31, 2011, Celanese’s authorized capital stock consisted of (i) 500,000,000 shares of common stock, par value $0.0001 per share, consisting of 400,000,000 shares of Series A common stock (Common Stock) of which 178,384,999 shares were issued and 156,046,321 shares were outstanding, and 100,000,000 shares of Series B common stock of which none were issued and outstanding, and (ii) 100,000,000 shares of preferred stock, par value $0.01 per share, of which none were issued and outstanding. Following the payment of a special dividend to holders of Celanese Series B common stock in April 2005, all of the then outstanding shares of Series B common stock automatically converted into shares of Celanese Series A common stock pursuant to our Charter.

Common Stock

Voting Rights.Holders of Common Stock are entitled to one vote per share on all matters with respect to which the holders of Common Stock are entitled to vote. The holders of Common Stock do not have cumulative voting rights in the election of directors.

Dividend Rights.Holders of Common Stock are entitled to receive dividends if, as and when dividends are declared from time to time by Celanese’s board of directors out of funds legally available for that purpose, after payment of dividends required to be paid on outstanding preferred stock, as described below, if any. The Company’s senior credit facilities and indentures impose restrictions on its ability to declare dividends with respect to Celanese’s Common Stock. Any decision to declare and pay dividends in the future will be made at the discretion of the board of directors and will depend on, among other things, results of operations, cash requirements, financial condition, contractual restrictions and factors that the board of directors may deem relevant.

Liquidation Rights.Upon liquidation, dissolution or winding up, the holders of Common Stock will be entitled to receive ratably the assets available for distribution to the stockholders after payment of liabilities and accrued but unpaid dividends and liquidation preferences on any outstanding preferred stock.

Other Matters.The Common Stock has no preemptive rights and, if fully paid, is not subject to further calls or assessment by Celanese. There are no redemption or sinking fund provisions applicable to the Common Stock. All shares of Celanese’s outstanding Common Stock are fully paid and non-assessable, and the shares of Celanese’s Common Stock offered under this registration statement, upon payment and delivery in accordance with the underwriting agreement, will be fully paid and non-assessable.

Preferred Stock

Celanese’s Charter authorizes the board of directors to establish one or more series of preferred stock and to determine, with respect to any series of preferred stock, the terms and rights of that series, including:

• the designation of the series;

• the number of shares of the series, which the board of directors may, except where otherwise provided in the preferred stock designation, increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares then outstanding);

• whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

• the dates at which dividends, if any, will be payable;

• the redemption rights and price or prices, if any, for shares of the series;

• the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

• the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of Celanese;

• whether the shares of the series will be convertible into shares of any other class or series, or any other security, of Celanese or any other corporation, and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

• restrictions on the issuance of shares of the same series or of any other class or series; and

• the voting rights, if any, of the holders of the series.

Anti-Takeover Effects of Certain Provisions of Our Charter and By-laws

Certain provisions of Celanese’s Charter and By-laws, which are summarized in the following paragraphs, may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by stockholders.

Classified Board of Directors

Celanese’s Charter provides that the board of directors will be divided into three classes of directors, with the classes to be as nearly equal in number as possible. The members of each class serve for a three-year term. As a result, approximately one-third of the board of directors will be elected each year. The classification of directors will have the effect of making it more difficult for stockholders to change the composition of the board of directors. Celanese’s Charter and the By-laws provide that the number of directors will be fixed from time to time pursuant to a resolution adopted by the board of directors, but must consist of not less than seven or more than fifteen directors.

Removal of Directors

Celanese’s Charter and By-laws provide that directors may be removed only for cause and only upon the affirmative vote of holders of at least 80% of the voting power of all the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. In addition, Celanese’s Charter also provides that any newly created directorships and any vacancies on the board of directors will be filled only by the affirmative vote of the majority of remaining directors.

No Cumulative Voting

The Delaware General Corporation Law (DGCL) provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless the charter provides otherwise. Celanese’s Charter does not expressly provide for cumulative voting.

Calling of Special Meetings of Stockholders; Stockholder Action by Written Consent

Celanese’s Charter provides that a special meeting of stockholders may be called at any time only by the chairman of the board of directors, the board or a committee of the board of directors which has been granted such authority by the board.

The DGCL permits stockholder action by written consent unless otherwise provided by a company’s charter. Celanese’s Charter precludes stockholder action by written consent.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Celanese’s By-laws provide that stockholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of stockholders must provide timely notice of their proposal in writing to the corporate secretary.

Generally, to be timely, a stockholder’s notice must be received at Celanese’s principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date on which the proxy materials for the previous year’s annual meeting were first mailed. Celanese’s By-laws also specify requirements as to the form and content of a stockholder’s notice. These provisions may impede stockholders’ ability to bring matters before an annual meeting of stockholders or make nominations for directors at an annual meeting of stockholders.

6

Supermajority Provisions

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote is required to amend a corporation’s certificate of incorporation or by-laws, unless the certificate of incorporation requires a greater percentage. Celanese’s Charter provides that the following provisions in the Charter and By-laws may be amended only by a vote of at least 80% of the voting power of all of the outstanding shares of our stock entitled to vote in the election of directors, voting together as a single class:

• classified board (the election and term of directors);

• the resignation and removal of directors;

• the provisions regarding stockholder action by written consent;

• the ability to call a special meeting of stockholders being vested solely in the chairman of the board of directors, the board of directors, or a committee of the board of directors (if duly authorized to call special meetings);

• filling of vacancies on the board of directors and newly created directorships;

• the advance notice requirements for stockholder proposals and director nominations; and

• the amendment provision requiring that the above provisions be amended only with an 80% supermajority vote.

In addition, Celanese’s Charter grants the board of directors the authority to amend and repeal the By-laws without a stockholder vote in any manner not inconsistent with the laws of the State of Delaware or Celanese’s Charter.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties. Celanese’s Charter includes a provision that eliminates the personal liability of directors for monetary damages for actions taken as a director, except for liability:

• for breach of duty of loyalty;

• for acts or omissions not in good faith or involving intentional misconduct or knowing violation of law;

• under Section 174 of the DGCL (unlawful dividends or stock repurchases and redemptions); or

• for transactions from which the director derived improper personal benefit.

Celanese’s Charter and By-laws provide that the company must indemnify its directors and officers to the fullest extent authorized by the DGCL. Celanese is also expressly authorized to advance certain expenses (including attorneys’ fees and disbursements and court costs) and carry directors’ and officers’ insurance providing indemnification for directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability and indemnification provisions in Celanese’s Charter and By-laws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit the company and its stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

7

There is currently no pending material litigation or proceeding involving any of Celanese’s directors, officers or employees for which indemnification is sought.

Delaware Anti-takeover Statute

Section 203 of the DGCL applies to Celanese. Under certain circumstances, Section 203 limits the ability of an interested stockholder to effect various business combinations with Celanese for a three-year period following the time that such stockholder becomes an interested stockholder. For purposes of Section 203, a “business combination” is broadly defined to include mergers, asset sales and other transactions resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or within the immediately preceding three years did own, 15% or more of Celanese’s voting stock.

An interested stockholder may not engage in a business combination transaction with Celanese within the three-year period unless:

• before the stockholder became an interested stockholder, the board approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

• upon consummation of the transaction in which the stockholder became an interested stockholder, the interested stockholder owned at least 85% of Celanese’s voting stock (excluding shares owned by officers, directors or certain employee stock purchase plans); or

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

Transfer Agent and Registrar

Computershare Trust Company, N.A. is the transfer agent and registrar for Celanese’s Common Stock.

Listing

Celanese’s Common Stock is listed on the NYSE under the symbol “CE.”

Authorized but Unissued Capital Stock

The DGCL does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the NYSE, which would apply so long as Celanese’s Common Stock is listed on the NYSE, require stockholder approval of certain issuances equal to or exceeding 20% of the then-outstanding voting power or then outstanding number of shares of Common Stock. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock may be to enable Celanese’s board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of the company by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of management and possibly deprive the stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

DESCRIPTION OF DEBT SECURITIES

AND GUARANTEES

The following is a general description of the debt securities that we may offer from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply to those securities will be described in the applicable prospectus supplement. As you read this section, please remember that the specific terms of a debt security as described in the applicable prospectus supplement will supplement and may modify or replace the general terms described in this section. If there are any differences between the applicable prospectus supplement and this prospectus, the applicable prospectus supplement will control. As a result, the statements we make in this section may not apply to the debt security you purchase.

The registered holder of any debt security will be treated as the owner of it for all purposes. Only registered holders will have rights under the applicable indenture.

General

The debt securities that we may offer will be either senior debt securities or subordinated debt securities. Any senior debt securities will be issued under an indenture, which we refer to as the senior indenture, to be entered into between us and the trustee named in the applicable prospectus supplement. Any subordinated debt securities will be issued under a different indenture, which we refer to as the subordinated indenture, to be entered into between us and the trustee named in the applicable prospectus supplement. We refer to both the senior indenture and the subordinated indenture as the indentures, and to each of the trustees under the indentures as a trustee. In addition, the indentures may be supplemented or amended as necessary to set forth the terms of the debt securities issued under the indentures. You should read the indentures, including any amendments or supplements, carefully to fully understand the terms of the debt securities. The terms of the debt securities will include those stated in the indentures and those made part of the indentures by reference to the Trust Indenture Act of 1939.

Any senior debt securities that Celanese US may issue will be our unsubordinated obligations. They will rank equally with each other and all of our other unsubordinated debt, unless otherwise indicated in the applicable prospectus supplement. Any subordinated debt securities that Celanese US may issue will be subordinated in right of payment to the prior payment in full of our senior debt. See “Ranking.” The subordinated debt securities will rank equally with each other, unless otherwise indicated in the applicable prospectus supplement. We will indicate in each applicable prospectus supplement, as of the most recent practicable date, the aggregate amount of our outstanding debt that would rank senior to the subordinated debt securities.

The indentures will not limit the amount of debt securities that can be issued thereunder and will provide that debt securities of any series may be issued thereunder up to the aggregate principal amount that we may authorize from time to time. Unless otherwise provided in the applicable prospectus supplement, the indentures will not limit the amount of other indebtedness or securities that Celanese US may issue. Celanese US may issue debt securities of the same series at more than one time and, unless prohibited by the terms of the series, we may reopen a series for issuances of additional debt securities without the consent of the holders of the outstanding debt securities of that series. All debt securities issued as a series, including those issued pursuant to any reopening of a series, will vote together as a single class.

Reference is made to the prospectus supplement for the following and other possible terms of each series of the debt securities with respect to which this prospectus is being delivered:

• the title of the debt securities;

9

• any limit upon the aggregate principal amount of the debt securities of that series that may be authenticated and delivered under the applicable indenture, except for debt securities authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, other debt securities of that series;

We will comply with Section 14(e) under the Exchange Act, to the extent applicable, and any other tender offer rules under the Exchange Act that may then be applicable, in connection with any obligation to purchase debt securities at the option of the holders thereof. Any such obligation applicable to a series of debt securities will be described in the prospectus supplement relating thereto.

11

Unless otherwise described in a prospectus supplement relating to any debt securities, there will be no covenants or provisions contained in the indentures that may afford the holders of debt securities protection in the event that we enter into a highly leveraged transaction.

The statements made hereunder relating to the indentures and any debt securities that Celanese US may issue are summaries of certain provisions thereof and are qualified in their entirety by reference to all provisions of the indentures and the debt securities and the descriptions thereof, if different, in the applicable prospectus supplement.

Payments on the Debt Securities

Principal of, premium, if any, and interest on the debt securities will be payable at the office or agency maintained by Celanese US for such purposes;providedthat all payments of principal, premium, if any, and interest with respect to the debt securities represented by one or more global securities registered in the name of or held by The Depository Trust Company (DTC) or its nominee will be made through the facilities of DTC. Until otherwise designated by Celanese US, Celanese US’s office or agency will be the office of the trustee maintained for such purpose.

Paying Agent and Registrar for the Debt Securities

The trustee will initially act as paying agent and registrar. Celanese US may change the paying agent or registrar without prior notice to the holders, and Celanese US, Celanese or any of their subsidiaries may act as paying agent or registrar.

Transfer and Exchange

A holder may transfer or exchange debt securities in accordance with the applicable indenture. Holders will be required to pay all taxes due on transfer. Celanese US will not be required to transfer or exchange any debt security selected for redemption or repurchase. Also, Celanese US will not be required to transfer or exchange any debt security for a period of 15 days before a selection of debt securities to be redeemed or repurchased.

Guarantees

The debt securities of any series will be guaranteed by Celanese and, to the extent specified in the applicable prospectus supplement, may be guaranteed by subsidiary guarantors. Each prospectus supplement will describe, as to the debt securities to which it relates, any guarantees by the subsidiary guarantors, including the terms of subordination, if any, of any such guarantee.

Ranking

Senior Debt Securities

Any series of senior debt securities will be general obligations of Celanese US that rank senior in right of payment to all existing and future indebtedness that is expressly subordinated in right of payment to the senior debt securities. Any series of senior debt securities will rank equally in right of payment with all existing and future liabilities of Celanese US that are not so subordinated. Any series of senior unsecured debt securities will be effectively subordinated to all of Celanese US’s secured indebtedness (to the extent of the value of the assets securing such indebtedness) and liabilities of our subsidiaries that do not guarantee the series of senior debt securities.

12

Subordinated Debt Securities

We will set forth in the applicable prospectus supplement the terms and conditions, if any, upon which any series of subordinated debt securities is subordinated to debt securities of another series or to our other indebtedness. The terms will include a description of:

• the indebtedness ranking senior to the debt securities being offered;

• the restrictions, if any, on payments to the holders of the debt securities being offered while a default with respect to the senior indebtedness is continuing; and

• the provisions requiring holders of the debt securities being offered to remit some payments to the holders of senior indebtedness.

Redemption

If specified in the applicable prospectus supplement, we may redeem the debt securities of any series, as a whole or in part, at our option on and after the dates and in accordance with the terms established for such series, if any, in the applicable prospectus supplement. If we redeem the debt securities of any series, we also must pay accrued and unpaid interest, if any, to the date of redemption on such debt securities.

Certain Covenants

Merger, Consolidation or Sale of Assets

Neither Celanese US nor Celanese may, directly or indirectly: (1) consolidate or merge with or into or wind up into another person (whether or not Celanese US is the surviving person); or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another person; unless:

(1) either: (a) Celanese US or Celanese, as the case may be, is the surviving person; or (b) the person formed by or surviving any such consolidation or merger (if other than Celanese US or Celanese, as the case may be) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the jurisdiction of organization of Celanese US or the United States, any state of the United States, the District of Columbia or any territory thereof (Celanese US or such person, as the case may be, hereinafter referred to as the Successor Company);

(2) the Successor Company (if other than Celanese US or Celanese, as the case may be) expressly assumes all the obligations of Celanese US or Celanese, as the case may be, under the debt securities and the applicable indenture;

(3) immediately after such transaction no default or Event of Default exists; and

(4) Celanese US or Celanese, as the case may be, shall have delivered to the trustee a certificate from a responsible officer and an opinion of counsel, each stating that such consolidation, merger or transfer and such amendment or supplement (if any) comply with the applicable indenture.

The Successor Company will succeed to, and be substituted for, Celanese US or Celanese, as the case may be, under the applicable indenture and the debt securities.

Reports

So long as any debt securities are outstanding, Celanese US shall file with the trustee, within 15 days after Celanese files with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the forgoing as the SEC may from time to time by rules and regulations

13

prescribe) that Celanese may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. Celanese US shall be deemed to have complied with the previous sentence to the extent that such information, documents and reports are filed with the SEC via EDGAR, or any successor electronic delivery procedure. Delivery of such reports, information and documents to the trustee is for informational purposes only and the trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including Celanese US’s compliance with any of its covenants under the applicable indenture (as to which the trustee is entitled to rely exclusively on officer’s certificates).

Events of Default and Remedies

The following will be “Events of Default” with respect to debt securities of a particular series, except to the extent provided in the supplemental indenture or resolution of our board of directors pursuant to which a series of debt securities is issued:

(1) Celanese US defaults in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any, on the debt securities;

(2) Celanese US defaults in the payment when due of interest on or with respect to the debt securities and such default continues for a period of 30 days;

(3) Celanese US defaults in the performance of, or breaches any covenant, warranty or other agreement contained in the applicable indenture (other than a default in the performance or breach of a covenant, warranty or agreement which is specifically dealt with in clauses (1) or (2) above) and such default or breach continues for a period of 90 days after the notice specified below;

(4) certain events of bankruptcy affecting Celanese US;

(5) Celanese’s guarantee with respect to such series of securities shall for any reason cease to be, or shall for any reason be asserted in writing by Celanese or Celanese US not to be, in full force and effect and enforceable in accordance with its terms except to the extent contemplated by the applicable indenture and such guarantee; or

(6) any other Event of Default provided in the applicable supplemental indenture or resolution of the board of directors under which such series of securities is issued or in the form of security for such series.

A default under one series of debt securities issued under the indenture will not necessarily be a default under another series of debt securities under the indenture. The trustee may withhold notice to the holders of a series of debt securities issued under such indenture of any default or event of default (except in any payment on the debt securities of such series) if the trustee considers it in the interest of the holders of the debt securities of that series to do so.

If an Event of Default (other than an Event of Default specified in clause (4) or (5) above) for a series of debt securities shall occur and be continuing, the trustee or the holders of at least 25% in principal amount of outstanding debt securities of that series may declare the principal of and accrued interest on such debt securities to be due and payable by notice in writing to Celanese US and the trustee specifying the respective Event of Default and that it is a “notice of acceleration” (Acceleration Notice), and the same shall become immediately due and payable. Notwithstanding the foregoing, if an Event of Default specified in clause (4) or (5) above occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding debt securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder of the debt securities.

The holders of a majority in principal amount of the debt securities of such series then outstanding may waive any existing default or Event of Default and its consequences, except a default in the payment of the principal of or interest on such debt securities.

14

Holders of debt securities of any series may not enforce the applicable indenture or the debt securities of that series except as provided in the applicable indenture and under the Trust Indenture Act of 1939, as amended. Subject to the provisions of the applicable indenture relating to the duties of the trustee, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of any of the holders of the debt securities of any series, unless such holders have offered to the trustee reasonable indemnity. Subject to all provisions of the applicable indenture and applicable law, the holders of a majority in aggregate principal amount of a series of the then outstanding debt securities of such series issued under such indenture will have the right to 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.

Celanese US and Celanese will be required to deliver to the trustee annually a statement regarding compliance with the indenture.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of Celanese, Celanese US or any guarantor subsidiary or any direct or indirect parent entity, as such, will have any liability for any obligations of Celanese, Celanese US or any guarantor subsidiary under the debt securities, the indenture, any guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of debt securities by accepting a debt security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the debt securities. The waiver may not be effective to waive liabilities under the federal securities laws.

Satisfaction and Discharge of Indenture

The indenture shall cease to be of further effect with respect to a series of debt securities when either:

(1) Celanese US has delivered to the trustee for cancellation all outstanding securities of such series, other than any securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in the indenture;

(2) all outstanding securities of such series have become due and payable or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice of redemption, and Celanese US or Celanese shall have irrevocably deposited with the trustee as trust funds the entire amount, in funds or governmental obligations, or a combination thereof, sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay at maturity or upon redemption all securities of such series; or

(3) Celanese US has properly fulfilled any other means of satisfaction and discharge that may be set forth in the terms of the securities of such series.

In each case, Celanese US will also pay all other sums payable by it under the indenture with respect to the securities of such series.

Defeasance

The term defeasance means the discharge of some or all of Celanese US’s obligations under the indenture. If Celanese US deposits with the trustee funds or government securities sufficient to make payments on any series of debt securities on the dates those payments are due and payable, then, at Celanese US’s option, either of the following will occur:

(1) Celanese US and Celanese will be discharged from obligations with respect to the debt securities of such series (legal defeasance); or

15

(2) Celanese US and Celanese will no longer have any obligation to comply with the restrictive covenants under the indenture, and the related events of default will no longer apply to us (covenant defeasance).

If Celanese US defeases any series of debt securities, the holders of the defeased debt securities of such series will not be entitled to the benefits of the indenture under which such series was issued, except for Celanese US’s obligation to register the transfer or exchange of the debt securities of such series, replace stolen, lost or mutilated debt securities or maintain paying agencies and hold moneys for payment in trust. In the case of covenant defeasance, Celanese US’s obligation to pay principal, premium and interest on the debt securities of such series will also survive. Celanese US 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 of such series to recognize income, gain or loss for federal income tax purposes. If Celanese US elects 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.

Amendment, Supplement and Waiver

Except as provided in the next two succeeding paragraphs, an indenture or the debt securities of any series issued thereunder may be amended or supplemented with the consent of the holders of at least a majority in principal amount of the debt securities of each series at the time outstanding that is affected voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, debt securities), and any existing default or compliance with any provision of the indenture or the debt securities of any series issued thereunder may be waived with the consent of the holders of a majority in principal amount of each series of debt securities at the time outstanding that is affected voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, debt securities).

Without the consent of each holder affected thereby, an amendment or waiver may not (with respect to any debt securities held by a non-consenting holder):

(1) reduce the amount of debt securities of any series whose holders must consent to an amendment, supplement or waiver;

(2) reduce the rate of or change the time for payment of interest on the debt securities of any series;

(3) reduce the principal or change the stated maturity of any debt securities of any series;

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

(5) make payments on any debt security payable in currency other than as originally stated in such debt security;

(6) impair the holder’s right to institute suit for the enforcement of any payment on any debt security;

(7) make any change in the percentage of principal amount of the debt securities of any series necessary to waive compliance with certain provisions of the indenture under which such debt securities were issued or to make any change in this provision for modification; or

(8) waive a continuing default or event of default regarding any payment on the debt securities of any series.

Notwithstanding the preceding, without the consent of any holder of debt securities, Celanese US, Celanese and the trustee may amend or supplement an indenture or the applicable debt securities issued thereunder:

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

16

(2) to provide for the assumption of the obligations of Celanese or Celanese US under the indenture by a successor upon any merger, consolidation or transfer of substantially all of the assets of Celanese US or Celanese, as applicable;

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

(4) to provide any security for or guarantees of the debt securities or for the addition of an additional obligor on the debt securities;

(5) to comply with any requirement to effect or maintain the qualification of the indenture under the Trust Indenture Act of 1939, as amended, if applicable;

(6) to add covenants that would benefit the holders of any outstanding series of debt securities or to surrender any rights of Celanese US or Celanese under the indenture;

(7) to add additional Events of Default with respect to any series of debt securities;

(8) to change or eliminate any of the provisions of the indenture, provided that any such change or elimination shall not become effective with respect to any outstanding debt security of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision;

(9) to provide for the issuance of and establish forms and terms and conditions of a new series of debt securities;

(10) to permit or facilitate the defeasance and discharge of the debt securities;

(11) to issue additional debt securities of any series; provided that such additional debt securities have the same terms as, and be deemed part of the same series as, the applicable series of debt securities to the extent required under the indenture;

(12) to make any change that does not adversely affect the rights of any holder of outstanding debt securities in any material respect; or

(13) to evidence and provide for the acceptance of appointment by a successor trustee with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the trust by more than one trustee.

Concerning the Trustee

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 man in the conduct of his own affairs. The trustee will become obligated to exercise any of its powers under the indenture at the request of any of the holders of any debt securities issued under the indenture only after those holders have furnished the trustee indemnity reasonably satisfactory to it.

If the trustee becomes a creditor of ours, it will be subject to limitations in the indenture on its rights to obtain payment of claims or to realize on certain property received for any such claim, as security or otherwise. The trustee is permitted to engage in other transactions with us. If, however, it acquires any conflicting interest, it must eliminate such conflict, resign or obtain an order from the SEC permitting it to remain as trustee.

Governing Law

The indentures, the debt securities and the guarantees will be governed by, and construed in accordance with, the laws of the State of New York.
