THE LOAN AGREEMENT

Exhibit 99.1

Please see “Certain Definitions” (beginning on page 27) for capitalized terms used in “The Loan Agreement” and “The Notes and The Senior Notes Indenture” but not defined in such sections.

THE LOAN AGREEMENT

The following summarizes certain provisions of the Amended and Restated Loan Agreement, dated as of July 2, 2010 (the “Agreement”), by and among the Louisiana Local Government Environmental Facilities and Community Development Authority (the “Authority”) and Westlake Chemical Corporation (the “Borrower”), to which reference is made for the detailed provisions thereof.

Payments by the Borrower under the Agreement

Pursuant to the Agreement, the Borrower will be required to make payments (“Payments”) to the Trustee (as defined below), under the Trust Indenture, dated as of July 2, 2010 (the “Indenture”), by and between the Authority and The Bank of New York Mellon Trust Company, N.A. (the “Trustee”), which will be sufficient to pay when due the principal of, premium, if any, and interest on the Authority’s $100 million aggregate principal amount of Revenue Bonds (Westlake Chemical Corporation Projects), Series 2009A due August 1, 2029 (the “Bonds”).

The Borrower will also pay as special Payments:

(i) “Change of Control Payment” being an amount sufficient for the payment in full in satisfaction of a Change of Control Offer. The Change of Control Payment with respect to the Bonds will be payable directly to the Trustee for the account of the Borrower Designee on the Change of Control Payment Date.

(ii) “Asset Sale Payment” being an amount sufficient for the payment in full in satisfaction of an Asset Sale Offer (as defined in the Senior Notes Indenture). The Asset Sale Payment with respect to the Bonds will be payable directly to the Trustee for the account of the Borrower on the completion of the Asset Sale Offer.

The Agreement also provides that the Borrower will pay the reasonable and necessary fees and expenses of the Trustee and any paying agents and any reasonable and necessary fees and expenses of the Authority caused by any default of the Borrower under the Agreement.

Obligations of the Borrower Unconditional

The obligation of the Borrower to make Payments pursuant to the Agreement, will be absolute and unconditional.

Prepayment and Redemption

The Borrower will have the option to prepay its obligations under the Agreement at the times and in the amounts as necessary to exercise its option to cause the Bonds to be redeemed as set forth in the Indenture and in the Bonds. The Borrower will agree that it will prepay its obligations under the Agreement at the times and in the amounts as necessary to accomplish the extraordinary mandatory redemption of the Bonds as set forth in the Indenture and in the Bonds. The Authority, at the request of the Borrower, will take all steps (other than the payment of the money required for such redemption) necessary under the applicable redemption provisions of the Indenture to effect redemption of all or part of the outstanding Bonds, as may be specified by the Borrower, on the date established for such redemption. Payments owed thereunder due to the early redemption of the Bonds will be paid to the Trustee on or prior to the date set for redemption thereof.

Issuance, Delivery and Surrender of Notes

In order to secure, on behalf of the Authority, the obligation of the Borrower to make the Payments, concurrently with the issuance and delivery by the Authority of the Bonds, the Borrower will issue and deliver to the Trustee the Borrower’s 6.50% Senior Notes due 2029 (the “Notes”) under the Senior Notes Indenture (i) maturing on the same date and in the same principal amount as the Bonds, (ii) bearing interest at an interest rate at all times equal to the interest rate borne by the Bonds, payable on the dates on which interest is payable on the Bonds, (iii) containing correlative redemption provisions to the Bonds, and (iv) subject to the provisions described in the following paragraph, requiring payments of the principal thereof and the premium, if any, and interest thereon to be made to the Trustee.

The obligation of the Borrower to make any payment of the principal of, premium, if any, or interest on the Notes, whether at maturity, upon redemption (including any redemption due to the occurrence of a Determination of Taxability with respect to the Bonds) or otherwise, will be fully or partially, as the case may be, deemed to have been paid or otherwise satisfied and discharged to the extent that at the time any such payment is due, the then due principal or purchase price of, premium, if any, or interest on the Bonds which corresponds to such amounts under the Notes has been fully or partially paid, deemed to have been paid or otherwise satisfied and discharged. In addition, such obligation to make any payment of the principal of, premium, if any, or interest on the Notes at any time will be deemed to have been satisfied and discharged to the extent that the amount of the Borrower’s obligation to make any payment of the principal of, premium, if any, or interest on the Notes exceeds the obligation of the Borrower at that time to make any Payment.

The Authority will not attempt to sell, assign or transfer the Notes, except to the extent of the assignment and pledge thereof to the Trustee under the Indenture. In view of such pledge and assignment, (i) the Notes will be issued and delivered to, registered in the name of and held by the Trustee for the benefit of the holders of the Bonds (the “Bondholders”) and in no respect will the Notes be deemed to be owned or held by or for the account, benefit or interest of the Borrower; (ii) the Senior Notes Indenture will provide that the Trustee will not sell, assign or transfer the Notes except to a successor trustee under the Indenture, and will surrender Notes to The Bank of New York Mellon Trust Company, N.A. (as successor to JPMorgan Chase Bank, National Association), as trustee under the Senior Notes Indenture (the “Notes Trustee”), in accordance with the provisions described in the following paragraph; and (iii) the Borrower may take such actions as it deems to be desirable to effect compliance with such restrictions on transfer, including the placing of an appropriate legend on the Notes and the issuance of stop-transfer instructions to the Notes Trustee or any other transfer agent under the Senior Notes Indenture.

At the time any Bonds cease to be outstanding (other than by reason of the payment or redemption of Notes), the Authority will cause the Trustee to surrender to the Notes Trustee a corresponding principal amount of the Notes, bearing interest at a rate equal to the interest rate borne by such Bonds, and maturing on the same date as such Bonds.

The Trustee, as a holder of the Notes, will have and exercise the remedies provided under the Senior Notes Indenture for holders of notes issued thereunder. To the extent that moneys recovered under the Senior Notes Indenture are insufficient to pay in full the Payments, the Borrower will remain liable for any such deficiency under the terms of the Agreement.

Covenants as to Arbitrage

The Borrower covenants that it will comply with the terms of its Tax Certificate dated the date of issuance of the Bonds and that it will make such use of the proceeds of the Bonds and all other funds held by the Trustee under the Indenture, regulate the investment of such proceeds and other funds and take such other and further action as may be required so that the Bonds will not constitute arbitrage bonds under Section 148 of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations promulgated thereunder. The Borrower agrees that it will comply with the terms of any letter of instructions provided to it by nationally recognized bond counsel relating to compliance with the provisions of Section 148 of the Code.

Assignment

The Borrower may assign its rights under the Agreement in whole or in part with the prior written approval of the Authority, but no such assignment will constitute a release of the Borrower from its obligations under the Agreement.

Amendment of the Agreement

Without the consent of Bondholders, but with the consent of the Trustee with respect to subparagraphs (d) and (e) below, the Authority and the Borrower may enter into supplements to the Agreement which are not inconsistent with the terms and provisions thereof for any of the purposes specifically authorized in the Agreement or the Indenture, and for the following purposes:

(a) to cure any ambiguity or formal defect, inconsistency or provide omitted language in the Agreement or to clarify matters or questions arising thereunder;

(b) to add covenants and agreements for the purpose of further securing the obligations of the Borrower thereunder;

(d) to conform the provisions of the Agreement in connection with the provisions of any supplements or amendments to the Indenture entered into pursuant to the Indenture without the consent of Bondholders;

(e) to provide any other modifications which, in the sole judgment of the Trustee, are not prejudicial to the interests of the Bondholders; or

(f) to conform the covenants and provisions of the Borrower contained in the Agreement to any different financial statement presentation required by the Financial Accounting Standard Board which is different than the presentation required as of the date of issuance of the Bonds, so long as the effect of such conformed covenants and provisions is substantially identical to the effect of the covenants and provisions as in effect on the date of issuance of the Bonds.

The Agreement may be amended in any particular manner with the written consent of the owners of not less than a majority in aggregate principal amount of the then Outstanding Bonds; provided, however, that no such amendment may be adopted which decreases the percentage of owners of Bonds required to approve any amendment, or which permits a change in the date of payment of the principal of or interest on any Bonds or of any redemption price thereof or the rate of interest thereon.

In connection with any amendment of the Agreement, there also must be delivered to the Authority and the Trustee a written opinion of bond counsel (which counsel and opinion, including without limitation, the scope, form, substance and other aspects thereof, are acceptable to the Trustee) to the effect that under existing laws the proposed supplement or amendment would not adversely affect the validity of the Bonds or the exclusion otherwise available from gross income of interest on the Bonds for federal or state income tax purposes.

Events of Default

The following events are events of default under the Agreement:

(a) An Event of Default exists under the Indenture, the Notes or the Senior Notes Indenture;

(b) The Borrower defaults in the timely payment of any Payment pursuant to the Agreement; provided that such default with respect to an Interest Payment will be deemed to occur upon the continuance of any such failure of payment for a period of 30 days after the applicable Interest Payment Date;

(c) The Borrower fails duly to perform, observe or comply with any other covenant, condition or agreement on its part under the Agreement (other than a failure to make any Payment required under the Agreement), and such failure continues for a period of 30 days after the date on which written notice of such failure, requiring the same to be remedied, has been given to the Borrower by the Trustee; provided, however, that if such performance, observation or compliance requires work to be done, action to be taken, or conditions to be remedied, which by their nature cannot reasonably be done, taken or remedied, as the case may be, within such 30 day period, no Event of Default will be deemed to have occurred or to exist if, and so long as the Borrower commences such performance, observation or compliance within such period and diligently and continuously prosecutes the same to completion;

(d) The entry of a decree or order by a court having jurisdiction in the premises adjudging the Borrower a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Borrower under the United States Bankruptcy Code or any other applicable federal or state law, or appointing a receiver, liquidator, custodian, assignee, or sequestrator (or other similar official) of the Borrower or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for it period of 90 consecutive days; and

(e) The institution by the Borrower of proceedings to be adjudicated a bankrupt or insolvent, or the consent by it to the institution of bankruptcy or insolvency against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under the United States Bankruptcy Code or any other similar applicable federal or state law, or the consent by it to the filing of any such petition or to the appointment of a receiver, liquidator, custodian, assignee, trustee or sequestrator (or other similar official) of the Borrower or of any substantial part of its property, or the making by it of all assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due.

Remedies

Whenever any Event of Default under the Agreement has happened and is continuing, any one or more of the following remedial steps may be taken:

(a) The Authority or the Trustee may declare all Payments to be immediately due and payable, whereupon the same will be immediately due and payable;

(b) The Authority or the Trustee may take whatever action at law or in equity may appear necessary or desirable to collect the Payments then due and thereafter to become due, or to enforce performance and observance of any obligation, agreement or covenant of the Borrower under the Agreement;

(c) The Authority or the Trustee may have access to and inspect, examine and make copies of any and all books, accounts and records of the Borrower; and

(d) The Authority or the Trustee (or the owners of the Bonds in the circumstances permitted by the Indenture) may exercise any option and pursue any remedy provided by the Indenture.

Payments under subparagraphs (a) and (b) above will be deemed to have been made to the extent of any corresponding payments by the Borrower upon an Event of Default (as defined in the Senior Notes Indenture) under the Notes.

THE NOTES AND THE SENIOR NOTES INDENTURE

The following summarizes certain provisions of the Notes and the Senior Notes Indenture, to which reference is made for the detailed provisions thereof.

The Notes

The Notes will be:

•

general unsecured obligations of the Borrower;

•

pari passu in right of payment with any senior Indebtedness of the Borrower and any senior Indebtedness of the Subsidiary Guarantors, including, in each case, the Public Notes and any Indebtedness and other Obligations outstanding under a Credit Facility;

•

senior in right of payment to any future subordinated Indebtedness of the Borrower;

•

unconditionally guaranteed by the Subsidiary Guarantors; and

•

non-transferable, except to a successor or assign of the Trustee under the Indenture.

The Guarantees

The Borrower’s payment obligations under the Notes will be unconditionally guaranteed by each of the Subsidiary Guarantors. Each of these Guarantees will be:

•

general unsecured obligations of the Subsidiary Guarantors;

•

pari passu in right of payment with any senior Indebtedness of the Borrower and any senior Indebtedness of such Subsidiary Guarantor, including the Public Notes and any Indebtedness and other Obligations outstanding under a Credit Facility; and

•

senior in right of payment to any future subordinated Indebtedness of such Subsidiary Guarantor.

Not all of the Borrower’s subsidiaries will guarantee the Notes. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor subsidiaries, that non-guarantor subsidiary will pay the holders of its debt and its trade creditors before it will be able to distribute any of its assets to the Borrower. The non-guarantor subsidiaries generated 1.68% of the Borrower’s consolidated net sales for the year ended December 31, 2009 and held 3.43% of the Borrower’s consolidated assets as of March 31, 2010.

As of the date of the Supplemental Indenture, all of the Borrower’s Subsidiaries will be “Restricted Subsidiaries,” other than Westlake Trinidad Unlimited, Westlake International Investments Corporation, Westlake International Services Corporation, Suzhou Huasu Plastics Co., Ltd., Westlake Profiles Limited, Westech Building Products Limited, Westlake International Holdings C.V., Westlake International LLC, Westlake International Holdings Coöperatief U.A., Westlake International I B.V. and Westlake International II B.V. However, under the circumstances described below under the caption “Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” the Borrower will be permitted to designate certain subsidiaries as “Unrestricted Subsidiaries.” The Borrower’s Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the Senior Notes Indenture. The Borrower’s Unrestricted Subsidiaries will not guarantee the Notes.

Certain Covenants

Certain covenants will apply under the Senior Notes Indenture for the benefit of the Holder of the Notes.

Covenant Suspension

During any period of time that (i) the Bonds are rated Investment Grade and (ii) no Default or Event of Default under the Senior Notes Indenture has occurred and is continuing, the Borrower and its Restricted Subsidiaries will no longer be subject to the following provisions of the Senior Notes Indenture (described below):

•

“Restricted Payments”

•

“Dividend and Other Payment Restrictions Affecting Subsidiaries”

•

“Incurrence of Indebtedness and Issuance of Preferred Stock”

•

“Asset Sales”

•

“Liens” and

•

Clause (4) under “Limitations on Mergers, Consolidations and Sales of Assets” (collectively, the “Affected Covenants”).

In the event that the Borrower and its Restricted Subsidiaries are not subject to the Affected Covenants for any period of time as a result of the preceding sentence and, subsequently, the Bonds are not rated Investment Grade, then the Borrower and its Restricted Subsidiaries will thereafter be subject to the Affected Covenants and compliance with respect to Restricted Payments made after the time of a rating withdrawal or downgrade will be calculated in accordance with the provisions described below under “Restricted Payments” as if such covenant had been in effect since the date of execution of the Supplemental Indenture.

Restricted Payments

(a) The Borrower will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other distribution on account of the Borrower’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Borrower or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Borrower’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Borrower or to the Borrower or a Restricted Subsidiary of the Borrower);

(2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Borrower) any Equity Interests of the Borrower or any direct or indirect parent of the Borrower;

(3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value, any Indebtedness of the Borrower or any Subsidiary Guarantor that is contractually subordinated to the Notes any Guarantee (excluding any interBorrower Indebtedness between or among the Borrower and any of its Restricted Subsidiaries), except a payment of interest or principal at or after the Stated Maturity of such interest or principal; or

(4) make any Restricted Investment in an Unrestricted Subsidiary

(all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment:

(i) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; and

(ii) the Borrower would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth below in the first paragraph under “Incurrence of Indebtedness and Issuance of Preferred Stock”; and

(iii) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Borrower and its Restricted Subsidiaries since the date of the Supplemental Indenture (excluding Restricted Payments permitted by clauses (2), (3), (4), (6), (7), (8), (9), (10), (11), (12) and (13) of the next full paragraph (b) below), is less than the sum, without duplication, of:

(a) 50% of the Consolidated Net Income of the Borrower for the period (taken as one accounting period) from October 1, 2003 to the end of the Borrower’s most recently ended fiscal quarter for which financial statements are available in accordance with “Other Reports” below at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus

(b) 100% of the aggregate proceeds (including the Fair Market Value of any non-cash consideration) received by the Borrower since October 1, 2003 as a contribution to its common equity capital or by the Borrower or any of its Restricted Subsidiaries from the issue or sale of Equity Interests of the Borrower (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Borrower or any of its Restricted Subsidiaries that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Borrower), plus

(c) to the extent that any Restricted Investment that was made after October 1, 2003 is sold for cash or otherwise liquidated, repaid for cash or otherwise reduced, including by way of dividend, on or before January 13, 2006 (or in the case of any Restricted Investment in any Unrestricted Subsidiary so designated after January 13, 2006, so sold, liquidated, repaid or otherwise reduced on or after January 13, 2006), the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment, plus

(d) to the extent that any Unrestricted Subsidiary of the Borrower designated as such after January 13, 2006 is redesignated as a Restricted Subsidiary, the Fair Market Value of the Borrower’s Investment in such Subsidiary as of the date of such redesignation, plus

(e) 50% of the net reduction in Investments in Unrestricted Subsidiaries designated as such January 13, 2006 or Joint Ventures resulting from any dividends, repayment of loans or other transfer of assets received by the Borrower or a Restricted Subsidiary of the Borrower after October 1, 2003 from any such Unrestricted Subsidiary or a Joint Venture, to the extent that such dividends, repayments or transfers were not otherwise included in Consolidated Net Income of the Borrower for such period.

(b) So long as no Default has occurred and is continuing or would be caused thereby, the preceding provisions will not prohibit:

(1) the payment of any dividend within 60 days after the date of declaration of the dividend, if at the date of declaration the dividend payment would have complied with the provisions of the Senior Notes Indenture;

(2) the making of any Restricted Payment in exchange for, or out of the net cash proceeds of the substantially concurrent issuance or sale (other than to a Subsidiary of the Borrower) of, Equity Interests of the Borrower (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to the Borrower; provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition will be excluded from clause (iii)(b) of the preceding paragraph;

(3) the defeasance, redemption, repurchase or other acquisition of Indebtedness of the Borrower or any Subsidiary Guarantor that is contractually subordinated to the Notes or to any Guarantee with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness;

(4) the payment of any dividend (or, in the case of any partnership or limited liability Borrower, any similar distribution) by a Restricted Subsidiary of the Borrower to the Borrower or another Restricted Subsidiary, or the purchase, redemption, or other acquisition or retirement of any Equity Interests in a Restricted Subsidiary held by the Borrower or another Restricted Subsidiary;

(5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Borrower or any Restricted Subsidiary of the Borrower held by any current or former officer, director or employee of the Borrower or any of its Restricted Subsidiaries pursuant to any equity subscription agreement, stock option agreement, shareholders’ agreement or similar plan or agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed the greater of (i) 0.2% of Consolidated Net Tangible Assets and (ii) $5.0 million in any twelve-month period;

(6) the repurchase of Equity Interests deemed to occur upon the exercise of stock options to the extent such Equity Interests represent a portion of the exercise price of those stock options;

(8) distributions or payments of Receivables Fees;

(9) the repurchase of any Indebtedness of the Borrower or any Subsidiary Guarantor that is contractually subordinated to the Notes or to any Guarantee at a purchase price not greater than 101% of the principal amount thereof in the event of (x) a Change of Control (pursuant to a provision no more favorable to the holders thereof than the provision described under “Change of Control” below) or (y) an Asset Sale (pursuant to a provision no more favorable to the holders thereof than the provision described under “Asset Sales” below); provided that in each case, prior to such repurchase the Borrower has made a Change of Control Offer or Asset Sale Offer, as applicable, and repurchased all Notes that were validly tendered for payment in connection with such Change of Control Offer or Asset Sale Offer;

(10) the payment of dividends on common stock of the Borrower at a rate not to exceed $0.20 per share per quarter (such amount to be appropriately adjusted to reflect any stock split, reverse split, stock dividend or similar transaction made after the date of execution of the Supplemental Indenture so that the aggregate amount of dividends payable after such transaction is the same as the amount payable prior to such transaction);

(13) other Restricted Payments in an aggregate amount not to exceed the greater of (i) 5.0% of Consolidated Net Tangible Assets and (ii) $100.0 million outstanding at any time.

(c) 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 Borrower or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities of $50.0 million or greater that are required to be valued by this covenant will be determined by the Board of Directors whose resolution with respect thereto will be delivered to the Trustee.

(d) For purposes of this section, “substantially concurrent” will be deemed to mean within at least 45 days.

Dividend and Other Payment Restrictions Affecting Subsidiaries

The Borrower 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 Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock to the Borrower or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Borrower or any of its Restricted Subsidiaries;

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

(3) transfer any of its properties or assets to the Borrower or any of its Restricted Subsidiaries.

The preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements governing Existing Indebtedness and Credit Facilities as in effect on the date of the Supplemental Indenture and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of the Supplemental Indenture;

(2) the Senior Notes Indenture, the Notes and the related Guarantees;

(3) applicable law, rule, regulation or order;

(4) any agreement or instrument governing Indebtedness or Capital Stock of a Person as in effect at the time of the acquisition by the Borrower or any of its Restricted Subsidiaries of such Person or the properties or assets of such Person (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Senior Notes Indenture to be incurred;

(5) customary non-assignment provisions in contracts and leases entered into in the ordinary course of business;

(6) construction loans and purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that impose restrictions on the property constructed, purchased or leased of the nature described in clause (4) in the second paragraph under “Incurrence of Indebtedness and Issuance of Preferred Stock” below, relating to Permitted Debt;

(7) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by that Restricted Subsidiary pending the sale or other disposition;

(8) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(9) Liens securing Indebtedness otherwise permitted to be incurred under the provisions described under “Liens” below that limit the right of the debtor to dispose of the assets subject to such Liens;

(10) any restriction under an agreement governing Indebtedness of a Foreign Subsidiary permitted under “Incurrence of Indebtedness and Issuance of Preferred Stock” below;

(11) provisions limiting or prohibiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into with the approval of the Borrower’s Board of Directors, which limitation or prohibition is applicable only to the assets that are the subject of such agreements;

(12) any agreement or instrument governing Indebtedness permitted to be incurred under the Senior Notes Indenture, provided that the terms and conditions of any such restrictions and encumbrances, taken as a whole, are not materially more restrictive than those contained in the Senior Notes Indenture, taken as a whole; and

(13) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

For purposes of determining compliance with the provisions described above under this heading, in the event that a restriction meets the criteria of more than one of the categories of permitted restrictions described in clauses (1) through (13) above, the Borrower will be permitted to classify such restriction on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant.

Incurrence of Indebtedness and Issuance of Preferred Stock

The Borrower 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 Borrower will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Borrower may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock and the Restricted Subsidiaries may incur Indebtedness or issue preferred stock, if the Fixed Charge Coverage Ratio for the Borrower’s most recently ended four full fiscal quarters for which financial statements are available in accordance with “Other Reports” below would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom and, in the case of Acquired Debt, giving pro forma effect to the applicable transaction related thereto), as if the additional Indebtedness had been incurred (and such transaction had occurred) or the preferred stock or Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period.

The provisions described in the preceding paragraph will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by the Borrower or any Restricted Subsidiary of Indebtedness and letters of credit under one or more Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Borrower and its Subsidiaries thereunder) not to exceed the greater of (i) 30.0% of Consolidated Net Tangible Assets or (ii) $600.0 million;

(2) the incurrence by the Borrower and its Restricted Subsidiaries of the Existing Indebtedness;

(3) the incurrence by the Borrower and the Subsidiary Guarantors of Indebtedness represented by the notes and the related guarantees to be issued pursuant to the Senior Notes Indenture;

(4) the incurrence by the Borrower or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used or usable in a Permitted Business, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of (i) 1.0% of Consolidated Net Tangible Assets and (ii) $20.0 million at any time outstanding;

(5) the incurrence by the Borrower or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refund, refinance, renew, defease or replace Indebtedness (other than intercompany Indebtedness) that was permitted by the Senior Notes Indenture to be incurred under the first paragraph above under this heading or clause (2), (3), (4), (5), (16) or (17) of this paragraph;

(6) the incurrence by the Borrower or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Borrower and any of its Restricted Subsidiaries; provided, however, that:

(A) if the Borrower or any Subsidiary Guarantor is the obligor on such Indebtedness and the payee is not the Borrower or a Subsidiary Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in the case of the Borrower, or the Guarantee, in the case of a Subsidiary Guarantor; and

(B)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Borrower or a Restricted Subsidiary of the Borrower and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either the Borrower or a Restricted Subsidiary of the Borrower will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Borrower or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the issuance by any of the Borrower’s Restricted Subsidiaries to the Borrower or to any of its Restricted Subsidiaries of shares of preferred stock; provided, however, that:

(A) any subsequent issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Borrower or a Restricted Subsidiary of the Borrower; and

(B) any sale or other transfer of any such preferred stock to a Person that is not either the Borrower or a Restricted Subsidiary of the Borrower;

will be deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (7);

(8) the incurrence by the Borrower or any of its Restricted Subsidiaries of Hedging Obligations in the ordinary course of business and not for speculative purposes;

(9) the guarantee by the Borrower or any of its Restricted Subsidiaries of Indebtedness of the Borrower or a Restricted Subsidiary of the Borrower that was permitted to be incurred by another provision described under this heading; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the guarantee will be subordinated to the same extent as the Indebtedness guaranteed;

(10) the incurrence by the Borrower or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims; self-insurance or similar obligations; the financing of insurance premiums; bankers’ acceptances; performance, appeal, bid completion, guarantee and surety bonds; or similar requirements (and, in all cases, letters of credit in respect thereof) in the ordinary course of business;

(12) the incurrence by Foreign Subsidiaries of Indebtedness in an aggregate principal amount at any time outstanding pursuant to this clause (12), including all Permitted Refinancing Indebtedness incurred to refund, refinance, defease, renew, extend or replace Indebtedness incurred pursuant to this clause (12), not to exceed the greater of (i) 5.0% of Consolidated Net Tangible Assets and (ii) $100.0 million;

(14) the incurrence by the Borrower or a Restricted Subsidiary of Indebtedness consisting of take-or-pay obligations contained in supply agreements entered into in the ordinary course of business;

(15) the incurrence by the Borrower of Indebtedness to any of its Subsidiaries incurred in connection with the purchase of accounts receivable and related assets by the Borrower from any such Subsidiary which assets are subsequently conveyed by the Borrower in connection with a Receivable Facility; and

(16) the incurrence by the Borrower or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to extend, refund, refinance, renew, defease or replace any Indebtedness incurred pursuant to this clause (16), and the issuance by the Borrower of any Disqualified Stock and by any Restricted Subsidiary of any additional preferred stock, not to exceed the greater of (i) 5.0% of Consolidated Net Tangible Assets and (ii) $100.0 million; and

(17) the incurrence or issuance, as the case may be, by the Borrower or any Restricted Subsidiary of Acquired Debt, Acquired Preferred Stock or Acquired Disqualified Stock; provided that immediately after giving effect to such incurrence or issuance, as the case may be, (i) the Fixed Charge Coverage Ratio for the Borrower’s most recently ended four full fiscal quarters for which financial statements are available preceding the date of such incurrence or issuance, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom) as if such Acquired Debt, Acquired Preferred Stock or Acquired Disqualified Stock had been incurred or issued at the beginning of such four-quarter period, would be (x) at least 2.0 to 1 or (y) equal to or greater than it would have been immediately preceding such incurrence or (ii) the Consolidated Net Worth of the Borrower would be greater than the Consolidated Net Worth of the Borrower immediately prior to such transaction.

The Borrower will not incur, and will not permit any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Pari Passu Indebtedness of the Borrower or such Subsidiary Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Borrower solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis.

For purposes of determining compliance with the covenant described under this heading, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (17) above, or is entitled to be incurred pursuant to the first paragraph above under this heading, the Borrower will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant. Indebtedness under Credit Facilities outstanding on the date on which Notes are first issued and authenticated under the Senior Notes Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount thereof is included in Fixed Charges of the Borrower as accrued. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Borrower or any Restricted Subsidiary may incur pursuant to this covenant will not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

Asset Sales

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

(1) the Borrower or the Restricted Subsidiary, as the case may be, receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (as determined by the Borrower’s Board of Directors and evidenced by a resolution of the Board of Directors set forth in an Officers’ Certificate delivered to the Trustee as to Asset Sales having a Fair Market Value of $50.0 million or greater) 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 Borrower or such Restricted Subsidiary is in the form of cash or Cash Equivalents, publicly traded equity securities of a Person with a market capitalization (not held by Affiliates of such Person) of at least $500 million or a controlling interest in, or long-term assets used or useful in, a business engaged in a Permitted Business. For purposes of this provision, each of the following will also be deemed to be cash:

(A) any liabilities, as shown on its most recent balance sheet, of the Borrower or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Borrower or such Restricted Subsidiary from further liability;

(B) any securities, notes or other obligations received by the Borrower or any such Restricted Subsidiary from such transferee that are promptly, subject to ordinary settlement periods, converted or monetized by the Borrower or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion or monetization; and

Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Borrower or the applicable Restricted Subsidiary, as the case may be, may apply those Net Proceeds, at its option, to any one or more of the following:

(1) to repay Indebtedness and other Obligations of the Borrower and its Restricted Subsidiaries;

(2) to acquire all or substantially all of the assets of, or any Capital Stock of, any Person or division conducting a Permitted Business, if, in the case of any such acquisition of Capital Stock and after giving effect thereto, such Person will be a Restricted Subsidiary of the Borrower (or enter into a binding commitment for any such acquisition); provided that such binding commitment will be treated as a permitted application of Net Proceeds from the date of such commitment until and only until the earlier of (x) the date on which such acquisition is consummated and (y) the 180th day following the expiration of the aforementioned 360-day period. If the acquisition or expenditure contemplated by such binding commitment is not consummated on or before such 180th day and the Borrower or such Restricted Subsidiary has not applied such Net Proceeds pursuant to clause (1), (3) or (4) of this paragraph on or before such 180th day, such commitment will be deemed not to have been a permitted application of Net Proceeds;

(3) to make a capital expenditure; or

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business;

provided, however, that to the extent that the Asset Sale consists, directly or indirectly, of Domestic Assets, in order to qualify under any of the foregoing clauses (1) through (4) of this paragraph, the Borrower must apply such proceeds to acquire additional Domestic Assets, acquire assets located in the United States or a Person described in clause (2) above which will become a Domestic Subsidiary at the time it becomes a Restricted Subsidiary pursuant thereto, make domestic capital expenditures or repay Indebtedness that is an obligation of the Borrower or a Subsidiary Guarantor.

Pending the final application of any Net Proceeds, the Borrower may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by the Senior Notes Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.” On the 361st day after the Asset Sale (or, at the Borrower’s option, any earlier date), if the aggregate amount of Excess Proceeds exceeds $25.0 million, the Borrower will make an Asset Sale Offer to all holders of the Bonds and to all holders of other Pari Passu Indebtedness, including the Public Notes (collectively, an “Asset Sale Offer”), in respect of which an offer to purchase is also required to purchase the maximum principal amount of Bonds 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. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Borrower may use those Excess Proceeds for any purpose not otherwise prohibited by the Senior Notes Indenture. If the aggregate principal amount of Bonds and other Pari Passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Notes Trustee will select the Bonds and such other Pari Passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

To the extent that the provisions of any securities laws or regulations conflict with the Change of Control or Asset Sale provisions of the Senior Notes Indenture, the Borrower will comply with the applicable securities laws and regulations and the Borrower will not be deemed to have breached its obligations under the Change of Control or Asset Sale provisions of the Senior Notes Indenture by virtue of such conflict.

Notwithstanding the provisions described in the preceding paragraphs (other than the proviso in the second full paragraph under this heading), the Borrower and its Restricted Subsidiaries may consummate an Asset Sale without complying with such provisions if (i) at least 80% of the consideration for such Asset Sale is in the form of assets used or useful in a Permitted Business and (ii) such Asset Sale is for at least Fair Market Value.

Transactions with Affiliates

The Borrower 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 of the Borrower (each, an “Affiliate Transaction”), unless:

(1) the Affiliate Transaction is on terms that are no less favorable to the Borrower or the relevant Restricted Subsidiary than those that might reasonably have been obtained in a comparable transaction by the Borrower or such Restricted Subsidiary with an unrelated Person; and

(2) the Borrower delivers to the Trustee:

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this covenant and such Affiliate Transaction been approved by a majority of the members of the Board of Directors; and

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $50.0 million, (i) a Board Resolution certifying that such Affiliate Transaction complies with clause (1) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors, if any, or if there are no such disinterested members, then (ii)(x) an opinion as to the fairness to the Borrower or such Restricted Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing or (y) with respect to assets classified, in accordance with GAAP, as property, plant or equipment, a written appraisal from a nationally recognized appraiser showing the assets have a Fair Market Value of not less than the consideration paid (provided that if the Fair Market Value determined by such appraiser is a range of values or otherwise inexact, the Board of Directors will determine the exact Fair Market Value within such range).

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

(1) any fees, compensation and other payments paid to any officer or employee pursuant to any employment agreement, employee or director benefit plan, officer and director indemnification agreement or any similar arrangement entered into by the Borrower or any of its Restricted Subsidiaries in the ordinary course of business;

(2) transactions between or among the Borrower and/or its Restricted Subsidiaries;

(3) transactions with a Person (other than an Unrestricted Subsidiary of the Borrower) that is an Affiliate of the Borrower solely because the Borrower owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) payment of reasonable directors’ fees to Persons who are not otherwise Affiliates of the Borrower;

(5) any issuance of Equity Interests (other than Disqualified Stock) of the Borrower to Affiliates of the Borrower;

(6) Restricted Payments that do not violate the provisions described under “Restricted Payments” above;

(7) loans or advances to employees in the ordinary course of business not to exceed $10.0 million in the aggregate at any one time outstanding;

(8) sales (including a sale in exchange for a promissory note of or Equity Interest in such Accounts Receivable Subsidiary) of accounts receivable, related assets and the provision of billing, collection and other services in connection therewith, in each case, to an Accounts Receivable Subsidiary in connection with any Receivables Facility;

(9) transactions pursuant to any contract or agreement in effect on the Issue Date, as the same may be amended, modified, extended or replaced from time to time, so long as any such contract or agreement as so amended, modified, extended or replaced is, taken as a whole, not materially less favorable to the Borrower and its Restricted Subsidiaries than under those agreements in effect on the Issue Date;

(10) any transaction or series of transactions between the Borrower or any Restricted Subsidiary and any of their Joint Ventures or any Unrestricted Subsidiary, provided that (a) such Affiliate Transaction complies with clause (1) of the initial paragraph above, and (b) with respect to any such Affiliate Transaction involving aggregate consideration in excess of the greater of (i) 0.5% of Consolidated Net Tangible Assets and (ii) $10.0 million, such Affiliate Transaction has been approved by the Board of Directors;

(11) transactions between the Borrower or its Restricted Subsidiaries and any Person who becomes an Unrestricted Subsidiary or Joint Venture pursuant to agreements entered into before, and not in contemplation of, the consummation of any such transaction;

(12) Permitted Investments;

(13) transactions entered into by a Person prior to the time such Person becomes a Subsidiary or is merged or consolidated into the Borrower or a Subsidiary (provided such transaction is not entered into in contemplation of such event); and

(14) transactions with any customer, client, supplier, distributor or any other purchaser or seller of goods or services (including, without limitation, with any Unrestricted Subsidiary), in each case in the ordinary course of business and otherwise in compliance with the terms of the Senior Notes Indenture, which when taken together with other transactions with the same Person are, in the reasonable determination of the Board of Directors or senior management of the Borrower, fair to the Borrower and its Restricted Subsidiaries or on terms not less favorable than might have been obtained in a comparable transaction at such time on an arm’s length basis from a person who is not an Affiliate.

Liens

The Borrower will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien, except Permitted Liens, to secure Indebtedness of any kind on any asset now owned or hereafter acquired, unless all payments due under the Senior Notes Indenture and the Notes are secured on an equal and ratable basis with the obligations so secured (or, if such obligations are subordinated by their terms to the Notes or the related Guarantees, prior to the obligations so secured) until such time as such obligations are no longer secured by a Lien.

Additional Guarantees

If, after the date of the Supplemental Indenture, any Domestic Subsidiary of the Borrower that is not already a Subsidiary Guarantor (including, without limitation, any Domestic Subsidiary acquired or created after the date of the Supplemental Indenture) guarantees any other Indebtedness in excess of $5 million of either of the Borrower or a Subsidiary Guarantor, then in either case that Subsidiary will become a Subsidiary Guarantor by executing a supplemental indenture and delivering it to the Notes Trustee within 15 Business Days of the date on which it guaranteed or incurred such Indebtedness, as the case may be. Notwithstanding the preceding, any guarantee of a Domestic Subsidiary that was incurred pursuant to this paragraph as a result of a guarantee of any other Indebtedness in excess of $5 million will provide by its terms that it will be automatically and unconditionally released upon the release or discharge of the guarantee that resulted in the creation of such Domestic Subsidiary’s Guarantee, except a discharge or release by, or as a result of payment under, such Guarantee.

Designation of Restricted and Unrestricted Subsidiaries

The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Borrower and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and, to the extent not otherwise permitted by the second paragraph under “Restricted Payments” above or under one or more clauses of the definition of Permitted Investments, as determined by the Borrower, will reduce the amount available for Restricted Payments as described under “Restricted Payments” above. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. If a Restricted Subsidiary that is a Subsidiary Guarantor is designated an Unrestricted Subsidiary in accordance with the terms of this covenant, such Guarantee will be released.

Sale and Leaseback Transactions

The Borrower will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Borrower or any Restricted Subsidiary may enter into a sale and leaseback transaction if:

(1) the Borrower or that Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the Fixed Charge Coverage Ratio test in the first paragraph of the covenant described under “Incurrence of Indebtedness and Issuance of Preferred Stock” above and (b) incurred a Lien to secure such Indebtedness pursuant to the covenant described under “Liens” above.

(2) the gross cash proceeds of that sale and leaseback transaction are at least equal to the Fair Market Value, as determined in good faith by the Board of Directors and set forth in an Officers’ Certificate delivered to the Notes Trustee, of the property that is the subject of that sale and leaseback transaction; and

(3) the transfer of assets in that sale and leaseback transaction is permitted by, and the Borrower applies the proceeds of such transaction in compliance with, the covenant described under “Asset Sales” above.

Accounts Receivable Facilities

Notwithstanding any other provisions of the Senior Notes Indenture, the Borrower or any of its Restricted Subsidiaries may sell (including a sale in exchange for a promissory note of or Equity Interest in such Accounts Receivable Subsidiary) at any time and from time to time, accounts receivable and related assets to any Accounts Receivable Subsidiary; provided that the aggregate consideration received in each such sale is at least equal to the aggregate Fair Market Value of the receivables sold.

Payments for Consent

The Borrower will not, and will not permit any of its Restricted 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 Senior Notes Indenture or the Notes unless such consideration is offered to be paid or agreed to be 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.

Other Reports

The Borrower will file with the SEC (unless the SEC will not accept such a filing)

(1) all quarterly and annual reports required to be filed with the SEC on Forms 10-Q and 10-K; and

(2) all current reports required to be filed with the SEC on Form 8-K,

for public availability within the time periods specified in the rules and regulations applicable to such reports.

If, at any time the Borrower is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Borrower will nevertheless continue filing the reports specified in the preceding paragraph with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Borrower agrees that it will not take any action for the purpose of causing the SEC not to accept any such filings. If the SEC will not accept the Borrower’s filings for any reason, the Borrower will post the reports referred to in the preceding paragraph on its website within the time periods that would apply if the Borrower were required to file those reports with the SEC.

Limitations on Mergers, Consolidations and Sales of Assets

The Borrower will not, directly or indirectly: (x) consolidate or merge with or into another Person (whether or not the Borrower is the surviving corporation); or (y) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of the Borrower and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

(1) either: (x) the Borrower is the surviving or continuing Person; or (y) the Person formed by or surviving any such consolidation or merger (if other than the Borrower) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a Person organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

(2) the Person formed by or surviving any such consolidation or merger (if other than the Borrower) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Borrower under the Notes and Senior Notes Indenture pursuant to agreements reasonably satisfactory to the Notes Trustee;

(3) immediately after giving effect to such transaction, no Default or Event of Default exists; and

(4) the Borrower or the Person formed by or surviving any such consolidation or merger (if other than Borrower), or to which such sale, assignment, transfer, conveyance or other disposition has been made will, on the date of such transaction 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, (i) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the test set forth in the first paragraph of the covenant described under “Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock” above, (ii) have a Fixed Charge Coverage Ratio that is not less than the Fixed Charge Coverage Ratio of the Borrower immediately prior to such transaction or (iii) have Consolidated Net Worth immediately after the transaction equal to or greater than the Consolidated Net Worth of the Borrower immediately preceding the transaction.

In addition, Borrower may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person.

The covenant described above will not apply to:

(A) a merger or consolidation of the Borrower with an Affiliate for the purpose of reincorporating or reorganizing Borrower in another jurisdiction;

(B) a merger or consolidation of the Borrower with a Wholly-Owned Restricted Subsidiary; provided that, in connection with any such merger or consolidation, no consideration, other than Equity Interests (other than Disqualified Stock) in the surviving or continuing Person or Borrower, will be issued or distributed to the holders of Equity Interests of the Borrower; and

(C) any sale, transfer, assignment, conveyance or other disposition of assets between or among the Borrower and its Restricted Subsidiaries.

Defaults and Remedies

Events of Default

Each of the following is an Event of Default under the Senior Notes Indenture with respect to the Notes:

(1) the failure by the Borrower to pay interest on any Note when the same becomes due and payable and the continuance of any such failure for a period of 30 days;

(2) the failure by the Borrower to pay the principal or premium of any Note when the same becomes due and payable at maturity, upon acceleration or otherwise;

(3) the failure by the Borrower or any Restricted Subsidiary to comply with the provisions described above under “Certain Covenants—Change of Control,” “—Asset Sales” or “Limitations on Mergers, Consolidations and Sales of Assets”;

(4) the Borrower or any Subsidiary Guarantor fails to comply with any of its other covenants or agreements in, or provisions of, the Notes or the Senior Notes Indenture (other than an agreement, covenant or provision that has expressly been included in the Senior Notes Indenture solely for the benefit of one or more series of Securities other than the Notes) which has not been remedied after written notice within the specified period under the Senior Notes Indenture;

(5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Borrower or any of its Significant Subsidiaries (or the payment of which is guaranteed by the Borrower or any of its Significant Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the date of the Supplemental Indenture, if that default:

(A) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

(B) results in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $40.0 million or more and has not been discharged in full or such acceleration has not been rescinded or annulled within 30 days of such maturity or acceleration;

(6) failure by the Borrower or any of its Significant Subsidiaries to pay or otherwise discharge or stay final judgments aggregating in excess of $40.0 million, which are not covered by indemnities or third party insurance as to which the Person giving such indemnity or such insurer has not disclaimed coverage, for a period of 60 days after such judgments become final and non-appealable;

(7) the occurrence of certain events of bankruptcy or insolvency with respect to the Borrower or any Restricted Subsidiary that is a Significant Subsidiary; or

(8) except as permitted by the Senior Notes Indenture, any Guarantee of the Notes pursuant to the Senior Notes Indenture ceases to be in full force and effect (other than in accordance with the terms of such Guarantee and the Senior Notes Indenture) or is declared null and void in a judicial proceeding or any Subsidiary Guarantor denies or disaffirms its obligations under the Senior Notes Indenture or its Guarantee (other than by reason of release of a Subsidiary Guarantor from its Guarantee in accordance with the terms of the Senior Notes Indenture and the Guarantee).

Acceleration

If an Event of Default with respect to the Notes (other than an Event of Default specified in clause (7) under “Events of Default” above) occurs and is continuing, the Trustee by notice to the Borrower and the Subsidiary Guarantors, or the Holders of at least 25% in principal amount of the then outstanding Notes (or, in the case of an Event of Default described in clause (4) under “Events of Default” above, if outstanding Securities of other series are affected by such Event of Default, then at least 25% in principal amount of the then outstanding Securities so affected) by notice to the Borrower, the Subsidiary Guarantors and the Notes Trustee, may declare the principal of and all accrued and unpaid interest on all then outstanding Notes or all series of Securities, as the case may be, to be due and payable. Upon any such declaration, the amounts due and payable on the Notes will be due and payable immediately. If an Event of Default specified in clause (7) under “Events and Default” above occurs, such amounts will ipso facto become and be immediately due and payable without any declaration, notice or other act on the part of the Notes Trustee or any Holder. The holders of a majority in principal amount of the then outstanding Securities of the series affected by such Event of Default or all series so affected, as the case may be, by written notice to the Notes Trustee may rescind an acceleration and its consequences (other than nonpayment of principal of or premium or interest on or any Additional Amounts with respect to the Securities) if (i) the rescission would not conflict with any judgment or decree, (ii) all existing Events of Default with respect to the Securities of that series (or of all series, as the case may be) have been cured or waived, except nonpayment of principal, premium, interest or any Additional Amounts that have become due solely because of the acceleration and (iii) the Notes Trustee has been paid any amounts due to it for the reasonable compensation, expenses, disbursements and advances of the Notes Trustee, its agents and counsel, and any other amounts due the Notes Trustee under the Senior Notes Indenture.

Amendments

Without the consent of the Holders

The Borrower, the Subsidiary Guarantors and the Notes Trustee may enter into supplements to the Senior Notes Indenture or the Notes without the consent of the Holders of the Notes for the following purposes:
