The Securities

SECTION 2.01. Form and Dating. Provisions relating to the Initial Securities and the Exchange Securities are set forth in the Rule 144A/Regulation S Appendix attached hereto (the “Appendix”) which is hereby incorporated in, and expressly made part of, this Indenture. The Initial Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in, and expressly made a part of, this Indenture. The Exchange Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture.

33

SECTION 2.02. Execution and Authentication. Two Officers shall sign the Securities for the Company by manual or facsimile signature.

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

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

On the Issue Date, the Trustee shall authenticate and deliver $425,000,000 of 7.75% Senior Secured Notes Due 2019 and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Company. Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with Section 4.03.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any Wholly Owned Subsidiary incorporated or organized within the United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

34

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Securities.

SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five business days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders.

SECTION 2.06. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(1) of the Uniform Commercial Code are met. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met.

SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

Every replacement Security is an additional Obligation of the Company.

35

SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

SECTION 2.10. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancellation and deliver a certificate of such destruction to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancellation.

SECTION 2.11. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the persons who are Securityholders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Securityholder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

36

SECTION 2.12. CUSIP Numbers, ISINs, etc. The Company in issuing the Securities may use “CUSIP” numbers, ISINs and “Common Code” numbers (in each case if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided , however , that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

SECTION 2.13. Issuance of Additional Securities. After the Issue Date, the Company shall be entitled, subject to its compliance with Section 4.03, to issue Additional Securities under this Indenture, which Securities shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. The Securities and the Additional Securities, if any, shall be treated as a single class for all purposes of this Indenture, including waivers, amendments, redemptions and offers to purchase; provided , however , that in the event that any Additional Securities are not fungible with the Securities for U.S. Federal income tax purposes, such nonfungible Additional Securities shall be issued with a separate CUSIP or ISIN number so that they are distinguishable from the Securities.

With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture and the provision of Section 4.03 that the Company is relying on to issue such Additional Securities;

(2) the issue price, the issue date and the CUSIP number of such Additional Securities; and

(3) whether such Additional Securities shall be Initial Securities or shall be issued in the form of Exchange Securities as set forth in Exhibit A.

Article 3

Redemption

SECTION 3.01. Notices to Trustee. If the Company elects to redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the Trustee in writing of the redemption date, the principal amount of Securities to be redeemed and the paragraph of the Securities pursuant to which the redemption will occur.

The Company shall give each notice to the Trustee provided for in this Section at least 60 days before the redemption date unless the Trustee consents to a shorter period. Such notice shall be accompanied by an Officers’ Certificate and an Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein.

37

SECTION 3.02. Selection of Securities to Be Redeemed. In the event that the Company chooses to redeem less than all of the Securities at any time, selection of the Securities for redemption shall be made by the Trustee either: (1) in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed, or (2) on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate. If a partial redemption is made with the proceeds of a Public Equity Offering, the Trustee shall select the Securities only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depository). The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Trustee selects shall be in principal amounts of $2,000 or any greater integral multiple of $1,000 thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

SECTION 3.03. Notice of Redemption. At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address, except that redemption notices may be mailed more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Securities or a satisfaction and discharge of this Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Security redeemed in accordance with provisions of this Indenture.

The notice shall identify the Securities to be redeemed and shall state:

(1) the redemption date;

(2) the redemption price;

(3) the name and address of the Paying Agent;

(4) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(5) if fewer than all the outstanding Securities are to be redeemed, the identification and principal amounts of the particular Securities to be redeemed;

(6) that, unless the Company defaults in making such redemption payment, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

(7) the “CUSIP” number, ISIN or “Common Code” number, if any, printed on the Securities being redeemed; and

38

(8) that no representation is made as to the correctness or accuracy of the “CUSIP” number, ISIN, or “Common Code” number, if any, listed in such notice or printed on the Securities.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section.

SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date), and such Securities shall be canceled by the Trustee. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 3.05. Deposit of Redemption Price. Prior to the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which have been delivered by the Company to the Trustee for cancellation.

SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate for the Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

Article 4

Covenants

SECTION 4.01. Payment of Securities. The Company shall promptly pay the principal of and interest on the Securities on the dates and in the manner provided in the Securities and in this Indenture. Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

39

SECTION 4.02. Reports to Holders. Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall file with the Commission, subject to the next sentence, and provide the Trustee and Holders with such annual and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections, such reports to be so filed and provided at the times specified for the filings of such reports. If, at any time, the Company is not subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue filing the reports specified in the preceding sentence with the Commission within the time periods required unless the Commission will not accept such a filing. The Company agrees that it shall not take any action for the purpose of causing the Commission not to accept such filings. If, notwithstanding the foregoing, the Commission will not accept such filings for any reason, the Company shall post the reports specified in the preceding sentence on its website within the time periods that would apply if the Company were required to file those reports with the Commission. To the extent any such report or information is not so filed or provided, as applicable, within the time periods specified and such information is subsequently filed or provided, as applicable, the Company will be deemed to have satisfied its obligations with respect thereto at such time and any Default with respect thereto shall be deemed to have been cured; provided that such cure shall not otherwise affect the rights of the Holders under Article 6 if Holders of at least 25% in principal amount of the then total outstanding Securities have declared the principal, premium, if any, and interest on the Securities to be due and payable and such declaration shall not have been rescinded or canceled prior to such cure.

At any time that any of the Company’s Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph shall include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

In addition, for so long as any Securities remain outstanding, the Company shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. The Company also shall comply with the other provisions of TIA § 314(a).

SECTION 4.03. Limitation on Incurrence of Additional Indebtedness. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, “incur”) any Indebtedness; provided , however , that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Company or any of its Restricted Subsidiaries that is or, upon such incurrence, becomes a Guarantor shall be entitled to incur Indebtedness (including, without limitation, Acquired Indebtedness) if on the date of the incurrence of such Indebtedness, after giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of the Company is greater than 2.0 to 1.0.

(5) Indebtedness represented by Capitalized Lease Obligations and Purchase Money Indebtedness of the Company and its Restricted Subsidiaries incurred in the ordinary course of business not to exceed, at any one time outstanding, the greater of (i) $35,000,000 and (ii) 5.0% of Total Assets of the Company and its Restricted Subsidiaries;

41

(7) Indebtedness owed to the Company or to a Restricted Subsidiary of the Company for so long as such Indebtedness is held by the Company or a Restricted Subsidiary of the Company; provided that (A) if as of any date any Person other than the Company or a Restricted Subsidiary of the Company holds any such Indebtedness, such date shall be deemed the incurrence of Indebtedness not constituting permitted Indebtedness under this clause (7) by the issuer of such Indebtedness; (B) any subsequent issuance or transfer of any Capital Stock which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary shall be deemed to constitute the incurrence of such Indebtedness by the obligor thereon; (C) if the Company is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Securities; and (D) if a Guarantor is the obligor on such Indebtedness, such Indebtedness is expressly subordinated to the prior payment in full in cash of all Obligations of such Guarantor with respect to its Guarantee;

(8) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided , however , that such Indebtedness is extinguished within five business days of the Company’s or any Restricted Subsidiary’s knowledge of its incurrence;

(9) Indebtedness of the Company or any of its Restricted Subsidiaries in respect of performance bonds, bankers’ acceptances, workers’ compensation claims, surety or appeal bonds, payment obligations in connection with self-insurance or similar obligations, and bank overdrafts (and letters of credit in respect thereof) in the ordinary course of business;

(14) additional Indebtedness of the Company and its Restricted Subsidiaries in an aggregate principal amount not to exceed $50,000,000 at any one time outstanding (which amount may, but need not, be incurred in whole or in part under the Credit Agreement).

42

(c) For purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness meets the criteria of more than one of clauses (1) through (14) of paragraph (b) above or is entitled to be incurred pursuant to the Consolidated Fixed Charge Coverage Ratio provisions of paragraph (a) above, the Company shall, in its sole discretion, be entitled to divide and classify (or later reclassify) an item of Indebtedness in more than one of the types of Indebtedness described above; provided that all Indebtedness outstanding under the Credit Agreement up to the maximum amount permitted under clause (2) of paragraph (b) above shall be deemed to have been incurred pursuant to such clause (2). Accrual of interest, 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 Capital Stock in the form of additional shares of the same class of Disqualified Capital Stock shall not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Capital Stock for purposes of this Section 4.03.

(d) The Company shall not, and shall not permit any Restricted Subsidiary that is a Guarantor to, directly or indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is expressly subordinated in right of payment to any other Indebtedness of the Company or such Guarantor, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Securities or the applicable Guarantee, as the case may be, to the same extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or such Guarantor, as the case may be. For purposes of the foregoing, no Indebtedness shall be deemed to be subordinated in right of payment to any other Indebtedness of the Company or any Guarantor solely by virtue of such Indebtedness being unsecured or by virtue of the fact that the holders of such Indebtedness have entered into one or more intercreditor agreements giving one or more of such holders priority over the other holders in the collateral held by them.

(e) For purposes of determining compliance with any U.S. dollar restriction on the incurrence of Indebtedness where the Indebtedness incurred is denominated in a different currency, the amount of such Indebtedness shall be the U.S. Dollar Equivalent determined on the date of the incurrence of such Indebtedness; provided , however , that if any such Indebtedness denominated in a different currency is subject to a Currency Agreement with respect to U.S. dollars covering all principal, premium, if any, and interest payable on such Indebtedness, the amount of such Indebtedness expressed in U.S. dollars shall be as provided in such Currency Agreement. The principal amount of any Refinancing Indebtedness incurred in the same currency as the Indebtedness being Refinanced shall be the U.S. Dollar Equivalent of the Indebtedness Refinanced, except to the extent that (1) such U.S. Dollar Equivalent was determined based on a Currency Agreement, in which case the Refinancing Indebtedness shall be determined in accordance with the preceding sentence, and (2) the principal amount of the Refinancing Indebtedness exceeds the principal amount of the Indebtedness being Refinanced, in which case the U.S. Dollar Equivalent of such excess shall be determined on the date such Refinancing Indebtedness is incurred.

43

SECTION 4.04. Limitation on Restricted Payments. (a) The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, make a Restricted Payment if at the time of such Restricted Payment or immediately after giving effect thereto:

(1) a Default or an Event of Default shall have occurred and be continuing (or would result therefrom);

(2) the Company is not able to incur at least $1.00 of additional Indebtedness (other than Indebtedness permitted to be incurred under Section 4.03(b)) in compliance with Section 4.03; or

Upon receiving notice of the Net Proceeds Offer, Holders may elect to tender their Securities in whole or in part in minimum denominations of $2,000 principal amount or any greater integral multiple of $1,000 thereof in exchange for cash. To the extent Holders properly tender Securities and holders of Other Pari Passu Lien Obligations properly tender such Other Pari Passu Lien Obligations in an amount exceeding the Net ABL Proceeds Offer Amount, the tendered Securities and Other Pari Passu Lien Obligations will be purchased on a pro rata basis based on the aggregate amounts of Securities and Other Pari Passu Lien Obligations tendered (and the Trustee shall select the tendered Securities of tendering Holders on a pro rata basis based on the amount of the Securities tendered). A Net ABL Proceeds Offer shall remain open for a period of 20 business days or such longer period as may be required by law. If any Net Cash Proceeds remain after the consummation of any Net ABL Proceeds Offer, the Company may use those Net Cash Proceeds for any purpose not otherwise prohibited by this Indenture. Upon completion of each Net ABL Proceeds Offer, the amount of Net Cash Proceeds covered by this clause (B) will be reset at zero.

In the event of any such sale (or a sale of assets that includes any combination of Non-ABL Priority Collateral and ABL Priority Collateral), the proceeds received by the Company and the Restricted Subsidiaries in respect of such sale shall be allocated to the Non-ABL Priority Collateral and ABL Priority Collateral as described in the Intercreditor Agreement. In addition, for purposes of this Section 4.06, any sale by the Company or any Restricted Subsidiary of the Capital Stock of any Person that owns only ABL Priority Collateral will not be subject to Section 4.06(I), but rather will be subject to Section 4.06(II).

(V) (1) Not later than the date upon which a copy of a Net Proceeds Offer or a Net ABL Proceeds Offer, as applicable, is delivered to the Trustee as provided in Sections 4.06(I)(e) or 4.06(II)(e), respectively, the Company shall deliver to the Trustee an Officers’ Certificate as to (A) the Net Proceeds Offer Amount or the Net ABL Proceeds Offer Amount, as applicable, including information as to any Other Pari Passu Lien Obligations included in the Net Proceeds Offer or Net ABL Proceeds Offer, (B) the allocation of the Net Cash Proceeds from the Asset Sale pursuant to which such Net Proceeds Offer or Net ABL Proceeds Offer is being made and (C) the compliance of such allocation with the provisions of Section 4.06(I) or 4.06(II), as applicable. On such date, the Company shall also irrevocably deposit with the Trustee or with the Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) an amount equal to the Net Proceeds Offer Amount or the Net ABL Proceeds Offer Amount, as applicable, to be held for payment in accordance with the provisions of this Section 4.06(V). If the Net Proceeds Offer or Net ABL Proceeds Offer includes Other Pari Passu Lien Obligations, the deposit described in the preceding sentence may be made with any other paying agent pursuant to arrangements satisfactory to the Trustee.

The Trustee shall, on the date required by the applicable Net Proceeds Offer or Net ABL Proceeds Offer (such date, the “Offer Payment Date”), mail or deliver payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of the Securities delivered by the Company to the Trustee is less than the Net Proceeds Offer Amount or the Net ABL Proceeds Offer Amount, as applicable, applicable to the Securities, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with this Section 4.06.

Holders whose Securities are purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered.

(3) At the time the Company delivers Securities to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’ Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section. A Security shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering Holder.

(VI) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Securities pursuant to a Net Proceeds Offer.

SECTION 4.10. Limitation on Liens. (a) The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or permit or suffer to exist any Liens (“Initial Lien”) of any kind against or upon any property or assets of the Company or any of its Restricted Subsidiaries whether owned on the Issue Date or acquired after the Issue Date, or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom other than:

(1) in the case of the Notes Priority Collateral, any Initial Lien if (a) such Initial Lien expressly ranks junior to the first-priority security interest intended to be created in favor of the Notes Collateral Agent for the benefit of the Trustee, the Notes Collateral Agent, the Holders of Securities and the holders of any future Other Pari Passu Lien Obligations (if any), provided that the terms of such junior interest will be no more favorable to the beneficiaries thereof than the terms contained in the Intercreditor Agreement, or (b) such Initial Lien is a Permitted Collateral Lien;

58

(2) in the case of the ABL Priority Collateral, any Initial Lien if (a) the Securities and the Guarantees are equally and ratably secured on a second-priority basis by such ABL Priority Collateral until such time as such Initial Lien is released or (b) such Initial Lien is a Permitted Lien; and

(3) in the case of any other asset or property, any Initial Lien if (a) the Securities and the Guarantees are equally and ratably secured with (or on a senior basis to, in the case such Initial Lien secures any Subordinated Indebtedness) the obligations secured by such Initial Lien or (b) such Initial Lien is a Permitted Lien.

(b) Any Lien created for the benefit of the Holders of Securities pursuant to Section 4.10(a)(2) or (3) will be automatically and unconditionally released and discharged upon the release and discharge of each Initial Lien to which it relates, which release and discharge in the case of any sale of any asset or property shall not affect any Lien that the Notes Collateral Agent may have on the proceeds from such sale.

(c) Any reference to a Permitted Collateral Lien or a Permitted Lien is not intended to subordinate or postpone, and shall not be interpreted as subordinating or postponing, or as any agreement to subordinate or postpone, any Lien in favor of the Notes Collateral Agent in respect of the Notes Priority Collateral or the ABL Priority Collateral.

(d) With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest or fees, any accretion of accreted value, any amortization of original issue discount, any payment of interest in the form of additional Indebtedness containing the same terms or in the form of Qualified Capital Stock of the Company, any payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class or any accretion of original issue discount or liquidation preference and any increase in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness.

59

(c) the Company applies the proceeds of such transaction in compliance with Section 4.06.

SECTION 4.12. Future Guarantors. The Company shall not permit any of its Wholly Owned Subsidiaries that are organized in the United States or any State thereof or the District of Columbia, directly or indirectly, by way of the pledge of any intercompany note or otherwise, to incur any Indebtedness or assume, guarantee or in any other manner become liable with respect to Indebtedness of the Company or any Guarantor, including under the Credit Agreement, unless such Restricted Subsidiary is a Guarantor or contemporaneously executes and delivers to the Trustee a Guarantee Agreement pursuant to which such Restricted Subsidiary shall guarantee payment of the Securities on a senior secured basis on the same terms and conditions as those set forth in this Indenture and applicable to the other Guarantors and delivers to the Trustee joinders or supplements, as applicable, in form and substance reasonably satisfactory to the Trustee, to the Security Documents and Intercreditor Agreement, as well as an Opinion of Counsel that such Guarantee Agreement, joinders and supplements, as applicable, have been duly authorized, executed and delivered by such Restricted Subsidiary and constitute a legal, valid, binding and enforceable obligation of such Restricted Subsidiary.

Notwithstanding the foregoing, any such Guarantee by a Restricted Subsidiary of the Securities shall provide by its terms that it shall be automatically and unconditionally released and discharged, as described under Article 10 of this Indenture.

SECTION 4.13. Payments for Consent. The Company shall not, and shall 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 Securities for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Securities unless such consideration is offered to be paid and is paid to all Holders of the Securities that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

60

SECTION 4.14. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. If they do, the certificate shall describe the Default, its status and what action the Company is taking or proposes to take with respect thereto. The Company also shall comply with TIA § 314(a)(4).

SECTION 4.15. Information Regarding Collateral . (a) The Company shall furnish to the Notes Collateral Agent, with respect to the Company or any Guarantor, written notice within five business days of any change in such Person’s (i) organizational name, (ii) jurisdiction of organization or formation, (iii) identity or organizational structure or (iv) organizational identification number. The Company and the Guarantors shall agree to make all filings under the Uniform Commercial Code or equivalent statutes or otherwise that are required by applicable law in order for the Notes Collateral Agent to continue at all times following such change to have a valid, legal and perfected security interest in all the Collateral.

(b) Each year, at the time of delivery of annual financial statements in accordance with Section 4.02 of this Indenture, the Company shall deliver to the Trustee and the Notes Collateral Agent a certificate of a financial officer setting forth the information required pursuant to the perfection certificate delivered on the Issue Date or confirming there has been no change in such information since the date of the prior delivered perfection certificate.

(c) The Company shall (i) furnish to the Trustee and the Notes Collateral Agent prompt written notice of any casualty or other insured damage to any material portion of the Collateral or the commencement of any action or proceeding for the taking of any material portion of the Collateral under power of eminent domain or by condemnation or similar proceeding and (ii) ensure that the net proceeds of any such event (whether in the form of insurance proceeds, condemnation awards or otherwise) are collected and applied in accordance with the applicable provisions of the Security Documents.

SECTION 4.16. Further Assurances and After-Acquired Property . (a) Subject to the applicable limitations set forth in the Security Documents and this Indenture (including with respect to Excluded Assets), the Company and the Guarantors shall execute any and all further documents, financing statements, agreements and instruments, and take all further action that may be required under applicable law, or that the Notes Collateral Agent may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security interests created or intended to be created by the Security Documents in the Collateral. Subject to the applicable limitations set forth in the Security Documents and this Indenture (including with respect to Excluded Assets), if the Company or a Guarantor acquires property that is not automatically subject to a perfected security interest under the Security Documents and such property constitutes or would constitute Collateral (including any asset of the Company or a Guarantor that becomes Collateral subsequent to the Issue Date as a result of such asset ceasing to be an Excluded Asset) or an entity becomes a Guarantor, then the Company or such Guarantor shall, within 90 days after acquisition or 90 days after the date such asset ceases to be an Excluded Asset (with respect to real property and related fixtures) (in each case, or such longer period as the Notes Collateral Agent may agree in its sole discretion) and as soon as practicable (with respect to other assets), provide a security interest over such property (or, in the case of a new Guarantor, its assets that would constitute Collateral under the Security Documents) in favor of the Notes Collateral Agent and deliver certain joinder agreements or supplements as required by this Indenture and the Security Documents. Notwithstanding the foregoing, until the Discharge of ABL Obligations, the Company and the Guarantors shall only be required to comply with the foregoing requirements with respect to any ABL Priority Collateral to the extent that such ABL Priority Collateral is concurrently being pledged to secure the obligations under the Lenders Debt.

61

(b) In addition, the Company and the Guarantors shall:

(1) on or before the date that is 90 days after the Issue Date, deliver to the Notes Collateral Agent (A) counterparts of a mortgage with respect to all Issue Date Real Property Collateral, duly executed and delivered by the Company or the Guarantor, as applicable, which owns such real property, (B) a policy or policies of title insurance (or pro forma therefor) issued by a nationally recognized title insurance company insuring the Lien of such mortgage as a valid and enforceable Lien on a first-priority basis on the mortgaged property described therein, free of any other Liens except Permitted Collateral Liens, together with customary endorsements, coinsurance and reinsurance, (C) if such mortgaged property is located in an area determined by the Federal Emergency Management Agency to have special flood hazards, evidence of such flood insurance as may be required under applicable law, including Regulation H of the Board of Governors, and (D) such surveys, abstracts, appraisals, legal opinions and other documents as the Notes Collateral Agent may reasonably request with respect to any such mortgage or mortgaged property; and

(2) on or before the date that is 90 days after the Issue Date, deliver to the Notes Collateral Agent control agreements and related pledge agreements in respect of deposit accounts and securities accounts (if any) required pursuant to the Security Documents.

SECTION 4.17. Further Instruments and Acts. Upon request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

(1) either:

(a) the Company shall be the surviving or continuing corporation; or

(b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the Company and of the Company’s Restricted Subsidiaries substantially as an entirety (the “Surviving Entity”) (i) shall be a corporation organized and validly existing under the laws of the United States or any State thereof or the District of Columbia, and (ii) shall expressly assume, by supplemental indenture or other documents or instruments (in each case, in form and substance satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of, and premium, if any, and interest on all of the Securities and the performance of every covenant of the Securities, this Indenture and the Registration Rights Agreement on the part of the Company to be performed or observed, and all obligations of the Company under the Security Documents and Intercreditor Agreement;

(2) immediately after giving effect to such transaction and the assumption contemplated by clause (1)(B)(ii) above (including giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction), the Company or such Surviving Entity, as the case may be, shall be able to incur at least $1.00 of additional Indebtedness (other than Indebtedness permitted to be incurred under Section 4.03(b)) pursuant to Section 4.03;

(3) immediately before and immediately after giving effect to such transaction and the assumption contemplated by clause (1)(B)(ii) above (including, without limitation, giving effect to any Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred or be continuing;

(5) to the extent any assets of the Person which is consolidated with or merged with or into the Surviving Entity are assets of the type which would constitute Collateral under the Security Documents, the Surviving Entity shall take such action as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the Security Documents in the manner and to the extent required in this Indenture or any of the Security Documents and shall take all reasonably necessary action so that such Lien is perfected to the extent required by this Indenture and the Security Documents; and

(6) the Collateral owned by or transferred to the Surviving Entity shall: (a) continue to constitute Collateral under this Indenture and the Security Documents, (b) be subject to the Lien in favor of the Notes Collateral Agent for the benefit of the Trustee and the Holders of Securities and (c) not be subject to any Lien other than Permitted Collateral Liens or Permitted Liens, as the case may be, and other Liens permitted under Section 4.10.

For purposes of this Section 5.01, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Company, the Capital Stock of which constitutes all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

Notwithstanding the foregoing clauses (1), (2), (3), (4) and (5), the Company may merge with an Affiliate that is a Person that has no material assets or liabilities and which was organized solely for the purpose of reorganizing the Company in another jurisdiction in the United States, any State thereof or the District of Columbia so long as the amount of Indebtedness of the Company is not increased thereby.

Upon any consolidation, combination or merger or any transfer of all or substantially all of the assets of the Company in accordance with this Section 5.01 in which the Company is not the surviving or continuing corporation, the Surviving Entity shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, the Security Documents and the Securities with the same effect as if such Surviving Entity had been named as such.

64

(b) Each Guarantor (other than any Guarantor whose Guarantee is to be released in accordance with the terms of the Guarantee and this Indenture in connection with any transaction complying with Section 4.06) shall not, and the Company shall not cause or permit any Guarantor to, consolidate with or merge with or into any Person other than the Company or any other Guarantor, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of such Guarantor’s assets whether as an entirety or substantially as an entirety to any Person other than the Company or any other Guarantor unless:

(1) the entity formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any State thereof or the District of Columbia;

(5) the Collateral owned by or transferred to such entity shall (a) continue to constitute Collateral under this Indenture and the Security Documents, (b) be subject to the Lien favor of the Notes Collateral Agent for the benefit of the Trustee and the Holders of Securities and (c) not be subject to any Lien other than Permitted Liens and other Liens permitted under Section 4.10.

65

Article 6

66

(7) one or more judgments or decrees for the payment of money in an aggregate amount in excess of $25,000,000 (net of any amounts that are covered by insurance issued by a reputable and creditworthy insurance company) shall have been rendered against the Company, any Guarantor or any Significant Subsidiary of the Company and such judgments or decrees remain undischarged, unpaid or unstayed for a period of 60 days after such judgment or judgments become final and non-appealable;

(8) the Company, any Guarantor or any Significant Subsidiary of the Company pursuant to or within the meaning of any Bankruptcy Law:

(a) commences a voluntary case;

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

(c) consents to the appointment of a Custodian of it or for any substantial part of its property; or

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

or takes any comparable action under any foreign laws relating to insolvency;

(9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a) is for relief against the Company, any Guarantor or any Significant Subsidiary of the Company in an involuntary case;

(b) appoints a Custodian of the Company, any Guarantor or any Significant Subsidiary of the Company or for any substantial part of its property; or

(c) orders the winding up or liquidation of the Company, the Guarantor or any Significant Subsidiary of the Company;

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days;

(10) any Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Guarantee), is declared to be null and void and unenforceable by any final and non-appealable judgment or decree, or any Guarantor denies or disaffirms its liability under its Guarantee; or

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

The term “Bankruptcy Law” means Title 11, United States Code , or any similar Federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

A Default under clauses (4) or (5) is not an Event of Default until the Trustee or the holders of at least 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default”.

The Company shall deliver an Officers’ Certificate to the Trustee promptly upon any such Officers obtaining knowledge of any Default or Event of Default ( provided that such Officers shall provide such certification at least annually whether or not such Officers have obtained knowledge of any Default or Event of Default) that has occurred and, if applicable, describe such Default or Event of Default and the status thereof.

SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(8) or (9) with respect to the Company) shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Securities may declare the principal of and accrued interest on all the Securities to be due and payable by notice in writing to the Company and the Trustee specifying the respective Event of Default and that it is a “Notice of Acceleration” and the same shall become immediately due and payable. If an Event of Default specified in Section 6.01(8) or (9) with respect to the Company occurs and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding 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. At any time after a declaration of acceleration with respect to the Securities as described above, the Holders of a majority in principal amount of the outstanding Securities may rescind and cancel such declaration and its consequences:

68

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

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

(c) 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;

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

(e) in the event of the cure or waiver of an Event of Default of the type described in Section 6.01(6), 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.

SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceedings, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in principal amount of the outstanding Securities may waive any existing Default or Event of Default under this Indenture, and its consequences, except a Default in the payment of the principal of or interest on any Security. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee and the Notes Collateral Agent or of exercising any trust or power conferred on the Trustee or the Notes Collateral Agent, as applicable. However, the Trustee and the Notes Collateral Agent may refuse to follow any direction that conflicts with law or this Indenture, the Securities and the Security Documents or, subject to Section 7.01, that the Trustee or the Notes Collateral Agent determines is unduly prejudicial to the rights of other Holders or would involve the Trustee or the Notes Collateral Agent, as applicable in personal liability; provided , however , that the Trustee and the Notes Collateral Agent, as applicable may take any other action deemed proper by the Trustee or the Notes Collateral Agent, as applicable that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee or the Notes Collateral Agent shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

SECTION 6.06. Limitation on Suits. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless:

(1) the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

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

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

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

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

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. In the event that the Definitive Securities are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Security to issue such Definitive Securities to such beneficial owner of its nominee, the Company expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial holder’s Securities as if such Definitive Securities had been issued.

70

Notwithstanding the foregoing, in no event may any Holder enforce any Lien of the Notes Collateral Agent pursuant to the Security Documents.

SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07.

Priorities. Subject to the terms of the Security Documents and the Intercreditor Agreement with respect to any proceeds of Collateral, if the Trustee or Notes Collateral Agent collects any money or property pursuant to this Article 6, it shall pay out the money or property, together with other amounts held by the Trustee under this Indenture, in the following order:

FIRST: to the Trustee for amounts due under Section 7.07 and to the Notes Collateral Agent for amounts due under Article 11 or under any Security Document;

SECOND: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

71

THIRD: to the Company, or to the extent the Trustee collects any amount for any Guarantor, to such Guarantor.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section. At least 15 days before such record date, the Company shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid.

SECTION 6.10. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Securities.

SECTION 6.11. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

Article 7

Trustee

SECTION 7.01. Duties of Trustee. (a) During the existence of an Event of Default, the Trustee shall exercise such rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(1) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee shall perform only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

72

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which are specifically required to be furnished to the Trustee pursuant to this Indenture, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

(1) this paragraph does not limit the effect of paragraph (b) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was grossly negligent in ascertaining the pertinent facts; and

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(h) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the provisions of the TIA.

SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Securities, the Security Documents or the Intercreditor Agreement, and it shall not be accountable for the Company’s use of the proceeds from the Securities or of any money paid to the Company at the Company’s direction pursuant to the provisions of this Indenture, it shall not be responsible for the use or application of any money received by any agent other than the Trustee, and it shall not be responsible for any statement or recital in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

SECTION 7.05. Notice of Defaults. If a Default occurs, is continuing and is known to the Trustee, the Trustee shall mail to each Securityholder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Security, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is not opposed to the interests of the Securityholders. The Trustee shall not be deemed to know of any Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee and such notice references this Indenture.

SECTION 7.06. Reports by Trustee to Holders. If required by Section 313(a) of the TIA, as promptly as practicable after each June 30 beginning with the June 30 following the date of this Indenture, and in any event prior to August 30 in each year, the Trustee shall mail to each Securityholder a brief report dated as of June 30 that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b).

74

A copy of each report at the time of its mailing to Securityholders shall be filed with the Commission and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable disbursements, advances, and out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee and hold the Trustee harmless against any and all loss, liability or expense (including attorneys’ fees) incurred by it in connection with the administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own wilful misconduct, gross negligence or bad faith.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Company’s payment obligations pursuant to this Section shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(8) or (9) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company.

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

(2) the Trustee is adjudged bankrupt or insolvent;

(3) a receiver or other public officer takes charge of the Trustee or its property; or

(4) the Trustee otherwise becomes incapable of acting.

75

If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the outstanding Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

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

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

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

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

SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

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

76

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided , however , that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

SECTION 7.12. Security Documents; Intercreditor Agreement . By their acceptance of the Securities, the Holders hereby authorize and direct the Trustee and the Notes Collateral Agent, as the case may be, to execute and deliver the Intercreditor Agreement and the Security Documents in which the Trustee or the Notes Collateral Agent, as applicable, is named as a party, including any Security Documents executed after the Issue Date. It is hereby expressly acknowledged and agreed that, in doing so, the Trustee and the Notes Collateral Agent are not responsible for the terms or contents of such agreements, or for the validity or enforceability thereof, or the sufficiency thereof for any purpose. Whether or not so expressly stated therein, in entering into, or taking (or forbearing from) any action under or pursuant to, the Intercreditor Agreement or any other Security Document, the Trustee and the Notes Collateral Agent each shall have all the rights, immunities, indemnities and other protections granted to it under this Indenture (in addition to those that may be granted to it under the terms of such other agreement or agreements).

Article 8

(1) either:

(a) all the Securities theretofore authenticated and delivered (except lost, stolen or destroyed Securities which have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation; or

The Company may exercise Legal Defeasance notwithstanding its prior exercise of Covenant Defeasance.

If the Company exercises Legal Defeasance, payment of the Securities may not be accelerated because of an Event of Default with respect thereto. If the Company exercises Covenant Defeasance, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in the case of Sections 6.01(8) and (9), with respect only to Significant Subsidiaries and Guarantors) or because of the failure of the Company to comply with Section 5.01(a)(2). If the Company exercises Legal Defeasance or Covenant Defeasance, each Guarantor, if any, shall be released from all its obligations with respect to its Guarantee.

After an amendment under this Section becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of such amendment.

SECTION 9.02. With Consent of Holders. The Company, the Guarantors and the Trustee and Collateral Agent may amend the Note Documents with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for such Securities) and any past default or compliance with any provisions may also be waived with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding. However, without the consent of each Holder affected thereby, no amendment may:

(1) reduce the principal amount of Securities whose Holders must consent to an amendment;

83

(2) reduce the rate of or change or have the effect of changing the time for payment of interest, including defaulted interest, on any Security;

(3) reduce the principal of or change or have the effect of changing the fixed maturity of any Security, or change the date on which any Security may be subject to redemption or reduce the redemption price therefor;

(4) change the provisions applicable to the redemption of any Security contained in Article 3 hereto or paragraph 5 of the Securities;

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

(10) make any change in the Intercreditor Agreement or in the provisions of this Indenture or any Security Document dealing with the application of proceeds of the Collateral in a manner which adversely affects the Holders.

In addition, without the consent of the Holders of at least two-thirds in principal amount of the Securities then outstanding, no amendment, supplement or waiver may release any Collateral from the Liens of the Security Documents other than in accordance with this Indenture, the Intercreditor Agreement and the Security Documents.

If Holders of at least two-thirds in principal amount of the Securities then outstanding consent to any release of any Collateral from the Liens of the Security Documents other than a release in accordance with this Indenture, the Intercreditor Agreement and the Security Documents, the Notes Collateral Agent will be entitled to vote the total principal amount of the Securities then outstanding as a block in respect of any vote required for such release under the Security Documents.

84

The consent of the Holders is not necessary under this Section to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment.

After an amendment under this Section becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of such amendment.

SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes effective upon the execution of such amendment or waiver by the Trustee.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Securityholders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 9.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

Article 10

Guarantees

SECTION 10.01. Guarantees. Each Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (a) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture, the Security Documents, the Intercreditor Agreement and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Guarantor and that such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation.

Each Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Guarantor) under this Indenture, the Securities, the Security Documents, the Intercreditor Agreement or any other agreement or otherwise; (2) any extension or renewal of any thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities, the Security Documents, the Intercreditor Agreement or any other agreement; (4) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 10.06, any change in the ownership of such Guarantor.

Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

86

Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities, the Security Documents, the Intercreditor Agreement or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

Each Guarantor agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Guarantor’s Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section.

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section.

SECTION 10.02. Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

87

SECTION 10.03. Successors and Assigns. This Article 10 shall be binding upon each Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.05. Modification. No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.06. Release of Guarantor. A Guarantor shall be released from its obligations under this Article 10 (other than any obligation that may have arisen under Section 10.07):

(1) in the event all of the Capital Stock of a Guarantor is sold or spun-off by the Company; provided that such sale or spin-off complies with Section 4.06 and in connection therewith the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions provided for in this Indenture relating to such transaction have been complied with;

(2) upon the designation by the Company of such Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with the provisions of this Indenture;

(3) upon the release or discharge of any Guarantee or Indebtedness that resulted in the creation after the Issue Date of the Guarantee pursuant to Section 4.12; or

(4) the Company’s exercise of Legal Defeasance or Covenant Defeasance as described under Article 8 or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture.

88

At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release.

Upon the release of a Guarantor from its Guarantee, such Guarantor will also be automatically and unconditionally released from its obligations under the Security Documents.

SECTION 10.07. Contribution. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

Article 11

Collateral

SECTION 11.01. Collateral and Security Documents . The due and punctual payment of the principal of and interest on the Securities and the Guarantees when and as the same shall be due and payable, whether on an interest payment date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and interest on the Securities and the Guarantees and performance of all other Obligations of the Company and the Guarantors to the Securityholder Secured Parties under this Indenture, the Securities, the Guarantees, the Intercreditor Agreement and the Security Documents, according to the terms hereunder or thereunder, shall be secured as provided in the Security Documents, which define the terms of the Liens that secure the Obligations, subject to the terms of the Intercreditor Agreement. The Trustee, the Company and the Guarantors hereby acknowledge and agree that the Notes Collateral Agent holds the Collateral in trust for the benefit of the Securityholder Secured Parties pursuant to the terms of the Security Documents and the Intercreditor Agreement. Each Holder, by accepting a Security, consents and agrees to the terms of the Security Documents (including the provisions providing for the possession, use, release and foreclosure of Collateral) and the Intercreditor Agreement as the same may be in effect or may be amended from time to time in accordance with their terms and this Indenture and the Intercreditor Agreement, and authorizes and directs the Notes Collateral Agent to enter into the Security Documents and the Intercreditor Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith. The Company shall deliver to the Notes Collateral Agent copies of all documents required to be filed pursuant to the Security Documents, and shall do or cause to be done all such acts and things as may be reasonably required by the next sentence of this Section 11.01, to assure and confirm to the Notes Collateral Agent the first-priority security interest in the Notes Priority Collateral and the second-priority lien in the ABL Priority Collateral contemplated hereby, by the Security Documents or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Securities secured hereby, according to the intent and purposes herein expressed. The Company shall, and shall cause its Subsidiaries to, take any and all actions and make all filings, registrations and recordations (including the filing of Uniform Commercial Code financing statements, continuation statements and amendments thereto) in all such jurisdictions reasonably required to cause the Security Documents to create, perfect and maintain, as security for the Obligations of the Company and the Guarantors to the Securityholder Secured Parties under this Indenture, the Securities, the Guarantees, the Intercreditor Agreement and the Security Documents, a valid and enforceable perfected Lien and security interest in and on all of the Collateral (subject to the terms of the Intercreditor Agreement and the Security Documents), in favor of the Notes Collateral Agent for the benefit of the Securityholder Secured Parties subject to no Liens other than Liens permitted pursuant to this Indenture.

89

SECTION 11.02. Non-Impairment of Liens . Any release of Collateral permitted by Section 11.03 shall be deemed not to impair the Liens under this Indenture and the Security Documents in contravention thereof.

(a) Subject to Section 11.03(b), Collateral may be released from the Lien and security interest created by the Security Documents at any time or from time to time in accordance with the provisions of the Security Documents, the Intercreditor Agreement and this Indenture. Notwithstanding anything to the contrary in any Security Document, the Liens on Collateral securing the Securities shall be immediately released with respect to the relevant Collateral under any one or more of the following circumstances:

(1) to enable the disposition of such property or assets, including Capital Stock (other than to the Company or a Guarantor) to the extent not prohibited by Section 4.06;

(2) in the case of a Guarantor that is released from its Guarantee, the release of the property and assets of such Guarantor;

(3) with respect to Collateral that is Capital Stock, upon the dissolution or liquidation of the issuer of that Capital Stock that is not prohibited by this Indenture or upon the release of a Guarantor that has pledged such Capital Stock;

(4) pursuant to an amendment, supplement or waiver in accordance with Article 9;

(5) if the Securities have been discharged or defeased pursuant to Article 8; or

90

(b) The second-priority Lien on the ABL Priority Collateral securing the Securities and the Guarantees will terminate and be released automatically if the first-priority Liens on the ABL Priority Collateral are released by the Bank Collateral Agent (unless, at the time of such release of such first-priority Liens, an Event of Default shall have occurred and be continuing), other than (i) in connection with a Discharge of ABL Obligations under the Credit Agreement or (ii) to the extent prohibited under this Indenture. Notwithstanding the existence of an Event of Default, the second-priority Liens on the ABL Priority Collateral securing the Securities and the Guarantees shall also terminate and be released automatically to the extent the first-priority Liens on the ABL Priority Collateral are released by the Bank Collateral Agent in connection with a sale, transfer or disposition of ABL Priority Collateral that occurs in connection with the foreclosure of, or other exercise of remedies with respect to, ABL Priority Collateral by the Bank Collateral Agent (except with respect to any proceeds of such sale, transfer or disposition that remain after satisfaction in full of the Lenders Debt).

(c) With respect to any release of Collateral permitted by this Section 11.03, upon receipt of a written request from the Company and supported by an Officers’ Certificate stating that all conditions precedent under this Indenture and the Security Documents and the Intercreditor Agreement, if any, to such release have been met and that it is proper for the Trustee or Notes Collateral Agent to execute and deliver the documents requested by the Company in connection with such release, and any necessary or proper instruments of termination, satisfaction or release prepared by the Company, the Trustee shall, or shall cause the Notes Collateral Agent to, execute, deliver or acknowledge (at the Company’s expense) such instruments or releases to evidence the release of any Collateral permitted to be released pursuant to this Indenture or the Security Documents or the Intercreditor Agreement. Neither the Trustee nor the Notes Collateral Agent shall be liable for any such release undertaken in reliance upon any such Officers’ Certificate, and notwithstanding any term hereof or in any Security Document or in the Intercreditor Agreement to the contrary, the Trustee and the Notes Collateral Agent shall not be under any obligation to release any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction or termination, unless and until it receives such Officers’ Certificate.

SECTION 11.04. Suits to Protect the Collateral . (a) Subject to the provisions of Article 7, the Security Documents and the Intercreditor Agreement, the Trustee, without the consent of the Holders, on behalf of the Holders, may or may direct the Notes Collateral Agent to take all actions it determines in order to:

(1) enforce any of the terms of the Security Documents; and

(2) collect and receive any and all amounts payable in respect of the Obligations hereunder.

91

(b) Subject to the provisions of the Security Documents and the Intercreditor Agreement, the Trustee and the Notes Collateral Agent shall have power to institute and to maintain such suits and proceedings as the Trustee may determine to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Security Documents or this Indenture, and such suits and proceedings as the Trustee may determine to preserve or protect its interests and the interests of the Holders in the Collateral. Nothing in this Section 11.04 shall be considered to impose any such duty or obligation to act on the part of the Trustee or the Notes Collateral Agent.

SECTION 11.05. Authorization of Receipt of Funds by the Trustee Under the Security Documents . Subject to the provisions of the Intercreditor Agreement, the Trustee is authorized to receive any funds for the benefit of the Holders distributed under the Security Documents, and to make further distributions of such funds to the Holders according to the provisions of this Indenture.

SECTION 11.06. Purchaser Protected . In no event shall any purchaser in good faith of any property purported to be released hereunder be bound to ascertain the authority of the Notes Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or rights permitted by this Article 11 to be sold be under any obligation to ascertain or inquire into the authority of the Company or the applicable Guarantor to make any such sale or other transfer.

SECTION 11.07. Powers Exercisable by Receiver or Trustee . In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Company or a Guarantor with respect to the release, sale or other disposition of such property may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or a Guarantor or of any Officer or Officers thereof required by the provisions of this Article 11; and if the Trustee shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.

SECTION 11.08. Release Upon Termination of the Company’s Obligations . In the event that the Company delivers to the Trustee an Officers’ Certificate certifying that (i) payment in full of the principal of, together with accrued and unpaid interest on, the Securities and all other Obligations under this Indenture, the Securities, the Guarantees and the Security Documents that are due and payable at or prior to the time such principal, together with accrued and unpaid interest, are paid (other than contingent indemnification obligations that, pursuant to the terms of this Indenture and the Security Documents, survive the termination thereof) or (ii) the Company shall have exercised its Legal Defeasance option or its Covenant Defeasance option, in each case in compliance with the provisions of Article 8, and an Opinion of Counsel stating that all conditions precedent to the execution and delivery of such notice by the Trustee have been satisfied, the Trustee shall deliver to the Company and the Notes Collateral Agent a notice stating that the Trustee, on behalf of the Holders, disclaims and gives up any and all rights it has in or to the Collateral (other than with respect to funds held by the Trustee pursuant to Article 8), and any rights it has under the Security Documents, and upon receipt by the Notes Collateral Agent of such notice, the Notes Collateral Agent shall be deemed not to hold a Lien in the Collateral on behalf of the Trustee and shall do or cause to be done all acts reasonably necessary to release such Lien as soon as is reasonably practicable.

92

SECTION 11.09. Notes Collateral Agent . (a) By accepting a Security, each Holder shall be deemed to have irrevocably appointed the Notes Collateral Agent to act as its agent under the Security Documents and the Intercreditor Agreement and to have irrevocably authorized the Notes Collateral Agent to (i) perform the duties and exercise the rights, powers and discretions that are specifically given to it under the Security Documents, the Intercreditor Agreement or other documents to which it is a party, together with any other incidental rights, powers and discretions; and (ii) execute each document expressed to be executed by the Notes Collateral Agent on its behalf.

(b) The Notes Collateral Agent is authorized and empowered to appoint one or more subagents or co-collateral agents as it deems necessary or appropriate.

(c) The Notes Collateral Agent shall have all the rights and protection provided in the Note Documents as well as the rights and protections afforded to the Trustee in Sections 7.02 and 7.07; provided , however , that the Company shall not reimburse any expense or indemnify against any loss, liability or expense incurred by the Notes Collateral Agent through the Notes Collateral Agent’s own willful misconduct, gross negligence or bad faith.

(d) Subject to Section 7.01, none of the Trustee, the Notes Collateral Agent or any of their respective officers, directors, employees, attorneys or agents shall be responsible or liable for the existence, genuineness, value or protection of any Collateral, for the legality, enforceability, effectiveness or sufficiency of the Security Documents, for the creation, perfection, priority, sufficiency or protection of any Lien securing the Securities or any defect or deficiency as to any such matters.

(e) Subject to the Security Documents, except as directed by the Trustee as required or permitted by this Indenture, the Holders acknowledge that the Notes Collateral Agent shall not be obligated:

(1) to act upon directions purported to be delivered to it by any other Person;

(2) to foreclose upon or otherwise enforce any Lien securing the Securities; or

(3) to take any other action whatsoever with regard to any or all Liens securing the Securities, the Security Documents or the Collateral.

(f) In acting as Notes Collateral Agent, co-collateral agent or sub-collateral agent, the Notes Collateral Agent, each co-collateral agent and each sub-collateral agent may rely upon and enforce each and all of the rights, powers, immunities, indemnities and benefits of the Trustee under Article 7.

93

SECTION 11.10. Designations . Except as provided in the next sentence, for purposes of the provisions hereof and the Intercreditor Agreement requiring the Company to designate Indebtedness for the purposes of the terms “Lenders Debt” and “Other Pari Passu Lien Obligations” or any other such designations hereunder or under the Intercreditor Agreement, any such designation shall be sufficient if the relevant designation is set forth in writing, signed on behalf of the Company by an Officer and delivered to the Trustee, the Notes Collateral Agent and the Bank Collateral Agent. For all purposes hereof and the Intercreditor Agreement, the Company hereby designates the Obligations pursuant to the Credit Agreement as “Lenders Debt.”

SECTION 11.11. Limitation on Stock Collateral . (a) The Capital Stock and other securities of a Subsidiary of the Company that are owned by the Company or any Guarantor will constitute Notes Priority Collateral only to the extent that such Capital Stock and other securities can secure the Securities without Rule 3-16 of Regulation S-X under the Securities Act (or any other U.S. federal law, rule or regulation) requiring separate financial statements of such Subsidiary to be filed with the SEC (or any other U.S. federal governmental agency). In the event that Rule 3-16 of Regulation S-X under the Securities Act requires or is amended, modified or interpreted by the SEC to require (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would require) the filing with the SEC (or any other governmental agency) of separate financial statements of any Subsidiary due to the fact that such Subsidiary’s Capital Stock and other securities secure the Securities, then the Capital Stock and other securities of such Subsidiary shall automatically be deemed not to be part of the Notes Priority Collateral (but only to the extent necessary to not be subject to such requirement). In such event, the Security Documents may be amended or modified, without the consent of any Holder of Securities, to the extent necessary to release the first-priority security interests in the Capital Stock and other securities that are so deemed to no longer constitute part of the Notes Priority Collateral.

(b) In the event that Rule 3-16 of Regulation S-X under the Securities Act is amended, modified or interpreted by the SEC to permit (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would permit) such Subsidiary’s Capital Stock and other securities to secure the Securities in excess of the amount then pledged without the filing with the SEC (or any other U.S. federal governmental agency) of separate financial statements of such Subsidiary, then the Capital Stock and other securities of such Subsidiary shall automatically be deemed to be a part of the Notes Priority Collateral (but only to the extent necessary to not be subject to any such financial statement requirement). In such event, the Security Documents may be amended or modified, without the consent of the Trustee, the Notes Collateral Agent, any Holder of Securities or holder of Other Pari Passu Lien Obligations, to the extent necessary to subject to the Liens under the Security Documents such additional Capital Stock and other securities.

7.75% Senior Secured Note Due 2019

1. Interest

LSB Industries, Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided , however , that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration default occurs up to a maximum additional interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. The Company will pay interest semiannually in arrears on February 1 and August 1 of each year, commencing February 1, 2014. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the date of issuance. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful.

2. Method of Payment

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 15 or July 15 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to the Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depository. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) at the office of the Paying Agent, except that, at the option of the Company, payment of interest may be made by mailing a check to the registered address of each Holder thereof; provided , however , that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar

Initially, UMB Bank, n.a., a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice to Holders. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4. Indenture

The Company issued the Securities under an Indenture dated as of August 7, 2013 (the “Indenture”), among the Company, the Guarantors, the Trustee and the Notes Collateral Agent. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. To the extent any provision of this Security conflicts with express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

The Securities are senior secured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; issue or sell capital stock of subsidiaries; engage in transactions with affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of subsidiaries; consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries; and engage in sale/leaseback transactions. These covenants are subject to important exceptions and qualifications.

5. Optional Redemption

Except as described below, the Securities shall not be redeemable before August 1, 2016. On or after such date, the Company shall be entitled to redeem the Securities at its option, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as percentages of the principal amount thereof), plus accrued and unpaid interest to the 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), if redeemed during the twelve-month period commencing on August 1 of the year set forth below:

6

In addition, at any time, or from time to time, on or prior to August 1, 2016, the Company shall be entitled, at its option, to use the net cash proceeds of one or more Public Equity Offerings to redeem up to 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) issued under the Indenture at a redemption price of 107.75% of the principal amount thereof plus accrued and unpaid interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that:

(1) at least 65% of the aggregate principal amount of Securities (which includes Additional Securities, if any) issued under the Indenture remains outstanding immediately after any such redemption (other than Securities held, directly or indirectly, by the Company or its Affiliates); and

(2) the Company makes such redemption not more than 90 days after the consummation of any such Public Equity Offering.

Prior to August 1, 2016, the Company shall be entitled at its option to redeem some or all of the Securities at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and accrued and unpaid interest to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date).

6. Notice of Redemption

Notice of redemption shall be mailed by first-class mail at least 30 but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at his registered address, except that redemption notices may be mailed more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Securities or a satisfaction and discharge of the Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Security redeemed in accordance with provisions of the Indenture. No Securities of a principal amount of $2,000 or less shall be redeemed in part. On and after the redemption date, interest will cease to accrue on Securities or portions thereof called for redemption as long as the Company has deposited with the Paying Agent funds in satisfaction of the applicable redemption price.

7. Put Provisions

Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Company purchase all or a portion of such Holder’s Securities at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture.

8. Guarantee

The payment by the Company of the principal of, and premium and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior basis by each of the Guarantors to the extent set forth in the Indenture.

9. Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of $2,000 and any greater integral multiple of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date.

10. Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of it for all purposes.

11. Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

12. Discharge and Defeasance

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

13. Amendment; Waiver

Subject to certain exceptions set forth in the Indenture, (a) the Indenture may be amended with the consent of the Holders of a majority in principal amount of the then outstanding Securities and (b) Holders of a majority in principal amount of the outstanding Securities 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 any Securities. Subject to certain exceptions set forth in the Indenture, without the consent of the Holders, the Company, the Guarantors and the Trustee shall be entitled to amend the Indenture to cure ambiguities, omissions, defects or inconsistencies, or to provide for the assumption by a successor corporation of the obligations of the Company or any Guarantor under the Indenture, or to provide for uncertificated Securities in addition to or in place of certificated Securities, or to add guarantees with respect to the Securities, including any Guarantee, or to add to the covenants or surrender rights and powers conferred upon the Company or any Guarantor, or to make any change that does not adversely affect the rights of any Holder, or to comply with any requirement of the Commission in connection with the qualification of the Indenture under the Act, or to conform the text of the Indenture, the Securities or any Guarantee to any provision of the “Description of Notes”, to make amendments to the provisions of the Indenture relating to the transfer and legending of the Securities, or to release Collateral from the Lien under the Security Documents or a Guarantor from its Guarantee, in each case pursuant to and in accordance with the Indenture, the Security Documents and the Intercreditor Agreement when permitted or required by such documents.

14. Defaults and Remedies

Under the Indenture, Events of Default include (a) the failure to pay interest on any Security when the same becomes due and payable and the default continues for a period of 30 days; (b) the failure to pay the principal on any Security, when such principal becomes due and payable, at maturity, upon redemption, upon declaration of acceleration or otherwise (including the failure to make a payment to purchase Securities tendered pursuant to a Change of Control Offer or a Net Proceeds Offer); (c) failure by the Company to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (d) certain accelerations (including failure to pay within any applicable grace periods after final maturity) of other Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds $25,000,000; (e) certain events of bankruptcy or insolvency with respect to the Company, any Guarantor or any Significant Subsidiary; (f) certain judgments or decrees for the payment of money in excess of $25,000,000; (g) certain defaults with respect to Guarantees; and (h) certain defaults with respect to Collateral and the Security Documents. If an Event of Default shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities may declare the principal of and accrued interest on all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being due and payable immediately upon the occurrence of such Events of Default.

Subject to the provisions of the Indenture relating to the duties of the Trustee or the Notes Collateral Agent, neither the Trustee nor the Notes Collateral Agent is under any obligation to exercise any of its rights or powers under the Indenture, the Securities, the Guarantees or the Security Documents at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee or the Notes Collateral Agent, as applicable, 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 Securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee and the Notes Collateral Agent or exercising any trust or power conferred on the Trustee or the Notes Collateral Agent, as applicable. Holders of the Securities may not enforce the Indenture or the Securities except as provided in the Indenture and under the Act. Notwithstanding the foregoing in no event may any Holder enforce any Lien of the Notes Collateral Agent pursuant to the Security Documents. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if a committee of its Trust Officers in good faith determines that withholding notice is not opposed to the interests of the Holders.

15. Trustee Dealings with the Company

Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

16. No Recourse Against Others

No director, officer, employee, incorporator or stockholder of the Company or any Guarantor shall have any liability for any obligations of the Company or any Guarantor under the Securities, any Guarantee or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.

17. Authentication

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

18. Abbreviations

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

19. CUSIP Numbers

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Securityholders.

21. Governing Law.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

22. Security

The Securities and the Guarantees shall be secured by the Collateral on the terms and subject to the conditions set forth in the Indenture and the Security Documents. The Trustee and the Notes Collateral Agent, as the case may be, hold the Collateral in trust for the benefit of the Trustee and the Holders, in each case pursuant to the Security Documents and the Intercreditor Agreement. Each Holder, by accepting this Security, consents and agrees to the terms of the Security Documents and the Intercreditor Agreement as the same may be in effect or may be amended from time to time in accordance with their terms and the Indenture and authorizes and directs the Notes Collateral Agent to enter into the Security Documents and the Intercreditor Agreement, and to perform its obligations and exercise its rights thereunder in accordance therewith
