For purposes of determining the ABL Cap Amount (as defined in the Intercreditor Agreement), the Borrowing Base will be calculated by the Company

5 as of the last day of the most recent fiscal quarter of the Company for which financial statements are available and such calculations, as set forth in an Officers’ Certificate, will be deemed to be conclusive absent manifest error. “Business Day” means each day which is not a Legal Holiday. “Capital Lease Obligation” means an obligation that is required to be classified and accounted for as a capital lease for financial reporting purposes in accordance with GAAP, and the amount of Indebtedness represented by such obligation shall be the capitalized amount of such obligation determined in accordance with GAAP; and the Stated Maturity thereof shall be the date of the last payment of rent or any other amount due under such lease prior to the first date upon which such lease may be terminated by the lessee without payment of a penalty.

7 under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated and not replaced) on the date of the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, then EBITDA and Consolidated Interest Expense for such period shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary had not earned the interest income actually earned during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness; (3) if, since the beginning of such period, the Company or any Restricted Subsidiary shall have made any Asset Disposition, then EBITDA for such period shall be reduced by an amount equal to the EBITDA (if positive) directly attributable to the assets that were the subject of such Asset Disposition for such period, or increased by an amount equal to the EBITDA (if negative) directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale); (4) if, since the beginning of such period, the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction requiring a calculation to be made hereunder, which constitutes all or substantially all of an operating unit of a business, then EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition had occurred on the first day of such period; and (5) if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) above if made by the Company or a Restricted Subsidiary during such period, then EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition had occurred on the first day of such period.

8 For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of the Company. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate. If any Indebtedness is incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness shall be calculated based on the average daily balance of such Indebtedness for the four fiscal quarters subject to the pro forma calculation to the extent that such Indebtedness was incurred solely for working capital purposes. “Consolidated Current Liabilities” as of the date of determination means the aggregate amount of liabilities of the Company and its consolidated Restricted Subsidiaries which may properly be classified as current liabilities (including taxes accrued as estimated), on a consolidated basis, after eliminating: (1) all intercompany items between the Company and any Restricted Subsidiary; (2) all current maturities of long-term Indebtedness, all as determined in accordance with GAAP consistently applied; and (3) any liabilities resulting from xxxx to market requirement of any derivative security. “Consolidated Interest Expense” means, for any period, the total interest expense (less interest income) of the Company and its consolidated Restricted Subsidiaries (other than non-cash interest expense attributable to convertible indebtedness under Accounting Practices Bulletin 14-1 or any successor provision), plus, to the extent not included in such total interest expense, and to the extent incurred by the Company or its Restricted Subsidiaries, without duplication: (1) interest expense attributable to Capital Lease Obligations, the interest portion of rent expense associated with Attributable Indebtedness in respect of the relevant lease giving rise thereto, determined as if such lease were a capitalized lease in accordance with GAAP, and the interest component of any deferred payment obligations; (2) amortization of debt discount (including the amortization of original issue discount resulting from the issuance of Indebtedness at less than par) and debt issuance cost; provided, however, that any amortization of bond

9 premium will be credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such amortization of bond premium has otherwise reduced Consolidated Interest Expense; (3) capitalized interest; (4) non-cash interest expense; provided, however, that any non-cash interest expense or income attributable to the movement in the xxxx to market valuation of Hedging Obligations or other derivative instruments pursuant to GAAP shall be excluded from the calculation of Consolidated Interest Expense); (5) commissions, discounts and other fees and charges owed with respect to letters of credit and bankers’ acceptance financing; (6) net payments pursuant to Hedging Obligations; (7) the product of (a) all dividends accrued in respect of all Disqualified Stock of the Company and all Preferred Stock of any Restricted Subsidiary, in each case, held by Persons other than the Company or a Restricted Subsidiary (other than dividends payable solely in Capital Stock (other than Disqualified Stock) of the Company), times (b) a fraction of the numerator of which is one and the denominator of which is one minus the effective combined tax rate of the issuer of such Disqualified Stock or Preferred Stock (expressed as a decimal) for such period (as estimated by the chief financial officer of the Company in good faith); (8) interest incurred in connection with Investments in discontinued operations; (9) interest accruing on any Indebtedness of any other Person to the extent such Indebtedness is Guaranteed by (or secured by a Lien on the assets of) the Company or any Restricted Subsidiary; and (10) the cash contributions to any employee stock ownership plan or similar trust to the extent such contributions are used by such plan or trust to pay interest or fees to any Person (other than the Company) in connection with Indebtedness Incurred by such plan or trust. “Consolidated Leverage Ratio” as of any date of determination means the ratio of (x) the aggregate amount of Indebtedness of the Company and its Restricted Subsidiaries as of such date of determination to (y) the aggregate amount of EBITDA for the period of the most recent four consecutive fiscal quarters for which financial statements of the Company are available; provided, however, that: (1) if the Company or any Restricted Subsidiary has Incurred any Indebtedness since the beginning of such period that remains outstanding or if the transaction giving rise to the need to calculate the Consolidated Leverage Ratio is an Incurrence of Indebtedness, or both, then EBITDA and the amount of such

10 Indebtedness for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period; (2) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged (in each case other than Indebtedness Incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and the related commitment terminated and not replaced) on the date of the transaction giving rise to the need to calculate the Consolidated Leverage Ratio, then EBITDA and the aggregate amount of Indebtedness shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary had not earned the interest income actually earned during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness; (3) if, since the beginning of such period, the Company or any Restricted Subsidiary shall have made any Asset Disposition, then EBITDA for such period shall be reduced by an amount equal to the EBITDA (if positive) directly attributable to the assets that were the subject of such Asset Disposition for such period, or increased by an amount equal to the EBITDA (if negative) directly attributable thereto for such period; (4) if, since the beginning of such period, the Company or any Restricted Subsidiary (by merger or otherwise) shall have made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction requiring a calculation to be made hereunder, which constitutes all or substantially all of an operating unit of a business, then EBITDA for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition had occurred on the first day of such period; and (5) if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (3) or (4) above if made by the Company or a Restricted Subsidiary during such period, then EBITDA for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition had occurred on the first day of such period. For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings relating thereto and the

11 amount of Consolidated Interest Expense associated with any Indebtedness Incurred in connection therewith, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of the Company. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate. If any Indebtedness is incurred under a revolving credit facility and is being given pro forma effect, the interest on such Indebtedness shall be calculated based on the average daily balance of such Indebtedness for the four fiscal quarters subject to the pro forma calculation to the extent that such Indebtedness was incurred solely for working capital purposes. “Consolidated Net Income” means, for any period, the net income of the Company and its consolidated Subsidiaries; provided, however, that there shall not be included in such Consolidated Net Income: (1) any net income of any Person (other than the Company) if such Person is not a Restricted Subsidiary, except that: (A) subject to the exclusion contained in clause (4) below, the Company’s equity in the net income of any such Person for such period shall be included in such Consolidated Net Income up to the aggregate amount of cash actually distributed by such Person during such period to the Company or a Restricted Subsidiary as a dividend or other distribution (subject, in the case of a dividend or other distribution paid to a Restricted Subsidiary, to the limitations contained in clause (3) below); and (B) the Company’s equity in a net loss of any such Person for such period shall be included in determining such Consolidated Net Income; (2) any net income (or loss) of any Person acquired by the Company or a Subsidiary in a pooling of interests transaction (or any transaction accounted for in a manner similar to a pooling of interests) for any period prior to the date of such acquisition;

Article 2 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. 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.

44 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 $200,000,000 of 8.500% Senior Secured Notes Due 2018 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. 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

45 agree in writing that the Paying Agent shall hold in trust for the benefit of Holders 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. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. 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 Holders. 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(a) 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. To permit registration of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s or co-registrar’s request. The Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.06, 4.06, 4.09 and 9.05). The Company shall not be required to make and the Registrar need not register transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof 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. Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co- registrar shall be affected by notice to the contrary. All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange.

46 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. 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, but in certain circumstances, Section 12.06 provides that certain Securities shall be disregarded for certain purposes. 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

47 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 Holders 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 Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid. 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. All the Securities issued under this Indenture shall be treated as a single class for all purposes of this Indenture including waivers, amendments, redemptions and offers to purchase. With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, and, if the Company so elects, a supplemental indenture, a copy of each of 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; provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to not be fungible for U.S. federal income tax purposes with any other Securities issued under this Indenture; and

48 (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 Section 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. SECTION 3.02. Selection of Securities to Be Redeemed. If fewer than all the Securities are to be redeemed, the Trustee shall select Securities (a) if the Securities are listed on any national securities exchange, in compliance with the requirements of such exchange, (b) if the Securities are held by The Depository Trust Company and The Depository Trust Company prescribes a method of selection, in accordance with such procedures and (c) on a pro rata basis to the extent practicable. 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 send a notice of redemption to each Holder of Securities to be redeemed at such Holder’s registered address, except that redemption notices may be sent 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;

49 (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, or a condition precedent to such redemption is not satisfied, 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; (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; and (8) if the notice of redemption is subject to one or more conditions precedent as provided in Section 3.04, a statement to that effect and a description of such condition or conditions. 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 sent, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice; provided that any notice of redemption sent in connection with a Qualified Equity Offering, other securities offering or any other financing, or a transaction (or a series of related transactions) that constitutes a Change of Control, may be given, at the Company’s discretion, prior to the consummation thereof and be subject to one or more conditions precedent, including consummation of the related Qualified Equity Offering, securities offering or other financing or Change of Control, as applicable, in which case the Company may revoke such notice on or prior to the specified redemption date if any such condition is not or will not be satisfied. Unless the Company defaults in making such redemption payment or a condition precedent to such redemption is not satisfied, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date. 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.

50 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.

63 Company or such Restricted Subsidiary shall so reduce any Other Pari Passu Lien Obligations, the Company will equally and ratably reduce Indebtedness under the Securities by making an offer to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, the pro rata principal amount of the Securities, such offer to be conducted in accordance with the procedures set forth below for an Asset Disposition Offer but without any further limitation in amount; or (B) to the extent such Net Available Cash is from Asset Dispositions of Collateral deemed to be an Excluded Asset, to reduce Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor; provided, however, that in connection with any prepayment, repayment or purchase of Indebtedness pursuant to this clause (B), such Restricted Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, purchased or otherwise retired, (C) to the extent the Company elects, to acquire Additional Assets within 365 days of the receipt of such Net Available Cash; provided that, without limitation of the provisions of Section 4.15, any such Additional Assets, including the assets of any Person that becomes a Subsidiary Guarantor as a result of such transactions acquired with Net Available Cash from an Asset Disposition of Notes Priority Collateral are concurrently with their acquisition added to the Notes Priority Collateral; provided further that, in the case of this clause (C), a binding commitment shall be treated as a permitted application of the Net Available Cash from the date of such commitment so long as the Company or such Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Available Cash will be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable Commitment”) and if any Acceptable Commitment is later cancelled or terminated for any reason before such Net Available Cash is applied, then such Net Available Cash shall constitute Excess Proceeds; or (D) a combination of the foregoing, in each case of (A) and (B), other than Indebtedness owed to the Company or an Affiliate of the Company; and (6) Any Net Available Cash from the Asset Dispositions covered by this Section 4.06(a) that is not invested or applied, or committed to be invested or applied, as provided in Section 4.06(a)(5) will be deemed to constitute “Excess Proceeds”. When the aggregate amount of Excess Proceeds exceeds $15,000,000, within 30 days thereof, the Company shall make an Asset Disposition Offer to all Holders, and, if required by the terms of any Other Pari Passu Lien Obligations, to

64 the holders of such Other Pari Passu Lien Obligations, to purchase the maximum aggregate principal amount of the Securities and any such Other Pari Passu Lien Obligations that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount of the Securities and Other Pari Passu Lien Obligations, in each case, plus accrued and unpaid interest, if any, to, but not including, the date of purchase, subject to, without duplication, the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, in accordance with the procedures set forth in this Indenture or the agreements governing the Other Pari Passu Lien Obligations, as applicable, and, with respect to the Securities, in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof. The Company will commence an Asset Disposition Offer with respect to Excess Proceeds within 30 days after the date that Excess Proceeds exceed $15,000,000 by providing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Company may satisfy the foregoing obligation with respect to such Net Available Cash from an Asset Disposition by making an Asset Disposition Offer with respect to such Net Available Cash prior to the expiration of the Application Period. To the extent that the aggregate amount of Securities and such Other Pari Passu Lien Obligations so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities or Other Pari Passu Lien Obligations surrendered in any Asset Disposition Offer by Holders and holders or lenders of Other Pari Passu Lien Obligations exceeds the amount of Excess Proceeds, the Company shall select the Securities and such Other Pari Passu Lien Obligations to be purchased on a pro rata basis based on the principal amounts tendered or required to be prepaid or redeemed; provided that no Securities or Other Pari Passu Lien Obligations shall be selected and purchased in an unauthorized denomination. Upon completion of any Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero. After the Company or any Restricted Subsidiary has applied the Net Available Cash from any Asset Disposition covered by this clause (a) as provided in, and within the time periods required by, this clause (a), the balance of such Net Available Cash, if any, from such Asset Disposition shall be released by the Noteholder Collateral Agent to the Company or such Restricted Subsidiary for use by Company or such Restricted Subsidiary for any purpose not prohibited by the terms of this Indenture. (b) The Company shall not, and shall not permit any Restricted Subsidiary to, make any Asset Disposition of any ABL Priority Collateral, unless: (1) the Company or such Restricted Subsidiary receives consideration at the time of such Asset Disposition at least equal to the Fair Market Value (including as to the value of all non-cash consideration) of the shares and other assets subject to such Asset Disposition;

65 (2) at least 75% of the consideration thereof received by the Company or such Restricted Subsidiary is in the form of cash or Temporary Cash Investments; and (3) an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied by the Company (or such Restricted Subsidiary, as the case may be) within 365 days of the receipt of such Net Available Cash (A) to permanently reduce any Indebtedness under the Credit Agreement or any other Indebtedness of the Company or a Subsidiary Guarantor that, in each case, is secured by a Lien on the ABL Priority Collateral that is prior to the Lien on the ABL Priority Collateral in favor of Holders (and, in the case of revolving obligations, to correspondingly reduce commitments with respect thereto), in each case other than Indebtedness owed to the Company or a Subsidiary of the Company, (B) to acquire Additional Assets in a manner and within the time limitation set forth in clause (a)(5)(C) above; or (C) a combination of the foregoing; provided that, in the case of clause (b)(3)(B) above, an Acceptable Commitment shall be treated as a permitted application of the Net Available Cash from the date of such commitment; provided further that if any Acceptable Commitment is later cancelled or terminated for any reason before such Net Available Cash is applied, then such Net Available Cash shall constitute Excess ABL Proceeds (as defined below). (4) Any Net Available Cash from an Asset Disposition covered by this Section 4.06(b) that is not invested or applied, or committed to be invested or applied, as provided in Section 4.06(b)(3) will be deemed to constitute “Excess ABL Proceeds”. When the aggregate amount of Excess ABL Proceeds exceeds $15,000,000, within 30 days thereof, the Company shall make an offer (an “ABL Asset Disposition Offer”) to all Holders, and, if required by the terms of any Other Pari Passu Lien Obligations to the holders of such Other Pari Passu Lien Obligations, to purchase the maximum aggregate principal amount of the Securities and any such Other Pari Passu Lien Obligations, that may be purchased out of the Excess ABL Proceeds at an offer price in cash in an amount equal to 100% of the principal amount of the Securities and Other Pari Passu Lien Obligations, in each case, plus accrued and unpaid interest, if any, to, but not including, the date of purchase, subject to, without duplication, the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, in accordance with the procedures set forth in this Indenture or the agreements governing the Other Pari Passu Lien Obligations, as applicable, and, with respect to the Securities, in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof. The Company shall commence an ABL Asset Disposition Offer with respect to Excess ABL Proceeds

66 within 30 days after the date that Excess ABL Proceeds exceed $15,000,000 by providing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Company may satisfy the foregoing obligation with respect to such Net Available Cash from an Asset Disposition by making an ABL Asset Disposition Offer with respect to such Net Available Cash prior to the expiration of the Application Period. To the extent that the aggregate amount of the Securities and such Other Pari Passu Lien Obligations so validly tendered and not properly withdrawn pursuant to an ABL Asset Disposition Offer is less than the Excess ABL Proceeds, the Company may use any remaining Excess ABL Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of the Securities or Other Pari Passu Lien Obligations surrendered in any ABL Asset Disposition Offer by the Holders and holders or lenders of Other Pari Passu Lien Obligations exceeds the amount of Excess ABL Proceeds, the Company shall select the Securities and such Other Pari Passu Lien Obligations to be purchased on a pro rata basis based on the principal amounts tendered or required to be prepaid or redeemed; provided that no Securities or Other Pari Passu Lien Obligations will be selected and purchased in an unauthorized denomination. Upon completion of any such ABL Asset Disposition Offer, the amount of Excess ABL Proceeds shall be reset at zero. (c) For the purposes of this Section 4.06, any sale by the Company or a Restricted Subsidiary of the Capital Stock of a Restricted Subsidiary that owns assets constituting Non-ABL Priority Collateral or ABL Priority Collateral shall be deemed to be a sale of such Non-ABL Priority Collateral or ABL Priority Collateral (or, in the event of a Restricted Subsidiary that owns assets that include any combination of Non-ABL Priority Collateral and ABL Priority Collateral, a separate sale of each of such Non-ABL Priority Collateral and ABL Priority Collateral). 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 pursuant to Section 4.1 of the Intercreditor Agreement. (d) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.06. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.06, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.06 by virtue of its compliance with such securities laws or regulations. (e) In the event of the transfer of substantially all (but not all) of the assets of the Company and the Restricted Subsidiaries as an entirety to a Person in accordance with this Indenture, the successor shall be deemed to have sold for cash at Fair Market Value the assets of the Company and the Restricted Subsidiaries not so transferred for purposes of this Section 4.06, and shall comply with the provisions of this

67 Section 4.06 with respect to such deemed sale as if it were an Asset Disposition (with such Fair Market Value being deemed to be Net Available Cash for such purpose). (f) Pending application of Net Available Cash pursuant to this Section 4.06, such Net Available Cash may be invested in Temporary Cash Investments or applied to temporarily reduce revolving credit indebtedness. For the purposes of Section 4.06(a)(2) and (b)(2), the following are deemed to be Temporary Cash Investments: (1) the assumption or discharge of senior secured Indebtedness of the Company or any Subsidiary Guarantor (other than obligations in respect of Disqualified Stock of the Company or Preferred Stock of a Subsidiary Guarantor) or any Indebtedness or Preferred Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition; (2) any securities or other obligations received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash within 90 days after such Asset Disposition, to the extent of the cash received in that conversion; and (3) the Fair Market Value of (i) any assets (other than securities) received by the Company or any Restricted Subsidiary to be used by it in the Related Business, (ii) Capital Stock in a Person that is a Restricted Subsidiary or in a Person engaged in the Related Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Company or any Restricted Subsidiary or (iii) a combination of (i) and (ii). (g) All references herein to “Net Available Cash”, “Excess Proceeds” and “Excess ABL Proceeds” shall be deemed to mean cash in an amount equal to the amount of Net Available Cash, Excess Proceeds or Excess ABL Proceeds, as applicable, but, except in the case of any Net Available Cash from any Asset Disposition of Notes Priority Collateral (which shall be paid or deposited pursuant to clause (a)(4) above), not necessarily the actual cash received from the relevant Asset Disposition. The Company and its Subsidiaries shall have no obligation to segregate, trace or otherwise identify Net Available Cash, Excess Proceeds or ABL Excess Proceeds (other than the amount thereof and pursuant to clause (a)(4) above), it being agreed that cash is fungible and that the Company’s obligations under this Section 4.06 may be satisfied by the application of funds from other sources. SECTION 4.07. Limitation on Affiliate Transactions. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or permit to exist any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with (which term, for purposes of this Section 4.07, shall include “for the benefit of” where appropriate in the context) any Affiliate of the Company (an “Affiliate Transaction”) unless: (1) the terms of the Affiliate Transaction are not materially less favorable to the Company or such Restricted Subsidiary than those that could reasonably be expected to be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate;

68 (2) if such Affiliate Transaction involves an amount in excess of $10,000,000, the terms of the Affiliate Transaction are set forth in writing and a majority of the non-employee directors of the Company disinterested with respect to such Affiliate Transaction have determined in good faith that the criteria set forth in clause (1) are satisfied and have approved the relevant Affiliate Transaction as evidenced by a resolution of the Board of Directors; and (3) if such Affiliate Transaction involves an amount in excess of $20,000,000, the Board of Directors shall also have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and its Restricted Subsidiaries or is not materially less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate. (b) The provisions of Section 4.07(a) shall not prohibit: (1) (i) any Restricted Payment permitted to be made pursuant to Section 4.04 or any Permitted Investment and (ii) any Permitted Lien; (2) any employment agreement or other employment compensation plan in existence on the Issue Date or entered into thereafter in the ordinary course of business, including any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock options and stock ownership plans approved by the Board of Directors; (3) reasonable compensation (including bonuses) and other benefits (including retirement, health, stock option and other benefit plans), indemnification arrangements, employment and severance agreements provided on behalf of directors, officers and employees of the Company or its Restricted Subsidiaries, in each case, approved by the Board of Directors or, in the case of indemnification arrangements, consistent with applicable charter, by-law or statutory provisions; (4) any transaction with the Company, a Restricted Subsidiary or joint venture or similar entity that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or similar entity; (5) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company; (6) transactions with customers, clients, vendors, suppliers or other purchasers or sellers of goods or services, in each case in the ordinary course of business (including pursuant to joint venture agreements);

69 (7) any transaction on arm’s length terms with any non-Affiliate that becomes an Affiliate as a result of such transaction; (8) any agreement as in effect on the Issue Date and described in the Offering Memorandum or any renewals or extensions of any such agreement (so long as such renewals or extensions, taken as a whole, are not materially less favorable to the Company or the Restricted Subsidiaries) and the transactions evidenced thereby; and (9) reasonable advances to or reimbursements of employees for moving expenses, travel expenses and similar expenditures, in each case, in the ordinary course of business of the Company or any of its Restricted Subsidiaries. SECTION 4.08. Limitation on Line of Business. The Company shall not, and shall not permit any Restricted Subsidiary, to engage in any business other than a Related Business, except to such extent as would not be material to the Company and its Restricted Subsidiaries as a whole. SECTION 4.09. Change of Control. (a) Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Company repurchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof on the date of repurchase 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), in accordance with the terms contemplated in Section 4.09(b). (a) Within 30 days following any Change of Control unless the Company has previously or concurrently mailed a redemption notice with respect to all outstanding Securities as described under Section 3.03, the Company shall send a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating: (1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase, 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 on the relevant interest payment date); (2) the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control); (3) the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is sent);

70 (4) if such notice is delivered prior to the occurrence of a Change of Control, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control, and, if applicable, stating that, in the Company’s discretion, the purchase date may be delayed until such time as any or all such conditions shall be satisfied, or that such purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the purchase date, or by the purchase date as so delayed; and (5) the instructions, as determined by the Company, consistent with this Section, that a Holder must follow in order to have its Securities purchased. (b) Holders electing to have a Security purchased will be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders will be entitled to withdraw their election if the Trustee or the Company receives, not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such Security purchased. (c) On the purchase date, all Securities purchased by the Company under this Section shall be delivered by the Company to the Trustee for cancellation, and the Company shall pay the purchase price plus accrued and unpaid interest, if any, to the Holders entitled thereto. (d) In the event a Change of Control occurs at a time when the Company is prohibited by the terms of the Credit Agreement from making a Change of Control Offer or from purchasing the Securities pursuant thereto, prior to providing the notice to Holders described in Section 4.09(b), but in any event within 30 days following any Change of Control, the Company shall: (1) repay in full all Indebtedness outstanding under the Credit Agreement and terminate all commitments thereunder or offer to repay in full all such Indebtedness and repay the indebtedness of each lender who has accepted such offer (and terminate such lender’s commitment); or (2) obtain the requisite consent under the Credit Agreement to permit the purchase of the Securities as described above. The Company must first comply with the first sentence of this Section 4.09(e) before it shall be required to purchase Securities in the event of a Change of Control; provided, however, that the Company’s failure to comply with the first sentence of this Section 4.09(e) or to make a Change of Control Offer because of any such failure shall constitute a default described in Section 6.01(4) (and not under Section 6.01(2)). (e) The Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in

71 this Indenture applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer. A Change of Control Offer may be made in advance of a Change of Control, and may be conditional upon such Change of Control if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer. (f) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section, the Company shall comply with the applicable securities laws and regulations and shall be deemed not to have breached its obligations under this Section by virtue of its compliance with such securities laws or regulations. SECTION 4.10. Limitation on Liens. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, Incur or permit to exist any Lien (the “Initial Lien”) of any nature whatsoever on any of its properties (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, securing any Indebtedness, other than: (1) in the case of the Notes Priority Collateral, any Initial Lien if (i) such Initial Lien expressly ranks junior to the first-priority Lien intended to be created in favor of the Noteholder Collateral Agent for the benefit of the Trustee, the Noteholder Collateral Agent and the Holders, 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 (ii) such Initial Lien is a Permitted Collateral Lien; (2) in the case of the ABL Priority Collateral, any Initial Lien if (i) the Securities and the Subsidiary 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 (ii) such Initial Lien is a Permitted Lien; and (3) in the case of any other asset or property, any Initial Lien if (i) the Securities and the Subsidiary Guarantees are equally and ratably secured with (or on a senior basis to, in the case such Initial Lien secures any Subordinated Obligation) the obligations secured by such Initial Lien or (ii) such Initial Lien is a Permitted Lien. (b) Any such Lien thereby created securing the Securities or any Subsidiary Guarantee pursuant to clause (a)(2) or (3) of this Section shall be automatically and unconditionally released and discharged upon (i) the release and discharge of each Initial Lien to which it relates, (ii) in the case of such Lien securing any such Subsidiary Guarantee, upon the termination and discharge of such Subsidiary Guarantee in accordance with the terms of this Indenture or (iii) any sale, exchange or transfer to any Person not an Affiliate of the Company of the property or assets secured by such Initial Lien, in each case, which release and discharge in the case of any sale of

72 any asset or property shall not affect any Lien that the Noteholder 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 Noteholder Collateral Agent in respect of the Notes Priority Collateral or the ABL Priority Collateral. SECTION 4.11. Limitation on Sale/Leaseback Transactions. The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with respect to any property unless (a) the Company or such Restricted Subsidiary would be entitled to (1) Incur Indebtedness in an amount equal to the Attributable Debt with respect to such Sale/Leaseback Transaction pursuant to Section 4.03 and (2) (i) in the case of a Sale/Leaseback Transaction involving Notes Priority Collateral, create a Permitted Collateral Lien on such Notes Priority Collateral securing such Attributable Debt or (ii) in the case of a Sale/Leaseback Transaction involving ABL Priority Collateral or any other property or asset, create a Permitted Lien on such ABL Priority Collateral, property or asset, as applicable, securing such Attributable Debt, (b) the net proceeds received by the Company or any Restricted Subsidiary in connection with such Sale/Leaseback Transaction are at least equal to the Fair Market Value of such property and (c) the Company applies the proceeds of such transaction in compliance with Section 4.06. SECTION 4.12. Future Subsidiary Guarantors. The Company shall cause each Restricted Subsidiary that enters into a Guarantee of any Indebtedness of the Company or any Restricted Subsidiary (other than a Foreign Subsidiary that Guarantees only Indebtedness Incurred by another Foreign Subsidiary) to execute and deliver to the Trustee a Guarantee Agreement pursuant to which such Restricted Subsidiary will Guarantee payment of the Securities on a senior secured basis on the same terms and conditions as those set forth in Article 10 of this Indenture and applicable to the other Subsidiary Guarantors and joinders or supplements, as applicable, in form and substance reasonably satisfactory to the Trustee, to the Security Documents and the 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. SECTION 4.13. Impairment of Security Interest. The Company shall not, and shall not permit any of its Restricted Subsidiaries to, take or knowingly or negligently omit to take, any action which action or omission might or would have the result of materially impairing the security interest with respect to the Collateral for the benefit of the Noteholder Secured Parties. SECTION 4.14. Information Regarding Collateral. The Company shall furnish to the Noteholder Collateral Agent, with respect to the Company or any Subsidiary Guarantor, written notice within 10 Business Days of any change in such

73 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 Subsidiary Guarantors shall make all filings under the Uniform Commercial Code or equivalent statutes or otherwise that are required by applicable law in order for the Noteholder Collateral Agent to continue at all times following such change to have a valid, legal and perfected security interest in all the Collateral. SECTION 4.15. 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 Subsidiary 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 Noteholder Collateral Agent may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the Lien 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, after the Issue Date, the Company or a Subsidiary 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 Subsidiary 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 Subsidiary Guarantor, then the Company or such Subsidiary Guarantor shall, within 90 days after such 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 Noteholder Collateral Agent may agree in its sole discretion) and as soon as practicable (with respect to other assets), provide a Lien over such property (or, in the case of a new Subsidiary Guarantor, its assets that would constitute Collateral under the Security Documents) in favor of the Noteholder Collateral Agent and deliver certain joinder agreements or supplements as required by the Security Documents. Notwithstanding the foregoing, until the Discharge of ABL Obligations, the Company and the Subsidiary 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. (b) In addition, the Company and the Subsidiary Guarantors shall: (1) on or before the date that is 120 days after the Issue Date, deliver to the Noteholder Collateral Agent (A) a policy or policies of title insurance 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, (B) 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 (C) such surveys,

74 abstracts, appraisals, legal opinions and other documents as the Noteholder Collateral Agent may reasonably request with respect to any such mortgage or mortgaged property; (2) on or before the date that is 120 days after the Issue Date, deliver to the Noteholder Collateral Agent such filings, registrations or recordations, executed and in proper form for filing, registration or recordation, required pursuant to the Security Documents in respect of the Specified Trucks; and (3) on or before the date that is 120 days after the Issue Date, deliver to the Noteholder Collateral Agent evidence satisfactory to it that the Company and the Subsidiary Guarantors maintain insurance with respect to the Collateral as required pursuant to the Security Documents. SECTION 4.16. 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 4.17. Further Instruments and Acts. Upon request of the Trustee, the Company will 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. Article 5 Successor Company SECTION 5.01. When Company May Merge or Transfer Assets. (a) The Company shall not consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, directly or indirectly, all or substantially all its assets to, any Person, unless: (1) the Company shall be the surviving corporation or the resulting, surviving or transferee Person (the “Successor Company”) shall be a corporation, limited liability company or limited partnership organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company) shall expressly assume, by an indenture supplemental thereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Securities, this Indenture and the Security Documents; provided that if such Person is a limited liability company or a limited partnership, such Person

75 will form a Wholly Owned Subsidiary that is a corporation and cause such Wholly Owned Subsidiary to become a co-issuer of the Securities; (2) immediately after giving pro forma effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Company or any Subsidiary as a result of such transaction as having been Incurred by such Successor Company or such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; (3) immediately after giving pro forma effect to such transaction, either (A) the Successor Company would be able to Incur an additional $1.00 of Coverage Indebtedness pursuant to Section 4.03(a) or (B) the Consolidated Coverage Ratio of the Successor Company is greater than the Consolidated Coverage Ratio of the Company immediately prior to giving effect to such transaction; (4) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture or applicable Security Documents comply with this Indenture; (5) to the extent any assets of the Person which is consolidated with or merged with or into the Successor Company are assets of the type which would constitute Collateral under the Security Documents, the Successor Company will 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 Successor Company shall: (a) continue to constitute Collateral under this Indenture and the Security Documents, (b) be subject to the Lien in favor of the Noteholder Collateral Agent for the benefit of the Trustee and the Holders 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; provided, however, that clause (3) will not be applicable to (A) a Restricted Subsidiary consolidating with, merging into or transferring all or part of its properties and assets to the Company (so long as no Capital Stock of the Company is distributed to any Person) or (B) the Company merging with an Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction. For purposes of this Section 5.01, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and

76 assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. The Successor Company shall be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, the Subsidiary Guarantees and the Security Documents and the predecessor Company, except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Securities. For all purposes of this Indenture, Subsidiaries of any Successor Company shall, upon any transaction subject to this Section 5.01, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture, and all Indebtedness and Liens of the Successor Company and its Subsidiaries that was not Indebtedness or Liens on property or assets, as the case may be, of the Company and its Subsidiaries immediately prior to such transaction shall be deemed to have been Incurred upon such transaction. (b) The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to any Person unless: (1) except in the case of a Subsidiary Guarantor (x) that has been, or will be as a result of a transaction, disposed of in its entirety to another Person (other than to the Company or an Affiliate of the Company), whether through a merger, consolidation or sale of Capital Stock or assets or (y) that, as a result of the disposition of all or a portion of its Capital Stock, ceases to be a Subsidiary, in each case, if in connection therewith the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.06 in respect of such disposition, the resulting, surviving or transferee Person (if not such Subsidiary) shall be a Person organized and existing under the laws of the jurisdiction under which such Subsidiary was organized or under the laws of the United States of America, or any State thereof or the District of Columbia, and such Person shall expressly assume, by a Guarantee Agreement, in a form satisfactory to the Trustee, all the obligations of such Subsidiary, if any, under its Subsidiary Guarantee and the Security Documents; (2) immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any Indebtedness which becomes an obligation of the resulting, surviving or transferee Person as a result of such transaction as having been issued by such Person at the time of such transaction), no Default shall have occurred and be continuing; (3) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such Guarantee Agreement and the applicable Security Documents comply with this Indenture;

77 (4) to the extent any assets of the Person which is consolidated with or merged with or into the Successor Guarantor are assets of the type which would constitute Collateral under the Security Documents, the Successor Guarantor will 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 (5) the Collateral owned by or transferred to the Successor Guarantor shall (x) continue to constitute Collateral under this Indenture and the Security Documents, (y) be subject to the Lien favor of the Noteholder Collateral Agent for the benefit of the Trustee and the Holders and (z) not be subject to any Lien other than Permitted Liens and other Liens permitted under Section 4.10. Article 6 Defaults and Remedies SECTION 6.01. Events of Default. An “Event of Default” occurs if: (1) the Company defaults in the payment of interest on any Security when the same becomes due and payable, and such default continues for a period of 30 days; (2) the Company defaults in the payment of principal of any Security when the same becomes due and payable at its Stated Maturity, upon optional redemption, upon required purchase, upon declaration of acceleration or otherwise; (3) the Company fails to comply with Section 5.01; (4) the Company fails to comply (i) with Section 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 or 4.15 (other than a failure to purchase Securities when required under Section 4.06 or 4.09) and such failure continues for 30 days after the notice specified below or (ii) with Section 4.02 and such failure continues for 120 days after the notice specified below; (5) the Company or any Subsidiary Guarantor fails to comply with any of its other agreements contained in the Securities, this Indenture or in the Security Documents (other than those referred to in clause (1), (2), (3) or (4) above) and such failure continues for 60 days after the notice specified below; (6) Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary is not paid within any applicable grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $20,000,000, or its foreign currency equivalent at the time;

78 (7) the Company or any Significant Subsidiary 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; (8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company or any Significant Subsidiary in an involuntary case; (B) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or (C) orders the winding up or liquidation of the Company or any Significant Subsidiary; or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days; (9) any judgment or decree for the payment of money in excess of $20,000,000 (in excess of amounts covered by insurance policies issued by reputable and solvent insurance companies and as to which the relevant insurer has not disclaimed responsibility) or its foreign currency equivalent at the time is entered against the Company or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days following the entry of such judgment or decree and is not discharged, waived or the execution thereof stayed (the “judgment default provision”); (10) any Subsidiary Guarantee of any Significant Subsidiary ceases to be in full force and effect (other than in accordance with the terms of such Subsidiary Guarantee) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee; or (11) with respect to any Collateral, individually or in the aggregate, having a fair market value in excess of $5,000,000, (a) any of the Security Documents ceases to be in full force and effect, (b) any of the Security Documents ceases to give the Holders the Liens purported to be created thereby

79 with the priority contemplated thereby, or (c) any of the Security Documents is declared null and void or the Company or any Subsidiary Guarantor denies in writing that it has any further liability under any Security Document or gives written notice to such effect (in each case (i) other than in accordance with the terms of this Indenture, the Intercreditor Agreement and the Security Documents or (ii) unless waived by the requisite Holders if, after that waiver, the Company is in compliance with Section 4.15 and Article 11), except to the extent that any loss of perfection or priority results from the failure of the Noteholder Collateral Agent or the Bank Collateral Agent to maintain possession of certificates actually delivered to it representing securities pledged under the Security Documents, or otherwise results from the gross negligence, bad faith or willful misconduct of the Trustee, the Noteholder Collateral Agent or the Bank Collateral Agent (the “security default provision”). 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 “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. A Default under clauses (4) or (5) shall not be 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 to the Trustee, within 30 days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any Event of Default under clause (3), (6), (9), (10) or (11) and any event which with the giving of notice or the lapse of time would become an Event of Default under clause (4) or (5), its status and what action the Company is taking or proposes to take with respect thereto. Any default for the failure to deliver any report within the time periods prescribed in Section 4.02 or to deliver any notice or certificate pursuant to any other provision of this Indenture shall be deemed to be cured upon the subsequent delivery of any such report, notice or certificate, even though such delivery is not within the prescribed period specified. SECTION 6.02. Acceleration. (a) If an Event of Default (other than an Event of Default specified in clause (7) or (8) of Section 6.01 with respect to the Company) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and

80 interest shall be due and payable immediately. If an Event of Default specified in clause (7) or (8) of Section 6.01 with respect to the Company occurs and is continuing, the principal of and interest on all the 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 Holders. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may rescind any such acceleration with respect to the Securities and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto. (b) In the event of any Event of Default specified in clause (6) above, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of the acceleration of the Securities) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose, (x) the Indebtedness or Guarantee that is the basis for such Event of Default has been discharged, (y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured. 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. SECTION 6.04. Waiver of Past Defaults. Subject to Section 9.02(d), the Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on a Security, (b) a Default arising from the failure to redeem or purchase any Security when required pursuant to this Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. 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 Securities may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or the Noteholder Collateral Agent or of exercising any trust or power conferred on the Trustee or the

81 Noteholder Collateral Agent, as applicable. However, the Trustee and the Noteholder Collateral Agent may refuse to follow any direction that conflicts with law or this Indenture, the Securities, the Subsidiary Guarantees and the Security Documents or, subject to Section 7.01, that the Trustee and the Noteholder Collateral Agent determine is unduly prejudicial to the rights of other Holders or would involve the Trustee or the Noteholder Collateral Agent in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification reasonably 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) such Holder gives to the Trustee written notice stating that an Event of Default is continuing; (2) Holders of at least 25% in principal amount of the Securities make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer to the Trustee security or indemnity reasonably satisfactory to it 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. Notwithstanding the foregoing, in no event may any Holder enforce any Lien of the Noteholder Collateral Agent pursuant to the Security Documents. 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 or 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. 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

82 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. SECTION 6.10. Priorities. Subject to the terms of the Security Documents and the Intercreditor Agreement with respect to any proceeds of Collateral, if the Trustee or Noteholder Collateral Agent collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order: FIRST: to the Trustee for amounts due under Section 7.07 and to the Noteholder 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 THIRD: to the Company. 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 cause to be sent to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as 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

83 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 Securities. SECTION 6.12. 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) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs. (a) Except during the continuance of an Event of Default: (1) the Trustee undertakes to perform such duties and 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 (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, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (b) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct, except that: (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 negligent in ascertaining the pertinent facts; and

84 (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. (c) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. (d) 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. (e) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. (f) 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. (g) 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 conclusively 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 but may make such further inquiry or investigation into such facts and matters at it may see fit in its discretion and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled, upon reasonable notice to the Company, to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company. (a) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel or both. (b) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (c) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. (d) 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.

85 (e) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby. (f) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. (g) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as duties. (h) Except with respect to Section 4.01, the Trustee shall have no duty to inquire as to the performance of the Company with respect to the covenants contained in Article 4. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except (i) any Default or Event of Default occurring pursuant to paragraphs (1) or (2) of Section 6.01 or (ii) any Default or Event of Default of which the Trustee shall have received written notification. (i) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person employed to act hereunder. (j) Delivery of reports to the Trustee pursuant to Section 4.02 shall not constitute actual knowledge of, or notice to, the Trustee of the information contained therein. 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 or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company 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 send to each Holder 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 Holders.

86 SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with the May 15 following the date of this Indenture, and in any event prior to July 15 in each year, the Trustee shall mail to each Holder a brief report dated as of May 15 that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b). A copy of each report at the time of its mailing to Holders shall be filed with the SEC 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 such compensation for its services as the Company and the Trustee shall from time to time agree to in writing. 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 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 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, including the reasonable costs and expenses of defending itself against or investigating any claim or liability in connection with the exercise or performance of any of the Trustee’s rights, powers or duties hereunder (including the costs and expenses of enforcing this Indenture against the Company or the Subsidiary Guarantors (including this Section 7.07)). 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, 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 or the appointment of a successor Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) 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. The Holders of a majority in principal amount of

87 the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: (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. If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the 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 send a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 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 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 Holder 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

88 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. 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 Noteholder Collateral Agent, as the case may be, to execute and deliver the Intercreditor Agreement and the Security Documents in which the Trustee or the Noteholder 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 Noteholder 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 Noteholder 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 Discharge of Indenture; Defeasance SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a) When (1) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation, (2) all outstanding Securities have become due and payable, whether at maturity or on a redemption date as a result of the sending of a notice of redemption pursuant to Article 3 hereof or (3) all outstanding Securities not theretofore delivered for cancellation will become due and

89 payable within one year at their Stated Maturity or are to be called for redemption within one year, and, in the case of clause (2) or (3), the Company irrevocably deposits with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Securities, including interest thereon to maturity or such redemption date (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company (other than contingent indemnification obligations, if any, that, pursuant to the terms of this Indenture and the Security Documents, survive the termination thereof), then this Indenture and the Security Documents shall, subject to Section 8.01(c), cease to be of further effect, and the Company’s and Subsidiary Guarantors’ obligations under this Indenture and the Security Documents shall be satisfied and discharged. The Trustee shall acknowledge such satisfaction and discharge on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel (which, in the case of a redemption, may be the Officers’ Certificate and Opinion of Counsel related to such redemption) and at the cost and expense of the Company. (a) Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (1) all its obligations under the Securities and this Indenture (“legal defeasance option”) or (2) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 and the operation of clauses (4), (6), (7), (8), (9), (10) and (11) of Section 6.01 (but, in the case of clauses (7) and (8) with respect only to Significant Subsidiaries) and the limitations contained in Section 5.01(a)(3) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in clause (4), (5) (6), (7), (8), (9), (10) and (11) of Section 6.01 (but, in the case of clauses (7) and (8), with respect only to Significant Subsidiaries) or because of the failure of the Company to comply with Section 5.01(a)(3). If the Company exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor, if any, shall be released from all its obligations with respect to its Subsidiary Guarantee and the Security Documents. Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates. (b) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive, as well as contingent indemnification obligations, if any, that, pursuant to the terms of this Indenture and the Security Documents, survive the termination thereof.

90 SECTION 8.02. Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if: (1) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment of principal of and interest on the Securities to maturity or redemption, as the case may be; (2) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion (or, if two or more nationally recognized firms of independent accountants decline to issue such opinion after the Company has made reasonable efforts to obtain such an opinion, a certificate from the Company’s chief financial officer so stating and expressing such opinion) that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be; (3) 123 days pass after the deposit is made and during the 123-day period no Default specified in Sections 6.01(7) or (8) with respect to the Company occurs which is continuing at the end of the period; (4) the deposit does not constitute a default under any other agreement binding on the Company; (5) the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; (6) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such legal defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred; (7) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and

91 (8) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities as contemplated by this Article 8 have been complied with. Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3. SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities. SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time. Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Company for payment as general unsecured creditors. SECTION 8.05. Indemnity for Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and each Subsidiary Guarantor’s obligations under this Indenture, each Subsidiary Guarantee and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

92 Article 9 Amendments SECTION 9.01. Without Consent of Holders. The Company, the Subsidiary Guarantors, the Trustee and the Noteholder Collateral Agent may amend this Indenture, the Intercreditor Agreement, the Security Documents or the Securities without notice to or consent of any Holder: (1) to cure any ambiguity, omission, defect or inconsistency; (2) to comply with Article 5; (3) to provide for uncertificated Securities in addition to or in place of certificated Securities; provided, however, that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code); (4) to add Guarantees with respect to the Securities, including any Subsidiary Guarantee, or to secure the Securities or add collateral; (5) to add to the covenants of the Company or any Subsidiary Guarantor for the benefit of the Holders or to surrender any right or power herein conferred upon the Company or any Subsidiary Guarantor; (6) to make any change that does not adversely affect the rights of any Holder; (7) to comply with any requirement of the SEC in connection with qualifying, or maintaining the qualification of, this Indenture under the TIA; (8) to conform the text of this Indenture, the Intercreditor Agreement, the Securities, any Subsidiary Guarantee or any Security Document to any provision of the “Description of the notes” in the Offering Memorandum to the extent that such provision in the “Description of the notes” was intended to be a verbatim recitation of a provision of this Indenture, the Intercreditor Agreement, the Securities, such Subsidiary Guarantee or such Security Document; (9) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Securities; provided, however, that (a) compliance with this Indenture as so amended would not result in Securities being transferred in violation of the Securities Act or any other applicable securities law and (b) such amendment does not materially and adversely affect the rights of Holders to transfer Securities; or (10) to provide for the issuance of Additional Securities pursuant to a supplemental indenture in accordance with this Indenture.

93 After an amendment under this Section becomes effective, the Company shall send 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 an amendment under this Section. SECTION 9.02. With Consent of Holders. (a) The Company, the Subsidiary Guarantors, the Trustee and the Noteholder Collateral Agent may amend this Indenture, the Intercreditor Agreement, the Security Documents or the Securities with the written 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 the 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. (b) Notwithstanding Section 9.02(a), without the consent of each Holder affected thereby, an amendment or waiver may not: (1) reduce the amount of Securities whose Holders must consent to an amendment; (2) reduce the rate of or extend the time for payment of interest on any Security; (3) reduce the principal of or change the Stated Maturity of any Security; (4) change the provisions applicable to the redemption of any Security contained in Article 3 hereto or Section 5 or 6 of the Securities; (5) make any Security payable in money other than that stated in the Security; (6) impair the right of any Holder to receive payment of principal of and interest on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities; (7) make any change in Section 6.04 or 6.07 or this Section 9.02(b); (8) make any change in the ranking or priority of any Security that would adversely affect the Holders or 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 that would adversely affect such Holder; (9) make any change in, or release other than in accordance with this Indenture, any Subsidiary Guarantee that would adversely affect the Holders; or

94 (9) make any change in any Security Document, the Intercreditor Agreement or the provisions in this Indenture dealing with Security Documents or application of trust proceeds of the Collateral that would adversely affect the Holders. (c) Without the consent of the Holders of at least two-thirds in principal amount of 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 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 Noteholder Collateral Agent will be entitled to vote the total principal amount of Securities then outstanding as a block in respect of any vote required for such release under the Security Documents. (d) Clauses (4) and (6) of Section 9.02(b) and clauses (a) and (b) of Section 6.04 shall not apply to Sections 4.06 and 4.09, and amendments and waivers of such provisions and payments required thereunder shall be governed by Section 9.02(a). It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. (e) After an amendment under this Section becomes effective, the Company shall send 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 an amendment under this Section. 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 Holder. 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 Holders 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 of this Section 9.04, those Persons who were Holders at such record date (or their duly

95 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 and that such amendment is the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, and complies with the provisions of the Indenture. Such Opinion of Counsel shall be at the expense of the Company. SECTION 9.07. Payment for Consent. Neither the Company nor any Affiliate of the Company shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder 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 all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement. Article 10 Subsidiary Guarantees SECTION 10.01. Guarantees. Each Subsidiary 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 to the Noteholder Secured Parties under this Indenture, the Securities, the Intercreditor Agreement and the Security Documents and (b) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture, the Securities, the Intercreditor Agreement and the Security Documents (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary

96 Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor will remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation. Each Subsidiary 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 Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Subsidiary 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 Subsidiary Guarantor) under this Indenture, the Securities 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 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 Subsidiary Guarantor. Each Subsidiary Guarantor further agrees that its Subsidiary 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 and performance of the Guaranteed Obligations. Except as expressly set forth in Sections 8.01(a), 8.01(b), 10.02 and 10.06, the obligations of each Subsidiary 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 Subsidiary 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 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 Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity. Each Subsidiary 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.

97 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 Subsidiary 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 Subsidiary 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 Subsidiary 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 Subsidiary Guarantor’s Subsidiary 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 Subsidiary Guarantor for the purposes of this Section. Each Subsidiary 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 Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. SECTION 10.03. Successors and Assigns. This Article 10 shall be binding upon each Subsidiary 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

98 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 Subsidiary 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 Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances. SECTION 10.06. Release of Subsidiary Guarantor. A Subsidiary Guarantor will be released from its obligations under this Article 10: (1) upon the sale, transfer or other disposition (including by way of consolidation or merger) of a Subsidiary Guarantor, including the sale or disposition of Capital Stock of a Subsidiary Guarantor following which such Subsidiary Guarantor is no longer a Subsidiary; (2) upon the sale, transfer or disposition of all or substantially all the assets of such Subsidiary Guarantor; (3) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture; (4) upon the release or discharge of the Indebtedness that would have required such Subsidiary Guarantor to enter into a Guarantee Agreement pursuant to Section 4.12 other than a release or discharge by or as a result of the payment of such Indebtedness; (5) upon defeasance of the Securities pursuant to Article 8; or (6) upon the satisfaction and discharge of the Company’s obligations under this Indenture; provided, however, that in the case of clauses (1) and (2) above, (i) such sale or other disposition is made to a Person other than the Company or an Affiliate of the Company, (ii) such sale or disposition is otherwise permitted by this Indenture and (iii) the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations under Section 4.06. At the request of the Company, the Trustee shall execute and deliver an appropriate instrument evidencing such release. SECTION 10.07. Contribution. Each Subsidiary Guarantor that makes a payment under its Subsidiary Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata

99 portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP. Article 11 Security Documents SECTION 11.01. Collateral and Security Documents. (a) To secure the due and punctual payment and performance of the Obligations of the Company and the Subsidiary Guarantors to the Noteholder Secured Parties under this Indenture, the Securities, the Subsidiary Guarantees, the Intercreditor Agreement and the Security Documents, the Company, the Subsidiary Guarantors and the Noteholder Collateral Agent (on behalf of the Holders) have entered into, or will enter into, one or more Security Documents creating and establishing the Liens that secure such Obligations. The Trustee, the Noteholder Collateral Agent and the Company hereby acknowledge and agree that the Noteholder Collateral Agent holds the Collateral in trust on behalf of and for the benefit of the Noteholder Secured Parties, in each case pursuant to the terms of the Security Documents and subject to the terms of the Intercreditor Agreement. (b) Each Holder, by accepting a Security, agrees to all of the terms and provisions of the Security Documents and the Intercreditor Agreement, as the same may be amended from time to time pursuant to the terms thereof and this Indenture, and authorizes and directs the Noteholder 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; provided, however, that if any provisions of the Security Documents limit, qualify or conflict with the duties imposed by the provisions of the TIA, the TIA will control. The Trustee has appointed the Noteholder Collateral Agent as its agent under the Security Documents and the Intercreditor Agreement, and the Noteholder Collateral Agent is thereby authorized to act on behalf of the Trustee, with full authority and powers of the Trustee thereunder. SECTION 11.02. Recording; Annual Opinions; Reports. (a) The Company shall deliver to the Noteholder 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 11.02, to assure and confirm to the Noteholder Collateral Agent the first-priority Lien in the Notes Priority Collateral and the second-priority Lien in the ABL Priority Collateral contemplated hereby or 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 Subsidiary Guarantors to the Noteholder Secured Parties under this Indenture, the Securities, the Subsidiary Guarantees, the Intercreditor Agreement and the

SECTION 11.03. Non-Impairment of Liens. Any release of Collateral permitted by Section 11.04 shall be deemed not to impair the Liens under this Indenture and the Security Documents in contravention thereof. SECTION 11.04. Release of Collateral. (a) Collateral may be released from the Lien 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 the Collateral securing the Securities shall be immediately released with respect to the relevant Collateral under any one of more of the following circumstances: (1) to enable the Company or any Subsidiary Guarantor to sell, exchange or otherwise dispose of any of the Collateral to the extent not prohibited under Section 4.06; (2) in the case of a Subsidiary Guarantor that is released from its Subsidiary Guarantee with respect to the Securities, the release of the property and assets of such Subsidiary Guarantor; (3) pursuant to an amendment or waiver in accordance with Article 9; (4) pursuant to the terms of the Intercreditor Agreement; (5) if the Securities have been discharged or defeased pursuant to Article 8; or (6) upon the payment in full of the principal of, together with accrued and unpaid interest on, the Securities and all other Obligations of the Company and the Subsidiary Guarantors to the Noteholder Secured Parties under this Indenture, the Subsidiary Guarantees, the Intercreditor Agreement and the Security Documents that are then due and payable (other than contingent indemnification obligations, if any, that, pursuant to the terms of this Indenture and the Security Documents, survive the termination thereof); provided that in the case of any release in whole pursuant to clauses (1), (2) and (3) above, all amounts owing at such time to the Trustee under this Indenture, the

102 Securities, the Subsidiary Guarantees, the Security Documents and the Intercreditor Agreement have been paid (other than contingent indemnification obligations, if any, that, pursuant to the terms of this Indenture and the Security Documents, survive the termination thereof). (b) The second-priority Lien on the ABL Priority Collateral securing the Securities and the Subsidiary 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 Lien on the ABL Priority Collateral securing the Securities and the Subsidiary Guarantees shall also terminate and be released automatically and unconditionally 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). (c) To the extent applicable, the Company shall cause § 313(b) of the TIA, relating to reports, and § 314(d) of the TIA, relating to the release of property or securities from the Lien hereof and of the Security Documents to be complied with. Any certificate or opinion required by TIA § 314(d) may be made by an officer or legal counsel, as applicable, of the Company except in the cases where TIA § 314(d) requires that such certificate or opinion be made by an independent person, which Person will be an independent engineer, appraiser or other expert selected by or reasonably satisfactory to the Trustee. Notwithstanding anything to the contrary in this Section 11.04, the Company shall not be required to comply with all or any portion of TIA § 314(d) if it reasonably determines that, under the terms of TIA § 314(d) or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of TIA § 314(d) is inapplicable to any release or series of releases of Collateral. (d) In addition, and without limiting the generality of the foregoing, the Subsidiaries of the Company may, among other things, without any release or consent by the Trustee (and without the delivery of any Officers’ Certificate or any other documents under this Indenture, except as specified in this Section 11.04, but otherwise in compliance with the covenants of this Indenture and the Security Documents), conduct ordinary course activities with respect to the Collateral, including (i) selling or otherwise disposing of, in any transaction or series of related transactions, any property subject to the Liens created by this Indenture or any of the Security Documents which has become worn out, defective or obsolete or not used or useful in the business; (ii) abandoning, terminating, canceling, releasing or making alterations in or substitutions of any leases or contracts subject to the Liens created by the Security Documents; (iii) surrendering or modifying any franchise, license or permit subject to the Liens created by the Security Documents which it may own or under which it may be operating; (iv) altering, repairing,

(e) Starting with the fiscal year ending December 31, 2014, the Company shall deliver to the Trustee within 30 calendar days following the end of the fiscal year (or such later date as the Trustee shall agree), an Officers’ Certificate to the effect that all releases and withdrawals during the preceding fiscal year (or since the date of this Indenture, in the case of the first such certificate) in which no release or consent of the Trustee was obtained in the ordinary course of the Company’s and its Subsidiaries’ business were not prohibited by this Indenture. Notwithstanding any of the foregoing to the contrary, the Trustee shall execute and deliver to the Company all documents reasonably requested to evidence any such release of Collateral without any representation or warranty of any kind. In addition, in lieu of releasing the Liens created by any of the mortgages on Material Real Property, the Trustee or the Noteholder Collateral Agent will, at the request of the Company, to the extent necessary to facilitate future savings in connection with mortgage recording taxes in any state that imposes such taxes, assign such Lien to a new lender or collateral agent without any representation or warranty of any kind. SECTION 11.05. Suits To Protect the Collateral. Subject to the provisions of the Security Documents and the Intercreditor Agreement, the Trustee shall have power to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Security Documents, the Intercreditor Agreement or this Indenture, and such suits and proceedings as the Trustee, in its sole discretion, may deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Lien on the Collateral or be prejudicial to the interests of the Holders or the Trustee). SECTION 11.06. 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.

104 SECTION 11.07. Purchaser Protected. In no event shall any purchaser in good faith of any property purported to be released hereunder or under any Security Document be bound to ascertain the authority of 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 obligation to ascertain or inquire into the authority of the Company or the applicable Subsidiary Guarantor to make any such sale or other transfer. SECTION 11.08. 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 Subsidiary 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 Subsidiary 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 11.09. Release Upon Termination of the Company’s Obligations.

SECTION 11.10. Noteholder Collateral Agent. (a) By accepting a Security, each Holder shall be deemed to have irrevocably appointed the Noteholder Collateral Agent to act as its agent under the Security Documents and the Intercreditor Agreement and to have irrevocably authorized the Noteholder Collateral Agent to (i) perform the duties and exercise the rights, powers

105 and discretions that are specifically given to it under the Security Documents, the Intercreditor Agreement or other documents in respect of the Securities 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 Noteholder Collateral Agent on its behalf.

(d) Subject to Section 7.01, none of the Trustee, the Noteholder 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 Security 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 Noteholder 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, the Intercreditor Agreement or the Collateral. (f) In acting as Noteholder Collateral Agent, co-collateral agent or sub-collateral agent, the Noteholder 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. SECTION 11.11. 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

106 designation is set forth in writing, signed on behalf of the Company by an Officer and delivered to the Trustee, the Noteholder Collateral Agent and the Bank Collateral Agent.

The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of those terms.

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.

Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption will not impair or affect the validity of the redemption of any other Security redeemed in accordance with the provisions of the Indenture. Securities in denominations larger than $2,000 principal amount may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

Discharge and Defeasance Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its and the Subsidiary Guarantors’ obligations under the Securities, the Indenture and the Security Documents 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. 12.

11 13. Defaults and Remedies Under the Indenture, Events of Default include: (a) default for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption, upon acceleration or otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company or any Subsidiary Guarantor 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 grace period after final maturity) of other Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $20 million; (e) certain events of bankruptcy or insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $20 million; (g) certain defaults with respect to Subsidiary Guarantees; and (h) certain defaults relating to the Collateral under the Security Documents. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare 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. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 14. 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. 15. No Recourse Against Others A director, officer, employee or stockholder, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

26 13. Defaults and Remedies Under the Indenture, Events of Default include: (a) default for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon redemption, upon acceleration or otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company or any Subsidiary Guarantor 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 grace period after final maturity) of other Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary if the amount accelerated (or so unpaid) exceeds $20 million; (e) certain events of bankruptcy or insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $20 million; (g) certain defaults with respect to Subsidiary Guarantees; and (h) certain defaults relating to the Collateral under the Security Documents. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare 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. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders. 14. 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. 15. No Recourse Against Others A director, officer, employee or stockholder, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.
