The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.

Section 2.08. CUSIP and CINS Numbers. The Company in issuing the Notes may use “CUSIP” and “CINS” numbers, and the Trustee will use CUSIP numbers or CINS numbers in notices of redemption or exchange or in Offers to Purchase as a convenience to Holders, the notice to state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption or exchange or Offer to Purchase. The Company will promptly notify the Trustee in writing of any change in the CUSIP or CINS numbers.

Section 2.09. Registration, Transfer and Exchange. (a) The Notes will be issued in registered form only, without coupons, and the Company shall cause the Trustee to maintain a register (the “Register”) of the Notes, for registering the record ownership of the Notes by the Holders and transfers and exchanges of the Notes..

(b) (i) Each Global Note will be registered in the name of the Depositary or its nominee and, so long as DTC is serving as the Depositary thereof, will bear the DTC Legend.

(iii) Agent Members will have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, the Depositary or its nominee may grant proxies and otherwise authorize any Person (including any Agent Member and any Person that holds a beneficial interest in a Global Note through an Agent Member) to take any action which a Holder is entitled to take under this Indenture or the Notes, and nothing herein will

Table of Contents

impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a holder of any security.

(iv) If (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for a Global Note and a successor depositary is not appointed by the Company within 90 days of the notice or (y) an Event of Default has occurred and is continuing and the Trustee has received a request from the Depositary, the Trustee will exchange each beneficial interest in such Global Note for one or more Certificated Notes in authorized denominations having an equal aggregate principal amount registered in the name of the owner of such beneficial interest, as identified to the Trustee by the Depositary, and thereupon such Global Note will be deemed canceled. If such Note does not bear the Restricted Legend, then the Certificated Notes issued in exchange therefor will not bear the Restricted Legend. If such Note bears the Restricted Legend, then the Certificated Notes issued in exchange therefor will bear the Restricted Legend, provided that any Holder of any such Certificated Note issued in exchange for a beneficial interest in a Temporary Offshore Global Note will have the right upon presentation to the Trustee of a duly completed Certificate of Beneficial Ownership after the Restricted Period to exchange such Certificated Note for a Certificated Note of like tenor and amount that does not bear the Restricted Legend, registered in the name of such Holder.

(d) A Holder may transfer a Note (or a beneficial interest therein) to another Person or exchange a Note (or a beneficial interest therein) for another Note or Notes of any authorized denomination by presenting to the Trustee a written request therefor stating the name of the proposed transferee or requesting such an exchange, accompanied by any certification, opinion or other document required by Section 2.10. The Trustee will promptly register any transfer or exchange that meets the requirements of this Section by noting the same in the register maintained by the Trustee for the purpose; provided that

(i)no transfer or exchange will be effective until it is registered in such register and

(ii)the Trustee is not required (A) to issue, register the transfer of or exchange any Note for a period of 15 days before a selection of Notes to be redeemed or purchased pursuant to an Offer to Purchase, (B) to register the transfer of or exchange any Note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of the Note not being redeemed or purchased, or (C) if a redemption or a purchase pursuant to an Offer to Purchase is to occur after a Regular Record Date but on or before the corresponding Interest Payment Date, to register the transfer of or exchange any Note on or after the Regular Record Date and before the date of redemption or purchase. Prior to the registration of any transfer, the Company, the Trustee and their agents will treat the Person in whose name the Note is registered as the owner and Holder thereof for all purposes (whether or not the Note is overdue), and will not be affected by notice to the contrary.

From time to time the Company will execute and the Trustee will authenticate additional Notes as necessary in order to permit the registration of a transfer or exchange in accordance with this Section.

No service charge will be imposed in connection with any registration of transfer or exchange of any Note, but the Company or the Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than a transfer tax or other similar governmental charge payable upon exchange pursuant to subsection (b)(iv)).

A Restricted Subsidiary required to provide a Note Guarantee shall execute a supplemental indenture substantially in the form of Exhibit B hereto, and deliver an Opinion of Counsel to the Trustee to the effect that the supplemental indenture has been duly authorized, executed and delivered by the Restricted Subsidiary and constitutes a valid and binding obligation of the Restricted Subsidiary, enforceable against the Restricted Subsidiary in accordance with its terms (subject to customary exceptions).

Section 4.12. Repurchase of Notes upon a Change of Control. Not later than 30 days following a Change of Control, the Company will make an Offer to Purchase all outstanding Notes at a purchase price equal to 101% of the principal amount plus accrued interest to the date of purchase.

Table of Contents

pledged as Collateral under the Collateral Agreements substantially simultaneously with such sale, in accordance with the requirements set forth in this Indenture.

For purposes of this clause (b):

(i)Debt (other than Subordinated Debt) or other obligations of the Company or a Restricted Subsidiary assumed by the purchaser pursuant to a customary novation agreement, and

(ii)instruments or securities received from the purchaser that are promptly, but in any event within 30 days of the closing, converted by the Company to cash, to the extent of the cash actually so received

shall be considered cash received at closing.

(c)An amount equal to the Net Cash Proceeds from the Asset Sale may be used

(i)to permanently repay (1) any First Lien Indebtedness or (2) unless the Net Cash Proceeds are from a disposition of Collateral, Debt under the Credit Agreement, or (3) unless the Net Cash Proceeds are from a disposition of Collateral, Debt of any Restricted Subsidiary that is not a Guarantor (and, in each case, in the case of a revolving credit, permanently reduce the commitment thereunder by such amount), or

(ii)to acquire all or substantially all of the assets of a Permitted Business, or a majority of the Voting Stock of another Person that thereupon becomes a Restricted Subsidiary engaged in a Permitted Business, or to make capital expenditures or otherwise acquire long-term assets (including an undivided interest therein) that are to be used in a Permitted Business; provided that the assets (including Voting Stock) acquired with the Net Cash Proceeds of a disposition of Collateral are pledged as Collateral under the Collateral Agreements substantially simultaneously with such acquisition in accordance with the requirements of this Indenture.

(i)the accumulated Excess Proceeds, multiplied by

(ii)a fraction (x) the numerator of which is equal to the outstanding principal amount of the Notes and (y) the denominator of which is equal to the outstanding principal amount of the Notes and all Parity Lien Debt similarly required to be repaid, redeemed or tendered for in connection with the Asset Sale,

rounded down to the nearest $1,000. The purchase price for the Notes will be 100% of the principal amount plus accrued interest to the date of purchase. Upon completion of the Offer to Purchase, Excess Proceeds will be reset at zero, and any Excess Proceeds remaining after consummation of the Offer to Purchase may be used for any purpose not otherwise prohibited by this Indenture.

(e)To the extent that any Net Cash Proceeds are from a disposition of Collateral the fair market value of which exceeds $20.0 million in the aggregate, such Net Cash Proceeds will be deposited with the Noteholder Collateral Agent or the Trustee, as the case may be, and held as Collateral pending application

The Company will not, and will not permit any of its Restricted Subsidiaries, to engage in any business other than a Permitted Business (including indirectly, through its interest in a Joint Venture that is not a Restricted Subsidiary), except to an extent that so doing would not be material to the Company and its Restricted Subsidiaries, taken as a whole.

Section 4.16. Designation of Restricted and Unrestricted Subsidiaries. (a) The Board of Directors may designate any Subsidiary, including a newly acquired or created Subsidiary, to be an Unrestricted Subsidiary if it meets the following qualifications and the designation would not cause a Default:

(i)grant Liens on such property (or, in the case of a new Guarantor, all of its assets constituting the type that is Collateral) in favor of the Noteholder Collateral Agent for the benefit of the holders of Second-Priority Lien Obligations (and, to the extent such grant would require the execution and delivery of a Collateral Agreement, the Company or such Guarantor shall execute and deliver such Collateral Agreement on substantially the same terms as the Collateral Agreements covering Collateral owned by the Company or a Guarantor on the Issue Date including, with respect to personal property, execution of a supplement to the Security Agreement and, with respect to real property, execution of a new Mortgage or an amendment to an existing Mortgage);

(ii)deliver certain Opinions of Counsel and certificates in respect thereof as required by the Collateral Agreements and, in the case of real property, a Title Insurance Policy, an Opinion of Counsel addressing customary matters and containing customary exceptions and either (A) an ALTA/ACSM or otherwise customary survey or (B) such documentation as is sufficient to omit the standard survey exception to coverage under the Title Insurance Policy with respect to such real property and grant such affirmative endorsements to such Title Insurance Policy as are customary; and

(iii)cause the Lien granted in such Collateral Agreement to be duly perfected to the same extent as the Liens granted on Collateral owned by the Company or a Guarantor on the Issue Date are perfected (including, with respect to Equity Interests of a Subsidiary or intercompany debt, perfection by control to the extent required by the Security Agreement);

provided that no such Liens have to be granted over any Excluded Property.

The Company or such Guarantor shall deliver an Opinion of Counsel to the Trustee to the extent required by §314(b) of the TIA in respect of any Xxxx xxxxx referred to in this clause (b).

(c) The Company will bear and pay all legal expenses, collateral audit and valuation costs, filing and recording fees, survey costs, insurance premiums and other costs associated with the performance of

the obligations of the Company and the Guarantors set forth in this Section 4.19 and will also pay or reimburse the Trustee and Noteholder Collateral Agent for all reasonable out-of-pocket expenses, disbursements and advances incurred or made by the Trustee and Noteholder Collateral Agent in connection therewith, including the reasonable compensation and expenses of the Trustee and Noteholder Collateral Agent's agents and counsel.

(e) Neither the Company nor any of the Guarantors will be permitted to take any action, 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 Trustee and the Holders of the Notes.

Upon satisfaction of the conditions described above, the Company may omit to comply with the covenants and clauses described above and shall have no liability in respect thereof, including by reason of any reference to such covenants or clauses elsewhere in this Indenture. Except as specifically stated above, none of the Company's obligations under this Indenture will be discharged.

Section 8.04. Application of Trust Money. Subject to Section 8.05 the Trustee will hold in trust the money or U.S. Government Obligations deposited with it pursuant to Section 8.01, 8.02 or 8.03, and apply the deposited money and the proceeds from deposited U.S. Government Obligations to the payment of principal of and interest on the Notes in accordance with the Notes and this Indenture. Such money and U.S. Government Obligations need not be segregated from other funds except to the extent required by law.

Section 8.05. Repayment to Company. Subject to Sections 7.07, 8.01, 8.02 and 8.03, the Trustee will promptly pay to the Company upon request any excess money held by the Trustee at any time and thereupon be relieved from all liability with respect to such money. The Trustee will pay to the Company upon request any money held for payment with respect to the Notes that remains unclaimed for two years, provided that before making such payment the Trustee may at the expense of the Company publish once in a newspaper of general circulation in New York City, or send to each Holder entitled to such money, notice that the money remains unclaimed and that after a date specified in the notice (at least 30 days after the date of the publication or notice) any remaining unclaimed balance of money will be repaid to the

Company. After payment to the Company, Holders entitled to such money must look solely to the Company for payment, unless applicable law designates another Person, and all liability of the Trustee with respect to such money will cease.

Section 8.06. Reinstatement. If and for so long as the Trustee is unable to apply any money or U.S. Government Obligations held in trust pursuant to Section 8.01, 8.02 or 8.03 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 obligations under this Indenture and the Notes and the Guarantors' obligations under this Indenture and the Note Guarantees will be reinstated as though no such deposit in trust had been made. If the Company makes any payment of principal of or interest on any Notes because of the reinstatement of its obligations, it will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held in trust.

Table of Contents

Guarantor by Liens on the Collateral pursuant to the Collateral Agreements if such Debt is permitted to be Incurred and secured by such Liens under this Indenture, or (b) to evidence the requisite priorities of the Liens granted by the Collateral Agreements and any other Permitted Liens on the Collateral.

Section 9.02. Amendments with Consent of Holders. (a) Except as otherwise provided in Sections 6.02, 6.04, and 6.07 or paragraph (b), the Company and the Trustee (and, in the case of the Collateral Agreements, the Noteholder Collateral Agent) may amend this Indenture, the Notes and/or the Collateral Agreements with the written consent of the Holders of a majority in principal amount of the then outstanding Notes, and the Holders of a majority in principal amount of the then outstanding Notes by written notice to the Trustee may waive future compliance by the Company with any provision of this Indenture, the Notes or the Collateral Agreements.

(b) Notwithstanding the provisions of paragraph (a), without the consent of each Holder affected, an amendment or waiver may not

It is not necessary for Noteholders to approve the particular form of any proposed amendment, supplement or waiver, but is sufficient if their consent approves the substance thereof.

Table of Contents

(c) An amendment, supplement or waiver under this Section becomes effective on receipt by the Trustee of written consents from the Holders of the requisite percentage in principal amount of the outstanding Notes. After an amendment, supplement or waiver under this Section becomes effective, the Company will send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. The Company will send supplemental indentures to Holders upon request. Any failure of the Company to send such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

Section 9.03. Effect of Consent. (a) After an amendment, supplement or waiver becomes effective, it will bind every Holder unless it is of the type requiring the consent of each Holder affected. If the amendment, supplement or waiver is of the type requiring the consent of each Holder affected, the amendment, supplement or waiver will bind each Holder that has consented to it and every subsequent Holder of a Note that evidences the same debt as the Note of the consenting Holder.

(b) If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder to deliver it to the Trustee so that the Trustee may place an appropriate notation of the changed terms on the Note and return it to the Holder, or exchange it for a new Note that reflects the changed terms. The Trustee may also place an appropriate notation on any Note thereafter authenticated. However, the effectiveness of the amendment, supplement or waiver is not affected by any failure to annotate or exchange Notes in this fashion.

Section 9.04. Trustee's Rights and Obligations. The Trustee is entitled to receive, and will be fully protected in relying upon, in addition to the documents required by Section 13.04, an Officers' Certificate and an Opinion of Counsel each stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article is authorized or permitted by this Indenture. If the Trustee has received such an Officers' Certificate and an Opinion of Counsel, it shall sign the amendment, supplement or waiver so long as the same does not adversely affect the rights of the Trustee. The Trustee may, but is not obligated to, execute any amendment, supplement or waiver that affects the Trustee's own rights, duties or immunities under this Indenture.

Section 9.05. Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act.

Section 9.06. Payments for Consents. Neither the Company nor any of its Subsidiaries or Affiliates may, 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 Notes unless such consideration is offered to be paid or agreed to be paid to all Holders of the Notes that consent, waive or agree to amend such term or provision within the time period set forth in the solicitation documents relating to the consent, waiver or amendment.

GUARANTEEES

Section 10.01 The Guarantees . Subject to the provisions of this Article, each Guarantor hereby irrevocably and unconditionally guarantees, jointly and severally, the full and punctual payment (whether at Stated Maturity, upon redemption, purchase pursuant to an Offer to Purchase or acceleration, or otherwise) of the principal of, premium, if any, and interest on, and all other amounts payable under, each Note, and the full and punctual payment of all other amounts payable by the Company under this

Table of Contents

Indenture. Upon failure by the Company to pay punctually any such amount, each Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Indenture.

Section 10.02 Guarantee Unconditional. The obligations of each Guarantor hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under this Indenture or any Note, by operation of law or otherwise;

(b) any modification or amendment of or supplement to this Indenture or any Note;

(c) any change in the corporate existence, structure or ownership of the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or its assets or any resulting release or discharge of any obligation of the Company contained in this Indenture or any Note;

(d) the existence of any claim, set-off or other rights which the Guarantor may have at any time against the Company, the Trustee or any other Person, whether in connection with this Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

(e) any invalidity or unenforceability relating to or against the Company for any reason of this Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the principal of or interest on any Note or any other amount payable by the Company under this Indenture; or

(f) any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Guarantor's obligations hereunder.

Section 10.03 Discharge; Reinstatement. Each Guarantor's obligations hereunder will remain in full force and effect until the principal of, premium, if any, and interest on the Notes and all other amounts payable by the Company under this Indenture have been paid in full. If at any time any payment of the principal of, premium, if any, or interest on any Note or any other amount payable by the Company under this Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guarantor's obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

Section 10.04 Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

Section 10.05 Subrogation and Contribution. Upon making any payment with respect to any obligation of the Company under this Article, the Guarantor making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that the Guarantor may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so long as any amount payable by the Company hereunder, or under the Notes remains unpaid.

Table of Contents

Section 10.06 Stay of Acceleration. If acceleration of the time for payment of any amount payable by the Company under this Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of this Indenture are nonetheless payable by the Guarantors hereunder forthwith on demand by the Trustee or the Holders.

Section 10.07 Limitation on Amount of Guarantee. Notwithstanding anything to the contrary in this Article, each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Note Guarantee are limited to the minimum amount that would not render the Guarantor's obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

Section 10.08 Execution and Delivery of Guarantee. The execution by each Guarantor of this Indenture (or a supplemental indenture substantially in the form of Exhibit B) evidences the Note Guarantee of such Guarantor, whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in this Indenture on behalf of each Guarantor.

Section 10.09 Release of Guarantee. The Note Guarantee of a Guarantor will terminate upon

(a) a sale or other disposition (including by way of consolidation or merger) of the Guarantor or the sale or disposition of all or substantially all the assets of the Guarantor (in each case other than to the Company or a Restricted Subsidiary) otherwise permitted by this Indenture,

(b) the designation in accordance with this Indenture of the Guarantor as an Unrestricted Subsidiary, or

Upon delivery by the Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to the foregoing effect, the Trustee will execute any documents reasonably required in order to evidence the release of the Guarantor from its obligations under its Note Guarantee.

RANKING OF LIENS

Section 11.01 Agreement for the Benefit of Holders of First-Priority Liens. The Trustee and the Noteholder Collateral Agent agree, and each Holder of the Notes by accepting a Note, agrees:

(a) So long as no First Lien Indebtedness is outstanding, upon the occurrence and during the continuance of an Event of Default, the Noteholder Collateral Agent will be permitted (together with the representative of any other Debt secured by parity Liens on the Collateral), to take steps with respect to remedies and enforcement, acting at the direction of the Applicable Authorized Representative. On the

Table of Contents

Issue Date, the Trustee, acting at the written direction of the Holders of a majority in principal amount of the Notes, will be the Applicable Authorized Representative.

(b) If First Lien Indebtedness is incurred, the Noteholder Collateral Agent will, and is hereby authorized to, at such time enter into an Intercreditor Agreement substantially in the form of Exhibit J attached to this Indenture, which will establish the subordinate priority status of the Second-Priority Liens and to take all steps to effectuate such agreement, provided that, with respect to any real property subject to a Mortgage, if subordination of such Mortgage to the First Priority Liens is required and any Liens that secure a monetary obligation of the Company or a Guarantor (other than any judgment Lien with respect to which no judgment default has occurred and is continuing) have been recorded against such real property after the recording of the applicable Mortgage, such Liens shall be either released of record or similarly subordinated to the First Priority Liens in connection with any such subordination of the applicable Mortgage. This Indenture, Notes, Note Guarantees and Collateral Agreements will at such time be subject to the Intercreditor Agreement.

Section 11.02 Notes, Guarantees and Other Second-Priority Lien Obligations Not Subordinated. The provisions of this Article 11 are intended solely to set forth the relative ranking, as Liens, of the Second-Priority Liens as against the First-Priority Liens. The Notes and Note Guarantees are senior non-subordinated Obligations of the Company and Guarantors. Neither the Notes, the Note Guarantees and other Second-Priority Lien Obligations nor the exercise or enforcement of any right or remedy for the payment or collection thereof (other than the exercise of rights and remedies of a secured party, which are subject to the Intercreditor Agreement) are intended to be or will ever be, by reason of the provisions of this Article 11, in any respect subordinated, deferred, postponed, restricted or prejudiced.

Section 11.03 Relative Rights. The Intercreditor Agreement defines the relative rights, as lienholders, of holders of Second-Priority Liens and holders of First-Priority Liens. Nothing in this Indenture or the Intercreditor Agreement will:

(a) impair, as between the Company and Holders, the obligation of the Company, which is absolute and unconditional, to pay principal of, premium and interest on the Notes in accordance with their terms or to perform any other obligation of the Company or any other obligor under this Indenture, Notes, Note Guarantees and Collateral Agreements;

(b) restrict the right of any Holder to xxx for payments that are then due and owing;

(c) prevent the Trustee, the Noteholder Collateral Agent or any Holder from exercising against the Company or any other obligor any of its other available remedies upon a Default or Event of Default (other than its rights as a secured party, which are subject to the Intercreditor Agreement); or

(d) restrict the right of the Trustee, the Noteholder Collateral Agent or any Holder:

(1) to file and prosecute a petition seeking an order for relief in an involuntary bankruptcy case as to any obligor or otherwise to commence, or seek relief commencing, any insolvency or liquidation proceeding involuntarily against any obligor;

(2) to make, support or oppose any request for an order for dismissal, abstention or conversion in any insolvency or liquidation proceeding;

Table of Contents

(3) to make, support or oppose, in any insolvency or liquidation proceeding, any request for an order extending or terminating any period during which the debtor (or any other Person) has the exclusive right to propose a plan of reorganization or other dispositive restructuring or liquidation plan therein;

(4) to seek the creation of, or appointment to, any official committee representing creditors (or certain of the creditors) in any insolvency or liquidation proceedings and, if appointed, to serve and act as a member of such committee without being in any respect restricted or bound by, or liable for, any of the obligations under this Article 11;

(5) to seek or object to the appointment of any professional person to serve in any capacity in any insolvency or liquidation proceeding or to support or object to any request for compensation made by any professional person or others therein;

(6) to make, support or oppose any request for an order appointing a trustee or examiner in any insolvency or liquidation proceedings; or

(7) otherwise to make, support or oppose any request for relief in any insolvency or liquidation proceeding that it is permitted by law to make, support or oppose:

(x) if it were a holder of unsecured claims; or

(y) as to any matter relating to any plan of reorganization or other restructuring or liquidation plan or as to any matter relating to the administration of the estate or the disposition of the case or proceeding;

in each case, except as set forth in the Intercreditor Agreement.

(c)Following an Event of Default, subject to the provisions of Section 7.01, Section 7.02, Article 11 and the Intercreditor Agreement, the Trustee may (but without any obligation to do so), in its sole discretion and without the consent of the Holders, direct, on behalf of the Holders, the Noteholder Collateral Agent to take all actions it deems necessary or appropriate in order to:

Section 12.05. Release Of Liens.

(a)The Liens will be released, with respect to the Notes and the Guarantees:

(i)in whole, upon payment in full of the principal of, accrued and unpaid interest and premium, if any, on the Notes and payment in full of all other Obligations in respect thereof that are due and payable at or prior to the time such principal, accrued and unpaid interest and premium, if any, on the Notes are paid;

Notwithstanding anything to the contrary herein, the Company and the Guarantors will not be required to comply with all or any portion of TIA §314(d) if they determine, in good faith based on advice of counsel (which may be internal counsel), that under the terms of that section and/or any interpretation or guidance as to the meaning thereof of the Commission and its staff, including “no action” letters or exemptive orders, all or any portion of TIA §314(d) is inapplicable to the released Collateral.

J-6

Table of Contents

Parity Lien Collateral Agent may retain a junior lien on such assets subject to the terms hereof to the extent permitted under applicable law).

Section 2.04. Perfection of Liens. Except as expressly provided in Section 5.05(a), (i) none of the First-Lien Agent or the Senior Lenders shall be responsible for perfecting and maintaining the perfection of Liens with respect to the Common Collateral for the benefit of the Trustee, any other agent, trustee or other representative for Parity Lien Debt, the Parity Lien Collateral Agent and the Noteholders and (ii) none of the Trustee, the Parity Lien Collateral Agent, any other agent, trustee or other representative for Parity Lien Debt or the Noteholders shall be responsible for perfecting and maintaining the perfection of Liens with respect to the Common Collateral for the benefit of the First-Lien Agent or the Senior Lenders.

Section 2.05. [reserved]

Section 2.06. Recording of Liens. The Parity Lien Collateral Agent, on behalf of itself and each of the Trustee, any other agent, trustee or representative for Parity Lien Debt, and the Noteholders, agrees that until the prior Lien of the Senior Lenders on any Common Collateral has been recorded or otherwise perfected, it will take commercially reasonable efforts not to file or to otherwise perfect a Lien against such Common Collateral (other than steps taken prior to the date hereof).

The First-Lien Agent will use commercially reasonable efforts to record or otherwise perfect its security interest in the Common Collateral as promptly as practicable.

Article III.Enforcement.

Section 3.01. Exercise of Remedies.

Fourth: Any surplus then remaining shall be paid to the Company or the respective Grantor, its successors or assigns, or as a court of competent jurisdiction may direct.

In connection with the application of proceeds pursuant to this Section 4(d), except as otherwise directed in writing by the Applicable Authorized Representative, the Collateral Agent may sell any non-cash proceeds for cash prior to the application of the proceeds thereof.
