THE NOTES

Section 2.01. Form and Dating; Terms.

(a) General. The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes will only be issued as Definitive Notes. The Notes may have notations, legends or endorsements required by law, stock exchange rules or usage. Each Note shall be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof (or if a PIK Note Payment has been made, the Notes shall be in minimum denominations of $1.00 and any integral multiple of $1.00 in excess thereof).

(b) Terms. The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture on the Issue Date is $300,000,000.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

If the Issuer is permitted to pay PIK Interest in respect of the Notes (upon the terms and conditions set forth in clause (c) below), and the Issuer elects to pay such PIK Interest through the issuance of Notes, the Issuer will issue new Notes (the “PIK Notes”). The Initial Notes and any PIK Notes shall be substantially identical other than the issuance dates, offering price, minimum denominations, transfer restrictions and, if applicable, the date from which interest shall accrue. The payment of interest on the Notes through PIK Note Payments or through the issuance of Common Stock (the “PIK Shares”) is herein referred to as “PIK Interest.”

The Initial Notes and any PIK Notes will be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase.

-55-

(i) Cash Interest Payments. Except as provided in this Section 2.01(c), interest on the outstanding principal amount of the Notes shall be payable entirely in cash (such interest, “Cash Interest”) on the relevant Interest Payment Date.

(ii) PIK Interest Payments. Subject to the restrictions in clause (iii) below, the Issuer may elect, at its option, to pay all or a portion of the interest due on the Notes on the applicable Interest Payment Date by (1) issuing PIK Shares to the Holders (such payments, “PIK Share Payments”) or (2) issuing PIK Notes (such payments, “PIK Note Payments”) and, in each case, notifying the Trustee of such election pursuant to Section 2.01(c)(viii). The Issuer’s ability to elect to pay PIK Interest as PIK Share Payments is subject to the following conditions: (A) the Issuer shall have received the Requisite Shareholder Approvals, (B) the PIK Share Payment shall not result in a beneficial owner of the Notes, such beneficial owner’s Affiliates and any person subject to aggregation with such beneficial owner or its Affiliates under Sections 13(d) and 14(d) of the Exchange Act), beneficially owning (as defined in Rules 13d-3 or 13d-5 under the Exchange Act, except that for purposes of this clause (B) such holder shall be deemed to have “beneficial ownership” of all shares that any such holder has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the Issuer or any of its direct or indirect parent entities (or their successors by merger, consolidation or purchase of all or substantially all of their assets), (C) the number of PIK Shares to be issued shall not be in excess of the authorized amount of Common Stock available under the Issuer’s charter therefor, (D) the PIK Shares shall be (x) listed on the New York Stock Exchange or any other exchange on which the Common Stock is then listed or the over the counter market and (y) duly authorized, validly issued and non-assessable, and the issuance of such PIK Shares shall not be subject to any preemptive or similar rights and (E) the Issuer’s Resale Registration Statement shall have been declared effective by the SEC subject to the requirements of the Registration Rights Agreement. If the foregoing conditions are not met and the Issuer otherwise has the ability to elect to pay PIK Interest, the Issuer may pay such PIK Interest as PIK Note Payments.

(iii) For any Interest Payment Date on or prior to December 31, 2018, the Issuer shall be permitted to pay PIK Interest in its sole discretion. For any Interest Payment Date after December 31, 2018, if the Liquidity for such Interest Period shall:

(1) equal or exceed $225.0 million, then the Issuer must pay Cash Interest on 100% of the principal amount of Notes outstanding, payable at the applicable Cash Interest Rate, and no PIK Interest may be paid;

(2) equal or exceed $200.0 million but be less than $225.0 million, then the Issuer may, at its option, elect to pay interest on (x) 25% of the then outstanding principal amount of the Notes as PIK Interest, payable at the applicable PIK Interest Rate, and (y) 75% of the then outstanding principal amount of the Notes as Cash Interest, payable at the applicable Cash Interest Rate;

(3) equal or exceed $175.0 million but be less than $200.0 million, then the Issuer may, at its option, elect to pay interest on (x) 50% of the then outstanding principal amount of the Notes as PIK Interest, payable at the applicable PIK Interest Rate, and (y) 50% of the then outstanding principal amount of the Notes as Cash Interest, payable at the applicable Cash Interest Rate;

-56-

(5) be less than $150.0 million, then the Issuer shall be permitted to pay PIK Interest on 100% of the principal amount of Notes outstanding, payable at the applicable PIK Interest Rate.

(iv) Cash Interest Rate. Cash Interest on the Notes shall accrue at a rate of 8.0% per annum and be payable in cash; provided that if the Requisite Shareholder Approvals are not obtained on or prior to the Requisite Shareholder Approval Deadline, Cash Interest on the Notes shall accrue at a rate of 15.0% per annum and be payable in cash; provided further that upon the occurrence and during the continuance of an Event of Default, the rate at which Cash Interest on the Notes accrues shall increase by an additional 2.0% per annum (the “Cash Interest Rate”). In the event the Requisite Shareholder Approvals are not obtained on or prior to the Requisite Shareholder Approval Deadline, the Issuer shall promptly provide written notice of such event to the Trustee and the Paying Agent.

(v) PIK Interest Rate. Any PIK Interest on the Notes shall accrue at a rate of 11.0% per annum; provided that if the Requisite Shareholder Approvals are not obtained on or prior to the Requisite Shareholder Approval Deadline, PIK Interest on the Notes shall accrue at a rate of 20.0% per annum; provided further that upon the occurrence and during the continuance of an Event of Default, the rate at which PIK Interest on the Notes accrues shall increase by an additional 2.0% per annum (the “PIK Interest Rate”).

(vi) Payment of PIK Interest.

(1) PIK Interest shall be payable in PIK Shares in an amount calculated by the Issuer by dividing the outstanding balance of the accrued PIK Interest after giving effect to any interest to be paid in Cash Interest on the outstanding principal amount of the Notes by the 20-day volume weighted average price per share of the Issuer’s Common Stock on the New York Stock Exchange (or the over-the-counter market or other exchange on which the Common Stock is then listed) calculated as at the end of the three Trading Days prior to the Determination Date, rounded up to the nearest share of Common Stock. With respect to any PIK Share Payments, the Issuer shall deliver such PIK Shares in payment of PIK Interest to the Holders on the relevant Interest Payment Date. On the relevant Interest Payment Date, the Issuer shall deliver to the Trustee an Officers’ Certificate certifying that the issuance of PIK Shares as payment of all or a portion of PIK Interest on such Interest Payment Date has been made in accordance with the Indenture and Officers’ Certificate delivered to the Trustee with respect to such Interest Payment Date pursuant to Section 2.01(c)(viii).

-57-

(2) PIK Note Payments shall be effected by issuing PIK Notes in certificated form in an aggregate principal amount equal to the percentage of PIK Interest to be paid on the principal amount of Notes held by each Holder on the relevant Record Date, after giving effect to any interest to be paid in Cash Interest, less any PIK Share Payment to be made on such Interest Payment Date (rounded up to the nearest $1.00), and the Trustee will, upon receipt of an Authentication Order, authenticate and deliver such PIK Notes on the Interest Payment Date in certificated form for original issuance to the Holders of record on the relevant Record Date, as shown in the Note Register.

(3) Any PIK Notes will be dated as of the applicable Interest Payment Date and will bear interest from and after such date. All Notes issued pursuant to a PIK Note Payment will mature on March 20, 2022 and will be governed by, and subject to, the terms, provisions and conditions of this Indenture and shall have the same rights and benefits as the Initial Notes. Following an increase in the principal amount of the outstanding Notes as a result of a PIK Note Payment, the Notes shall accrue interest on such increased principal amount from and after the related Interest Payment Date on which such PIK Notes were issued.

(4) PIK Share Payments shall be made by the Issuer to the respective Holders and certified to the Trustee in accordance with Sections 2.01(c)(vi)(1).

(5) In the event that the Issuer is permitted to and elects to pay a portion of the interest on the Notes as Cash Interest and a portion as PIK Interest, such Cash Interest and PIK Interest shall be paid to Holders pro rata in accordance with their interests; provided that if the Issuer determines, in its sole discretion, that any PIK Share Payment would cause the condition in clause (c)(ii)(B) above to not be met, then the Issuer may elect, upon the prior written consent of the Eligible Holders representing a majority of the principal amount of Notes held by such Eligible Holders, to issue the maximum PIK Share Payments to the Holders of Notes (which need not be on a pro rata basis) such that the condition in clause (c)(ii)(B) would continue to be satisfied following the issuance of such PIK Shares and any remaining interest due after giving effect to such election shall be paid by the Issuer in PIK Notes. The Issuer shall provide the Trustee and the Holders with notice of any election pursuant to this Section 2.01(c)(vi)(5) at least five (5) Business Days’ prior to the applicable Interest Payment Date. Notwithstanding anything to the contrary contained herein, the Issuer shall not make PIK Payments on the Notes if any cash interest is paid pursuant to the 1.75 Lien Credit Agreement; provided, however, that the Issuer will be permitted to pay Cash Interest under the 1.75 Lien Credit Agreement solely to the extent any payment of interest in shares of Common Stock under the 1.75 Lien Credit Agreement would cause the condition in the 1.75 Lien Credit Agreement analogous to the condition set forth in clause (c)(ii)(B) not to be met and provided, further, however, that the Issuer shall be permitted to pay cash interest on the 1.75 Lien Credit Agreement for the interest payment due on June 20, 2017 and will not be required to pay cash interest on the Notes for the initial Interest Payment Date as a result thereof.

-58-

(vii) The insufficiency or lack of funds available to the Issuer to pay Cash Interest as required pursuant to this Section 2.01(c) shall not permit the Issuer to pay PIK Interest in respect of any Interest Payment Date and the sole right of the Issuer to elect to pay PIK Interest shall be subject to the terms and conditions set forth in Section 2.01(c)(ii) and (iii).

(viii) No later than the twentieth (20th)day prior to each Interest Payment Date, the Issuer shall deliver to the Trustee and the Paying Agent (if other than the Trustee) an Officers’ Certificate certifying (i) that the Issuer is permitted to pay PIK Interest in the amounts set forth in the notice on the Next Interest Payment Date in accordance with the Indenture and is electing to pay PIK Interest on the next Interest Payment Date, (ii) the amount of interest to be paid on the next Interest Payment Date, (iii) the amount of PIK Interest to be paid as PIK Notes, if any, on the next Interest Payment Date, (iv) the amount of PIK Interest to be paid as PIK Shares, if any, on the next Interest Payment Date and the number of PIK Shares, if any, to be issued in connection therewith and (v) if Cash Interest and PIK Interest will not be paid to the Holders on a pro rata basis, that the Issuer is electing to make such payments in accordance with Section 2.01(c)(vi)(5) hereof and the amount of Cash Interest, amount of PIK Notes and number of PIK Shares (and the amount of PIK Interest represented by such PIK Shares), as applicable, to be paid to each Holder on the next Interest Payment Date. The Trustee shall promptly deliver a copy of such notice to the Holders.

(ix) Notwithstanding anything to the contrary, the payment of accrued and unpaid interest through the redemption or repurchase date in connection with any redemption or repurchase of the Notes as described under Sections 3.07, 4.10 and 4.14 shall be payable solely in cash at the applicable interest rate for such Interest Period or portion thereof.

(x) In the event that any PIK Share Payment is made, the Issuer shall use its best efforts to keep a Resale Registration Statement continuously effective until such time as no PIK Shares are held by any Holder, subject to any rights to delay or suspend or limit such registration pursuant to the Registration Rights Agreement.

(xi) Interest shall be computed on the basis of a 360-day year comprised of twelve (12) 30-day months.

Section 2.02. Execution and Authentication.

The signature shall be conclusive evidence that the Note has been duly authenticated and delivered under this Indenture.

-59-

On the Issue Date, the Trustee shall, upon receipt of an Issuer Order (an “Authentication Order”), authenticate and deliver the Initial Notes.

In addition, in connection with the election to pay PIK Interest (upon the terms and conditions set forth herein and in the Notes), the Issuer may deliver PIK Notes executed by the Issuer to the Trustee for authentication, together with an Authentication Order for authentication and delivery of PIK Notes, specifying the principal amount of and Holder of each Note, directing the Trustee to authenticate the PIK Notes and deliver the same to the persons in such order certifying the issuance of such Notes is permitted under this Indenture and the Trustee in accordance with such Authentication Order shall authenticate and deliver such PIK Notes.

Notwithstanding anything to the contrary in this Indenture, if a PIK Note Payment has been made, the Notes shall be in minimum denominations of $1.00 and any integral multiple of $1.00 in excess thereof.

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes 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 an Agent to deal with Holders or an Affiliate of the Issuer.

Section 2.03. Registrar and Paying Agent.

The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes (including the name and address of each Holder, and such Holder’s right to the principal of, and sated interest on, the Notes) (“Note Register”) and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without prior notice to any Holder. The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

Section 2.04. Paying Agent to Hold Money in Trust.

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and shall notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent.

Section 2.07. Replacement Notes.

If any mutilated Note is surrendered to the Trustee, the Registrar or the Issuer and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing a Note.

Every replacement Note is a contractual obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08. Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receive proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

Section 2.09. Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer, or by any Subsidiary of the Issuer, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Trust Officer of the Trustee knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Issuer or any obligor upon the Notes or any Affiliate of the Issuer or of such other obligor.

Section 2.10. Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall, upon receipt of an Authentication Order, authenticate definitive Notes in exchange for temporary Notes. Holders of temporary Notes shall be entitled to all of the benefits accorded to Holders of Notes under this Indenture.

-65-

Section 2.11. Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of cancelled Notes in accordance with its standard procedures (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Notes shall be delivered to the Issuer, upon the Issuer’s written request. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12. Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12. The Trustee shall fix or cause to be fixed each such special record date and payment date; provided that no such special record date shall be less than ten (10) days prior to the related payment date for such defaulted interest. The Trustee shall promptly notify the Issuer of such special record date. At least fifteen (15) days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail or cause to be mailed, first-class postage prepaid, to each Holder a notice at his or her address as it appears in the Note Register that states the special record date, the related payment date and the amount of such interest to be paid.

Subject to the foregoing provisions of this Section 2.12 and for greater certainty, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 2.13. Consent Right; Right of First Refusal; Tag-Along Rights.

(a) Each Holder agrees that it shall not, without the prior written consent of Eligible Holders representing a majority of the principal amount of Notes held by such Eligible Holders (which consent may be withheld in the sole and absolute discretion of the Eligible Holders), sell, assign or otherwise transfer or dispose of Notes (such sale, assignment or other transfer or disposition of any kind (other than a sale, assignment or other transfer or disposition of any kind to an Affiliate of such Holder), a “Transfer”) at any time prior to March 20, 2019. Each Holder, by accepting or purchasing any Notes, is deemed to acknowledge, and agree to be bound by, the provisions of this Section 2.13.

(b) In the event that any Holder (a “Transferor”) proposes to Transfer any of its Notes at any time on or after March 20, 2019, Eligible Holders shall have (i) a right to purchase all or any portion of such Holder’s Notes subject to such Transfer (a “Right of First Refusal”); or

-66-

(ii) the Tag-Along Rights as defined below; provided that in the event of a Transfer to the Issuer or any of its Subsidiaries (an “Issuer Transfer”), the foregoing shall not apply but the Issuer or such Subsidiary shall only be permitted to complete the Issuer Transfer if the Issuer or such Subsidiary repurchases Notes from any Eligible Holders that elect to have their Notes purchased on a pro rata basis in connection with the proposed Issuer Transfer at the same price such Notes are proposed to be purchased in the Issuer Transfer (which price, for the avoidance of doubt may be at below par and/or below the redemption price which may be applicable at such time). The Eligible Holders shall have the right to elect to Transfer Notes to the Proposed Transferee (as defined herein) on the same terms as the Transferor’s proposed Transfer in an amount equal to the aggregate principal amount of Notes the Proposed Transferee (as defined herein) actually proposes to purchase as set forth in the Transfer Notice (as defined herein) multiplied by a fraction, the numerator of which shall be the aggregate principal amount of Notes held by such Transferor and the denominator of which shall be the aggregate principal amount of Notes held by the Transferor and the Eligible Holders electing to exercise their Tag-Along Rights (the “Tag-Along Rights”) and such Transferor shall have the amount of its Offered Notes Transferred to such Proposed Transferee reduced by such amount.

(c) In the event of any proposed Transfer pursuant to clause (a) or (b) above, the Transferor shall deliver to the Eligible Holders (with a copy to the Trustee) a written notice (the “Transfer Notice”) stating: (i) the Transferor’s intention to Transfer such Notes (the “Offered Notes”); (ii) the name, address and phone number of each proposed purchaser or other transferee (the “Proposed Transferee”); (iii) the aggregate principal amount of Offered Notes to be Transferred to each Proposed Transferee; and (iv) the bona fide cash price for which the Transferor proposes to Transfer the Offered Notes (the “Offered Price”); and (v) a request that the Eligible Holders make an election, if any, to exercise their Right of First Refusal or Tag-Along Rights. Any Transfer Notice to the Eligible Holders shall be delivered to each of the Eligible Holders (with a copy to the Trustee) at their respective addresses set forth in Exhibit E hereto.

(d) Within ten (10) Business Days (the “Notice Period”) after the Eligible Holders receive a Transfer Notice, the Eligible Holders shall deliver to the Transferor (with a copy to the Trustee) a written notice (a “Confirmation Notice”) stating whether the Eligible Holders are electing to exercise their Right of First Refusal or Tag-Along Rights.

(e) If any Eligible Holders elect to exercise their Right of First Refusal, participating Eligible Holders shall be entitled to purchase, at the Offered Price, their pro rata share of Offered Notes based on the aggregate principal amount of Notes held by each Eligible Holder as of the Issue Date. Payment of the purchase price for the Offered Notes purchased by an Eligible Holder exercising its Right of First Refusal shall be made directly to the Transferor within five (5) Business Days after the end of the Notice Period.

(f) If any Eligible Holders elect to exercise their Tag-Along Rights, participating Eligible Holders (“Tag-Along Holders”) shall be entitled to Transfer, at the Offered Price, their pro rata share of Offered Notes in accordance with clause (b) above. To the extent that any Proposed Transferee refuses to purchase Notes from a Tag-Along Holder exercising its Tag-Along Rights hereunder, such Transferor shall not Transfer to such Proposed Transferee any Notes unless and until, simultaneously with such Transfer, such Proposed Transferee shall purchase such Notes from such a Tag-Along Holder on the same terms and conditions specified in the Transfer Notice.

-67-

(g) If the Eligible Holders decline to exercise their Right of First Refusal with respect to all or any portion of the Offered Notes (the “Unexercised Notes”), then the Transferor shall be permitted to Transfer such Unexercised Notes to the Proposed Transferee, subject to any Tag-Along Rights, at the Offered Price provided that such Transfer (i) is consummated within five (5) Business Days after the end of the Refusal Period; (ii) is on terms no more favorable than the terms proposed in the Transfer Notice; and (iii) is otherwise completed in accordance with Section 2.06 hereof. If the Offered Notes are not so Transferred during such five (5) Business Day period, then the Transferor may not Transfer any of such Offered Notes without complying again in full with the provisions of this Indenture.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than sixty (60) days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased.

No Notes of $2,000 or less can be redeemed in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased (or if a PIK Note Payment has been made, the Notes may be redeemed in minimum denominations of $1.00 and any integral multiple in excess thereof). Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

-68-

Section 3.03. Notice of Redemption.

Subject to Section 3.09 hereof, the Issuer shall deliver electronically or mail or cause to be mailed by first-class mail, postage prepaid, notices of redemption at least thirty (30) days but not more than sixty (60) days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address (with a copy to the Trustee), except that redemption notices may be mailed more than sixty (60) days prior to a redemption date if the notice is issued in connection with Article 7 or Article 11 hereof. Except as set forth in Section 3.07 hereof, notices of redemption may not be conditional.

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

(a) the redemption date;

(b) the redemption price;

(c) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note representing the same indebtedness to the extent not redeemed shall be issued in the name of the Holder of the Notes upon cancellation of the original Note;

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

(h) if in connection with a redemption pursuant to Section 3.07 hereof, any condition to such redemption.

At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at its expense; provided that the Issuer shall have delivered to the Trustee, at least five (5) Business Days (or such shorter period as the Trustee may agree) before notice of redemption is required to be delivered or mailed to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04. Effect of Notice of Redemption.

Once notice of redemption is delivered or mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date, unless such redemption is conditioned on the happening of a future event at the redemption price. The notice, if delivered or mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05 hereof, on and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption.

-69-

Section 3.05. Deposit of Redemption or Purchase Price.

Prior to 11:00 a.m. (Eastern Time) on the redemption or purchase date, the Issuer shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest on all Notes to be redeemed or purchased on that date (including any PIK Notes).

If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest to the redemption or purchase date shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06. Notes Redeemed or Purchased in Part.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes 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.

Section 5.04. Waiver of Past Defaults.

Section 5.05. Control by Majority.

(a) Subject to Section 5.05(b), Holders of a majority in principal amount of the then total outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.

(b) Notwithstanding any other provision of this Indenture (including without limitation, Sections 5.02, 5.04, 5.05(a) and 8.02), without the express written consent of the Holders representing no less than 80% of the principal amount of the Notes, no Holder or Holders shall, and no Holder or Holders shall direct, instruct or provide notice to the Trustee to, and the Trustee shall not, directly or indirectly, take any action the result of which is to alter the validity, enforceability, meaning or effect of Section 4.26(b), including but not limited to: (i) amending or otherwise modifying any of Section 4.26(b), Section 5.01(c) or this Section 5.05(b); (ii) amending or otherwise modifying the definitions of any defined terms in this Indenture to the extent that such amendment or modification would, directly or indirectly, alter the validity, meaning, enforceability or effect of Section 4.26(b), including without limitation the defined term “Liquidity” and any defined terms included in such definitions; (iii) waiving any Default or Event of Default that has occurred or may occur as a result of the failure by the Issuer to comply with Section 4.26(b), whether prospectively or retroactively, including without limitation pursuant to Section 5.01(c); or (iv) rescinding any acceleration with respect to the Notes and its consequences, but only with respect to an Event of Default that occurred as a result of the failure by the Issuer to comply with Section 4.26(b), including without limitation pursuant to Section 5.01(c). Any action taken by any Holder or the Trustee, or any successor in interest of any of the foregoing, in breach of this Section 5.05(b) shall be deemed void ab initio and of no further effect.

-102-

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer or a Change of Control Offer), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 5.08. Collection Suit by Trustee.

If an Event of Default specified in Section 5.01(a) or (b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in their own names and as trustee of an express trust against the Issuer for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 5.09. Restoration of Rights and Remedies.

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

-103-

Section 5.10. Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11. Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 5.12. Trustee May File Proofs of Claim.

The Trustee is authorized to 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 (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes including the Guarantors), its creditors or its property and shall be entitled and empowered to participate as a member in any official committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such 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 to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.06 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 5.13. Priorities.

If the Trustee collects any money pursuant to this Article 5 or, after an Event of Default, any money or other property distributable in respect of the Issuer’s obligations under this Indenture, it shall pay out the money in the following order:

(i) to the Trustee (including any predecessor trustee), its agents and attorneys for amounts due under Section 6.06 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

-104-

(ii) to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and

(iii) to the Issuer or to such party as a court of competent jurisdiction shall direct, including a Guarantor, if applicable.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 5.13.

Section 5.14. 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 the Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 5.14 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

ARTICLE 6

TRUSTEE

Section 6.01. Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b) Except during the continuance of an Event of Default:

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

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

(c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(i) this paragraph does not limit the effect of paragraphs (b) or (g) of this Section 6.01;

-105-

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

(iii) 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 5.05 hereof.

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 6.01.

(g) No provision of this Indenture shall be deemed to impose any duty or obligation on the Trustee to perform any act or acts, receive or obtain any interest in property or exercise any interest in property, or exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Trustee shall be unqualified or incompetent in accordance with applicable law, to perform any such act or acts, to receive or obtain any such interest in property or to exercise any such right, power, duty or obligation; and no permissive or discretionary power or authority available to the Trustee shall be construed to be a duty.

Section 6.02. Rights of Trustee.

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or 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 resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(b) Before the Trustee acts, suffers or refrains from acting hereunder, it may require an Officers’ Certificate or an Opinion of Counsel or both and such matter may be deemed to be conclusively proved and established by such Officers’ Certificate, Opinion of Counsel or both. The Trustee shall not be liable for any action it takes, suffers or omits to take in good faith in

-106-

reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(c) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through attorneys or agents and the Trustee shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care.

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer shall be sufficient if signed by an Officer of the Issuer.

(f) None of the provisions of this Indenture shall require the Trustee to expend or risk its own funds or otherwise to incur any liability, financial or otherwise, 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 for believing that repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it.

(g) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of such Default or Event of Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Notes and this Indenture.

(h) In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(i) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in its capacity hereunder, and each agent, custodian and other Person employed to act hereunder (including, without limitation, as Collateral Trustee).

(j) The Trustee may request that the Issuer and any Guarantor deliver an Officers’ Certificate setting forth the names of the individuals and/or titles of Officers (with specimen signatures) authorized at such times to take specific actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person specified as so authorized in any certificate previously delivered and not superseded.

(k) The permissive right of the Trustee to take or refrain from taking action hereunder shall not be construed as a duty.

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

-107-

(m) The Issuer shall provide prompt written notice to the Trustee of any change to its fiscal year (it being expressly understood that the failure to provide such notice to the Trustee shall not be deemed a Default of Event of Default under this Indenture).

Section 6.03. Individual Rights of Trustee.

The Trustee in its individual or any other capacities may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not the Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within ninety (90) days. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.09 hereof.

Section 6.04. Trustee’s Disclaimer.

The Trustee shall not be responsible for and make no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 6.05. Notice of Defaults.

If a Default occurs and is continuing and if it is actually known to the Trustee, the Trustee shall deliver to Holders of Notes, as their names and addresses appear in the Note Register, a notice of the Default within ninety (90) days after it occurs or after it is known to the Trustee. Except in the case of a Default relating to the payment of principal, premium, if any, or interest on any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of the Holders. The Trustee shall not be deemed to know of any Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee at the Corporate Trust Office of the Trustee.

Section 6.06. Compensation and Indemnity.

The Issuer and the Guarantors, jointly and severally, shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree in writing from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer and the Guarantors, jointly and severally, shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee and their officers, agents, directors and employees for, and hold the Trustee harmless against, any and all loss, damage, claim, liability or expense (including attorneys’ fees), including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it in connection with the acceptance or administration of this trust or trusts hereunder and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture against the Issuer or any of the Guarantors (including this Section 6.06) or defending itself against any claim whether asserted by any Holder, the

-108-

Issuer, any Guarantor or any other Person, or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder). The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend the claim and the Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence as determined by a court of competent jurisdiction in a final and non-appealable decision.

The obligations of the Issuer under this Section 6.06 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

To secure the performance of the obligations of the Issuer and the Guarantors in this Section 6.06, the Trustee shall have a Lien prior to the Notes upon the Collateral and all money or property held or collected by the Trustee, except funds held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture, the termination for any reason of this Indenture, and the resignation or removal of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.01(f) or (g) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Section 6.07. Replacement of Trustee.

A resignation or removal of the Trustee and appointment of successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 6.07. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(a) the Trustee fails to comply with Section 6.09 hereof;

(b) the Trustee is adjudged bankrupt or insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall promptly appoint a successor Trustee. Within one year after a successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

If a successor Trustee does not take office within sixty (60) days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Issuer’s expense), the Issuer or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

-109-

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 6.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 6.07, the Issuer’s obligations under Section 6.06 hereof shall continue for the benefit of the retiring Trustee.

Section 6.08. Successor Trustee by Merger, Etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act shall be the successor Trustee. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

Section 6.09. Eligibility; Disqualification.

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.

ARTICLE 7

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 7.01. Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuer may, at its option and at any time, elect to have either Section 7.02 or 7.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 7.

Section 7.02. Legal Defeasance and Discharge.

Upon the Issuer’s exercise under Section 7.01 hereof of the option applicable to this Section 7.02, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 7.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Guarantees thereof on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 7.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the

-110-

Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of Notes to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 7.04 hereof;

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

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

(d) this Section 7.02.

Subject to compliance with this Article 7, the Issuer may exercise its option under this Section 7.02 notwithstanding the prior exercise of its option under Section 7.03 hereof.

Section 7.03. Covenant Defeasance.

Upon the Issuer’s exercise under Section 7.01 hereof of the option applicable to this Section 7.03, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 7.04 hereof, be released from their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 4.21, 4.22, 4.23, 4.24, 4.25 and 4.26, hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 7.04 hereof are satisfied (“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 5.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 7.01 hereof of the option applicable to this Section 7.03, subject to the satisfaction of the conditions set forth in Section 7.04 hereof, Sections 5.01(e), 5.01(f) (solely with respect to Restricted Subsidiaries), 5.01(g) (solely with respect to Restricted Subsidiaries), 5.01(h), 5.01(i), 5.01(j), 5.01(k), 5.01(l), 5.01(m) hereof shall not constitute Events of Default.

Section 7.04. Conditions to Legal or Covenant Defeasance.

The following shall be the conditions to the application of either Section 7.02 or 7.03 hereof to the outstanding Notes:

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the Notes:

-111-

any investigation, without consideration of any reinvestment or interest to pay the principal of, premium, if any, and interest due (including an amount of cash sufficient to pay all PIK Interest) on the Notes on the stated maturity date or on the redemption date, as the case may be, of such principal, premium, if any, or interest on such Notes and the Issuer must specify whether such Notes are being defeased to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel from counsel who is reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions,

(a) the Issuer has received from, or there has been published by, the United States Internal Revenue Service a ruling, or

(b) since the issuance of the Notes, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, subject to customary assumptions and exclusions, the Holders shall not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and shall be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel from counsel who is reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders shall not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and shall be subject to such U.S. tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness, and, in each case the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any Credit Facility or any other material agreement or instrument (other than this Indenture) to which, the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith);

(6) the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date of such opinion and subject to customary assumptions and exclusions following the deposit, the trust funds shall not be subject to the effect of Section 547 of Title 11 of the Code;

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or any Guarantor or others; and

Section 7.05. Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 7.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 7.05, the “Trustee”) pursuant to Section 7.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 7.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article 7 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the request of the Issuer any money or Government Securities held by it as provided in Section 7.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 7.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 7.06. Repayment to Issuer.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium or interest on any Note and remaining unclaimed for two years after such principal, and premium or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease.

Section 7.07. Reinstatement.

If the Trustee or Paying Agent is unable to apply any Dollars or Government Securities in accordance with Section 7.02 or 7.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuer’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 7.02 or 7.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 7.02 or 7.03 hereof, as the case may be; provided that, if the Issuer makes any payment of principal of, premium or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Notwithstanding Section 8.02 hereof, the Issuer, any Guarantor (with respect to a Guarantee or this Indenture), the Trustee and the Collateral Trustee may amend or supplement this Indenture, any Security Instruments, the Notes and any Guarantee thereof without the consent of any Holder:

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

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

(3) to provide the assumption of the Issuer’s or any Guarantor’s obligations to the Holders and to the Trustee;

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under this Indenture of any such Holder;

(5) to add covenants for the benefit of the Holders or to surrender any right or power conferred upon the Issuer or any Guarantor;

(6) to evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee thereunder pursuant to the requirements thereof;

(9) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of such Notes; provided, however, that (i) compliance with this Indenture as so amended would not result in such Notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer Notes;

(10) to add additional assets as Collateral;

(11) to release Collateral from the Lien or any Guarantor from its Guarantee, in each case pursuant to this Indenture and the Security Instruments when permitted or required by this Indenture, the Guarantees, or the Security Instruments; or

Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 6.02 hereof, the Trustee shall join with the Issuer and the Guarantors in

-114-

the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Notwithstanding the foregoing, no Opinion of Counsel shall be required in connection with the addition of a Guarantor under this Indenture upon execution and delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, and delivery of an Officers’ Certificate.

After an amendment, supplement or waiver under this Section 8.01 becomes effective, the Issuer shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 8.02. With Consent of Holders of Notes.

Except as provided below in this Section 8.02, the Issuer, subject to Section 5.05(b), the Trustee and the Collateral Trustee may amend or supplement this Indenture, any Security Instruments, the Notes and any Guarantee thereof with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 5.04 and 5.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes or any Guarantees thereof may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 and Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 8.02.

Notwithstanding the foregoing, with respect to any provision in this Indenture, the Notes and any Guarantee thereof that requires the consent of the Eligible Holders or Lead Holders, as applicable, representing a majority of the principal amount of Notes held by such Eligible Holders or Lead Holders, as applicable, the Issuer, the Trustee and the Collateral Agent will notify all Eligible Holders or Lead Holders, as applicable, in advance of any applicable amendment or supplement taking effect and may not amend or supplement such provision without the consent of the Eligible Holders or Lead Holders, as applicable, representing a majority of the principal amount of Notes held by such Eligible Holders or Lead Holders, as applicable.

Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 6.02 hereof, the Trustee shall join with the Issuer in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

It shall not be necessary for the consent of the Holders of Notes under this Section 8.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

-115-

After an amendment, supplement or waiver under this Section 8.02 becomes effective, the Issuer shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

Without the consent of each affected Holder of Notes, an amendment or waiver under this Section 8.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of such Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the fixed final maturity of any such Note or alter or waive the provisions with respect to the redemption of such Notes (other than provisions relating to Section 3.09, Section 4.10 and Section 4.14 hereof to the extent that any such amendment or waiver does not have the effect of reducing the principal of or changing the fixed final maturity of any such Note or altering or waiving the provisions with respect to the redemption of such Notes);

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

(4) waive a Default in the payment of principal of or premium, if any, or interest on the Notes, except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of such Notes and a waiver of the payment default that resulted from such acceleration, or in respect of a covenant or provision contained in this Indenture or any Guarantee thereof which cannot be amended or modified without the consent of all Holders of Notes;

(5) make any Note payable in money other than that stated therein;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments of principal of or premium, if any, or interest on the Notes;

(7) make any change in these amendment and waiver provisions;

(8) impair the right of any Holder of Notes to receive payment of principal of, or interest on, such Holder’s Notes 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 Notes;

(9) make any change to or modify the ranking of the Notes that would adversely affect the Holders of such Notes; or

(10) except as expressly permitted by this Indenture, modify the Guarantees of the Notes by any Significant Subsidiary in any manner adverse in any material respect to the Holders.

In addition, without the consent of the Holders of at least 66²⁄₃% in aggregate principal amount of Notes then outstanding, no amendment, supplement or waiver may modify any Security Instruments or the provisions in this Indenture dealing with the Collateral or the Security Instruments that would have the impact of releasing all or substantially all of the Collateral from the Liens of the Security Instruments (except as permitted by the terms of this Indenture and the Security Instruments) or change or alter the priority of the security interests in the Collateral. Without the consent of the Holders of at least a majority

-116-

in aggregate principal amount of Notes then outstanding, no amendment, supplement or waiver may (1) modify any Security Instrument or the provisions in this Indenture dealing with the Collateral or the Security Instruments that would have the impact of releasing less than all or substantially all of the Collateral from the Liens of the Security Instruments (except as permitted by the terms of this Indenture and the Security Instruments), (2) make any change in any Security Instrument or the provisions in this Indenture dealing with the application of trust proceeds of the Collateral that would adversely affect the Holders in any material respect or (3) modify the Intercreditor Agreement in any manner adverse to the Holders in any material respect other than in accordance with the terms of this Indenture and the Security Instruments.

Section 8.03. Effect of Supplemental Indentures; Revocation and Effect of Consents.

Upon the execution of any supplemental indenture under this Article 8, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, 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 unless the consent of the requisite number of Holders has been obtained.

Section 8.04. Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

Section 8.05. Trustee to Sign Amendments, Etc.

The Trustee and Collateral Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 8 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee and Collateral Trustee. The Issuer may not sign an amendment, supplement or waiver until the Board of Directors approves it. In executing any amendment, supplement or waiver, the Trustee and Collateral Trustee shall be entitled to receive and (subject to Section 6.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.02 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or

-117-

supplemental indenture is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof. Notwithstanding the foregoing, no Opinion of Counsel shall be required for the Trustee and Collateral Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture.

ARTICLE 9

GUARANTEES

Section 9.01. Guarantee.

Subject to this Article 9, each of the Guarantors hereby, jointly and severally, irrevocably and unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: (a) the principal of, interest, premium on the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 9.01.

If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 5 hereof for the purposes of this Guarantee, notwithstanding any stay,

-118-

injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 5 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantees.

Each Guarantee shall remain in full force and effect and continue to be effective in any insolvency proceeding affecting the Issuer, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Guarantees thereof, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Each payment to be made by a Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

Section 9.02. Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as shall, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 9, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all guaranteed obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

Section 9.03. Execution and Delivery.

To evidence its Guarantee set forth in Section 9.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by its President, one of its Vice Presidents or one of its Assistant Vice Presidents.

Each Guarantor hereby agrees that its Guarantee set forth in Section 9.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

-119-

If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Guarantee shall be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

If required by Section 4.15 hereof, the Issuer shall cause any newly created or acquired Restricted Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 9, to the extent applicable.

Section 9.04. Subrogation.

Each Guarantor shall be subrogated to all rights of Holders against the Issuer in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 9.01 hereof; provided that, if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuer under this Indenture or the Notes shall have been paid in full.

Section 9.05. Benefits Acknowledged.

Each Guarantor acknowledges that it shall receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Guarantee are knowingly made in contemplation of such benefits.

Section 9.06. Release of Guarantees.

A Guarantee of the Notes by a Guarantor shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Issuer or the Trustee is required for the release of such Guarantor’s Guarantee, upon:

(1) (A) any sale, exchange or transfer (by merger, consolidation, amalgamation, wind-up liquidation, dissolution or otherwise) of the Capital Stock of such Guarantor (including any sale, exchange or transfer), after which the applicable Guarantor is no longer a Restricted Subsidiary, if such sale, exchange or transfer is made in compliance with the applicable provisions of this Indenture;

(B) the release or discharge of the guarantee by, or direct obligation of, such Guarantor of its guarantee obligations in respect of all Series of Secured Debt (other than the Notes), Senior Debt or the guarantee which resulted in the creation of such Guarantee, except a discharge or release by or as a result of payment under such guarantee or direct obligation (it being understood that a release subsequent to a contingent reinstatement is still a release) or a full and complete discharge of all Series of Secured Debt (other than the Notes);

(C) the proper designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in compliance with this Indenture; or

(D) the Issuer exercising its Legal Defeasance option or Covenant Defeasance option in accordance with Article 7 hereof or the Issuer’s obligations under this Indenture being discharged in accordance with the terms of this Indenture;

-120-

(E) the merger or consolidation of any Guarantor with and into the Issuer or another Guarantor that is the surviving Person in such merger or consolidation, or upon the liquidation of such Guarantor following the transfer of all or substantially all of its assets to the Issuer or another Guarantor; and

(2) such Guarantor delivering to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in this Indenture relating to such transaction have been complied with.

ARTICLE 10

COLLATERAL AND SECURITY

Section 10.01. The Collateral Trustee.

By accepting a Note, each Holder is deemed to have irrevocably appointed the Collateral Trustee to act as its agent under the Security Instruments and the Intercreditor Agreement and irrevocably authorized the Collateral Trustee to (i) perform the duties and exercise the rights, powers and discretions that are specifically given to it under the Security Instruments, the Intercreditor Agreement or other documents to which it is a party, together with any other incidental rights, powers and discretions, and (ii) execute each document expressed to be executed by the Collateral Trustee on its behalf. Each Holder agrees that the Collateral Trustee shall be entitled to the rights, privileges, protections, immunities, indemnities and benefits provided to the Trustee by this Indenture, the Intercreditor Agreement and the Security Instruments. The Collateral Trustee will have no duties or obligations except those expressly set forth in the Security Instruments to which it is party or in the Intercreditor Agreement; provided, however that no provision of this Indenture shall be construed to relieve the Collateral Trustee from liability for its own grossly negligent action, its own grossly negligent failure to act or its own willful misconduct as determined by a court of competent jurisdiction in a final and non-appealable decision. Notwithstanding the generality of the foregoing:

(a) The duties and obligations of the Collateral Trustee shall be determined solely by the express provisions of this Indenture, the Intercreditor Agreement and the Security Instruments and the Collateral Trustee shall not be liable to any party hereto, to the Intercreditor Agreement or to any Security Instrument to which it is a party by reason of any failure on the part of any other party hereto or any maker, guarantor, endorser or other signatory of any document or any other Person to perform such Person’s obligations under any such document.

(b) The Collateral Trustee shall not be responsible in any manner for the validity, enforceability or sufficiency of this Indenture, the Security Instruments, the Intercreditor Agreement or any Collateral delivered under the Security Instruments, or for the value or collectability of any Notes or for any representations made or obligations assumed by any party other than the Collateral Trustee. The Collateral Trustee shall not be bound to examine or inquire into or be liable for any defect or failure in the right or title of the Issuer or the Guarantors to all or any of the assets whether such defect or failure was known to the Collateral Trustee or might have been discovered upon examination or inquiry and whether capable of remedy or not.

(c) The Collateral Trustee shall not be responsible for any unsuitability, inadequacy, expiration or unfitness of any security interest created pursuant to any Security Instrument pertaining to this matter nor shall it be obligated to make any investigation into, and shall be entitled to assume, the adequacy and fitness of any security interest created pursuant to any Security Instrument pertaining to this matter.

-121-

(d) The Collateral Trustee shall not be liable for any error of judgment, or for any act done or step taken or omitted by it in good faith or for any mistake in fact or law, or for anything which it may do or refrain from doing in connection herewith, in each case except for its own gross negligence or willful misconduct.

(e) The Collateral Trustee may seek the advice, at the expense of the Issuer, of legal counsel in the event of any dispute or question as to the construction of any of the provisions of this Indenture, the Intercreditor Agreement or its duties hereunder or under any Security Instrument or applicable law, and it shall incur no liability and shall be fully protected in respect of any action taken, omitted or suffered by it in good faith in accordance with the advice or written opinion of such counsel.

(f) The Collateral Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, approval or other paper or document it receives in connection with this Indenture, the Intercreditor Agreement or any Security Instrument.

(g) In no event shall the Collateral Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Collateral Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(h) In no event shall the Collateral Trustee be liable for any failure or delay in the performance of its obligations hereunder, under the Intercreditor Agreement or under any Security Instrument because of circumstances beyond its control, including, but not limited to, acts of God, flood, war (whether declared or undeclared), terrorism, strikes, work stoppages, civil or military disturbances, nuclear or natural catastrophes, fire, riot, embargo, loss or malfunctions of utilities, communications or computer (software and hardware) services, government action, including any laws, ordinances, regulations, governmental action or the like which delay, restrict or prohibit the providing of the services contemplated by this Indenture, the Intercreditor Agreement or any Security Instrument.

(i) The Collateral Trustee agrees to accept and act upon facsimile or electronic transmission of written instructions pursuant to this Indenture or any Security Instrument; provided, however that (i) the party providing such written instructions, subsequent to such transmission of written instructions, shall provide the originally executed instructions or directions to the Collateral Trustee in a timely manner, and (ii) such originally executed instructions or directions shall be signed by an authorized representative of the party providing such instructions or directions.

(j) The Collateral Trustee shall be entitled to seek written directions from the requisite Holders or the Trustee (at the direction of the requisite Holders) prior to taking any action under this Indenture, the Intercreditor Agreement or any Security Instrument or with respect to any Collateral.

(k) The Collateral Trustee shall not be responsible to any Holder for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any Lien or security interest created or purported to be created under or in connection with, any Security Instrument or any other instrument or document furnished pursuant thereto.

-122-

(l) The Collateral Trustee shall have no responsibility for or liability with respect to monitoring compliance of any other party to the Security Instruments, the Intercreditor Agreement, this Indenture or any other document related hereto or thereto. The Collateral Trustee has no duty to monitor the value or rating of any Collateral on an ongoing basis.

(m) No provision of this Indenture, the Intercreditor Agreement or any Security Instrument shall require the Collateral Trustee to expend, advance or risk its own funds or otherwise incur any financial liability in the performance of any of its duties under this Indenture, the Intercreditor Agreement or in any of the Security Instruments or in the exercise of any of its rights or powers hereunder, under the Intercreditor Agreement or under any of the Security Instruments unless it is indemnified to its satisfaction and the Collateral Trustee shall have no liability to any Person for any loss occasioned by any delay in taking or failure to take any such action while it is awaiting an indemnity satisfactory to it.

(n) Whenever in the administration of this Indenture, the Intercreditor Agreement or any Security Instrument the Collateral Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Collateral Trustee (unless other evidence be herein specifically prescribed) may conclusively rely upon written instructions from the requisite Holders.

(o) The Collateral Trustee may act and rely and shall be protected in acting and relying in good faith on the opinion or advice of, or information obtained from, any counsel, accountant, investment banker, appraiser or other expert or adviser, whether retained or employed by the Holders or by the Collateral Trustee.

(p) The Collateral Trustee may employ or retain such counsel, accountants, sub-agent, agent or attorney in fact, appraisers or other experts or advisers as it may reasonably require for the purpose of determining and discharging its rights and duties hereunder and shall not be responsible for the actions of any such parties it appoints with due care.

(q) The Collateral Trustee may request that the requisite Holders or other parties deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, the Intercreditor Agreement or any Security Instrument.

(r) Money held by the Collateral Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Collateral Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed by the Collateral Trustee in writing.

(s) Notwithstanding anything to the contrary herein, beyond the exercise of reasonable care in the custody thereof, the Collateral Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. Without limiting the generality of the foregoing, the Collateral Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Lien or security interest in the Collateral. The Collateral Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords similar collateral and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee.

-123-

(t) The Collateral Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens on any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Trustee shall have no duty to ascertain or inquire as to or monitor the performance or observance of any of the terms of this Indenture or the Security Instruments.

(u) The Issuer and the Guarantors, jointly and severally, shall defend, indemnify, and hold harmless the Collateral Trustee from and against any claims, demands, penalties, fines, liabilities, settlements, damages or reasonable costs or expenses of whatever kind or nature, known or unknown, contingent or otherwise, arising out of the following in respect of the Collateral: (w) the presence, disposal, release, or threatened release of any Hazardous Materials which are on, from, or affecting the soil, water, vegetation, buildings, personal property, Persons or animals; (x) any personal injury (including wrongful death) or property damage (real or personal) arising out of or related to such Hazardous Materials; (y) any lawsuit brought or threatened, settlement reached, or government order relating to such Hazardous Materials, and/or (z) any violation of laws, orders, regulations, requirements or demands of government authorities, which are based upon or in any way related to such Hazardous Materials including, reasonable attorney and consultant fees and expenses, reasonable investigation and laboratory fees, court costs, and reasonable litigation expenses, except, in each case, where such claims, demands, penalties, fines, liabilities, settlements, damages, costs or expenses arise from the gross negligence or willful misconduct of the Collateral Trustee as determined in a final, non-appealable order of a court of competent jurisdiction.

(v) The Collateral Trustee reserves the right to conduct an environmental audit prior to foreclosing on any real estate Collateral or mortgage Collateral. The Collateral Trustee reserves the right to forebear from foreclosing in its own name if to do so may expose it to undue risk.

(w) Upon any payment or distribution of assets hereunder, under the Intercreditor Agreement or under any Security Instrument, the Collateral Trustee shall be entitled to conclusively rely upon any order or decree entered by any court of competent jurisdiction in which an insolvency or liquidation proceeding is pending, or a certificate of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit of creditors, agent or other Person making such payment or distribution in such insolvency or liquidation proceeding, delivered to the Collateral Trustee, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto.

(d) Each Holder, by accepting a Note, consents and agrees to the terms of the Security Instruments entered into on the Issue Date or from time to time thereafter (including the provisions providing for the possession, use, release and foreclosure of Collateral) as each may be amended from time to time in accordance with their terms and this Indenture, the Security Instruments and the Intercreditor Agreement, and authorizes and directs the Trustee and the Collateral Trustee to execute and deliver the Security Instruments, as applicable, and any documents relating thereto, in each case on behalf of such Holder and without any further consent.

(e) In the event that security interests in any of the Collateral are not created as of the Issue Date, the Issuer and the Guarantors shall use commercially reasonable efforts to implement security arrangements with respect to such Collateral as promptly as reasonably practicable after the Issue Date (or on such later date as may be permitted by the Holders in their sole discretion).

(f) Each Holder, by accepting the Notes, is deemed to acknowledge that, as more fully set forth in the Security Instruments, the Collateral as now or hereafter constituted shall be for the benefit of all the Holders, the Collateral Trustee, the Trustee and the other secured parties described in the Security Instruments and that the Lien granted in the Security Instruments relating to the Notes in respect of the Trustee, the Collateral Trustee, the Holders and such other secured parties is subject to and qualified and limited in all respects by the Security Instruments and actions that may be taken thereunder.

Section 10.04. Intercreditor Agreement. By accepting a Note, each Holder is deemed to acknowledge that the obligations of the Issuer under the Senior Priority Lien Debt, the Junior Priority Lien Debt, the Junior Lien Debt and any Refinancing Indebtedness in respect thereof are and shall be secured by Liens on assets of the Issuer and the Guarantors that constitute Collateral under the Security Instruments and that the relative Lien priorities and other creditor rights of the Holders hereunder and the secured parties thereunder will be set forth in the Intercreditor Agreement. By accepting a Note, each Holder is deemed to acknowledge that it has received a copy of the Intercreditor Agreement. By accepting a Note, each Holder is deemed to (a) consent to the subordination of the Liens on the Collateral securing the Notes and the Guarantees thereof on the terms set forth in the Intercreditor Agreement, authorize and direct the Trustee and the Collateral Trustee to execute and deliver the Intercreditor Agreement and any documents relating thereto, in each case on behalf of such Holder and without any further consent, authorization or other action by such Holder, (c) agrees that, upon the execution and delivery thereof, such Holder will be bound by the provisions of the Intercreditor Agreement as if it were a signatory thereto and will take no actions contrary to the provisions of the Intercreditor Agreement and (d) agrees that no Holder shall have any right of action whatsoever against the Trustee or the Collateral Trustee as a result of any action taken by the Trustee or the Collateral Trustee pursuant to this Section 10.04 or in accordance with the terms of the Intercreditor Agreement. By accepting a Note, each Holder is deemed to further irrevocably authorize and direct the Collateral Trustee (i) to take such actions as shall

-126-

be required to release Liens on the Collateral in accordance with the terms of the Intercreditor Agreement and (ii) to enter into such amendments, supplements or other modifications to the Intercreditor Agreement in connection with any extension, renewal, refinancing or replacement of any Notes or any Refinancing Indebtedness in respect thereof as are reasonably acceptable to the Collateral Trustee to give effect thereto, in each case on behalf of such Holder and without any further consent, authorization or other action by such Holder. The Collateral Trustee shall have the benefit of the provisions of Article 6 with respect to all actions taken by it pursuant to this Section 10.04 or in accordance with the terms of the Intercreditor Agreement to the full extent thereof.

Section 10.05. Further Assurances.

The Issuer and the Guarantors shall, at their sole expense, take all actions that are required to confirm that the Collateral Trustee holds, for the benefit of the Secured Parties and the holders of any Priority Lien Obligations, duly created, enforceable and perfected Priority Liens upon the Collateral and security interests in the Collateral (subject to the Intercreditor Agreement and Permitted Prior Liens) as contemplated by this Indenture, the Notes, the Guarantees of the Notes and the Security Instruments.

Subject to the applicable limitations set forth in the Security Instruments, the Intercreditor Agreement and herein, the Issuer and the Guarantors shall, at their sole expense, execute, acknowledge and deliver such documents and instruments and take such other actions, as may be required by applicable law or the applicable Security Instruments to create, protect, assure, perfect, transfer and confirm the Liens, benefits, property and rights conveyed or intended to be conveyed by this Indenture or the Security Instruments for the benefit of the Secured Parties in the Collateral, including any acquired Property pursuant to Section 4.24.

Notwithstanding anything to the contrary contained in this Indenture, the Intercreditor Agreement or any Security Instrument, neither the Collateral Trustee nor any Holder shall be required to execute any agreement, document or instrument creating or evidencing the subordination of the Liens on the Collateral securing the Notes and the Guarantees thereof to any Permitted Prior Liens.

ARTICLE 11

SATISFACTION AND DISCHARGE

Section 11.01. Satisfaction and Discharge.

This Indenture shall be discharged and shall cease to be of further effect as to all Notes, when either:

(1) all Notes theretofore authenticated and delivered, except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust, have been delivered to the Trustee for cancellation; or

(2) (A) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise, shall become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, Government Securities of the United States of America, or a combination thereof, in such amounts as shall be sufficient, in the opinion of a nationally recognized firm of independent public accountants without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(B) no Default (other than that resulting from borrowing funds to be applied to make such deposit or the grant of any Lien securing such borrowing or any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) with respect to this Indenture or the Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit shall not result in a breach or violation of, or constitute a default under, any Credit Facility or any other material agreement or instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any

-128-

Guarantor is bound (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith);

(1) the Issuer has paid or caused to be paid all sums payable by it under this Indenture; and

(2) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be.

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

Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to Section 11.01(2)(A), the provisions of Section 11.02 and Section 7.06 hereof shall survive.

Section 11.02. Application of Trust Money.

Subject to the provisions of Section 7.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent are unable to apply any money or Government Securities in accordance with Section 11.01 hereof 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 Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium or interest on any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.
