The Issuer has duly authorized the creation of an issue of 7.125% Senior Secured Notes due 2017 (the “Initial Notes”) and, to provide therefor, the Issuer and each Guarantor have duly authorized the execution and delivery of this Indenture.

(a) Consolidated Income Tax Expense,

(b) Consolidated Amortization Expense (but only to the extent not included in Consolidated Interest Expense),

(c) Consolidated Depreciation Expense, and

(d) Consolidated Interest Expense,

in each case determined on a consolidated basis in accordance with GAAP, minus

(4) any gain (or loss), together with any related provisions for taxes on any such gain (or the tax effect of any such loss), realized during such period by the Issuer or any Restricted Subsidiary upon (i) any Asset Sale by the Issuer or any Restricted Subsidiary, and (ii) any extraordinary or nonrecurring gain (or extraordinary or nonrecurring loss), together with any related provision for taxes on any such extraordinary or nonrecurring gain (or the tax effect of any such extraordinary or nonrecurring loss) recorded or realized by the Issuer or any Restricted Subsidiary during such period.

For purposes of this definition of “Consolidated Cash Flow,” “nonrecurring” means any gain or loss as of any date that is not reasonably likely to recur within the two years following such date; provided that if there was a gain or loss similar to such gain or loss within the two years preceding such date, such gain or loss shall not be deemed nonrecurring.

For purposes of this definition, Consolidated Cash Flow and Consolidated Interest Expense shall be calculated after giving effect on a pro forma basis (including the pro forma effect of (x) any expense or cost reductions that have occurred or, in the reasonable judgment of the Issuer, are reasonably expected to occur and (y) the expected income, based on current market rates, from any Vessel Acquisition (regardless of whether these operating improvements, cost savings or expected income could then be reflected in pro forma financial statements prepared in accordance with Regulation S-X under the Securities Act or any other regulation or policy of the Commission related thereto)) for the period of such calculation to:

(1) the incurrence of any Indebtedness by or the issuance of any Preferred Stock of the Issuer or any Restricted Subsidiary (and the application of the proceeds thereof) and any repayment, repurchase, retirement, extinguishment or redemption of other Indebtedness or other Preferred Stock (and the application of the proceeds therefrom) (other than the incurrence or repayment of Indebtedness in the ordinary course of business for working capital purposes pursuant to any revolving credit arrangement) occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four-Quarter Period and on or prior to the Transaction Date, as if such incurrence, repayment, repurchase, issuance, retirement, extinguishment or redemption, as the case may be (and the application of the proceeds thereof), occurred on the first day of the Four-Quarter Period; and

(2) any Asset Sale, Vessel Acquisition or Asset Acquisition (including, without limitation, any Vessel Acquisition or Asset Acquisition giving rise to the need to make such calculation as a result of the Issuer or any Restricted Subsidiary (including any Person who becomes a Restricted Subsidiary as a result of such Asset Acquisition) incurring Acquired Indebtedness and also including any Consolidated Cash Flow attributable to such Vessel Acquisition or Asset Acquisition occurring during the Four-Quarter Period or at any time subsequent to the last day of the Four-Quarter Period and on or prior to the Transaction Date), as if such Asset Sale, Vessel Acquisition or Asset Acquisition (including the incurrence of, or assumption or liability for, any such Acquired Indebtedness) occurred on the first day of the Four-Quarter Period (and without regard to clause (2) of the definition of Consolidated Net Income).

ARTICLE 2

THE NOTES

Section 2.01. Form and Dating.

The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law or Depository rule or usage. The form of the Notes and any notation, legend or endorsement on them shall be satisfactory to both the Issuer and the Trustee. Each Note shall be dated the date of its issuance and shall show the date of its authentication.

The terms and provisions contained in the Notes, annexed hereto as Exhibit A, shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Issuer and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

The Notes shall be issued initially in the form of one or more permanent global Notes (the “Global Notes”). Notes offered and sold (i) in reliance on Rule 144A shall be issued initially in the form of one or more permanent Global Notes in registered form, substantially in the form set forth in Exhibit A (the “ Rule 144A Global Note”) and (ii) in offshore transactions in reliance on Regulation S shall be issued initially in the form of one or more permanent global Notes in registered form, substantially in the form set forth in Exhibit A (the “Regulation S Global Note”), and in each case shall be deposited with the Trustee, as custodian for the Depository, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. Notes transferred to Institutional Accredited Investors may be represented by a permanent Global Note in registered form, substantially in the form set forth in Exhibit A, and if so represented shall be deposited with the Trustee, as custodian for the Depository, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of any Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depository, as hereinafter provided.

Section 2.02. Execution and Authentication.

The Notes shall be executed on behalf of the Issuer by two Officers of the Issuer. Such signatures may be either manual or facsimile.

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

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

The Trustee or an authentication agent (the “Authenticating Agent”) shall authenticate (i) Initial Notes for original issue on the date of this Indenture in the aggregate principal amount not to exceed $300,000,000 and (ii) additional Notes (“Additional Notes”) for original issue following the date of this Indenture (so long as permitted by the terms of this Indenture, including, without limitation, Section 4.10 and Section 4.14 hereof). The written order shall specify the amount of Notes to be authenticated, the date on which the Notes are to be authenticated and shall further specify the amount of such Notes to be issued as a Global Note or Certificated Notes.

Notwithstanding the foregoing, all Notes issued under this Indenture shall vote and consent together on all matters (as to which any of such Notes may vote or consent) as one class and no series of Notes will have the right to vote or consent as a separate class on any matter.

-27-

The Trustee may appoint an Authenticating Agent to authenticate Notes. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. 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 Authenticating Agent. An Authenticating Agent has the same right as an Agent to deal with the Issuer and Affiliates of the Issuer.

The Notes shall be issuable only in registered form without coupons and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

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”), where Notes may be presented for payment (“Paying Agent”) and where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Registrar shall provide the Issuer a current copy of such register from time to time upon request of the Issuer. The Issuer may have one or more co-Registrars and one or more additional Paying Agents. Neither the Issuer nor any Affiliate of the Issuer may act as Paying Agent. The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to any Holder.

The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent.

The Issuer shall notify the Trustee of the name and address of any such Agent. If the Issuer fails to maintain a Registrar or Paying Agent, or agent for service of notices and demands, or fails to give the foregoing notice, the Trustee shall act as such. The Issuer initially appoints the Trustee as Registrar, Paying Agent and agent for service of notices and demands in connection with the Notes.

Section 2.04. Paying Agent to Hold Assets in Trust.

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all assets held by the Paying Agent for the payment of principal of or interest on Notes (whether such assets have been distributed to it by the Issuer or any other obligor on the Notes), and shall notify the Trustee in writing of any Default in making any such payment. The Issuer at any time may require a Paying Agent to distribute all assets held by it to the Trustee and account for any assets disbursed and the Trustee may at any time during the continuance of any Default in any payment due on the Notes, upon written request to a Paying Agent, require such Paying Agent to forthwith distribute to the Trustee all assets so held in trust by such Paying Agent together with a complete accounting of such sums. Upon distribution to the Trustee of all assets that shall have been delivered by the Issuer to the Paying Agent, the Paying Agent shall have no further liability for such assets.

Section 2.05. Noteholder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish or cause the Registrar to furnish to the Trustee on or before each March 15 and September 15 in each year, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders which list may be conclusively relied on by the Trustee.

Section 2.06. Transfer and Exchange.

Subject to the provisions of Sections 2.15 and 2.16 hereof, when Notes are presented to the Registrar or a co-Registrar with a request to register the transfer of such Notes or to exchange such Notes for an equal principal amount of Notes of other authorized denominations of the same series, the Registrar or co-Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Notes presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied

-28-

by a written instrument of transfer in form satisfactory to the Issuer and the Registrar or co-Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. To permit registrations of transfer and exchanges, the Issuer shall execute and the Trustee shall authenticate Notes at the Registrar’s or co-Registrar’s request. No service charge shall be made for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge in connection therewith payable by the transferor of such Notes (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Section 2.10, 3.06, 4.12, 4.15 or 8.05 hereof, in which event the Issuer shall be responsible for the payment of such taxes).

Without the prior consent of the Issuer, the Registrar or co-Registrar shall not be required to register the transfer of or exchange of any Note (i) during a period of 15 days before a selection of Notes to be redeemed, (ii) selected for redemption in whole or in part pursuant to Article 3 hereof, except the unredeemed portion of any Note being redeemed in part, or (iii) between a Record Date and the next succeeding Interest Payment Date.

Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Notes may be effected only through a book-entry system maintained by the Depository, and that ownership of a beneficial interest in the Note shall be required to be reflected in a book entry.

Section 2.07. Replacement Notes.

If a mutilated Note is surrendered to the Trustee or if the Holder presents evidence to the satisfaction of the Issuer and the Trustee that the Note has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Note. An indemnity or a security bond may be required by the Issuer or the Trustee that is sufficient in the judgment of the Issuer and the Trustee to protect the Issuer, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. In every case of destruction, loss or theft, the applicant shall also furnish to the Issuer and to the Trustee evidence to their satisfaction of the destruction, loss or the theft of such Note and the ownership thereof. Each of the Issuer and the Trustee may charge for its expenses in replacing a Note. In the event any such mutilated, lost, destroyed or wrongfully taken Note has become due and payable, the Issuer in its discretion may pay such Note instead of issuing a new Note in replacement thereof. The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.

Every replacement Note is an additional obligation of the Issuer.

Section 2.08. Outstanding Notes.

Notes outstanding at any time are all Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, and those described in this Section 2.08 as not outstanding.

If a Note is replaced pursuant to Section 2.07 hereof (other than a mutilated Note surrendered for replacement), it ceases to be outstanding until the Issuer and the Trustee receive proof satisfactory to each of them that the replaced Note is held by a protected purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07 hereof.

If by 10:00 a.m., New York City time, on a Redemption Date or the Maturity Date, the Paying Agent holds U.S. legal tender sufficient to pay all of the principal and interest due on the Notes payable on that date, then on and after that date such Notes cease to be outstanding and interest on them ceases to accrue.

Section 2.09. Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Issuer or any of its Affiliates shall be considered as though they are 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 which a Trust Officer of the Trustee actually knows are so owned shall be so considered. The Issuer shall notify the Trustee, in writing, when it or any of its Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired.

-29-

Section 2.10. Temporary Notes.

Until definitive Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Issuer in the form of an Officers’ Certificate. The Officers’ Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate upon receipt of a written order of the Issuer pursuant to Section 2.02 definitive Notes in exchange for temporary Notes.

Section 2.11. Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and the 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 and, at the written direction of the Issuer, dispose of and deliver evidence of such disposal of all Notes surrendered for registration of transfer, exchange, payment or cancellation in accordance with their then existing procedures therefor. Subject to Section 2.07 hereof, the Issuer may not issue new Notes to replace Notes that it has paid or delivered to the Trustee for cancellation. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. In no event shall the Trustee be required to destroy cancelled Notes.

Section 2.12. Defaulted Interest.

The Issuer shall pay interest on overdue principal (including post-petition interest in a proceeding under Bankruptcy Law) at the rate of interest then borne by the Notes. The Issuer shall, to the extent lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) at the rate of interest then borne by the Notes.

If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest to the Persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Issuer for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 15 days before the subsequent special record date, the Issuer shall mail to each Holder, as of a recent date selected by the Issuer, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid.

Notwithstanding the foregoing, any interest which is paid prior to the expiration of the 30-day period set forth in Section 6.01(a) hereof shall be paid to Holders as of the Record Date for the Interest Payment Date for which interest has not been paid.

Section 2.13. Deposit of Moneys.

No later than 10:00 a.m., New York City time, on each Interest Payment Date, Redemption Date, Change of Control Payment Date, Offer Payment Date and Maturity Date, the Issuer shall have deposited with the Paying Agent in immediately available funds U.S. legal tender sufficient to make payments, if any, due on such Interest Payment Date, Redemption Date, Change of Control Payment Date, Offer Payment Date or Maturity Date, as the case may be, in a timely manner which permits the Trustee to remit payment to the Holders on such Interest Payment Date, Redemption Date, Change of Control Payment Date, Offer Payment Date or Maturity Date, as the case may be. The principal and interest on Global Notes shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global Notes represented thereby. The principal and interest on Notes in certificated form shall be payable in the manner indicated in paragraph 2 of the Notes.

-30-

Section 2.14. CUSIP Number.

The Issuer in issuing the Notes may use “CUSIP,” “ISIN” or such other numbers, and if so, the Trustee shall use such CUSIP, ISIN or such other numbers in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or such other numbers printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee of any change in the CUSIP, ISIN or such other number.

Section 2.15. Book-Entry Provisions for Global Notes.

(a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in Section 2.17 hereof.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository or under the Global Note, and the Depository may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder.

(b) Subject to the rules and procedures of the Depository, Certificated Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in Global Notes only if (i) the Depository (x) notifies the Issuer that it is unwilling or unable to continue as Depository for any Global Note and the Issuer fails to appoint a successor Depository within 90 days of such notice or (y) has ceased to be a clearing company registered under the Exchange Act and a successor Depository is not appointed by the Issuer within 90 days after becoming aware of such cessation, (ii) the Issuer, at its option but subject to the procedures of the Depository, notifies the Trustee in writing that the Issuer elects to cause the issuance of Certificated Notes or (iii) an Event of Default has occurred and is continuing and the Depository notifies the Trustee of its desire to exchange Global Notes for Certificated Notes.

(c) In connection with the transfer of Global Notes as an entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute, and the Trustee shall, upon receipt of an authentication order from the Issuer in the form of an Officers’ Certificate, authenticate and deliver, to each beneficial owner identified by the Depository in writing in exchange for its beneficial interest in the Global Notes, an equal aggregate principal amount of Certificated Notes of authorized denominations.

(d) Any Certificated Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant to paragraph (b) or (c) shall, except as otherwise provided by Section 2.16 hereof, bear the Private Placement Legend.

(e) The Holder of any Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes.

Section 2.16. Registration of Transfers and Exchanges.

(a) Transfer and Exchange of Certificated Notes. When Certificated Notes are presented to the Registrar or co-Registrar with a request:

-31-

(i) to register the transfer of the Certificated Notes; or

then the Registrar or co-Registrar shall cancel such Certificated Note and cause, or direct the Depository to cause, in accordance with the standing instructions and procedures existing between the Depository and the Registrar or co-Registrar, the principal amount of Notes represented by the applicable Global Note to be increased accordingly. If no Global Note representing Notes held by Qualified Institutional Buyers or Persons acquiring Notes in offshore transactions in reliance on Regulation S, as the case may be, is then outstanding, the Issuer shall issue and the Trustee shall, upon receipt of an authentication order of the Issuer executed by an Officer, authenticate such a Global Note in the appropriate principal amount.

(c) Transfer and Exchange of Global Notes. The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depository therefor.

If the applicable type of Global Note required to represent the interest to be transferred is not outstanding at the time of such request, the Issuer shall issue and the Trustee shall, upon receipt of an authentication order from the Issuer executed by an Officer, authenticate a new Global Note of such type in principal amount equal to the principal amount of the interest to be transferred.

(d) Transfer of a Beneficial Interest in a Global Note for a Certificated Note. (i) If Certificated Notes are to be issued in exchange for Global Notes pursuant to Section 2.15(b), then upon receipt by the Registrar or co-Registrar of written instructions, or such other form of instructions as is customary for the Depository, from the Depository or its nominee on behalf of any Person having a beneficial interest in a Global Note and upon receipt by the Trustee of a written order or such other form of instructions as is customary for the Depository or the Person designated by the Depository as having such a beneficial interest containing registration instructions and, in the case of any such transfer or exchange of a beneficial interest in Notes the offer and sale of which have not been registered under the Securities Act and which Notes are presented for transfer or exchange prior to the Resale Restriction Termination Date, the following additional information and documents:

then the Registrar or co-Registrar will cause, in accordance with the standing instructions and procedures existing between the Depository and the Registrar or co-Registrar, the aggregate principal amount of the applicable Global Note to be reduced and, following such reduction, the Issuer will execute and, upon receipt of an authentication order from the Issuer executed by an Officer, the Trustee will authenticate and deliver to the transferee a Certificated Note in the appropriate principal amount and series.

(ii) Certificated Notes issued in exchange for a beneficial interest in a Global Note pursuant to this Section 2.16(d) hereof shall be registered in such names and in such authorized denominations as the Depository, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Registrar or co-Registrar in writing.

(f) Private Placement Legend. Upon the transfer, exchange or replacement of Notes, the Registrar or co-Registrar shall deliver only Notes that bear the Private Placement Legend unless, and the Trustee is hereby authorized to deliver Notes without the Private Placement Legend if, (i) the Resale Restriction Termination Date shall have occurred or (ii) there is delivered to the Trustee an Opinion of Counsel reasonably satisfactory to the Issuer and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

REDEMPTION

Section 3.01. Notices to Trustee.

If the Issuer elects to redeem Notes pursuant to paragraph 5 of the Notes, at least 60 days prior to the Redemption Date or during such other period as the Trustee may agree to, the Issuer shall notify the Trustee in writing of the Redemption Date, the principal amount of Notes to be redeemed and the Redemption Price, if then determinable, and deliver to the Trustee an Officers’ Certificate stating that such redemption will comply with the conditions contained herein and in the Notes, as appropriate.

Section 3.02. Selection of Notes to be Redeemed.

In the event that less than all of the Notes are to be redeemed at any time, selection of the Notes to be redeemed shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed or, if such Notes are not then listed on a national security exchange, on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate; provided, however, that no Notes of a principal amount of $2,000 in original principal amount or less shall be redeemed in part; provided, further, that if a partial redemption is made with the proceeds of any Qualified Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depository), unless such method is otherwise prohibited. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon delivery of the original Note to the Paying Agent and cancellation of the original Note. On and after the Redemption Date, interest will cease to accrue on Notes or portions thereof called for redemption as long as the Issuer has deposited with the Paying Agents funds in U.S. legal tender in satisfaction of the applicable Redemption Price and amount of accrued interest, if any, payable pursuant to this Indenture.

Section 3.03. Notice of Redemption.

Notice of redemption shall be mailed by first class mail at least 30 but not more than 60 days before the Redemption Date to each Holder to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a satisfaction and discharge of this Indenture. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

The notice shall identify the Notes to be redeemed (including the CUSIP, ISIN or other number(s) thereof) and shall state:

(1) the Redemption Date;

(2) the Redemption Price (if then determinable and otherwise the method for its computation) and the amount of accrued interest, if any, to be paid;

(3) that, if any Note is being redeemed in part, the portion of the principal amount (equal to $2,000 in principal amount or any integral multiple of $1,000 in excess thereof) of such Note to be redeemed and that, on and after the Redemption Date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued;

(4) the name, address and telephone number of the Paying Agent;

(5) that Notes called for redemption must be surrendered to the Paying Agent at the address specified to collect the Redemption Price plus accrued interest, if any;

(7) the subparagraph of the Notes pursuant to which the Notes called for redemption are being redeemed; and

(8) if fewer than all the Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption.

Section 3.05. Deposit of Redemption Price.

If any Note called for redemption shall not be so paid, interest will continue to accrue and be paid, from the Redemption Date until such redemption payment is made, on the unpaid principal of the Note and any interest not paid on such unpaid principal, in each case, at the rate and in the manner provided for in Section 2.12 hereof.

(i) an Officers’ Certificate of such Foreign Successor Issuer stating that the obligation to pay the Additional Amounts or indemnification payments cannot be avoided by such Foreign Successor Issuer’s taking reasonable measures available to it; and

(ii) a written opinion of independent legal counsel to such Foreign Successor Issuer of recognized standing to the effect that such Foreign Successor Issuer has or will become obligated to pay such Additional Amounts or indemnification payments as a result of a change, amendment, official interpretation or application described above.

In addition, for purposes of determining any particular amount of Indebtedness under this covenant, guarantees, Liens or letter of credit obligations supporting Indebtedness otherwise included in the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness.

The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

Notwithstanding any other provision of this Section 4.10, in no event shall the reclassification of any lease or other liability as indebtedness due to a change in accounting principles after the Issue Date be deemed to be an incurrence of Indebtedness.

Section 4.12. Limitations on Asset Sales.

(a) The Issuer will not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary receives consideration at least equal to the Fair Market Value (such Fair Market Value to be determined at the time of contractually agreeing to such Asset Sale or, in circumstances where the Issuer or such Restricted Subsidiary grants a third party the right to purchase an asset, the date of such grant) of the assets included in such Asset Sale; and

(2)(a) at least 75% of the total consideration in such Asset Sale consists of cash or Cash Equivalents or (b) the Fair Market Value of all forms of consideration other than cash and Cash Equivalents received for all Asset Sales since the Issue Date does not exceed in the aggregate 10.0% of the Consolidated Tangible Assets of the Issuer at the time such determination is made.

For purposes of clause (2), the following shall be deemed to be cash:

(A) the amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness, Disqualified Equity Interests, or Indebtedness owed to an Affiliate of the Issuer) of the Issuer or such Restricted Subsidiary that is delivered to the Issuer or such Restricted Subsidiaries as consideration for such Asset Sale and promptly retired or extinguished without payment, or that is expressly assumed by the transferee of any such assets pursuant to (i) a written novation agreement that releases the Issuer or such Restricted Subsidiary from further liability therefor or (ii) an assignment agreement that includes, in lieu of such a release, the agreement of the transferee or its parent company to indemnify and hold harmless the Issuer or such Restricted Subsidiary from and against any loss, liability or cost in respect of such assumed liability,

(B) the amount of any obligations received from such transferee that are within 180 days after such Asset Sale converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash actually so received), and

(C) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests acquired in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or a Restricted Subsidiary or (iii) a combination of (i) and (ii).

(b) If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.12.

(c) Any Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Permitted Lien or exercise by the related lienholder of rights with respect thereto, including by deed or assignment in lieu of foreclosure, shall not be required to satisfy the conditions set forth in subclauses (1) and (2) of clause (a) of this Section 4.12.

(d) Notwithstanding the foregoing, the 75% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the provisions of Section 4.12(a) on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75% limitation.

-46-

(e) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary shall, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom to:

(i) if the Collateral Termination has occurred, prepay, repay, redeem, defease or purchase secured Indebtedness of the Issuer or a Restricted Subsidiary (other than Disqualified Equity Interests, Subordinated Indebtedness or Indebtedness owed to the Issuer or an Affiliate of the Issuer);

(ii) satisfy all mandatory repayment obligations under Credit Facilities arising by reason of such Asset Sale;

(iii) repay any Indebtedness which was secured by the assets sold in such Asset Sale; and/or

(iv)(A) make any capital expenditure or otherwise invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities) to be used by the Issuer or any Restricted Subsidiary in the Permitted Business, (B) acquire Qualified Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B).

(f) The amount of Net Available Proceeds not applied or invested as provided in the preceding clause (e) shall constitute “Excess Proceeds.”

(g) When the aggregate amount of Excess Proceeds equals or exceeds $30.0 million, the Issuer shall be required to make an offer to purchase from all Holders and, if applicable, purchase or redeem (or make an offer to do so) any Pari Passu Indebtedness of the Issuer the provisions of which require the Issuer to purchase or redeem such Indebtedness with the proceeds from any Asset Sales (or offer to do so), in an aggregate principal amount of Notes and such Pari Passu Indebtedness equal to the amount of such Excess Proceeds as follows:

(1) the Issuer will (a) make an offer to purchase (a “Net Proceeds Offer”) to all Holders in accordance with the procedures set forth in this Indenture, and (b) purchase or redeem (or make an offer to do so), pro rata in proportion to the respective principal amounts of the Notes and such other Indebtedness required to be purchased or redeemed, the maximum principal amount of Notes and Pari Passu Indebtedness that may be purchased or redeemed out of the amount (the “Payment Amount”) of such Excess Proceeds;

(2) the offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of the Notes tendered pursuant to a Net Proceeds Offer, plus accrued and unpaid interest thereon, if any, to the date such Net Proceeds Offer is consummated (the “Offered Price”), in accordance with the procedures set forth in this Indenture, and the purchase or redemption price for such Pari Passu Indebtedness (the “Pari Passu Indebtedness Price”) shall be as set forth in the related documentation governing such Indebtedness;

(3) if the aggregate Offered Price of Notes validly tendered and not withdrawn by Holders thereof exceeds the pro rata portion of the Payment Amount allocable to the Notes, Notes to be purchased will be selected on a pro rata basis; and

(4) upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

(h) To the extent that the sum of the aggregate Offered Price of Notes tendered pursuant to a Net Proceeds Offer and the aggregate Pari Passu Indebtedness Price paid to the holders of such Pari Passu Indebtedness is less than the Payment Amount relating thereto (such shortfall constituting a “Net Proceeds Deficiency”), the Issuer may use the Net Proceeds Deficiency, or a portion thereof, for any purposes not otherwise prohibited by the provisions of this Indenture.

-47-

(i) Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Issuer and its Restricted Subsidiaries, taken as a whole, will be governed by the provisions of Section 4.15 and/or the provisions of Article 5 and not by the provisions of this Section 4.12.

(j) Upon the commencement of a Net Proceeds Offer, the Issuer must send, by first-class mail, a notice to each Holder, with a copy to the Trustee, which notice shall govern the terms of such Offer. Such notice shall state:

(1) that such Offer is being made pursuant to this Section 4.12;

(2) the Offered Price and the Offer Payment Date;

(3) that any Note not tendered shall continue to accrue interest;

(4) that, unless the Issuer defaults in the payment of the Offered Price, any Notes accepted for payment pursuant to such Offer shall cease to accrue interest after the Offer Payment Date;

(5) that such Offer shall remain open for at least 20 Business Days or for such longer period as is required by law and that Holders accepting the offer to have their Notes purchased pursuant to such Offer shall be required to surrender the Notes, with the form entitled “Option of the Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Offer Payment Date;

(6) that Holders shall be entitled to withdraw their acceptance if the Paying Agent receives, not later than the close of business on the third Business Day preceding the Offer Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have such Notes purchased;

(7) that Holders whose Notes are being purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered;

(8) any other procedures that a Holder must follow to accept such Offer or effect withdrawal of such acceptance; and

(9) the name and address of the Paying Agent.

(k) The Issuer shall publicly announce the results of a Net Proceeds Offer as soon as practicable after the related Offer Payment Date.

(l) On the Offer Payment Date, the Issuer shall, to the extent lawful, (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Net Proceeds Offer, or such lesser amount thereof as the Issuer is required to purchase pursuant to this Section 4.12, (2) deposit with the Paying Agent an amount equal to the Offered Price in respect of all Notes or portions of Notes properly tendered and accepted for payment, and (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

(m) After the Issuer’s satisfaction of its obligations under the preceding clause (l), the Paying Agent shall as promptly as practicable mail to each Holder of Notes properly tendered the Offered Price for such Notes, and the Trustee shall as promptly as practicable authenticate and mail to each Holder a new Note in principal amount equal to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000.

-48-

The Issuer shall comply with applicable tender offer rules, including the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.12, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.12 by virtue of this compliance.

Section 4.13. Limitations on Transactions with Affiliates.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, in one transaction or a series of related transactions involving aggregate payments or consideration in excess of $1.0 million, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “Affiliate Transaction”), unless:

(1) such Affiliate Transaction is on terms that are not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that could reasonably be expected to have been obtained in a comparable transaction at such time on an arm’s-length basis by the Issuer or that Restricted Subsidiary from a Person that is not an Affiliate of the Issuer or that Restricted Subsidiary; and

(2) the Issuer delivers to the Trustee with respect to any Affiliate Transaction involving aggregate value in excess of $20.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by the Independent Directors approving such Affiliate Transaction.

(1) transactions exclusively between or among (a) the Issuer and one or more Restricted Subsidiaries or (b) Restricted Subsidiaries;

(2) reasonable director, officer and employee compensation (including bonuses) and other benefits (including pursuant to any employment agreement or any retirement, health, stock option or other benefit plan) and indemnification and insurance arrangements, in each case, as determined in good faith by the Issuer’s Board of Directors or senior management;

(3) the entering into of a tax sharing agreement, or payments pursuant thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Issuer and the Restricted Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis;

(4) any Permitted Investments;

(5) any Restricted Payments which are made in accordance with Section 4.11;

(6)(x) any agreement in effect on the Issue Date, as in effect on the Issue Date or as thereafter amended or replaced in any manner that, taken as a whole, is not more disadvantageous to the Holders or the Issuer in any material respect than such agreement as it was in effect on the Issue Date or (y) any transaction pursuant to any agreement referred to in the immediately preceding clause (x);

(7) any transaction with a Person (other than an Unrestricted Subsidiary) which would constitute an Affiliate of the Issuer solely because the Issuer or a Restricted Subsidiary owns an equity interest in or otherwise controls such Person;

(10) pledges by the Issuer or any Restricted Subsidiary of Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Unrestricted Subsidiaries;

Section 4.14. Limitation on Liens.

The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (other than Permitted Liens) of any nature whatsoever against any assets of the Issuer or any Restricted Subsidiary (including Equity Interests of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, which Lien secures Indebtedness. Notwithstanding anything to the contrary contained in this Indenture or the Security Documents, the Issuer will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pledge any Equity Interest of the Issuer or any of the Restricted Subsidiaries to secure Indebtedness of the Issuer or any Guarantor, other than Liens securing the Notes or any Senior Obligation and as otherwise required as a matter of law.

Section 4.15. Change of Control.

(a) Upon the occurrence of any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described in paragraph 5 of the Notes, each Holder will have the right to require that the Issuer purchase all or any portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(j) Notwithstanding anything to the contrary in this Indenture, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

-52-

(8) any other agreement governing Indebtedness or other obligations entered into after the Issue Date that contains encumbrances and restrictions that in the good faith of the Issuer are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date;

Section 4.18. Conduct of Business.

The Issuer shall engage, and shall cause its Restricted Subsidiaries to engage, only in businesses that, when considered together as a single enterprise, are primarily the Permitted Business.

Section 4.19. Limitations on Designation of Unrestricted Subsidiaries.

(a) The Issuer may designate any Subsidiary (including any newly formed or newly acquired Subsidiary) of the Issuer as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

-53-

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to clause (a) of Section 4.11, in either case in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

(b) No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless:

(1) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the time of Designation, consist of Non-Recourse Debt, except any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary, and except for any Contingent Obligations of the Issuer or any Restricted Subsidiary in respect of Indebtedness of such Unrestricted Subsidiary that is permitted as both an incurrence of Indebtedness and an Investment (in each case in an amount equal to the amount of such Indebtedness so guaranteed) permitted by Sections 4.10 and 4.11);

(2) on the date such Subsidiary is Designated an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding (other than Contingent Obligations permitted under clause (1) above) with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding, taken as a whole, are not materially less favorable to the Issuer or the Restricted Subsidiary than those that could reasonably be expected to have been obtained at the time from Persons who are not Affiliates of the Issuer, as determined in good faith by the Issuer;

(3) such subsidiary is a Person with respect to which neither the Issuer nor any Restricted Subsidiary has any direct or indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results (in each case other than Contingent Obligations permitted under clause (1) above); and

(4) such subsidiary has not guaranteed or otherwise directly or indirectly provided credit support for any Indebtedness of the Issuer or any Restricted Subsidiary, except for any pledge of the Equity Interests of such Unrestricted Subsidiary to secure Indebtedness of the Issuer or any Restricted Subsidiary.

(c) If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.10 or the Lien is not permitted under Section 4.14, the Issuer shall be in default of the applicable Section.

Section 4.20. Additional Note Guarantees.

If, after the Issue Date, (a) the Issuer or any Restricted Subsidiary shall acquire or create another Domestic Restricted Subsidiary, or (b) any Unrestricted Subsidiary is Redesignated a Domestic Restricted Subsidiary, and (in each such case) such Domestic Restricted Subsidiary guarantees any Indebtedness under any Credit Facility, then the Issuer shall, within 15 Business Days, cause such Domestic Restricted Subsidiary to:

(1) execute and deliver to the Trustee a supplemental indenture substantially in the form prescribed by this Indenture pursuant to which such Domestic Restricted Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and this Indenture; and

(2) deliver to the Trustee the Opinion of Counsel required by Section 10.07 hereof.

In addition, each such Domestic Restricted Subsidiary which, from time to time, shall become a Guarantor shall execute and deliver to the Collateral Agent a joinder agreement to the Security Agreement and otherwise comply with all the requirements of the Security Agreement.

Section 4.21. Limitations on Layering Indebtedness.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness that is or purports to be by its terms (or by the terms of any agreement governing such Indebtedness) subordinated in right of payment to any other Indebtedness of the Issuer or of such Restricted Subsidiary, as the case may be, unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate in right of payment to the Notes or the Note Guarantee of such Restricted Subsidiary, to the same extent and in the same manner as such Indebtedness is subordinated to such other Indebtedness of the Issuer or such Restricted Subsidiary, as the case may be.

(b) For purposes of the foregoing, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Issuer or any Restricted Subsidiary solely by virtue of being unsecured or secured by a Permitted Lien or by virtue of the fact that the holders of such Indebtedness have entered into intercreditor agreements or other arrangements giving one or more of such holders priority over the other holders in the collateral held by them or other payments among them.

Section 4.22. [Reserved].

Section 4.23. Suspension of Covenants.

(a) During any period of time that the Notes have a Xxxxx’x rating of “Baa3” or higher and an S&P rating of “BBB-” or higher (each, an “Investment Grade Rating”) and no Default has occurred and is then continuing, the Issuer and the Restricted Subsidiaries will not be subject to the following covenants: Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.16, Section 4.18, Section 4.20, Section 4.21 and Section 5.01(a)(3) (collectively, the “Suspended Covenants”).

(b) In the event that the Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the preceding sentence and, subsequently, one or both of the Rating Agencies, as applicable, withdraws its ratings or downgrades the ratings assigned to the Notes such that the Notes do not have an Investment Grade Rating, then the Issuer and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants, it being understood that no actions taken by (or omissions of) the Issuer or any of its Restricted Subsidiaries during the suspension period shall constitute a Default or an Event of Default under the Suspended Covenants. Furthermore, after the time of reinstatement of the Suspended Covenants upon such withdrawal or downgrade, calculations with respect to Restricted Payments will be made in accordance with the terms of the covenant described above under Section 4.11 as though such covenant had been in effect during the entire period of time from the Issue Date.

-55-

Section 4.24. Payment of Additional Amounts by a Foreign Successor Issuer.

(a) All payments made under or with respect to the Notes or any Note Guarantee by any Foreign Successor Issuer or any Guarantor of a Foreign Successor Issuer (each such person, a “Payor”) will be made free and clear of any withholding or deduction for or on account of any tax, duty, levy, impost, assessment or other governmental charge of whatever nature (collectively, “Tax”) imposed or levied by or on behalf of any jurisdiction in which such Payor is organized, resident or doing business for tax purposes or from or through which such Payor (or any of its agents) makes any payment on the Notes or any Note Guarantee or any department or political subdivision of any of the foregoing (each, a “Relevant Taxing Jurisdiction”), unless such Payor or other applicable withholding agent is required to withhold or deduct Taxes by law. For the avoidance of doubt, a Relevant Taxing Jurisdiction shall not include the United States, any state thereof or the District of Columbia. If a Payor or other applicable withholding agent is required by law to withhold or deduct any amount for or on account of Taxes of a Relevant Taxing Jurisdiction from any payment made under or with respect to the Notes or any Note Guarantee, the Payor, subject to the exceptions listed below, will pay additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by each Holder of the Notes after such withholding or deduction (including withholding or deduction attributable to Additional Amounts payable hereunder) will not be less than the amount the Holder would have received if such Taxes had not been withheld or deducted.

(b) A Payor will not, however, pay Additional Amounts to a Holder or beneficial owner of Notes:

(i) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the Holder’s or beneficial owner’s present or former connection with the Relevant Taxing Jurisdiction (other than any connection resulting from the acquisition, ownership, holding or disposition of Notes, the receipt of payments thereunder or under any Note Guarantee and/or the exercise or enforcement of rights under any Notes or any Note Guarantee);

(ii) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the failure of the Holder or beneficial owner of Notes, following the Payor’s written request address to the Holder, to the extent such Holder or beneficial owner is legally eligible to do so, to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or administrative practice of a Relevant Taxing Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Relevant Taxing Jurisdiction (including, without limitation, a certification that the Holder or beneficial owner is not resident in the Relevant Taxing Jurisdiction);

(iii) with respect to any estate, inheritance, gift, sales or any similar Taxes;

(iv) if such Holder is a fiduciary or partnership or person other than the sole beneficial owner of such payment and the Taxes giving rise to such Additional Amounts would not have been imposed on such payment had the Holder been the beneficiary, partner or sole beneficial owner, as the case may be, of such Notes (but only if there is no material cost or expense associated with transferring such Notes to such beneficiary, partner or sole beneficial owner and no restriction on such transfer that is outside the control of such beneficiary, partner or sole beneficial owner);

(v) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed but for the presentation by the Holder of any Notes, where presentation is required, for payment on a date more than 30 days after the date of which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(vi) with respect to any withholding or deduction that is imposed pursuant to the European Council Directive on the taxation of savings income which was adopted by the ECOFIN Council on June 3, 2003 or any law implementing or complying with, or introduced in order to conform to such directive (the “EU Savings Tax Directive”) or is required to be made pursuant to the Agreement between the European Community and the Swiss Confederation dated October 26, 2004 providing for measures equivalent to those laid down in the EU Savings Tax Directive (the “EU-Swiss Savings Tax Agreement”) or any law or other governmental regulation implementing or complying with, or introduced in order to conform to, such agreement;

-56-

(vii) with respect to any tax that is payable other than by deduction or withholding at source; or

(viii) any combination of items (i), (ii), (iii), (iv), (v), (vi) and (vii).

(c) A Payor will (i) make any such withholding or deduction required by applicable law and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Payor will make reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes. The Payor will provide to the Trustee, within a reasonable time after the date the payment of any Taxes so deducted or withheld are due pursuant to applicable law, either a certified copy or tax receipts evidencing such payment, or, if such tax receipts are not reasonably available to the Payor, such other documentation that provides reasonable evidence of such payment by the Payor.

(d) The Payor will deliver to the Trustee any Additional Amounts payable together with an Officers’ Certificate stating that such Additional Amounts will be payable prior to the date on which such payments will be made, and will include such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date. Any such Officers’ Certificate will be delivered a reasonable time in advance of when the payments in question are required to be made. The Payor will promptly publish a notice in accordance with Section 11.02 hereof stating that such Additional Amounts will be payable and describing the obligation to pay such amounts.

(e) The Payors, jointly and severally, will reimburse the Holders of the Notes, upon written request of such Holder of the Notes and appropriate proof of payment for the amount of (i) any Taxes levied or imposed by a Relevant Taxing Jurisdiction and payable by such Holder or the applicable beneficiary in connection with payments made under or with respect to the Notes held by such Holder or any Note Guarantee; and (ii) any Taxes levied or imposed with respect to any reimbursement under the foregoing clause (i) or this clause (ii), so that the net amount received by the beneficial owner after such reimbursement will not be less than the net amount such beneficial owner would have received if the Taxes giving rise to the reimbursement described in clauses (i) and/or (ii) had not been imposed, provided, however, that the indemnification obligation provided for in this Section 4.24(e) shall not extend to Taxes imposed for which the Holder or beneficial owner would not have been eligible to receive payment of Additional Amounts hereunder by virtue of clauses (i) through (viii) of Section 4.24(b) hereof, or to the extent such Holder or beneficial owner received Additional Amounts with respect to such payments.

(f) In addition, a Foreign Successor Issuer will pay any stamp, issue, registration, court, documentary, excise or other similar taxes, charges and duties (including interest, additions to tax and penalties with respect thereto) imposed by any Relevant Taxing Jurisdiction at any time on or after the date on which the Foreign Successor Issuer becomes a Foreign Successor Issuer (the “Successor Date”) in respect of the execution, issuance, registration or delivery of the Notes, any Note Guarantee or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction at any time on or after the Successor Date as a result of, or in connection with, (i) any payments made pursuant to the Notes, any Note Guarantee or any other such document or instrument referred to thereunder and/or (ii) the enforcement of the Notes any Note Guarantee or any other such document or instrument referred to thereunder.

(g) The obligations described under this Section 4.24 will survive any termination, defeasance or discharge of this Indenture and will apply mutatis mutandis to any successor Person, to any Payor, and to any jurisdiction (other than the United States, any state thereof or the District of Columbia) in which such successor is organized, resident or doing business for Tax purposes or any jurisdiction from or through which payment is made by such successor or its agents.

(h) Whenever this Indenture refers to, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Note or under any Note Guarantee, such reference includes the payment of Additional Amounts or indemnification payments that would be payable pursuant to this Section 4.24, if applicable.

-57-

Section 4.25. Post-Closing Matters.

Within five days of the Issue Date (or such longer period of time as Collateral Agent in its sole discretion shall permit), the Collateral Agent shall have received the opinion of Xxxxxx and Xxxxxx, counsel to the Company in form and substance previously agreed upon.

Section 6.02. Acceleration.

If an Event of Default (other than an Event of Default specified in Section 6.01(g) or (h) with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. (The Trustee agrees to provide a copy of such notice to such other Persons as may be required by the Security Documents.) Upon such declaration of acceleration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable (a) if there is no Indebtedness outstanding under any Senior Facility at such time, immediately and (b) if otherwise, subject to any limitations in the Intercreditor Agreement, unless the Collateral Termination has occurred, and if the Collateral Termination has occurred upon the earlier of (x) the final maturity (after giving effect to any applicable grace period or extensions thereof) or an acceleration of any Indebtedness under any Credit Facility prior to the express final stated maturity thereof and (y) five Business Days after the Authorized Representative under each Credit Facility receives the acceleration declaration, but, in the case of this clause (b), only if such Event of Default is then continuing; provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of such outstanding Notes may rescind and annul such acceleration if:

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

(2) all Events of Default, other than nonpayment of principal or interest that has become due solely because of the acceleration, have been cured or waived;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

-61-

(4) the Issuer has paid all sums paid or advanced by the Trustee hereunder and its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and those of its agents and counsel; and

(5) in the event of the cure or waiver of an Event of Default of the type described in Section 6.01(g) or (h) above, the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right consequent thereto. If an Event of Default specified in Section 6.01(g) or (h) occurs with respect to the Issuer and is continuing, then, to the extent permitted by applicable law, all unpaid principal of and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

Section 6.03. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of and interest on the Notes or to enforce the performance of any provision of the Notes, this Indenture, or the Security Documents and may take any necessary action requested of it as Trustee to settle, compromise, adjust or otherwise conclude any proceedings to which it is a party.

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. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults and Events of Default.

Subject to Sections 2.09, 6.02, 6.07 and 8.02 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding have the right to waive past Defaults under this Indenture except a Default or Event of Default in the payment of the principal of or interest on any Note as specified in clauses (a) and (b) of Section 6.01 or in respect of a covenant or a provision which cannot be modified or amended without the consent of all Holders as provided for in Section 8.02. The Issuer shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of Holders have consented to such waiver. In case of any such waiver, the Issuer, the Trustee and the Holders shall be restored to their former positions and rights hereunder and under the Notes, respectively. This paragraph of this Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereto.

Section 6.05. Control by Majority.

Subject to Section 2.09 hereof, the Holders of a majority in aggregate principal amount of the outstanding Notes have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee by this Indenture. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or any Security Document or that the Trustee determines may be unduly prejudicial to the rights of another Holder not taking part in such direction, and the Trustee shall have the right to decline to follow any such direction if the Trustee, being advised by counsel, determines that the action so directed may not lawfully be taken or if the Trustee in good faith shall, by a Trust Officer, determine that the proceedings so directed may involve it in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. In the event the Trustee takes any action or follows any direction pursuant to this Indenture or the Security Documents, the Trustee shall be entitled to indemnification reasonably satisfactory to it against any loss or expense caused by taking such action or following such direction. This Section 6.05 shall be in lieu of Section 316(a)(1)(A) of the TIA, and such Section 316(a)(1)(A) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA.

-62-

Section 6.06. Limitation on Suits.

(a) Subject to Section 6.07 below, no Holder shall have any right to institute any proceeding with respect to this Indenture or any remedy thereunder unless:

(1) such Holder has given the Trustee written notice of a continuing Event of Default;

(2) the Holders of at least 25% in aggregate principal amount of outstanding Notes have made a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense;

(4) the Trustee fails to institute such proceeding within 60 days after receipt of the request and the offer of indemnity; and

(5) the Trustee has not received directions inconsistent with such written request during such 60-day period by the Holders of a majority in aggregate principal amount of the outstanding Notes.

(b) However, such limitations do not apply to the right of any Holder of a Note to receive payment of the principal of, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, which right will not be impaired or affected without the consent of the Holder.

Section 6.07. Rights of Holders To Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of or accrued interest on any Note held by such Holder on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee.

If an Event of Default occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and interest on overdue installments of interest, in each case at the rate set forth in Section 4.01 hereof, and such further amounts 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 6.09. Trustee May File Proofs of Claim.

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (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 on the Notes), its creditors or its property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same after deduction of its charges and expenses to the extent that any such charges and expenses are not paid out of the estate in any such proceedings 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 7.07 hereof.

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 or reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceedings.

Section 6.10. Priorities.

Any money collected by the Trustee pursuant to this Article or any Security Document and any other money or property distributable in respect of the Issuer’s obligations under this Indenture or any Security Document after an Event of Default shall be applied in the following order:

FIRST: to the Trustee (including any predecessor Trustee) for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

TRUSTEE

Section 7.01. 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 the Security Documents and use the same degree of care and skill in their exercise thereof as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

-64-

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

(1) The Trustee need perform only those duties as are specifically set forth in this Indenture and the Security Documents and no covenants or obligations shall be implied in this Indenture or the Security Documents against the Trustee.

However, the Trustee shall examine the certificates and opinions which are specifically required to be delivered to the Trustee by any provision of this Indenture or any Security Document to determine in good faith whether or not they conform to the requirements of this Indenture or such Security Document.

(c) Notwithstanding anything to the contrary herein contained, the Trustee may not be relieved from liability for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that:

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

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

(e) Whether or not herein expressly provided, every provision of this Indenture or any Security Document that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.01.

(f) The Trustee shall not be liable for interest on any money or assets received by it except as the Trustee may agree in writing with the Issuer. Assets held in trust by the Trustee need not be segregated from other assets except to the extent required by law.

(i) The rights, privileges, protections, immunities and benefits given to the Trustee in this Indenture, including, without limitation, its right to be indemnified and any limitations on its duties and liabilities under this Indenture and the Security Documents, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including its capacity as Registrar, Paying Agent and agent for services of notices and demands) and under each Security Document (including its capacity as Collateral Agent and as “Authorized Representative,” “Senior Representative,” “Senior Class Debt Representative” and, if applicable, “Controlling Agent” under the Intercreditor Agreement), and each agent, custodian and other Person employed to act hereunder or thereunder.

-65-

(j) The permissive right of the Trustee to take or refrain from taking any actions enumerated in this Indenture or any Security Document shall not be construed as a duty.

(k) The Trustee has no duty to determine whether the Issuer and the Guarantors are in compliance with the terms of the Credit Agreement or any other Credit Facility.

Subject to Section 7.01 hereof:

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

(b) Before the Trustee acts or refrains from acting with respect to any matters contemplated by this Indenture, any Security Document or the Notes it may consult with counsel and may require an Officers’ Certificate or an Opinion of Counsel, or both, which shall conform to the provisions of Section 11.05 hereof. The Trustee shall be protected and shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion.

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

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in reliance thereon.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture or any Security Document at the request or direction of any of the Holders pursuant to this Indenture or any Security Document, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

(g) The Trustee may request that the Issuer deliver an Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture or any Security Document, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

(h) The Trustee shall not be responsible or liable for any failure or delay in the performance of its obligations under this Indenture or any Security Document arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority and governmental action.

-66-

(i) Anything in this Indenture or any Security Document notwithstanding, in no event shall the Trustee be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Issuer has been advised as to the likelihood of such loss or damage and regardless of the form of action.

Section 7.03. Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for or otherwise deal with the Issuer, or any Affiliates thereof, with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. The Trustee, however, shall be subject to Sections 7.10 and 7.11 hereof.

Section 7.04. Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to (i) the validity or adequacy of this Indenture, any Security Document or the Notes, (ii) whether a Default or Event of Default has occurred and is continuing or will occur upon the execution and delivery of the Indenture or any Security Document or upon the issuance of the Notes, (iii) whether each Holder constitutes an “Additional Senior Debt Party,” a “Senior Class Debt Party” or a “Senior Secured Party,” whether the Note Obligations constitute “Additional Senior Debt” or “Senior Class Debt,” whether the Indenture constitutes an “Additional Senior Debt Facility” or a “Senior Facility,” or whether the Indenture, the Notes, and the Security Documents constitute “Additional Senior Debt Documents” or “Senior Debt Documents,” in any such case, under the Intercreditor Agreement, or (iv) whether the conditions in Section 5.12 of the Intercreditor Agreement have been satisfied in order for the Trustee, in its capacity as Collateral Agent, to become a party to the Intercreditor Agreement as an “Authorized Representative,” “Senior Class Debt Representative” and a “Senior Representative.” Trustee shall not be accountable for the Issuer’s use of the proceeds from the sale of Notes or any money paid to the Issuer pursuant to the terms of this Indenture or any Security Document and it shall not be responsible for any statement of the Issuer in this Indenture, the Security Documents or the Notes other than the Trustee’s certificate of authentication.

Section 7.05. Notice of Defaults.

The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has received written notice of such Default or Event of Default at the Corporate Trust Office of the Trustee.

Within 90 days after the occurrence of any Default or Event of Default hereunder, the Trustee shall transmit by mail to Holders of Notes, as their names and addresses appear in the records of the Registrar, a notice of the Default or Event of Default known to the Trustee, unless such Default or Event of Default shall have been cured or waived. Except in the case of an Event of Default in payment of principal of or interest on any Note, including an accelerated payment and the failure to make payment on the Change of Control Payment Date pursuant to a Change of Control Offer or on the Offer Payment Date pursuant to a Net Proceeds Offer, the Trustee may withhold the notice if and so long as its Board of Directors, the executive committee of its Board of Directors or a committee of its directors and/or Trust Officers in good faith determines that withholding the notice is in the interest of the Holders. This Section 7.05 shall be in lieu of the proviso to Section 315(b) of the TIA, and such proviso of Section 315(b) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA.

Section 7.06. Reports by Trustee to Holders.

If required by TIA Section 313(a), within 60 days after May 15 of any year, commencing the first May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee also shall comply with TIA Section 313(b), (c) and (d). Reports pursuant to this Section 7.06 shall be transmitted by mail:

-67-

(a) to all registered Holders, as the names and addresses of such Holders appear on the Registrar’s books; and

(b) to such Holders as have, within the two years preceding such transmission, filed their names and addresses with the Trustee for that purpose.

A copy of each report at the time of its mailing to Holders shall be filed with the Commission and each stock exchange, if any, on which the Notes are listed. The Issuer shall promptly notify the Trustee when the Notes are listed on any stock exchange or of any delisting thereof.

Section 7.07. Compensation and Indemnity.

The Issuer shall pay to the Trustee from time to time such compensation as shall be agreed in writing between the Issuer and the Trustee for the Trustee’s services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee upon request for all reasonable fees and expenses, including out-of-pocket expenses incurred or made by it in connection with the performance of its duties under this Indenture or any Security Document or in connection with the collection of any funds. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel.

The Issuer shall indemnify each of the Trustee and its agents, employees, stockholders and directors and officers for, and hold them harmless against, any loss, liability or expense incurred by them (including attorney’s fees and expenses) arising out of or in connection with the administration of this trust or any security interest created under the Security Documents, including the reasonable costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties hereunder or under any Security Document, except for such actions to the extent caused by any gross negligence, bad faith or willful misconduct on their part as determined by a court of competent jurisdiction in a final order. The Trustee shall notify the Issuer promptly, in writing, of any claim asserted against the Trustee for which it may seek indemnity. At the Trustee’s sole discretion, the Issuer shall defend the claim and the Trustee shall cooperate and may participate in the defense; provided that any settlement of a claim shall be approved in writing by the Trustee. The Issuer need not pay for any settlement made without its written consent, which consent shall not be unreasonably withheld. The Issuer need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee through its gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction in a final order.

To secure the Issuer’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Notes on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or interest on particular Notes.

In addition and without prejudice to the rights provided to the Trustee under any provision of this Indenture or any Security Document, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(f) or (g) hereof occurs, such expenses and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law.

The obligation of the Issuer under this Section 7.07 shall survive the resignation or removal of the Trustee and the termination or satisfaction and discharge of this Indenture or any Security Document.

“Trustee” for purposes of this Section shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and under the Security Documents (including its capacity as Collateral Agent and as “Authorized Representative,” “Senior Representative” and, if applicable, “Controlling Agent” under the Intercreditor Agreement) and to each agent, custodian and other person employed to act hereunder; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder or under any Security Document shall not affect the rights of any other Trustee hereunder or under any Security Document.

-68-

Section 7.08. Replacement of Trustee.

The Trustee may resign at any time by so notifying the Issuer in writing. The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing and may appoint a successor Trustee. The Issuer may remove the Trustee at its election if:

(a) the Trustee fails to comply with Section 7.10 hereof;

(b) the Trustee is adjudged a bankrupt or an insolvent;

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

(d) the Trustee otherwise 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 Trustee in such event being referred to herein as the retiring Trustee), the Issuer shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Immediately after that, the retiring Trustee shall transfer, after payment of all sums then owing to the Trustee pursuant to Section 7.07 hereof, all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.07 hereof, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have the rights, powers and duties of the Trustee under this Indenture and each Security Document. A successor Trustee shall mail notice of its succession to each Holder.

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

If the Trustee, after written request by any Holder who has been a bona fide holder of securities for any period of time specified under TIA Section 310(b), fails to comply with Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Consolidation, Merger or Conversion.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, subject to this Article 7, the successor corporation without any further act shall be the successor Trustee.

Section 7.10. Eligibility; Disqualification.

This Indenture shall always have a Trustee which shall be eligible to act as Trustee under TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. If the Trustee has or shall acquire any “conflicting interest” within the meaning of TIA Section 310(b), the Trustee and the Issuer shall comply with the provisions of TIA Section 310(b); provided, however, that there shall be excluded from the operation of TIA Section 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.10, the Trustee shall resign immediately in the manner and with the effect hereinbefore specified in this Article 7.

-69-

Section 7.11. Preferential Collection of Claims Against the Issuer.

The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. The provisions of TIA Section 311 shall apply to the Issuer and the Guarantors as obligors upon the Notes.

ARTICLE 8

AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 8.01. Without Consent of Holders.

(a) The Issuer and the Guarantors, when authorized by a Board Resolution, and the Trustee or, if applicable, the Collateral Agent (including in its capacity as “Notes Collateral Agent,” “Authorized Representative,” “Senior Representative,” “Senior Class Debt Representative,” or “Controlling Agent” under the Intercreditor Agreement) may amend or supplement this Indenture, the Security Documents, the Notes, the Note Guarantees or the Intercreditor Agreement without notice to or consent of any Holder:

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

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

(10) to conform the text of this Indenture or the Notes to any provision of the Description of the Secured Notes section of the Offering Memorandum to the extent that such provision in the Description of the Secured Notes was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees or the Notes;

(11) in the case of the Intercreditor Agreement, in order to subject the security interests in the Collateral in respect of any Additional Senior Debt Obligations and Senior Loan Obligations to the terms of the Intercreditor Agreement, in each case to the extent the Incurrence of such Indebtedness, and the grant of all Liens on the Collateral held for the benefit of such Indebtedness, were permitted under this Indenture;

(12) to provide for the issuance of Additional Notes in accordance with this Indenture; or

-70-

(13) with respect to any Security Document, to the extent such amendment is reasonably necessary to comply with the terms of the Intercreditor Agreement (including Section 2.04(c) thereof).

Section 8.02. With Consent of Holders.

(a) Subject to Section 6.07 hereof, the Issuer and the Guarantors, when each is authorized by a Board Resolution of their respective Boards of Directors, and the Trustee or, if applicable, the Collateral Agent (including in its capacity as “Notes Collateral Agent,” “Authorized Representative,” “Senior Representative,” “Senior Class Debt Representative,” or “Controlling Agent” under the Intercreditor Agreement) may amend or supplement this Indenture, Security Documents, the Notes, the Note Guarantees or the Intercreditor Agreement with the consent (which may include consents obtained in connection with a tender offer or exchange offer for the Notes) of the Holders of at least a majority in principal amount of the Notes then outstanding. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive any existing Defaults under, or compliance by the Issuer or any Guarantor with any provision of, this Indenture, the Security Documents, the Notes, or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04 hereof, may not:

(1) reduce, or change the maturity of, the principal of any Note;

(2) reduce the rate of or extend the time for payment of interest on any Note;

(3) reduce any premium payable upon redemption of the Notes, change the date on which any Notes are subject to redemption or waive any payment with respect to the redemption of the Notes; provided, however, that solely for the avoidance of doubt, and without any other implication, any purchase or repurchase of Notes (including pursuant to Section 4.12 and Section 4.15) shall not be deemed a redemption of the Notes;

(4) make any Note payable in money or currency other than that stated in the Notes;

(5) modify or change any provision of this Indenture or the related definitions to affect the ranking of the Notes or any Note Guarantee in a manner that adversely affects the Holders;

(6) reduce the percentage of Holders necessary to consent to an amendment or waiver to this Indenture or the Notes;

(7) waive a default in the payment of principal of or interest on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in this Indenture and a waiver of the payment default that resulted from such acceleration);

(8) impair the rights of Holders to receive payments of principal of or interest on the Notes on or after the due date therefor or to institute suit for the enforcement of any payment on the Notes;

(9) release any Guarantor that is a Significant Subsidiary from any of its obligations under its Note Guarantee or this Indenture, except as permitted by this Indenture; or

(10) make any change in these amendment, supplement and waiver provisions.

Furthermore, without the consent of the Holders of at least two-thirds in principal amount of the Notes then outstanding, an amendment or waiver may not make any change in any Security Document, any Intercreditor Agreement or the provisions in this Indenture dealing with the Collateral or the Security Documents or the application of trust proceeds of the Collateral that would release all or substantially all of the Collateral from the Liens of the Security Documents (except as permitted by the terms of this Indenture, the Security Documents and the Intercreditor Agreement (including Section 2.04 thereof)) or change or alter the priority of the security interests in the Collateral.

-71-

The consent of the Holders of the Notes is not necessary under this Indenture, the Intercreditor Agreement or any Security Document to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver.

After an amendment or supplement under this Section 8.02 becomes effective, the Issuer shall mail to Holders of the Notes a notice briefly describing such amendment or supplement. However, the failure to give such notice to all Holders of the Notes, or any defect therein, will not impair or affect the validity of the amendment or supplement.

Section 8.03. Compliance with TIA.

Every amendment to or supplement of this Indenture, the Notes or the Note Guarantees shall comply with the TIA as then in effect.

Section 8.04. Revocation and Effect of Consents.

Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder 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. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Note or portion of such Note by notice to the Trustee and, if applicable, the Collateral Agent or the Issuer received before the date on which the Trustee and, if applicable, the Collateral Agent receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.

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 last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled 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 90 days after such record date.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (1) through (10) of Section 8.02 hereof, in which case, the amendment, supplement or waiver shall bind only each Holder who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note.

Section 8.05. Notation on or Exchange of Notes.

If an amendment, supplement, or waiver changes the terms of a Note, the Trustee may request the Holder to deliver it to the Trustee. In such case, the Trustee shall place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Issuer or the Trustee so determines, in exchange for the Note the Issuer shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. 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 8.06. Trustee and Collateral Agent To Sign Amendments, etc.

Each of the Trustee and the Collateral Agent shall be entitled to receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of any amendment, supplement or waiver authorized pursuant to this Article 8 is authorized or permitted by this Indenture and the Security Documents and that such amendment, supplement or waiver constitutes the legal, valid and binding obligation of the Issuer and any Guarantors, enforceable in accordance with its terms (subject to customary exceptions). Each of the Trustee and the Collateral Agent may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee’s or the Collateral Agent’s own rights, duties or immunities under this Indenture or the Security Documents or otherwise.

If payment at stated maturity of less than all of the Notes of any series is to be provided for in the manner and with the effect provided in this Section 9.01, the Trustee shall select such Notes, or portions or principal amount thereof, in the manner specified by Section 3.02 for selection for redemption of less than all the Notes of a series.

Section 9.02. Legal Defeasance.

(a) The Issuer may, at its option at any time, elect to have this Section be applied to all outstanding Notes upon compliance with the conditions set forth in Section 9.04.

-73-

(b) Upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), the Issuer and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be deemed to have been discharged from their respective obligations with respect to all outstanding Notes and the Note Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and each Guarantor shall be deemed to have paid and discharged the entire obligations represented by the Notes and the Note Guarantees, and this Indenture shall cease to be of further effect as to all outstanding Notes and the Note Guarantees, except as to: (i) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 9.05 hereof, and as more fully set forth in such Section, payments in respect of the principal of and interest on such Notes when such payments are due from such trust fund, (ii) the Issuer’s obligations with respect to the Notes under Article 2 and Section 4.07 hereof, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s obligations in connection therewith and (iv) this Article 9. Subject to compliance with this Article 9, the Issuer may exercise its option under this Section 9.02 notwithstanding the prior exercise of its option under Section 9.03 below with respect to the Notes.

Section 9.03. Covenant Defeasance.

(a) The Issuer may, at its option at any time, elect to have this Section be applied to all outstanding Notes upon compliance with the conditions set forth in Section 9.04.

(b) Upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), the Issuer and each Guarantor shall, subject to the satisfaction of the conditions set forth in Section 9.04 hereof, be released from their respective obligations under the covenants contained in Sections 4.02, 4.05 and 4.08 through 4.21 hereof, inclusive, and subclause (3) of Section 5.01(a) hereof with respect to the outstanding Notes and the Note Guarantees on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”); provided, however, that Covenant Defeasance will not be effective until such time as Events of Default contained in Section 6.01(g) and (h) no longer apply, and the Notes and the Note Guarantees 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. For this purpose, such Covenant Defeasance means that, with respect to the outstanding Notes and the Note Guarantees, the Issuer and each Guarantor 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 or Default under Section 6.01(d) hereof, but, except as specified above, the remainder of this Indenture, and such Notes and the Note Guarantees shall be unaffected thereby. In addition, upon the Issuer’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), subject to the satisfaction of the conditions set forth in Section 9.04 hereof, the Events of Default described under clauses (c) through (f), (i) and (j) of Section 6.01 and the Events of Default described under clauses (g) and (h) of Section 6.01 (but only with respect to Significant Subsidiaries of the Issuer), in each case, will no longer constitute an Event of Default.

Section 9.04. Conditions to Legal Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of either Section 9.02 or 9.03 hereof to the outstanding Notes and the Note Guarantees:

(1) the Issuer must irrevocably deposit with the Trustee (or other qualifying trustee), as trust funds, in trust solely for the benefit of the Holders, U.S. legal tender or U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest), in the opinion of a nationally recognized investment bank, appraisal firm or firms of independent public accountants selected by the Issuer, to pay the principal of and interest on the Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be;

(2) in the case of an election under Section 9.02 hereof, the Issuer shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the

-74-

effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will 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 an election under Section 9.03 hereof, the Issuer shall have delivered to the Trustee an Opinion of Counsel confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will 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 Covenant Defeasance had not occurred;

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing);

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of or constitute a default under this Indenture or any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound (other than any such Default or default resulting solely from the borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowings);

(6) 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 preferring the Holders over any other creditors of the Issuer or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuer or others; and

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that the conditions precedent provided for in, in the case of the Officers’ Certificate, clauses (1) through (6) and, in the case of the Opinion of Counsel, clauses (2) and/or (3) and (5) of this Section 9.04 have been complied with.

If the funds deposited with the Trustee to effect Covenant Defeasance are insufficient to pay the principal of and interest on the Notes when due, then the Issuer’s obligations and the obligations of Guarantors under this Indenture will be revived and no such defeasance will be deemed to have occurred.

Section 9.05. Application of Trust Money.

All money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee pursuant to Section 9.01 or 9.04 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 as the Trustee may determine, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal and accrued interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer and the Guarantors shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 9.01 or 9.04 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.

Anything in this Article 9 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon a written request of the Issuer in the form of an Officers’ Certificate any money or U.S. Government Obligations held by it as provided in Section 9.01 or 9.04 hereof which, in the opinion of a nationally-recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent satisfaction and discharge of this Indenture, Legal Defeasance or Covenant Defeasance, as the case may be.

-75-

Section 9.06. Repayment to the Issuer.

Subject to Section 9.05 hereof, the Trustee and the Paying Agent shall promptly pay to the Issuer upon request any excess U.S. legal tender or U.S. Government Obligations held by them at any time and thereupon shall be relieved from all liability with respect to such money. Subject to applicable abandoned property laws, the Trustee and the Paying Agent shall pay to the Issuer upon request any money held by them for the payment of principal or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuer cause to be published once in a newspaper of general circulation in The City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed, and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Issuer. After payment to the Issuer, Holders entitled to such money must look to the Issuer for payment as general creditors unless an applicable law designates another Person.

Section 9.07. Reinstatement.

If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 9.01, 9.02 or 9.03 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 each Guarantor’s obligations under this Indenture, the Security Documents, the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to this Article 9 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. legal tender or U.S. Government Obligations in accordance with Section 9.01 hereof; provided, however, that if the Issuer or the Guarantors have made any payment of principal of or accrued interest on any Notes because of the reinstatement of their obligations, the Issuer and each such Guarantor shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE 10

GUARANTEES

Section 10.01. Unconditional Guarantee.

Each Guarantor hereby unconditionally, jointly and severally, guarantees to each Holder of a Note authenticated by the Trustee and to the Trustee and its successors and assigns that the principal of and interest on the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at the Maturity Date, by acceleration or otherwise, and interest on the overdue principal and interest on any overdue interest on the Notes, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or under the Notes will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 10.03 hereof. Each Guarantor hereby agrees that to the maximum extent permitted under applicable law, its 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. To the maximum extent permitted under applicable law, 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 the Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes, this Indenture and the Security Documents. If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by the Issuer or any Guarantor to the Trustee or such Holder, each Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, to the maximum extent permitted under applicable law, as between a Guarantor, 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 6 hereof for the purpose of each Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) shall become due and payable by each Guarantor for the purpose of each Note Guarantee.

-76-

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 Article 10.

Section 10.02. Severability.

In case any provision of this Article 10 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.

Section 10.03. Limitation on Guarantor’s Liability.

(a) To the extent applicable, a Guarantor’s liability in respect of its Note Guarantee shall be limited to the extent set forth below:

(1) Limitations Applicable to U.S. Guarantors. Each Guarantor that is incorporated, organized or formed, as the case may be, under the laws of the United States, any State thereof or the District of Columbia (a “U.S. Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm that it is the intention of all such parties that the Note Guarantee of a U.S. Guarantor does not constitute a fraudulent transfer or conveyance for purposes of Title 11 of the United States Code, as amended, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar U.S. Federal or state or other applicable law. To effectuate the foregoing intention, each Holder, by its acceptance of a Note, and each U.S. Guarantor hereby irrevocably agree that the obligations of a U.S. Guarantor under its Note Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such U.S. Guarantor (including, without limitation, any guarantees under any Credit Facility) and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such U.S. Guarantor not constituting such a fraudulent transfer or conveyance.

(2) Limitations Applicable to Other Guarantors. Each Guarantor that is incorporated, organized or formed, as the case may be, under the laws of any jurisdiction other than one set forth in clause (1) above (an “Other Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm that it is the intention of all such parties that the Note Guarantee of an Other Guarantor does not constitute a fraudulent transfer or conveyance for purposes of applicable law. To effectuate the foregoing intention, each Holder, by its acceptance of a Note, and each Other Guarantor hereby irrevocably agree that the obligations of an Other Guarantor under its Note Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Other Guarantor (including, without limitation, any guarantees under any Credit Facility) and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Note Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Other Guarantor not constituting such a fraudulent transfer or conveyance.

(b) If following the date of this Indenture and notwithstanding anything in Section 8.02 to the contrary:

(1) (i) there shall be any change in the laws of the United States, any State thereof or the District of Columbia or (ii) any Restricted Subsidiary incorporated, organized or formed, as the case may be, under the laws of any jurisdiction other than the United States, any State thereof or the District of Columbia (a “Future Guarantor”) shall be required to guarantee the Notes pursuant to Section 4.20 hereof and the Issuer shall reasonably determine that clause (2) with respect to Other Guarantors shall not adequately address the limitations on the Note Guarantee of such Future Guarantor imposed by applicable law of the jurisdiction of incorporation, organization or formation, as the case may be, of any such Future Guarantor; or

-77-

(2) the Issuer shall reasonably determine that it shall be necessary or advisable to amend the terms of subsection (a) of this Section 10.03 or to add additional provisions related to the limitations imposed on the Note Guarantee of a Future Guarantor,

then upon the delivery of an Officers’ Certificate and Opinion of Counsel reasonably satisfactory to the Trustee, the Issuer shall be entitled to amend such clauses or add such additional provisions (including any related modifications to the form of Note Guarantee attached hereto in Exhibit A), as the case may be, in order for the Note Guarantee of a Guarantor not to so violate applicable law.

(c) Each Guarantor that makes a payment for distribution under its Note Guarantee shall be entitled to a contribution from each other Guarantor in a pro rata amount based on adjusted net assets of each Guarantor.

Section 10.04. Successors and Assigns.

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

Section 10.05. No Waiver.

Each of the Guarantors agrees that to the maximum extent permitted under applicable law, (a) neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege and (b) the rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

Section 10.06. Release of Guarantor.

A Guarantor shall be released from all of its obligations under its Note Guarantee and its obligations under this Indenture and the Security Documents:

(1) in the event of a sale or other disposition of all or substantially all of the assets of such Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Equity Interests of such Guarantor then held by the Issuer and the Restricted Subsidiaries;

(2) if such Guarantor is designated as an Unrestricted Subsidiary or otherwise ceases to be a Restricted Subsidiary, in each case in accordance with the provisions of this Indenture, upon effectiveness of such designation or when it first ceases to be a Restricted Subsidiary;

(3) if such Guarantor is released from or otherwise ceases to guarantee any Credit Facility of the Issuer or any other Guarantor;

(4) in the event of the defeasance or discharge of this Indenture as described under Sections 9.01, 9.02 and 9.03; or

(5) dissolution of such Guarantor, provided no Default or Event of Default has occurred that is continuing.

Upon delivery by the Issuer to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that one of the foregoing requirements has been satisfied and the conditions to the release of a Guarantor from its Note Guarantee under this Section 10.06 have been met, the Trustee shall execute any documents reasonably required in order to evidence the release of such Guarantor from its obligations under its Note Guarantee.

-78-

Section 10.07. Execution of Supplemental Indenture for Future Guarantors.

Each Subsidiary which is required to become a Guarantor shall, and the Issuer shall cause each such Subsidiary to, promptly execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit E hereto pursuant to which such Subsidiary shall become a Guarantor under this Article 10 and shall guarantee the obligations of the Issuer under the Notes and this Indenture. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, each of such supplemental indenture and the Note Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms.

Section 10.08. Notation of Note Guarantee.

To evidence the Note Guarantee set forth in this Article 10, each Guarantor hereby agrees that a notation of such Note Guarantee shall be placed on each Note authenticated and made available for delivery by the Trustee and that this Note Guarantee shall be executed on behalf of each Guarantor by the manual or facsimile signature of an Officer of each Guarantor. Each Guarantor hereby agrees that the Note Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. If an Officer of a Guarantor whose signature is on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Note Guarantee is endorsed, the Note Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of each Guarantor.

Section 10.09. Subordination of Subrogation and Other Rights.

Each Guarantor hereby agrees that any claim against the Issuer that arises from the payment, performance or enforcement of such Guarantor’s obligations under the Note Guarantee or this Indenture, including, without limitation, any right of subrogation, shall be subject and subordinate to, and no payment with respect to any such claim of such Guarantor shall be made before, the payment in full in cash of all outstanding Notes in accordance with the provisions provided therefor in this Indenture.

the Intercreditor Agreement) that are subject to a Lien securing the Issuer’s and the Guarantors’ obligations under the Credit Agreement and (ii) the Issuer and the Guarantors agree that, unless a Collateral Termination has occurred, they will take all such action as shall be required to ensure that the Note Obligations will at all times be secured by a Lien, subject only to Permitted Liens, on all assets (except as provided in the Intercreditor Agreement) that in the future are subjected to a Lien to secure the Issuer’s existing and future Senior Obligations, which Lien shall be pursuant to documentation in form substantially similar to the documentation granting the Lien securing the relevant Senior Obligations, except as otherwise contemplated by the Intercreditor Agreement and except for differences consistent with the forms of Security Documents entered into on the Issue Date.

(b) This Indenture and the Security Documents (other than the Intercreditor Agreement) are subject to the terms, limitations and conditions set forth in the Intercreditor Agreement. Each Holder of a Note, by its acceptance of a Note, is deemed to have authorized and instructed the Collateral Agent to (i) execute and deliver, as a “Senior Class Debt Representative,” the Representative Supplement No.1 dated as of April 3, 2012, to the Intercreditor Agreement, (ii) act as its “Authorized Representative, “ “Senior Class Debt Representative,” and “Senior Representative,” in each case, under the Intercreditor Agreement, (iii) bind such Holder to the terms set forth in the Intercreditor Agreement as the same may be in effect or may be amended from time to time in accordance with its terms, and (iv) perform its obligations and exercise its rights thereunder in accordance therewith. In particular, each Holder of a Note, by its acceptance of a Note, (i) is deemed to agree that the Note Obligations constitute “Senior Class Debt” (under the Intercreditor Agreement) and that such Holder will be subject to and bound by the provisions of the Intercreditor Agreement as an “Additional Senior Debt Party” and a “Senior Class Debt Party” and (ii) is deemed to consent to the provisions of the Intercreditor Agreement and the other Security Documents providing for the release of the Liens on the Collateral and amendments to the Security Documents without the consent of any Holder of Notes. Each Holder, by accepting a Note, consents and agrees to all of the terms and provisions of the Security Documents, as the same may be amended from time to time pursuant to the terms of the Security Documents and this Indenture, and authorizes and directs the Collateral Agent to enter into the Security Documents on its behalf and on behalf of such Holder and to perform its obligations and exercise its rights thereunder and in accordance therewith. To the extent that any provision of this Indenture or any Security Document is not consistent with or contradicts the Intercreditor Agreement, the Intercreditor Agreement will govern.

(c) Any Person which, after the Issue Date, becomes a Guarantor under this Indenture, shall, upon becoming a Guarantor under this Indenture, become a party to each applicable Security Document (on terms and conditions substantially the same as the then current Collateral Documents) with respect to the assets or property of such Person that are Collateral, unless a Collateral Termination has occurred.

Section 12.02. Recording, Registration and Opinions; Trustee’s Disclaimer Regarding Collateral.

(a) Unless a Collateral Termination has occurred, the Issuer and, if applicable, the Guarantors shall take or cause to be taken all action required to perfect, maintain, preserve and protect the Lien on the Collateral granted by the Security Documents (subject only to Permitted Liens and to the terms of the Intercreditor Agreement), or that are otherwise required by Section 314(b) of the TIA, including without limitation, arranging for the filing of financing statements, continuation statements, mortgages and any instruments of further assurance, in such manner and in such places as may be required by law fully to preserve and protect the rights of the Holders and the Trustee and the Collateral Agent under this Indenture and the Security Documents to all property now or hereafter at any time comprising the Collateral. The Issuer shall from time to time promptly pay all financing, continuation statements and mortgage recording, registration and/or filing fees, charges and taxes relating to this Indenture and the Security Documents, any amendments thereto and any other instruments of further assurance required hereunder or pursuant to the Security Documents. Neither the Trustee nor the Collateral Agent shall have any obligation to, or shall it be responsible for any failure to, so register, file or record. Promptly after the execution and delivery of this Indenture, the Issuer shall furnish to the Trustee and Collateral Agent an Opinion of Counsel that complies with TIA Section 314(b)(1).

(b) Unless a Collateral Termination is in effect, the Issuer shall furnish to the Trustee and the Collateral Agent no later than August 1 of each year, beginning with 2013, an Opinion of Counsel which complies with Section 314(b)(2) of the TIA.

-83-

(c) Notwithstanding anything to the contrary set forth in this Indenture or in any other Security Document, neither the Trustee nor the Collateral Agent shall be responsible for the existence, genuineness or value of any of the Collateral, or for the creation, validity, perfection, priority or enforceability of the Liens in 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 of the Issuer 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.

Section 12.03. Possession, Use and Release of Collateral.

(a) Each Holder, by accepting a Note, consents and agrees to the provisions of the Intercreditor Agreement, the Security Documents and this Indenture governing the possession, use and release of Collateral. Each Holder, by accepting a Note, consents and agrees that Collateral may, and, as applicable, shall, be released or substituted in accordance with the terms of the Intercreditor Agreement and the Security Documents.

(b) In addition to the foregoing, Liens on Collateral securing Note Obligations will be entitled to be released under the following circumstances:

• in connection with a transaction that complies with Section 4.12 or in connection with a transaction that does not constitute an Asset Sale;

• in the event of the defeasance or discharge of this Indenture as described under Sections 9.01, 9.02 and 9.03;

• in the event the Notes obtain an Investment Grade Rating as described under Section 12.10; or

• as described under Article 8.

(c) The Collateral Agent shall execute and deliver all such authorizations and other instruments and take such actions (and the Holders will be deemed to have consented to and authorized the Collateral Agent to execute and deliver any such authorization or instrument and take any such action) as shall reasonably be requested by the Controlling Agent (as defined in the Intercreditor Agreement) to evidence, confirm and effectuate any release of Collateral provided for in Section 12.03(a) or (b).

(d) At the request of the Issuer and upon satisfaction of all applicable conditions to the permitted release of any Collateral (including the Collateral Agent’s receipt of any indemnity requested under Section 7.02), at the Issuer’s cost and expense, the Collateral Agent will execute and deliver any documents, instructions or instruments evidencing any permitted release of the Liens of the Collateral Agent on any Collateral. The Trustee and the Collateral Agent shall be entitled to receive an Opinion of Counsel and Officers’ Certificate in connection with any release of Liens evidencing compliance with the terms of this Indenture and the Security Documents.

(e) The fair value of Collateral released from the Liens created by this Indenture and the Security Documents pursuant to the terms of this Section 12.03 shall not be considered in determining whether the aggregate fair value of the Collateral released from the Liens created by this Indenture and the Security Documents in any calendar year exceeds the 10% threshold specified in Section 3.14(d)(1) of the TIA.

Section 12.04. Suits to Protect Collateral.

Subject to Sections 7.01 and 7.02 and the provisions of the Security Documents, the Trustee or Collateral Agent may, in its sole discretion and without the consent of the Holders, on behalf of the Holders, and shall at the direction of the Holders of a majority in aggregate principal amount of the then outstanding Notes, take all actions it deems necessary or appropriate in order to enforce any of the terms of the Security Documents and collect and receive any and all amounts payable in respect of the Note Obligations. Subject to the provisions of the Security Documents, each of the Trustee and Collateral Agent shall have power, exercised in its sole discretion and without the consent of the Holders, or at the direction of the Holders of a majority in aggregate principal amount of the then

-84-

outstanding Notes, to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts which may be unlawful or in violation of any of the Security Documents or this Indenture, and such suits and proceedings as the Trustee or Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Trustee or Collateral Agent and the Holders in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the Lien and security interest created by this Indenture and the Security Documents or be prejudicial to the interests of the Holders, the Trustee or the Collateral Agent).

Section 12.05. Powers Exercisable by Receiver, Trustee or Collateral Agent.

In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 12 and the Security Documents upon the Issuer and the Guarantors with respect to the release, sale or other disposition of such property may be exercised by such receiver, Trustee or the Collateral Agent, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Issuer or a Guarantor or of any Officer or Officers of the Issuer or a Guarantor required by the provisions of this Article 12.

Section 12.06. Determinations Relating to Collateral.

In the event (i) the Trustee or Collateral Agent shall receive any written request from the Issuer or any Guarantor under any Security Document for consent or approval with respect to any matter or thing relating to any Collateral or the Issuer’s or any Guarantor’s obligations with respect thereto, (ii) there shall be required from the Trustee or Collateral Agent under the provisions of any Security Document any performance or the delivery of any instrument or (iii) a Trust Officer of the Trustee or the Collateral Agent shall receive written notice of any nonperformance by the Issuer or any Guarantor of any covenant or any breach of any representation or warranty of the Issuer or any Guarantor set forth in any Security Document, and, in the case of clause (i), (ii) or (iii) above, the Trustee’s reasonably believes that the Trustee’s response or action is not otherwise specifically contemplated, or the Trustee does not have the discretion to undertake such response or action, hereunder or under the applicable Security Documents, then, in each such event, the Trustee or Collateral Agent shall, within 30 Business Days, advise the Holders, in writing and at the Issuer’s expense, of the matter or thing as to which consent has been requested or the performance or instrument required to be delivered or the nonperformance or breach of which the Trustee has received written notice. The Holders of not less than a majority in aggregate principal amount of the then outstanding Notes pursuant to Section 6.05 shall have the exclusive authority to direct the response of the Trustee or the Collateral Agent, as the case may be, to any of the circumstances contemplated in clauses (i), (ii) and (iii) above.

Section 12.07. Certificates of the Issuer and the Guarantors.

The Issuer will comply with the provisions of Section 314 of the TIA to the extent applicable. To the extent applicable, the Issuer will comply with Section 313(b) of the TIA, relating to reports, and Section 314(d) of the TIA, relating to the release of property or securities subject to the Lien of the Security Documents. Any certificate or opinion required by Section 314(d) of the TIA may be made by an officer or legal counsel, as applicable, of the Issuer except in cases where Section 314(d) of the TIA requires that such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert selected by or reasonably satisfactory to the Trustee. Notwithstanding anything to the contrary in this Section 12.07, the Issuer will not be required to comply with all or any portion of Section 314(d) of the TIA if it reasonably determines that under the terms of Section 314(d) of the TIA or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of Section 314(d) of the TIA is inapplicable to any release or series of releases of Collateral.

Without limiting the generality of the foregoing, certain no action letters issued by the SEC have permitted an indenture qualified under the TIA to contain provisions permitting the release of collateral from Liens under such indenture in the ordinary course of the issuer’s business without requiring the issuer to provide certificates and other documents under Section 314(d) of the TIA.

-85-

Section 12.08. Certificates of the Trustee as Collateral Agent.

In the event that the Issuer or any Guarantor wishes to obtain from the Collateral Agent the release of Collateral in accordance with this Indenture and the Security Documents and has delivered the certificates and documents required by this Indenture and the Security Documents, the Collateral Agent shall determine whether it has received all documentation required by Section 314(d) of the TIA in connection with such release based on the Opinion of Counsel delivered pursuant to Section 12.02. The Collateral Agent, however, shall have no duty to confirm the legality or validity of such documents, its sole duty being to certify that it has received such documentation which on their face conform to Section 314(d) of the TIA.

Section 12.09. Purchaser Protected.

No purchaser or grantee of any property or rights purporting to be released herefrom shall be bound to ascertain the authority of the Trustee or Collateral Agent to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority; nor shall any purchaser or grantee of any property or rights permitted by this Indenture to be sold or otherwise disposed of by the Issuer or any Guarantor be under any obligation to ascertain or inquire into the authority of the Issuer or such Guarantor to make such sale or other disposition.

Section 12.10. Collateral Termination.

The obligations of the Issuer and the Guarantors to maintain and grant Liens on Collateral securing the Note Obligations under this Indenture or the Security Documents (the “Collateral Obligations”) may, by written notice of such election given by the Issuer to the Collateral Agent and the Holders of Notes (a “Collateral Termination Notice”), be terminated if the Notes obtain an Investment Grade Rating. Upon delivery of a valid Collateral Termination Notice to the Trustee (as Collateral Agent), together with an Officers’ Certificate, the Issuer and the Guarantors shall be entitled to the release of all Liens on the Collateral securing the Note Obligations in accordance with Section 12.03. The termination of the Collateral Obligations in accordance with the foregoing is referred to as a “Collateral Termination.”

Section 12.11. Authorization of Actions to Be Taken by the Collateral Agent Under the Security Documents.

(a) U.S. Bank National Association is hereby appointed to act in its capacity as the Collateral Agent, as mortgage trustee under the Ship Mortgages, and as “Authorized Representative,” “Senior Class Debt Representative,” the “Senior Representative” and, if it becomes the “Major Additional Senior Representative” under the Intercreditor Agreement, the “Controlling Agent” of the Holders under the Intercreditor Agreement. Subject to the provisions of the Intercreditor Agreement and the applicable Security Documents:

(1) the Collateral Agent shall execute and deliver the Security Documents and act in accordance with the terms thereof;

(2) the Collateral Agent, as each Holder’s Senior Class Debt Representative under the Intercreditor Agreement, is entitled to, without further consent of the Trustee or the Holders: (A) appoint the Bank Collateral Agent (including any replacement thereof) as the “Controlling Agent” for purposes of the Intercreditor Agreement and the other “Collateral Documents” (as defined in the Intercreditor Agreement), (B) authorize the Controlling Agent to take such actions on its behalf and to exercise such powers as are delegated to the Controlling Agent in the Collateral Documents, together with such actions and powers as are reasonably incidental thereto, and (C) agree to take (or cause to be taken) such actions and not to take (or cause to be taken) such actions as the Controlling Agent may instruct with respect to the “Shared Collateral” (as defined in the Intercreditor Agreement) in accordance with, and subject to, the Intercreditor Agreement

(3) the Collateral Agent may, in its sole discretion and without the consent of the Trustee or the Holders, take all actions it deems necessary or appropriate in order to:

-86-

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

(B) collect and receive any and all amounts payable in respect of the Note Obligations of the Issuer and the Guarantors to the Holders, the Collateral Agent or the Trustee under this Indenture, the Notes, the Notes Guarantees and the Security Documents.

(b) The Trustee on behalf of itself and the Holders hereby appoints the Collateral Agent, as trustee to hold the Ship Mortgages, and the Collateral Agent hereby accepts such appointment and declares that it will hold the Ship Mortgages in trust under the terms set forth in the Ship Mortgages for the use and benefit of the Holders in accordance with and subject to all of the terms and conditions contained in this Agreement, the Security Documents and the Intercreditor Agreement, and agrees to perform the same and to receive, manage and disburse all monies at any time constituting part of the Collateral in accordance with the terms hereof and thereof. The Collateral Agent, in so receiving, managing, and disbursing such monies, shall exercise the same degree of care that is customarily used by similar institutions in similar circumstances.

(REVERSE OF SECURITY)

7.125% SENIOR SECURED NOTE DUE 2017

1. Interest. Hercules Offshore, Inc., a Delaware corporation (the “Issuer”), promises to pay interest on the principal amount of this Note at the rate per annum shown above. Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from April 3, 2012. The Issuer will pay interest semi-annually in arrears on each Interest Payment Date, commencing October 1, 2012. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Issuer shall pay interest on overdue principal and on overdue installments of interest (without regard to any applicable grace periods) to the extent lawful from time to time on demand at the rate then borne by the Notes.

2. Method of Payment. The Issuer shall pay interest on the Notes (except defaulted interest) to the Persons who are the registered Holders at the close of business on the March 15 or September 15 immediately preceding the Interest Payment Date (whether or not such day is a Business Day) even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Notes to a Paying Agent to collect payments of principal. Payments of principal and interest will be made in money of the United States that at the time of payment is legal tender for payment of public and private debts. If a Holder of Notes in certificated form has given wire transfer instructions to the Issuer at least ten Business Days prior to the applicable payment date, the Issuer will make all payments on such Holder’s Notes by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Paying Agent unless the Issuer elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders.

3. Paying Agent and Registrar. Initially, U.S. Bank National Association, a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Issuer may change any Paying Agent, Registrar or co-Registrar without notice to the Holders. Neither the Issuer nor any of its Affiliates may act as Paying Agent but may act as Registrar or co-Registrar. The Issuer has designated the Corporate Trust Office of the Trustee as its office where Notes may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands to or upon the Issuer in respect of the Notes may be served.

4. Indenture. The Issuer issued this Note under an Indenture, dated as of April 3, 2012 (the “Indenture”), by and among the Issuer, the Guarantors and the Trustee. This Note is one of a duly authorized issue of Initial Notes of the Issuer designated as its 7.125% Senior Secured Notes due 2017 (the “Notes”). The Notes include the Initial Notes and the Additional Notes, if any, issued pursuant to the Indenture. The Initial Notes and the Additional Notes are treated as a single class of securities under the Indenture. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of them. The Notes are general obligations of the Issuer. The Notes and the Note Guarantees are secured by first priority Liens (subject to Permitted Liens) in the Collateral, granted to the Trustee (as Collateral Agent) for the benefit of the Holders of the Notes, as provided in the Indenture and the Security Documents.

5. Redemption.

(a) Optional Redemption. The Notes will be redeemable, at the Issuer’s option, in whole at any time or in part from time to time, on and after April 1, 2014 at the following Redemption Prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on April 1 of the applicable year set forth below, plus, in each case, accrued and unpaid interest to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date):

A-4

Year		Percentage
2014			105.344	%
2015			102.672	%
2016 and thereafter			100.000	%

(b) Redemption at Applicable Premium. In addition, prior to April 1, 2014, the Issuer may redeem the Notes, at its option, in whole at any time or in part from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus the Applicable Premium as of, and accrued and unpaid interest to the applicable Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date).

(c) Redemption upon Consummation of Certain Qualified Equity Offerings. Notwithstanding the foregoing, at any time, or from time to time, prior to April 1, 2014, the Issuer may on any one or more occasions, at its option, use all or any portion of the net cash proceeds of one or more Qualified Equity Offerings to redeem Notes at a Redemption Price equal to 107.125% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date); provided that at least 65.0% of the aggregate principal amount of Notes originally issued on the Issue Date remains outstanding immediately after giving effect to any such redemption. In order to effect the foregoing redemption with the proceeds of any Qualified Equity Offering, the Issuer shall consummate such redemption not more than 180 days after the consummation of any such Qualified Equity Offering.

6. Notice of Redemption. Notice of redemption under paragraph 5 of this Note will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder to be redeemed at such Holder’s registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a satisfaction and discharge of the Indenture.

Except as set forth in the Indenture, if money for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for redemption on such redemption date, then, unless the Issuer defaults in the payment of such Redemption Price plus accrued interest, if any, the Notes called for redemption will cease to bear interest from and after such Redemption Date and the only right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued interest, if any.

7. Offers to Purchase. The Indenture provides that, in certain circumstances following an Asset Sale (as defined in the Indenture) and upon the occurrence of a Change of Control (as defined in the Indenture), and subject to further limitations contained therein, the Issuer will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture.

8. Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder shall register the transfer or exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption.

9. Persons Deemed Owners. The registered holder of a Note shall be treated as the owner of it for all purposes.

10. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Issuer. After that, Holders entitled to money must look to the Issuer for payment as general creditors unless an “abandoned property” law designates another Person.

A-5

11. Legal Defeasance and Covenant Defeasance. If the Issuer at any time deposits with the Trustee U.S. legal tender or U.S. Government Obligations sufficient to pay the principal of and interest on the Notes to redemption or the scheduled due dates and complies with the other provisions of the Indenture relating to Covenant Defeasance, the Issuer will be discharged from certain provisions of the Indenture and the Notes (including certain covenants, but excluding its obligation to pay the principal of and interest on the Notes). The Notes are also subject to Legal Defeasance as provided in Article 9 of the Indenture.

12. Amendments, Supplements, and Waivers. Subject to certain exceptions, the Indenture, the Security Documents or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, and any existing Default or Event of Default or noncompliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture, the Security Documents or the Notes to, among other things, cure any ambiguity, defect, omission, mistake or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes or make any other change that does not adversely affect in any material respect the rights of any Holder.

13. Restrictive Covenants. The Indenture imposes certain limitations on the ability of each of the Issuer and its Restricted Subsidiaries to, among other things, incur additional Indebtedness, make payments in respect of its Equity Interests, enter into transactions with Affiliates, create dividend or other payment restrictions affecting Restricted Subsidiaries, sell assets, create Liens, make certain Investments, merge or consolidate with any other Person, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of its assets. Such limitations are subject to a number of important qualifications and exceptions. The Issuer must annually report to the Trustee on compliance with such limitations.

14. Successor Entity. When a successor entity assumes, in accordance with the Indenture, all the obligations of its predecessor under the Notes, the Security Documents and the Indenture, and immediately before and thereafter no Default or Event of Default exists and certain other conditions are satisfied, the predecessor entity will be released from those obligations.

15. Defaults and Remedies. Events of Default are set forth in the Indenture. If an Event of Default (other than an Event of Default specified in Section 6.01(g) or (h)) shall occur and be continuing, the Trustee, by written notice to the Issuer, or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable (a) if there is no Indebtedness outstanding under any Senior Facility at such time, immediately and (b) if otherwise, according to the terms of the Intercreditor Agreement, unless a Collateral Termination has occurred, and if the Collateral Termination has occurred, upon the earlier of (x) the final maturity (after giving effect to any applicable grace period or extensions thereof) or an acceleration of any Indebtedness under any Credit Facility prior to the express final stated maturity thereof and (y) five Business Days after the Authorized Representative under each Credit Facility receives the acceleration declaration, but, in the case of this clause (b), only if such Event of Default is then continuing. No such rescission shall affect any subsequent Default or impair any right consequent thereto. If an Event of Default specified in Section 6.01(g) or (h) occurs with respect to the Issuer and is continuing, then, to the extent permitted by applicable law, all unpaid principal of and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

16. Trustee Dealings with the Issuer. The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer, and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

17. No Recourse Against Others. As more fully described in the Indenture, no director, officer, employee, stockholder or incorporator of the Issuer shall have any liability for any obligations of the Issuer under the Notes or this Indenture, or of any Guarantor under its Note Guarantees or the Security Documents or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes.

18. Authentication. This Note shall not be valid until the Trustee or Authenticating Agent manually signs the certificate of authentication on this Note.

We acknowledge that Hercules Offshore, Inc. and the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Restriction Termination Date of the applicable Notes pursuant to clause (c), (e) or (f) above to require the delivery of an opinion of counsel satisfactory to Hercules Offshore, Inc. and the Trustee.

4. We understand that the Trustee will not be required to accept for registration of transfer any Notes acquired by us, except upon presentation of evidence satisfactory to Hercules Offshore, Inc. and the Trustee that the foregoing restrictions on transfer have been complied with. We further understand that any Notes purchased by us in the form of definitive physical certificates will bear a legend reflecting the substance of paragraph 3 of this letter.
