Furthermore, in calculating Fixed Charges for purposes of determining the denominator (but not the numerator) of this “Fixed Charge Coverage Ratio”:

(2) notwithstanding clause (1) above, interest on Indebtedness determined on a fluctuating basis, to the extent such interest is covered by Interest Rate Agreements, shall be deemed to accrue at the rate per annum resulting after giving effect to the operation of such agreements; and

(3) the amount of Fixed Charges attributable to any Preferred Stock (other than Disqualified Stock) issued by the Parent that is mandatorily convertible or redeemable solely into common equity of the Parent within 365 days of the Transaction Date will be recalculated by multiplying (x) the actual amount of Fixed Charges attributable thereto for the Four Quarter Period by (y) a fraction, the numerator of which is the number of days from (and including) the Transaction Date to (but excluding) the applicable conversion or redemption date and the denominator of which is 365.

14

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note may be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures only upon certification that beneficial ownership interests in such Regulation S Temporary Global Notes are owned by either non-U.S. Persons or U.S. Persons who purchased such interests in a transaction that did not require registration under the Securities Act. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interests therein as hereinafter provided.

(d) Euroclear and Clearstream Procedures Applicable.   The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Note that are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

At least one Officer must sign the Notes for the Issuers by manual or facsimile signature.

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

A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee will, upon receipt of a written order of the Issuers signed by an Officer of the Issuers (an “ Authentication Order ”), authenticate Notes in an aggregate principal amount of $300,000,000 for original issue on the Issue Date. The Trustee shall authenticate additional Notes (“ Additional Notes ”) thereafter in unlimited aggregate principal amount for original issue upon receipt of an Authentication Order. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuers pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent acceptable to the Issuers to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Issuers.

Section 2.03 Registrar and Paying Agent.

The Issuers will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“ Registrar ”) and an office or agency where Notes may be presented for payment (“ Paying Agent ”) and an office or agency where notices and demands to or upon the Issuers, if any, in respect of the Notes and this Indenture may be served. The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without notice to any Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuers or any of their respective Subsidiaries may act as Paying Agent or Registrar.

37

The Issuers initially appoint The Depository Trust Company (“ DTC ”) to act as Depositary with respect to the Global Notes.

The Issuers initially appoint the Trustee to act as the Registrar, Paying Agent and Agent for service of notices and demands in connection with the Notes and this Indenture, and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

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

Section 2.05 Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Issuers will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes.

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE ‘‘SECURITIES ACT’’), OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.

No Opinion of Counsel shall be required to be delivered in connection with the mandatory exchange process under this clause (C) and the removal of the Private Placement Legend; provided , however , the Trustee may rely on an Officer’s Certificate from the Issuers as sufficient evidence of the existence and satisfaction of the conditions as described above.

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those paid under this Indenture, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

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

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

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

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will, upon receipt of an Authentication Order, authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.13 CUSIP or ISIN Numbers

The Issuers in issuing the Notes may use “CUSIP” or “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” or “ISIN” numbers in notices of redemption as a convenience to Holders; provided , that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuers will promptly notify the Trustee in writing of any change in the “CUSIP” or “ISIN” numbers.

ARTICLE 3

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

If the Issuers elect to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, no later than the delivery of notice to Holders thereof, the Issuers shall notify the Trustee in writing of the redemption date, the principal amount of Notes to be redeemed, the clause of this Indenture pursuant to which the redemption shall occur and the redemption price (identifying the Notes by CUSIP or ISIN, as applicable). At the Issuers’ written request delivered at least 5 Business Days prior to the applicable date of notice (unless a shorter period shall be acceptable to the Trustee), the Trustee shall deliver any notice pursuant to Section 3.07 as prepared by the Issuers, to each Holder of Notes to be redeemed in the Issuers’ names and at the Issuers’ expense. Notice given to the Trustee pursuant to this Section 3.01 may, at the Issuers’ discretion, state that any such redemption may be subject to the satisfaction of one or more conditions precedent.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed, the Trustee will select Notes for redemption or purchase on a pro rata basis (or, in the case of Notes issued in global form pursuant to Article 2 hereof, based on a method that most nearly approximates a pro rata selection as the Trustee deems fair and appropriate) unless otherwise required by law or applicable stock exchange or depositary requirements.

Upon selection, the Trustee will promptly notify the Issuers in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $200,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. No Notes of $2,000 or less can be redeemed in part.

Section 3.03 Notice of Redemption.

Notices of redemption will be mailed by first class mail (or delivered to DTC in the case of Global Notes) at least 30 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed at its registered address, except that redemption notices may be mailed (or delivered as the case may be) more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Article 8 or 11 hereof. Notice of any redemption of the Notes in connection with a corporate transaction (including an Equity Offering, an incurrence of Indebtedness or a Change of Control) may, at the Issuers’ discretion, be given prior to the completion thereof and any such redemption or notice may, at the Issuers’ discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related transaction. If such redemption or purchase is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuers’ discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption

52

date as so delayed. In addition, the Issuers may provide in such notice that payment of the redemption price and performance of the Issuers’ obligations with respect to such redemption may be performed by another Person.

If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest will be paid to the Person in whose name the Note is registered at the close of business on such record date, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the Issuers.

The notice will identify the Notes (by CUSIP or ISIN, if applicable) to be redeemed and will state:

(a) the redemption date;

(b) the redemption price;

(c) if any Note is to be redeemed in part only, the notice of redemption that relates to that Note will state the portion of the principal amount of that Note that is to be redeemed and that, after the redemption date upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder of Notes upon cancellation of the original Note;

(d) that, on and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption;

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

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

(g) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

(h) if such notice is conditioned upon the occurrence of one or more conditions precedent, the nature of such conditions precedent;

(i) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(j) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Issuers’ written request, the Trustee will give the notice of redemption in the Issuers’ names and at the Issuers’ expense; provided , however , that the Issuers have delivered to the Trustee, at least 30 days prior to the redemption date, an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

53

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is delivered in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, subject to the satisfaction of any conditions precedent contained in such notice of redemption.

Section 3.05 Deposit of Redemption or Purchase Price.

If the Issuers elect to redeem Notes in accordance with Section 3.07 hereof, one Business Day prior to the anticipated redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of accrued interest on all Notes to be redeemed or purchased on that date. Upon payment of any amount in connection with redemption, the Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of accrued interest on all Notes to be redeemed or purchased.

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

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Issuers will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

(h) in the case of an Asset Sale Offer, that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Trustee, after consultation with the Issuers, will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in denominations of $200,000, or an integral multiple of $1,000 in excess thereof, will be purchased); and

The Issuers, the Depositary or the Paying Agent, as the case may be, will promptly mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuers for purchase, and the Issuers will promptly issue a new Note, and the Trustee, upon written request from the Issuers, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered.

Section 3.10 Redemption for Changes in Taxes

The Issuers may redeem the Notes, in whole but not in part, at their discretion at any time upon giving not less than 30 nor more than 60 days’ notice to the Holders thereof (which notice shall be irrevocable and given in accordance with the procedures described under Section 3.02), at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest to, but not including, the date of redemption (a “ Tax Redemption Date ”) and all Additional Amounts (if any) then due and that will become due on the Tax Redemption Date as a result of the redemption or otherwise (subject to the right of Holders of the Notes on the relevant record date to receive interest due on the relevant interest payment date and Additional Amounts (if any) in respect thereof if the Notes have not been redeemed or repurchased prior to such date), if on the next date on which any amount would be payable in respect of the Notes, the Issuers or any Guarantor is or would be required to pay Additional Amounts, and the Issuers or such Guarantor (but, in the case of a Guarantor, only if the payment giving rise to such requirement cannot be made by the Issuers or another Guarantor without the obligation to pay Additional Amounts) cannot avoid any such payment obligation by taking commercially reasonable measures available to them (including, for the avoidance of doubt, the appointment of a new Paying Agent), and the requirement to pay such Additional Amounts arises as a result of:

(a) any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the relevant Tax Jurisdiction affecting taxation, which change or amendment has not been publicly announced before and becomes effective after the Issue Date (or, if the relevant Tax Jurisdiction became a Tax Jurisdiction on the Issue Date, such later date); or

(b) any change in, or amendment to, the existing official published position regarding the application, administration or interpretation of such laws, regulations or rulings (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), which change or amendment has not been publicly announced before and becomes effective after the Issue Date (or, if the relevant Tax Jurisdiction became a Tax Jurisdiction on a date after the Issue Date, such later date).

57

The Issuers will not give any such notice of redemption earlier than 60 days prior to the earliest date on which the Issuers or the applicable Guarantors would be obligated to make such payment or withholding if a payment in respect of the Notes were then due and at the time such notice is given, the obligation to pay Additional Amounts must remain in effect. Prior to the publication or, where relevant, delivery of any notice of redemption of the Notes pursuant to the foregoing, the Issuers will deliver to the trustee an opinion of independent tax counsel of recognized standing (which counsel shall be reasonably acceptable to the trustee) attesting to the effect that there has been such a change or amendment which would entitle the Issuers to redeem the Notes under this Indenture (which opinion, for the avoidance of doubt, shall not be required to include an opinion as to whether “commercially reasonable efforts” could be undertaken to avoid the otherwise applicable obligations). In addition, before the Issuers publish or mail notice of redemption of the Notes pursuant to the forgoing, they will deliver to the trustee an Officer’s Certificate to the effect that they cannot avoid the obligation to pay Additional Amounts by taking commercially reasonable measures available to them.

The Trustee will accept and shall be entitled to conclusively rely on such Officer’s Certificate and Opinion of Counsel as sufficient evidence of the existence and satisfaction of the conditions as described above, in which event it will be conclusive and binding on all of the Holders.

(2) in the event that an item of Indebtedness (or any portion thereof) meets the criteria of more than one of the types of Indebtedness described in Section 4.09, the Parent, in its sole discretion, will classify such item of Indebtedness (or any portion thereof) at the time of Incurrence and will only be required to include the amount and type of such Indebtedness in Section 4.09(a) or one of the clauses of Section 4.09(b) ( provided, that any Indebtedness originally classified as Incurred pursuant to any of clauses (2) through (22) of Section 4.09(b) may later be reclassified as having been Incurred pursuant to Section 4.09(a) or any other of clauses (2) through (22) of Section 4.09(b) to the extent that such reclassified Indebtedness could be Incurred pursuant to Section 4.09(a) or one of clauses (2) through (22) of Section 4.09(b), as the case may be, if it were Incurred at the time of such reclassification); and

(3) the Parent will be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in this Section 4.09.

69

(d) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided , that, if such Indebtedness is incurred to Refinance other Indebtedness denominated in a foreign currency, and such Refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such Refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Permitted Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being Refinanced (plus accrued interest and premium (including tender premium) thereon, any committed or undrawn amounts associated with, original issue discount on, and underwriting discounts, fees, commissions and expenses incurred in connection with, such Refinancing).

(e) 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 respective Indebtedness is denominated that is in effect on the date of such Refinancing.

(f) The Parent will not, and will not permit the Issuers or any other Guarantor to, directly or indirectly, incur any Indebtedness (including Permitted Debt) that is contractually subordinated or junior in right of payment to any Indebtedness of the Parent, the Issuers or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Notes or the applicable Note Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Parent, the Issuers or such Guarantor, as the case may be; provided , that (i) unsecured Indebtedness shall not be treated as subordinated or junior to any other Indebtedness merely because it is unsecured and (ii) Indebtedness shall not be treated as subordinated or junior in right of payment to other Indebtedness merely because such Indebtedness has a junior priority with respect to any collateral.

Section 4.10 Asset Sales.

(a) The Parent will not, and will not permit any of the Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Parent (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Sale) of the assets or shares of Capital Stock of a Restricted Subsidiary issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received by the Parent or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash consideration:

(A) any liabilities (as shown on the Parent’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of the Parent or any Restricted Subsidiary (other than liabilities that are by their terms contractually subordinated to the notes or any Note Guarantee) (i) that are assumed by the transferee of any such assets and for which the Parent or such Restricted Subsidiary, as the case may be, has been released or indemnified against further liability or (ii) in respect of which neither the Parent nor any Restricted Subsidiary following such Asset Sale has any obligation;

70

(B) any securities, notes or other obligations received by the Parent or any such Restricted Subsidiary from such transferee that are converted by the Parent or such Restricted Subsidiary within 365 days into cash or Cash Equivalents, to the extent of the cash or Cash Equivalents received in that conversion;

(C) any Designated Noncash Consideration having an aggregate Fair Market Value that, when taken together with all other Designated Noncash Consideration previously received and then outstanding, does not exceed at the time of the receipt of such Designated Noncash Consideration (with the Fair Market Value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value) the greater of $75.0 million or 2.0% of Total Assets; and

(D) any Investment, stock, asset, property or capital expenditure of the kind referred to in Section 4.10(b)(3).

(b) Within one year from the later of the date of an Asset Sale or the receipt of any Net Proceeds from an Asset Sale, the Parent or any Restricted Subsidiary may apply such Net Proceeds:

(1) to prepay, repay, redeem or purchase (a) Indebtedness and other Obligations that are secured by a Lien or (b) Indebtedness (other than any Disqualified Stock) and other Obligations of a Non-Guarantor Subsidiary (other than Indebtedness owed to the Parent or any Restricted Subsidiary), and, in each case, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2) to prepay, repay, redeem or purchase Senior Indebtedness of the Parent, the Issuers or any other Guarantor; provided, that, the Parent shall apply not less than a pro rata portion (determined and as modified based on the provisions set forth below) of such Net Proceeds to (y) redeem or repurchase the Notes (i) as described in Section 3.07 or (ii) through open market purchases at a purchase price not less than 100% of the principal amount thereof, plus accrued but unpaid interest thereon, or (z) make an offer (in accordance with the procedures set forth below) to all holders to purchase their Notes at a purchase price not less than 100% of the principal amount thereof, plus accrued but unpaid interest thereon to, but not including, the repurchase date (in each case other than Indebtedness or other Obligations owed to the Parent or an Affiliate of the Parent); or

(3) to make an Investment in any one or more businesses ( provided that, if such Investment is in the form of the acquisition of Capital Stock of a Person as a result of which such Person becomes a Subsidiary, such Person shall become a Restricted Subsidiary), to acquire assets or property (including the acquisition or license of intellectual property) or to make capital expenditures, in each case (a) constituting, or used or useful in a Permitted Business or (b) that replace the properties and assets that are the subject of such Asset Sale;

provided that, in the case of Section 4.10(b)(3), entering into and not abandoning or rejecting a binding commitment to make an Investment, acquire assets or property or make capital expenditures to satisfy Section 4.10(b)(3) above shall be treated as a permitted application of Net Proceeds from the date of such commitment; provided that (x) such Investment, acquisition or capital expenditure is consummated within 545 days after the later of the receipt of such Net Proceeds or the date of such Asset Sale and (y) if such

71

Investment, acquisition or capital expenditure is not consummated within the period set forth in subclause (x), or otherwise applied as set forth in Section 4.10(b) (1) or (2), the Net Proceeds not so applied will be deemed to constitute Excess Proceeds under Section 4.10(d).

(c) Pending the final application of any Net Proceeds, the Parent or a Restricted Subsidiary may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture.

(d) Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) will constitute “ Excess Proceeds .” When the aggregate amount of Excess Proceeds exceeds the greater of $75.0 million or 2.0% of Total Assets, within 30 days thereof, the Issuers will make an offer (an “ Asset Sale Offer ”) to all Holders of Notes and all Holders of other Senior Indebtedness containing provisions similar to those set forth in this Indenture with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets ( provided that the portion of such Asset Sale Offer made to the Holders of the Notes is not less than a pro rata portion of the Notes taken together with such other Senior Indebtedness) to purchase, prepay or redeem the maximum principal amount of Notes and such other Senior Indebtedness (plus all accrued interest on the Indebtedness and the amount of all fees and expenses, including premiums, incurred in connection therewith) that may be purchased, prepaid or redeemed out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount (or accreted value, if less, or such lesser amount as may be provided by the terms of such other Senior Indebtedness), plus accrued and unpaid interest to the date of purchase, prepayment or redemption (subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date if the Notes have not been redeemed or repurchased prior to such date), and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Parent or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other Senior Indebtedness tendered in (or required to be prepaid or redeemed in connection with) such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis, based on the amounts tendered or required to be prepaid or redeemed (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in denominations of $200,000, or an integral multiple of $1,000 in excess thereof, will be purchased) unless otherwise required by law or applicable depositary requirements. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

Section 4.11 Transactions with Affiliates.

(a) The Parent will not, and will not permit any of the Restricted Subsidiaries to, make any payment to or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, or advance with or guarantee for the benefit of, any Affiliate of the Parent (each, an “ Affiliate Transaction ”) involving aggregate payments or consideration in excess of $7.5 million, unless:

(1) the Affiliate Transaction is on terms that are not materially less favorable to the Parent or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Parent or such Restricted Subsidiary with an unrelated Person; and

(2) the Parent delivers to the trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $45.0 million, a resolution adopted by the Board of Directors of the Parent approving such

Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction has been approved by a majority of the Board of Directors of the Parent and complies with Section 4.11(a)(1).

(b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to Section 4.11(a):

(2) transactions between or among the Parent and/or the Restricted Subsidiaries;

(3) transactions with any Person that is an Affiliate of the Parent solely because the Parent owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(8) any agreement as in effect on the Issue Date and described in the Offering Memorandum (or described in a document incorporated by reference in the Offering Memorandum as of the Issue Date) or any renewals or extensions of any such agreement (so long as such renewals or extensions are not less favorable in any material respect to the Parent or the Restricted Subsidiaries) and the transactions evidenced thereby;

(9) transactions in which the Parent or any Restricted Subsidiary, as the case may be, delivers to the trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction meets the requirements of Section 4.11(a)(1);

(10) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are fair to the Parent and the Restricted Subsidiaries, in the reasonable determination of the Board of Directors of the Parent or the senior management

73

(11) transactions in the ordinary course with (a) Unrestricted Subsidiaries or (b) joint ventures in which the Parent or a Subsidiary of the Parent holds or acquires an ownership interest (whether by way of Capital Stock or otherwise) so long as the terms of any such transactions are no less favorable to the Parent or any Subsidiary participating in such joint ventures than they are to other joint venture partners;

(12) the existence of, or the performance by the Parent or any of the Restricted Subsidiaries of its obligations under the terms of, any limited liability company agreement, limited partnership or other organizational documents or stockholders agreement (including any purchase agreement related thereto) to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter; provided , however, that the existence of, or the performance by the Parent or any Restricted Subsidiary of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after such date shall only be permitted by this clause (12) to the extent that the terms of any such amendment or new agreement, taken as a whole, is no less favorable to the Parent and the Restricted Subsidiaries than the agreement in effect on the Issue Date (as determined by the Board of Directors of the Parent or the senior management thereof in good faith);

(13) the provision of services to directors or officers of the Parent, any of the Restricted Subsidiaries or any of the Parent’s direct or indirect parent companies of the nature provided by the Parent or any of the Restricted Subsidiaries to customers in the ordinary course of business;

Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

Section 4.13 Corporate Existence.

Subject to Articles 5 and 10 (as applicable), each of the Issuers and the Guarantors will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate or other existence and rights (charter and statutory); provided , however , that the Issuers and the Guarantors shall not be required to preserve any such right if the Issuers or the Guarantors, as applicable, shall in good faith determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuers or the Guarantors, taken as a whole.

Section 4.14 Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, unless the Issuers have previously or concurrently delivered a redemption notice with respect to all the outstanding Notes pursuant to Section 3.07, within 30 days following such Change of Control, the Issuers will make an Offer to Purchase all of the Notes (a “Change of Control Offer”) on the terms set forth in this Indenture and in compliance with Section 3.09. In the Change of Control Offer, the Issuers will offer to purchase all of the Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest on the Notes repurchased to, but not including, the date of purchase (subject to the rights of holders of Notes on the relevant record date to receive interest due on the relevant interest payment date if the Notes have not been redeemed or repurchased prior to such date) (the “ Change of Control Payment ”).

(b) Notwithstanding anything to the contrary in this Section 4.14, the Issuers will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 under this Indenture, unless and until there is a default in payment of the applicable redemption price.

Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, or conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

Section 4.16 Reserved.

Section 4.17 Reserved.

Section 4.18 Additional Note Guarantees.

If any direct or indirect Restricted Subsidiary of the Parent that is not a Guarantor (other than an Immaterial Subsidiary or an Issuer) becomes a guarantor or obligor in respect of any Triggering Indebtedness, within 60 days of such event the Parent will, subject to applicable law, cause such Restricted Subsidiary to enter into a supplemental indenture pursuant to which such Subsidiary shall agree to Guarantee the Issuers’ Obligations under the Notes, fully and unconditionally and on a senior basis, subject to Section 10.02. The Parent also may, at any time, cause a Subsidiary to become a Guarantor by executing and delivering a supplemental indenture providing for the Guarantee of payment of the Notes by such Subsidiary on the basis provided in this Indenture. Any such supplemental indenture may be in the form of such supplemental indenture attached as Exhibit E hereto or such other form as

75

agreed between the Issuers, the applicable Guarantor and the Trustee; provided that such supplemental indenture shall include any Applicable Guarantee Limitations (in addition to any such Applicable Guarantee Limitations set forth in Article 10 hereof) to the extent the Issuers have delivered to the Trustee an Officer’s Certificate certifying that it has been advised by counsel in the applicable jurisdiction of the Guarantor as to necessity of such Applicable Guarantee Limitations. For the avoidance of doubt, no Opinion of Counsel shall be required to be delivered in respect of the necessity of any Applicable Guarantee Limitations and any Opinion of Counsel delivered in connection with such supplemental indenture pursuant to Section 9.05 may rely on such Officer’s Certificate as to the necessity of such Applicable Guarantee Limitations.

If any Guarantor becomes an Immaterial Subsidiary, the Parent shall have the right, by execution and delivery of a supplemental indenture to the Trustee, to cause such Immaterial Subsidiary to cease to be a Guarantor, subject to the requirement described in the first paragraph above that such Subsidiary shall be required to become a Guarantor if it ceases to be an Immaterial Subsidiary (except that if such Subsidiary has been properly designated as an Unrestricted Subsidiary it shall not be so required to become a Guarantor or execute a supplemental indenture); provided, further , that such Immaterial Subsidiary shall not be permitted to Guarantee the Credit Agreement or other Triggering Indebtedness of any Guarantor or the Issuers, unless it again becomes a Guarantor.

Section 4.19 Designation of Restricted and Unrestricted Subsidiaries.

The Parent may designate after the Issue Date any Subsidiary (other than the Issuers) (including any newly acquired or newly formed Subsidiary) as an “Unrestricted Subsidiary” under this Indenture (a “ Designation ”) only if:

(a) no Default or Event of Default has occurred and is continuing after giving effect to such Designation;

(b) the Subsidiary to be so designated and its Subsidiaries do not at the time of Designation own any Capital Stock or Indebtedness of, or own or hold any Lien on any Property of, the Parent or any other Subsidiary of the Parent that is not a Subsidiary of the Subsidiary so designated;

(c) the Subsidiary to be so designated and its Subsidiaries do not at the time of Designation have and do not thereafter Incur any Indebtedness pursuant to which the lender or other Holder of such Indebtedness has recourse to any of the assets of the Parent or any of the Restricted Subsidiaries; and

(d) either (x) the Subsidiary to be so designated has total consolidated assets of $1,000 or less or (y) if such Subsidiary has consolidated assets greater than $1,000, then the Parent could make a Restricted Payment at the time of such Designation in an amount equal to the Fair Market Value of all outstanding Investments owned by the Parent and the Restricted Subsidiaries in such Subsidiary under Section 4.07 and such amount is thereafter treated as an “Investment” for purposes of calculating the amount of Restricted Payments thereunder.

The Parent may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a “ Revocation ”) only if, immediately after giving effect such Revocation:

(e) (x) the Parent could Incur at least $1.00 of additional Indebtedness under Section 4.09(a) or (y) the Fixed Charge Coverage Ratio would not be less than immediately prior to such Revocation, in each case on a pro forma basis taking into account such Revocation;

76

(f) all Liens of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if Incurred at such time, have been permitted to be Incurred for all purposes of this Indenture; and

(g) no Default or Event of Default has occurred and is continuing after giving effect to such Revocation.

Each Designation and Revocation must be evidenced by promptly delivering to the Trustee a board resolution of the Board of Directors of the Parent giving effect to such Designation or Revocation, as the case may be, and an Officer’s Certificate certifying compliance with the preceding provisions. A Revocation will be deemed to be an Incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary.

Section 4.20 Suspension of Covenants When Notes Rated Investment Grade

(a) If on any date following the Issue Date, the Notes are rated Baa3 or better by Moody’s and BBB- or better by S&P (“ Investment Grade Status ”) (or, if either such entity ceases to rate such notes for reasons outside of the control of the Parent, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by the Parent as a replacement agency) then, beginning on that day and continuing until the Reversion Date (as defined below), the Parent and the Restricted Subsidiaries will not be subject to Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.18 and 4.19 and clause (a)(4) of Section 5.01 of this Indenture (collectively, the “ Suspended Covenants ”).

(b) If any time the Notes cease to have such Investment Grade Status, then the Suspended Covenants will thereafter be reinstated as if such covenants had never been suspended (the “ Reversion Date ”) and be applicable pursuant to the terms of this Indenture (including in connection with performing any calculation or assessment to determine compliance with the terms of this Indenture), unless and until the Notes subsequently attain Investment Grade Status (in which event the Suspended Covenants shall no longer be in effect for such time that the Notes maintain an Investment Grade Status); provided , however , that no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the Notes or the Note Guarantees with respect to the Suspended Covenants based on, and none of the Parent or any of its Subsidiaries shall bear any liability for, any actions taken or events occurring during the Suspension Period (as defined below), or any actions taken at any time pursuant to any contractual obligation arising prior to the Reversion Date, regardless of whether such actions or events would have been permitted if the applicable Suspended Covenants remained in effect during such period. The period of time between the date of suspension of the covenants and the Reversion Date is referred to as the “ Suspension Period .”

(c) On the Reversion Date, all Indebtedness Incurred during the Suspension Period will be classified to have been Incurred pursuant to Section 4.09(a) (to the extent such Indebtedness would be permitted to be Incurred thereunder as of the Reversion Date and after giving effect to the Indebtedness Incurred prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness would not be so permitted to be incurred pursuant to Section 4.09(a), such Indebtedness will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under clause (4) of Section 4.09(b). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.07 will be made as though Section 4.07 had been in effect since the Issue Date and throughout the Suspension Period; provided that, no Subsidiaries may be designated as Unrestricted Subsidiaries during the Suspension Period, unless such designation would have complied with Section 4.07 as if such covenant would have been in effect during such period. Accordingly, Restricted Payments made during the Suspension Period will reduce the amount available to be made as

77

Restricted Payments under Section 4.07(a). During the Suspension Period, any future obligation to grant further Note Guarantees shall be suspended. All such further obligation to grant Note Guarantees shall be reinstated upon the Reversion Date.

(d) The Trustee shall have no duty to monitor the ratings of the Notes, shall not be deemed to have any knowledge of the ratings of the Notes and shall have no duty to notify Holders if the Notes achieve Investment Grade Status or of the occurrence of a Reversion Date. The Issuers shall provide written notice to the Trustee of the commencement or end, as applicable, of a Suspension Period.

Section 4.21 Additional Amounts

All payments made by or on behalf of the Issuers or any of the Guarantors under or with respect to the Notes or any Note Guarantee will be made without withholding or deduction for, or on account of, any present or future Taxes unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes imposed or levied by or on behalf of (1) any jurisdiction in which the Issuers or any Guarantor (including any successor entity) is then incorporated, organized, engaged in business or resident for tax purposes or any political subdivision or Governmental Authority thereof or therein or (2) any jurisdiction from or through which payment is made by or on behalf of the Issuers or any Guarantor (including, without limitation, the jurisdiction of any Paying Agent) or any political subdivision or Governmental Authority thereof or therein (each of (1) and (2), a “ Tax Jurisdiction ”) will at any time be required to be made from any payments under or with respect to the Notes or any Note Guarantee, including, without limitation, payments of principal, redemption price, purchase price, interest or premium, the Issuers or the relevant Guarantor, as applicable, will pay such additional amounts (the “ Additional Amounts ”) as may be necessary in order that the net amounts received and retained in respect of such payments by each beneficial owner of Notes after such withholding or deduction by any applicable withholding agent will equal the amounts that would have been received and retained in respect of such payments in the absence of such withholding or deduction; provided, however , that no Additional Amounts will be payable with respect to:

(a) any Taxes, to the extent such Taxes would not have been imposed but for the Holder or the beneficial owner of the Notes being a citizen or resident or national of, being incorporated in or having any other present or former connection with the relevant Tax Jurisdiction other than the acquisition or holding of any Note, the exercise or enforcement of rights under any Note or this Indenture or any Note Guarantee or the receipt of any payment in respect of any Note or Note Guarantee;

(b) any Taxes, to the extent such Taxes were imposed as a result of the presentation of a Note for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented on the last day of such 30 day period);

(c) any estate, inheritance, gift, sale, transfer or similar Taxes;

(d) any Taxes required to be withheld or deducted as a result of the presentation of any Note for payment (where presentation is required) by or on behalf of a Holder of Notes who would have been able to avoid such withholding or deduction by presenting the relevant Note to another Paying Agent designated by the Issuers under this Indenture;

(e) any Taxes required to be paid other than by deduction or withholding from payments under, or with respect to, the Notes or any Note Guarantee;

78

(f) any Taxes to the extent such Taxes are imposed or withheld by reason of the failure of the Holder or beneficial owner of Notes, following the Issuers’ reasonable written request addressed to the Holder or beneficial owner at least 60 days before any such withholding or deduction would be payable, to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or administrative practice of a Tax Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Tax Jurisdiction, but in each case, only to the extent the Holder or beneficial owner is legally eligible to comply with such requirements;

(g) any Taxes imposed or withheld by reason of the failure of the Holder or beneficial owner of the Notes to comply with the requirements of Sections 1471 through 1474 of the Code, as of the Issue Date (or any amended or successor version that is substantively comparable and not materially more onerous to comply with), the U.S. Treasury Regulations issued thereunder or any official interpretation thereof or any agreement entered into pursuant to Section 1471(b) of the Code, as of the Issue Date (or any amended or successor provision described above);

(h) any withholding Tax imposed by the United States or a political subdivision thereof;

(i) any Taxes imposed on or with respect to any payment by the Issuers or any Guarantor to the Holder if such Holder is a fiduciary, partnership, limited liability company or person other than the sole beneficial owner of such payment to the extent that such Taxes would not have been imposed had such Holder been the sole beneficial owner of the applicable Notes;

(j) any Taxes withheld in Luxembourg, deducted or imposed on a payment to an individual and that are required to be made pursuant to the law of 23 December 2005 introducing a final withholding tax on saving income in favor of beneficiaries who are individuals resident in Luxembourg; or

(k) any combination of clauses (a) through (j) above.

In addition to the foregoing, the Issuers and the Guarantors will also pay and indemnify the Holder for any present or future stamp, issue, registration, value added, transfer, court or documentary Taxes, or any other excise or property Taxes, charges or similar levies (including penalties, interest and any other liabilities related thereto) which are levied by any Tax Jurisdiction on the execution, delivery, issuance, or registration of any of the Notes, this Indenture, any Note Guarantee or any other document referred to therein, or the receipt of any payments with respect thereto, or the enforcement of any Note or Note Guarantee.

If the Issuers or any Guarantor, as the case may be, becomes aware that it will be obligated to pay Additional Amounts with respect to any payment under or with respect to the Notes or any Note Guarantee, the Issuers or the relevant Guarantor, as the case may be, will deliver to the Trustee on a date that is at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 30th day prior to that payment date, in which case the Issuers or the relevant Guarantor shall notify the Trustee promptly thereafter) an Officer’s Certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable. The Officer’s Certificate must also set forth any other information reasonably necessary to enable the Paying Agents to pay Additional Amounts on the relevant payment date. The Trustee shall be entitled to rely on an Officer’s Certificate as conclusive proof that such payments are necessary. The Issuers or the relevant Guarantor will provide the Trustee with documentation reasonably satisfactory to the Trustee evidencing the payment of Additional Amounts.

The Issuers or the relevant Guarantor will make all withholdings and deductions (within the time period and in the minimum amount) required by law and will remit the full amount deducted or withheld to the relevant Tax authority in accordance with applicable law. The Issuers or the relevant Guarantor will use its reasonable efforts to obtain Tax receipts from each Tax authority evidencing the payment of any Taxes so deducted or withheld. Upon request, the Issuers or the relevant Guarantor will furnish to the Trustee (or to a Holder upon request), within 60 days after the date the payment of any Taxes so deducted or withheld is made, certified copies of Tax receipts evidencing payment by the Issuers or such Guarantor, as the case may be, or if, notwithstanding such entity’s efforts to obtain receipts, receipts are not obtained, other evidence of payments (reasonably satisfactory to the Trustee) by such entity.

Whenever in this Indenture or the Notes there is mentioned, in any context, the payment of amounts based upon the principal amount of the Notes or of principal, interest or of any other amount payable under, or with respect to, any of the Notes or any Note Guarantee, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The above obligations will survive any termination, defeasance or discharge of this Indenture and any transfer by a Holder or Beneficial Owner of its Notes, and will apply, mutatis mutandis, to any jurisdiction in which any successor Person to the Issuers or any Guarantor is incorporated, organized, engaged in business or resident for tax purposes, any jurisdiction from or through which payment is made by or on behalf of such Person, and, in each case, any political subdivision or governmental authority thereof or therein.

(3) failure by the Parent or any of the Restricted Subsidiaries to comply with any of the other agreements in this Indenture (other than a failure that is the subject of clause (1) or (2)) for 60 days after receipt by the Parent of written notice of such failure from the Trustee (or receipt by the Parent and the Trustee of written notice of such failure from the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class);

(4) one or more defaults shall have occurred under any of the agreements, indentures or instruments under which the Parent, any Issuer or any Significant Subsidiary has outstanding Indebtedness in excess of $50.0 million, individually or in the aggregate, and either (a) such default results from the failure to pay such Indebtedness at its stated final maturity and such default has not been cured or the Indebtedness repaid in full within 60 days of the default or (b) such default or defaults have resulted in the acceleration of the maturity of such Indebtedness and such acceleration has not been rescinded or such Indebtedness repaid in full within 60 days of the acceleration;

(5) one or more final and nonappealable judgments or orders that exceed $50.0 million in the aggregate (net of amounts covered by insurance or bonded) for the payment of money have been entered by a court or courts of competent jurisdiction against the Parent, any Issuer or any Significant Subsidiary and such judgment or judgments are not satisfied, stayed, annulled or rescinded for 60 days;

(6) any Note Guarantee by the Parent or a Significant Subsidiary shall for any reason cease to be, or shall for any reason be held in any judicial proceeding not to be, or asserted in writing by the Parent or such Significant Subsidiary not to be, in full force and effect and enforceable in accordance with its terms, except to the extent contemplated by this Indenture and any such Note Guarantee, and any such default continues for 10 days;

(7) the Parent, any Issuer or any Significant Subsidiary:

(A) commences a voluntary insolvency proceeding,

82

(B) consents to the entry of an order for relief against it in an involuntary insolvency proceeding,

(C) consents to the appointment of a Bankruptcy Custodian of it or for all or substantially all of its property, or

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

provided, however , that the liquidation of any Restricted Subsidiary into another Restricted Subsidiary, other than as part of a credit reorganization, shall not constitute an Event of Default under this Section 6.01(7); and

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

(A) is for relief against the Parent, any Issuer or any Significant Subsidiary in an involuntary insolvency proceeding;

(C) orders the liquidation of the Parent, the Issuers or any Significant Subsidiary;

and the order or decree remains unstayed and in effect for 90 consecutive days.

Section 6.02 Acceleration.

If there is a continuing Event of Default (other than an Event of Default specified in Sections 6.01(7) and 6.01(8) hereof with respect to the Parent or the Issuer) with respect to the Notes, either the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes may declare the principal amount of all of the Notes to be due and payable immediately. However, at any time after the Trustee or the Holders, as the case may be, declare an acceleration with respect to the Notes, but before the applicable person has obtained a judgment or decree based on such acceleration, the Holders of a majority in principal amount of the outstanding notes may, under certain conditions, cancel such acceleration if the Parent has cured all Events of Default (other than the nonpayment of accelerated principal) with respect to the Notes or all such Events of Default have been waived as provided in this Indenture. If an Event of Default specified in Sections 6.01(7) and 6.01(8) hereof with respect to the Parent or any Issuer occurs, all outstanding Notes shall become due and payable without any further action or notice.

Notwithstanding the foregoing, to the extent the Issuers elect, the sole remedy for an Event of Default relating to the Parent’s failure to comply with the obligations as set forth under Section 4.03, will for the first 270 days after the occurrence of such an Event of Default, consist exclusively of the right to receive additional interest on the Notes (1) at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 90 days after the occurrence of such an Event of Default during which such event of default is continuing and (2) at a rate equal to 0.50% per annum of the principal amount of the Notes outstanding from the 91st day until the 270th day following the occurrence

83

of such event of default during which such event of default is continuing. If the Issuers so elect, such additional interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 270th day after the occurrence of the Event of Default (if the Event of Default relating to the reporting obligations is not cured or waived prior to such 270th day), the Notes will be subject to acceleration as provided above. The provisions of this Indenture described in this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any other Event of Default. In the event the Issuers do not elect to pay the additional interest following an Event of Default in accordance with this paragraph and the immediately following paragraph (or the Issuers elect to make such payment but does not pay the additional interest when due), the Notes will be subject to acceleration as provided above. In no event shall additional interest payable pursuant to the foregoing election accrue at a rate per year in excess of 0.50% per annum, regardless of the number of events or circumstances giving rise to requirements to pay such additional interest pursuant to this paragraph.

In order to elect to pay the additional interest in the immediately preceding paragraph as the sole remedy during the first 270 days after the occurrence of an Event of Default relating to the Parent’s failure to comply with the obligations as set forth under Section 4.03, the Issuers must notify all Holders, the Trustee and the Paying Agent (if other than the Trustee) in writing of such election prior to the beginning of such 270-day period. Upon the Issuers’ failure to timely give such notice, the Notes will be immediately subject to acceleration as provided in the first paragraph of this Section 6.02.

Section 6.03 Other Remedies.

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

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note 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. All remedies are cumulative to the extent permitted by law.

Subject to the duties of the Trustee to act with the required standard of care, if there is a continuing Event of Default, the Trustee need not exercise any of its rights or powers under this Indenture at the written request or direction of any of the Holders of Notes, unless such Holders have offered to the Trustee security or indemnity satisfactory to the Trustee. Subject to such provisions for security or indemnification of the Trustee and certain other conditions, the Holders of a majority in principal amount of the outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power the Trustee holds with respect to the Notes.

Section 6.04 Waiver of Past Defaults

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of principal of, premium on, if any, or interest on, the Notes; provided, however , that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. 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 impair any right consequent thereon.

84

Section 6.05 Control by Majority.

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability.

Section 6.06 Limitation on Suits.

No Holder of any Note will have any right to institute any proceeding with respect to this Indenture or for any remedy unless:

(a) the Trustee has failed to institute such proceeding for 60 days after the Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes;

(b) the Holders of at least 25% in principal amount of the then outstanding Notes have made a written request to the trustee, and offered indemnity or security satisfactory to the Trustee, to institute such proceeding as trustee; and

(c) the Trustee has not received from the Holders of a majority in principal amount of the outstanding Notes a direction inconsistent with such request.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the Holder of any Note will have an absolute and unconditional right to institute suit for the enforcement of any payment of the principal of, and any premium on, if any, or interest on such Note, on or after the date or dates they are to be paid as expressed in such Note.

Section 6.08 Collection Suit by Trustee.

If an Event of Default in payment of principal, premium or interest specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company (or any other obligor on the Notes) for the whole amount of unpaid principal and accrued interest remaining unpaid.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation (as agreed in writing by the Issuers and the Trustee), expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the

85

compensation(as agreed in writing by the Issuers and the Trustee), expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under this Indenture. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under this Indenture out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First : to the Trustee, its agents and attorneys for amounts due under this Indenture, including payment of all compensation, expenses and liabilities incurred (including attorney’s fees), and all advances made, by the Trustee and the costs and expenses of collection;

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

Third : to the Issuers or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

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

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.09 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will deliver a notice of its succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided, all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee. The Trustee shall have no responsibility for any action or inaction of any successor Trustee.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may at any time elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to the Indenture and all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “ Legal Defeasance ”). For this purpose, Legal Defeasance means that the Issuers and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium on, if any, or interest on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(b) the Issuers’ obligations with respect to the Notes under Sections 2.06, 2.07, 2.10 and 4.02 hereof;

(c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ and the Guarantors’ obligations in connection therewith; and

(d) this Article 8.

Subject to compliance with this Article 8, the Issuers may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

91

Section 8.03 Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 3.09, 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.18 and 4.19 hereof and clauses (a)(3) and (a)(4) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “ Covenant Defeasance ”), and the Notes will 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 will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the Indenture and outstanding Notes and Note Guarantees, the Issuers and the Guarantors may omit to comply with and will 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 will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3), (4), (5), (6), (7) (only as such clause 7 applies to Significant Subsidiaries) and (8) (only as such clause 8 applies to Significant Subsidiaries) hereof will not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

(a) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, premium on, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuers must specify whether such Notes are being defeased to such stated date for payment or to a particular redemption date;

(b) in the case of an election of Legal Defeasance under Section 8.02 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions:

(1) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling; or

(2) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

92

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such 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;

(c) in the case of an election of Covenant Defeasance under Section 8.03 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of the outstanding notes 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;

(d) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness), and the granting of Liens to secure such borrowings);

(e) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuers or any of the Guarantors is a party or by which the Issuers or any of the Guarantors is bound;

(f) the Issuers must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders of notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuers or others; and

(g) the Issuers must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions), each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Notwithstanding the foregoing provisions of this Section 8.04, the conditions set forth in the foregoing subsections (b), (c), (d), (e), (f) and (g) of this Section 8.04 need not be satisfied so long as, at the time the Issuers make the deposit described in subsection (a), (i) no Default under Section 6.01(1), (2), (7) and (8) has occurred and is continuing on the date of such deposit and after giving effect thereto and (ii) all Notes not previously delivered to the Trustee for cancellation (x) have become due and payable, (y) will become due and payable at their Stated Maturity within one year or (z) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer. If the conditions in the preceding sentence are satisfied, the Issuers shall be deemed to have exercised their Covenant Defeasance option.

Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “ Trustee ”) pursuant to Section 8.04 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this

93

Indenture, to the payment, either directly or through any Paying Agent (including the Issuers acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the written request of the Issuers any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Issuers.

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

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however , that, if the Issuers makes any payment of principal of, premium on, if any, or interest on, any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

Notwithstanding Section 9.02, without the consent of any Holder of Notes, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or the Note Guarantees:

(a) to cure any ambiguity, defect or inconsistency;

(e) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act of 1939, as amended;

(f) to conform the text of this Indenture, the Notes or the Note Guarantees to any provision of the “Description of the Notes” section of the Offering Memorandum, to the extent that the Trustee has received an Officer’s Certificate to the effect that such text constitutes an unintended conflict with the description of the corresponding provision in that “Description of the Notes;”

(g) to provide for the issuance of Additional Notes in accordance with the limitations set forth in this Indenture as of the Issue Date;

(h) to evidence and provide for the acceptance of appointment under this Indenture by a successor Trustee;

(i) to release any Guarantor in accordance with the terms of this Indenture;

(j) to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes;

(k) to add additional co-issuers (to the extent such entities are organized under the laws of the United States, any state of the United States or the District of Columbia, Luxembourg, Bermuda or Ireland) with respect to the Notes in accordance with the limitations set forth in this Indenture; or

(l) make any amendment to the provisions of Section 2.06 relating to the transfer and legending of Notes as permitted by this Indenture, including to facilitate the issuance and administration of Notes; provided , however, that such amendment does not adversely affect the rights of Holders to transfer Notes in any material respect.

Upon the request of the Issuers, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, each of this Indenture, the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, additional notes,

95

if any) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium on, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes).

Upon the request of the Issuers, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee will join with the Issuers and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental indenture.

It is not necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuers will promptly deliver to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to deliver such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Issuers or any Guarantor with any provision of this Indenture, the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(b) reduce the principal of or change the fixed maturity of any note or alter or waive any of the provisions with respect to the payment of Additional Amounts or the redemption of the Notes (except those provisions relating to Sections 4.10 and 4.14 hereof);

(c) reduce the rate of or change the time for payment of interest, including default interest, on any Note;

(d) waive a Default or Event of Default in the payment of principal of, premium on, if any, or interest on, the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted from such acceleration);

(e) make any Note payable in money other than that stated in the Notes;

96

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

(g) waive a redemption payment with respect to any Note (other than a payment required by Sections 4.10 or 4.14 hereof);

(h) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(i) make any change in the preceding amendment and waiver provisions.

Section 9.03 Revocation and Effect of Consents.

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

Section 9.04 Notation on or Exchange of Notes.

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

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

Section 9.05 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuers may not sign an amended or supplemental indenture until the Board of Directors of the Issuers approves it. In executing any amended or supplemental indenture, the Trustee will receive and (subject to Section 7.01 hereof) will be fully protected in conclusively relying upon, in addition to the documents required by Section 12.03 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and that such supplemental indenture constitutes the valid and binding obligation of the Issuers and any Guarantors party thereto, enforceable against such parties in accordance with its terms, subject to customary exceptions.

97

ARTICLE 10

NOTE GUARANTEES

Section 10.01 Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

(1) the principal of, premium on, if any, and interest on, the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and interest on, the Notes, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are 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 of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

98

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal state law or similar foreign law to the extent applicable to any Note Guarantee or unlawful financial assistance within the meaning of Section 82 of the Irish Companies Act 2014 (as amended). To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance under federal, state or similar foreign law or unlawful financial assistance within the meaning of Section 82 of the Irish Companies Act 2014 (as amended).

Section 10.03 Issuance and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees that this Indenture (or, a supplemental indenture to this Indenture) shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

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

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. Upon execution of a supplemental indenture to this Indenture by any Guarantor in the form of Exhibit E hereto, the Note Guarantee set forth in this Indenture and such supplemental indenture shall be deemed duly delivered, without any further action by any Person, on behalf of such Guarantor. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05 hereof, no Guarantor (other than the Parent, which is governed by Section 5.01) may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Parent, the Issuers or another Guarantor, unless either:

(a) subject to Section 10.05 hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger (the “Successor Guarantor”) unconditionally assumes all the obligations of that Guarantor under its Note Guarantees and this Indenture on the terms set forth herein or therein, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee; or

(b) the Note Guarantee of such Guarantor shall be released in accordance with Section 10.05 upon, or in connection with, such sale, disposition, consolidation or merger.

99

In case of any such consolidation, merger, sale or disposition and upon the assumption by the Successor Guarantor, by a supplemental indenture, of the Note Guarantees and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such Successor Guarantor will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Parent, the Issuers or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Parent or another Guarantor.

This Section 10.04 will not apply to the Merger. Notwithstanding anything to the contrary above, in the event the Acquisition does not occur, the Merger shall immediately be consummated without regard to any of the provisions described above.

Section 10.05 Releases.

Any Guarantor will be automatically and unconditionally released from all obligations under its Note Guarantee, and such Note Guarantee shall thereupon terminate and be discharged and of no further force and effect:

(a) concurrently with any sale, exchange, disposition or transfer (by merger or otherwise) of any Capital Stock, or all or substantially all assets, of such Guarantor in accordance with the applicable provisions of this Indenture following which such Guarantor is no longer a Restricted Subsidiary of the Parent;

(b) if the Parent designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture;

(c) upon Legal Defeasance, Covenant Defeasance or satisfaction and discharge of this Indenture as provided in Articles 8 and 11 hereof;

(d) to the extent that such Guarantor is not an Immaterial Subsidiary solely due to the operation of clause (i) of the definition of “Immaterial Subsidiary,” upon the release of the guarantee referred to in such clause; or

(e) in the case of a Note Guarantee made by a Guarantor as a result of its Guarantee of Triggering Indebtedness pursuant to Section 4.18, the release of such Guarantor from the relevant Indebtedness (except in the case of Indebtedness under the Credit Agreement, a release resulting from the repayment in full of such Indebtedness).

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of, premium on, if any, and interest on, the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

100

ARTICLE 11

SATISFACTION AND DISCHARGE

Section 11.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:
