For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, amalgamations, consolidations and discontinued operations (as determined in accordance with GAAP), in each case with respect to an operating unit of a business, and any operational changes that Holdings or any Restricted Subsidiary has determined to make and/or made during the four-quarter reference period or subsequent to such reference

23

period and on or prior to or simultaneously with the Calculation Date shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, amalgamations, consolidations, discontinued operations and other operational changes (and the change of any associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into Holdings or any Restricted Subsidiary since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation, amalgamation, discontinued operation or operational change, in each case with respect to an operating unit of a business, that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, discontinued operation, merger, amalgamation, consolidation or operational change had occurred at the beginning of the applicable four-quarter period. If since the beginning of such period any Restricted Subsidiary is designated an Unrestricted Subsidiary or any Unrestricted Subsidiary is designated a Restricted Subsidiary, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such designation had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to any event, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of Holdings.

If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness if such Hedging Obligation has a remaining term in excess of 12 months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of Holdings to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as Holdings may designate.

For purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on the average exchange rate for such currency for the

(2)                                 the issue price and issuance date of such Additional Notes, including the date from which interest on such Additional Notes shall accrue; and

(3)                                 if applicable, that such Additional Notes shall be issuable in whole or in part in the form of one or more Global Notes and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be borne by such Global Notes in addition to or in lieu of those set forth in Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Section 2.2 of Appendix A in which any such Global Note may be exchanged in whole or in part for

54

Additional Notes registered, or any transfer of such Global Note in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Note or a nominee thereof.

If any of the terms of any Additional Notes are established by action taken pursuant to a resolution of the Board of Directors, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of Holdings and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate or an indenture supplemental hereto setting forth the terms of the Additional Notes.

The Initial Notes and any Additional Notes may, at the Issuers’ option, be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, the Additional Notes will have a separate CUSIP number, if applicable.

SECTION 2.02              Form and Dating.  Provisions relating to the Initial Notes are set forth in Appendix A, which is hereby incorporated in and expressly made a part of this Indenture.  The (i) Initial Notes and the Trustee’s certificate of authentication and (ii) any Additional Notes and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture.  The Notes may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuers or any Subsidiary Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer).  Each Note shall be dated the date of its authentication.  The Notes shall be issuable only in registered form without interest coupons and in denominations of $2,000 and any integral multiples of $1,000 in excess thereof, provided that Notes may be issued in denominations of less than $2,000 solely to accommodate book-entry positions that have been created by participants of the Depository in denominations of less than $2,000.

SECTION 2.03              Execution and Authentication.  The Trustee shall authenticate and make available for delivery upon a written order of the Issuers signed by one Officer of each Issuer (a) Initial Notes for original issue on the date hereof in an aggregate principal amount of $1,000,000,000 and (b) subject to the terms of this Indenture, Additional Notes in an aggregate principal amount to be determined at the time of issuance and specified therein.  Such order shall specify the amount of separate Note certificates to be authenticated, the principal amount of each of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, whether the Notes are to be Initial Notes or Additional Notes the registered holder of each of the Notes and delivery instructions.  Notwithstanding anything to the contrary in this Indenture or Appendix A, any issuance of Additional Notes after the Issue Date shall be in a principal amount of at least $2,000 and integral multiples of $1,000 in excess thereof.

One Officer shall sign the Notes for each of the Issuers by manual or facsimile signature.

55

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

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

The Trustee may appoint one or more authenticating agents reasonably acceptable to Holdings to authenticate the Notes.  Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to Holdings.  Unless limited by the terms of such appointment, 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 any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.04              Registrar and Paying Agent.

(a)                                 The Issuers shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an office or agency where Notes may be presented for payment (the “Paying Agent”).  The Registrar shall keep a register of the Notes and of their transfer and exchange.  The Issuers may have one or more co-registrars and one or more additional paying agents.  The term “Registrar” includes any co-registrars.  The term “Paying Agent” includes the Paying Agent and any additional paying agents.  The Issuers initially appoint the Trustee as Registrar, Paying Agent and the Notes Custodian with respect to the Global Notes.

(b)                                 The Issuers may enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture.  The agreement shall implement the provisions of this Indenture that relate to such agent.  Holdings shall notify the Trustee in writing of the name and address of any such agent.  If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07.  Holdings or any of its domestically organized Wholly Owned Subsidiaries may act as Paying Agent or Registrar.

(c)                                  The Issuers may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor Registrar or Paying Agent, as the case may be, as evidenced by an appropriate agreement entered into by the Issuers and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above.  The Registrar or Paying Agent may resign at any time upon written notice to the Issuers and the Trustee; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08.

SECTION 2.05              Paying Agent to Hold Money in Trust.  On or prior to each due date of the principal of and interest on any Note, the Issuers shall deposit with each Paying

56

Agent (or if Holdings or a Wholly Owned Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due.  The Issuers shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Notes, and shall notify the Trustee of any default by the Issuers in making any such payment.  If Holdings or a Wholly Owned Subsidiary of Holdings acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto.  The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent.  Upon complying with this Section 2.05, a Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.06              Holder Lists.  The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of holders.  If the Trustee is not the Registrar, Holdings shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of holders.

SECTION 2.07              Transfer and Exchange.  The Notes shall be issued in registered form and shall be transferable only upon the surrender of a Note for registration of transfer and in compliance with Appendix A.  When a Note is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are met.  When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the same requirements are met.  To permit registration of transfers and exchanges, the Issuers shall execute and the Trustee shall authenticate Notes at the Registrar’s request.  The Issuers may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section.  The Issuers shall not be required to make, and the Registrar need not register, transfers or exchanges of Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed) or transfer or exchanges of any Notes for a period of 15 days before a selection of Notes to be redeemed or between a Record Date and the related Interest Payment Date.

Prior to the due presentation for registration of transfer of any Note, the Issuers, the Subsidiary Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest, if any, on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Issuers, the Subsidiary Guarantors, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

Any holder of a beneficial interest in a Global Note shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the holder of such Global Note (or

57

its agent) or (b) any holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry.

All Notes issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Notes surrendered upon such transfer or exchange.

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

None of the Trustee, Registrar or Paying Agent shall have any responsibility for any actions taken or not taken by the Depository.

SECTION 2.08              Replacement Notes.  If a mutilated Note is surrendered to the Registrar or if the holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a replacement Note if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the holder (a) satisfies the Issuers and the Trustee within a reasonable time after such holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuers and the Trustee prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Issuers and the Trustee.  If required by the Trustee or the Issuers, such holder shall furnish an indemnity bond or security sufficient in the judgment of the Trustee, with respect to the Trustee, and the Issuers, with respect to the Issuers, to protect the Issuers, the Trustee, the Paying Agent and the Registrar, as applicable, from any loss or liability that any of them may suffer if a Note is replaced and subsequently presented or claimed for payment.  The Issuers and the Trustee may charge the holder for their expenses in replacing a Note (including without limitation, attorneys’ fees and disbursements in replacing such Note).  In the event any such mutilated, lost, destroyed or wrongfully taken Note has become or is about to become due and payable, the Issuers in their discretion may pay such Note instead of issuing a new Note in replacement thereof.

Every replacement Note is an additional obligation of the Issuers.

The provisions of this Section 2.08 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes.

SECTION 2.09              Outstanding Notes.  Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for

58

cancellation and those described in this Section as not outstanding.  Subject to Section 14.06, a Note does not cease to be outstanding because one of the Issuers or an Affiliate of one of the Issuers holds the Note.

If a Note is replaced pursuant to Section 2.08 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuers receive proof satisfactory to them that the replaced Note is held by a protected purchaser.  A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.08.

If a Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying such money to the holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10              Cancellation.  The Issuers at any time may deliver Notes to the Trustee for cancellation.  The Registrar and each Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment.  The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Notes in accordance with its customary procedures.  The Issuers may not issue new Notes to replace Notes they have  redeemed, paid or delivered to the Trustee for cancellation.  The Trustee shall not authenticate Notes in place of canceled Notes other than pursuant to the terms of this Indenture.

SECTION 2.11              Defaulted Interest.  If the Issuers default in a payment of interest on the Notes, the Issuers shall pay the defaulted interest then borne by the Notes (plus interest on such defaulted interest to the extent lawful) in any lawful manner.  The Issuers may pay the defaulted interest to the Persons who are holders on a subsequent special record date.  The Issuers shall fix or cause to be fixed any such special record date and payment date, which specified record date shall not be less than 10 days prior to the payment date for such defaulted interest, and shall promptly mail or cause to be mailed to each affected holder, or otherwise deliver in accordance with the procedures of the Depository, a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.  The Issuers shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on the Notes and the date of the proposed payment, and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest, or make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when so deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.11.

SECTION 2.12              CUSIP Numbers, ISINs, Etc.  The Issuers in issuing the Notes may use CUSIP numbers, ISINs and “Common Code” numbers (if then generally in use), and the Trustee shall use any such CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the

59

Notes or as contained in any notice of a redemption that reliance may be placed only on the other identification numbers printed on the Notes and that any such redemption shall not be affected by any defect in or omission of such numbers.  The Issuers shall advise the Trustee of any change in any such CUSIP numbers, ISINs and “Common Code” numbers.

SECTION 2.13              Calculation of Principal Amount of Notes.  The aggregate principal amount of the Notes, at any date of determination, shall be the principal amount of the Notes at such date of determination.  With respect to any matter requiring consent, waiver, approval or other action of the holders of a specified percentage of the principal amount of all the Notes, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Notes, the holders of which have so consented, by (b) the aggregate principal amount, as of such date of determination, of the Notes then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.09 and Section 14.06 of this Indenture.  Any calculation of the Applicable Premium made pursuant to this Indenture or the Notes shall be made by Holdings and delivered to the Trustee pursuant to an Officers’ Certificate.

The Issuers shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Notes to be redeemed pursuant to Section 3.04.

60

SECTION 3.04              Selection of Notes to Be Redeemed.  In the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed (as notified to the Trustee in writing by the Issuers), or if the Notes are not so listed, on a pro rata basis to the extent practicable or by lot or by such other method as the Trustee shall deem fair and appropriate (and, in such manner that complies with the  requirements of the Depository, if applicable); provided that no Notes of $2,000 (and integral multiples of $1,000 in excess thereof) or less shall be redeemed in part.  The Trustee shall make the selection from outstanding Notes not previously called for redemption.  The Trustee may select for redemption portions of the principal of Notes that have denominations larger than $2,000.  Notes and portions of them the Trustee selects shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof.  Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.  The Trustee shall notify the Issuers promptly of the Notes or portions of Notes to be redeemed.

(1)                                 in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of permitted Indebtedness described in clauses (i) through (xxii) of Section 4.03(b) above or is entitled to be Incurred pursuant to Section 4.03(a), then Holdings shall, in its sole discretion, classify or reclassify (as if Incurred at such later time), or later divide, classify or reclassify, such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies with this Section 4.03; provided, that (A) only Indebtedness outstanding under the Credit Agreement in excess of $2,000.0 million may be classified or reclassified as not Incurred under Section 4.03(b)(i) and (B) the Existing 9.375% Senior Notes and the Second Lien Term Facility (including any guarantees thereof) outstanding on the Acquisition Date shall at all times be treated as Incurred pursuant to Section 4.03(b)(ii);

(2)                                 at the time of Incurrence, Holdings will be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 4.03(a) and (b) without giving pro forma effect to the Indebtedness Incurred pursuant to Section 4.03(b) when calculating the amount of Indebtedness that may be Incurred pursuant to Section 4.03(a);

(3)                                 in connection with the Incurrence or issuance, as applicable, of any Indebtedness, Disqualified Stock or Preferred Stock, the Issuer or applicable Restricted Subsidiary may elect at any time prior to the actual Incurrence or issuance of such Indebtedness, Disqualified Stock or Preferred Stock, as applicable, to treat all or any portion of the commitments relating to such Indebtedness, Disqualified Stock or Preferred Stock as being Incurred or issued on the date of such election, and any related subsequent actual Incurrence or issuance of such Indebtedness, Disqualified Stock or Preferred Stock will be deemed for all purposes under this Indenture to have been Incurred on the date of such election;

(4)                                 if any Indebtedness denominated in U.S. dollars is exchanged, converted or refinanced into Indebtedness denominated in a foreign currency, then (in connection with such exchange, conversion or refinancing, and thereafter), the U.S. dollar amount limitations set forth in any of clauses (i) through (xxii) of Section 4.03(b) above with respect to such exchange, conversion or refinancing shall be deemed to be the amount of such foreign currency, as applicable, into which such Indebtedness has been exchanged, converted or refinanced at the time of such exchange, conversion or refinancing; and

(5)                                 if any Indebtedness denominated in a foreign currency is exchanged, converted or refinanced into Indebtedness denominated in U.S. dollars, then (in connection with such exchange, conversion or refinancing, and thereafter), the U.S. dollar amount limitations set forth in any of clauses (i) through (xxii) of Section 4.03(b) with respect to such exchange, conversion or refinancing shall be deemed to be the amount of U.S. dollars into which such Indebtedness has been exchanged, converted or refinanced at the time of such exchange, conversion or refinancing.

72

Accrual of interest, the accretion of accreted value, the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred Stock, as applicable, amortization of original issue discount, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies will not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness; provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness other than as provided in clauses (3) and (4) above, 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 or first Incurred (whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt.

Notwithstanding any other provision of this Section 4.03, the maximum amount of Indebtedness that Holdings and its Restricted Subsidiaries may Incur pursuant to this Section 4.03 shall not be deemed to be exceeded, with respect to any outstanding Indebtedness, solely as a result of fluctuations in the exchange rate of currencies.

SECTION 4.04              Limitation on Restricted Payments.

(a)                                 Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly:

(i)                                     declare or pay any dividend or make any distribution on account of any of Holdings’ or any of the Restricted Subsidiaries’ Equity Interests, including any payment made in connection with any merger, amalgamation or consolidation involving Holdings (other than (A) dividends or distributions payable solely in Equity Interests (other than Disqualified Stock) of Holdings; or (B) dividends or distributions by a Restricted Subsidiary so long as, in the case of any dividend or distribution payable on or in respect of any class or series of securities issued by a Restricted Subsidiary that is not a Wholly Owned Restricted Subsidiary, Holdings or a Restricted Subsidiary receives at least its pro rata share of such dividend or distribution in accordance with its Equity Interests in such class or series of securities);

(ii)                                  purchase or otherwise acquire or retire for value any Equity Interests of Holdings or any direct or indirect parent of Holdings;

(iii)                               make any principal payment on, or redeem, repurchase, defease or otherwise acquire or retire for value, in each case prior to any scheduled repayment or scheduled maturity, any Subordinated Indebtedness of an Issuer or any Subsidiary Guarantor (other than the payment, redemption, repurchase, defeasance, acquisition or retirement of (A) Subordinated Indebtedness in anticipation of satisfying a sinking fund

73

obligation, principal installment or final maturity, in each case due within one year of the date of such payment, redemption, repurchase, defeasance, acquisition or retirement and (B) Indebtedness permitted under clauses (vii) and (ix) of Section 4.03(b)); or

(iv)                              make any Restricted Investment

(all such payments and other actions set forth in clauses (i) through (iv) above being collectively referred to as “Restricted Payments”), unless, at the time of such Restricted Payment:

(1)                                 no Default shall have occurred and be continuing or would occur as a consequence thereof;

(2)                                 immediately after giving effect to such transaction on a pro forma basis, Holdings could Incur $1.00 of additional Indebtedness under Section 4.03(a); and

(3)                                 such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Holdings and the Restricted Subsidiaries after the Original Issue Date (including Restricted Payments permitted by clauses (i), (ii) (with respect to the payment of dividends on Refunding Capital Stock (as defined below) pursuant to clause (C) thereof), (vi)(C), (viii) and (xiii)(B) of Section 4.04(b), but excluding all other Restricted Payments permitted by Section 4.04(b)), is less than the amount equal to the Cumulative Credit.

(b)                                 The provisions of Section 4.04(a) shall not prohibit:

(i)                                     the payment of any dividend or distribution or the consummation of any irrevocable redemption within 60 days after the date of declaration thereof, if at the date of declaration or the giving notice of such irrevocable redemption, as applicable, such payment would have complied with the provisions of this Indenture;

(B)                               the declaration and payment of dividends on the Retired Capital Stock out of the proceeds of the substantially concurrent sale (other than to a Subsidiary of Holdings) of Refunding Capital Stock, and

(C)                               if immediately prior to the retirement of Retired Capital Stock, the declaration and payment of dividends thereon was permitted under clause (vi) of this Section 4.04(b) and not made pursuant to clause (ii)(B), the declaration and payment of dividends on the Refunding Capital Stock (other than Refunding Capital Stock the proceeds of which were used to redeem, repurchase, retire or otherwise acquire any Equity Interests of any direct or indirect parent of Holdings) in an aggregate amount per

74

year no greater than the aggregate amount of dividends per annum that were declarable and payable on such Retired Capital Stock immediately prior to such retirement;

(iii)                               the redemption, repurchase, defeasance, or other acquisition or retirement of Subordinated Indebtedness of an Issuer or any Subsidiary Guarantor made by exchange for, or out of the proceeds of the substantially concurrent sale of, new Indebtedness of an Issuer or a Subsidiary Guarantor which is Incurred in accordance with Section 4.03 so long as:

(A)                               the principal amount (or accreted value, if applicable) of such new Indebtedness does not exceed the principal amount (or accreted value, if applicable), plus any accrued and unpaid interest, of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired for value (plus the amount of any premium required to be paid under the terms of the instrument governing the Subordinated Indebtedness being so redeemed, repurchased, acquired or retired, any tender premiums, plus any defeasance costs, fees and expenses Incurred in connection therewith),

(B)                               such Indebtedness is subordinated to the Notes or the related Subsidiary Guarantee, as the case may be, at least to the same extent as such Subordinated Indebtedness so purchased, exchanged, redeemed, repurchased, defeased, acquired or retired for value,

(C)                               such Indebtedness has a final scheduled maturity date equal to or later than the earlier of (x) the final scheduled maturity date of the Subordinated Indebtedness being so redeemed, repurchased, acquired or retired and (y) 91 days following the last maturity date of any Notes then outstanding, and

(D)                               such Indebtedness has a Weighted Average Life to Maturity at the time Incurred which is not less than the shorter of (x) the remaining Weighted Average Life to Maturity of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired and (y) the Weighted Average Life to Maturity that would result if all payments of principal on the Subordinated Indebtedness being redeemed, repurchased, defeased, acquired or retired that were due on or after the date that is one year following the last maturity date of any Notes then outstanding were instead due on such date;

(iv)                              a Restricted Payment to pay for the repurchase, retirement or other acquisition for value of Equity Interests of Holdings or any direct or indirect parent of Holdings held by any future, present or former employee, director, officer, manager or consultant of Holdings or any direct or indirect parent of Holdings or any Subsidiary of Holdings pursuant to any management equity plan or stock option plan or any other management or employee benefit plan or other agreement or arrangement; provided, however, that the aggregate Restricted Payments made under this clause (iv) do not exceed $50.0 million in any calendar year (which shall increase to $100.0 million subsequent to the consummation of an underwritten public Equity Offering of common stock), with unused amounts in any calendar year being permitted to be carried over to

75

succeeding calendar years subject to a maximum of $75.0 million in any calendar year (which shall increase to $150.0 million subsequent to the consummation of an underwritten public Equity Offering); provided, further, however, that such amount in any calendar year may be increased by an amount not to exceed:

(A)                               the cash proceeds received by Holdings or any of the Restricted Subsidiaries from the sale of Equity Interests (other than Disqualified Stock) of Holdings or any direct or indirect parent of Holdings (to the extent contributed to Holdings) to employees, directors, officers, managers or consultants of Holdings and the Restricted Subsidiaries or any direct or indirect parent of Holdings that occurs after the Acquisition Date (provided that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend will not increase the amount available for Restricted Payments under Section 4.04(a)(iii)), plus

(B)                               the cash proceeds of key man life insurance policies received by Holdings or any direct or indirect parent of Holdings (to the extent contributed to Holdings) or the Restricted Subsidiaries after the Acquisition Date;

provided that Holdings may elect to apply all or any portion of the aggregate increase contemplated by clauses (A) and (B) above in any calendar year; and provided, further, that cancellation of Indebtedness owing to Holdings or any Restricted Subsidiary from any present or former employees, directors, managers, officers or consultants of Holdings, any Restricted Subsidiary or the direct or indirect parents of Holdings in connection with a repurchase of Equity Interests of Holdings or any of its direct or indirect parents will not be deemed to constitute a Restricted Payment for purposes of this Section 4.04 or any other provision of this Indenture;

(v)                                 the declaration and payment of dividends or distributions to holders of any class or series of Disqualified Stock of Holdings or any Restricted Subsidiary issued or Incurred in accordance with Section 4.03;

76

provided, however, in the case of each of clauses (A) and (C) above of this clause (vi), that for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date of issuance of such Designated Preferred Stock, after giving effect to such issuance (and the payment of dividends or distributions) on a pro forma basis (including a pro forma application of the net proceeds therefrom), Holdings would have had a Fixed Charge Coverage Ratio of at least 2.00 to 1.00;

(vii)                           Investments in Unrestricted Subsidiaries having an aggregate Fair Market Value (as determined in good faith by Holdings), taken together with all other Investments made pursuant to this clause (vii) that are at that time outstanding, not to exceed the greater of $175.0 million and 2.5% of Adjusted Consolidated Net Tangible Assets at the time of such Investment plus an amount equal to any returns (including dividends, interest, distributions, returns of principal, profits on sale, repayments, income and similar amounts) actually received in respect of any such Investment made pursuant to this clause (vii) (with the Fair Market Value of each Investment being measured at the time made and without giving effect to subsequent changes in value); provided, however, that if any Investment pursuant to this clause (vii) is made in any Person that is not an Issuer or a Restricted Subsidiary at the date of the making of such Investment and such Person becomes an Issuer or a Restricted Subsidiary after such date, such Investment shall thereafter be deemed to have been made pursuant to clause (1) of the definition of Permitted Investments and shall cease to have been made pursuant to this clause (vii) for so long as such Person continues to be an Issuer or a Restricted Subsidiary;

(viii)                        the payment of dividends after a public offering of Capital Stock of Holdings or any direct or indirect parent of Holdings on Holdings’ Capital Stock (or a Restricted Payment to any such direct or indirect parent of Holdings to fund the payment by such direct or indirect parent of Holdings of dividends on such entity’s Capital Stock) of up to 6% per annum of the total market capitalization of Holdings or any such direct or indirect parent of Holdings as of the date of such public offering, other than public offerings with respect to Holdings’ (or such direct or indirect parent’s) Capital Stock registered on Form S-4 or Form S-8 and other than any public sale constituting an Excluded Contribution;

(xiii)                        any Restricted Payment, if applicable:

(B)                               in amounts required for any direct or indirect parent of Holdings, if applicable, to pay interest and/or principal on Indebtedness the proceeds of which

78

have been contributed to Holdings or any Restricted Subsidiary and that has been guaranteed by, or is otherwise considered Indebtedness of, Holdings Incurred in accordance with Section 4.03; and

(C)                               in amounts required for any direct or indirect parent of Holdings to pay fees and expenses related to any unsuccessful equity or debt offering of such parent;

(xviii)                 payments or distributions to dissenting stockholders pursuant to applicable law, pursuant to or in connection with a consolidation, amalgamation, merger or transfer of all or substantially all of the assets of Holdings and the Restricted Subsidiaries, taken as a whole, that complies with Section 5.01; provided that as a result of such consolidation, amalgamation, merger or transfer of assets, Holdings shall have made a Change of Control Offer (if required by this Indenture) and that all Notes tendered by holders in connection with such Change of Control Offer have been repurchased, redeemed or acquired for value; and

(xix)                       any Restricted Payment used to fund the Acquisition Transactions and the payment of fees and expenses Incurred in connection with the Acquisition Transactions or owed by Holdings or any direct or indirect parent of Holdings or Restricted Subsidiaries of Holdings to Affiliates, and any other payments made, including any such payments made to any direct or indirect parent of Holdings to enable it to make payments in connection with the consummation of the Acquisition Transactions, whether payable on the Original Issue Date or thereafter, in each case to the extent permitted by Section 4.07;

provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under clauses (vi)(B), (vii), (x), (xi) and (xiii)(B) of this Section 4.04(b), no Default shall have occurred and be continuing or would occur as a consequence thereof; provided,

further that any Restricted Payments made with property other than cash shall be calculated using the Fair Market Value (as determined in good faith by Holdings) of such property.

(c)                                  As of the Issue Date, all of the Subsidiaries of Holdings will be Restricted Subsidiaries. Holdings will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the definition of “Unrestricted Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by Holdings and the Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investments.”  Such designation will only be permitted if a Restricted Payment or Permitted Investment in such amount would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

SECTION 4.05              Dividend and Other Payment Restrictions Affecting Subsidiaries.  Holdings shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Issuer or Restricted Subsidiary to:

80

applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired;

(5)                                 contracts or agreements for the sale of assets, including any restriction with respect to a Restricted Subsidiary imposed pursuant to an agreement entered into for the sale or disposition of the Capital Stock or assets of such Restricted Subsidiary;

(6)                                 Secured Indebtedness otherwise permitted to be Incurred pursuant to Section 4.03 and Section 4.12 that limit the right of the debtor to dispose of the assets securing such Indebtedness;

(10)                          customary provisions contained in leases, licenses and other similar agreements entered into in the ordinary course of business;

(11)                          in the case of clause (c) above, any encumbrance or restriction that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease (including leases governing leasehold interests or Farm-In Agreements or Farm-Out Agreements relating to leasehold interests in Oil and Gas Properties), license or similar contract, or the assignment or transfer of any such lease (including leases governing leasehold interests or Farm-In Agreements or Farm-Out Agreements relating to leasehold interests in Oil and Gas Properties), license (including, without limitation, licenses of intellectual property) or other contracts;

81

(14)                          any Restricted Investment not prohibited by Section 4.04 and any Permitted Investment;

(15)                          any customary encumbrances or restrictions imposed pursuant to any agreement of the type described in the definition of “Permitted Business Investment”; or

(16)                          any encumbrances or restrictions of the type referred to in Section 4.05(a), (b) or (c) above imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (15) above; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of Holdings, no more restrictive with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

For purposes of determining compliance with this Section 4.05, (i) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common stock shall not be deemed a restriction on the ability to make distributions on Capital Stock and (ii) the subordination of loans or advances made to Holdings or a Restricted Subsidiary to other Indebtedness Incurred by Holdings or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances.

SECTION 4.06              Asset Sales.

(ii)                                  any notes or other obligations or other securities or assets received by Holdings or such Restricted Subsidiary from such transferee that are converted by Holdings or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received),

82

completion or production of such Oil and Gas Properties and activities related thereto agreed to be assumed by the transferee (or an Affiliate thereof),

(iv)                              Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that Holdings and each other Restricted Subsidiary are released from any guarantee of payment of such Indebtedness in connection with the Asset Sale (without duplication of Section 4.06(a)(i) hereto),

(v)                                 consideration consisting of Indebtedness of Holdings or any Restricted Subsidiary (other than Subordinated Indebtedness) received after the Issue Date from Persons who are not Holdings or any Restricted Subsidiary in connection with the Asset Sale and that is cancelled, and

(vi)                              any Designated Non-cash Consideration received by Holdings or any Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value (as determined in good faith by Holdings), taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.06(a)(vi) that is at that time outstanding, not to exceed the greater of 4% of Adjusted Consolidated Net Tangible Assets and $300.0 million at the time of the receipt of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value),

shall be deemed to be Cash Equivalents for the purposes of this Section 4.06(a).

(b)                                 Within 365 days after Holdings’ or any Restricted Subsidiary’s receipt of the Net Proceeds of any Asset Sale, Holdings or such Restricted Subsidiary may apply the Net Proceeds from such Asset Sale, at its option:

(i)                                     to repay (A) Indebtedness constituting First-Priority Lien Obligations and other Pari Passu Indebtedness that is secured by a Lien permitted under this Indenture (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto), (B) Indebtedness of a Restricted Subsidiary that is not a Subsidiary Guarantor, (C) Obligations under the Notes or (D) other Pari Passu Indebtedness (provided that if an Issuer or any Subsidiary Guarantor shall so reduce Obligations under Pari Passu Indebtedness that does not constitute First-Priority Lien Obligations or Indebtedness that is secured by a Lien on the Collateral that is senior in priority to the Notes Obligations, the Issuers will equally and ratably reduce Obligations under the Notes pursuant to Section 3.01), through open-market purchases (provided that such purchases (i) are at or above 100% of the principal amount thereof or, in the event that the Notes were issued with significant original issue discount, 100% of the accreted value thereof and (ii) do not include Indebtedness owed to Holdings or an Affiliate of Holdings) or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all holders to purchase at a purchase price equal to 100% of the principal amount thereof or, in the event that the Notes were issued with significant original issue discount, 100% of the accreted value thereof (plus accrued and unpaid interest, if any, the pro rata principal amount of Notes);

83

(ii)                                  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, such acquisition results in such Person becoming a Restricted Subsidiary of Holdings), assets, or property or capital expenditures, in each case (A) used or useful in a Similar Business or (B) that replace the properties and assets that are the subject of such Asset Sale, or to reimburse the cost of any of the foregoing incurred on or after the date on which the Asset Sale giving rise to such Net Proceeds was contractually committed; or

(iii)                               to invest in Additional Assets.

In the case of Section 4.06(b)(ii), a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment until the 18-month anniversary of the date of the receipt of such Net Proceeds; provided that in the event such binding commitment is later canceled or terminated for any reason before such Net Proceeds are so applied, then such Net Proceeds shall constitute Excess Proceeds unless Holdings or such Restricted Subsidiary enters into another binding commitment (a “Second Commitment”) within six months of such cancellation or termination of the prior binding commitment; provided, further, that Holdings or such Restricted Subsidiary may only enter into a Second Commitment under the foregoing provision one time with respect to each Asset Sale and to the extent such Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied or are not applied within 180 days of such Second Commitment, then such Net Proceeds shall constitute Excess Proceeds.

Pending the final application of any such Net Proceeds, Holdings or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture. Any Net Proceeds from any Asset Sale that are not applied as provided and within the time period set forth in the first sentence of this Section 4.06(b) (it being understood that any portion of such Net Proceeds used to make an offer to purchase Notes, as described in clause (i) of this Section 4.06(b), shall be deemed to have been invested whether or not such offer is accepted) will be deemed to constitute “Excess Proceeds.”  When the aggregate amount of Excess Proceeds exceeds $50.0 million, the Issuers shall make an offer to all holders of Notes (and, at the option of the Issuers, to holders of any Pari Passu Indebtedness) (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes (and such Pari Passu Indebtedness), that is at least $2,000 and an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof (or, in the event the Notes or such Pari Passu Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest, if any (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness), to (but not including) the date fixed for the closing of such offer, in accordance with the procedures set forth in this Section 4.06. The Issuers will commence an Asset Sale Offer with respect to Excess Proceeds within ten (10) Business Days after the date that Excess Proceeds exceeds $50.0 million by mailing, or delivering electronically if held by the Depository, the notice required pursuant to the terms of Sections 3.05 and 4.06(f), with a copy to the Trustee. To the extent that the aggregate amount of Notes (and such Pari Passu Indebtedness) tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, Holdings may use any remaining Excess Proceeds for any purpose that is not prohibited by this

84

Indenture. If the aggregate principal amount of Notes (and such Pari Passu Indebtedness) surrendered by holders thereof exceeds the amount of Excess Proceeds, the Issuers shall select the Notes to be purchased in the manner described in Section 4.06(e). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(c)                                  The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuers will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(d)                                 Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided above, Holdings shall deliver to the Trustee an Officers’ Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the compliance of such allocation with the provisions of Section 4.06(b).  On such date, the Issuers shall also irrevocably deposit with the Trustee or with a paying agent (or, if an Issuer or a Wholly Owned Restricted Subsidiary is acting as the Paying Agent, segregate and hold in trust) an amount equal to the Excess Proceeds to be invested in Cash Equivalents, as directed in writing by Holdings and to be held for payment in accordance with the provisions of this Section 4.06.  Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer Period”), the Issuers shall deliver to the Trustee for cancellation the Notes or portions thereof that have been properly tendered to and are to be accepted by the Issuers.  The Trustee (or the Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering holder in the amount of the purchase price.  In the event that the Excess Proceeds delivered by the Issuers to the Trustee are greater than the purchase price of the Notes tendered, the Trustee shall deliver the excess to the Issuers immediately after the expiration of the Offer Period for application in accordance with this Section 4.06.

(e)                                  Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuers at the address specified in the notice at least three Business Days prior to the purchase date.  Holders shall be entitled to withdraw their election if the Trustee or an Issuer receives not later than one Business Day prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered by the holder for purchase and a statement that such holder is withdrawing his election to have such Note purchased.  If more Notes (and such Pari Passu Indebtedness) are tendered pursuant to an Asset Sale Offer than the Issuers are required to purchase, selection of such Notes for purchase shall be made by the Issuers in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed (and the Issuers shall notify the Trustee of any such listing), or if such Notes are not so listed, on a pro rata basis to the extent practicable, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with the procedures of the Depository, if applicable); provided that no Notes of $2,000 or less shall be purchased in part.  Selection of such Pari Passu Indebtedness shall be made pursuant to the terms of such Pari Passu Indebtedness.

85

(f)                                   Notices of an Asset Sale Offer shall be mailed by first class mail, postage prepaid, or delivered electronically if held by the Depository, at least 30 but not more than 60 days before the purchase date to each holder of Notes at such holder’s registered address. If any Note is to be purchased in part only, any notice of purchase that relates to such Note shall state the portion of the principal amount thereof that has been or is to be purchased.

(a)                                 Holdings shall not, and shall not permit any of the Restricted Subsidiaries to, directly or indirectly, 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 or series of transactions, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of Holdings (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration in excess of $20.0 million, unless:

In the event that at the time of such Change of Control, the terms of the Bank Indebtedness restrict or prohibit the repurchase of Notes pursuant to this Section 4.08, then prior to the delivery of the notice to holders provided for in Section 4.08(b) but in any event within 30 days following any Change of Control, the Issuers shall (i) repay in full all Bank Indebtedness or, if doing so will allow the purchase of Notes, offer to repay in full all Bank Indebtedness and repay the Bank Indebtedness of each lender and/or noteholder who has accepted such offer, or (ii) obtain the requisite consent under the agreements governing the Bank Indebtedness to permit the repurchase of the Notes as provided for in Section 4.08(b).

(i)                                     that a Change of Control has occurred and that such holder has the right to require the Issuers to repurchase such holder’s Notes for the Change of Control Payment (subject to the right of holders of record on a Record Date to receive interest on the relevant Interest Payment Date);

(ii)                                  the circumstances regarding such Change of Control;

89

(iv)                              the instructions determined by the Issuers, consistent with this Section 4.08, that a holder must follow in order to have its Notes purchased.

(c)                                  Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuers at the address specified in the notice at least three Business Days prior to the purchase date.  The holders shall be entitled to withdraw their election if the Trustee or the Issuers receive not later than one Business Day prior to the purchase date a telegram, telex, facsimile transmission or letter setting forth the name of the holder, the principal amount of the Note which was delivered for purchase by the holder and a statement that such holder is withdrawing his election to have such Note purchased.  Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

(e)                                  A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(f)                                   Notwithstanding the foregoing provisions of this Section 4.08, the Issuers shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.08 applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer; or (ii) a notice of redemption of all outstanding Notes has been given pursuant to this Indenture unless and until there is a default in payment of the applicable redemption price.

(g)                                  If holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuers, or any third party making a Change of Control Offer in lieu of the Issuers as described above, purchase all of the Notes validly tendered and not withdrawn by such holders, the Issuers or such third party will have the right, upon not less than 30 nor more than 60 days’ prior written notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding following such purchase at a price in cash equal to the Change of Control Payment.

(h)                                 Notes repurchased by the Issuers pursuant to a Change of Control Offer will have the status of Notes issued but not outstanding or will be retired and canceled at the option of the Issuers.  Notes purchased by a third party pursuant to the preceding clause (f) will have the status of Notes issued and outstanding.

(i)                                     At the time the Issuers deliver Notes to the Trustee which are to be accepted for purchase, Holdings shall also deliver an Officers’ Certificate stating that such Notes are to be accepted by the Issuers pursuant to and in accordance with the terms of this

Section 4.08.  A Note shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or delivers payment therefor to the surrendering holder.

(j)                                    Prior to any Change of Control Offer, Holdings shall deliver to the Trustee an Officers’ Certificate stating that all conditions precedent contained herein to the right of the Issuers to make such offer have been complied with.

SECTION 4.09              Compliance Certificate.  Holdings shall deliver to the Trustee within 120 days after the end of each fiscal year of Holdings, beginning with the fiscal year ending on December 31, 2017,  an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of Holdings they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period.  If any Officer does, the certificate shall describe the Default, its status and what action the Issuers are taking or propose to take with respect thereto.  Except with respect to receipt of payments of principal and interest on the Notes and any Default or Event of Default information contained in the Officers’ Certificate delivered to it pursuant to this Section 4.09, the Trustee shall have no duty to review, ascertain or confirm the Issuers’ compliance with or the breach of any representation, warranty or covenant made in this Indenture.

SECTION 4.10              Further Instruments and Acts.  Upon request of the Trustee, the Issuers shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 4.11              Future Subsidiary Guarantors.  Holdings shall cause each Wholly Owned Restricted Subsidiary that is not an Excluded Subsidiary and that guarantees any Indebtedness (other than Junior Lien Obligations) of an Issuer or any of the Subsidiary Guarantors secured by the Collateral (other than Excluded Assets) to execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit D hereto pursuant to which such Wholly Owned Restricted Subsidiary will guarantee the Issuers’ Obligations under the Notes and this Indenture, as well as to execute and deliver a joinder to the applicable Intercreditor Agreement if required by such Intercreditor Agreement and to execute and deliver a joinder to each applicable Security Document to the extent required by Section 4.13.

SECTION 4.12              Liens.

(a)                                 Holdings shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist (i) any Lien (except Permitted Liens) on any asset or property of Holdings or such Restricted Subsidiary securing Indebtedness of Holdings or a Restricted Subsidiary or (ii) any Lien securing any First-Priority Lien Obligation

91

of Holdings or any Subsidiary Guarantor otherwise permitted under this Indenture without effectively providing that the Notes or the applicable Subsidiary Guarantee, as the case may be, shall be granted a junior-priority security interest (subject to Permitted Liens) upon the Collateral constituting the collateral for such First-Priority Lien Obligations, except in respect of Excluded Assets and limitations set forth in the Security Documents; provided, however, that if granting such security interests requires the consent of a third party, Holdings will use commercially reasonable efforts to obtain such consent with respect to the security interests for the benefit of the Notes Collateral Agent on behalf of the holders of the Notes; provided, further, however, that if such third party does not consent to the granting of such security interests after the use of commercially reasonable efforts, Holdings will not be required to provide such security interests.

(b)                                 [Reserved.]

(c)                                  For purposes of determining compliance with this Section 4.12, (i) a Lien securing an item of Indebtedness need not be permitted solely by reference to one category of permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to Section 4.12(a) but may be permitted in part under any combination thereof and (ii) in the event that a Lien securing an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of one or more of the categories of permitted Liens (or any portion thereof) described in the definition of “Permitted Liens” or pursuant to Section 4.12(a), Holdings shall, in its sole discretion, classify or reclassify (as if Incurred at such later time), or later divide, classify or reclassify, such Lien securing such item of Indebtedness (or any portion thereof) in any manner that complies with this covenant and will be entitled to include the amount and type of such Lien or such item of Indebtedness secured by such Lien (or any portion thereof) in one of the clauses of the definition of “Permitted Liens” or pursuant to Section 4.12(a) and such Lien securing such item of Indebtedness (or any portion thereof) will be treated as being Incurred or existing pursuant to only such clause or clauses (or any portion thereof) or pursuant to Section 4.12(a).

(d)                                 With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms or in the form of common stock of Holdings, the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class, accretion of original issue discount or liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness described in clause (3) of the definition of “Indebtedness.”

SECTION 4.13              After-Acquired Property.

Upon the acquisition by an Issuer or any Subsidiary Guarantor of any First-Priority After-Acquired Property, or upon any additional Restricted Subsidiary becoming a Subsidiary Guarantor required to pledge its existing First-Priority After-Acquired Property as Collateral pursuant to this Article IV, such Issuer or Subsidiary Guarantor shall execute and

92

deliver such mortgages, deeds of trust, security instruments, financing statements and other Security Documents as shall be reasonably necessary to vest in the Notes Collateral Agent, for the benefit of the Secured Parties (as defined in the Collateral Agreement), a perfected junior-priority security interest or lien, subject only to Liens permitted under Section 4.12, in such First-Priority After-Acquired Property and to have such First-Priority After-Acquired Property (but subject to the limitations as described in Article XI, the Security Documents, the Intercreditor Agreements and limitations under applicable local law) added to the Collateral, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such First-Priority After-Acquired Property to the same extent and with the same force and effect.

Notwithstanding the foregoing, if granting a security interest in any property pursuant to the foregoing requires the consent of a third party, Holdings shall use commercially reasonable efforts to obtain such consent with respect to such security interest for the benefit of the Notes Collateral Agent on behalf of the Trustee and the holders of the Notes. If such third party does not consent to the granting of such security interest after the use of such commercially reasonable efforts, the applicable entity will not be required to provide such security interest.

SECTION 4.14              Maintenance of Office or Agency.

(a)                                 The Issuers shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or Registrar) where Notes may be surrendered for registration of transfer or for exchange.  The Issuers shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency.  If at any time the Issuers shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office of the Trustee as set forth in Section 14.01.

(b)                                 The Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve an Issuer of its obligation to maintain an office or agency for such purposes.  The Issuers shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(c)                                  The Issuers hereby designates the Corporate Trust Office of the Trustee or its agent as such office or agency of the Issuers in accordance with Section 2.04.

SECTION 4.15              Covenant Suspension.  If on any date following the Issue Date, (i) the Notes have Investment Grade Ratings from both Rating Agencies, and (ii) no Default has occurred and is continuing under this Indenture, then, beginning on that day (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), and subject to the provisions of the following paragraph, the Issuers and the Restricted Subsidiaries shall not be subject to Sections 4.03, 4.04, 4.05, 4.06, 4.07, 4.11 and 5.01(a)(iv) (collectively the “Suspended Covenants”).

93

In the event that Holdings and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating, then Holdings and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events.  The Issuers will provide the Trustee with written notice of each Covenant Suspension Event or Reversion Date within five Business Days of the occurrence thereof.  The Trustee will have no duty to monitor or provide notice to the holders of Notes of any Covenant Suspension Event or Reversion Date.

On each Reversion Date, all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be classified as having been Incurred or issued pursuant to Sections 4.03(a) and (b) (to the extent such Indebtedness or Disqualified Stock or Preferred Stock would be permitted to be Incurred or issued thereunder as of the Reversion Date and after giving effect to Indebtedness Incurred or issued prior to the Suspension Period and outstanding on the Reversion Date). To the extent such Indebtedness or Disqualified Stock or Preferred Stock would not be so permitted to be Incurred or issued pursuant to Sections 4.03(a) and (b), such Indebtedness or Disqualified Stock or Preferred Stock will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(iii). Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.04 will be made as though Section 4.04 had been in effect since the Issue Date and prior to, but not during, the Suspension Period. Accordingly, Restricted Payments made during the Suspension Period will not reduce the amount available to be made as Restricted Payments under Section 4.04(a).  As described above, however, no Default or Event of Default will be deemed to have occurred on the Reversion Date as a result of any actions taken by Holdings or its Restricted Subsidiaries during the Suspension Period. Within 30 days of such Reversion Date, the Issuers must comply with the terms of Section 4.11.

For purposes of Section 4.06, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero.

SECTION 4.16              Maintenance of Insurance.  The Issuers shall maintain, with financially sound and reputable insurance companies, insurance (subject to customary deductibles and retentions) in such amounts and against such risks as are customarily maintained by similarly situated companies engaged in the same or similar businesses operating in the same or similar locations and cause the Issuers and the Subsidiary Guarantors to be listed as insured and the Notes Collateral Agent to be listed as co-loss payee on property and property casualty policies and as an additional insured on liability policies.  Notwithstanding the foregoing, the Issuers and the Subsidiary Guarantors may self-insure with respect to such risks with respect to which companies of established reputation in the same general line of business in the same general area usually self-insure.

(a)                                 Holdings may not, directly or indirectly, consolidate, amalgamate or merge with or into or wind up or convert into (whether or not Holdings is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to any Person unless:

(i)                                     Holdings is the surviving person or the Person formed by or surviving any such consolidation, amalgamation, merger, winding up or conversion (if other than Holdings) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation, partnership, limited liability company or similar entity organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (Holdings or such Person, as the case may be, being herein called the “Successor Holdco”); provided that in the case where the surviving Person is not a corporation, a co-obligor of the Notes is a corporation;

(ii)                                  the Successor Holdco (if other than Holdings) expressly assumes all the obligations of Holdings under this Indenture pursuant to supplemental indentures;

(iii)                               immediately after giving effect to such transaction (and treating any Indebtedness which becomes an obligation of the Successor Holdco, or any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Holdco, or such Issuer or such Restricted Subsidiary at the time of such transaction) no Default shall have occurred and be continuing;

(iv)                              immediately after giving pro forma effect to such transaction, as if such transaction had occurred at the beginning of the applicable four-quarter period (and treating any Indebtedness which becomes an obligation of the Successor Holdco, or any Restricted Subsidiary as a result of such transaction as having been Incurred by the Successor Holdco, or such Restricted Subsidiary at the time of such transaction), either

(1)                                 the Successor Holdco would be permitted to Incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.03(a); or

(2)                                 the Fixed Charge Coverage Ratio would be no less than such ratio immediately prior to such transaction;

(v)                                 if Holdings is not the Successor Holdco, each Subsidiary Guarantor, unless it is the other party to the transactions described above, shall have by supplemental indenture confirmed that its Subsidiary Guarantee shall apply to such Person’s obligations under this Indenture and the Notes; and

95

(vi)                              the Successor Holdco shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, amalgamation or transfer and such supplemental indentures (if any) comply with this Indenture.

The Successor Holdco (if other than Holdings) will succeed to, and be substituted for, Holdings under this Indenture and the Notes, and in such event Holdings will automatically be released and discharged from its obligations under this Indenture and the Notes. Notwithstanding the foregoing clauses (iii) and (iv) of this Section 5.01, (a) Holdings or any Restricted Subsidiary may merge, consolidate or amalgamate with or transfer all or part of its properties and assets to Holdings or to a Restricted Subsidiary, and (b) Holdings may merge, consolidate or amalgamate with an Affiliate incorporated solely for the purpose of reincorporating Holdings in another state of the United States, the District of Columbia or any territory of the United States or may convert into a corporation, partnership, limited liability company or similar entity, so long as the amount of Indebtedness of Holdings and the Restricted Subsidiaries is not increased thereby. This Article V will not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among Holdings and the Restricted Subsidiaries.

(b)                                 Subject to the provisions of Section 11.04 and Section 12.02(b)(i), no Subsidiary Guarantor shall, and Holdings shall not permit any Subsidiary Guarantor to, consolidate, amalgamate or merge with or into or wind up into (whether or not such Subsidiary Guarantor is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person unless:

(i)                                     either (A) such Subsidiary Guarantor is the surviving Person or the Person formed by or surviving any such consolidation, amalgamation or merger (if other than such Subsidiary Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a company, corporation, partnership or limited liability company (in the case of such Subsidiary Guarantor) or similar entity organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (such Subsidiary Guarantor or such Person, as the case may be, being herein called the “Successor Subsidiary Guarantor”) and the Successor Subsidiary Guarantor (if other than such Subsidiary Guarantor) expressly assumes all the obligations of such Subsidiary Guarantor under this Indenture and the Notes or the Subsidiary Guarantee, as applicable, pursuant to a supplemental indenture, or (B) such sale or disposition or consolidation, amalgamation or merger is not in violation of Section 4.06; and

(ii)                                  the Successor Subsidiary Guarantor (if other than such Subsidiary Guarantor) shall have delivered or caused to be delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger or transfer and such supplemental indenture (if any) comply with this Indenture.

96

Except as otherwise provided in this Indenture, the Successor Subsidiary Guarantor (if other than such Subsidiary Guarantor) will succeed to, and be substituted for, such Subsidiary Guarantor under this Indenture and the Notes or the Subsidiary Guarantee, as applicable, and such Subsidiary Guarantor will automatically be released and discharged from its obligations under this Indenture and its Subsidiary Guarantee. Notwithstanding the foregoing, (1) a Subsidiary Guarantor may merge, amalgamate or consolidate with an Affiliate incorporated solely for the purpose of reincorporating such Subsidiary Guarantor in another state of the United States, the District of Columbia or any territory thereof or may convert into a corporation, partnership, limited liability company or similar entity, so long as the amount of Indebtedness of such Subsidiary Guarantor is not increased thereby and (2) a Subsidiary Guarantor may merge, amalgamate or consolidate with Holdings or another Subsidiary Guarantor.

In addition, notwithstanding the foregoing, a Subsidiary Guarantor may consolidate, amalgamate or merge with or into or wind up into, liquidate, dissolve, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets (collectively, a “Transfer”) to Holdings or any Subsidiary Guarantor.

ARTICLE VI

DEFAULTS AND REMEDIES

SECTION 6.01              Events of Default.  An “Event of Default” occurs with respect to Notes if:

(a)                                 there is a default in any payment of interest on any Note when due and payable, and such default continues for a period of 30 days,

(b)                                 there is a default in the payment of principal or premium, if any, of any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise,

(c)                                  there is a failure by Holdings for 120 days after receipt of written notice given by the Trustee or the holders of not less than 30% in aggregate principal amount of the Notes then outstanding (with a copy to the Trustee) to comply with any of its obligations, covenants or agreements in Section 4.02,

(d)                                 there is a failure by Holdings or any Restricted Subsidiary for 60 days after written notice given by the Trustee or the holders of not less than 30% in principal amount of the Notes then outstanding (with a copy to the Trustee) to comply with its other obligations, covenants or agreements (other than a default referred to in clauses (a), (b) and (c) above) contained in the Notes or this Indenture,

(e)                                  there is a failure by Holdings or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay any Indebtedness (other than Indebtedness owing to Holdings or a Restricted Subsidiary) within any applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $125.0 million or its foreign currency equivalent,

97

(f)                                   Holdings or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) pursuant to or within the meaning of any Bankruptcy Law:

(i)                                     commences a voluntary case;

(ii)                                  consents to the entry of an order for relief against it in an involuntary case;

(iii)                               consents to the appointment of a Custodian of it or for any substantial part of its property; or

(iv)                              makes a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating to insolvency,

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

(i)                                     is for relief against Holdings or any Significant Subsidiary in an involuntary case;

(ii)                                  appoints a Custodian of Holdings or any Significant Subsidiary or for any substantial part of its property; or

(iii)                               orders the winding up or liquidation of Holdings or any Significant Subsidiary;

or any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days,

(h)                                 there is a failure by Holdings or any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $125.0 million or its foreign currency equivalent (net of any amounts which are covered by enforceable insurance policies issued by solvent carriers), which judgments are not discharged, waived or stayed for a period of 60 days,

(i)                                     the Subsidiary Guarantee of a Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) with respect to the Notes ceases to be in full force and effect (except as contemplated by the terms thereof) or an Issuer or any Subsidiary Guarantor that qualifies as a Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) denies or disaffirms its obligations under this Indenture or any Subsidiary Guarantee with respect to the Notes (except as contemplated by the terms of this Indenture) and such Default continues for 10 days,

(j)                                    unless such Liens have been released in accordance with the provisions of Article XI, the Security Documents or the Intercreditor Agreements, the Liens in favor of the holders of the Notes with respect to all or substantially all of the Collateral cease to be valid or enforceable and such Default continues for 30 days, or an Issuer shall assert or any Subsidiary Guarantor shall assert, in any pleading in any court of competent jurisdiction, that any such

98

security interest is invalid or unenforceable (except as contemplated by the terms of this Indenture) and, in the case of any Subsidiary Guarantor, the Issuers fail to cause such Subsidiary Guarantor to rescind such assertions within 30 days after the Issuers have actual knowledge of such assertions, or

(k)                                 the failure by an Issuer or any Subsidiary Guarantor for 60 days after notice to comply with its other agreements contained in the Security Documents except for a failure that would not be material to the holders of the Notes and would not materially affect the value of the Collateral taken as a whole.

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

However, a default under clause (c), (d) or (k) above shall not constitute an Event of Default until the Trustee or the holders of 30% in principal amount of outstanding Notes notify the Issuers, with a copy to the Trustee, of the default and the Issuers do not cure such default within the time specified in clauses (c), (d) or (k) hereof after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.”  Holdings shall deliver to the Trustee, within five Business Days after the occurrence thereof, written notice in the form of an Officers’ Certificate of any event which is, or with the giving of notice or the lapse of time or both would become, an Event of Default, its status and what action the Issuers are taking or propose to take with respect thereto.

The term “Bankruptcy Law” means ▇▇▇▇▇ ▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇ Code, or any similar Federal or state law for the relief of debtors.  The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law.

SECTION 6.02              Acceleration.  If an Event of Default (other than an Event of Default specified in Section 6.01(f) or (g) hereof with respect to Holdings) occurs with respect to the Notes and is continuing, the Trustee, by written notice to the Issuers or the holders of at least 30% in aggregate principal amount of outstanding Notes by written notice to the Issuers, with a copy to the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately. If an Event of Default specified in Section 6.01(f) or (g) with respect to Holdings occurs, the principal of, premium, if any, and interest on all the Notes will become immediately due and payable without any declaration or other act on the part of the Trustee or any holders. The holders of a majority in principal amount of outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences if the Event of Default giving rise to such acceleration has been cured or waived.

In the event of any Event of Default specified in Section 6.01(e), such Event of Default and all consequences thereof (excluding, however, any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the holders of the Notes, if within 20 days after such Event of Default arose the Issuers deliver an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis

99

for such Event of Default has been discharged or (y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (z) the default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the principal amount of the Notes as described above be annulled, waived or rescinded upon the happening of any such events.

SECTION 6.03              Other Remedies.  If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes, this Indenture or the Security Documents.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding.  A delay or omission by the Trustee or any holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default.  No remedy is exclusive of any other remedy.  To the extent required by law, all available remedies are cumulative.

SECTION 6.04              Waiver of Past Defaults.  Provided the Notes are not then due and payable by reason of a declaration of acceleration, the holders of a majority in principal amount of the Notes by written notice to the Trustee may waive an existing Default and its consequences except (a) a Default in the payment of the principal of or interest on a Note, (b) a Default arising from the failure to redeem or purchase any Note when required pursuant to the terms of this Indenture or (c) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each holder affected.  The Issuers shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of holders have consented to such waiver and attaching evidence of such consents.  When a Default is waived, it is deemed cured and the Issuers, the Trustee and the holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05              Control by Majority.  The holders of at least a majority in aggregate principal amount of Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.  However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, if the Trustee, being advised by counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith shall determine that the action or proceeding so directed would involve the Trustee in personal liability or expense for which it is not adequately indemnified, or subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such holders) or that would involve the Trustee in personal liability.  Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

100

SECTION 6.06              Limitation on Suits.

(a)                                 Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no holder may pursue any remedy with respect to this Indenture or the Notes unless:

(i)                                     such holder has previously given the Trustee written notice that an Event of Default is continuing,

(ii)                                  holders of at least 30% in aggregate principal amount of the outstanding Notes have requested the Trustee in writing to pursue the remedy,

(iii)                               such holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense,

(iv)                              the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity, and

(v)                                 the holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

(b)                                 A holder may not use this Indenture to prejudice the rights of another holder or to obtain a preference or priority over another holder.

SECTION 6.07              Contractual Rights of the Holders to Receive Payment.  Notwithstanding any other provision of this Indenture, the contractual right of any holder to receive payment of principal of and interest on the Note held by such holder, on or after the respective due dates thereof, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such holder.

SECTION 6.08              Collection Suit by Trustee.  If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuers or any other obligor on the Notes for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in the Notes) and the amounts provided for in Section 7.07.

SECTION 6.09              Trustee May File Proofs of Claim.  The Trustee may file such proofs of claim, statements of interest and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the holders allowed in any judicial proceedings relative to the Issuer, the Subsidiary Guarantors, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments

101

directly to the holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. 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.  Subject to the terms of the Intercreditor Agreements and the Security Documents, any money or property collected by the Trustee pursuant to this Article VI and any other money or property distributable in respect of the Issuers’ or any Subsidiary Guarantor’s obligations under this Indenture after an Event of Default shall be applied in the following order:

FIRST:  to the Trustee and Notes Collateral Agent for amounts due hereunder and under the Security Documents;

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

THIRD:  to the Issuers or, to the extent the Trustee collects any amount for any Subsidiary Guarantor, to such Subsidiary Guarantor.

The Trustee may fix a record date and payment date for any payment to the holders pursuant to this Section 6.10.  At least 15 days before such record date, the Trustee shall mail to each holder and the Issuers a notice that states the record date, the payment date and the amount to be paid.

SECTION 6.11              Undertaking for Costs.  In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and 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 Article VI does not apply to a suit by the Trustee, a suit by a holder pursuant to Section 6.07 or a suit by holders of more than 10% in principal amount of the Notes.

SECTION 6.12              Waiver of Stay or Extension Laws.  Neither the Issuers nor any Subsidiary Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuers and the Subsidiary Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the

102

Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

ARTICLE VII

TRUSTEE

SECTION 7.01              Duties of Trustee.

(a)                                 The Trustee, prior to the occurrence of an Event of Default with respect to the Notes and after the curing or waiving of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture.  If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

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

(i)                                     the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee (it being agreed that the permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty); and

(ii)                                  in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture.  The Trustee shall be under no duty to make any investigation as to any statement contained in any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions.  However, in the case of certificates or opinions required by any provision hereof to be provided to it, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

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

(i)                                     this paragraph does not limit the effect of paragraph (b) of this Section;

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

(iii)                               the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05; and

103

(iv)                              no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise Incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers.

(d)                                 Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

(e)                                  The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer.

(f)                                   Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g)                                  Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01(c).

SECTION 7.02              Rights of Trustee.

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

(b)                                 Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both.  The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

SECTION 7.03              Individual Rights of Trustee.  The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or their Affiliates with the same rights it would have if it were not Trustee.  The Notes Collateral Agent, any Paying Agent or Registrar may do the same with like rights.  However, the Trustee must comply with Section 7.10 and 7.11.

SECTION 7.04              Trustee’s Disclaimer.  The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Subsidiary Guarantees or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuers or any Subsidiary Guarantor in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Trustee’s certificate of authentication.  The Trustee shall not be charged with knowledge of any Default or Event of Default under ▇▇▇▇▇▇▇▇  ▇.▇▇(▇), (▇), (▇), (▇), (▇), (▇), (▇), (▇) or (k) or of the identity of any Significant Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have received written notice thereof in accordance with Section 14.02 hereof from the Issuers, any Subsidiary Guarantor or any holder.  In accepting the trust hereby created, the Trustee acts solely as Trustee under this Indenture and not in its individual capacity and all persons, including without limitation the holders of Notes and the Issuers having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for payment except as otherwise provided herein.

SECTION 7.05              Notice of Defaults.  If a Default occurs and is continuing and is actually known to a Trust Officer of the Trustee, the Trustee shall mail, or delivery electronically if held by the Depository, to each holder of the Notes notice of the Default within the later of 90 days after it occurs or 30 days after it is actually known to a Trust Officer or written notice of it is received by the Trustee at the Corporate Trust Officer of the Trustee from the Issuers, any Subsidiary Guarantor or any holder.  Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Note, the Trustee may withhold notice if and so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interests of the noteholders.  Holdings is required to deliver to the Trustee, annually, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. Holdings also is required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any event which would constitute certain Defaults, their status and what action Holdings is taking or proposes to take in respect thereof.

SECTION 7.06              [Intentionally Omitted].

SECTION 7.07              Compensation and Indemnity.  The Issuers and the Subsidiary Guarantors, jointly and severally, shall pay to the Trustee from time to time compensation for the Trustee’s acceptance of this Indenture and its services hereunder.  The

106

Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust.  The Issuers and the Subsidiary Guarantors, jointly and severally, shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances Incurred or made by it, including costs of collection, in addition to the compensation for its services.  Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts.  The Issuers and the Subsidiary Guarantors, jointly and severally, shall indemnify the Trustee or any predecessor Trustee and their directors, officers, employees and agents against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees, disbursements and expenses and including taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) Incurred by or in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture or Subsidiary Guarantee against any Issuer or any Subsidiary Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by any Issuer, any Subsidiary Guarantor, any holder or any other Person).  The obligation to pay such amounts shall survive the payment in full or defeasance of the Notes or the removal or resignation of the Trustee.  The Trustee shall notify the Issuers of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuers shall not relieve any Issuer or any Subsidiary Guarantor of its indemnity obligations hereunder.  The Issuers shall defend the claim and the indemnified party shall provide reasonable cooperation at the Issuers’ expense in the defense.  Such indemnified parties may have separate counsel and the Issuers and such Subsidiary Guarantor, as applicable, shall pay the fees, disbursements and expenses of such counsel; provided, however, that the Issuers shall not be required to pay such fees, disbursements and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no actual or potential conflict of interest between the Issuers and the Subsidiary Guarantor, as applicable, and such parties in connection with such defense.  The Issuers need not reimburse any expense or indemnify against any loss, liability or expense Incurred by an indemnified party through such party’s own willful misconduct, negligence or bad faith.

To secure the Issuers’ and the Subsidiary Guarantors’ payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Notes.

The Issuers’ and the Subsidiary Guarantors’ payment obligations pursuant to this Section 7.07 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the Trustee.  Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee Incurs expenses (including the charges and expenses of the Trustee’s agents and counsel) after the occurrence of a Default specified in Section 6.01(f) or (g) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise Incur any financial liability in the performance of any of its duties hereunder,

107

or in the exercise of any of its rights or powers, if repayment of such funds or adequate indemnity against such risk or liability is not assured to its satisfaction.

(d)                                 If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the holders of 10% in principal amount of the 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 fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in Section 310(b) of the TIA, any holder who has been a bona fide holder of a Note for at least six months may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee.

109
