If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 3.2(c)(2) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 3.2(g) hereof, and the Company will execute and the Trustee will authenticate and deliver to the person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 3.2(d) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depository and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the persons in whose names such Notes are so registered.

(e)    Transfer and Exchange of Definitive Notes for Beneficial Interests in Global Notes. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee will cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

13

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to the previous paragraph at a time when a Global Note has not yet been issued, the Company will issue and, upon receipt of an Authentication Order in accordance with Section 3.2 hereof, the Trustee will authenticate one or more Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

(f)    Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 3.2(f), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder will present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by his attorney, duly authorized in writing. A Holder of Definitive Notes may transfer such Notes to a person who takes delivery thereof in the form of a Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Definitive Notes pursuant to the instructions from the Holder thereof.

(g)    Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note will be returned to or retained and canceled by the Trustee in accordance with Section 2.12 of the Base Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note will be reduced accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note will be increased accordingly and an endorsement will be made on such Global Note by the Trustee or by the Depository at the direction of the Trustee to reflect such increase.

Section 3.3    General Provisions Relating to Transfers and Exchanges.

(a)    To permit registrations of transfers and exchanges, the Company will execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 3.2 hereof or at the Registrar’s request.

(b)    No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.11 and 9.6 of the Base Indenture and Section 4.3 hereof).

14

(c)    The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

(d)    All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(e)    Neither the Registrar nor the Company will be required:

(i) to issue, register the transfer of or to exchange any Note during a period beginning at the opening of business fifteen (15) days before any selection of Notes for redemption under Article IV hereof and ending at the close of business on the earliest date on which the relevant notice of redemption is deemed to have been given to all Holders of Notes to be so redeemed; or

(ii) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

(iii) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date.

(f)    Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

(g)    The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of Section 2.3 of the Base Indenture.

(h)    All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 3.3 to effect a registration of transfer or exchange may be submitted by facsimile.

(j)    In connection with any proposed transfer outside the book entry system, there shall be provided to the Trustee all information necessary to allow the Trustee to

15

comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on the information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

ARTICLE IV

REDEMPTION OF NOTES

The provisions of Article III of the Base Indenture, as amended by the provisions of this Fourth Supplemental Indenture, shall apply to the Notes.

Section 4.1    Optional Redemption of Notes.

The Company may redeem on any one or more occasions some or all of the Notes before they mature. The redemption price (the “Redemption Price”) will equal the sum of (1) an amount equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest up to, but not including, the Redemption Date and (2) a Make-Whole Premium; provided that, the Company will not redeem the Notes on any date if the principal amount of the Notes has been accelerated, and such an acceleration has not been rescinded or cured on or prior to such date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to the Notes to be redeemed). Notwithstanding the foregoing, if the Notes are redeemed on or after April 1, 2029, the Redemption Price will not include a Make-Whole Premium; provided further that if the Redemption Date falls after a Record Date and on or prior to the corresponding interest payment date, the Company will pay the full amount of accrued and unpaid interest, if any, on such interest payment date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Notes for redemption) and the Redemption Price shall not include accrued and unpaid interest up to, but not including, the Redemption Date.

Section 4.2    Notice of Optional Redemption, Selection of Notes.

(a)    In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 4.1, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than five (5) Business Days prior (or such shorter period of time as may be acceptable to the Trustee) to the date the notice of redemption is to be sent, the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed, or sent by electronic transmission a notice of such redemption not fewer than fifteen (15) calendar days nor more than sixty (60) calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed in whole or in part at its last address as the same appears on the Register; provided that if the Company makes such request of the Trustee, it shall, together with such request, also give written notice of the Redemption Date to the Trustee, provided further that the text of the notice shall be prepared by the Company. Such mailing shall be by first class mail or sent by electronic transmission. The notice, if sent in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such

16

notice by mail or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Concurrently with the sending of any such notice of redemption, the Company shall issue a press release announcing such redemption, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the redemption notice or any of the proceedings for the redemption of any Note called for redemption.

(b)    Each such notice of redemption shall specify: (i) the aggregate principal amount of Notes to be redeemed, (ii) the CUSIP number or numbers of the Notes being redeemed, (iii) the Redemption Date (which shall be a Business Day), (iv) the Redemption Price at which Notes are to be redeemed, (v) the place or places of payment and that payment will be made upon presentation and surrender of such Notes and (vi) that interest accrued and unpaid to, but excluding, the Redemption Date will be paid as specified in said notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that, on and after the Redemption Date, upon surrender of such Note, a new Note or Note in principal amount equal to the unredeemed portion thereof will be issued.

(c)    On or prior to the Redemption Date specified in the notice of redemption given as provided in this Section 4.2, the Company will deposit with the Paying Agent (or, if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 2.5 of the Base Indenture) an amount of money in immediately available funds sufficient to redeem on the Redemption Date all the Notes (or portions thereof) so called for redemption at the appropriate Redemption Price; provided that if such payment is made on the Redemption Date, it must be received by the Paying Agent, by 11:00 a.m., New York City time, on such date. The Company shall be entitled to retain any interest, yield or gain on amounts deposited with the Paying Agent pursuant to this Section 4.2 in excess of amounts required hereunder to pay the Redemption Price.

(d)    If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Notes or the Notes in certificated form to be redeemed (in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate in accordance with the Applicable Procedures. The Notes (or portions thereof) so selected for redemption shall be deemed duly selected for redemption for all purposes hereof.

Section 4.3    Payment of Notes Called for Redemption by the Company.

(a)    If notice of redemption has been given as provided in Section 4.2, the Notes or portion of Notes with respect to which such notice has been given shall become

17

due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Company shall default in the payment of such Notes at the Redemption Price, interest on the Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date and, on and after the Redemption Date (unless the Company shall default in the payment of the Redemption Price) such Notes shall cease to be entitled to any benefit or security under the Indenture, and the Holders thereof shall have no right in respect of such Notes except the right to receive the Redemption Price thereof. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Company at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date.

(b)    Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

ARTICLE V

GUARANTEE

This Article V shall replace Article XII of the Base Indenture with respect to the Notes only.

Section 5.1    Note Guarantee.

By its execution hereof, the Guarantor acknowledges and agrees that the Notes shall be entitled to the benefits of a Guarantee. Accordingly, subject to the provisions of this Article, the Guarantor hereby unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and its successors and assigns that: (i) the principal of (including the Redemption Price upon redemption pursuant to Article IV), premium, if any, and interest, if any, on the Notes shall be duly and punctually paid in full when due, whether at the Stated Maturity, upon acceleration, upon redemption or otherwise, and interest on overdue principal, premium, if any, and (to the extent permitted by law) interest on any interest, if any, on the Notes and all other obligations of the Company to the Holders or the Trustee hereunder or under the Notes (including fees, expenses or other) shall be promptly paid in full or performed, all in accordance with the terms hereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Stated Maturity, by acceleration, call for redemption or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in this Article (collectively, the “Guarantee Obligations”).

18

Subject to the provisions of this Article, the Guarantor hereby agrees that its Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any thereof, the entry of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Guarantor. The Guarantor hereby waives and relinquishes: (a) any right to require the Trustee, the Holders or the Company (each, a “Benefited Party”) to proceed against the Company or any other person or to proceed against or exhaust any security held by a Benefited Party at any time or to pursue any other remedy in any secured party’s power before proceeding against the Guarantor; (b) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other person or persons or the failure of a Benefited Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other person or persons; (c) demand, protest and notice of any kind (except as expressly required by the Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional indebtedness or obligation or of any action or non-action on the part of the Guarantor, the Company, any Benefited Party, any creditor of the Guarantor or the Company or on the part of any other person whomsoever in connection with any obligations the performance of which are hereby guaranteed; (d) any defense based upon an election of remedies by a Benefited Party, including but not limited to an election to proceed against the Guarantor for reimbursement; (e) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (f) any defense arising because of a Benefited Party’s election, in any proceeding instituted under the Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Code; and (g) any defense based on any borrowing or grant of a security interest under Section 364 of the Bankruptcy Code. The Guarantor hereby covenants that, except as otherwise provided therein, the Guarantee shall not be discharged except by payment in full of all Guarantee Obligations, including the principal, premium, if any, and interest on the Notes and all other costs provided for under the Indenture.

If any Holder or the Trustee is required by any court or otherwise to return to either the Company or the Guarantor, or any trustee or similar official acting in relation to either the Company or the Guarantor, any amount paid by the Company or the Guarantor to the Trustee or such Holder, the Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. The Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. The Guarantor agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI of the Base Indenture for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article VI of the Base Indenture, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of the Guarantee.

19

Section 5.2    Execution and Delivery of Note Guarantee.

(a)    To evidence the Guarantee set forth in Section 5.1 hereof, the Guarantor agrees that a Notation of Guarantee substantially in the form included in Exhibit B hereto shall be endorsed on each Note authenticated and delivered by the Trustee and that this Fourth Supplemental Indenture shall be executed on behalf of the Guarantor by an Officer of the Guarantor.

(b)    The Guarantor agrees that the Guarantee set forth in this Article V shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse on each Note a notation of the Guarantee.

(c)    If an Officer whose facsimile signature is on a Note or a notation of Guarantee no longer holds that office at the time the Trustee authenticates the Note on which the Guarantee is endorsed, the Guarantee shall be valid nevertheless.

(d)    The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Fourth Supplemental Indenture on behalf of the Guarantor.

Section 5.3    Limitation of Guarantor’s Liability; Certain Bankruptcy Events.

(a)    The Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee Obligations of the Guarantor pursuant to its Note Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, the Holders and the Guarantor hereby irrevocably agree that the Guarantee Obligations of the Guarantor under this Article V shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the Guarantor, result in the Guarantee Obligations of the Guarantor under the Note Guarantee not constituting a fraudulent transfer or conveyance.

(b)    The Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the event of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company, the Guarantor shall not file (or join in any filing of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to prohibit (even temporarily) execution on the Note Guarantee and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or 105 of the Bankruptcy Law or otherwise.

Section 5.4    Application of Certain Terms and Provisions to the Guarantor.

(a)    For purposes of any provision of the Indenture which provides for the delivery by the Guarantor of an Officers’ Certificate and/or an Opinion of Counsel, the definitions of such terms in Section 1.2 hereof shall apply to the Guarantor as if references therein to the Company or the Guarantor, as applicable, were references to the Guarantor.

20

(b)    Any notice or demand which by any provision of the Indenture is required or permitted to be given or served by the Trustee or by the Holders of Notes to or on the Guarantor may be given or served as described in Section 10.2 of the Base Indenture as if references therein to the Company were references to the Guarantor.

(c)    Upon any demand, request or application by the Guarantor to the Trustee to take any action under the Indenture, the Guarantor shall furnish to the Trustee such certificates and opinions as are required in Section 10.1 hereof as if all references therein to the Company were references to the Guarantor.

ARTICLE VI

ADDITIONAL COVENANTS

The following additional covenants shall apply with respect to the Notes so long as any of the Notes remain outstanding:

Section 6.1    Maintenance of Office or Agency.

The Company will maintain an office or agency in the United States where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or redemption and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. As of the date of the Indenture, such office shall be the Corporate Trust Office and, at any other time, at such other address as the Trustee may designate from time to time by notice to the Company. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office.

The Company may also from time to time designate co-registrars and one or more 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. The Company will 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.

The Company hereby initially designates the Trustee as Paying Agent, Registrar and the Corporate Trust Office shall be considered as one such office or agency of the Company for each of the aforesaid purposes.

Section 6.2    Appointments to Fill Vacancies in Trustee’s Office.

The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, upon the terms and conditions and otherwise as provided in Section 7.8 of the Base Indenture, a Trustee, so that there shall at all times be a Trustee hereunder.

21

Section 6.3    Reports.

(a)    Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Company will furnish to the Holders of Notes or cause the Trustee to furnish to the Holders of Notes, within the time periods specified in the SEC’s rules and regulations:

(i)    all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Company were required to file such reports; and

(ii)    all current reports that would be required to be filed with the SEC on Form 8-K if the Company were required to file such reports.

All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Company’s Consolidated Financial Statements by its independent registered public accounting firm. In addition, the Company shall file a copy of each of the reports referred to above with the SEC for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the SEC will not accept such a filing) and will make the reports available on the Company’s website within those time periods. Delivery of reports, information and documents to the Trustee under Section 6.3 is for informational purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). Notwithstanding the foregoing, the Company and the Guarantor may satisfy their obligation to furnish reports pursuant to this Section 6.3 by furnishing, or filing with the SEC for public availability, reports of the Company and the Guarantor within the time periods specified in the SEC’s rules and regulations.

(b)    If the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company will nevertheless continue filing the reports specified in the preceding paragraph with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Company will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will make the reports referred to in the preceding paragraph available on its website within the time periods that would apply if the Company were required to file those reports with the SEC.

Section 6.4    Limitations on Incurrence of Debt.

(a)    The Company will not, and will not permit any of its Subsidiaries to, Incur any Indebtedness, other than Intercompany Indebtedness and guarantees of Indebtedness Incurred by the Company or any of its Subsidiaries in compliance with the Indenture, if, immediately after giving effect to the Incurrence of such Indebtedness and the application of the proceeds thereof, Total Outstanding Debt would be greater than 60% of Total Assets as of the end of the fiscal quarter covered in the Company’s annual or quarterly report most recently furnished to Holders of the Notes or filed with the SEC, as the case may be.

22

(b)    The Company will not, and will not permit any of its Subsidiaries to, Incur any Secured Debt, other than guarantees of Secured Debt Incurred by the Company or any of its Subsidiaries in compliance with the Indenture, if, immediately after giving effect to the Incurrence of such Secured Debt and the application of the proceeds thereof, the aggregate principal amount of Secured Debt would be greater than 40% of Total Assets as of the end of the fiscal quarter covered in the Company’s annual or quarterly report most recently furnished to Holders of the Notes or filed with the SEC, as the case may be.

(c)    The Company and its Subsidiaries will at all times maintain Total Unencumbered Assets of not less than 150% of the aggregate outstanding principal amount of Unsecured Debt.

(d)    The Company will not, and will not permit any of its Subsidiaries to, Incur any Indebtedness other than Intercompany Indebtedness and guarantees of Indebtedness Incurred by the Company or any of its Subsidiaries in compliance with the Indenture, if the ratio of Consolidated EBITDA to Interest Expense for the most recent quarterly period covered in the Company’s annual or quarterly report most recently furnished to holders of the Notes or filed with the SEC, as the case may be and in accordance with Section 6.3 hereof, prior to such time, annualized (i.e., multiplied by four (4)) prior to the date on which such additional Indebtedness is to be Incurred shall have been less than 1.50:1.00 on a pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that:

(i)    such Indebtedness and any other Indebtedness Incurred by the Company and its Subsidiaries since the first day of such quarterly period and the application of the proceeds therefrom, including to refinance other Indebtedness, had occurred at the beginning of such period;

(ii)    the repayment or retirement of any Indebtedness (other than Indebtedness repaid or retired with the proceeds of any other Indebtedness, which repayment or retirement shall be calculated pursuant to the preceding clause (i)) by the Company and its Subsidiaries since the first day of such quarterly period had been repaid or retired at the beginning of such period (except that, in making such computation, the amount of Indebtedness under any revolving credit facility shall be computed based upon the average daily balance of such Indebtedness during such period);

(iii)    in the case of Acquired Indebtedness or Indebtedness Incurred in connection with any acquisition since the first day of such quarterly period, the related acquisition had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition being included in such pro forma calculation; and

23

(iv)    in the case of any acquisition or disposition of any asset or group of assets or the placement of any assets in service or removal of any assets from service by the Company or any of its Subsidiaries from the first day of such quarterly period to the date of determination, including, without limitation, by merger, or stock or asset purchase or sale, the acquisition, disposition, placement in service or removal from service had occurred as of the first day of such period, with appropriate adjustments to Interest Expense with respect to the acquisition, disposition, placement in service or removal from service being included in that pro forma calculation.

Section 6.5    Maintenance of Properties.

The Company shall cause all of its material properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order, casualty and condemnation excepted (and the Company may take out of service for a period of time, any of its properties that have been condemned or suffered any loss due to casualty in order to make such repairs, betterments and improvements), all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, notwithstanding anything herein to the contrary, (i) the Company may discontinue the maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the conduct of its business or the business of any Consolidated Subsidiary and not disadvantageous in any material respect to the Holders, and (ii) the Company and its Subsidiaries may sell or otherwise dispose of any of their properties for value in the ordinary course of business.

Section 6.6    Insurance.

The Company shall cause each of its properties and each of the properties of its Subsidiaries to be insured against loss of damage with insurers of recognized responsibility, in commercially reasonable amounts and types as determined by the Company and with insurers of recognized responsibility.
