THE SECURITIES

SECTION 2.01. Amount of Securities; Issuable in Series. The aggregate principal amount of Original Securities which may be authenticated and delivered under this Indenture on the Issue Date is $350,000,000. The Securities may be issued in one or more series. All Securities of any one series shall be substantially identical except as to denomination.

The Company may from time to time after the Issue Date issue Additional Securities under this Indenture in an unlimited principal amount, so long as (i) the Incurrence of the Indebtedness represented by such Additional Securities is at such time permitted by Section 4.03 and (ii) such Additional Securities are issued in compliance with the other applicable provisions of this Indenture. With respect to any Additional Securities issued after the Issue Date (except

-38-

for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities pursuant to Sections 2.07, 2.08, 2.09, 2.10, 3.08, 4.06(g), 4.08(c) or the Appendix), there shall be (a) established in or pursuant to a resolution of the Board of Directors of the Company and (b) (i) set forth or determined in the manner provided in an Officers’ Certificate or (ii) established in one or more indentures supplemental hereto, prior to the issuance of such Additional Securities:

(1) whether such Additional Securities shall be issued as part of a new or existing series of Securities and the title of such Additional Securities (which shall distinguish the Additional Securities of the series from Securities of any other series);

(2) the aggregate principal amount of such Additional Securities which may be authenticated and delivered under this Indenture;

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

(4) if applicable, that such Additional Securities shall be issuable in whole or in part in the form of one or more Global Securities and, in such case, the respective depositaries for such Global Securities, the form of any legend or legends which shall be borne by such Global Securities 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 the Appendix in which any such Global Security may be exchanged in whole or in part for Additional Securities registered, or any transfer of such Global Security in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Security or a nominee thereof; and

(5) if applicable, that such Additional Securities that are not Transfer Restricted Definitive Securities shall not be issued in the form of Initial Securities as set forth in Exhibit A, but shall be issued in the form of Exchange Securities as set forth in Exhibit B.

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

SECTION 2.02. Form and Dating. Provisions relating to the Initial Securities and the Exchange Securities are set forth in the Appendix, which is hereby incorporated in and expressly made a part of this Indenture. The Initial Securities and the Authentication Agent’s certificate of authentication, and any Additional Securities (if issued as Transfer Restricted Definitive Securities) and the Authentication Agent’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 Exchange Securities and the Authentication Agent’s certificate of authentication, and any Additional Securities issued other than as Transfer Restricted

-39-

Definitive Securities and the Authentication Agent’s certificate of authentication, shall each be substantially in the form of Exhibit B hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company or any Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Security shall be dated the date of its authentication. The Securities shall be issuable only in registered form without interest coupons and only in denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

SECTION 2.03. Execution and Authentication. The Authentication Agent shall authenticate and make available for delivery upon a written order of the Company signed by one Officer (a) Original Securities for original issue on the date hereof in an aggregate principal amount of $350,000,000, (b) subject to the terms of this Indenture, Additional Securities in an aggregate principal amount to be determined at the time of issuance and specified therein and (c) the Exchange Securities for issue in a Registered Exchange Offer pursuant to the Registration Rights Agreement for a like principal amount of Initial Securities exchanged pursuant thereto or otherwise pursuant to an effective registration statement under the Securities Act. Such order shall specify the amount of the Securities to be authenticated, the date on which the original issue of Securities is to be authenticated and whether the Securities are to be Initial Securities or Exchange Securities. Notwithstanding anything to the contrary in the Indenture or the Appendix, any issuance of Additional Securities after the Issue Date shall be in a principal amount of at least $2,000 and any integral multiples of $1,000 in excess thereof, whether such Additional Securities are of the same or a different series than the Original Securities.

One Officer shall sign the Securities for the Company by manual or facsimile signature.

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

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

The Authentication Agent may appoint one or more authenticating agents reasonably acceptable to the Company to authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Authentication Agent 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.

-40-

SECTION 2.04. Registrar and Paying Agent.

(a) The Company shall maintain (i) an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) an office or agency in the United States where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company 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 Company initially appoints Deutsche Bank Trust Company Americas as (i) Registrar and Paying Agent in connection with the Securities and (ii) the Securities Custodian with respect to the Global Securities.

(b) The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails 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. The Company or any of its domestically organized Subsidiaries may act as Paying Agent or Registrar.

(c) The Company 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 as evidenced by an appropriate agreement entered into by the Company 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 Company 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. Prior to 10:00 a.m., New York City time, on each due date of the principal of and interest on any Security, the Company shall deposit with each Paying Agent (or if the Company 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 Company 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 Securities, and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Wholly Owned Subsidiary of the Company 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 Company 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. During the continuance of an Event of Default under this Indenture, the Trustee may require a Paying Agent to pay all money held by it to the Trustee.

-41-

Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as 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 Registrar 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 Paying Agent is not the same entity as the Registrar, the Company shall furnish, or cause the Registrar to furnish, to the Paying Agent, in writing at least five Business Days before each interest payment date and at such other times as the Paying Agent may request in writing, a list in such form and as of such date as the Paying Agent may reasonably require of the names and addresses of Holders.

SECTION 2.07. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with the Appendix. When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Securities are presented to the Registrar with a request to exchange them for an equal principal amount of Securities 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 Company shall execute and the Authentication Agent shall authenticate Securities at the Registrar’s request. The Company 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 2.07 (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Section 3.08, 4.06, 4.08 or 9.05). The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) or of any Securities for a period of 15 days before a selection of Securities to be redeemed.

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

Any Holder of a beneficial interest in a Global Security shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any Holder of a beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required to be reflected in a book entry.

-42-

All Securities 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 Securities surrendered upon such transfer or exchange.

SECTION 2.08. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall issue and the Authentication Agent shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) notifies the Company or the Registrar 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 Company or the Registrar prior to the Security 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 Registrar. If required by the Registrar, Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of (i) the Registrar or Trustee to protect the Registrar or Trustee or (ii) the Company, to protect the Company, the Trustee, the Paying Agent and the Registrar, from any loss that any of them may suffer if a Security is replaced. The Company, the Registrar and the Trustee may charge the Holder for their expenses in replacing a Security (including, without limitation, attorneys’ fees and disbursements in replacing such Security). In the event any such Security has become or is about to become due and payable, the Company in its discretion may direct the Registrar to pay the same without surrender thereof upon the Holder furnishing the Company and the Registrar with indemnity satisfactory to them and complying with such other reasonable regulations as the Company may prescribe and paying such reasonable expense as the Company and the Registrar may incur in connection therewith.

Every replacement Security is an additional obligation of the Company.

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 Securities.

SECTION 2.09. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Authentication Agent except for those canceled by it or the Registrar, those delivered to it for cancellation and those described in this Section 2.09 as not outstanding. Subject to Section 13.06, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

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

If the 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

-43-

on that date with respect to the Securities (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 Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10. Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Company may prepare and the Authentication Agent shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Authentication Agent shall authenticate Definitive Securities and make them available for delivery in exchange for temporary Securities upon surrender of such temporary Securities at the office or agency of the Company, without charge to the Holder. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as Definitive Securities.

SECTION 2.11. Cancellation. The Company at any time may deliver Securities to the Registrar for cancellation. Any person other than the Registrar shall forward to the Registrar any Securities surrendered to them for registration of transfer, exchange or payment. The Registrar and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Securities in accordance with its customary procedures (subject to the record retention requirements of the Exchange Act) or deliver copies of canceled Securities to the Company pursuant to written direction by an Officer of the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Registrar for cancellation. The Authentication Agent shall not authenticate Securities in place of canceled Securities other than pursuant to the terms of this Indenture.

SECTION 2.12. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay the defaulted interest then borne by the Securities (plus interest on such defaulted interest to the extent lawful), in any lawful manner. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and Registrar and shall promptly mail or cause to be mailed to each affected Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 2.13. CUSIP Numbers, ISINs, etc. The Company in issuing the Securities may use CUSIP numbers, ISINs and “Common Code” numbers (if then generally in use) and, if so, the Registrar shall use 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 Securities or as contained in any notice of a redemption, that reliance may be placed only on the other identification numbers printed on the Securities and that any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee

-44-

and Registrar in writing of any change in the CUSIP numbers, ISINs and “Common Code” numbers.

SECTION 2.14. Calculation of Specified Percentage of Securities. 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 Securities, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Securities, the Holders of which have so consented by (b) the aggregate principal amount, as of such date of determination, of the Securities then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.09 and Section 13.06 of this Indenture. Any such calculation made pursuant to this Section 2.14 shall be made by the Company and delivered to the Trustee and the Registrar pursuant to an Officers’ Certificate.

ARTICLE 3

REDEMPTION

SECTION 3.01. Redemption. Subject to the conditions and at the redemption prices set forth in Paragraph 5 of the form of Securities set forth in Exhibit A and Exhibit B hereto, which are hereby incorporated by reference and made a part of this Indenture, the Securities may be redeemed, in whole, or from time to time in part, together with accrued and unpaid interest to the redemption date.

SECTION 3.02. Applicability of Article. Redemption of Securities at the election of the Company or otherwise, as permitted or required by any provision of this Indenture, shall be made in accordance with such provision and this Article 3.

SECTION 3.03. Notices to Trustee. If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraph 5 of the applicable Security, it shall notify the Trustee and Registrar in writing of (i) the Section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Securities to be redeemed and (iv) the redemption price. If the redemption is made pursuant to paragraph 5 of the applicable Security, the Company shall give notice to the Trustee and Registrar provided for in this paragraph at least 40 days but not more than 60 days before the date of such redemption unless a shorter period is acceptable to the Trustee and Registrar. Such notice shall be accompanied by an Officers’ Certificate and Opinion of Counsel from the Company to the effect that such redemption will comply with the conditions herein. If fewer than all the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and given in writing to the Trustee and Registrar, which record date shall be not fewer than 15 days after the date of notice to the Trustee and Registrar. Any such notice may be canceled at any time prior to notice of such redemption being sent to any Holder and shall thereby be void and of no effect.

-45-

SECTION 3.04. Selection of Securities to Be Redeemed. In the case of any partial redemption, selection of the Securities for redemption will be made by the Registrar in compliance with the requirements of the principal national securities exchange, if any, on which such Securities are listed, or if such Securities are not so listed, by lot or by such other method as the Registrar shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that, to the extent practicable, the Registrar shall not select Securities for redemption which would result in a Holder of Securities having a principal amount of Securities less than the minimum denomination. The Registrar shall make the selection from outstanding Securities not previously called for redemption. The Registrar may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the Registrar selects shall be in amounts of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Registrar shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

SECTION 3.05. Notice of Optional Redemption.

(a) At least 30 days but not more than 60 days before the date of redemption of Securities pursuant to Paragraph 5 of the applicable Security, the Company shall mail or cause to be mailed by first-class mail a notice of redemption to the registered address of each Holder whose Securities are to be redeemed or otherwise in accordance with the procedures of the Depository.

Any such notice shall identify the Securities to be redeemed and shall state:

(i) the redemption date;

(ii) the redemption price and the amount of accrued and unpaid interest to the redemption date;

(iii) the name and address of a Paying Agent;

(iv) that Securities called for redemption must be surrendered to a Paying Agent to collect the redemption price, plus accrued and unpaid interest;

(v) if fewer than all the outstanding Securities are to be redeemed, the certificate numbers and principal amounts of the particular Securities to be redeemed, the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial redemption;

(vi) that, unless the Company defaults in making such redemption payment or any Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption date;

-46-

(vii) the CUSIP number, ISIN and/or “Common Code” number, if any, printed on the Securities being redeemed; and

(viii) that no representation is made as to the correctness or accuracy of the CUSIP number or ISIN and/or “Common Code” number, if any, listed in such notice or printed on the Securities.

In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice of redemption shall describe each such condition, and if applicable, shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the stated redemption date, or by the redemption date as so delayed.

(b) At the Company’s request, the Registrar shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company has delivered to the Trustee and Registrar, at least 45 days (unless a shorter period is acceptable to the Trustee and Registrar) prior to the redemption date, an Officers’ Certificate requesting that the Registrar give such notice. In such event, the Company shall provide the Registrar in writing with the information required by this Section 3.05.

SECTION 3.06. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.05, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice (except to the extent such redemption is conditional as set forth in Section 3.05). Upon surrender to any Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued and unpaid interest to the redemption date; provided, however, that if the redemption date is after a regular record date and on or prior to the interest payment date, the accrued interest shall be payable to the Holder of the redeemed Securities registered on the relevant record date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder or the validity of the redemption.

SECTION 3.07. Deposit of Redemption Price. Prior to 10:00 a.m., New York City time, on the redemption date, the Company shall deposit with the Paying Agent (or, if the Company or a Wholly Owned Subsidiary is a Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities or portions thereof to be redeemed on that date other than Securities or portions of Securities called for redemption that have been delivered by the Company to the Registrar for cancellation. On and after the redemption date, interest shall cease to accrue on Securities or portions thereof called for redemption so long as the Company has deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Securities to be redeemed, unless a Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture.

SECTION 3.08. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Authentication Agent shall authenticate

-47-

for the Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

ARTICLE 4

COVENANTS

SECTION 4.01. Payment of Securities. The Company shall promptly pay the principal of and interest, on the Securities on the dates and in the manner provided in the Securities and in this Indenture. An installment of principal of or interest shall be considered paid on the date due if on such date the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due and the Paying Agent is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate borne by the Securities to the extent lawful.

SECTION 4.02. Reports and Other Information. Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, the Company shall file with the SEC (and provide the Trustee and Holders with copies thereof, without cost to each Holder, within 15 days after it files them with the SEC),

(a) within 90 days after the end of each fiscal year (or such longer period as may be permitted by the SEC if the Company were then subject to such SEC reporting requirements as a required filer, voluntary filer or otherwise), annual reports on Form 10-K (or any successor or comparable form) containing the information required to be contained therein (or required in such successor or comparable form),

(b) within 45 days after the end of each of the first three fiscal quarters of each fiscal year (or such longer period as may be permitted by the SEC if the Company were then subject to such SEC reporting requirements as a required filer, voluntary filer or otherwise), quarterly reports on Form 10-Q (or any successor or comparable form),

(c) promptly from time to time after the occurrence of an event required to be therein reported (and in any event within the time period specified for filing current reports on Form 8-K by the SEC), such other reports on Form 8-K (or any successor or comparable form), and

(d) any other information, documents and other reports which the Company would be required to file with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act;

-48-

provided, however, that the Company shall not be so obligated to file such reports with the SEC if the SEC does not permit such filing, in which event the Company shall put such information on its website, in addition to providing such information to the Trustee and the Holders, in each case within 15 days after the time the Company would be required to file such information with the SEC if it were subject to Section 13 or 15(d) of the Exchange Act. For avoidance of doubt, the obligations of the Company under this Section 4.02 shall commence with respect to the Company’s first fiscal quarter that ends after the Issue Date.

In addition, to the extent not satisfied by the foregoing, the Company shall, for so long as any Securities are outstanding, furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Notwithstanding the foregoing, the Company will be deemed to have furnished such reports referred to above to the Trustee and the Holders if it has filed such reports with the SEC via the EDGAR filing system (or any successor thereto) and such reports are publicly available.

Notwithstanding the foregoing, the requirement to provide the information and reports referred to in clauses (a) and (b) above shall be deemed satisfied prior to the commencement of the Registered Exchange Offer or the effectiveness of a Shelf Registration Statement relating to the registration of the Securities under the Securities Act by the filing (within the time periods specified for such filings in the registration rights agreement) with the SEC of a registration statement, and any amendments thereto, with such financial information that satisfies Regulation S-X under the Securities Act.

In the event that:

(i) the rules and regulations of the SEC permit the Company and any direct or indirect parent company of the Company to report at such parent entity’s level on a consolidated basis and such parent entity of the Company is not engaged in any business in any material respect other than incidental to its ownership, directly or indirectly, of the capital stock of the Company, or

(ii) any direct or indirect parent of the Company becomes a Guarantor of the Securities,

such consolidated reporting at such parent entity’s level in a manner consistent with that described in this Section 4.02 for the Company will satisfy this Section 4.02; provided that such financial information is accompanied by consolidating information that explains in reasonable detail the differences between the information relating to such direct or indirect parent and any of its Subsidiaries other than the Company and its Subsidiaries, on the one hand, and the information relating to the Company and its Subsidiaries on a stand alone basis, on the other hand.

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice

-49-

of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively (subject to Article 7) on Officers’ Certificates).

SECTION 4.03. Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.

(a) (i) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness) or issue any shares of Disqualified Stock; and (ii) the Company shall not permit any of its Restricted Subsidiaries to issue any shares of Preferred Stock; provided, however, that the Company and any Restricted Subsidiary may Incur Indebtedness (including Acquired Indebtedness) or issue shares of Disqualified Stock and any Restricted Subsidiary may issue shares of Preferred Stock, in each case if the Fixed Charge Coverage Ratio of the Company for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is Incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.00 to 1.00 determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been Incurred, or the Disqualified Stock or Preferred Stock had been issued, as the case may be, and the application of proceeds therefrom had occurred at the beginning of such four-quarter period; provided, further, that Restricted Subsidiaries of the Company that are not Guarantors may not Incur Indebtedness or issue any shares of Disqualified Stock or Preferred Stock pursuant to this paragraph if, after giving pro forma effect to such Incurrence or issuance (including a pro forma application of the net proceeds therefrom), more than an aggregate of $10 million of Indebtedness, Disqualified Stock and Preferred Stock of Restricted Subsidiaries that are not Guarantors would be outstanding pursuant to this paragraph.

(b) The limitations set forth in Section 4.03(a) shall not apply to (collectively, “Permitted Debt”):

(i) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness under one or more Credit Facilities and the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder) up to an aggregate principal amount at any one time outstanding not to exceed the greater of (x) $200 million and (y) the amount of the Borrowing Base, as of the date of such Incurrence;

(ii) the Incurrence by the Company and the Guarantors of Indebtedness represented by the Original Securities and the Guarantees, as applicable (and any Exchange Securities and guarantees thereof);

(iv) Indebtedness (including Capitalized Lease Obligations) Incurred by the Company or any of its Restricted Subsidiaries to finance the purchase, lease, design, construction, installation, repair, replacement or improvement of property (real or personal) or equipment (whether through the direct purchase of assets or the Capital Stock of any Person owning such assets (but no other material assets)) and related financing costs in an aggregate principal amount which, when aggregated with the principal amount of all other Indebtedness then outstanding that was Incurred pursuant to this clause (iv), does not exceed $20 million at any one time outstanding;

(v) Indebtedness Incurred by the Company or any of its Restricted Subsidiaries constituting reimbursement obligations with respect to letters of credit and bank guarantees issued in the ordinary course of business, including, without limitation, letters of credit in respect of workers’ compensation claims, health, disability or other employee benefits (whether current or former) or property, casualty or liability insurance or self-insurance, or other Indebtedness with respect to reimbursement-type obligations regarding workers’ compensation claims; provided, however, that upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing;

(vii) Indebtedness of the Company to a Restricted Subsidiary; provided that any subsequent issuance or transfer of any Capital Stock or any other event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an Incurrence of such Indebtedness;

(viii) shares of Preferred Stock of a Restricted Subsidiary issued to the Company or another Restricted Subsidiary; provided that any subsequent issuance or transfer of any Capital Stock or any other event that results in any Restricted Subsidiary that holds such shares of Preferred Stock of another Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to the Company or another Restricted Subsidiary) shall be deemed, in each case, to be an issuance of shares of Preferred Stock;

(ix) Indebtedness of a Restricted Subsidiary to the Company or another Restricted Subsidiary; provided that if a Guarantor incurs such Indebtedness to a Restricted Subsidiary that is not a Guarantor, such Indebtedness must be subordinated in right of payment to the Guarantee of such Guarantor; provided, further, that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary lending such Indebtedness ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to the Company or another

(xiii) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness or Disqualified Stock or the issuance by any Restricted Subsidiary of any Preferred Stock which serves to refinance, refund, renew, replace, defease, discharge or otherwise retire for value, in whole or in part, any Indebtedness, Disqualified Stock or Preferred Stock Incurred as permitted under Section 4.03(a) and clauses (ii), (iii), (iv) and (xiii) of this Section 4.03(b) or any Indebtedness, Disqualified Stock or Preferred Stock Incurred to so refinance, refund, renew, replace, defease, discharge or otherwise retire for value, such Indebtedness, Disqualified Stock or Preferred Stock, including any Indebtedness, Disqualified Stock or Preferred Stock Incurred to pay premiums, fees and expenses in connection therewith (subject to the following proviso, “Refinancing Indebtedness”) prior to its respective maturity; provided, however, that:

-52-

(1) such Refinancing Indebtedness has a Weighted Average Life to Maturity at the time such Refinancing Indebtedness is Incurred which is not less than the remaining Weighted Average Life to Maturity of the Indebtedness being refunded, refinanced, renewed, replaced, defeased, discharged or retired;

(2) such Refinancing Indebtedness has a Stated Maturity which is no earlier than the Stated Maturity of the Indebtedness being refinanced, refunded, renewed, replaced, defeased, discharged or retired;

(3) to the extent such Refinancing Indebtedness refinances, refunds, renews, replaces, defeases, discharges, or retires (x) Indebtedness junior to the Securities or the Guarantee of such Restricted Subsidiary, as applicable, such Refinancing Indebtedness is junior to the Securities or the Guarantee of such Restricted Subsidiary, as applicable or (y) Disqualified Stock or Preferred Stock, such Refinancing Indebtedness is Disqualified Stock or Preferred Stock;

(4) the aggregate principal amount (or, in the case of Disqualified Stock, the amount thereof as determined in accordance with the definition of Disqualified Stock) of such Refinancing Indebtedness is equal to or less than the aggregate principal amount (or in the case of Disqualified Stock, the amount thereof as determined in accordance with the definition of Disqualified Stock) then outstanding of the Indebtedness or Disqualified Stock being refinanced, refunded, renewed, replaced, defeased, discharged or retired plus all accrued interest on the Indebtedness or accrued dividends on the Disqualified Stock, as the case may be, being refinanced, refunded, renewed, replaced, defeased, discharged or retired and all premiums, expenses and fees incurred in connection with such refinancing; and

(5) such Refinancing Indebtedness shall not include (x) Indebtedness of a Restricted Subsidiary that is not a Guarantor that refinances Indebtedness of the Company or a Guarantor, or (y) Indebtedness of the Company or a Restricted Subsidiary that refinances Indebtedness of an Unrestricted Subsidiary;

(xiv) Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against insufficient funds in the ordinary course of business; provided that such Indebtedness is extinguished within five Business Days of its Incurrence;

(xv) Indebtedness of the Company or any Restricted Subsidiary supported by a letter of credit or bank guarantee issued pursuant to a Credit Facility, in a principal amount not in excess of the stated amount of such letter of credit or bank guarantee;

(xvi) Indebtedness of the Company or any Restricted Subsidiary consisting of (x) the financing of insurance premiums or (y) take-or-pay obligations contained in supply arrangements, in each case, in the ordinary course of business; and

-53-

(xvii) Indebtedness or Disqualified Stock of the Company or any Restricted Subsidiary and Preferred Stock of any Restricted Subsidiary in an aggregate principal amount which, when aggregated with the principal amount or liquidation preference of all other Indebtedness, Disqualified Stock and Preferred Stock then outstanding and Incurred pursuant to this clause (xvii) does not exceed the greater of (x) $25.0 million and (y) 3.5% of Consolidated Net Tangible Assets at the time of Incurrence, at any one time outstanding (which Indebtedness may be incurred, in whole or in part, under a Credit Facility).

(c) Notwithstanding the foregoing, neither the Company nor any Guarantor may Incur any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are used, directly or indirectly, to repay, prepay, redeem, defease, retire, refund or refinance any Subordinated Indebtedness unless such Indebtedness shall be subordinated to the Securities or such Guarantor’s Guarantee, as applicable, to at least the same extent as such Subordinated Indebtedness. For purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock meets the criteria of more than one of the categories of Permitted Debt or is entitled to be Incurred pursuant to Section 4.03(a), the Company shall be permitted to divide or classify (or later divide, classify or reclassify), in whole or in part in its sole discretion, such item of Indebtedness, Disqualified Stock or Preferred Stock in any manner that complies with this Section 4.03 and such item of Indebtedness, Disqualified Stock or Preferred Stock shall be treated as having been Incurred pursuant to only one of the clauses in Section 4.03(b) or pursuant to Section 4.03(a); provided that all Indebtedness under the Credit Agreement outstanding on the Issue Date shall be deemed to have been Incurred pursuant to clause (i) of Section 4.03(b) and the Company shall not be permitted to reclassify all or any portion of such Indebtedness. 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, the payment of dividends on Preferred Stock in the form of additional shares of Preferred Stock of the same class, 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 shall not be deemed to be an Incurrence of Indebtedness for purposes of this Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which are 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.

(d) For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term debt, or first committed or first Incurred (whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such

-54-

refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced.

SECTION 4.04. Limitation on Restricted Payments.

(a) The Company 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 the Company’s or any of its Restricted Subsidiaries’ Equity Interests, including any payment made in connection with any merger or consolidation involving the Company (other than (A) dividends or distributions by the Company payable solely in Equity Interests (other than Disqualified Stock) of the Company; 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 other than a Wholly Owned Restricted Subsidiary, the Company 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 the Company or any Parent Company;

(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 (other than the payment, redemption, repurchase, defeasance, acquisition or retirement of Subordinated Indebtedness in anticipation of satisfying a sinking fund 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; 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 or Event of 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, the Company 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 the Company and its Restricted Subsidiaries after the Issue Date (including Restricted Payments permitted by clause (i) of Section 4.04(b), but excluding all other Restricted Payments permitted by Section 4.04(b)), is less than the sum of, without duplication,

-55-

(A) 50% of the Consolidated Net Income of the Company for the period (taken as one accounting period) from October 1, 2010 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, in the case such Consolidated Net Income for such period is a deficit, minus 100% of such deficit), plus

(B) 100% of the aggregate net proceeds, including cash and the Fair Market Value (as determined in accordance with the next succeeding sentence) of property other than cash, received by the Company after the Issue Date from the issue or sale of Equity Interests of the Company (excluding (without duplication) Refunding Capital Stock, Designated Preferred Stock, Excluded Contributions and Disqualified Stock), including Equity Interests issued upon conversion of Indebtedness or upon exercise of warrants or options (other than an issuance or sale to a Subsidiary of the Company or an employee stock ownership plan or trust established by the Company or any of its Subsidiaries), plus

(C) without duplication of any amount included in clause (B) above, 100% of the aggregate amount of contributions to the capital of the Company received in cash and the Fair Market Value (as determined in accordance with the next succeeding sentence) of all property other than cash received by the Company as a contribution to its capital after the Issue Date (other than Excluded Contributions, Refunding Capital Stock, Designated Preferred Stock and Disqualified Stock), plus

(D) the principal amount of any Indebtedness, or the liquidation preference or maximum fixed repurchase price, as the case may be, of any Disqualified Stock, of the Company or any Restricted Subsidiary thereof issued after the Issue Date (other than Indebtedness or Disqualified Stock issued to a Restricted Subsidiary) which has been converted into or exchanged for Equity Interests in the Company or such Restricted Subsidiary (other than Disqualified Stock), plus

(E) the amount equal to the net reduction in Investments (other than Permitted Investments) made by the Company or any of its Restricted Subsidiaries in any Person resulting from, and without duplication, (I) repurchases or redemptions of such Investments by such Person, proceeds realized upon the sale of such Investment to an unaffiliated purchaser and repayments of loans or advances or other transfers of assets by such Person to the Company or any Restricted Subsidiary (including by way of dividend or distribution) or (II) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries or the merger or consolidation of an Unrestricted Subsidiary with and into the Company or any Restricted Subsidiary (valued in each case as provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any of its Restricted Subsidiaries in such

-56-

Unrestricted Subsidiary, which amount was included in the calculation of Restricted Payments.

The Fair Market Value of property other than cash covered by clauses (3)(B), (C), (D) and (E) of this Section 4.04(a) shall be determined in good faith by the Company and in the event of property with a Fair Market Value in excess of $10 million, shall be set forth in a resolution approved by at least a majority of the Board of Directors of the Company.

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

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

(ii) (A) the redemption, repurchase, retirement or other acquisition of any Equity Interests (“Retired Capital Stock”) of the Company, any Parent Company or any Guarantor or any Subordinated Indebtedness of the Company, any Parent Company or any Guarantor in exchange for, or out of the proceeds of the substantially concurrent sale of, Equity Interests of the Company or any Parent Company or contributions to the equity capital of the Company or any Restricted Subsidiary (other than any Disqualified Stock or any Equity Interests sold to a Subsidiary of the Company or to an employee stock ownership plan or any trust established by the Company or any of its Subsidiaries) (collectively, including any such contributions, “Refunding Capital Stock”); and (B) the declaration and payment of accrued dividends on the Retired Capital Stock out of the proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company or to an employee stock ownership plan or any trust established by the Company or any of its Subsidiaries) of Refunding Capital Stock;

(A) the principal amount of such new Indebtedness does not exceed the principal amount of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired for value (plus all accrued and unpaid interest on such Subordinated Indebtedness and the amount of any premiums required to be paid under the terms of the instrument governing the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired plus any fees and expenses incurred in connection therewith);

-57-

(C) such Indebtedness has a final scheduled maturity date equal to or later than the earlier of: (A) the final scheduled maturity date of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired and (B) 91 days following the last maturity date of any notes then outstanding; and

(D) such Indebtedness has a Weighted Average Life to Maturity equal to or greater than the shorter of: (A) the remaining Weighted Average Life to Maturity of the Subordinated Indebtedness being so redeemed, repurchased, defeased, acquired or retired and (B) 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 91 days following the last maturity date of any notes then outstanding were instead due on such date;

(iv) the repurchase, retirement or other acquisition for value of Equity Interests of the Company or any Parent Company held by any future, present or former employee, director or consultant of the Company, any Parent Company or any Subsidiary of the Company, and any dividend payment or other distribution by the Company or a Restricted Subsidiary to any Parent Company the proceeds of which are utilized for the repurchase, retirement or other acquisition for value of Equity Interests such Parent Company held by any future, present or former employee, director or consultant of the Company, any Parent Company or any Subsidiary of the Company, in each case 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 amounts paid under this clause (iv) do not exceed $5 million in any calendar year (with unused amounts in any calendar year being permitted to be carried over for the next calendar year); 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 the Company or any of its Restricted Subsidiaries from the sale of Equity Interests (other than Disqualified Stock) of the Company and, to the extent contributed to the capital of the Company, the Equity Interests of any Parent Company, in each case to members of management, directors or consultants of the Company, any Parent Company or any Restricted Subsidiary after the Issue Date (provided that the amount of such cash proceeds utilized for any such repurchase, retirement, other acquisition or dividend shall not increase the amount available for Restricted Payments under Section 4.04(a)(3)); plus

(B) the cash proceeds of key man life insurance policies received by the Company and its Restricted Subsidiaries after the Issue Date

-58-

(provided that the Company may elect to apply all or any portion of the aggregate increase contemplated by clauses (A) and (B) above in any calendar year);

-59-

such Change of Control or Asset Sale, as the case may be, and has repurchased all Securities validly tendered and not withdrawn in connection with such Change of Control Offer or Asset Sale Offer, as the case may be;

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

(c) As of the Issue Date, all of the Company’s Subsidiaries shall be Restricted Subsidiaries. The Company shall 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 the Company and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall be deemed to be Restricted Payments or Permitted Investments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation shall 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. The Company shall not, and shall not permit any of its 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 Restricted Subsidiary to:

(3) applicable law or any applicable rule, regulation, order, approval, license, permit or similar restriction;

-60-

(4) any agreement or other instrument of a Person acquired by the Company or any Restricted Subsidiary which was in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired;

(11) other Indebtedness, Disqualified Stock or Preferred Stock of any Restricted Subsidiary that is Incurred subsequent to the Issue Date pursuant to Section 4.03; provided that such encumbrances and restrictions contained in any agreement or instrument will not materially affect the Company’s ability to make anticipated principal or interest payment on the Securities (as determined by the Company in good faith);

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 ordinary shares 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 the Company or a Restricted Subsidiary to other Indebtedness Incurred by the Company or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances.

SECTION 4.06. Asset Sales.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to consummate an Asset Sale, unless:

(1) the Company or any of its Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value (as determined in good faith by the Company) of the assets sold or otherwise disposed of;

(2) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents; provided that the amount of:

(i) any liabilities (as shown on the Company’s or any Restricted Subsidiary’s most recent balance sheet or in the notes thereto) of the Company or any Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Securities) that are assumed by the transferee of any such assets,

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

-62-

(iii) accounts receivable of a business retained by the Company or any of its Restricted Subsidiaries, as the case may be, following the sale of such business, provided that such accounts receivable (i) are not past due more than 90 days and (ii) do not have a payment date greater than 120 days from the date of the invoices creating such accounts receivable; and

(iv) any Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iv) that is at that time outstanding, not to exceed the greater of (x) $15.0 million and (y) 2.5% of Consolidated Net Tangible Assets 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 each be deemed to be Cash Equivalents for the purposes of this Section 4.06(a).

(3) if such Asset Sale involves the disposition of Collateral, the Company or such Restricted Subsidiary has complied with the provisions of this Indenture and the Security Documents; and

(4) if such Asset Sale involves the disposition of Notes Priority Collateral or, after the Discharge of ABL Obligations, the disposition of ABL Priority Collateral, the Net Cash Proceeds thereof shall be delivered to the Collateral Agent for deposit into the Collateral Account, and, if any property other than cash or Cash Equivalents is included in such Net Cash Proceeds, such property shall be made subject to the Note Liens.

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

(i) to the extent such Net Cash Proceeds constitute proceeds from the sale of ABL Priority Collateral, to repay Indebtedness under the Credit Agreement secured by such ABL Priority Collateral;

(ii) to the extent such Net Cash Proceeds constitute proceeds from the sale of Notes Priority Collateral, to permanently repay, equally and ratably, the Securities and any Permitted Additional Pari Passu Obligations;

(iii) to permanently reduce Obligations under other Secured Indebtedness (provided that if the Company or any Guarantor shall so reduce such Obligations, the Company shall equally and ratably reduce Obligations under the Securities and any Permitted Additional Pari Passu Obligations if the Securities and Permitted Additional Pari Passu Obligations are then prepayable or, if the Securities may not then be prepaid, by

-63-

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, plus accrued and unpaid interest, if any, the pro rata principal amount of Securities that would otherwise be prepaid) or Indebtedness of a Restricted Subsidiary that is not a Guarantor, in each case other than Indebtedness owed to the Company or an Affiliate of the Company;

(iv) to make an investment in any one or more businesses, properties or assets (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 the Company), or to make capital expenditures, in each case used or useful in a Similar Business; and/or

(v) to make an Investment in any one or more businesses, properties or assets (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 the Company), that replace the properties and assets that are the subject of such Asset Sale or Casualty or Condemnation Event; provided that with respect to the replacement or restoration of any property, equipment or assets of the Company that is the subject of a Casualty or Condemnation Event, if the Company or the applicable Guarantor commences replacement or restoration of such property, equipment or assets of the Company within 365 days after receipt of the Net Cash Proceeds from such Casualty or Condemnation Event, the 365 day period shall be extended for so long as the Company or the applicable Guarantor is diligently pursuing such replacement or restoration, subject to any force majeure event; provided, however, that if such Net Cash Proceeds are received in respect of Notes Priority Collateral, such assets constitute Notes Priority Collateral.

In the case of clauses (iv) and (v) above, a binding commitment shall be treated as a permitted application of the Net Cash Proceeds from the date of such commitment, provided that, in the event such binding commitment is later canceled or terminated for any reason before such Net Cash Proceeds are so applied, the Company or such Restricted Subsidiary enters into another binding commitment within 180 days of such cancellation or termination of the prior binding commitment.

Pending the final application of any such Net Cash Proceeds, the Company or the applicable Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise invest such Net Cash Proceeds in Cash Equivalents or Investment Grade Securities. Any Net Cash Proceeds from any Asset Sale or Casualty or Condemnation Event that are not applied as provided and within the time period set forth in this Section 4.06(b) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10 million, the Company shall make an offer (an “Asset Sale Offer”) to all Holders of Securities and (x) in the case of Net Cash Proceeds from Notes Priority Collateral, to the holders of any other Permitted Additional Pari Passu Obligations containing provisions similar to those set forth in this Indenture with respect to Asset Sales or Casualty or Condemnation Event or (y) in the case of any other Net Cash Proceeds, to all holders of other Pari Passu Indebtedness

-64-

containing provisions similar to those set forth in this Indenture with respect to Assets Sales or Casualty or Condemnation Event, to purchase the maximum principal amount of such Securities and Permitted Additional Pari Passu Obligations or Pari Passu Indebtedness, as appropriate, 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 such lesser price, if any, as may be provided by the terms of such other Indebtedness), plus accrued and unpaid interest and Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Section 4.06 and, in the case of Securities, is an integral multiple of $2,000. The Company shall commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceed $10 million by mailing the notice required pursuant to the terms of Section 4.06(f), with a copy to the Trustee and the Registrar. To the extent that the aggregate amount of Securities and such other Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes. If the aggregate principal amount of Securities and Permitted Additional Pari Passu Obligations or Pari Passu Indebtedness, as appropriate, surrendered by holders thereof exceeds the amount of Excess Proceeds, the Registrar shall select the Securities and such other Indebtedness 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 Company shall 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 Securities 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 Company shall 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 and the Registrar as provided above, the Company shall deliver to the Trustee and the Registrar an Officers’ Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Cash Proceeds from the Asset Sales or Casualty or Condemnation Event 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). Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer Period”), the Company shall deliver to the Registrar for cancellation the Securities or portions thereof that have been properly tendered to and are to be accepted by the Company. The Paying Agent 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 Company to the Paying Agent is greater than the purchase price of the Securities tendered, the Paying Agent shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with Section 4.06.

(e) Holders electing to have a Security purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified

-65-

in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Registrar or the Company receives not later than two Business Days prior to the purchase date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered by the Holder for purchase and a statement that such Holder is withdrawing his election to have such Security purchased. If at the end of the Offer Period more Securities are tendered pursuant to an Asset Sale Offer than the Company is required to purchase, selection of such Securities for purchase shall be made by the Registrar in compliance with the requirements of the principal national securities exchange, if any, on which such Securities are listed, or if such Securities are not listed by lot or such other method as the Registrar shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that, to the extent practicable, the Registrar shall not select Securities for purchase which would result in a Holder with a principal amount of Securities less than the minimum denomination.

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

(g) A new Security in principal amount equal to the unpurchased portion of any Security purchased in part shall be issued in the name of the Holder thereof upon cancellation of the original Security. On and after the purchase date, unless the Company defaults in payment of the purchase price, interest shall cease to accrue on Securities or portions thereof purchased.

SECTION 4.07. Transactions with Affiliates.

(a) The Company shall not, and shall not permit any of its 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 the Company (each of the foregoing, an “Affiliate Transaction”), unless:

(i) such Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Company’s Board of Directors, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view;

(ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15 million, the Company delivers to the Trustee a resolution adopted in good faith by the majority of the Board of

(v) any agreement as in effect as of the Issue Date or any amendment thereto (so long as any such agreement together with all amendments thereto, taken as a whole, is not more disadvantageous to the Holders of the Securities in any material respect than the original agreement as in effect on the Issue Date) or any transaction contemplated thereby;

(vi) (A) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, or lessors or lessees of property, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture, which are fair to the Company and its Restricted Subsidiaries in the reasonable determination of the Board of Directors or any executive officer of the Company, and are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party or (B) transactions with joint ventures or Unrestricted Subsidiaries entered into in the ordinary course of business;

(vii) any contribution to the capital of the Company or any issuance of Capital Stock of the Company;

-67-

SECTION 4.12. Liens.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, Incur or suffer to exist any Lien (other than Permitted Liens) on any asset or property of the Company or such Restricted Subsidiary that secures any Indebtedness of the Company or such Restricted Subsidiary or any related guarantees, except that the Company and the Restricted Subsidiaries may Incur or suffer to exist Liens on assets not constituting Collateral, so long as the Company or such Restricted Subsidiary effectively provides that the Securities or the applicable Guarantee, as the case may be, shall be equally and ratably secured with (or on a senior basis to, in the case such Lien secures any Subordinated Indebtedness) the Indebtedness or related guarantees secured by such Lien.

(b) Section 4.12(a) shall not require the Company or any Restricted Subsidiary to secure the Securities if the relevant Lien consists of a Permitted Lien.

(b) The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations.

(b) The Company and Guarantors will

(i) cause any property and casualty insurance policies with respect to the Mortgaged Property to be endorsed or otherwise amended to include a lender’s loss payable endorsement and cause all property policies and casualty insurance policies to name the Collateral Agent as loss payee; and such other provisions as may be customary with companies in the same or similar businesses to protect their interests; deliver original or certified copies of all such policies or a certificate of an insurance broker to the Collateral Agent; cause each such policy to provide that it shall not be canceled or not renewed upon less than 30 days’ prior written notice thereof by the insurer to the Collateral Agent; deliver to the Collateral Agent, prior to the cancellation or nonrenewal of any such policy of insurance, a copy of a renewal or replacement policy (or other evidence of renewal of a policy previously delivered to the Collateral Agent), or insurance certificate with respect thereto, together with evidence of payment of the premium therefor;

(ii) if the area in which any Building (as defined in Section 339.2 of the Federal Deposit Insurance Corporation Regulations and being codified to 12 CFR §339.2) is located on any Mortgaged Property is designated a “special flood hazard area” in any Flood Insurance Rate Map published by the Federal Emergency Management Agency (or any successor agency), as determined by a Federal Emergency Management Agency Standard Flood Hazard Determination, the Company or its applicable Subsidiary shall maintain flood insurance, as required in order to comply with the Flood Insurance Laws, with respect to such portion of the Mortgaged Property and naming the Collateral Agent for its benefit and the benefit of the Trustee and the Secured Creditors as mortgagee/loss payee;

If, however, the insurance policies do not provide waiver of subrogation rights against such parties, as required above, then each of Company, and the Guarantors hereby agree, to the extent permitted by law, to waive, its right of recovery, if any, against the Trustee, the Collateral Agent and the Secured Parties and their agents and employees; and

DEFAULTS AND REMEDIES

(b) the Company defaults in the payment of principal or premium, if any, of any Security when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise,

(d) the Company or any of its Restricted Subsidiaries fails to comply with any of its obligations under the covenants set forth in Sections 4.08 (other than a failure to purchase Securities when required under Section 4.08) and such failure continues for 30 days after receipt of a related Notice of Default as specified below,

(e) the Company or any of its Restricted Subsidiaries fails to comply with any of its covenants or agreements in the Securities or this Indenture (other than those referred to in (a), (b), (c), or (d) above) and such failure continues for 60 days after receipt of a related Notice of Default as specified below,

(f) the Company or any Significant Subsidiary fails to pay any Indebtedness for money borrowed (other than Indebtedness owing to the Company or a Restricted Subsidiary of the Company) 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 $15 million,

-80-

(g) the Company or any Significant Subsidiary of the Company 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 equivalent action under any foreign laws relating to insolvency,

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

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

(ii) appoints a Custodian of the Company or any Significant Subsidiary of the Company or for all or substantially all of its property; or

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

(i) the Company or any Significant Subsidiary fails to pay final and non-appealable judgments aggregating in excess of $15 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 following the entry thereof,

(j) the Guarantee of a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms thereof) or any Guarantor that is a Significant Subsidiary denies or disaffirms its obligations under this Indenture or any Guarantee and such Default continues for 10 days after receipt of a related Notice of Default as specified below, or

(k) unless all of the Collateral has been released from the Note Liens in accordance with the provisions of the Security Documents, the Company or any Guarantor defaults in the performance of the Security Documents which adversely affects in any material respect the enforceability, validity, perfection or priority of the Note Liens on a material portion of the Collateral, the repudiation or disaffirmation by the Company or

-81-

any Guarantor of its material obligations under the Security Documents or the determination in a judicial proceeding that the Security Documents are unenforceable or invalid against the Company or any Guarantor party thereto for any reason with respect to a material portion of the Collateral, which default, repudiation, disaffirmation or determination is not rescinded, stayed, or waived by the Persons having such authority pursuant to the Security Documents or otherwise cured within 60 days after receipt of a related Notice of Default as specified below.

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.

The term “Bankruptcy Law” means Title 11, United States 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.

A Default under clause (c), (d), (e), (i) or (k) above shall not constitute an Event of Default until the Trustee notifies the Company in writing or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company and the Trustee in writing of the Default and the Company does not cure such Default within the time specified in clauses (c), (d), (e), (i) or (k) above 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.” The Company shall deliver to the Trustee, within thirty (30) days after the occurrence thereof, written notice 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 Company is taking or proposes to take with respect thereto.

SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(g) or (h) with respect to the Company) occurs and is continuing, the Trustee by written notice to the Company or the Holders of at least 25% in principal amount of outstanding Securities by written notice to the Company and the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Securities 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(g) or (h) with respect to the Company occurs, the principal of, premium, if any, and interest on all the Securities shall ipso facto become and be 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 the Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

In the event of any Event of Default specified in Section 6.01(f), such Event of Default and all consequences thereof shall be annulled, waived and rescinded, automatically and

-82-

without any action by the Trustee or the Holders of the Securities, if within 20 days after such Event of Default arose the Company delivers an Officers’ Certificate to the Trustee stating that (x) the Indebtedness or guarantee that is the basis 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 Securities 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 Securities or to enforce the performance of any provision of the Securities, this Indenture or the Security Documents.

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

SECTION 6.04. Waiver of Past Defaults. Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences except (a) a Default or Event of Default in the payment of the principal of or interest on a Security or (b) a Default or Event of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When a Default is waived, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05. Control by Majority. Subject to the terms of the Security Documents, the Holders of a majority in principal amount of the Securities then outstanding 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, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. 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.

-83-

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 Securities unless:

(i) the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

(ii) the Holders of at least 25% in principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy;

(iii) such Holder or Holders offer to the Trustee security or indemnity reasonably satisfactory to it against any loss, liability or expense;

(iv) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and

(v) the Holders of a majority in principal amount of the Securities do not give the Trustee a direction inconsistent with the request during 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. Rights of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed or provided for in the Securities, 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 Company or any other obligor on the Securities 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 Securities) 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 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 reasonably necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Company or any Guarantor, 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

-84-

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 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.

SECTION 6.10. Priorities. Subject to the terms of the Security Documents, if the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

FIRST: to the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent for amounts due under Section 7.07;

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

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

The Trustee, upon prior written notice to the Company and the Guarantors, 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 send to each Holder and the Company a notice that states the record date, the payment date and 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 Section 6.11 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 Securities then outstanding.

SECTION 6.12. Waiver of Stay or Extension Laws. Neither the Company nor any 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 Company and each Guarantor (to the extent that it 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 Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

SECTION 7.01. Duties of Trustee.

(a) 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.

(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

(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.

(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 and, from the date on which this Indenture is qualified under the TIA, to the provisions of the TIA.

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.

(c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence.

(e) The Trustee may consult with counsel of its own selection and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document unless requested in writing to do so by the Holders of not less than a majority in principal amount of the Securities at the time outstanding, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation.

(g) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to

-87-

this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses, losses and liabilities which might be incurred by it in compliance with such request or direction.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, Deutsche Bank Trust Company Americas in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

(i) In the event the Company is required to pay Additional Interest, the Company will provide written notice to the Trustee of the Company’s obligation to pay Additional Interest no later than 15 days prior to the next interest payment date, which notice shall set forth the amount of the Additional Interest to be paid by the Company. The Trustee shall not at any time be under any duty or responsibility to any Holders to determine whether the Additional Interest is payable and the amount thereof.

SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, the Trustee must comply with Sections 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, any Guarantee or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company or any Guarantor in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication. The Trustee shall not be charged with knowledge of any Default or Event of Default under Sections 6.01(c), (d), (e), (f), (i), (j) 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 notice thereof in accordance with Section 13.02 from the Company, any Guarantor or any Holder.

SECTION 7.05. Notice of Defaults. If a Default occurs and is continuing and if it is actually known to a Trust Officer, the Trustee shall send to each Holder notice of the Default within the earlier 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. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Security, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of the Holders.

SECTION 7.06. Reports by Trustee to the Holders. From the date on which this Indenture is qualified under the TIA, as promptly as practicable after each June 30 beginning with the June 30 following the date of this Indenture, and in any event within 12 months of the last such report, the Trustee shall send to each Holder a brief report dated as of such June 30 that complies with Section 313(a) of the TIA if and to the extent required thereby. From the date on

-88-

which this Indenture is qualified under the TIA, the Trustee shall also comply with Section 313(b)(2) of the TIA.

A copy of each report at the time of its delivery to the Holders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

SECTION 7.07. Compensation and Indemnity. The Company shall pay to Deutsche Bank Trust Company Americas, in each of its capacities, and through Deutsche Bank Trust Company Americas to Trustee from time to time reasonable compensation for its and Trustee’s services (it being understood all amounts set forth in the fee letter dated September 24, 2010 between the Company and Deutsche Bank Trust Company Americas shall be deemed reasonable). The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee, Paying Agent, Registrar and Authentication Agent upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in the performance of services rendered under this Indenture, any Security Document and any related document to which it is a party, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s, Paying Agent’s, Registrar’s and Authentication Agent’s agents, counsel, accountants and experts. The Company and each Guarantor, jointly and severally shall indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) 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 Guarantee against the Company or a Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by the Company, any Guarantor, any Holder or any other Person). The Trustee shall notify the Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Company shall not relieve the Company or any Guarantor of its indemnity obligations hereunder. The Company shall defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have separate counsel and the Company and the Guarantors, as applicable shall pay the fees and expenses of such counsel; provided, however, that the Company shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Company and the Guarantors, as applicable, and such parties in connection with such defense. The Company 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 Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Securities 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 Securities.

-89-

The Company’s and the 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 after the occurrence of a Default specified in Section 6.01(g) or (h) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

SECTION 7.08. Replacement of Trustee.

(a) The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company may remove the Trustee if:

(i) the Trustee fails to comply with Section 7.10;

(ii) the Trustee is adjudged bankrupt or insolvent;

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

(iv) the Trustee otherwise becomes incapable of acting.

If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture.

(b) If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

(c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.07.

(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 Securities may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

-90-

(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 Security 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.

(f) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

SECTION 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section 310(a) of the TIA. The Trustee shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Section 310(b) of the TIA, subject to its right to apply for a stay of its duty to resign under the penultimate paragraph of Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any series of securities issued under this Indenture and any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met.

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated.

ARTICLE 8

DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.01. Discharge of Liability on Securities; Defeasance. This Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights of registration or transfer or exchange of Securities, as expressly provided for in this Indenture) as to all outstanding Securities when:

(a) (i) all the Securities theretofore authenticated and delivered (other than mutilated, lost, stolen or destroyed Securities which have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Registrar for cancellation or (ii) all of the Securities (a) have become due and payable, (b) will become due and payable at their stated maturity within one year or (c) if redeemable at the option of the Company, are to be

-91-

called for redemption within one year under arrangements satisfactory to the Registrar for the giving of notice of redemption by the Registrar in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Paying Agent funds in cash in U.S. Dollars, U.S. Government Obligations or a combination thereof in an amount sufficient in the written opinion of a investment banking firm, appraisal firm or firm of independent public accountants delivered to the Trustee and Registrar (which delivery shall only be required if U.S. Government Obligations have been so deposited) to pay and discharge the entire Indebtedness on the Securities not theretofore delivered to the Registrar for cancellation, for principal of, premium, if any, and interest on the Securities to the date of deposit together with irrevocable instructions from the Company directing the Paying Agent to apply such funds to the payment thereof at maturity or redemption, as the case may be;

(b) the Company and/or the Guarantors have paid all other sums payable under this Indenture; and

(c) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with.

Subject to Sections 8.01(c) and 8.02, the Company at any time may terminate (i) all of its obligations under the Securities and this Indenture (with respect to such Securities) (“legal defeasance option”) or (ii) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.10, 4.11, 4.12, 4.14 and 4.15 and the operation of Section 5.01 and Sections 6.01(c), 6.01(d), 6.01(e) (with respect to any Default under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.10, 4.11, 4.12, 4.14 and 4.15), 6.01(f), 6.01(g) (with respect to Significant Subsidiaries of the Company only), 6.01(h) (with respect to Significant Subsidiaries of the Company only), 6.01(i), 6.01(j) and 6.01(k) (“covenant defeasance option”). The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. In the event that the Company terminates all of its obligations under the Securities and this Indenture (with respect to such Securities) by exercising its legal defeasance option or its covenant defeasance option, the obligations of each Guarantor under its Guarantee of such Securities shall be terminated simultaneously with the termination of such obligations.

If the Company exercises its legal defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (with respect to Significant Subsidiaries of the Company only), 6.01(h) (with respect to Significant Subsidiaries of the Company only), 6.01(i), 6.01(j) or 6.01(k) or because of the failure of the Company to comply with Section 5.01.

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

-92-

(d) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08, 11.07(e), 11.12 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.05, 8.06 and 11.12 shall survive such satisfaction and discharge.

SECTION 8.02. Conditions to Defeasance.

(a) The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(i) the Company irrevocably deposits in trust with the Paying Agent cash in U.S. Dollars, U.S. Government Obligations or a combination thereof in an amount sufficient, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants, to pay the principal of, and premium (if any) and interest on the applicable Securities when due at maturity or redemption, as the case may be, including interest thereon to maturity or such redemption date;

(ii) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.01(g) or (h) with respect to the Company occurs which is continuing at the end of the period;

(iii) the deposit does not constitute a default under any other material agreement binding on the Company;

(iv) the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;

(v) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (1) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (2) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred;

(vi) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and

-93-

(vii) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge of the Securities to be so defeased and discharged as contemplated by this Article 8 have been complied with.

Notwithstanding the foregoing, the Opinion of Counsel required by the clause (vi) above need not be delivered if all Securities not theretofore delivered to the Registrar for cancellation (x) have become due and payable or (y) will become due and payable at their Stated Maturity within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

(b) Before or after a deposit, the Company may make arrangements satisfactory to the Trustee and Paying Agent for the redemption of such Securities at a future date in accordance with Article 3.

SECTION 8.03. Application of Trust Money. The Paying Agent shall hold in trust money or U.S. Government Obligations (including proceeds thereof) deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations in accordance with this Indenture to the payment of principal of and interest on the Securities so discharged or defeased.

SECTION 8.04. Repayment to Company. Each of the Trustee and each Paying Agent shall promptly turn over to the Company upon request any money or U.S. Government Obligations held by it as provided in this Article 8 which are, in the opinion of a nationally recognized investment banking firm, appraisal firm or firm of independent public accountants, in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article 8.

Subject to any applicable abandoned property law, the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Company for payment as general creditors, and the Paying Agent shall have no further liability with respect to such monies.

SECTION 8.05. Indemnity for U.S. Government Obligations. The Company shall pay and shall indemnify the Paying Agent against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

SECTION 8.06. Reinstatement. If the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Securities so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8;

-94-

provided, however, that, if the Company has made any payment of principal of or interest on, any such Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Paying Agent.

ARTICLE 9

AMENDMENTS AND WAIVERS

SECTION 9.01. Without Consent of the Holders. The Company and the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent may amend this Indenture, the Securities or the Security Documents without notice to or consent of any Holder:

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

(ii) to comply with Article 5;

(xiii) to secure any Permitted Additional Pari Passu Obligations under the Security Documents and to appropriately include the same in the Intercreditor Agreement.

Upon the request of the Company and the Guarantors accompanied by a resolution of the Board of Directors of each of the Company and the Guarantors authorizing the execution of any supplemental indenture entered into to effect any such amendment, supplement or waiver, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent shall join with the Company and the Guarantors in the execution of such supplemental indenture. After an amendment under this Section 9.01 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01.

SECTION 9.02. With Consent of the Holders.

(a) The Company and the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent may amend this Indenture or the Securities with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for Securities) and any past default or compliance with any provision of this Indenture, the Securities, the Guarantees or the Security Documents may be waived with the consent of the Holders of a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange for, the Securities). However, without the consent of each Holder of an outstanding Security affected, an amendment may not:

(i) reduce the amount of Securities whose Holders must consent to an amendment;

(ii) reduce the rate of or extend the time for payment of interest on any Security;

(iii) reduce the principal of or change the Stated Maturity of any Security;

(iv) reduce the premium payable upon the redemption of any Security or change the time at which any Security may be redeemed in accordance with Article 3;

(v) make any Security payable in money other than that stated in such Security;

(vi) impair the right of any Holder to receive payment of, principal of, premium, if any, and interest on such Holder’s Securities on or after the date due or to institute

-96-

suit for the enforcement of any payment on or with respect to such Holder’s Securities;

(vii) make any change in Section 6.04 or 6.07 or the second sentence of this Section 9.02(a);

(viii) expressly subordinate the Securities or any Guarantee or otherwise modify the ranking thereof to any other Indebtedness of the Company or any Guarantor;

(ix) modify the Guarantees in any manner adverse to the Holders; or

(x) make any change in the provisions in the Intercreditor Agreement or this Indenture dealing with the application of proceeds of Collateral that would adversely affect the Holder of the Securities.

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

(b) Notwithstanding the requirements of Sections 9.02(a) and (b), any amendment to, or waiver of, the provisions of this Indenture, any Security Document or any other indenture governing Permitted Additional Pari Passu Obligations that has the effect of releasing all or substantially all of the Collateral from the Liens securing the Securities or otherwise modifies the Intercreditor Agreement or other Security Documents in any manner adverse in any material respect to the Holders of the Securities will require the consent of the Holders of at least 66²/3% in aggregate principal amount of the Securities and any Permitted Additional Pari Passu Obligations then outstanding.

(c) After an amendment under this Section 9.02 becomes effective, the Company shall mail to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

SECTION 9.03. Compliance with Trust Indenture Act. From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement to this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents and Waivers.

(a) A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers’ Certificate from the Company certifying that the requisite principal amount of Securities have consented.

-97-

After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt by the Company or the Trustee of consents by the Holders of the requisite principal amount of securities, (ii) satisfaction of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or supplemental indenture) by the Company and the Trustee.

(b) The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 9.05. Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Company may require the Holder of the Security to deliver it to the Registrar. The Registrar may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Registrar so determines, the Company in exchange for the Security shall issue and the Authentication Agent shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment, supplement or waiver.

SECTION 9.06. Trustee to Sign Amendments. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it.

GUARANTEES

SECTION 10.01. Guarantees.

(a) Each Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees, as a primary obligor and not merely as a surety, to each Holder and to the Trustee and its successors and assigns (i) the full and punctual payment when due, whether at Stated Maturity, by acceleration, by redemption or otherwise, of all obligations of the Company under this Indenture (including obligations to the Trustee, Collateral Agent, Paying Agent, Registrar and Authentication Agent) and the Securities, whether for payment of principal of, premium, if any, or interest on in respect of the Securities and all other monetary obligations of the Company under this Indenture and the Securities and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether for fees, expenses, indemnification or otherwise under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b) Each Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities or any other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (iv) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any Guarantor; (v) the failure of any Holder or Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of such Guarantor, except as provided in Section 10.02(b).

(c) Each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives any right to which it may be entitled to have the assets of the Company first be used and depleted as payment of the Company’s or such Guarantor’s obligations hereunder prior to any amounts being claimed

-99-

from or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to which it may be entitled to require that the Company be sued prior to an action being initiated against such Guarantor.

(d) Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

(e) Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

(f) Except as set forth in Sections 8.01 and 10.02, each Guarantor agrees that its Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Except as set forth in Sections 8.01 and 10.02, each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

(g) In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Company to the Holders and the Trustee in respect of the Guaranteed Obligations.

(h) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it,

-100-

on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of any Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 10.01.

(i) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01.

(j) Upon request of the Trustee, each Guarantor 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.

(k) Any Guarantee given by any direct or indirect parent of the Company may be released and discharged from all obligations under this Article 10 at any time upon written notice to the Trustee from such direct or indirect parent of the Company.

SECTION 10.02. Limitation on Liability.

(a) Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture or the Guarantee, as each relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

(b) A Guarantee as to any Guarantor shall automatically terminate and be of no further force or effect and such Guarantor shall be deemed to be released and discharged from all obligations under this Article 10 upon:

(i) the sale, disposition or other transfer (including through merger or consolidation) of all of the Capital Stock of such Guarantor, all or substantially all the assets of such Guarantor or a portion of the Capital Stock of such Guarantor if as a result thereof such Guarantor is no longer a Restricted Subsidiary, in each case if such sale, disposition or other transfer is made in compliance with this Indenture;

(ii) the Company designating such Guarantor to be an Unrestricted Subsidiary in accordance with the provisions set forth in Section 4.04 and the definition of “Unrestricted Subsidiary”;

(iii) in the case of any Restricted Subsidiary which after the Issue Date is required to guarantee the notes pursuant to Section 4.11, the release or discharge of the guarantee by such Restricted Subsidiary of the Indebtedness of the Company or its

-101-

Domestic Subsidiary which resulted in the obligation to guarantee the Securities or the repayment of the Indebtedness of the Company or its Domestic Subsidiary which resulted in the obligation to guarantee the Securities;

(iv) the Company’s exercise of its legal defeasance option or covenant defeasance option as described under Section 8.01 or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture; or

(v) upon the liquidation or dissolution of such Guarantor, provided no Default or Event of Default has occurred or is continuing.

(c) A Guarantee also shall be automatically released upon the applicable Subsidiary ceasing to be a Subsidiary as a result of any foreclosure of any pledge or security interest securing Credit Agreement or other exercise of remedies in respect thereof.

SECTION 10.03. Successors and Assigns. This Article 10 shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.05. Modification. No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.06. Execution of Supplemental Indenture for Future Guarantors. Each Subsidiary and other Person which is required to become a Guarantor pursuant to Section 4.11 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit D hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article 10 and shall guarantee the Guaranteed Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary or other Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or

-102-

transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

SECTION 10.07. Non-Impairment. The failure to endorse a Guarantee on any Security shall not affect or impair the validity thereof.

SECTION 11.07. Collateral Agent.

(a) The Trustee and each of the Holders by acceptance of the Securities hereby acknowledge the Company’s appointment of the Collateral Agent as the Trustee’s collateral agent under this Indenture and the Security Documents and the Trustee and each of the Holders by acceptance of the Securities hereby irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture and the Security Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Security Documents, together with such powers as are reasonably incidental thereto. The Collateral Agent agrees to act as such on the express conditions contained in this Section 11.07. The provisions of this Section 11.07 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor the Company or any of the Guarantors shall have any rights as a third party beneficiary of any of the provisions contained herein other than as expressly provided in Section 11.03. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Security Documents, the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein or in the Security Documents, nor shall the Collateral Agent have or be deemed to have any fiduciary relationship with the Trustee, any Holder or the Company or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Security Documents or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent shall not be construed to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. Except as expressly otherwise provided in this Indenture and the Security Documents, the Collateral Agent shall have and may use its sole discretion with respect to exercising or refraining from exercising any discretionary rights or taking or refraining from taking any actions which the Collateral Agent is expressly entitled to take or assert under this Indenture and the Security Documents, including the exercise of remedies pursuant to Article Six, and any action so taken or not taken shall be deemed consented to by the Trustee and the Holders.

(b) The Collateral Agent may execute any of its duties under this Indenture and the Security Documents by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agent, employee or attorney-in-fact that it selects as long as such selection was made without negligence or willful misconduct.

(c) None of the Collateral Agent or any of its agents or employees shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except for its own negligence or willful misconduct) or under or in connection with any Security Document or the transactions contemplated thereby (except for its own negligence or willful misconduct), or (ii) be responsible in any manner to the Trustee or any Holder for any recital, statement, representation, warranty, covenant or

-107-

agreement made by the Company or any Guarantor, contained in this Indenture or any indenture, or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture or any other indenture, the Security Documents, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture or any other indenture or the Security Documents, or for any failure of the Company or any Guarantor or any other party to this Indenture or the Security Documents to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its agents or employees shall be under any obligation to the Trustee or any Holder to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture or any other indenture or the Security Documents or to inspect the properties, books or records of the Company or any Guarantor.

(d) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee or the Company referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article Six (subject to this Section 11.07); provided, however, that unless and until the Collateral Agent has received any such request, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable.

(e) A resignation or removal of the Collateral Agent and appointment of a successor Collateral Agent shall become effective only upon the successor Collateral Agent’s acceptance of appointment as provided in this Section 11.07(e). The Collateral Agent may resign in writing at any time by so notifying the Company, the Trustee and each trustee, agent or representative of holders of Permitted Additional Pari Passu Obligations at least 30 days prior to the proposed date of resignation. The Company may remove the Collateral Agent if: (i) the Collateral Agent (x) fails to meet the requirements for being a Trustee under Section 7.10 (prior to the discharge or defeasance of this Indenture) and (y) following the discharge or defeasance of this Indenture, fails to meet the requirements for being the trustee, agent or representative of holders of any extant Permitted Additional Pari Passu Obligations; (ii) the Collateral Agent is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Collateral Agent under any Bankruptcy Law; (iii) a custodian or public officer takes charge of the Collateral Agent or its property; or (iv) the Collateral Agent becomes incapable of acting. If the Collateral Agent resigns or is removed or if a vacancy exists in the office of Collateral Agent for any reason, the Company shall promptly appoint a successor Collateral Agent which complies with the eligibility requirements contained in this Indenture and each indenture, credit agreement or other agreements which any Permitted Additional Pari Passu Obligations (other than Additional Securities) are incurred. If a successor Collateral Agent does not take office within 10 days after the retiring Collateral Agent resigns or is removed, the retiring Collateral Agent, the Company or the holders of at least 10% in principal amount of the then outstanding principal amount of (x) the Securities (other than any Additional Securities except to the extent constituting Permitted Additional Pari Passu Obligations) and (y) Permitted Additional Pari Passu Obligations (to the extent the trustee, agent or representative of holders of such Permitted Additional Pari Passu

-108-

Obligations executed a joinder to the Security Agreement) may petition any court of competent jurisdiction for the appointment of a successor Collateral Agent. A successor Collateral Agent shall deliver a written acceptance of its appointment to the retiring Collateral Agent and to the Company. Thereupon, the resignation or removal of the retiring Collateral Agent shall become effective, and the successor Collateral Agent shall have all the rights, powers and the duties of the Collateral Agent under this Indenture and the Security Documents. The successor Collateral Agent shall mail a notice of its succession to the Trustee and each trustee, agent or representative of holders of Permitted Additional Pari Passu Obligations. The retiring Collateral Agent shall promptly transfer all property held by it as Collateral Agent to the successor Collateral Agent, provided that all sums owing to the Collateral Agent hereunder have been paid. Notwithstanding replacement of the Collateral Agent pursuant to this Section 11.07(e), the Company’s obligations under this Section 11.07 and Section 11.12 shall continue for the benefit of the retiring Collateral Agent.

(f) Except as otherwise explicitly provided herein or in the Security Documents, neither the Collateral Agent nor any of its officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own willful misconduct, gross negligence or bad faith.

(g) The Trustee is authorized and directed by the Holders and the Holders by acquiring the Securities and deemed to have authorized the Trustee, as applicable, to (i) enter into the Security Documents, (ii) bind the Holders on the terms as set forth in the Security Documents and (iii) perform and observe its obligations under the Security Documents. The Collateral Agent is authorize and directed by the Trustee and the Holders and the Holders by acquiring the Securities and deemed to have authorized the Collateral Agent to (i) enter into the Security Documents, (ii) bind the Trustee and the Holders on the terms as set forth in the Security Documents and (iii) perform and observe its obligations under the Security Documents.

(h) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by the Company and the Guarantors or is cared for, protected or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Grantor’s property constituting collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to the Collateral Agent pursuant to this Indenture or any Security Document, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Collateral Agent may act

Any request by the Company pursuant to the preceding sentence shall be evidenced by a certificate from an officer of the Company which certificate shall certify that (1) the Permitted Liens in question do not materially adversely affect or impair (A) the business operations of the Company and its Restricted Subsidiaries as a whole or (B) the validity or priority of the Lien of the Mortgages on the balance of the Mortgaged Property and (2) the applicable non-disturbance agreement, consent or other agreement provides that the Permitted Liens in question are subordinate to the Lien in favor of the Collateral Agent on the Mortgaged Property.

The undersigned represents and warrants to you that:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to the Securities in the normal course of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment.

2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is one year after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Company, (b) pursuant to a registration statement that has been declared effective under the Securities Act, (c) in a transaction complying

with the requirements of Rule 144A under the Securities Act (“Rule 144A”), to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Securities of $250,000, or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company, the Registrar and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company, the Registrar and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Company, the Registrar and the Trustee.
