All other TIA terms used in this Indenture that are defined by the TIA, defined by the TIA reference to another statute or defined by Commission rule and not otherwise defined herein have the meanings assigned to them therein.

(8) the words “including,” “includes” and similar words shall be deemed to be followed by “without limitation”;

(9) accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this Indenture;

(10) the amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof in the case of any other Indebtedness;

(11) for purposes of determining compliance with any U.S. dollar-denominated restriction contained in this Indenture, the U.S. dollar-equivalent amount 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 Indebtedness, or first committed, in the case of revolving credit Indebtedness, or made, in the case of Investments or other amounts; 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 refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced;

(13) unless otherwise specified herein, all accounting terms used herein shall be interpreted, all accounting determinations hereunder shall be made, and all financial statements required to be delivered hereunder shall be prepared in accordance with GAAP;

(14) “$” and “U.S. Dollars” each refer to United States dollars, or such other money of the United States of America that at the time of payment is legal tender for payment of public and private debts;

(15) whenever in this Indenture there is mentioned, in any context, principal, interest or any other amount payable under or with respect to any Securities, such mention shall be deemed to include mention of the payment of Additional Interest, to the extent that, in such context, Additional Interest is, was or would be payable in respect thereof;

(16) the amount of interest for each day that the Securities are outstanding (the “Daily Interest Amount”) will be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of the Securities. The amount of interest to be paid on the Securities for each Interest Period will be calculated by adding the Daily Interest Amounts for each day in the Interest Period; and

(17) all percentages resulting from any calculations of interest due on the Securities will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 9.876545% (or 0.09876545) being rounded to 9.87655% (or 0.0987655)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

ARTICLE TWO

THE SECURITIES

SECTION 2.01. Form, Dating and Terms.

(a) The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is unlimited. The Securities issued on the date hereof will be in an aggregate principal amount not to exceed $100,000,000 upon execution of this Indenture, or from time to time thereafter, as may be executed by the Company and delivered to the Trustee for authentication, and as the Trustee shall, upon receipt of a Company Order, authenticate and deliver to or upon the written order of the Company, signed by its chief Executive Officer, its President, its Chief Operating Officer or any Vice President (whether or not designated by a number or numbers or word or words added before or after the title “Vice President”), without any further action by the Company thereafter. In addition, the Company may issue, from time to time in accordance with the provisions of this Indenture, additional Securities. Furthermore, Securities may be authenticated and delivered upon registration or transfer, or in lieu of, other Securities pursuant to Section 2.06, 2.07, 2.10 or 9.05 or in connection with an Asset Sale Offer pursuant to Section 4.11, an Excess Cash Flow Offer pursuant to Section 4.12 or a Financing Event Offer pursuant to Section 4.13.

The Securities shall be known and designated as “Senior Secured Floating Rate Notes Due 2012” of the Company.

The Securities shall be considered collectively as a single class for all purposes of this Indenture. Holders of the Securities will vote and consent together on all matters to which such Holders are entitled to vote or consent as one class, and none of the Holders of the Securities shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

(b) The Securities issued on the Issue Date are being offered and sold by the Company pursuant to the Securities Purchase Agreement and the Registration Rights Agreement.

The principal of (and premium, if any) and interest on the Securities shall be payable at the office or agency of the Company maintained for such purpose at the Corporate Trust Office, or at such other office or agency of the Company as may be maintained for such purpose pursuant to Section 2.03; provided, however, that, at the option of the Company, each installment of interest may be paid by (i) check mailed to addresses of the Persons entitled thereto as such addresses shall appear on the Securities Register or (ii) wire transfer to an account located in the United States maintained by the payee. Payments in respect of Securities represented by a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depositary. Payments in respect of Securities represented by Definitive Securities (including principal, premium, if any, and interest) held by a Holder will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than three Business Days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

The Securities and the Trustee’s certificate of authentication to be borne by such Securities shall be substantially in the form set forth in Exhibit B. The terms and provisions contained in the Form of Initial Security attached as Exhibit B hereto shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

Any of the Securities may have such letters, numbers or other marks of identification and such notations, legends, endorsements (which may include a schedule to reflect increases or decreases in principal amount of a Global Security) or changes as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required by the custodian or the Depositary as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Securities may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Securities are subject.

So long as the Securities are eligible for book-entry settlement with the Depositary, or unless otherwise required by law, or otherwise contemplated by Section 2.01(f), all of the Securities may be represented by one or more Securities in global form registered in the name of the Depositary or the nominee of the Depositary (each, a “Global Security”). The transfer and exchange of beneficial interests in any such Global Security shall be effected through the Depositary in accordance with this Indenture and the applicable procedures of the Depositary. Such Global Security shall bear the Global Legend.

Any Global Security shall represent such of the outstanding Securities as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Securities from time to time endorsed thereon and that the aggregate principal amount of outstanding Securities represented thereby may from time to time be increased or reduced to reflect redemptions, repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the principal amount of outstanding Securities represented thereby shall be made by the Trustee or the custodian, at the direction of the Trustee, in such manner and upon instructions given by the holder of such Securities in accordance with this Indenture. Payment of the principal amount of and interest on any Global Security shall be made to the holder of such Security.

(c) Denominations. The Securities shall be issuable only in fully registered form, without interest coupons, and only in denominations of $2,000 and an integral multiple of $1,000 thereof.

(d) Restrictive Legends. Unless and until a Security is transferred under an effective registration statement, such Security shall bear the Restricted Securities Legend on the face thereof. By its acceptance of any Security bearing the Restricted Securities Legend, each Holder of such Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and in the Restricted Securities Legend and agrees that it will transfer such Security only as provided in this Indenture.

(e) Book-Entry Provisions.

(i) This Section 2.01(e) shall apply only to Global Securities deposited with the Trustee, as custodian for the Depositary.

(ii) Each Global Security initially shall (A) be registered in the name of the Depositary for such Global Security or the nominee of the Depositary, (B) be delivered to the Trustee as custodian for the Depositary and (C) bear legends as set forth in Section 2.01(d).

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

(iv) In connection with any transfer of a portion of the beneficial interest in a Global Security pursuant to subsection (f) of this Section 2.01 to beneficial owners who are required to hold Definitive Securities, the Trustee shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interest in the Global Security to be transferred, and the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and make available for delivery, one or more Definitive Securities of like tenor and amount.

(v) In connection with the transfer of an entire Global Security to beneficial owners pursuant to subsection (f) of this Section 2.01, such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and make available for delivery, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations.

(vi) The registered Holder of a Global Security may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

(vii) Any Holder of a Global Security shall, by acceptance of such Global Security, 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.

(f) Definitive Securities.

(i) Except as provided below, owners of beneficial interests in Global Securities will not be entitled to receive Definitive Securities. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Definitive Securities in exchange for their beneficial interests in a Global Security upon written request in accordance with the Depositary’s and the Registrar’s procedures. In addition, Definitive Securities shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Security if (A) the Depositary notifies the Company at any time that it is unwilling or unable to continue as depositary for such Global Security or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when the Depositary is required to be so registered in order to act as depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice or, (B) the Company in its sole discretion executes and delivers to the Trustee and Registrar an Officers’ Certificate stating that such Global Security shall be so exchangeable or (C) an Event of Default has occurred and is continuing and the Registrar and the Trustee have received a written request from the Depositary. In the event of the occurrence of any of the events specified in clause (A), (B) or (C) of the preceding sentence, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Securities in fully registered form without interest coupons.

(ii) Any Definitive Security delivered in exchange for an interest in a Global Security pursuant to Section 2.01(e)(iv) or (v) shall, except as otherwise provided by Section 2.06(c), bear the applicable legend regarding transfer restrictions applicable to the Definitive Security set forth in Section 2.01(d).

(iii) In connection with the exchange of a portion of a Definitive Security for a beneficial interest in a Global Security, the Trustee shall, upon receipt of a Company Order, cancel such Definitive Security, and the Company shall execute, and the Trustee shall authenticate and make available for delivery, to the transferring Holder a new Definitive Security representing the principal amount not so transferred.

SECTION 2.02. Execution and Authentication.

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 Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid and shall not be entitled to any benefit under this Indenture until an authorized signatory of the Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Indenture. A Security shall be dated the date of its authentication.

At any time and from time to time after the execution and delivery of this Indenture, the Trustee shall authenticate and make available for delivery Securities for original issue on the Issue Date in an aggregate principal amount of $100,000,000 upon a written order of the Company signed by an Officer of the Company (the “Company Order”). Such Company Order shall specify whether the Securities will be in the form of Definitive Securities or Global Securities, the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities. Any such appointment shall be evidenced by an instrument signed by a Responsible Officer of the Trustee, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

For the avoidance of doubt, whenever in this Indenture an action of the Trustee requires a Company Order to perform such action and such action is otherwise required by the Trustee, the Company shall promptly execute and deliver such Company Order to the Trustee.

SECTION 2.03. Registrar and Paying Agent.

The Company shall maintain (a) an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”), (b) an office or agency where the Securities may be presented for payment (the “Paying Agent”) and (c) an office or agency where notices and demands to or upon the Company, if any, in respect of the Securities and this Indenture may be served. The Registrar shall keep a register of the Securities and of their transfer and exchange (the “Securities Register”). The Company may have one or more co-registrars and one or more additional Paying Agents. The term “Registrar” includes any co-registrars. The Company or any Affiliate thereof may act as Registrar or Paying Agent. The term “Paying Agent” includes any additional paying agent.

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 provisions 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 each such agent. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such and shall be entitled to appropriate compensation therefor in accordance with Section 7.07.

The Company initially appoints the Corporate Trust Office of the Trustee to act as Registrar, Paying Agent and agent for service of notices and demands in connection with the Securities and this Indenture.

The Company may change the paying agents or the registrars without prior notice to the Holders. Any of the Company’s Wholly Owned Subsidiaries organized in the United States may act as Paying Agent or Registrar.

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.

SECTION 2.04. Paying Agent To Hold Assets in Trust.

The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium or interest on the Securities (whether such money has been paid to it by the Company, one or more of the Guarantors or any other obligor on the Securities) and the Company and each Paying Agent shall notify the Trustee in writing of any Default by the Company (or any other obligor on the Securities) in making any such payment. Money held in trust by a Paying Agent need not be segregated except as required by law and in no event shall a Paying Agent be liable for any interest on any money received by it hereunder. If any Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and account for any funds disbursed and the Trustee may at any time during the continuance of any Event of Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith all money so held by it to the Trustee and to account for any funds disbursed. Upon complying with this Section 2.04, the Paying Agent (if other than a Subsidiary of the Company) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Securities.

SECTION 2.05. Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, or to the extent otherwise required under the TIA, the Company, on its own behalf and on behalf of each of the Subsidiaries, if any, shall furnish or cause the Registrar to furnish to the Trustee, in writing at least two (2) Business Days prior to each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders, which list may be conclusively relied upon by the Trustee.

SECTION 2.06. Transfer and Exchange.

(a) Restricted Securities Legend. Upon the transfer, exchange or replacement of Securities not bearing a Restricted Securities Legend, the Registrar shall deliver Securities that do not bear a Restricted Securities Legend. Upon the transfer, exchange

or replacement of Securities bearing a Restricted Securities Legend, the Registrar shall deliver only Securities that bear a Restricted Securities Legend unless (i) a Security is being transferred pursuant to the Shelf Registration Statement or other effective registration statement or (ii) there is delivered to the Registrar an Opinion of Counsel satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(b) The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.01 or this Section 2.06. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Registrar.

(i) To permit registrations of transfers and exchanges, at the Registrar’s request, the Company shall, subject to the other terms and conditions of this Article Two, execute and the Trustee shall, upon receipt of a Company Order, authenticate Definitive Securities and Global Securities.

(ii) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company may require the Holder to pay a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charges payable upon exchange or transfer pursuant to Section 9.05).

(iii) The Company (and the Registrar) shall not be required to register the transfer of or exchange of any Security (1) for a period beginning 15 days before the mailing of a notice of an offer to repurchase or redeem Securities and ending at the close of business on the day of such mailing, and (2) during an Asset Sale Offer, an Excess Cash Flow Offer or a Financing Event Offer, if such Security is tendered pursuant to such Asset Sale Offer, Excess Cash Flow Offer or Financing Event Offer and not withdrawn.

(iv) Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent or 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, premium, if any, and interest on such Security and for all other purposes whatsoever, including the transfer or exchange of such Security, whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

(v) Any Definitive Security delivered in exchange for an interest in a Global Security pursuant to Section 2.01(f) shall, except as otherwise provided by Section 2.06(a), bear the applicable legend regarding transfer restrictions applicable to the Global Security set forth in Section 2.01(d).

(vi) 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.

(d) No Obligation of the Trustee.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in, the Depositary or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount or delivery of any Securities (or other security or property) under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders in respect of the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

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

(e) No Transfer Prior to May 1, 2008. Notwithstanding anything in this Indenture to the contrary, none of the Securities, whether represented in the form of a Definitive Security or Global Security, nor any interest therein, shall be transferred by the initial beneficial Holders thereof without the prior written consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed) prior to May 1, 2008; provided that such initial beneficial Holders may transfer such Securities to any Permitted Holder (which Permitted Holder shall then be bound by this provision as though it were an initial beneficial Holder) without the prior written consent of the Company.

SECTION 2.07. Mutilated, Destroyed, Lost or Stolen Securities.

If a mutilated Security is surrendered to the Registrar or the Trustee, or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall, upon receipt of a Company Order, 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 Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to the Company or the Trustee 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 Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond satisfactory to the Trustee sufficient to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Security is replaced, and, in the absence of notice to the Company, any Subsidiary or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and, upon receipt of a Company Order, the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

The Company may charge such Holder for the Company’s reasonable out-of-pocket expenses in replacing such Security, and may require the payment by the Holder of a sum sufficient to cover any tax or other governmental charge that may reasonably be imposed in relation thereof, and the Trustee may charge the Company for the Trustee’s expenses (including reasonable attorneys’ fees and disbursements) in replacing such Security.

Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, any Subsidiary (if applicable) and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

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

SECTION 2.08. Outstanding Securities.

The Securities outstanding at any time are all the Securities that have been authenticated by the Trustee except (a) those canceled by it, (b) those delivered to it for cancellation, (c) to the extent set forth in Section 8.01 and Section 8.02, on or after the date the conditions set forth in Section 8.01 or Section 8.02 have been satisfied and (d) those Securities described in this Section as not

outstanding. A Security does not cease to be outstanding in the event either of the Company or an Affiliate of the Company holds the Security, provided, however, that (i) for purposes of determining which are outstanding for consent or voting purposes hereunder, the provisions of Section 2.09 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Securities are present at a meeting of Holders of Securities for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Securities which a Responsible Officer of the Trustee actually knows to be held by the Company or an Affiliate of the Company shall not be considered outstanding.

If a Security is replaced pursuant to Section 2.07 (other than a mutilated Security surrendered for replacement), it ceases to be outstanding and interest on it ceases to accrue unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser in whose hands such Security is a legal, valid and binding obligation of the Company. A mutilated Security ceases to be outstanding upon surrender of such Security and replacement thereof pursuant to Section 2.07.

If the principal amount of any Security is considered paid under Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a Redemption Date or the Maturity Date the Trustee or Paying Agent (other than the Company or an Affiliate thereof) holds U.S. Legal Tender or U.S. Government Securities sufficient to pay all of the principal, premium, if any, and accrued interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and the Trustee or Paying Agent is not 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 2.09. Treasury Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or any of its Affiliates shall be disregarded, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows are so owned shall be disregarded. Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination.

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 Trustee shall, upon receipt of a Company Order, authenticate temporary Securities. Temporary Securities shall be substantially in the form, and shall carry all rights, of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare

and the Trustee shall, upon receipt of a Company Order, authenticate Definitive Securities. Notwithstanding the foregoing, so long as the Securities are represented by a Global Security, such Global Security may be in typewritten form. After the preparation of Definitive Securities, the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the temporary Securities at any office or agency maintained by the Company for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and make available for delivery in exchange therefor, one or more Definitive Securities representing an equal principal amount of Securities. Until so exchanged, the Holder of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Securities.

SECTION 2.11. Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent (other than the Company or a Subsidiary), and no one else, shall cancel and, at the written direction of the Company, shall dispose of all Securities surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. Subject to Section 2.07, the Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. If the Company or any Guarantor shall acquire any of the Securities, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11.

At such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, transferred, redeemed, repurchased or canceled, such Global Security shall be returned by the Depositary to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for Definitive Securities, transferred in exchange for an interest in another Global Security, redeemed, repurchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the custodian for such Global Security) with respect to such Global Security, by the Trustee or the custodian, to reflect such reduction.

SECTION 2.12. Payment of Interest; Defaulted Interest.

Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more predecessor Securities) is registered at the close of business on the Record Date for such payment at the office or agency of the Company maintained for such purpose pursuant to Section 2.03.

Any interest on any Security which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the regular record date, and such

defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate per annum borne by the Securities plus 2% per annum (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date (not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest, which date shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for under Section 12.02, not less than 10 days prior to such Special Record Date. Notice shall include the subsequent special Record Date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements (if applicable) of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this sentence, such manner of payment shall be deemed in its sole discretion practicable by the Trustee.

SECTION 2.13. CUSIP, ISIN and Common Code Numbers.

The Company in issuing the Securities may, at its option, use CUSIP, Common Code or ISIN numbers and, if so, the Trustee shall use CUSIP, Common Code or ISIN 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 or accuracy 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 any such redemption shall not be affected by any defect in or omission of such CUSIP, Common Code or ISIN number. The Company shall promptly notify the Trustee in writing of any change in the CUSIP, Common Code or ISIN number.

SECTION 2.14. Deposit of Moneys.

Prior to 10:00 a.m. New York City time, on each Interest Payment Date, the Maturity Date and each Redemption Date, the Company shall deposit with the Paying Agent in immediately available funds U.S. Legal Tender sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date and Redemption Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date and Redemption Date, as the case may be. The principal and interest on Global Securities shall be payable to the Depository or its nominee, as the sole registered owner and the sole Holder of the Global Securities represented thereby. The principal and interest on Definitive Securities shall be payable, in person, at the office of the applicable Paying Agent, by mail or by wire if elected under Section 2.01 hereof.

SECTION 2.15. Calculation of principal amount of Securities.

The aggregate principal amount of the Securities, at any date of determination, shall be the principal amount of the Securities at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the 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, and Section 2.08 of this Indenture. Any such calculation made pursuant to this Section 2.15 shall be made by the Company and delivered to the Trustee pursuant to an Officers’ Certificate.

The Company shall give notice of redemption to the Paying Agent and Trustee at least 30 days but not more than 60 days before the Redemption Date, together with an Officers’ Certificate stating that such redemption will comply with the conditions contained herein.

SECTION 3.02. Selection of Securities to be Redeemed.

If less than all of the Securities are to be redeemed at any time, the Trustee will select Securities for redemption as follows:

(1) if the Securities are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Securities are listed; or

(2) if the Securities are not listed on any securities exchange, on a pro rata basis, by lot or by such method as the Trustee deems fair and appropriate.

No Securities of $2,000 or less shall be redeemed in part.

SECTION 3.03. Notice of Redemption.

At least 30 days but not more than 60 days before a Redemption Date, the Company shall send a notice of redemption by electronic transmission or by first class mail, postage prepaid, to each Holder whose Securities are to be redeemed at its registered address except that redemption notices may be sent more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the Securities or a satisfaction and discharge of this Indenture. At the Company’s request, the Trustee shall forward the notice of redemption in the Company’s name and at the Company’s expense; provided that in such case, the Trustee has received notice from the Company at least 45 days, but not more than 60 days (except as provided in the previous sentence), before a Redemption Date (unless a shorter notice shall be agreed to by the Trustee). Securities called for redemption become irrevocably due on the date fixed for redemption. On and after the Redemption Date, interest ceases to accrue on Securities or portions of them called for redemption. Each notice of redemption shall identify the Securities (including the CUSIP number) to be redeemed and shall state:

(1) the Redemption Date;

(2) the Redemption Price and the amount of accrued interest, if any, to be paid;

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

(4) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price, plus accrued interest, if any;

(5) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Securities is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Securities redeemed;

(6) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, and upon surrender of such Security, a new Security or Securities in aggregate principal amount equal to the unredeemed portion thereof will be issued;

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

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

(9) 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; and

(10) the Section of the Securities pursuant to which the Securities are to be redeemed.

The notice, if sent in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Security designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Security. Notices of redemption may not be conditional.

SECTION 3.04. Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.03, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price plus accrued interest, if any. Upon surrender to the Trustee or Paying Agent, such Securities called for redemption shall be paid at the Redemption Price (which shall include accrued interest thereon to the Redemption Date), but installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates. On and after the Redemption Date interest shall cease to accrue on Securities or portions thereof called for redemption.

SECTION 3.05. Deposit of Redemption Price.

With respect to the Securities, prior to 10:00 a.m., New York 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) U.S. Legal Tender and/or U.S. Government Securities 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 called for redemption that have been delivered by the Company to the Trustee for cancellation. On and after the Redemption Date, interest shall cease to accrue on the 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.

SECTION 3.06. Securities Redeemed in Part.

If any Security is to be redeemed in part only, the notice of redemption that relates to such Security shall state the portion of the principal amount thereof to be redeemed. A new Security in principal amount equal to the unredeemed portion of the original Security shall be issued in the name of the Holder thereof upon cancellation of the original Security.

(2) in the case of Asset Sales involving consideration in excess of $2,000,000, the fair market value is determined in good faith by the Company’s Board of Directors; and

(3) at least 75% of the consideration received in the Asset Sale by the Company or such Subsidiary is in the form of cash or Cash Equivalents.

For purposes of clause (3) above, the amount of (i) any liabilities (as shown on the Company’s or such Subsidiary’s most recent balance sheet-or in the notes thereto) of the Company or any Subsidiary (other than liabilities that are by their terms subordinated to the Securities or the Guarantees) that are assumed by the transferee of any such assets and from which the Company

and all Subsidiaries have been validly released by all creditors in writing, (ii) any securities, notes or other obligations received by the Company or such Subsidiary from such transferee that are converted by the Company or such Subsidiary into cash (to the extent of the cash received) within 30 days following the closing of such Asset Sale and (iii) solely with respect to Asset Sales consisting of leases to third parties, the total payments to be received by the Company and its Subsidiaries under any such lease shall be used as the basis for determining compliance with clause (3) above.

(b) Within 365 days after the receipt by the Company or any Subsidiary of Net Cash Proceeds from any Asset Sale, for so long as no Default or Event of Default shall have occurred and be continuing (as certified by the Company to the Trustee in the form of an Officers’ Certificate), the Company may apply those Net Cash Proceeds, at its option:

(1) to an investment (or binding agreement to invest as provided for below) in (A) any one or more businesses; provided that such investment in any business is in the form of the acquisition of Capital Stock and results in the Company or one of its Subsidiaries owning an amount of the Capital Stock of such business such that it constitutes a Subsidiary, (B) capital expenditures or (C) other assets, in each of (A), (B) and (C), used or useful in a business having property or assets of a similar nature or type as, or engaged in a similar business as, the Company and its Subsidiaries; and/or

(2) to an investment in (A) any one or more businesses; provided that such investment in any business is in the form of the acquisition of Capital Stock and it results in the Company or one of its Subsidiaries owning an amount of the Capital Stock of such business such that it constitutes a Subsidiary, (B) properties or (C) other assets that, in each of (A), (B) and (C), replace the businesses, properties and assets that are the subject of such Asset Sale;

provided, that in the case of clauses (1) and (2) above, (i) a binding agreement shall be treated as a permitted application of Net Cash Proceeds from the date of such commitment until the earlier of (x) the date on which such investment is consummated and (y) the 180^th day following the expiration of the aforementioned 365-day period; (ii) that any such binding agreement to invest shall be subject to only customary conditions (other than financing); and (iii) to the extent the assets or property that were the subject of such Asset Sale were included in Collateral, then the Company shall use commercially reasonable efforts to ensure that Collateral Agent shall promptly receive a valid and perfected first priority lien on any business, property, assets or Capital Stock so acquired.

(c) On the 366^th day after an Asset Sale (or such later date after giving effect to the proviso in the preceding paragraph) or, in each such case, such earlier date, if any, as the Board of Directors determines by Board Resolution not to apply or invest any amount of Net Cash Proceeds relating to such Asset Sale in accordance with the preceding paragraph (the “Asset Sale Redemption Date” ), the Company shall apply such remaining amount of Net Cash Proceeds toward the redemption of the Securities as set forth in this Section 4.11.

On the Asset Sale Redemption Date, the Company shall make an offer (an “Asset Sale Offer”) to all Holders to purchase, on a pro rata basis, the maximum principal amount of Securities that may be purchased out of the remaining Net Cash Proceeds from such Asset Sale (the “Asset Sale Offer Amount” ). The offer price in any Asset Sale Offer will be equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Asset Sale Payment” ), and will be payable in cash.

Pending the final application of any Net Cash Proceeds, the Company shall be entitled to temporarily invest the Net Cash Proceeds in any manner that is not prohibited by this Indenture.

If any Net Cash Proceeds remain after consummation of an Asset Sale Offer, the Company shall be entitled to use those Net Cash Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities tendered into such Asset Sale Offer exceeds the amount of Net Cash Proceeds, the Trustee shall select the Securities to be purchased on a pro rata basis with adjustments so that only Securities in multiples of $1,000 principal amount will be purchased. Upon completion of each Asset Sale Offer, the amount of Net Cash Proceeds will be reset at zero.

Upon the commencement of an Asset Sale Offer, the Company shall send, electronically or by first class mail, a notice to the Trustee and to each Holder at its registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Securities pursuant to the Asset Sale Offer. Any Asset Sale Offer shall be made to all Holders. The notice, which shall govern the terms of the Asset Sale Offer, shall state:

(1) that the Asset Sale Offer is being made pursuant to this Section 4.11;

(2) the Asset Sale Offer Amount, the Asset Sale Payment and the date on which Securities tendered and accepted for payment shall be purchased, which date shall be at least 30 days and no later than 60 days from the date such notice is mailed (the “Asset Sale Payment Date” );

(3) that any Securities not tendered or accepted for payment shall continue to accrue interest;

(4) that, unless the Company defaults in making such payment, any Securities accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest after the Asset Sale Payment Date;

(5) that Holders electing to have a Security purchased pursuant to any Asset Sale Offer shall be required to surrender the Security, with the form entitled “Option of Holder To Elect Purchase” on the reverse of the Security completed, or transfer such Security by book-entry transfer, to the Paying Agent at the address specified in the notice at least three Business Days before the Asset Sale Payment Date;

(6) that Holders shall be entitled to withdraw their election if the Paying Agent receives, not later than the second Business Day prior to the Asset Sale Payment Date, a notice setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing such Holder’s election to have such Security purchased;

(7) that, if the aggregate principal amount of Securities surrendered by Holders exceeds the Asset Sale Offer Amount, the Trustee shall select the Securities to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Securities in denominations of $1,000 or integral multiples of $1,000 shall be purchased); and

(8) that Holders whose Securities were purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered (or transferred by book-entry transfer); provided that such Securities shall be in denominations of $2,000 or integral multiples $1,000.

On the Asset Sale Payment Date, the Company shall, to the extent lawful: (1) accept for payment all Securities or portions thereof properly tendered pursuant to the Asset Sale Offer; (2) deposit with the Paying Agent U.S. Legal Tender and/or U.S. Government Securities sufficient to pay the Asset Sale Payment in respect of all Securities or portions thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company. The Company shall publicly announce the results of the Asset Sale Offer on the Asset Sale Payment Date.

The Paying Agent shall promptly mail to each Holder who so tendered such Securities the Asset Sale Payment for such Securities, and the Trustee shall promptly authenticate pursuant to an Company Order and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each such new Security shall be in a principal amount of $2,000 or an integral multiple of $1,000. However, if the Asset Sale Payment Date is on or after an interest Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a Security is registered at the close of business on such Record Date, and no additional interest shall be payable to Holders who tender Securities pursuant to the Asset Sale Offer.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Securities pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.11, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.11 by virtue of such conflict.

SECTION 4.12. Redemption Using Excess Cash Flow.

Each such redemption shall be made on a date (an “Excess Cash Flow Redemption Date”) no later than 90 days after the earlier of

(i) the date on which the financial statements of the Company, for the fiscal year with respect to which such redemption is made, are required to be delivered to the Holders and (ii) the date such financial statements are actually delivered.

On the Excess Cash Flow Redemption Date, the Company shall make an offer (an “Excess Cash Flow Offer”) to all Holders to purchase, on a pro rata basis, the maximum principal amount of Securities that may be purchased out of 50% of the Excess Cash Flow (the “Excess Cash Flow Offer Amount”). The offer price in any Excess Cash Flow Offer will be equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase (the “Excess Cash Flow Payment”), and will be payable in cash.

If any Excess Cash Flow remains after consummation of an Excess Cash Flow Offer, the Company shall be entitled to use the Excess Cash Flow for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities tendered into such Excess Cash Flow Offer exceeds the amount of Excess Cash Flow, the Trustee shall select the Securities to be purchased on a pro rata basis with adjustments so that only Securities in multiples of $1,000 principle amount will be purchased. Upon completion of each Excess Cash Flow Offer, the amount of Excess Cash Flow will be reset at zero.

Upon the commencement of an Excess Cash Flow Offer, the Company shall send, electronically or by first class mail, a notice to the Trustee and to each Holder at its registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Securities pursuant to the Excess Cash Flow Offer. Any Excess Cash Flow Offer shall be made to all Holders. The notice, which shall govern the terms of the Excess Cash Flow Offer, shall state:

(1) that the Excess Cash Flow Offer is being made pursuant to this Section 4.12;

(2) the Excess Cash Flow Offer Amount, the Excess Cash Flow Payment and the date on which Securities tendered and accepted for payment shall be purchased, which date shall be at least 30 days and no later than 60 days from the date such notice is mailed (the “Excess Cash Flow Payment Date”);

(3) that any Securities not tendered or accepted for payment shall continue to accrue interest;

On the Financing Event Redemption Date, the Company shall make an offer (an “Financing Event Offer”) to all Holders to purchase, on a pro rata basis, the maximum principal amount of Securities that may be purchased out of the Net Cash Proceeds from such Financing Event (the “Financing Event Offer Amount”). The offer price in any Financing Event Offer will be equal to 100% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Financing Event Payment”), and will be payable in cash.

Pending the final application of any Net Cash Proceeds, the Company shall be entitled to temporarily invest the Net Cash Proceeds in any manner that is not prohibited by this Indenture.

If any Net Cash Proceeds remain after consummation of a Financing Event Offer, the Company shall be entitled to use those Net Cash Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities tendered into such Financing Event Offer exceeds the amount of Net Cash Proceeds, the Trustee shall select the Securities to be purchased on a pro rata basis, with adjustments so that only Securities in multiples of $1,000 principal amount will be purchased. Upon completion of each Financing Event Offer, the amount of Net Cash Proceeds will be reset at zero.

Upon the commencement of a Financing Event Offer, the Company shall send, electronically or by first class mail, a notice to the Trustee and to each Holder at its registered address. The notice shall contain all instructions and materials necessary to enable such Holder to tender Securities pursuant to the Financing Event Offer. Any Financing Event Offer shall be made to all Holders. The notice, which shall govern the terms of the Financing Event Offer, shall state:

(1) that the Financing Event Offer is being made pursuant to this Section 4.13;

(6) that Holders shall be entitled to withdraw their election if the Paying Agent receives, not later than the second Business Day prior to the Financing Event Payment Date, a notice setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing such Holder’s election to have such Security purchased;

(7) that, if the aggregate principal amount of Securities surrendered by Holders exceeds the Financing Event Offer Amount, the Trustee shall select the Securities to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Company so that only Securities in denominations of $1,000 or integral multiples in excess thereof of $1,000 shall be purchased); and

On the Financing Event Payment Date, the Company shall, to the extent lawful: (1) accept for payment all Securities or portions thereof properly tendered pursuant to the Financing Event Offer; (2) deposit with the Paying Agent U.S. Legal Tender and/or U.S. Government Securities sufficient to pay the Financing Event Payment in respect of all Securities or portions thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company.

However, if the

Financing Event Payment Date is on or after an interest Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest shall be paid to the Person in whose name a Security is registered at the close of business on such Record Date, and no additional interest shall be payable to Holders who tender Securities pursuant to the Financing Event Offer.

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Securities pursuant to a Financing Event Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.13, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.13 by virtue of such conflict.

then, and in any such event, the provisions of Section 6.02 shall apply.

SECTION 6.02. Acceleration.

If an Event of Default specified in paragraph (e) of Section 6.01 occurs with respect to the Company and is continuing, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding 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 Holder.

If any other Event of Default shall occur and be continuing, the Trustee or the Holders of at least 25% in principal amount of outstanding Securities under this Indenture may declare the principal of and accrued interest on such Securities to be due and payable by notice in writing to the Company and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration” (the “Acceleration Notice”), and the same shall become immediately due and payable.

At any time after a declaration of acceleration with respect to the Securities as described in the two preceding paragraphs, the Holders of a majority in principal amount of the Securities may rescind and cancel such declaration and its consequences:

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

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

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

(4) if the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

(5) in the event of the cure or waiver of an Event of Default of the type described in clause (i) or (ii) of paragraph (f) of Section 6.01, if the Trustee shall have received an Officers’ Certificate and an Opinion of Counsel that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 6.03. Other Remedies.

(a) If a Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

(b) 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 Securityholder in exercising any right or remedy accruing upon a Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

(c) In the event of any Event of Default specified in paragraph (d) of Section 6.01, such Event of Default and all consequences thereof (excluding, however, any resulting payment default) will be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose, the Company delivers an Officers’ Certificate to the Trustee stating that (i) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (ii) 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 (iii) the default that is the basis for such Event of Default has been cured.

(d) Holders may not enforce this Indenture or the Securities except as provided in this Indenture and under the TIA. Subject to the provisions of this Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under this Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee indemnity satisfactory to it.

SECTION 6.04. Waiver of Defaults.

Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of a majority in aggregate principal amount of Securities at the time outstanding may on behalf of the Holders of all the Securities waive any Default with respect to such Securities and its consequences by providing written notice thereof to the Company and the Trustee, except a Default (1) in the payment of interest on or the principal of any Security or (2) in respect of a covenant or provision hereof which under this Indenture cannot be modified or amended without the consent of the Holder of each outstanding Security affected. In the case of any such waiver, the Company, the Trustee and the Holders will be restored to their former positions and rights under this Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereto.

SECTION 6.05. Control by Majority.

The Holders of not less than a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. Subject to Section 7.01, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Securityholder, or that may involve the Trustee in personal liability; provided that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

In the event the Trustee takes any action or follows any direction pursuant to this Indenture, the Trustee shall be entitled to indemnification against any loss or expense caused by taking such action or following such direction.

SECTION 6.06. Limitation on Suits.

A Holder may not pursue any remedy with respect to this Indenture or the Securities unless:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

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

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

(4) the Trustee does not comply with the request within 45 days after receipt of the request and the offer and the provision of indemnity; and

(5) during such 45-day period the Holder or Holders of a majority in principal amount of the outstanding Securities do not give the Trustee a direction which, in the opinion of the Trustee, is inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder.

SECTION 6.07. Rights of Holders To Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on a Security, on or after the respective due dates expressed in such Security, 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 the Holder.

SECTION 6.08. Collection Suit by Trustee.

If a Default in payment of principal or interest specified in paragraph (a) of Section 6.01 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 of principal and accrued interest and fees remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum borne by the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relating to the Company, the Guarantors, their creditors or their property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. The Trustee shall be entitled to participate as a member of any official committee of creditors in the matters as it deems necessary or advisable.

SECTION 6.10. Priorities.

If the Trustee collects any money or property pursuant to this Article Six and any other money or property distributable in respect of the Company’s or any Guarantor’s Obligations under this Indenture after an Event of Default, it shall be applied in the following order:

FIRST: to the Trustee for amounts due under Section 7.07;

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

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

FOURTH: to the Company or, if applicable, the Guarantors, as their respective interests may appear.

The Trustee, upon prior notice to the Company, may fix a Record Date and payment date for any payment to Holders pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as 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 a Holder or Holders of more than 10% in principal amount of the outstanding Securities.

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 the other Indenture Documents 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.

SECTION 7.02. Rights of Trustee.

Subject to Section 7.01:

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any document (whether in its original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper Person.

In addition, the Trustee shall be permitted to engage in transactions with the Company; provided, however, that if the Trustee acquires any conflicting interest, as defined in TIA § 310(b), the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the Commission for permission to continue acting as Trustee or (iii) resign. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights.

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 or the Securities, shall not be accountable for the Company’s use of the proceeds from the sale of the Securities, shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee or any money paid to the Company pursuant to the terms of this Indenture and shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or any statement in the Securities other than the Trustee’s certificate of authentication. The Trustee makes no representations with respect to the effectiveness or adequacy of this Indenture.

SECTION 7.05. Notice of Default.

If an Event of Default occurs and is continuing and a Responsible Officer of the Trustee receives written notice of such Event of Default, the Trustee shall mail to each Holder notice of the uncured Event of Default within 30 days after such Event of Default occurs. Except in the case of an Event of Default in payment of principal of, or interest on, any Security, including an accelerated payment and the failure to make payment on the Asset Sale Payment Date pursuant to an Asset Sale Offer, the Excess Cash Flow Payment Date pursuant to an Excess Cash Flow Offer or the Financing Event Offer Payment Date pursuant to a Financing Event Offer, the Trustee may withhold the notice if and so long as the Board of Directors, the executive committee, or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interest of the Holders.

SECTION 7.06. Reports by Trustee to Holders.

Within 60 days after each March 31 beginning with March 31, 2008, the Trustee shall, to the extent that any of the events described in TIA § 313(a) occurred within the previous twelve months, but not otherwise, send to each Holder a brief report dated as of such date that complies with TIA § 313(a). The Trustee also shall comply with TIA §§ 313(b), 313(c) and 313(d).

A copy of each report at the time of its delivery to Holders shall be sent to the Company and filed with the Commission and each securities exchange, if any, on which the Securities are listed.

The Company shall notify the Trustee if the Securities become listed on any securities exchange or of any delisting thereof and the Trustee shall comply with TIA § 313(d).

SECTION 7.07. Compensation and Indemnity.

The Company and each Guarantor jointly and severally shall pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for its services hereunder. 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 upon request for all reasonable disbursements, expenses and advances (including out-of-pocket expenses incurred or made by it, including costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Securityholders and reasonable fees and expenses of counsel, including any fees or costs incurred pursuant to Section 4.06 and Section 4.14 hereof) incurred or made by it in addition to the compensation for its services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s gross negligence or willful misconduct. Such expenses shall include the reasonable fees and expenses of the Trustee’s agents and counsel and of all Persons not regularly in its employ.

The Company shall indemnify each of the Trustee or any predecessor Trustee and its agents, employees, officers, stockholders and directors for, and hold each of them harmless against, any and all loss, damage, claims, liability or expense, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it except for such actions to the extent caused by any gross negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this trust including the costs and expenses of enforcing this Indenture or a Guarantee against the Company or a Guarantor (including this Section 7.07) and the reasonable costs and expenses of defending itself against or investigating any claim or liability in connection with the exercise or performance of any of its rights, powers or duties hereunder (whether asserted by the Company, any Guarantor, any Holder or any other Person). Notwithstanding the foregoing, the Company and any Subsidiary, need not reimburse any expense or indemnify against any loss, liability or expense which is finally determined by a court of competent jurisdiction to have been incurred by the Trustee through the Trustee’s own willful misconduct or gross negligence.

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 against all Collateral and other money or property held or collected by the Trustee, in its capacity as Trustee.

When the Trustee incurs expenses or renders services after a Default specified in clause (i) or (ii) of paragraph (e) of Section 6.01 occurs, such expenses (including the reasonable charges and expenses of its counsel) and the compensation for such services shall be paid to the extent allowed under any Bankruptcy Law and are intended to constitute expenses of administration under any Bankruptcy Law.

Notwithstanding any other provision in this Indenture, the foregoing provisions of this Section 7.07 shall survive the satisfaction and discharge of the Securities, the termination for any reason of this Indenture or the appointment of a successor Trustee.

SECTION 7.08. Replacement of Trustee.

The Trustee may resign at any time by so notifying the Company in writing. The Holders of a majority in principal amount of the outstanding Securities may remove the Trustee by so notifying the Company and the Trustee and may appoint a successor Trustee, provided, that any such successor Trustee shall be an institution that regularly acts as a trustee in comparable transactions. The Company may remove the Trustee if:

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

(b) the Trustee is adjudged bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting as trustee hereunder.

If the Trustee resigns or 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 as described in the preceding paragraph, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall notify each Holder of such event and promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee, after payment of all sums then owing to the Trustee pursuant to Section 7.07. 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.

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

If the Trustee fails to comply with Section 7.10, unless the Trustee’s duty to resign is stayed as provided in TIA § 310(b), 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.

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

SECTION 7.09. Successor Trustee by Merger, Etc.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another Person, the resulting, surviving or transferee Person without any further act shall become the successor Trustee, if such resulting, surviving or transferee Person is otherwise qualified and eligible hereunder.

In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities in the name of the successor to the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee shall only apply to its successor or successors by merger, consolidation or conversion.

SECTION 7.10. Eligibility; Disqualification.

This Indenture shall always have a Trustee who satisfies the requirement of TIA §§ 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. In addition, if the Trustee is a Person included in a bank holding company system, the Trustee, independently of the bank holding company, shall meet the capital requirements of TIA § 310(a)(2). The Trustee shall comply with TIA § 310(b). The provisions of TIA § 310 shall apply to the Company and any other obligor of the Securities.

SECTION 7.11. Preferential Collection of Claims Against the Company.

The Trustee, in its capacity as Trustee hereunder, shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

SECTION 7.12. Trustee’s Application for Instruction from the Company.

Any application by the Trustee for written instructions from the Company may set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

SECTION 7.13. Paying Agents.

The Company shall cause each Paying Agent other than the Trustee to execute and deliver to it and the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 7.13:

(a) that it will hold all sums held by it as agent for the payment of principal of, or premium, if any, or interest on, the Securities (whether such sums have been paid to it by the Company or by any obligor on the Securities) in trust for the benefit of Holders of the Securities or the Trustee;

(b) that it will at any time during the continuance of any Event of Default, upon written request from the Trustee, deliver to the Trustee all sums so held in trust by it together with a full accounting thereof; and

(c) that it will give the Trustee written notice within three Business Days of any failure of the Company (or by any obligor on the Securities) in the payment of any installment of the principal of or interest on, the Securities when the same shall be due and payable.

SECTION 8.01. Termination of the Company’s Obligations.

The Company shall be entitled to terminate its obligations under the Securities and this Indenture, except those obligations referred to in the penultimate paragraph of this Section 8.01, if all Securities previously authenticated and delivered (other than destroyed, lost or stolen Securities which have been replaced or paid or Securities for whose payment U.S. Legal Tender or U.S. Government Securities, or a combination thereof, in such amount as is, in the opinion of a nationally recognized firm of independent public accountants, sufficient without consideration of reinvestment of such interest, to pay principal of, premium, if any, and interest on the outstanding Securities to maturity or redemption, has theretofore been deposited with the Trustee or the Paying Agent in trust or segregated and held in trust by the Company and thereafter repaid to the Company, as provided in Section 8.05) have been delivered to the Trustee for cancellation and the Company has paid all sums payable by it hereunder, or if:

(1) either (i) pursuant to Article Three, the Company shall have given notice to the Trustee and sent a notice of redemption to each Holder of the redemption of all of the Securities in accordance with the provisions hereof or (ii) all Securities have otherwise become or will become due and payable by reason of the delivering of a notice of redemption or otherwise within one (1) year hereunder;

(2) the Company shall have irrevocably deposited or caused to be deposited with the Trustee or a trustee satisfactory to the Trustee, under the terms of an irrevocable trust agreement, as trust funds in trust solely for the benefit of the Holders of that

purpose, U.S. Legal Tender, non-callable U.S. Government Securities, or a combination thereof, in such amount as is, in the opinion of a nationally recognized firm of independent public accountants, sufficient without consideration of reinvestment of such interest, to pay and discharge the entire Indebtedness on the Securities not delivered to the Trustee for cancellation for principal, premium, if any, and Additional Interest, if any, and accrued interest on the outstanding Securities to maturity or redemption (assuming that the interest rate on the Securities is that which is in effect on the date of the deposit); provided that the Trustee shall have been irrevocably instructed to apply such U.S. Legal Tender or U.S. Government Securities, or a combination thereof, to the payment of said principal, premium, if any, and interest with respect to the Securities;

(3) no Default or Event of Default with respect to this Indenture or the Securities shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit (other than a Default resulting from borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowing) and such deposit will not result in a breach or violation of, or constitute a default under, any material instrument to which the Company is a party or by which it is bound;

(4) the Company shall have paid all other sums payable by it hereunder; and

(5) the Company shall have delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Securities at maturity or the Redemption Date, as the case may be.

The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent providing for or relating to the termination of the Company’s obligations under the Securities and this Indenture have been complied with. Such Opinion of Counsel shall also state that such satisfaction and discharge does not result in a default under the any material agreement or instrument then known to such counsel that binds or affects the Company.

Subject to the next sentence and notwithstanding the foregoing paragraph, the Company’s obligations in Sections 2.03, 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 7.07, 8.05 and 8.06 shall survive until the Securities are no longer outstanding pursuant to the last paragraph of Section 2.08. After the Securities are no longer outstanding, the Company’s obligations in Section 7.07, Section 8.05 and Section 8.06 shall survive.

After such delivery or irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Company’s obligations under the Securities and this Indenture except for those surviving obligations specified above.

SECTION 8.02. Legal Defeasance and Covenant Defeasance.

(a) The Company shall be entitled, at its option and at any time, to elect to have either paragraph (b) or (c) below applied to all outstanding Securities upon compliance with the conditions set forth in Section 8.03.

(b) Upon the Company’s exercise under paragraph (a) hereof of the option applicable to this paragraph (b), the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03, be deemed to have been discharged from their obligations with respect to all outstanding Securities on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.04 hereof and the other Sections of this Indenture (with respect to such Securities) referred to in (i) and (ii) below, and to have satisfied all its other obligations under such Securities, the Security Documents and this Indenture (with respect to such Securities) and the Guarantors shall be deemed to have satisfied all of their obligations under the Guarantees, the Security Documents and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(i) the rights of Holders of outstanding Securities issued hereunder to receive payments in respect of the principal of, or interest on such Securities when such payments are due from the trust referred to below;

(ii) the Company’s obligations with respect to the Securities issued hereunder concerning issuing temporary Securities, registration of Securities, mutilated, destroyed, lost or stolen Securities and the maintenance of an office or agency for payment and money for security payments held in trust;

(iv) this Article Eight.

Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.02(b) notwithstanding the prior exercise of its option under Section 8.02(c) hereof.

(c) Upon the Company’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), the Company and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.03 hereof, be released from their obligations under the covenants contained in Sections 4.04, 4.05, 4.06, 4.07, 4.09 through 4.29 hereof with respect to the outstanding Securities on and after the date the conditions set forth in Section 8.03 are satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other

provision herein or in any other document and such omission to comply shall not constitute an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. In addition, upon the Company’s exercise under paragraph (a) hereof of the option applicable to this paragraph (c), subject to the satisfaction of the conditions set forth in Section 8.03 hereof, clauses (b), (c), (d), (e) (with respect to a Subsidiary), (f), (g) , (h) and (i) of Section 6.01 hereof shall not constitute Events of Default.

SECTION 8.03. Conditions to Legal Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.02(b) or Section 8.02(c) hereof to the outstanding Securities:

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the holders of the applicable Securities issued hereunder, cash in U.S. Legal Tender, non-callable U.S. Government Securities, or a combination thereof, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, or interest and premium and Additional Interest, if any, on the outstanding Securities issued hereunder on the Stated Maturity or on the applicable Redemption Date, as the case may be (assuming that the interest rate on the Securities is that which is in effect on the date of the deposit), and the Company must specify whether the Securities are being defeased to maturity or to a particular Redemption Date;

(2) in the case of an election under Section 8.02(b) hereof, the Company has delivered to the Trustee an Opinion of Counsel confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the respective outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;

(3) in the case of an election under Section 8.02(c) hereof, the Company has delivered to the Trustee an Opinion of Counsel confirming that the Holders of the respective outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant 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 Covenant Defeasance had not occurred;

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

borrowings) or insofar as Events of Default resulting from the borrowing of funds or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

SECTION 8.04. Application of Trust Money.

The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or U.S. Government Securities, deposited with it pursuant to this Article Eight, and shall apply the deposited U.S. Legal Tender or the money from U.S. Government Securities, in accordance with this Indenture to the payment of principal of and interest on the Securities. The Trustee shall be under no obligation to invest said U.S. Legal Tender or U.S. Government Securities, except as it may agree with the Company.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Legal Tender or U.S. Government Securities, deposited pursuant to Section 8.03 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities.

Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s request any U.S. Legal Tender or U.S. Government Securities, held by it as provided in Section 8.03 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.05. Repayment to the Company.

Subject to this Article Eight, the Trustee and the Paying Agent shall promptly pay to the Company upon request any excess U.S. Legal Tender or U.S. Government Securities, held by them at any time and thereupon shall be relieved from all liability with respect to such money. Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years; provided that the Trustee or such Paying Agent, before being required to make any payment, may, but shall not be obligated to, at the expense of the

Company cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to such money must look to the Company for payment as general creditors unless an applicable law designates another Person.

SECTION 8.06. Reinstatement.

If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Securities, in accordance with this Article Eight 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 shall be revived and reinstated as though no deposit had occurred pursuant to this Article Eight until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender and U.S. Government Securities, in accordance with this Article Eight; provided that if the Company has made any payment of interest on or principal of any 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 U.S. Legal Tender or U.S. Government Securities, held by the Trustee or Paying Agent.

(b) Notwithstanding Section 9.02(a), without the consent of each Holder, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not:

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

(d) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall send to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

SECTION 9.03. Compliance with TIA.

From the date on which this Indenture is qualified under the TIA, every amendment, waiver or supplement of this Indenture, the Securities or the Subsidiary Guarantees shall comply with the TIA as then in effect. This Section 9.03 shall not require this Indenture or the Trustee to be qualified under the TIA prior to the time such qualification is in fact required under the terms of the

TIA, nor shall it constitute any admission or acknowledgement by any party to the Indenture that any such qualification is required prior to the time such qualification is in fact required under the terms of the TIA.

SECTION 9.04. Revocation and Effect of Consents.

(a) Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to his Security or portion of his Security by notice to the Trustee or the Company received before the date on which the Trustee receives an Officers’ Certificate certifying that the Holders of the requisite principal amount of Securities have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.

(b) The Company shall be entitled to, but shall not be obligated to, fix a Record Date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver which record date shall be at least 30 days prior to the first solicitation of such consent. If a record date is fixed, then notwithstanding the last sentence of the immediately preceding paragraph, those Persons who were Securityholders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such Record Date. No such consent shall be valid or effective for more than 90 days after such Record Date. The Company shall inform the Trustee in writing of the fixed Record Date if applicable.

(c) After an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (1) through (10) of Section 9.02(b); provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of and interest on a Security, on or after the respective due dates expressed in such Security, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder.

ARTICLE TEN

COLLATERAL

SECTION 10.01. Collateral and Security Documents.

(a) To secure the due and punctual payment of the obligations of the Company under this Indenture and the Securities, the Company, the Guarantors, the Collateral Agent and the Trustee have entered into the Security Documents to create the security interests and related matters. The Trustee and the Company hereby acknowledge and agree that the Collateral Agent holds the Collateral in trust for the equal and ratable benefit of the Holders and the Trustee and the other parties secured under the Security Documents pursuant to the terms of the Security Documents.

(b) Each Holder, by accepting a Security, agrees to all of the terms and provisions of the Security Documents, as the same may be amended from time to time pursuant to the provisions of the Security Documents and this Indenture, and authorizes and directs each of the Trustee and the Collateral Agent to perform its obligations and exercise its rights under the Security Documents in accordance therewith; provided, however, that if any provisions of the Security Documents limit, qualify or conflict with the duties imposed by the provisions of the TIA, the TIA will control.

(c) As more fully set forth in, and subject to the provisions of, the Security Documents, the Secured Parties have rights in and to the Collateral which are equal and ratable with the rights that may be created in favor of the holders of any Refinancing Debt with respect to the Securities and certain other parties identified in the Security Documents.

(d) As among the Holders, the Collateral shall be held for the equal and ratable benefit of the Holders without preference, priority or distinction of any thereof over any other.

SECTION 10.02. Release of Collateral.

Collateral securing Obligations owed to the Holders may be released from the security interest created by the Security Documents at any time or from time to time in accordance with the provisions of the Security Documents and this Indenture. The release of any Collateral from the terms hereof and of the Security Documents or the release of, in whole or in part, the Liens created by the Security Documents, will not be deemed to impair the Lien on the Collateral in contravention of the provisions hereof if and

to the extent the Collateral or Liens are released pursuant to the applicable Security Documents and pursuant to the terms of this Article Ten. The Trustee and each of the Holders acknowledge that a release of Collateral or a Lien strictly in accordance with the terms of the Security Documents and of this Article Ten will not be deemed for any purpose to be an impairment of the Lien on the Collateral in contravention of the terms of this Indenture. To the extent applicable, the Company and each obligor on the Securities shall cause § 314(d) of the TIA relating to the release of property or securities from the Lien hereof and of the Security Documents to be complied with. Any certificate or opinion required by § 314(d) of the TIA may be made by an officer of the Company, except in cases which § 314(d) of the TIA requires that such certificate or opinion be made by an independent person.

SECTION 10.03. Certificates; Opinions.

The Company shall comply with TIA § 314(d), relating to, among other matters, the release of Collateral from the Lien of the Security Documents and Officers’ Certificates or other documents regarding fair value of the Collateral, to the extent such provisions are applicable. Any certificate or opinion required by TIA § 314(d) may be executed and delivered by an Officer of the Company to the extent permitted by TIA § 314(d).

ARTICLE ELEVEN

GUARANTEES

SECTION 11.01. Unconditional Guarantee.

Subject to the provisions of this Article Eleven, each of the Guarantors hereby, jointly and severally, unconditionally and irrevocably guarantees, as a primary obligor and not merely as a surety, on an unsubordinated basis to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Securities or the obligations of the Company or any other Guarantors to the Holders or the Trustee hereunder or thereunder: (a) (x) the due and punctual payment of the principal of, premium, if any, and interest on the Securities when and as the same shall become due and payable, whether at maturity, upon redemption or repurchase, by acceleration or otherwise, (y) the due and punctual payment of interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Securities (including interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding relating to the Company or any Guarantor, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) and (z) the due and punctual payment and performance of all other obligations of the Company and all other obligations of the other Guarantors (including under the Guarantees), in each case, to the Holders or the Trustee hereunder or thereunder (including amounts due the Trustee under Section 7.07 hereof), all in accordance with the terms hereof and thereof (collectively, the “Guarantee Obligations”); and (b) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, the due and punctual payment and performance of Guarantee Obligations in accordance with the terms of the extension or renewal, whether at maturity, upon redemption or repurchase, by acceleration or otherwise. Failing payment

when due of any amount so guaranteed, or failing performance of any other obligation of the Company to the Holders under this Indenture or under the Securities, for whatever reason, each Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. An Event of Default under this Indenture or the Securities shall constitute an event of default under the Guarantees, and shall entitle the Holders to accelerate the obligations of the Guarantors thereunder in the same manner and to the same extent as the obligations of the Company.

Each of the Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same, whether or not a Guarantee is affixed to any particular Security, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each of the Guarantors hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Guarantee shall not be discharged except by complete performance of the obligations contained in the Securities, this Indenture and the Guarantee. The Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Company or to any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or such Guarantor, any amount paid by the Company or such Guarantor to the Trustee or such Holder, the Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between it, on the one hand, and the Holders of Securities and the Trustee, on the other hand, (a) subject to this Article Eleven, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of the Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Guarantee.

SECTION 11.02. Limitation on Guarantor Liability.

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

SECTION 11.03. Execution and Delivery of Guarantee for Future Guarantors.

To further evidence its Guarantee set forth in Section 11.01, each Subsidiary that is required to become a Guarantor hereby agrees to execute a supplement to this Indenture or a Guarantee, substantially in the form of Exhibit E hereto, and deliver it to the Trustee. Such Guarantee or supplement to this Indenture shall be executed on behalf of each Guarantor by either manual or facsimile signature of one Officer or other person duly authorized by all necessary corporate action of each Guarantor who shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Guarantee shall not be affected by the fact that it is not affixed to any particular Security.

Each of the Guarantors hereby agrees that its Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Guarantee.

If an Officer of a Guarantor whose signature is on this Indenture or a Guarantee no longer holds that office at the time the Trustee authenticates the Security on which such Guarantee is endorsed or at any time thereafter, such Guarantor’s Guarantee of such Security shall nevertheless be valid.

The actual or constructive delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of each Guarantor.

SECTION 11.04. Release of a Guarantor.

(a) The Guarantee of a Guarantor will be released upon the sale, disposition or other transfer (including through merger or consolidation) of all of the Capital Stock (or any sale, disposition or other transfer of Capital Stock following which the applicable Guarantor is no longer a Subsidiary), or all or substantially all the assets, of the applicable Guarantor if such sale, disposition or other transfer is made in compliance with the applicable provisions of this Indenture. The Trustee shall execute an appropriate instrument prepared by the Company evidencing the release of a Guarantor from its obligations under its Guarantee upon receipt of a request by the Company or such Guarantor accompanied by an Officers’ Certificate and an Opinion of Counsel certifying as to the compliance with this Section 11.04; provided, however, that the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers’ Certificates of the Company.

(b) In addition, the Company shall not permit any Guarantor to consolidate with or merge with or into any person (other than the Company or another Guarantor) and shall not permit the conveyance, transfer or lease of substantially all of the assets of any Guarantor unless:

(A) (1) either: (a) the Guarantor is the surviving Person; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Guarantor) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State of the United States of America or the District of Columbia (such Person being herein called the “Successor Guarantor”);

(2) the Successor Guarantor (if other than the Guarantor) assumes by means of a supplemental indenture all the obligations of the Guarantor under its Guarantee, this Indenture and any Registration Rights Agreement; and

(3) immediately after such transaction no Default or Event of Default exists; or

(B) the transaction is made in compliance with Sections 4.11, 4.12 and 4.13.

Except as set forth in Article Four and this Section 11.04, nothing contained in this Indenture or in any of the Securities shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

SECTION 11.05. Waiver of Subrogation.

Until this Indenture is discharged and all of the Securities are discharged and paid in full, each Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Company that arise from the existence, payment, performance or enforcement of the Company’s obligations under the Securities, the Security Documents or this Indenture and such Guarantor’s obligations under the Guarantee, the Security Documents and this Indenture, in any such instance including any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Company, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including the right to take or receive from the Company, directly or indirectly, in cash or other assets or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders under the Securities, this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.05 is knowingly made in contemplation of such benefits.

SECTION 11.06. Immediate Payment.

Each Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all Guarantee Obligations owing or payable to the respective Holders upon receipt of a demand for payment therefor by the Trustee to such Guarantor in writing.

SECTION 11.07. No Setoff.

Each payment to be made by a Guarantor hereunder in respect of the Guarantee Obligations shall be payable in the currency or currencies in which such Guarantee Obligations are denominated, and shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

Subject to the provisions of Section 11.02, the obligations of each Guarantor hereunder are and shall be absolute and unconditional and any monies or amounts expressed to be owing or payable by each Guarantor hereunder which may not be recoverable from such Guarantor on the basis of a Guarantee shall be recoverable from such Guarantor as a primary obligor and principal debtor in respect thereof.

SECTION 11.09. Guarantee Obligations Continuing.

Subject to the other provisions of this Indenture, the obligations of each Guarantor hereunder shall be continuing and shall remain in full force and effect until all such obligations have been paid and satisfied in full. Each Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability hereunder and under any other instrument or instruments in such form as counsel to the Trustee may advise and as will prevent any action brought against it in respect of any default hereunder being barred by any statute of limitations now or hereafter in force and, in the event of the failure of a Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or other instruments as may from time to time become necessary or advisable, in the judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such Guarantor hereunder.

SECTION 11.10. Guarantee Obligations Not Reduced.

The obligations of each Guarantor hereunder shall not be satisfied, reduced or discharged solely by the payment of such principal, premium, if any, interest, fees and other monies or amounts as may at any time prior to discharge of this Indenture pursuant to Article Eight be or become owing or payable under or by virtue of or otherwise in connection with the Securities or this Indenture.

SECTION 11.11. Guarantee Obligations Reinstated.

The obligations of each Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced the obligations of any Guarantor hereunder (whether such payment shall have been made by or on behalf of the Company or by or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of the Company or any Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Company or any other Guarantor is stayed upon the insolvency, bankruptcy, liquidation or reorganization of the Company or such Guarantor, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Guarantor as provided herein.

SECTION 11.12. Guarantee Obligations Not Affected.

The obligations of each Guarantor hereunder shall not be affected, impaired or diminished in any way by any act, omission, matter or thing whatsoever, occurring before, upon or after any demand for payment hereunder (and whether or not known or consented to by any Guarantor or any of the Holders) which, but for this provision, might constitute a whole or partial defense to a claim against any Guarantor hereunder or might operate to release or otherwise exonerate any Guarantor from any of its obligations hereunder or otherwise affect such obligations, whether occasioned by default of any of the Holders or otherwise, including:

(1) any limitation of status or power, disability, incapacity or other circumstance relating to the Company or any other Person, including any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, winding-up or other proceeding involving or affecting the Company or any other Person;

(10) any other circumstance, including release of the Guarantor pursuant to Section 11.04 (other than by complete, irrevocable payment) that might otherwise constitute a legal or equitable discharge or defense of the Company under this Indenture, the Security Documents or the Securities or of a Guarantor in respect of its Guarantee hereunder.

SECTION 11.13. Waiver.

Without in any way limiting the provisions of Section 11.01, each Guarantor hereby waives notice of acceptance hereof, notice of any liability of any Guarantor hereunder, notice or proof of reliance by the Holders upon the obligations of any Guarantor hereunder, and diligence, presentment, demand for payment on the Company, protest, notice of dishonor or non-payment of any of the Guarantee Obligations, or other notice or formalities to the Company or any Guarantor of any kind whatsoever.

SECTION 11.14. No Obligation To Take Action Against the Company.

Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights or remedies against the Company or any other Person or any property of the Company or any other Person before the Trustee is entitled to demand payment and performance by any or all Guarantors of their liabilities and obligations under their Guarantees or under this Indenture.
