If an Officer of the Company or a Guarantor whose signature is on a Security no longer holds that office at the time the Security or the Notation of Guarantee, as the case may be, is authenticated, the Security or Notation of Guarantee shall be valid nevertheless.

A Security shall not be entitled to any benefit under this Indenture or any related Securities Guarantees or be valid or obligatory for any purpose until authenticated by the manual signature of an authorized signatory of the Trustee, which signature shall be conclusive evidence that the Security has been authenticated under this Indenture. Notwithstanding the foregoing, if any Security has been authenticated and delivered hereunder but never issued and sold by the Company, and the Company

delivers such Security to the Trustee for cancellation as provided in Section 2.11, together with a written statement (which need not comply with Section 12.05 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture or the related Securities Guarantees.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company (and, if applicable, the Notation of Guarantee for such series executed by each Guarantor with respect to such series) to the Trustee for authentication, and the Trustee shall authenticate and deliver such Securities for original issue upon a Company Order for the authentication and delivery of such Securities or pursuant to such procedures acceptable to the Trustee as may be specified from time to time by Company Order. Such order shall specify the amount of the Securities to be authenticated, the date on which the original issue of Securities is to be authenticated, the name or names of the initial Holder or Holders and any other terms of the Securities of such series not otherwise determined. If provided for in such procedures, such Company Order may authorize (1) authentication and delivery of Securities of such series for original issue from time to time, with certain terms (including, without limitation, the Maturity dates or dates, original issue date or dates and interest rate or rates) that differ from Security to Security and (2) may authorize authentication and delivery pursuant to oral or electronic instructions from the Company or its duly authorized agent, which instructions shall be promptly confirmed in writing.

If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions as permitted by Section 2.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive (in addition to the Company Order referred to above and the other documents required by Section 12.04) and (subject to Section 7.01) shall be fully protected in conclusively relying upon:

If all the Securities of any series are not to be issued at one time, it shall not be necessary to deliver an Officers’ Certificate and Opinion of Counsel at the time of issuance of each such Security, but such Officers’ Certificate and Opinion of Counsel shall be delivered at or before the time of issuance of the first Security of the series to be issued.

The Trustee shall not be required to authenticate such Securities if the issuance of such Securities pursuant to this Indenture would affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner not reasonably acceptable to the Trustee.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. Unless limited by the terms of such appointment, any such authenticating agent may authenticate Securities whenever the Trustee may do so.

Except as set forth in Section 2.16 or as may be provided pursuant to Section 2.01, when Securities of any series are presented to the Registrar with the request to register the transfer of those Securities or to exchange those Securities for an equal principal amount of Securities of the same series of like tenor and of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements and the requirements of this Indenture for those transactions are met; provided, however , that the Securities presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instruction of transfer in form reasonably satisfactory to the Registrar duly executed by the Holder thereof or by his attorney, duly authorized in writing, on which instruction the Registrar can rely.

To permit registrations of transfers and exchanges, the Company shall execute Securities (and, if applicable, each Guarantor with respect to such series shall execute the Notation of Guarantee for such series) and the Trustee shall authenticate such Securities at the Registrar’s written request and submission of the Securities (other than Global Securities). No service charge shall be made to a Holder for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than such transfer tax or similar governmental charge payable on exchanges pursuant to Section 2.13, Section 5.07 or Section 9.05). The Trustee shall authenticate Securities in accordance with the provisions of Section 2.04. Notwithstanding any other provisions of this Indenture to the contrary, the Company shall not be required to register the transfer or exchange of (a) any Security selected for redemption in whole or in part pursuant to Article V, except the unredeemed portion of any Security being redeemed in part or (b) any Security during the period beginning 15 Business Days before the mailing of notice of any offer to repurchase Securities of the series required pursuant to the terms thereof or of redemption of Securities of a series to be redeemed and ending at the close of business on the date of mailing.

Section 2.09 Mutilated, Destroyed, Lost or Wrongfully Taken Securities . If a mutilated Security is surrendered to the Registrar 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 authenticate a replacement Security with respect to such series if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Company or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or 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. Such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar

from any loss which any of them may suffer if a Security is replaced, and, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and, upon 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 wrongfully taken Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

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

Upon the issuance of any new Security under this Section 2.09, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in connection therewith.

Every new Security issued pursuant to this Section 2.09 in lieu of any mutilated, destroyed, lost or wrongfully taken Security shall constitute an original additional contractual obligation of the Company, any Guarantor (if applicable) and any other obligor upon the Securities of such series, whether or not the mutilated, destroyed, lost or wrongfully taken 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 of such series duly issued hereunder.

The provisions of this Section 2.09 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 wrongfully taken Securities.

Section 2.10 Outstanding Securities . Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those paid pursuant to Section 2.09 and those described in this Section 2.10 as not outstanding. A Security ceases to be outstanding in the event the Company or a Subsidiary of the Company holds the Security, provided , however , that (i) for purposes of determining which Securities are outstanding for consent or voting purposes hereunder, the provisions of Section 12.06 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 Trust 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 12.09, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Redemption Date, repurchase date or maturity date money sufficient to pay all amounts and Additional Amounts, if any, payable on that date with respect to the Securities (or portions thereof) to be redeemed, repurchased or maturing, as the case may be, and the 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 2.11 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 registration of transfer, exchange or payment. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and dispose of such Securities in accordance with its internal policies (subject to the record retention requirements of the Exchange Act), and certification of their cancellation shall be delivered to the Company promptly upon receipt by the Trustee of a Company Request. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

Section 2.12 Payment of Interest; Defaulted Interest . Unless otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, interest and Additional Amounts, if any, on any Security of such series 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 regular record date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 2.08.

Unless otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, any interest and Additional Amounts, if any, on any Security of such series 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 provided for in the Securities therefor (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 (a) or (b) below:

(a) 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 or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, 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 and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. 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 in Section 12.02, not less than 10 days prior to such Special Record Date. 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 (b).

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

Subject to the foregoing provisions of this Section 2.12, each Security delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest and Additional Amounts, if any, each as accrued and unpaid, and to accrue, which were carried by such other Security.

Section 2.13 Temporary Securities . Until definitive Securities of any series are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities of such series. Temporary Securities shall be substantially in the form of definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

Section 2.14 Persons Deemed Owners . The Company, any Guarantors, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered as the owner of that Security for the purpose of receiving payments of principal of, premium (if any) or interest on, or any Additional Amounts with respect to, that Security and for all other purposes. None of the Company, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary.

Section 2.15 Computation of Interest . Except as otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 2.16 Global Securities; Book-Entry Provisions . If Securities of a series are issuable in global form as a Global Security, as contemplated by Section 2.01, then, notwithstanding clause (11) of Section 2.01 and the provisions of Section 2.02, any such Global Security shall represent those of the outstanding Securities of that series as shall be specified therein and may provide that it shall represent the aggregate amount of outstanding Securities of that series from time to time endorsed thereon and that the aggregate amount of outstanding Securities of that series represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, transfers or redemptions. Any endorsement of a Global Security to reflect the amount, or any increase or decrease in the amount, of outstanding Securities of that series represented thereby shall be made by the Trustee (i) in such manner and upon instructions given by such Person or Persons as shall be specified in that Security or in a Company Order to be delivered to the Trustee pursuant to Section 2.04 or (ii) otherwise in accordance with written instructions or such other written form of instructions as is customary for the Depositary for that Security, from that Depositary or its nominee on behalf of any Person having a beneficial interest in that Global Security. Subject to the provisions of Section 2.04 and, if applicable, Section 2.13, the Trustee shall deliver and redeliver any Security in permanent global form in the manner and upon instructions given by the Person or Persons specified in that Security or in the applicable Company Order. With respect to the Securities of any series that are represented by a Global Security, the Company and any Guarantors authorize the execution and delivery by the Trustee of a letter of representations or other similar agreement or instrument in the form customarily provided for by the Depositary appointed with respect to that Global Security. Any Global Security may be deposited with the Depositary or its nominee, or may remain in the custody of the Trustee or the Security Custodian therefor pursuant to a FAST Balance Certificate Agreement or similar agreement between the Trustee and the Depositary. If a Company Order has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement

or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 12.05 and need not be accompanied by an Opinion of Counsel.

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 the Trustee or the Security Custodian as its custodian, or under that Global Security, and the Depositary may be treated by the Company, any Guarantor, the Trustee or the Security Custodian and any agent of the Company, any Guarantor, the Trustee or the Security Custodian as the absolute owner of that Global Security for all purposes whatsoever. Notwithstanding the foregoing, (i) the registered holder of a Global Security of any series may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder of Securities of that series is entitled to take under this Indenture or the Securities of that series and (ii) nothing herein shall prevent the Company, any Guarantor, the Trustee or the Security Custodian or any agent of the Company, any Guarantor, the Trustee, or the Security Custodian from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a beneficial owner of any Security.

Notwithstanding Section 2.08, and except as otherwise provided pursuant to Section 2.01, transfers of a Global Security shall be limited to transfers of that Global Security in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Security may be transferred in accordance with the rules and procedures of the Depositary. Securities of any series shall be transferred to all beneficial owners of a Global Security of that series in exchange for their beneficial interests in that Global Security if, and only if, either (1) the Depositary notifies the Company 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 either case, a successor depositary is not appointed by the Company within 90 days of such notice, (2) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of definitive Securities or (3) a Default or Event of Default has occurred and is continuing with respect to the Securities.

In connection with any transfer of a portion of the beneficial interests in a Global Security to beneficial owners pursuant to this Section 2.16, the Registrar shall reflect on its books and records the date and a decrease in the principal amount of the 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, if applicable, each Guarantor with respect to such series shall execute the Notation of Guarantee relating to such Global Security, if any, and the Trustee on receipt of a Company Order for the authentication and delivery of Securities shall authenticate and deliver, one or more Securities of the same series of like tenor and amount.

In connection with the transfer of all the beneficial interests in a Global Security of any series to beneficial owners pursuant to this Section 2.16, the Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in the Global Security, an equal aggregate principal amount of Securities of that series of authorized denominations.

None of the Company, any Guarantor or the Trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, Securities by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to those Securities, or for any other actions taken or not taken by the Depositary. None of the Company, any Guarantor or the

Trustee shall be liable for any delay by the related Global Security Holder or the Depositary in identifying the beneficial owners, and each such Person may conclusively rely on, and shall be protected in relying on, instructions from that Global Security Holder or the Depositary for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Securities to be issued).

The provisions of the last sentence of the third paragraph of Section 2.04 shall apply to any Global Security if that Global Security was never issued and sold by the Company and the Company or a Guarantor delivers to the Trustee the Global Security together with written instructions (which need not comply with Section 12.05 and need not be accompanied by an Opinion of Counsel) with regard to the cancellation or reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of the third paragraph of Section 2.04.

Notwithstanding the provisions of Section 2.03 and Section 2.12, unless otherwise specified as contemplated by Section 2.01 with respect to Securities of any series, payment of principal of and premium (if any) and interest on and any Additional Amounts with respect to any Global Security shall be made to the Person or Persons specified therein.

Section 2.17 CUSIP Numbers, Etc . The Company in issuing the Securities of any series may use CUSIP, ISIN and Common Code numbers (if then generally in use) and, if so, the Trustee shall use CUSIP, ISIN and Common Code numbers in notices of redemption as a convenience to Holders of Securities of such series; provided , however , that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities of such series or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities of such series, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP, ISIN and Common Code numbers.

Section 2.18 Original Issue Discount and Foreign-Currency Denominated Securities . In determining whether the Holders of the required principal amount of outstanding Securities have concurred in any direction, amendment, supplement, waiver or consent, unless otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, (a) the principal amount of an Original Issue Discount Security of such series shall be the principal amount thereof that would be due and payable as of the date of that determination upon acceleration of the Maturity thereof pursuant to Section 6.02, and (b) the principal amount of a Security of such series denominated in a foreign currency shall be the Dollar equivalent, as determined by the Company by reference to the noon buying rate in The City of New York for cable transfers for that currency, as that rate is certified for customs purposes by the Federal Reserve Bank of New York (the “Exchange Rate” ) on the date of original issuance of that Security, of the principal amount (or, in the case of an Original Issue Discount Security, the Dollar equivalent, as determined by the Company by reference to the Exchange Rate on the date of original issuance of that Security, of the amount determined as provided in (a) above), of that Security.

The principal corporate trust office of the Trustee at the address of the Trustee specified in Section 12.02 hereof (the “Corporate Trust Office” ) shall be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company will give prompt written notice to the Trustee of any change in the location of any such office or agency.

Section 6.02 Acceleration . Except as otherwise provided as contemplated by Section 2.01 with respect to the Securities of such series, if any Event of Default with respect to any Securities of such series at the time outstanding (other than those of the type described in clause (7) of Section 6.01) occurs and is continuing, the Trustee may, and at the direction of the Holders of at least 25% in aggregate principal amount of outstanding Securities of such series shall, declare the principal of all the Securities of that series, together with all accrued and unpaid interest and Additional Amounts, if any, and premium, if any, to be due and payable immediately by notice in writing to the Company and the Trustee specifying the respective Event of Default and that such notice is a notice of acceleration, and the same shall become immediately due and payable.

Except as otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, in the case of an Event of Default with respect to such series specified in clause (7) of Section 6.01 hereof, all outstanding Securities of such series shall become due and payable immediately without further action or notice by the Trustee or the Holders. Holders may not enforce this Indenture or the Securities except as provided in this Indenture.

Except as otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, at any time after a declaration of acceleration with respect to the Securities of such series, the Holders of a majority in principal amount of the Securities of that series then outstanding (by written notice to the Trustee) may, on behalf of the Holders of all the Securities of that series, rescind and cancel such declaration and its consequences if:

(1) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction;

(2) all existing Defaults and Events of Default with respect to Securities of that series have been cured or waived except nonpayment of principal of or interest on the Securities of that series that has become due solely by reason of such declaration of acceleration;

(3) to the extent the payment of such interest is lawful, interest (at the same rate specified in the Securities of such series) on overdue installments of interest and Additional Amounts, if any, and overdue payments of principal which has become due otherwise than by such declaration of acceleration has been paid;

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

(5) in the event of the cure or waiver of an Event of Default of the type described in (7) of Section 6.01, the Trustee has received an Officers’ Certificate and Opinion of Counsel that such Event of Default has been cured or waived.

Section 6.03 Other Remedies . If an Event of Default with respect to any series occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of (or premium, if any) or interest or Additional Amounts, if any, on the Securities of such series or to enforce the performance of any provision of the Securities of such series or this Indenture with respect to such series.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative. Every right and remedy given by this Article or by law to the Trustee or any Holder may be exercised from time to time, and as often as deemed expedient, by the Trustee or the Holders, as the case may be.

Section 6.04 Waiver of Past Defaults . Except as otherwise provided as contemplated by Section 2.01 with respect to the Securities of any series, the Holders of a majority in principal amount of the then outstanding Securities of such series by written notice to the Trustee may, on behalf of the Holders of all the Securities of such series, (a) waive, by their consent (including, without limitation consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities of such series), an existing Default or Event of Default, with respect to such series and its consequences or compliance with any provisions except (i) a Default or Event of Default in the payment of the principal of, or premium, if any, or interest or Additional Amounts, if any, on a Security of such series or (ii) a Default or Event of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected and (b) rescind any such acceleration with respect to the Securities of such series and its consequences if rescission would not conflict with any judgment or decree of a court of competent jurisdiction. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

Section 6.05 Control by Majority . With respect to Securities of any series, the Holders of a majority in principal amount of the outstanding Securities of such series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01 and Section 7.02, that the Trustee determines is unduly prejudicial to the rights of the other Holders or would involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

Section 6.06 Limitation on Suits . Subject to Section 6.07, a Holder of a Security of any series may not pursue any remedy with respect to this Indenture or the Securities of such series or any related Securities Guarantees unless:

(1) such Holder has previously given to the Trustee written notice stating that an Event of Default is continuing with respect to such series;

(2) Holders of at least 25% in aggregate principal amount of the outstanding Securities of such series have requested in writing that the Trustee pursue the remedy;

(3) such Holders have offered to the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

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

(5) the Holders of a majority in principal amount of the outstanding Securities of such series have not given the Trustee a direction that is inconsistent with such request within such 60-day period.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

Section 6.07 Rights of Holders to Receive Payment . Notwithstanding any other provision of this Indenture (including, without limitation, Section 6.06), the right of any Holder to receive payment of principal of, premium (if any) or interest or Additional Amounts, if any, when due on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee . If an Event of Default specified in clauses (1) or (2) of Section 6.01 occurs and is continuing with respect to Securities of any series, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) with respect to such series and the amounts provided for in Section 7.07.

Section 6.09 Trustee May File Proofs of Claim . The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its Subsidiaries or its or their respective creditors or properties and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities . If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money or property in the following order:

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

SECOND : to Holders for amounts due and unpaid on the Securities in respect of which or for the benefit of which such money has been collected, for principal, premium, if any, and interest and Additional Amounts, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal, premium, if any, and interest and Additional Amounts, if any, respectively; and

THIRD : to the Company or any Guarantors or to such other party as a court of competent jurisdiction may direct.

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

Section 6.11 Undertaking for Costs . In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken, suffered 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 the Company, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in outstanding principal amount of the Securities of any series.

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, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

Section 7.05 Notice of Defaults . If a Default or Event of Default with respect to the Securities of any series occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee shall mail to each Holder of a Security of such series notice of the Default or Event of Default within the later of 30 days after obtaining such knowledge and 90 days after it occurs, unless the Default was already cured or waived. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest or Additional Amounts, if any, on any Security of any series, the Trustee may withhold the notice if it in good faith determines that withholding the notice is in the interests of Holders of such series.

Section 7.06 Reports by Trustee to Holders . Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture and for so long as the Securities of any series remain outstanding, the Trustee shall mail to each Holder of Securities of such series a brief report dated as of such reporting date that complies with TIA § 313(a). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports required by TIA § 313(c).

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

Section 7.07 Compensation and Indemnity . The Company shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the Company and the Trustee shall from time to time agree in writing. 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 promptly upon request for all reasonable 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 Holders, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee against any and all losses, liabilities, damages, claims, penalties, fines or expenses (including reasonable attorneys’ and agents’ fees and expenses) (for purposes of this Section 7.07, “losses” ) incurred by it in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 7.07) and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise), except to the extent such losses may be attributable to its negligence or willful misconduct as determined by a court of competent jurisdiction. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall provide reasonable cooperation at the Company’s expense in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel provided that the Company shall not be required to pay such fees and expenses if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company and the Trustee in connection with such defense. The Company shall not be under any obligation to pay for any written settlement without its consent, which consent shall not be unreasonably delayed, conditioned or withheld. The Company need not reimburse any expense incurred by the Trustee through the Trustee’s own willful misconduct, gross negligence or bad faith.

To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of, interest and Additional Amounts, if any, on particular Securities.

The Company’s payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture, the resignation or removal of the Trustee and payment in full of the Securities. When the Trustee incurs expenses after the occurrence of a Default specified in clause (7) of Section 6.01 with respect to the Company, the expenses are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.08 Replacement of Trustee . No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee. The Trustee may resign at any time with respect to the Securities of one or more series by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Securities of any series may remove the Trustee with respect to the Securities of such series by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

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

(2) the Trustee is adjudged bankrupt or insolvent;

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

(4) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Company or by the Holders of a majority in principal amount of the then outstanding Securities of any series and such Holders of such series do not reasonably promptly appoint a successor Trustee, 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 promptly appoint a successor Trustee with respect to such series.

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

If the Trustee with respect to the Securities of a series 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 of such series 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 with respect to such series.

In case of the appointment of a successor Trustee with respect to all Securities, each such successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee, to the Company and to any Guarantors. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee, without any further act, deed or conveyance, shall have all the rights, power and duties of the retiring Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders.

The Company may, at its option and at any time, elect to have either Section 8.02 or Section 8.03 hereof be applied to all outstanding Securities of any series so subject to defeasance or covenant defeasance. Any such election shall be evidenced by a Board Resolution of the Company or in another manner specified as contemplated by Section 2.01 for such Securities.

Section 8.02 Legal Defeasance and Discharge . Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02 with respect to Securities of any series, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its Obligations with respect to all outstanding Securities of such series on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance” ) and each Guarantor, if applicable, shall be released and relieved from all of its Obligations under its Securities Guarantee with respect to such series. 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 with respect to such series, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) through (e) below, and to have satisfied all its other obligations under the Securities with respect to such series 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: (a) the rights of Holders of outstanding Securities with respect to such series to receive, solely from the trust fund described in Section 8.04 and Section 8.05 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest and Additional Amounts, if any, on such Securities when such payments are due, (b) the Company’s obligations with respect to such Securities under Article II and Section 3.01 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and any Guarantors’ obligations in connection therewith, (d) the optional redemption provisions, if any, with respect to such Securities, and (e) this Article VIII. If the Company exercises under Section 8.01 hereof the option applicable to this Section 8.02, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, payment of the Securities with respect to such series may not be accelerated because of an Event of Default. Subject to compliance with this Article VIII, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance . Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 with respect to Securities of any series, the Company shall, with respect to such series of Securities, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Section 3.02, Section 3.04, Section 4.01, and Article X, and any other covenants specified pursuant to Section 2.01 with respect to the outstanding Securities of such series, on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance” ) and each Guarantor, if applicable, shall be released from all of its obligations under its Securities Guarantee with respect to such series of Securities, and the Securities of such series shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders of such series (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 of such series, the Company and any Guarantors 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 a Default or 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. If the Company exercises under Section 8.01 hereof the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, payment of the Securities of such series may not be accelerated because of an Event of Default specified in clauses (3), (4) (with respect to Section 3.04) and (6) of such Section 6.01.

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

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of any other series.

After an amendment under this Section becomes effective, the Company shall mail to Holders of each Security affected thereby a notice briefly describing such amendment.

A consent to an amendment or a waiver by a Holder of a Security shall be in writing and bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective.

Section 9.05 Notation on or Exchange of Securities . If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder.

Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

Section 9.06 Trustee To Sign Amendments . The Trustee shall sign any amendment authorized pursuant to this Article IX if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall receive indemnity satisfactory to it and shall receive, and (subject to Section 7.01 and Section 7.02) shall be fully protected in conclusively relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Indenture, that such amendment is the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, subject to customary exceptions, and that such amendment complies with the provisions hereof (including Section 9.03).

Article X.

Securities Guarantee

Section 10.01 Securities Guarantee . Securities of any series that are to be guaranteed by the Securities Guarantees of any Guarantors shall be guaranteed by such Guarantors as shall be established pursuant to Section 2.01 as Guarantors with respect to the Securities of such series; provided that, prior to the authentication and delivery upon original issuance of Securities of any series that are to be guaranteed by a Person, the Company, the Trustee and such Person shall have entered into a supplemental indenture pursuant to clause (3) of Section 9.01 hereof whereby such Person shall have executed a Securities Guarantee under this Indenture with respect to any series of Securities as to which such Person has been so established pursuant to Section 2.01 as a Guarantor thereof and shall have made each of the covenants and agreements of a Guarantor hereunder with respect to each such series.

Securities of any series that are to be guaranteed by the Securities Guarantees of any Guarantors shall be guaranteed in accordance with the terms of such Securities Guarantees as established pursuant to Section 2.01 with respect to such series of Securities and such Securities Guarantees thereof and (except as otherwise specified as contemplated by Section 2.01 for such series of Securities and such Securities Guarantees thereof) in accordance with this Article X. Notwithstanding any provision of this Article X to the contrary, the provisions of this Article X relating to any Guarantor shall (i) be applicable only to, and inure solely to the benefit of, the Securities of any series designated, pursuant to Section 2.01, as entitled to the benefits of the related Securities Guarantee of such Guarantor with respect to such series and (ii) so be applicable, and inure to the benefit of, the Securities of such series except to the extent otherwise provided as contemplated by Section 2.01 with respect to the Securities of such series.

Any Guarantor shall fully and unconditionally guarantee, as primary obligor and not merely as surety, jointly and severally with any other Guarantor, to each Holder of the Securities and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, interest and Additional Amounts, if any, on the Securities and all other monetary Obligations of the Company under this Indenture. Any Guarantor shall further agree (to the extent permitted by law) that the Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it will remain bound under this Article X notwithstanding any extension or renewal of any Obligation.

Any Guarantor shall waive presentation to, demand of payment from and protest to the Company of any of the Obligations and also shall waive notice of protest for nonpayment. Any Guarantor shall waive notice of any default under the Securities or the Obligations. The obligations of any Guarantor shall not be affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Indenture, the Securities or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement (other than any such waiver, amendment or modification that expressly modifies a Guarantor’s obligations); (d) the release of any collateral security held by any Holder or the Trustee for the Obligations of any of them; (e) the failure of any Holder to exercise any right or remedy against any other Guarantor; or (f) any change in the ownership of the Company.

Any Guarantor shall further agree that its Securities Guarantee constitutes a Guarantee of payment when due (and not a Guarantee of collection) and shall waive any right to require that any resort be had by any Holder to any Security held for payment of the Obligations.

Except as expressly set forth in Article VIII and Section 10.03, the obligations of each Guarantor shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor shall not be discharged or impaired or otherwise affected by the failure of the Trustee or any Holder to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof (other than any waiver or modification that expressly modifies a Guarantor’s obligations), by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of such Guarantor as a matter of law or equity.

Each Guarantor shall further agree that its Securities Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest or Additional Amounts, if any, on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law) and except as provided in Section 10.03.

Each Guarantor shall further agree that, as between such Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations Guaranteed may be accelerated as provided in this Indenture for the purposes of its Securities Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations Guaranteed and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purposes of the Securities Guarantee.

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

Section 10.02 Execution and Delivery of Securities Guarantees; Notations of Guarantees . The Securities Guarantee of any Guarantor with respect to Securities of any series as to which such Guarantor has been established as a Guarantor pursuant to Section 2.01 shall be fully evidenced by such Guarantor’s execution and delivery of a supplemental indenture hereto. Anything herein to the contrary

notwithstanding, there shall be no requirement that any Security having the benefit of a Securities Guarantee have endorsed thereon or attached thereto such Securities Guarantee or a notation of such Securities Guarantee. Solely with respect to Securities of any series that are entitled to the benefits of any Securities Guarantee of any Guarantor and as to which Notations of Guarantee are to be included on such Securities as designated pursuant to clause (9) of Section 2.01, to further evidence its Securities Guarantee set forth in Section 10.01 or otherwise established pursuant hereto with respect to Securities of such series, each of the Guarantors with respect to Securities of any series shall agree that a notation relating to such Securities Guarantee (the “Notation of Guarantee” ), substantially in the form attached hereto as Annex A, shall be endorsed on each Security of such series entitled to the benefits of such Securities Guarantee authenticated and delivered by the Trustee, which Notation of Guarantee shall be executed by either manual or facsimile signature (or other electronic means) of an Officer of such Guarantor. Each of the Guarantors with respect to Securities of any series shall agree that its Securities Guarantee set forth in Section 10.01 or otherwise established pursuant hereto with respect to Securities of such series shall remain in full force and effect notwithstanding any absence of Notations of Guarantees as to such series or any failure to endorse on any Security the Notation of Guarantee relating to such Securities Guarantee. If any Officer of any Guarantor with respect to Securities of any series, whose signature is on the Notation of Guarantee on any Security of such series, no longer holds that office at the time the Trustee authenticates any Security or at any time thereafter, the Securities Guarantee of such Security shall be valid nevertheless. The delivery of any Security of a series entitled to the benefits of a Securities Guarantee under this Article X or otherwise established pursuant hereto by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of such Securities Guarantee on behalf of each Guarantor.

Section 10.03 Limitation on Liability; Termination, Release and Discharge .

(a) The obligations of any Guarantor will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Securities Guarantee or pursuant to its contribution obligations under this Indenture, result in the obligations of such Guarantor under its Securities Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law.

(b) The Securities Guarantee of a Guarantor shall be automatically and unconditionally released and discharged, without the consent of the Holders, and no further action by the Company, any Guarantor or the Trustee shall be required for such release (unless the Company shall notify the Trustee that no release and discharge shall occur as a result thereof) upon:

(1) the sale or other disposition (including by way of consolidation or merger) of such Guarantor to a Person other than the Company or any Subsidiary of the Company in a transaction or series of transactions not prohibited by this Indenture;

(2) the sale or other disposition of all or substantially all of the assets of such Guarantor to a Person other than the Company or any Subsidiary of the Company in a transaction or series of transactions not prohibited by this Indenture;

(3) upon Legal Defeasance or Covenant Defeasance as provided in Article VIII or upon satisfaction and discharge of this Indenture as provided in Article XI; or

(4) the delivery of an Officers’ Certificate to the Trustee that such Guarantor does not guarantee the Company’s obligations under the Credit Agreement.

(c) Any Guarantor not released from its obligations under its Securities Guarantee shall remain liable for the full amount of principal of and interest on the Securities and for the other obligations of any Guarantor as provided in this Article X.

(d) At any time after the issuance of any series of Securities that is entitled to the benefits of any Securities Guarantee, including following the release of a Guarantor from its Securities Guarantee, the Company shall cause any of its Subsidiaries that is a guarantor under the Credit Agreement to promptly execute and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiary will become a Guarantor in respect of such series of Securities.

Section 10.04 Limitation of Guarantors’ Liability . Any Guarantor, and by its acceptance thereof each Holder, shall confirm that it is the intention of all such parties that the Guarantee by such Guarantor pursuant to its Securities Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law. To effectuate the foregoing intention, the Holders and each Guarantor shall irrevocably agree that the obligations of such Guarantor under its Securities Guarantee will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Securities Guarantee or pursuant to Section 10.05 hereof, result in the obligations of such Guarantor under its Securities Guarantee not constituting such a fraudulent conveyance or fraudulent transfer. This Section 10.04 is for the benefit of the creditors of each Guarantor.

Section 10.05 Contribution . In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree that in the event any payment or distribution is made by any Guarantor (a “Funding Guarantor” ) under its Securities Guarantee, such Funding Guarantor will be entitled to a contribution from each other Guarantor (if any) in a pro rata amount based on the Adjusted Net Assets of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s obligations with respect to the Securities or any other Guarantor’s obligations with respect to its Securities Guarantee.

Section 10.06 Guarantors May Consolidate, etc., on Certain Terms .

(a) Except as otherwise provided in Section 10.03 in connection with any release and discharge of a Guarantor, no Guarantor may consolidate or combine with or merge with or into (whether or not such Guarantor is the surviving person) or sell or convey all or substantially all of its assets to another Person whether or not affiliated with such Guarantor, unless the Person formed by or surviving any such consolidation, combination or merger or the transferee Person (in each case if other than a Guarantor or the Company) unconditionally assumes all the obligations of such Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee.

In case of any such consolidation, merger, combination, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of such Securities Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person shall become a Guarantor (and succeed to and be substituted for the predecessor to the extent of any release and discharge of such predecessor pursuant to Section 10.03).

(b) Notwithstanding clause (a) above, nothing contained in this Indenture or in any of the Securities shall prevent any consolidation, combination or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale or conveyance of all or substantially all of the assets of a Guarantor to the Company or another Guarantor.

Section 11.01 Satisfaction and Discharge . This Indenture will be discharged and will cease to be of further effect as to all Securities of any series issued hereunder (except as to surviving rights of registration of transfer or exchange of such Securities and as otherwise specified hereunder), when:

(1) either:

(a) all Securities of such series that have been authenticated, except lost, stolen or destroyed Securities that have been replaced or paid and Securities of such series for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

(b) all Securities of such series that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the mailing of a notice of redemption or otherwise and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of Securities of such series, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on such Securities not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest and Additional Amounts, if any, to the date of maturity or redemption;

(2) no Default or Event of Default with respect to such series has occurred and is continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(3) the Company or any Guarantor has paid or caused to be paid all sums payable by it hereunder with respect to such series and pursuant to Section 7.07;

(4) the Company has delivered irrevocable instructions to the Trustee hereunder to apply the deposited money toward the payment of such Securities at fixed maturity or the Redemption Date, as the case may be; and

(5) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, which state that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture with respect to such series have been satisfied.

Section 11.02 Application of Trust Money . All money deposited with the Trustee pursuant to Section 11.01 with respect to Securities of any series shall be held in trust and applied by it, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal and any premium and interest for whose payment such money has been deposited with the Trustee. All moneys deposited with the Trustee pursuant to Section 11.01 (and held by it or any Paying Agent) for the payment of Securities subsequently converted shall be returned to the Company upon Company Request, to the extent originally deposited by the Company. The Company may direct by a Company Order the investment of any money deposited with the Trustee pursuant to Section 11.01, without distinction between principal and income, in (1) United States Treasury Securities with a maturity of one year, or less or (2) a money market fund that invests solely in short term United States Treasury Securities, and from time to time the Company may direct the reinvestment of all or a portion of such money in other securities or funds meeting the criteria specified in preceding clauses (1) or (2) of this sentence.

In determining whether the Holders of the required principal amount of Securities of any series have concurred in any direction, waiver or consent, Securities owned by the Company or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Also, subject to the foregoing, only Securities outstanding at the time shall be considered in any such determination.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the sufficiency and adequacy of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I

DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.01. Definitions .

(a) All capitalized terms used herein and not otherwise defined below shall have the meanings ascribed thereto in the Indenture.

(b) The following are definitions used in this First Supplemental Indenture, and to the extent that a term is defined both herein and in the Indenture, the definition in this First Supplemental Indenture shall govern with respect to the Notes.

“ Attributable Debt ” with regard to a Sale and Leaseback Transaction with respect to any Principal Property means, at the time of determination, the present value of the total net amount of rent required to be paid under the lease during the remaining term thereof (including any period for which the lease has been extended), discounted at the rate of interest set forth or implicit in the terms of the lease (or, if not practicable to determine the rate, the weighted average interest rate per annum borne by the Notes then outstanding under the Indenture) compounded semi-annually. In the case of any lease that is terminable by the lessee upon the payment of a penalty, the net amount of rent will be the lesser of (x) the net amount determined assuming termination upon the first date the lease may be terminated (in which case the net amount will also include the amount of the penalty, but will not include any rent that would be required to be paid under the lease subsequent to the first date upon which it may be so terminated) or (y) the net amount determined assuming no such termination.

“ Capital Lease ” means a lease with respect to which the lessee is required concurrently to recognize the acquisition of an asset and the incurrence of a liability in accordance with generally accepted accounting principles in effect in the United States as of the date of the Indenture.

2

“ Change of Control ” means the occurrence of any one of the following:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) other than to the Company and/or one or more of its Subsidiaries;

(2) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company, measured by voting power rather than number of shares;

(3) the Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or the Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of Voting Stock of the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, at least a majority of the Voting Stock of the surviving Person immediately after giving effect to such transaction;

(4) the first day on which the majority of the members of the board of directors of the Company cease to be Continuing Directors; or

(5) the approval by the holders of the Voting Stock of the Company of any plan for the liquidation or dissolution of the Company.

“ Change of Control Triggering Event ” means the Notes cease to be rated Investment Grade by each of the Rating Agencies on any date during the period (the “ Trigger Period ”) commencing on the date of the Company’s first public announcement of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control or, if earlier, upon abandonment of the Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings downgrade). Unless at least two of the three Rating Agencies are providing a rating for the Notes at the commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated Investment Grade by each of the three Rating Agencies during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

3

“ Comparable Treasury Issue ” means the U.S. Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes to be redeemed.

“ Comparable Treasury Price ” means, with respect to any Redemption Date (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four Reference Treasury Dealer Quotations, the average of all of these quotations.

“ Consolidated Tangible Assets ” means, as of any date, total assets (excluding treasury stock, unamortized debt discount and expense, goodwill, trademarks, trade names, patents, deferred charges and other intangible assets) of the Company and its Subsidiaries on a consolidated basis, as determined in accordance with GAAP.
