The principal of and any interest on the Securities shall be payable at the office or agency of the Company designated in the form of Security for the series (each such place herein called the “Place of Payment”); provided, however, that payment of interest may be made at the option of the Company by check mailed to the address of the Person entitled thereto as such address shall appear in the register of Securities referred to in Section 2.03 hereof.

Each Security shall be in one of the forms approved from time to time by or pursuant to a Board Resolution or Officers’ Certificate, or established in one or more indentures supplemental hereto. Prior to the delivery of a Security to the Trustee for authentication in any form approved by or pursuant to a Board Resolution or Officers’ Certificate, the Company shall deliver to the Trustee the Board Resolution or Officers’ Certificate by or pursuant to which such form of Security has been approved, which Board Resolution or Officers’ Certificate shall have attached thereto a true and correct copy of the form of Security that has been approved by or pursuant thereto.

The Securities may have notations, legends, or endorsements required by law, stock exchange rule, or usage. Each Security shall be dated the date of its authentication.

Section 2.02 Execution and Authentication.

One or more Officers 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 Security is authenticated, the Security shall nevertheless be valid.

A Security shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee shall authenticate Securities for original issue upon receipt of a Company Order.

The Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or an Affiliate of the Company.

Section 2.03 Registrar and Paying Agent.

The Company shall maintain an office or agency where Securities of a particular series may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities of that series may be presented for payment (a “Paying Agent”). The Registrar for a particular series of Securities shall keep a register of the Securities of that series and of their registration of transfer and exchange. The Company may appoint one or more co-Registrars and one or more additional paying agents for each series of Securities. The term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent, Registrar, or co-Registrar without prior notice to any Securityholder. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture.

If the Company fails to maintain a Registrar or Paying Agent for any series of Securities, the Trustee shall act as such. The Company or any of its Affiliates may act as Paying Agent, Registrar, or co-Registrar.

The Company hereby appoints the Trustee the initial Registrar and Paying Agent for each series of Securities unless another Registrar or Paying Agent, as the case may be, is appointed prior to the time Securities of that series are first issued.

Section 2.04 Paying Agent to Hold Money in Trust.

Whenever the Company has one or more Paying Agents it will, prior to each due date of the principal of, or interest on, any Securities, deposit with a Paying Agent a sum sufficient to pay the principal or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent will hold in trust for the benefit of the Securityholders of the particular series for which it is acting, or the Trustee, all money held by the Paying Agent for the payment of principal or interest on the Securities of such series, and that such Paying Agent will notify the Trustee of any Default by the Company or any other obligor of the series of Securities in making any such payment and at any time during the continuance of any such Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. If the Company or an Affiliate acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Securityholders of the particular series for which it is acting all money held by it as Paying Agent. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon so doing, the Paying Agent (if other than the Company or an Affiliate of the Company) shall have no further liability for such money. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Paying Agent for the Securities.

Section 2.05 Securityholder 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 Securityholders, separately by series, and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders, separately by series, relating to such interest payment date or request, as the case may be.

Section 2.06 Transfer and Exchange.

Where Securities of a series are presented to the Registrar or a co-Registrar with a request to register a transfer or to exchange them for an equal principal amount of Securities of the same series of other authorized denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Company shall issue and the Trustee shall authenticate Securities at the Registrar’s request.

No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant to Sections 2.09, 2.13, 3.06 or 9.04).

The Company need not issue, and the Registrar or co-Registrar need not register the transfer or exchange of, (i) any Security of a particular series during a period beginning at the opening of business 15 days before the day of any selection of Securities of that series for redemption under Section 3.02 and ending at the close of business on the day of selection, or (ii) any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security of that series being redeemed in part.

Section 2.07 Replacement Securities.

If a mutilated Security is surrendered to 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 authenticate a replacement Security of same series if the Company’s and the Trustee’s requirements are met. The Trustee or the Company may require an indemnity bond to be furnished which is sufficient in the judgment of both to protect the Company, the Trustee, and any Agent from any loss which any of them may suffer if a Security is replaced. The Company or the Trustee may charge such Holder for its expenses in replacing a Security.

Every replacement Security is an obligation of the Company and shall be entitled to all the benefit of the Indenture equally and proportionately with any and all other Securities of the same series.

Section 2.08 Outstanding Securities.

The Securities of any series outstanding at any time are all the Securities of that series authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, and those described in this Section as not outstanding.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser.

If Securities are considered paid under Section 4.01, they cease to be outstanding and interest on them ceases to accrue.

Except as set forth in Section 2.09 hereof, a Security does not cease to be outstanding because the Company or an Affiliate holds the Security.

For each series of Original Issue Discount Securities, the principal amount of such Securities that shall be deemed to be outstanding and used to determine whether the necessary Holders have given any request, demand, authorization, direction, notice, consent, or waiver shall be the principal amount of such Securities that could be declared to be due and payable upon acceleration upon an Event of Default as of the date of such determination. When requested by the Trustee, the Company shall advise the Trustee of such amount, showing its computations in reasonable detail.

Section 2.09 Temporary Securities.

Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities upon a Company Order. 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.

Holders of temporary securities shall be entitled to all of the benefits of this Indenture.

Section 2.10 Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, or payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment, replacement, or cancellation and shall return such canceled Securities to the Company at the Company’s written request. The Company may not issue new Securities to replace Securities that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.11 Defaulted Interest.

If the Company fails to make a payment of interest on any series of Securities, the Company shall pay such defaulted interest plus (to the extent lawful) any interest payable on the defaulted interest, in any lawful manner. It may elect to pay such defaulted interest, plus any such interest payable on it, to the Persons who are Holders of such Securities on which the interest is due on a subsequent special record date. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each such Security and the date of the proposed payment. The Company shall fix or cause to be fixed any such record date and payment date for such payment, provided that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before any such record date, the Company shall mail to Securityholders affected thereby a notice that states the record date, payment date, and amount of such interest to be paid.

Section 2.12 Special Record Dates.

(a) The Company may, but shall not be obligated to, set a record date for the purpose of determining the identity of Holders entitled to consent to any supplement, amendment, or waiver permitted by this Indenture. If a record date is fixed, the Holders of Securities of that series outstanding on such record date, and no other Holders, shall be entitled to consent to such supplement, amendment, or waiver or revoke any consent previously given, whether or not such Holders remain Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the principal amount of Securities of that series required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period.

(b) The Company may, but shall not be obligated to, fix any day as a record date for the purpose of determining the Holders of any series of Securities entitled to join in the giving or making of any notice of Default, any declaration of acceleration, any request to institute proceedings, or any other similar direction. If a record date is fixed, the Holders of Securities of that series outstanding on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request, or direction, whether or not such Holders remain Holders after such record date; provided, however, that no such action shall be effective hereunder unless taken on or prior to the date 90 days after such record date.

Section 2.13 Global Securities.

(a) Terms of Securities. A Board Resolution, a supplemental indenture hereto, or an Officers’ Certificate shall establish whether the Securities of a series shall be issued in whole or in part in the form of one or more Global Securities and the Depositary for such Global Security or Securities.

(b) Transfer and Exchange. Notwithstanding any provisions to the contrary contained in Section 2.06 of this Indenture and in addition thereto, any Global Security shall be exchangeable pursuant to Section 2.06 of this Indenture for securities registered in the names of Holders other than the Depositary for such Security or its nominee only if (i) such Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, the Company fails to appoint a successor Depositary within 90 days of such event; or (ii) the Company executes and delivers to the Trustee an Officers’ Certificate to the effect that such Global Security shall be so exchangeable. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as the Depositary shall direct in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms.

Except as provided in this paragraph (b) of this Section, a Global Security may not be transferred except as a whole by the Depositary with respect to such Global Security to a nominee of such Depositary, by a nominee of such Depositary to such Depositary or another nominee of such Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such a successor Depositary.

“Unless this certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), New York, New York, to the issuer or its agent for registration of transfer, exchange, or payment and any certificate issued is registered in the name of Cede & Co. or such other name as may be requested by an authorized representative of DTC (and any payment is made to Cede & Co. or such other entity

as may be requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co. has an interest herein.

Transfer of this Global Security shall be limited to transfers in whole, but not in part, to nominees of DTC or to a successor thereof or such successor’s nominee and limited to transfers made in accordance with the restrictions set forth in the Indenture referred to herein.”

(d) Acts of Holders. The Depositary, as a Holder, may appoint agents and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver, or other action which a Holder is entitled to give or take under this Indenture.

(e) Payments. Notwithstanding the other provisions of this Indenture, unless otherwise specified as contemplated by Section 2.01 hereof, payment of the principal of and interest, if any, on any Global Security shall be made to the Person specified therein.

(f) Consents, Declaration, and Directions. Except as provided in paragraph (e) of this Section, the Company, the Trustee, and any Agent shall treat a Person as the Holder of such principal amount of outstanding Securities of such series represented by a Global Security as shall be specified in a written statement of the Depositary with respect to such Global Security, for purposes of obtaining any consents, declarations, or directions required to be given by the Holders pursuant to this Indenture.

Section 2.14 CUSIP Numbers.

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

ARTICLE 3

REDEMPTION

Section 3.01 Notices to Trustee.

If the Company elects to redeem Securities of any series pursuant to any optional redemption provisions thereof, it shall furnish to the Trustee at least 30 days, but not more than 60 days before a redemption date, an Officer’s Certificate which shall specify (i) the provisions of such Security or this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of Securities of that series to be redeemed, and (iv) the redemption price.

If the Company elects to reduce the principal amount of Securities of any series to be redeemed pursuant to mandatory redemption provisions thereof, it shall notify the Trustee of the amount of, and the basis for, any such reduction. If the Company elects to credit against any such mandatory redemption Securities it has not previously delivered to the Trustee for cancellation, it shall deliver such Securities with such notice.

Section 3.02 Selection of Securities to Be Redeemed.

If less than all the Securities of any series are to be redeemed, or purchased in an offer to purchase at any time, the Trustee shall select the Securities of that series to be redeemed or purchased as follows: (1) if the Securities of such series are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Securities of that series are listed, or (2) if the Securities of that series are not listed on a national securities exchange, on a pro rata basis, by lot or by such other method as the Trustee deems fair and appropriate. In the event of a partial redemption or purchase by lot, the particular Securities to be redeemed or purchased will be selected not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from Securities of that series outstanding and not previously called for redemption.

The Trustee shall notify the Company promptly in writing of the Securities or portions of Securities to be called for redemption or purchase and, in the case of any Securities selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Except as otherwise provided as to any particular series of Securities, Securities and portions thereof that the Trustee selects shall be in amounts equal to the minimum authorized denomination for Securities of the series to be redeemed or purchased or any integral multiple thereof, except that if all of the Securities of the series are to be redeemed or purchased, the entire outstanding amount of the Securities of the series held by such Holder, even if not equal to the minimum authorized denomination for the Securities of that series, shall be redeemed or purchased. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

Section 3.03 Notice of Redemption.

Except as otherwise provided as to any particular series of Securities, at least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption to each Holder whose Securities are to be redeemed.

The notice shall identify the Securities of the series to be redeemed and shall state:

(1) the redemption date;

(2) the redemption price fixed in accordance with the terms of the Securities of the series to be redeemed, plus accrued interest, if any, to the date fixed for redemption (the “redemption price”);

(3) 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, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Securities;

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

(5) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Company defaults in payment of the redemption price, interest on Securities called for redemption ceases to accrue on and after the redemption date;

(7) the CUSIP number, if any, of the Securities to be redeemed;

(8) the paragraph of the Securities and/or the section of the Indenture pursuant to which the Securities called for redemption are being redeemed; and

(9) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Securities.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. The notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice of the Holder of any Security shall not affect the validity of the proceeding for the redemption of any other Security.

Section 3.04 Effect of Notice of Redemption.

Except if the giving of a notice of redemption would violate the terms of the Company’s credit agreement, and subject to the subordination provisions of any series of Securities, once notice of redemption is mailed in accordance with Section 3.03 hereof, Securities called for redemption become due and payable on the redemption date for the redemption price. Upon surrender to the Paying Agent, such Securities will be paid at the Redemption Price.

Section 3.05 Deposit of Redemption Price.

On or before 10:00 a.m., New York City time, on the redemption or purchase date, the Company shall deposit with the Trustee or Paying Agent (or, if the Company or any Affiliate is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption or purchase price of all Securities called for redemption on that date other than Securities that have previously been delivered by the Company to the Trustee for cancellation. The Paying Agent shall return to the Company any money not required for that purpose.

If the Company complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest shall cease to accrue on the Securities (or the portions thereof) called for redemption or purchase. If a Security is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Securities were registered at the close of business on such record date. If any Securities called for redemption or purchase shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in accordance with the terms of the Securities of the series to be redeemed.

Section 3.06 Securities Redeemed or Purchased in Part.

Upon surrender of a Security that is redeemed or purchased in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Security of same series equal in principal amount to the unredeemed or unpurchased portion of the Security surrendered.

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices, and demands may be made or served at the Corporate Trust Office of the Trustee.

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; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03.

Section 4.03 Reports.

The Company also shall comply with the other provisions of TIA Section 314(a).

Delivery of such reports, information, and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 4.04 Compliance Certificate.

(a) The Company or any Guarantors shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company, an Officers’ Certificate stating that a review of the activities of the Company and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers (one of whom shall be the principal executive officer, principal financial officer, or principal accounting officer of the Company) with a view to determining whether the Company has kept, observed, performed, and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his or her knowledge the Company has kept, observed, performed, and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions, and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Company is taking or proposes to take with respect thereto) and that to the best of his or her knowledge no event has occurred and remains in existence by reason of which payments on account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Company is taking or proposes to take with respect thereto.

The Company shall pay prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of any Securities.

Section 4.06 Stay, Extension, and Usury Laws.

The Company and any Guarantors covenant (to the extent that it may lawfully do so) that they shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension, or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each Guarantor (to the extent that they may lawfully do so) hereby expressly waive all benefits or advantages of any such law, and covenant that they shall not, by resort to any such law, hinder, delay, or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.07 Calculation of Original Issue Discount.

If, as of the end of any fiscal year of the Company, the Company has any outstanding Original Issue Discount Securities under the Indenture, the Company shall file with the Trustee promptly following the end of such fiscal year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on such Original Issue Discount Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be required under the Internal Revenue Code of 1986, as amended from time to time.

SUCCESSORS

Section 5.01 When Company May Merge, Etc.

In addition to provisions applicable to a particular series of Securities, the Company shall not directly or indirectly: (i) consolidate or merge with or into another Person (whether or not the Company is the surviving Person) or (ii) sell, assign, transfer, lease, convey, or otherwise dispose of all or substantially all of the properties or assets of the Company and its Subsidiaries in one or more related transactions to any Person unless:

(2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, lease, conveyance, or other disposition shall have been made assumes (by supplemental indenture reasonably satisfactory to the Trustee) all the obligations of the Company under the Securities and this Indenture; and

(3) immediately after the transaction no Default or Event of Default exists.

ARTICLE 6

DEFAULTS AND REMEDIES

Section 6.01 Events of Default.

An “Event of Default” occurs with respect to Securities of any particular series if, unless as otherwise provided in the establishing Board Resolution, Officers’ Certificate, or supplemental indenture hereto:

(1) the Company defaults in the payment of interest on any Security of that series when the same becomes due and payable and the Default continues for a period of 30 days;

(2) the Company defaults in the payment, when due, of the principal of, or premium, if any, on any Security of that series when the same becomes due and payable at Maturity, upon redemption (including in connection with any offer to purchase under the terms of such Securities), or otherwise;

(3) an Event of Default, as defined in the Securities of that series, occurs and is continuing, or the Company fails to comply with any of its other agreements in the Securities of that series or in this Indenture with respect to that series and the Default continues for the period and after the notice specified below;

(4) the Company pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary case;

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

(D) makes a general assignment for the benefit of its creditors; or

(E) admits in writing its inability generally to pay its debts as the same become due.

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

(A) is for relief against the Company in an involuntary case;

(B) appoints a Custodian of the Company or for all or substantially all of its property; or

(6) any other Event of Default provided with respect to Securities of that series which is specified in a Board Resolution, Officers’ Certificate, or supplemental indenture establishing that series of Securities.

The term “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, or similar official under any Bankruptcy Law.

A Default under clause (3) above is not an Event of Default with respect to a particular series of Securities until the Trustee or the Holders of at least 50% in principal amount of the then outstanding Securities of that series notify the Company of the Default and the Company does not cure the Default within 60 days after receipt of the notice. The notice must specify the Default, demand that it be remedied, and state that the notice is a “Notice of Default.” Such notice shall be given by the Trustee if so requested in writing by the Holders of 50% of the principal amount of the then outstanding Securities of that series.

Section 6.02 Acceleration.

If an Event of Default with respect to Securities of any series (other than an Event of Default specified in clauses (4) and (5) of Section 6.01) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 50% in principal amount of the then outstanding Securities of that series by notice to the Company and the Trustee, may, subject to any prior notice requirements set forth in any supplemental indenture, declare the unpaid principal (or, in the case of Original Issue Discount Securities, such lesser amount as may be provided for in such Securities) of and any accrued interest on all the Securities of that series to be due and payable on the Securities of that series. Upon such declaration the principal (or such lesser amount) and interest shall be due and payable immediately. If an Event of Default specified in clause (4) or (5) of Section 6.01 occurs, all of such amount shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in principal amount of the then outstanding Securities of that series by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect to that series have been cured or waived except nonpayment of principal (or such lesser amount) or interest that has become due solely because of the acceleration.

Section 6.03 Other Remedies.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal or interest on the Securities of that series or to enforce the performance of any provision of the Securities of that series or this Indenture.

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 an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

Subject to Section 6.02, the Holders of not less than a majority in aggregate principal amount of the then outstanding Securities of any series, by notice to the Trustee, may on behalf of the Holders of the Securities of that series, waive an existing Default or Event of Default with respect to that series and its consequences except a continuing Default or Event of Default in the payment of the principal (including any mandatory sinking fund or like payment) of, premium, if any, or interest on any Security of that series (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the outstanding Securities of any series may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration and its consequences, including

any related payment default that resulted from any such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

The Holders of a majority in principal amount of the then outstanding Securities of any series may direct the time, method, and place of conducting any proceeding for exercising any remedy with respect to that series available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders of Securities of that series, or that may involve the Trustee in personal liability. The Trustee may take any other action which it deems proper that is not inconsistent with any such direction. Notwithstanding any provision to the contrary in this Indenture, the Trustee shall not be obligated to take any action with respect to the provisions of Section 6.02 unless directed to do so pursuant to this Section 6.05.

Section 6.06 Limitation on Suits.

A Holder of Securities of any series may not pursue a 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 with respect to that series;

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

(3) such Holder or Holders offer, and, if requested, 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 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

(5) during such 60-day period the Holders of a majority in principal amount of the then outstanding Securities of that series do not give the Trustee a direction inconsistent with the request.

No Holder of any series of Securities may use this Indenture to prejudice the rights of another Holder of Securities of that series or to obtain a preference or priority over another Holder of Securities of that series.

Section 6.07 Rights of Holders to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal, premium, if any, and interest on the Security, on or after the respective due dates expressed in the Security (including in connection with any offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not, except as provided in the subordination provisions, if any, applicable to such Security, be impaired or affected without the consent of the Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) hereof 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 of principal (or such portion of the principal as may be specified as due upon acceleration at that time in the terms of that series of Securities), premium, if any, and interest, remaining unpaid on the Securities of that series then outstanding, together with (to the extent lawful) interest on overdue principal and interest, and such further amount as shall be sufficient to cover the costs and, to the extent lawful, expenses of collection, including the reasonable compensation, expenses, disbursements, and advances of the Trustee, its agents, and counsel, and any other amounts due the Trustee under Section 7.07 hereof.

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 reasonable compensation, expenses, disbursements, and advances of the Trustee, its agents, and counsel, and any other amounts due to the Trustee under Section 7.07 hereof) and the Securityholders allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors, or its property and shall be entitled to and empowered to collect, receive, and distribute any money or other property payable or deliverable on any such claims, 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 reasonable compensation, expenses, disbursements, and advances of the Trustee, its agent, and counsel, and any other amounts due the Trustee under Section 7.07 hereof. Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Securityholder 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 Securityholder in any such proceeding.

Section 6.10 Priorities.

FIRST: to the Trustee, its agents, and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense, and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

SECOND: in accordance with the subordination provisions, if any, of the Securities of such series;

ARTICLE 7

TRUSTEE

Section 7.01 Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

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

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture or the TIA and the Trustee need perform only those duties that are specifically set forth in this Indenture or the TIA and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any certificates or opinions which by any provision hereof are specifically

required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

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

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power, including without limitation, the provisions of Section 6.05 hereof, unless it receives security and indemnity satisfactory to it against any loss, liability or expense.

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Absent written instruction from the Company, the Trustee shall not be required to invest any such money. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

Section 7.02 Rights of Trustee.

Subject to TIA Section 315(a) through (d):

(a) The Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness, or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit.

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

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers under the Indenture, unless the Trustee’s conduct constitutes negligence.

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction, or notice from the Company shall be sufficient if signed by an Officer of the Company.

(f) The Trustee may consult with counsel of its selection and may rely upon the advice of such counsel or any Opinion of Counsel.

(g) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer of the Trustee has actual knowledge thereof or unless written notice of any event that is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities generally or the Securities of a particular series, as the case may be, and this Indenture.

(h) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as duties.

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to TIA Sections 310(b) and 311.

Section 7.04 Trustee’s Disclaimer.

The Trustee 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 in the Securities other than its 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 it is known to the Trustee, the Trustee shall mail to all Holders of Securities of that series a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment on any such Security, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of such Securityholders.

Section 7.06 Reports by Trustee to Holders.

Within 60 days after May 15 in each year, the Trustee with respect to any series of Securities shall mail to Holders of Securities of that series as provided in TIA Section 313(c) a brief report dated as of such May 15 that complies with TIA Section 313(a) (if such report is required by TIA Section 313(a)). The Trustee shall also comply with TIA Section 313(b)(2).

A copy of each report at the time of its mailing to Securityholders shall be mailed to the Company and filed with the Commission and each stock exchange on which any of the Securities are listed, as required by TIA Section 313(d). The Company shall notify the Trustee when the Securities are 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 as shall be agreed upon in writing for its services hereunder. The Company shall reimburse the Trustee upon written request for all reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee’s agents and counsel.

The Company shall indemnify each of the Trustee or any predecessor Trustee for any loss, liability, damage, claims, or expenses, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred by it, without negligence or bad faith on its part, in connection with the acceptance or administration of this Indenture and its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee in its capacity as Trustee, except money or property held in trust to pay principal and interest on particular Securities. Such lien will survive the satisfaction and discharge of this Indenture.

If the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(4) or (5) hereof occurs, the expenses and the compensation for the services will be intended to constitute expenses of administration under any applicable Bankruptcy Law.

This Section 7.07 shall survive the resignation or removal of the Trustee and the termination of this Indenture.

Section 7.08 Replacement of Trustee.

A resignation or removal of the Trustee with respect to one or more or all series of Securities and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

The Trustee may resign with respect to one or more or all series of Securities by so notifying the Company in writing. The Holders of a majority in principal amount of the then outstanding Securities of any series may remove the Trustee as to that series by so notifying the Trustee in writing and may appoint a successor Trustee with the Company’s consent. The Company may remove the Trustee with respect to one or more or all series of Securities if:

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

(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 becomes incapable of acting.

If, as to any series of Securities, the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee for that series. Within one year after the successor Trustee with respect to any series takes office, the Holders of a majority in principal amount of the then outstanding Securities of that series may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee as to a particular series 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 then outstanding Securities of that series may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10 hereof with respect to any series, any Holder of Securities of that series who satisfies the requirements of TIA Section 310(b) may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for that series.

A successor Trustee as to any series of Securities shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Immediately after that, the retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee (subject to the lien provided for in Section 7.07 hereof), 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 as to that series. The successor Trustee shall mail a notice of its succession to the Holders of Securities of that series.

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

In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee, and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and that (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts, and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) shall contain such provisions as shall be necessary or desirable to confirm that all the rights, powers, trusts, and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary or desirable to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; provided, however, that nothing herein or in such supplemental indenture shall constitute such Trustee co-trustees of the same trust and that each such Trustee shall be trustee of a trust hereunder separate and apart from any trust hereunder administered by any other such Trustee.

Upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed, or conveyance, shall become vested with all the rights, powers, trusts, and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

Section 7.09 Successor Trustee by Merger, etc.

If the Trustee as to any series of Securities consolidates, merges, or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee as to that series.

Section 7.10 Eligibility; Disqualification.

Each series of Securities shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2), and (5). The Trustee as to any series of Securities shall always have a combined capital and surplus of at least $25,000,000 as set forth in its most recent published annual report of condition. The Trustee is subject to TIA Section 310(b).

Section 7.11 Preferential Collection of Claims Against Company.

The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

ARTICLE 8

SATISFACTION AND DISCHARGE; DEFEASANCE

Section 8.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect with respect to any series of Securities issued 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 Notes for whose payment money has theretofore 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 by reason of the making of a notice of redemption or otherwise or will become due and payable within one year 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, cash in U.S. dollars, non-callable U.S. Government Obligations, foreign government obligations, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, and accrued interest to the date of Maturity or redemption;

(2) no Default or Event of Default with respect to such series of Securities shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which the Company or any Guarantor is a party to or by which the Company or any Guarantor is bound;

(3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture with respect to such series of Securities; and

(4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Securities of such series at Maturity or the redemption date, as the case may be. In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding, the satisfaction and discharge of this Indenture with respect to a series of Securities, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the provisions of Section 8.06 shall survive.

For purposes of this Indenture, the term “foreign government obligations” means, with respect to Securities of any series that are denominated in a currency other than United States dollars, (a) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged, which are not callable or redeemable at the option of the issuer thereof; or (b) obligations of a person controlled or supervised by or acting as an agency or instrumentality of that government, the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by that government, which are not callable or redeemable at the option of the issuer thereof.

Section 8.02 Option to Effect Legal Defeasance or Covenant Defeasance.

Unless Section 8.03 or 8.04 is otherwise specified to be inapplicable to Securities of a series, the Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, elect to have either Section 8.03 or 8.04 hereof be applied to all outstanding Securities of any such series upon compliance with the conditions set forth below in this Article 8.

Section 8.03 Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.02 hereof of the option applicable to this Section 8.03, the Company and any Guarantor shall, subject to the satisfaction of the conditions set forth in Section 8.05 hereof, be deemed to have been discharged from their respective obligations with respect to all outstanding Securities of any series on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and any Guarantor shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities of a series, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.06 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Securities 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 to receive solely from the trust fund described in Section 8.05 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, and interest on such Securities when such payments are due, (b) the Company’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties, and immunities of the Trustee hereunder and the Company’s or any Guarantors’ obligations in connection therewith, and (d) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.03 notwithstanding the prior exercise of its option under Section 8.04 hereof.

Section 8.04 Covenant Defeasance.

Upon the Company’s exercise under Section 8.02 hereof of the option applicable to this Section 8.04, the Company or any Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.05 hereof, be released from their respective obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.06, and 4.07, and Section 5.01 hereof with respect to the outstanding Securities of any series on and after the date the conditions set forth in Section 8.05

are satisfied (hereinafter, “Covenant Defeasance”), 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 (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 any series, the Company or 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. In addition, upon the Company’s exercise under Section 8.02 hereof of the option applicable to this Section 8.04 hereof, subject to the satisfaction of the conditions set forth in Section 8.05 hereof, Sections 6.01(3) through 6.01(6) hereof shall not constitute Events of Default.

Section 8.05 Conditions to Legal or Covenant Defeasance.

(a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable U.S. Government Obligations, foreign government obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, and interest on the outstanding Securities on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(b) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee 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 hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the 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;

(c) in the case of an election under Section 8.04 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the 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;

(d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of which will be used to defease the Securities pursuant to this Article 8 concurrently with such incurrence) or insofar as Sections 6.01(4) or 6.01(5) hereof is concerned, at any time in the period ending on the 91st day after the date of deposit;

(e) such Legal Defeasance or Covenant Defeasance shall 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;

(f) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying, or defrauding any other creditors of the Company; and

(g) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 8.06 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.07 hereof, all money and non-callable U.S. Government Obligations or foreign government obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.06, the “Trustee”) pursuant to Section 8.01 or Section 8.05 hereof in respect of the outstanding Securities shall be held in trust and applied by the Trustee, 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 Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee, or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations or foreign government obligations deposited pursuant to Section 8.05 hereof 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 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable U.S. Government Obligations or foreign government obligations held by it as provided in Section 8.05 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.05(a) hereof), 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 8.07 Repayment to Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Securities and remaining unclaimed for two years after such principal and premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Securities shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.08 Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable U.S. Government Securities in accordance with Section 8.03 or 8.04 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.03 or 8.04 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.03 or 8.04 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Securities following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

Subject to Section 6.07, the Company and the Trustee as to any series of Securities may amend this Indenture or the Securities of that series with the written consent of the Holders of a majority in principal amount of the then outstanding Securities of each series affected by the amendment, with each such series voting as a separate class. The Holders of a majority in principal amount of the then outstanding Securities of any series may also waive compliance in a particular instance by the Company with any provision of this Indenture with respect to that series or the Securities of that series; provided, however, that without the consent of each Securityholder affected, an amendment or waiver may not:

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

(2) reduce the amount of, or postpone the date fixed for, the payment of any sinking fund or analogous provision;

(3) reduce the rate of, or change the time for payment of interest on, any Security;

(4) reduce the principal of or change the fixed Maturity of any Security or waive a redemption payment or alter the redemption provisions with respect thereto;

(5) make any Security payable in money other than that stated in the Security (including defaulted interest);

(6) reduce the principal amount of Original Issue Discount Securities payable upon acceleration of the Maturity thereof;

(7) make any change in Section 6.04, 6.07, or this Section 9.02;

(8) waive a default in the payment of the principal of, or interest on, any Security, except to the extent otherwise provided for in Section 6.02 hereof;

(9) change the place of payment on a Security;

(10) change the currency or currencies of payment of the principal of, and any premium, make-whole payment, interest, or additional amounts on, any Security;

(11) reduce the percentage of Holders of Securities whose consent is needed to modify or amend this Indenture;

(12) reduce the percentage of the Holders of outstanding Securities of any series necessary to modify or amend this Indenture, to waive compliance with provisions of this Indenture or defaults and their consequences under this Indenture, or to reduce the quorum or voting requirements contained in this Indenture;

(13) make any change that adversely affects the right to convert or exchange any Security other than as permitted by this Indenture or decrease the conversion or exchange rate or increase the conversion or exchange price of any such Security; or

(14) waive a redemption payment with respect to any Security.

An amendment or waiver under this Section that waives, changes, or eliminates any covenant or other provision of this Indenture that has expressly been included solely for the benefit of one or more particular series of Securities, or that modifies the rights of the Holders of Securities 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 Securities of any other series.

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

The Company shall mail supplemental indentures to Holders upon request. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

Section 9.03 Revocation and Effect of Consents.

Until an amendment or waiver becomes effective, a consent to it by a Holder of a Security 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; provided, however, any such Holder or subsequent Holder may revoke the consent as to his Security or portion of a Security if the Trustee receives the written notice of revocation before the date on which the amendment, supplement, or waiver becomes effective. An amendment, supplement, or waiver shall become effective in accordance with its terms and thereafter shall bind every Holder of Securities of that series.

Section 9.04 Notation on or Exchange of Securities.

If an amendment, supplement, or waiver changes the terms of a Security: (a) the Trustee may require the Holder of the Security to deliver it to the Trustee, the Trustee may, at the written direction of the Company and at the Company’s expense, place an appropriate notation on the Security about the changed terms and return it to the Holder and the Trustee may place an appropriate notation on any Security thereafter authenticated; or (b) if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Failure to make the appropriate notation or issue a new Security shall not affect the validity and effect of such amendment, supplement, or waiver.

Section 9.05 Trustee to Sign Amendments, etc.

Subject to the preceding sentence, the Trustee shall sign any amendment or supplemental indenture if the same does not adversely affect the rights, duties, liabilities, or immunities of the Trustee. The Trustee may, but shall not be obligated to, execute any such amendment, supplement, or waiver that affects the Trustee’s own rights, duties, liabilities, or immunities under this Indenture or otherwise. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01) shall be fully protected in relying upon, in addition to the documents required by Section 11.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.
