The Securities

Section 2.01. Terms and Form.

The Securities may be issued from time to time in one or more Series. Each Series shall be limited to such aggregate principal amount, shall bear the title and interest at the rates and from the dates, shall mature at the times, shall or may be redeemable at the prices and upon the terms, and shall contain or be subject to all terms as shall be established in an indenture supplemental hereto or by or pursuant to a Board Vote (and, to the extent not set forth in the Board Vote, in an Officers’ Certificate detailing the adoption of terms pursuant to the Board Vote). Securities of a Series shall be substantially identical except as to denomination and except as may be otherwise provided in a Board Vote and/or an Officers’ Certificate or in an indenture supplemental hereto. In case of Securities of a Series to be issued from time to time, the Officers’ Certificate may provide for the method by which specified terms (such as interest rate, maturity date, record date or date from which interest shall accrue) are to be determined.

The Securities of each Series hereunder shall be substantially in the form set forth in Exhibit A or in such form, including with respect to whether such Series shall be issued in whole or in part in the form of one or more Global Securities and the Depository for such Global Security or Securities, as shall be established pursuant to a Board Vote (and, to the extent not set forth in the Board Vote, in an Officers’ Certificate detailing the adoption of such form) or one or more indenture supplements to this Indenture, in each case, with such insertions, omissions, substitutions, and other variations as are required or permitted by this Indenture, such Board Vote or such indenture supplement. If a form of any Security is approved by a Board Vote, such Officers’ Certificate shall also state that all conditions precedent relating to the authentication and delivery of such Security have been complied with and shall be accompanied by a copy of the Board Vote by or pursuant to which the form of such Security has been approved. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall approve the form of the Securities and any notation, legend or endorsement on them, such approval to be conclusively evidenced by the execution of such Securities. Unless the form of a Security of a Series provides otherwise, each Security shall be dated the date of its authentication.

Unless the form of a Security of a Series provides otherwise, the Securities of such Series shall be issued in denominations of $1,000 or multiples thereof.

Section 2.02. Form of Legend for Global Security.

Any Global Security issued hereunder shall bear a legend in substantially the following form:

“This Security is a Global Security within the meaning of the Indenture hereinafter referred to and is registered in the name of the Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a person other than the Depository or its nominee only in the limited circumstances described in the Indenture, and may not be transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.”

Section 2.03. Execution and Authentication.

Two Officers shall sign the Securities for the Company and may employ facsimile signatures. The Company’s seal shall be impressed, affixed or reproduced on the Securities.

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

The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is unlimited. The Trustee shall authenticate Securities for original issue upon (or in accordance with such procedures acceptable to the Trustee set forth in) a written order of the Company signed by two Officers or by an Officer and an Assistant Treasurer of the Company.

A Security shall not be valid until the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. The Trustee’s authentication shall be in the following form (except that where applicable any successor or additional Trustee’s name for Securities of a Series shall be substituted for the Trustee named below):

This is one of the Securities of the Series designated therein issued under the within mentioned Indenture.


U.S. BANK NATIONAL ASSOCIATION, as Trustee

By
Name:
Title:

Section 2.04. Registrar and Paying Agent.

The Company shall designate a Registrar who shall maintain an office or agency where Securities may be presented for registration of transfer and where Securities may be presented for exchange (the “Registrar”) and a paying agent who shall maintain an office or agency where Securities may be presented for payment (the “Paying Agent”). Initially, U.S. Bank National Association, Corporate Trust Services, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, will act as the Registrar and Paying Agent. The Registrar shall keep a register of the Securities and of their transfer and exchange. With the consent of the Trustee, which shall not be unreasonably withheld, the Company may designate one or more co-registrars and one or more Paying Agents. The term “Registrar” includes any additional co-registrar. The term “Paying Agent” includes any additional paying agent. The Company shall notify the Trustee 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, the Trustee shall act as such.

Section 2.05. Paying Agent to Hold Money in Trust.

The Company, by written agreement, shall require each Paying Agent other than the Trustee to agree that the Paying Agent will hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of and premium, if any, or interest on the Securities, and will notify the Trustee of any default by the Company in making any such payment. If the Company acts as Paying Agent, it shall segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon doing so the Paying Agent shall have no further liability for the money.

Section 2.06. 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. If the Trustee is not the Registrar with respect to a Series of Securities, the Company shall furnish to the Trustee any information in the possession or control of the Company (a) on or before each semi-annual interest payment date of any Series of Securities, and (b) 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.

Section 2.07. Transfer and Exchange.

When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested in the manner provided in this Section 2.07.

Every Security presented or surrendered for registration of transfer or exchange shall (if so required by the Company or the Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by the Holder thereof or his attorney duly authorized in writing. To permit transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. The Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed for any exchange or transfer but not for any exchange pursuant to Section 2.10, 3.06 or 9.05.

The Company shall not be required: (i) to issue, register the transfer of or exchange Securities of any Series during a period beginning at the opening of business 15 days before the day of selection for redemption of Securities of that Series under Section 3.02 and ending at the close of business on the day of the mailing of notice of redemption, or (ii) to register the transfer of, or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

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 this Section 2.07 for Securities registered in the names of Holders other than the Depository for such Security or its nominee only if: (i) such Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and, in either such case, the Company fails to appoint a successor Depository within 90 days of such event, (ii) the Company executes and delivers to the Trustee an Officers’ Certificate that such Global Security shall be so exchangeable or (iii) a Default shall have occurred and be continuing with respect to the Securities represented by such Global Security. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as the Depository 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 Section 2.07, a Global Security may not be transferred except as a whole by the Depository with respect to such Global Security to a nominee of such Depository, by a nominee of such Depository to such Depository or another nominee of such Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

Section 2.08. Replacement Securities.

If the Holder of a mutilated Security surrenders such Security to the Trustee or if the Holder of a Security presents evidence satisfactory to the Company and the Trustee that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security of the same Series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such Security has or is about to become due and payable, the Company may pay the Security instead of issuing a new Security. If required by the Company or the Trustee, such Holder shall provide an indemnity bond which must be sufficient in the judgment of the party requiring it 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 the Holder for its expenses in replacing a Security.

Every replacement Security is an additional obligation of the Company.

Section 2.09. Outstanding Securities.

Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those Securities of any Series for which the Company has made a deposit in accordance with Section 8.01 and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate holds the Security. See Section 10.06.

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 bona fide purchaser.

If the Paying Agent holds on a redemption date or maturity date money sufficient to pay Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue.

Section 2.10. Temporary Securities.

Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities.

Section 2.11. Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall destroy such cancelled Securities and shall furnish the Company with a certificate of destruction. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation.

Section 2.12. Defaulted Interest.

If the Company defaults in the payment of interest on any Series of the Securities, it shall pay the defaulted interest, plus any interest payable on such defaulted interest to the extent permitted by law, to persons who are Holders of Securities of such Series on a subsequent special record date. The Company shall fix the special record date and the payment date. At least 15 days before such special record date, the Company shall notify the Trustee and each Holder of such special record date, the payment date and the amount of interest to be paid. The Company may pay defaulted interest in any other lawful manner.

ARTICLE THREE

Redemption

Section 3.01. Notices to Trustee.

If the Company wants to redeem any Series of Securities pursuant to the terms of the Securities of that Series, the Company shall notify the Trustee of the redemption date and the principal amount of the Securities to be redeemed.

Each such notice shall be accompanied by an Officers’ Certificate stating that the conditions to such redemption as provided in such Security and in this Indenture have been complied with. If the Company elects to redeem less than all the Securities of a Series, the Company shall notify the Trustee of such redemption date and of the principal amount of such Securities to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 3.02.

If any Series of Securities by its terms is redeemable pursuant to the operation of a sinking fund, the Company shall notify the Trustee by an Officers’ Certificate of the amount of the next sinking fund payment and the portion of such payment which is to be satisfied by delivering and crediting Securities of the same Series pursuant to Section 3.05.

If the Company wants to credit against any mandatory redemption Securities of the same Series it has not previously delivered to the Trustee for cancellation, it shall deliver the Securities with such Officers’ Certificate.

The Company shall give each notice or Officers’ Certificate provided for in this Section at least 30 days before the redemption date (unless shorter notice is satisfactory to the Trustee).

Any notice of redemption given to the Trustee may be canceled by written notice to the Trustee at any time prior to the mailing of the notice of redemption to the Holders of Securities to be redeemed and upon any such cancellation shall thereupon be void and of no effect.

Section 3.02. Selection of Securities to be Redeemed.

If less than all the Securities of a Series are to be redeemed, the Trustee shall select the Securities to be redeemed by a method the Trustee considers fair and appropriate. The Trustee shall make the selection from Securities of such Series outstanding not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities of such Series that have denominations larger than $1,000. Securities and portions of them it selects shall be in amounts of $1,000 or multiples of $1,000. 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.

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail (or deliver by electronic transmission in accordance with the applicable procedures of the Depository) to each Holder of Securities to be redeemed.

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

(1) the redemption date;

(2) the redemption price (or the method of calculating or determining the redemption price) and the accrued interest, if any;

(3) the CUSIP number and ISIN, if any, of such Securities;

(4) if less than all Securities of a Series outstanding are to be redeemed, the identification (and, if any Security is to be redeemed in part, the principal amount) of the particular Security to be redeemed;

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

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

(7) that interest on Securities called for redemption ceases to accrue on and after the redemption date; and

(8) that the redemption is pursuant to a sinking fund, if that is the case.

At the Company’s request at least five days prior to the date the notice of optional redemption is to be given (unless a shorter time period shall be acceptable to the Trustee), the Trustee shall give such notice of redemption to each Holder of Securities to be redeemed in the Company’s name and at the Company’s expense.

Section 3.04. Effect of Notice of Redemption.

Once notice of redemption is mailed (or delivered by electronic transmission in accordance with the applicable procedures of the Depository), Securities called for redemption become due and payable on the redemption date and at the applicable redemption price. Upon surrender to the Paying Agent, such Securities shall be paid at the applicable redemption price plus accrued interest, if any, to the redemption date; provided, however, that any regular payment of interest becoming due on the redemption date shall be payable to the Holders of such Securities in accordance with their terms.

Section 3.05. Deposit of Redemption Price.

On or before the redemption date, the Company shall deposit with the Paying Agent (or if the Company is its own Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date.

Unless any Security by its terms prohibits any sinking fund payment obligation from being satisfied by delivering and crediting Securities (including Securities redeemed otherwise than through a sinking fund), the Company may deliver such Securities to the Trustee for crediting against such payment obligation in accordance with the terms of such Securities and this Indenture.

Section 3.06. Securities Redeemed in Part.

Upon surrender of a Security that is redeemed in part, the Trustee shall authenticate and deliver to the Holder a new Security of the same Series equal in principal amount to the unredeemed portion of the Security surrendered.

ARTICLE FOUR

Covenants

Section 4.01. Certain Definitions.

“Attributable Debt” means, as of the date of determination, the present value of rent due under a lease for the remaining primary term of the lease. Rent shall be discounted to present value from the due date of each installment to the date of determination at the actual interest factor included in the rent or, if the interest factor cannot readily be determined, at 12% per annum. Rent is the lesser of: (1) rent for the remaining primary term of the lease assuming it is not earlier terminated, and (2) rent from the date of determination until the first permitted termination date under the lease plus the termination payment then due, if any. The remaining primary term of a lease includes any period for which the lease has been extended. Rent does not include: (1) amounts payable for maintenance, repairs, insurance, taxes, assessments, water rates, and similar charges, or (2) contingent rent, such as that based on sales, maintenance and repairs, insurance, taxes, assessments or similar charges.

Successor Corporation

Section 5.01. When Company May Merge, etc.

The Company may consolidate with or merge into, or transfer all or substantially all of its assets to, one person or entity if:

(1) the person or entity assumes by supplemental indenture all the obligations of the Company under the Securities and this Indenture; thereafter all such obligations of the predecessor corporation shall terminate;

(2) immediately after giving effect to the transaction, no Default would occur and be continuing; and

(3) the entity formed by or surviving such transaction, in the case of a consolidation or merger, and the transferee, in the case of a transfer, is a person or entity organized under the laws of the United States of America, any State thereof, the District of Columbia, Canada, any province of Canada or any state which was a member of the European Union on December 31, 2003 (other than Greece).

Section 5.02. When Securities Must Be Secured.

If upon any such consolidation, merger or transfer any Principal Property would become subject to an attaching Lien that secures Debt, then before the consolidation, merger or transfer occurs, the Company by supplemental indenture shall secure the Securities by a direct Lien on all such Principal Property. The direct Lien shall have priority over the attaching Lien and over all other Liens on such Principal Property except the Liens already on it. The direct Lien may equally and ratably secure the Securities and any other obligation of the Company or a Subsidiary entitled to such security. The direct Lien may not secure an obligation of the Company or such a Subsidiary that is subordinated to the Securities. However, the Company need not comply with this Section if:

(1) the attaching Lien is permitted under any of clauses (1) through (9) of Section 4.03; or

(2) the Company or a Restricted Subsidiary under the next to last paragraph of Section 4.03 could create a Lien on the Principal Property to secure Debt at least equal in amount to that secured by the attaching Lien.

ARTICLE SIX

Defaults and Remedies

Section 6.01. Events of Default.

Unless the form of a Security of a Series provides otherwise, an “Event of Default” occurs with respect to Securities of any Series if:

(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 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 or otherwise, provided that in the case of default in the making or satisfaction of any sinking fund payment, such default continues for a period of 30 days;

(3) the Company fails to comply with any of its other agreements in the Securities of that Series or this Indenture (other than a default which has expressly been included in this Indenture solely for the benefit of a Series of Securities other than that Series) and the default continues for the period and after the notice specified below;

(4) an event of default, as defined in any mortgage, indenture or instrument under which there is or may be issued indebtedness of the Company or any Restricted Subsidiary for money borrowed (including an Event of Default with respect to a Security

of any Series hereunder) in the principal amount exceeding $100,000,000, shall occur with the result that such indebtedness shall have been declared due and payable prior to the date on which it would otherwise become due and payable, but if any such default is cured by the Company or such Restricted Subsidiary or is waived by the specified percentage of holders of such mortgage, indenture or instrument entitled so to waive, then the Event of Default under this Indenture by reason of such default shall be deemed to have been cured;

(5) 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 from claims against it in an involuntary case;

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

(6) 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

and such order or decree remains unstayed and in effect for 90 days; or

(7) any other Event of Default provided for Securities of that Series occurs.

A Default with respect to any Series of Securities under clause (3) is not an Event of Default until the Trustee notifies the Company or the Holders of at least 25% in principal amount of the outstanding Securities of that Series notify the Trustee and the Company of the Default and the Company does not cure the Default within 90 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.”

Section 6.02. Acceleration.

If an Event of Default with respect to Securities of any Series occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities of that Series by notice to the Company and the Trustee, may declare that the principal of and accrued interest (or, if any of the Securities of that Series are original issue discount Securities, such portion of the principal amount of such Securities as may be specified

in the terms thereof), if any, shall be due and payable immediately. Upon such declaration, such principal (or specified amount) and interest shall be due and payable immediately. The Holders of a majority in principal amount of the outstanding Securities of that Series by notice to the Company and 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 (other than nonpayment of principal, interest or premium, if any, that has become due solely because of such acceleration) have been cured or waived.

Notwithstanding any provisions to the contrary contained in this Section 6.02 and in addition thereto, upon receipt by the Trustee of any declaration of acceleration, or rescission and annulment thereof, with respect to Securities of a Series all or part of which is represented by a Global Security, the Trustee shall establish a record date for determining Holders of outstanding Securities of such Series entitled to join in such declaration of acceleration, or rescission and annulment, as the case may be, which record date shall be at the close of business on the day the Trustee receives such declaration of acceleration, or rescission and annulment, as the case may be. The Holders on such record date, or their duly designated proxies, and only such Holders, shall be entitled to join in such declaration of acceleration, or rescission and annulment, as the case may be, whether or not such Holders remain Holders after such record date; provided, however, that unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having been obtained prior to the day which is 90 days after such record date, such declaration of acceleration, or rescission and annulment, as the case may be, shall automatically and without further action by any Holder be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new declaration of acceleration, or rescission or annulment thereof, as the case may be, that is identical to a declaration of acceleration, or rescission or annulment thereof, which has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 6.02.

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 by proceeding at law or in equity to collect the payment of principal of, interest or premium, if any, 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 of that Series 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. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law.

Section 6.04. Waiver of Past Defaults.

Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the outstanding Securities or any Series on behalf of the Holders of the outstanding Securities of that

Series by notice to the Trustee may waive an existing past Default or Event of Default and its consequences but such waiver shall not extend to any future Event of Default. When a Default or Event of Default is waived by the Holders of any Series of Securities, it is cured and stops continuing with respect to Securities of that Series.

Section 6.05. Control by Majority.

The Holders of a majority in principal amount of the outstanding Securities of any Series may direct the time, method and place of: (1) conducting any proceeding for any remedy available to the Trustee; or (2) exercising any trust or power conferred on the Trustee with respect to the Securities of that Series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, or subject to Section 7.01, that the Trustee determines would be unduly prejudicial to the rights of other Securityholders of that Series or that would involve the Trustee in personal liability.

Notwithstanding any provisions to the contrary contained in this Section 6.05, and in addition thereto, upon receipt by the Trustee of any direction with respect to Securities of a Series all or part of which is represented by a Global Security, the Trustee shall establish a record date for determining Holders of outstanding Securities of such Series entitled to join in such direction, which record date shall be at the close of business on the date the Trustee receives such direction. The Holders on such record date, or their duly designated proxies, and only such Holders, shall be entitled to join in such direction, whether or not such Holders remain Holders after such record date; provided, however, that unless such majority in principal amount shall have been obtained prior to the day which is 90 days after such record date, such direction shall automatically and without further action by any Holder be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder from giving, after expiration of such 90-day period, a new direction identical to a direction which has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 6.05.

Section 6.06. Limitation on Suits.

A Securityholder may pursue a remedy with respect to this Indenture or the Securities of that Series only if:

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

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

(3) such Holder or Holders offer 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 of indemnity; and

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

A Holder of any Series of Securities may not use any provision of this Indenture to prejudice the rights of another Holder of any Securities of that Series or to obtain a preference or priority over another Holder of any 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 of, interest and premium, if any, on the Security, on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing for 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, interest and any premium remaining unpaid on the Securities of that Series.

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 of Securities of any Series allowed in any judicial proceedings relative to the Company, its creditors or its property.

Section 6.10. Priorities.

If the Trustee collects any money pursuant to this Article with respect to Securities of any Series, it shall pay out the money in the following order:

FIRST: to the Trustee and any predecessor trustee of the Securities of that Series for amounts due under Section 7.07;

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

THIRD: to the Company.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10.

Section 6.11. Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, 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 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the Securities of any Series.

In all such cases the certificate of authentication shall have the same force and effect which the provisions of the Securities or this Indenture provided that certificates of authentication of the Trustee shall have, except that the right to adopt the certificate of authentication of any predecessor trustee for a Series of Securities or to authenticate Securities of a Series in the name of any predecessor trustee for that Series of Securities shall apply only to its successor or successors by merger, conversion or consolidation.
