may be required to comply with the rules of any securities exchange or Depository therefor or as may, consistently herewith, be determined by the officers executing such Securities, as evidenced by their execution thereof. If the form of Securities of any series is established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Company Order contemplated by Section 2.03 for the authentication and delivery of such Securities.

The Securities shall be issued initially in the form of one or more permanent Global Securities in registered form and deposited with the Trustee, as custodian for the Depository. The aggregate principal amount of any Global Security may from time to time be increased or decreased by adjustments made on the records of the Trustee, as custodian for the Depository.

The Securities may have notations, legends or endorsements required by law, rule or usage to which the Company is subject.

The terms and provisions contained in the Securities shall constitute, and are expressly made, a part of this Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and agree to be bound thereby.

SECTION 2.03. Execution and Authentication .

The Securities shall be executed on behalf of the Company by its Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President, Treasurer, Assistant Treasurer, Controller, Assistant Controller, Secretary, Assistant Secretary or any Vice President. The signature of any of these officers on the Securities may be manual or facsimile.

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

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.01 and 2.02, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Opinion of Counsel stating,

(1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.02, that such form has been established in conformity with the provisions of this Indenture;

(2) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 2.01, that such terms have been established in conformity with the provisions of this Indenture; and

(3) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accor-

dance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 2.01 and of the preceding paragraph, if all Securities of any series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 2.01 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued.

Each Security shall be dated the date of its authentication.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 2.12, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

The Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be specified as contemplated by Section 2.01. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

SECTION 2.04. Registrar and Paying Agent .

The Company shall maintain an office or agency in a Place of Payment where Securities may be presented for registration of transfer or for exchange (the “ Registrar ”), and an office or agency where Securities may be presented for payment (the “ Paying Agent ”) and an office or agency where notices and demands to or upon the Company, if any, in respect of the Securities and this Indenture may be served. The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more additional Paying Agents. The term “Paying Agent” includes any additional Paying Agent.

The Company shall enter into an appropriate agency agreement, which shall incorporate the provisions of the TIA, with any Agent that is not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any such Agent. If the Company fails to maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such and shall be entitled to appropriate compensation in accordance with Section 7.07.

The Company initially appoints the Trustee as Registrar, Paying Agent and Agent for service of notices and demands in connection with the Securities and this Indenture and the Company may change the Paying Agent without prior notice to the Holders. The Company or any of its Subsidiaries may act as Paying Agent.

SECTION 2.05. Paying Agent To Hold Money in Trust .

Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal of or premium or interest on the Securities (whether such money has been paid to it by the Company or any other obligor on the Securities), and the Company and the Paying Agent shall notify the Trustee of any Default by the Company (or any other obligor on the Securities) in making any such payment. Money held in trust by the Paying Agent need not be segregated except as required by law and in no event shall the Paying Agent be liable for any interest on any money received by it hereunder; provided that if the Company or an Affiliate thereof acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require the Paying Agent to pay all money held by it to the Trustee and account for any funds disbursed and the Trustee may at any time during the continuance of any Event of Default specified in Section 6.01(1) or (2), upon written request to the Paying Agent, require the Paying Agent to pay forthwith all money so held by it to the Trustee and to account for any funds disbursed. Upon making such payment, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.06. Holder Lists .

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of the Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least five Business Days before each Interest Payment Date for Securities of any series, 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 the Holders of Securities of such series; provided that, as long as the Trustee is the Registrar, no such list need be furnished.

SECTION 2.07. Transfer and Exchange .

Subject to Section 2.16, when Securities of any series are presented to the Registrar with a request from the Holder of such Securities to register a transfer or to exchange them for an equal principal amount of Securities of such series of other authorized denominations, the Registrar shall register the transfer as requested. Every Security presented or surrendered for registration of transfer or exchange shall 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 attorneys duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall issue and execute and the Trustee shall authenticate new Securities of the same series evidencing such transfer or exchange at the Registrar’s request. No service charge shall be made to the Holder for any registration of transfer or exchange. The Company may require from the Holder payment of a sum sufficient to cover any transfer taxes or other governmental charge that may be imposed in relation to a transfer exchange, but this provision shall not apply to any exchange pursuant to Section 2.11, 3.06 or 8.05 (in which events the Company shall be responsible for the payment of such taxes). The Registrar shall not be required to exchange or register a transfer of any Security for a period of 15 days immediately preceding the redemption of Securities of such series, except the unredeemed portion of any Security being redeemed in part.

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

Except as expressly provided herein, neither the Trustee nor the Registrar shall have any duty to monitor the Company’s compliance with or have any responsibility with respect to the Company’s compliance with any Federal or state securities laws.

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

Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depository.

SECTION 2.08. Replacement Securities .

If a mutilated Security is surrendered to the Registrar or the Trustee, or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security of the same series if the Holder of such Security furnishes to the Company and the Trustee evidence reasonably acceptable to them of the ownership and the destruction, loss or theft of such Security and if the requirements of Section 8-405 of the New York Uniform Commercial Code as in effect on the date of this Indenture are met. If required by the Trustee or the Company, an indemnity bond shall be posted, sufficient in the judgment of all to protect the Company, the Trustee or any Paying Agent from any loss that any of them may suffer if such Security is replaced. The Company may charge such Holder for the Company’s reasonable out-of-pocket expenses in replacing such Security and the Trustee may charge the Company for the Trustee’s expenses (including, without limitation, attorneys’ fees and disbursements) in replacing such Security. Every replacement Security shall constitute a contractual obligation of the Company.

SECTION 2.09. Outstanding Securities .

The Securities outstanding at any time are all Securities that have been authenticated by the Trustee except for (a) those canceled by it, (b) those delivered to it for cancellation, (c) to the extent set forth in Sections 9.01 and 9.02, on or after the date on which the conditions set forth in Section 9.01 or 9.02 have been satisfied, those Securities theretofore authenticated and delivered by the Trustee hereunder and (d) those described in this Section 2.09 as not outstanding. Subject to Section 2.10, a Security does not cease to be outstanding because the Company or one of its Affiliates holds the Security.

If a Security is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser in whose hands such Security is a legal, valid and binding obligation of the Company.

If the Paying Agent holds, in its capacity as such, on any Maturity Date, money sufficient to pay all accrued interest and principal with respect to the Securities payable on that date and is not pro-

hibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10. Treasury Securities .

In determining whether the Holders of the required principal amount of Securities of any series have concurred in any declaration of acceleration or Notice of Default or direction, waiver or consent or any amendment, modification or other change to this Indenture, Securities of such series owned by the Company or any other Affiliate of the Company shall be disregarded as though they were not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent or any amendment, modification or other change to this Indenture, only Securities of such series as to which a Responsible Officer of the Trustee has actually received an Officers’ Certificate stating that such Securities are so owned shall be so disregarded. Securities of such series so owned which have been pledged in good faith shall not be disregarded if the pledgee established to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Securities and that the pledgee is not the Company any other obligor on such Securities or any of their respective Affiliates.

SECTION 2.11. Temporary Securities .

Until definitive Securities of any series are prepared and ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities of such series. Temporary Securities shall be substantially in the form of definitive Securities of the same series 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 of any series in exchange for temporary Securities of such series. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as definitive Securities of such series.

SECTION 2.12. 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, replacement or cancellation and shall deliver such canceled Securities to the Company upon request therefor. The Company may not reissue or resell, or issue new Securities of any series to replace Securities of such series that the Company has redeemed or paid, or that have been delivered to the Trustee for cancellation.

SECTION 2.13. Defaulted Interest .

If the Company defaults on a payment of interest on any series of Securities, it shall pay the defaulted interest, plus (to the extent permitted by law) any interest payable on the defaulted interest (including post-petition interest in any proceeding under any Bankruptcy Law), in accordance with the terms hereof, to the Persons who are Holders of such series of Securities on a subsequent special record date, which date shall be at least five Business Days prior to the payment date. The Company shall fix such special record date and payment date in a manner satisfactory to the Trustee. At least 10 days before such special record date, the Company shall mail to each Holder of such series of Securities a notice that states the special record date, the payment date and the amount of defaulted interest, and interest payable on defaulted interest, if any, to be paid. The Company may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements (if applicable) of any securities exchange on which the Securities of such series may be listed and, upon such notice as may be required by such

exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this sentence, such manner of payment shall be deemed practicable by the Trustee.

SECTION 2.14. CUSIP Number .

The Company in issuing the Securities of any series may use a “CUSIP” number, and if so, such CUSIP number shall be included in notices of redemption or exchange as a convenience to Holders of such series; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Securities, and that reliance may be placed only on the other identification numbers printed on the Securities. The Company shall promptly notify the Trustee of any such CUSIP number used by the Company in connection with the issuance of the Securities and of any change in the CUSIP number.

SECTION 2.15. Deposit of Moneys .

Prior to 11:00 a.m., New York City time, on each Interest Payment Date and Maturity Date, the Company shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date or Maturity Date, as the case may be, in a timely manner which permits the Trustee to remit payment to the Holders on such Interest Payment Date or Maturity Date, as the case may be. The principal and interest on Global Securities shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole Holder of the Global Securities represented thereby. The principal and interest on Physical Securities shall be payable, either in person or by mail, at the office of the Paying Agent.

SECTION 2.16. Book-Entry Provisions for Global Securities .

(a) Each Global Security authenticated under this Indenture shall be registered in the name of the Depository designated for such Global Security or a nominee thereof and delivered to such Depository or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture

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

(c) Transfers of Global Securities shall be limited to transfer in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Securities of any series may be transferred or exchanged for Physical Securities of such series in accordance with the rules and procedures of the Depository. In addition, a Global Security shall be exchangeable for Physical Securities if (i) the Depository (x) notifies the Company that it is unwilling or unable to continue as depository for such Global Security or (y) has ceased to be a clearing agency registered under the Exchange Act, and, with respect to (x) or (y), the Company thereupon fails to appoint a successor depository within 90 days of such notice or cessation, (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of such Physical Securities in exchange for any or all of the Securities of any series represented by the Global Securities of such series or (iii) there shall

have occurred and be continuing an Event of Default with respect to the Securities of any series. In all cases, Physical Securities delivered in exchange for any Global Security or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depository (in accordance with its customary procedures).

(d) In connection with any transfer or exchange of a portion of the beneficial interest in any Global Security to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Physical Securities are to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Security of such series in an amount equal to the principal amount of the beneficial interest in the Global Security of such series to be transferred, and the Company shall execute, and the Trustee shall upon receipt of a written order from the Company authenticate and make available for delivery, one or more Physical Securities of like tenor and amount.

(e) In connection with the transfer of Global Securities of any series as an entirety to beneficial owners pursuant to paragraph (b), the Global Securities of such series shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in writing in exchange for its beneficial interest in the Global Securities of such series, an equal aggregate principal amount of Physical Securities of authorized denominations.

(f) Any beneficial interest in one of the Global Securities of any series that is transferred to a Person who takes delivery in the form of an interest in another Global Security of such series shall, upon transfer, cease to be an interest in such Global Security and become an interest in such other Global Security and, accordingly, shall thereafter be subject to all transfer restrictions and other procedures applicable to beneficial interests in such other Global Security for as long as it remains such an interest.

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

(h) None of the Company, the Trustee, any Paying Agent or any Registrar will have any responsibility or liability for any aspect of Depository records relating to, or payments made on account of, beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any Depository records relating to such beneficial ownership interests, or for transfers of beneficial interests in the Securities or any transactions between the Depositary and beneficial owners.

SECTION 2.17. Legend for Global Security .

Unless otherwise specified as contemplated by Section 2.01 for the Securities evidenced thereby, every Global Security authenticated and delivered 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 a Depository or a nominee thereof. This Security may not be exchanged in whole or in part for a Security registered, and no transfer of this Security in whole or in part may be registered, in the name of any Person other than such Depository or a nominee thereof, except in the limited circumstances described in the Indenture.

SECTION 2.18. Computation of Interest .

Except as otherwise specified as contemplated by Section 2.01, interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 2.19. Calculation of Original Issue Discount .

The Company shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on outstanding series of Securities as of the end of such year and (ii) such other specific information relating to such original issue discount as may then be relevant under the Internal Revenue Code of 1986, as amended from time to time.

SECTION 2.20. Record Dates .

(a) The Company may set any day as a record date for the purpose of determining the Holders of outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 7.06.

(b) The Trustee may set any day as a record date for the purpose of determining the Holders of outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 6.02, (iii) any request to institute proceedings referred to in Section 6.06(2) or (iv) any direction referred to in Section 6.05, in each case with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of outstanding Securities of such series 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 that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the

applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series.

(c) With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities of the relevant series, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

(d) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.
