If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. ARTICLE 2 THE NOTES SECTION 2.01 Form and Dating. The Notes and the Trustee's certificate of authentication to be borne by such Notes shall be substantially in the form annexed hereto as Exhibits A-1 and A-2, which are incorporated in and made a part of this Indenture.

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends and endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the notes may be listed or designated for issuance, or to conform to usage. (a) 144A Global Notes. Notes offered and sold within the United States to qualified institutional investors as defined in Rule 144A ("QIBs") in reliance on Rule 144A shall be issued, initially in the form of one or more 144A Global Notes, which shall be deposited with the Trustee at its Corporate Trust Office, as custodian for the Depositary (as defined below) and registered in the name of The Depository Trust Company ("DTC") or the nominee thereof (such depositary, or any successor thereto, and any such nominee being hereinafter referred to as the "Depositary"), duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the 144A Global Notes may from time to time be 11 increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided. (b) Certificated Notes. Notes not issued as interests in the Global Notes will be issued in certificated form substantially in the form of Exhibit A-2 attached hereto. Except as provided in this Section 2.01, 2.06 or 2.12, owners of beneficial interests in Global Notes will not be entitled to receive physical delivery of Certificated Notes. Notes offered and sold within the United States to Institutional Accredited Investors shall be issued, initially in the form of a Certificated Note, duly executed by the Company and authenticated by the Trustee as hereinafter provided. (c) Global Notes in General. Each Global Note shall represent such of the outstanding Notes as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions and conversions. Any adjustment of the aggregate principal amount of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 hereof and shall be made on the records of the Trustee and the Depositary as hereinafter provided. (d) Book-Entry Provisions. This Section 2.01(d) shall apply only to Global Notes deposited with or on behalf of the Depositary. The Company shall execute and the Trustee shall, in accordance with Section 2.02 hereof, authenticate and deliver initially one or more Global Notes that (a) shall be registered in the name of the Depositary or its nominee, (b) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary's instructions and (c) shall bear legends substantially to the following effect: "UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY 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 IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 12 TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF THE DEPOSITORY TRUST COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN ARTICLE TWO OF THE INDENTURE REFERRED TO ON THE REVERSE HEREOF." SECTION 2.02 Execution and Authentication. The Notes shall be executed on behalf of the Company by any Officer, under its corporate seal reproduced thereon. The signature of the Officer on the Notes may be manual or facsimile. Notes bearing the manual or facsimile signatures of individuals who were at the time of the execution of the Notes the proper Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of authentication of such Notes. No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder. The Trustee shall authenticate and deliver Notes for original issue in an aggregate principal amount of up to $300,000,000 upon a Company Order without any further action by the Company. The aggregate principal amount of Notes outstanding at any time may not exceed the amount set forth in the foregoing sentence, except as provided in Section 2.07. The Notes shall be issued only in registered form without coupons and only in denominations of $1,000 in principal amount and any integral multiple thereof. SECTION 2.03 Registrar, Paying Agent and Conversion Agent. The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange ("Registrar"), an office or agency where Notes may be presented for purchase or payment ("Paying Agent") and an office or agency where Notes may be presented for conversion (together with any other person authorized by the Company to convert Notes in accordance with the provisions of Article 10 hereof, the "Conversion Agent"). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company may have one or more co-Registrars, one or more additional Paying Agents and one or more additional Conversion Agents. The term Paying Agent includes any additional paying agent, including any named pursuant to Section 4.05. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 4.05. The Company shall enter into appropriate agency agreements with any Registrar, Paying Agent, Conversion Agent or co-Registrar, if other than the Trustee. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify 13 the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.06. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent and/or co-Registrar. The Company initially appoints the Trustee as Registrar, Conversion Agent and Paying Agent in connection with the Notes. SECTION 2.04 Paying Agent to Hold Money and Notes in Trust. Except as otherwise provided herein, on or prior to each due date of payments in respect of any Note, the Company shall deposit with the Paying Agent a sum of money (in immediately available funds if deposited on the due date) or Common Stock (pursuant to Section 3.10 hereof) sufficient to make such payments when so becoming due. The Company shall require each Paying Agent (if other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Noteholders or the Trustee all money and Common Stock held by the Paying Agent for the making of payments in respect of the Notes and shall notify the Trustee of any default by the Company in making any such payment. At any time during the continuance of any such default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money and Common Stock so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall segregate the money and Common Stock held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money and Common Stock held by it to the Trustee and to account for any funds and Common Stock disbursed by it. Upon doing so, the Paying Agent shall have no further liability for the money or Common Stock. SECTION 2.05 Noteholder 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 Noteholders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee at least semiannually on January 31 and July 31 a listing of Noteholders dated within 15 days of the date on which the list is furnished 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 Noteholders. SECTION 2.06 Transfer and Exchange. Subject to Section 2.12 hereof, (a) upon surrender for registration of transfer of any Note, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Noteholder or such Noteholder's attorney duly authorized in writing, at the office or agency of the company designated as Registrar or co-registrar pursuant to Section 2.03, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations, of a like aggregate principal amount. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Notes from the Noteholder requesting such transfer or exchange. 14 At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations, of a like aggregate principal amount, upon surrender of the Notes to be exchanged, together with a written instrument of transfer satisfactory to the Registrar duly executed by the Noteholder or such Noteholder's attorney duly authorized in writing, at such office or agency. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive. The Company shall not be required to make, and the Registrar need not register, transfers or exchanges of Notes selected for redemption (except, in the case of Notes to be redeemed in part, the portion thereof not to be redeemed) or any Notes in respect of which a Change of Control Repurchase Notice (as defined in Section 3.09(c)) has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Notes to be purchased in part, the portion thereof not to be purchased) or any Notes for a period of 15 days before the mailing of a notice of redemption of Notes to be redeemed. (b) Notwithstanding any provision to the contrary herein, so long as a Global Note remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Note, in whole or in part, shall be made only in accordance with Section 2.12 and this Section 2.06(b). Transfers of a Global Note shall be limited to transfers of such Global Note in whole, or in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. (c) Successive registrations and registrations of transfers and exchanges as aforesaid may be made from time to time as desired, and each such registration shall be noted on the register for the Notes. (d) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Notes upon transfer or exchange of Notes. (e) No Registrar shall be required to make registrations of transfer or exchange of Notes during any periods designated in the text of the Notes or in this Indenture as periods during which such registration of transfers and exchanges need not be made. (f) If Notes are issued upon the transfer, exchange or replacement of Notes subject to restrictions on transfer and bearing the legends set forth on the form of Note attached hereto as Exhibits A-1 and A-2 setting forth such restrictions (collectively, the "Legend"), or if a request is made to remove the Legend on a Note, the Notes so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an Opinion of Counsel, as may be reasonably required by the Company and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 under the Securities Act or that such Notes are not "restricted" within the meaning of Rule 144 under the Securities Act. Upon (i) provision of such satisfactory evidence, or (ii) notification by the Company to the Trustee and Registrar of the sale of such Note pursuant to a registration statement that is effective at the time of such sale, the 15 Trustee, at the written direction of the Company, shall authenticate and deliver a Note that does not bear the Legend. If the Legend is removed from the face of a Note and the Note is subsequently held by an Affiliate of the Company, the Legend shall be reinstated. SECTION 2.07 Replacement Notes. If (a) any mutilated Note is surrendered to the Trustee, or (b) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Company and the Trustee such Note or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Note, pay or purchase such Note, as the case may be. Upon the issuance of any new Notes under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Note issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder. The provisions of this Section 2.07 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes. SECTION 2.08 Outstanding Notes; Determinations of Holders' Action. Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it or delivered to it for cancellation, those paid pursuant to Section 2.07 and those described in this Section 2.08 as not outstanding. A Note does not cease to be outstanding because the Company or an Affiliate thereof holds the Note; provided, however, that in determining whether the Holders of the requisite principal amount of the outstanding Notes have given or concurred in any request, demand, authorization, direction, notice, consent or waiver hereunder, Notes owned by the Company or any other obligor upon the Notes or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Notes which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded. Subject to the foregoing, only Notes outstanding at the time of such determination shall be 16 considered in any such determination (including, without limitation, determinations pursuant to Articles 6 and 9). If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. If the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, or on the Business Day following the Change of Control Repurchase Date, or on Stated Maturity, money or securities, if permitted hereunder, sufficient to pay Notes payable on that date, then immediately after such Redemption Date, Change of Control Repurchase Date or Stated Maturity, as the case may be, such Notes shall cease to be outstanding and interest on such Notes shall cease to accrue; provided that, if such Notes are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made. If a Note is converted in accordance with Article 10, then upon conversion of such Note and in accordance with Section 10.02, such Note shall cease to be outstanding and interest shall cease to accrue on such Note. SECTION 2.09 Temporary Notes. Pending the preparation of definitive Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of such Notes. If temporary Notes are issued, the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Company designated for such purpose pursuant to Section 2.03, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized denominations. Until so exchanged the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Notes. SECTION 2.10 Cancellation. All Notes surrendered for payment, purchase by the Company pursuant to Article 3, conversion, redemption or registration of transfer or exchange shall, if surrendered to any person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. The Company may not issue new Notes to replace Notes it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in 17 this Section 2.10, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures in effect at the time and the Trustee shall deliver a certificate of destruction to the Company. SECTION 2.11 Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of the Note or the payment of any Redemption Price or Change of Control Repurchase Price in respect thereof, and interest thereon, for the purpose of conversion and for all other purposes whatsoever, whether or not such Note be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. SECTION 2.12 Global Notes. (a) Notwithstanding any other provisions of this Indenture or the Notes, (A) transfers of a Global Note, in whole or in part, shall be made only in accordance with Section 2.06 and Section 2.12(a)(i), (B) transfer of a beneficial interest in a Global Note for a Certificated Note shall comply with Section 2.06 and Section 2.12(a)(ii) below, and (C) transfers of a Certificated Note shall comply with Section 2.06 and Section 2.12(a)(iii) and (iv) below. (i) Transfer of Global Note. A Global Note may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that this clause (i) shall not prohibit any transfer of a Note that is issued in exchange for a Global Note but is not itself a Global Note. No transfer of a Note to any Person shall be effective under this Indenture or the Notes unless and until such Note has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Note effected in accordance with the other provisions of this Section 2.12(a). (ii) Restrictions on Transfer of a Beneficial Interest in a Global Note for a Certificated Note. A beneficial interest in a Global Note may not be exchanged for a Certificated Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a transfer of a beneficial interest in a Global Note in accordance with Applicable Procedures for a Certificated Note in the form satisfactory to the Trustee, together with: (a) so long as the Notes are Restricted Notes, certification, in the form set forth in Exhibit B-1, and, if requested by the Company or the Registrar, certification in the form set forth in Exhibit B-2, that such beneficial interest in the Global Note is being transferred to an Institutional Accredited Investor; (b) written instructions to the Trustee to make, or direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect a decrease in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such decrease; and 18 (c) if the Company or Registrar so requests, an opinion of counsel or other evidence reasonably satisfactory to them as to the compliance with the restrictions set forth in the Legend, then the Trustee shall cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of Notes represented by the Global Note to be decreased by the aggregate principal amount of the Certificated Note to be issued, shall issue such Certificated Note and shall debit or cause to be debited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the Certificated Note so issued. (iii) Transfer and Exchange of Certificated Notes. When Certificated Notes are presented to the Registrar with a request: (x) to register the transfer of such Certificated Notes; or (y) to exchange such Certificated Notes for an equal principal amount of Certificated Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Notes surrendered for transfer or exchange: (a) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and (b) so long as such Notes are Restricted Notes, such Notes are being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable: (A) if such Certificated Notes are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or (B) if such Certificated Notes are being transferred to the Company, a certification to that effect; or (C) if such Certificated Notes are being transferred pursuant to an exemption from registration, (i) a certification to that effect (in the form set forth in Exhibits B-1 and B-2, if applicable) and (ii) if the Company or Registrar so requests, an opinion of counsel or other evidence reasonably satisfactory to them as to the compliance with the restrictions set forth in the Legend. 19 (iv) Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below. Upon receipt by the Trustee of a Certificated Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with: (A) so long as the Notes are Restricted Notes, certification, in the form set forth in Exhibit B-1, that such Certificated Note is being transferred to a Qualified Institutional Buyer in accordance with Rule 144A; and (B) written instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Note and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the Certificated Note to be exchanged, and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the Certificated Note so cancelled. If no Global Notes are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of an Officers' Certificate, a new Global Note in the appropriate principal amount. (b) Subject to the succeeding paragraph, every Note shall be subject to the restrictions on transfer provided in the Legend including the delivery of an opinion of counsel, if so provided. Whenever any Restricted Note is presented or surrendered for registration of transfer or for exchange for a Note registered in a name other than that of the Holder, such Note must be accompanied by a certificate in substantially the form set forth in Exhibit B-1, dated the date of such surrender and signed by the Holder of such Note, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Note not so accompanied by a properly completed certificate. (c) The restrictions imposed by the Legend upon the transferability of any Note shall cease and terminate when such Note has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Note as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Note for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable 20 to the Company, addressed to the Company and in form acceptable to the Company, to the effect that the transfer of such Note has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Note, of like tenor and aggregate principal amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement registering the Notes under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned opinion of counsel or registration statement. (d) As used in the preceding two paragraphs of this Section 2.12, the term "transfer" encompasses any sale, pledge, transfer, hypothecation or other disposition of any Note. (e) The provisions below shall apply only to Global Notes: (1) Notwithstanding any other provisions of this Indenture or the Notes, except as provided in Section 2.12(a)(ii), a Global Note shall not be exchanged in whole or in part for a Note registered in the name of any Person other than the Depositary or one or more nominees thereof, provided that a Global Note may be exchanged for Notes registered in the names of any person designated by the Depositary in the event that (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note or such Depositary has ceased to be a "clearing agency" registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days or (ii) an Event of Default has occurred and is continuing with respect to the Notes. Any Global Note exchanged pursuant to clause (i) above shall be so exchanged in whole and not in part, and any Global Note exchanged pursuant to clause (ii) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note. (2) Notes issued in exchange for a Global Note or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Note issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. (3) Subject to the provisions of clause (5) below, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members (as defined 21 below) 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 Notes. (4) In the event of the occurrence of any of the events specified in clause (1) above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Notes in definitive, fully registered form, without interest coupons. (5) Neither any members of, or participants in, the Depositary (collectively, the "Agent Members") nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note. (6) Each Holder of a Note agrees to indemnify the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder's Note in violation of any provision of this Indenture and/or applicable United States Federal or state securities law. (7) The Trustee shall have no responsibility or obligation to any beneficial owner of an interest in a Global Note, a member of, or a participant in, DTC or other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member, beneficial owner or other Person (other than DTC) of any notice or the payment of any amount under or with respect to such Notes. (8) 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 Note (including any transfers between or among Agent Members or beneficial owners of interests in any Global Note) 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. SECTION 2.13 CUSIP Numbers. The Company in issuing the Notes may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption 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 22 on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP numbers. SECTION 2.14 Defaulted Interest. If the Company defaults in a payment of interest on the Notes, it shall pay, or shall deposit with the Paying Agent, money in immediately available funds sufficient to pay, the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date. A special record date, as used in this Section 2.14 with respect to the payment of any defaulted interest, shall mean the 15th day next preceding the date fixed by the Company for the payment of defaulted interest, whether or not such day is a Business Day. At least 15 days before the subsequent special record date, the Company shall mail to each Holder and to the Trustee a notice that states the subsequent special record date, the payment date and the amount of defaulted interest to be paid. ARTICLE 3 REDEMPTION AND PURCHASES SECTION 3.01 Optional Redemption. The Notes are not redeemable prior to February 14, 2008. On and after February 14, 2008, the Company may, at its option, redeem the Notes for cash, in whole at any time or in part from time to time, on any date prior to maturity, upon notice as set forth in Section 3.04, at the following prices (expressed in percentages of the principal amount) (the "Redemption Price"), together with accrued and unpaid interest to, but excluding, the date fixed for redemption (the "Redemption Date"), subject to the right of Holders of record on the immediately preceding Regular Record Date to receive the interest due on the succeeding Interest Payment Date. During the twelve months commencing February 14 of the years set forth below: Year Redemption Price ---- ---------------- 2008................................................. 102.1% 2009................................................. 101.0% SECTION 3.02 Notice to Trustee. If the Company elects to redeem Notes pursuant to Section 3.01 hereof, it shall notify the Trustee at least 30 days prior but not more than 60 days prior to the Redemption Date of such intended Redemption Date, the principal amount of Notes to be redeemed and the CUSIP numbers of the Notes to be redeemed. SECTION 3.03 Selection of Notes to be Redeemed. If fewer than all the Notes are to be redeemed, the Trustee shall select the particular Notes to be redeemed from the outstanding Notes on a pro rata basis or by lot or in accordance with any other method of Trustee considers fair and appropriate. Notes and portions thereof that the Trustee selects shall be in principal amounts equal to $1,000 or any integral multiple thereof. 23 If any Note selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Note so selected, the converted portion of such Note shall be deemed to be first taken from the portion selected for redemption (provided, however, that the Holder of such Note so converted and deemed redeemed shall not be entitled to any additional interest payment as a result of such deemed redemption than such Holder would have otherwise been entitled to receive upon conversion of such Note). Notes which have been converted during a selection of Notes to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. The Trustee shall promptly notify the Company and the Registrar (if other than the Trustee) in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Notes shall relate, in the case of any Notes redeemed or to be redeemed only in part, to the portion of the principal amount of such Notes which has been or is to be redeemed. SECTION 3.04 Notice of Redemption. Notice of redemption shall be given in the manner provided in Section 13.02 hereof to the Holders of Notes to be redeemed. Such notice shall be given not less than 30 nor more than 60 days prior to the Redemption Date for redemption pursuant to Section 3.01. All notices of redemption shall state: (1) the Redemption Date; (2) the Redemption Price and interest accrued and unpaid to the Redemption Date, if any; (3) if fewer than all the outstanding Notes are to be redeemed, the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes which will be outstanding after such partial redemption; (4) that on the Redemption Date the Redemption Price and interest accrued and unpaid to the Redemption Date, if any, will become due and payable upon each such Note to be redeemed, and that (unless the Company defaults in making payment of the Redemption Price) interest thereon shall cease to accrue on and after such date; (5) the Conversion Rate, the date on which the right to convert the principal of the Notes to be redeemed will terminate and the places where such Notes may be surrendered for conversion; (6) in the event that the Shareholder Approval Condition shall have been satisfied, the election of the Company (which, subject to the provisions of Article 10 of this Indenture, shall be irrevocable) to pay the Cash Payment Component or to deliver shares of Common Stock in lieu of such Cash Payment Component with respect to any 24 Note (or portion thereof) that may be exchanged after mailing of such notice prior to the Redemption Date; (7) the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued and unpaid interest, if any; and (8) the CUSIP number of the Notes. The notice given shall specify the last date, if any be applicable, on which exchanges or transfers of Notes may be made pursuant to Section 2.06 hereof. Notice of redemption of Notes to be redeemed at the election of the Company shall be given by the Company. SECTION 3.05 Effect of Notice of Redemption. Notice of redemption having been given as provided in Section 3.04 hereof, the Notes so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued and unpaid interest) such Notes shall cease to bear interest. Upon surrender of any such Note for redemption in accordance with such notice, such Note shall be paid by the Company at the Redemption Price plus accrued and unpaid interest, if any; provided, however, that the installments of interest on Notes whose Stated Maturity is prior to or on the Redemption Date shall be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such on the relevant Record Date according to their terms and the provisions of Section 2.01 hereof. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid, bear interest from the Redemption Date at the Interest Rate. SECTION 3.06 Deposit of Redemption Price. Prior to 10:00 a.m. (New York City time) on any Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money (in immediately available funds) sufficient to pay the Redemption Price of all the Notes to be redeemed on that Redemption Date, other than any Notes called for redemption on that date which have been converted prior to the date of such deposit, and accrued and unpaid interest, if any, on such Notes. If any Note called for redemption is converted, any money deposited with the Trustee or with the Paying Agent or so segregated and held in trust for the redemption of such Note shall (subject to any right of the Holder of such Note or any Predecessor Note to receive interest as provided in Section 4.01 hereof) be paid to the Company on a Company Request or, if then held by the Company, shall be discharged from such trust. SECTION 3.07 Notes Redeemed in Part. Any Note which is to be redeemed only in part shall be surrendered at an office or agency of the Company designated for that purpose pursuant to Section 4.05 hereof (with, if the Company or the Trustee so requires, 25 due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or the Holder's attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered. SECTION 3.08 Conversion Arrangement on Call for Redemption. In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes called for redemption by an agreement with one or more investment banks or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, at or prior to 10:00 a.m. New York City time on the Redemption Date, an amount that, together with any amounts deposited with the Trustee by the Company for the redemption of such Notes, is not less than the Redemption Price of such Notes. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the Redemption Price of such Notes shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, any Notes not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 10) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Redemption Date, subject to payment of the above amount as aforesaid. The Trustee shall hold and pay to the Holders whose Notes are selected for redemption any such amount paid to it for purchase and conversion in the same manner as it would moneys deposited with it by the Company for the redemption of Notes. Without the Trustee's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Notes between the Company and such purchasers, including the costs and expenses incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture with respect to such arrangement for the purchase and conversion of any Notes. SECTION 3.09 Repurchase of Notes at Option of the Holder upon Change of Control. (a) If there shall have occurred a Change of Control, all or any portion of the Notes of any Holder equal to $1,000 or an integral multiple of $1,000, not previously called for redemption, shall be repurchased by the Company, at the option of such Holder, at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, together with interest accrued and unpaid to, but excluding, the repurchase date (the "Change of Control Repurchase Price"), on the date (the "Change of Control Repurchase Date") that is 30 days after the Change of Control Repurchase Notice; provided, however, that installments of interest on Notes whose Stated Maturity is prior to or on the Change of Control Repurchase Date shall be payable to the Holders of such Notes, or one or more predecessor Notes, registered as such on the relevant Regular Record Date according to their terms. Such right to require the repurchase of the Notes shall not continue after a discharge of the Company from its obligations with respect 26 to the Notes in accordance with Article 8, unless a Change of Control shall have occurred prior to such discharge. Whenever in this Indenture (including without limitation Sections 2.01, 6.01(a) and 6.07 hereof) or Exhibits A-1 and A-2 annexed hereto there is a reference, in any context, to the principal of any Note as of any time, such reference shall be deemed to include reference to the Change of Control Repurchase Price payable in respect to such Note to the extent that such Change of Control Repurchase Price is, was or would be so payable at such time, and express mention of the Change of Control Repurchase Price in any provision of this Indenture shall not be construed as excluding the Change of Control Repurchase Price in those provisions of this Indenture when such express mention is not made. A "Change of Control" of the Company shall be deemed to have occurred at such time as any of the following events shall occur: (i) the acquisition by any person, including any syndicate or group deemed to be a "person" under Section 13(d)(3) of the Exchange Act, of beneficial ownership, directly or indirectly (determined in accordance with Rule 13d-3 under the Exchange Act), through a purchase, merger or other acquisition transaction or series of transactions of shares of the Capital Stock of the Company entitling that person to exercise 50% or more of the total voting power of all shares of Capital Stock entitled to vote generally in elections of directors, other than any acquisition by the Company, any of its Subsidiaries or any of its employee benefit plans; (ii) any consolidation or merger of the Company with or into any other person, any merger of another person into the Company, or any conveyance, transfer, sale, lease or other disposition of all or substantially all of the Company's properties and assets to another person, other than: (1) any transaction (A) that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of the Company's Capital Stock and (B) pursuant to which holders of the Company's Capital Stock immediately prior to the transaction are entitled to exercise, directly or indirectly, 50% or more of the total voting power of all shares of the Company's Capital Stock entitled to vote generally in the election of directors of the continuing or surviving person immediately after the transaction; or (2) any merger solely for the purpose of changing the Company's jurisdiction of incorporation and resulting in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of Common Stock of the surviving entity; (iii) during any consecutive two-year period, individuals who at the beginning of that two-year period constituted the Company's board of directors (together with any new directors whose election to such board of directors, or whose nomination for election by the Company's stockholders, was approved by a vote of a majority of the directors then still in office who were either directors at the beginning of such period or whose 27 election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Company's board of directors then in office; or (iv) the Company is liquidated or dissolved or the Company's stockholders pass a special resolution approving a plan of liquidation or dissolution and no additional approvals of the Company's stockholders are required under applicable law to cause a liquidation or dissolution. (b) Unless the Company shall have theretofore called for redemption all of the outstanding Notes, prior to or on the 30th day after the occurrence of a Change of Control, the Company, or, at the written request and expense of the Company, the Trustee, shall give to all Noteholders, in the manner provided in Section 13.02 hereof, notice of the occurrence of the Change of Control and of the repurchase right set forth herein arising as a result thereof. If the Trustee is requested to give such notice the Company will provide the written request at least one Business Day prior. The Company shall also deliver a copy of such notice of a repurchase right to the Trustee. The notice shall include a form of Change of Control Repurchase Notice (as defined in Section 3.9(c)) to be completed by the Noteholder and shall state: (1) briefly, the events causing a Change of Control and the date of such Change of Control; (2) the date by which the Change of Control Repurchase Notice pursuant to this Section 3.09 must be given; (3) the Change of Control Repurchase Date; (4) the Change of Control Repurchase Price; (5) the name and address of the Paying Agent and the Conversion Agent; (6) the Conversion Rate and any adjustments thereto; (7) that Notes as to which a Change of Control Repurchase Notice has been given may be converted pursuant to Article 10 hereof only if the Change of Control Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; (8) that Notes must be surrendered to the Paying Agent to collect payment of the Change of Control Repurchase Price; (9) that the Change of Control Repurchase Price for any Note as to which a Change of Control Repurchase Notice has been duly given and not withdrawn will be paid promptly following the later of the Change of Control Repurchase Date and the time of surrender of such Note as described in (8) above; (10) briefly, the procedures the Holder must follow to exercise rights under this Section 3.09; (11) briefly, the conversion rights of the Notes; 28 (12) the procedures for withdrawing a Change of Control Repurchase Notice; (13) that, unless the Company defaults in making payment of such Change in Control Repurchase Price, interest on Notes surrendered for repurchase will cease to accrue on and after the Change of Control Repurchase Date; and (14) the CUSIP number of the Notes. (c) A Holder may exercise its rights specified in Section 3.09(a) hereof upon delivery of a written notice of purchase (a "Change of Control Repurchase Notice") to the Paying Agent at any time prior to the close of business on the Change of Control Repurchase Date, stating: (1) the certificate number of the Note which the Holder will deliver to be purchased (unless such Note is held in book-entry form); (2) the portion of the principal amount of the Note which the Holder will deliver to be purchased, which portion must be $1,000 or an integral multiple thereof; and (3) that such Note shall be purchased pursuant to the terms and conditions specified in paragraph 7 of the Notes. The delivery of such Note to the Paying Agent prior to, on or after the Change of Control Repurchase Date (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Change of Control Repurchase Price therefor; provided, however, that such Change of Control Repurchase Price shall be so paid pursuant to this Section 3.09 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Change of Control Repurchase Notice. The Company shall purchase from the Holder thereof, pursuant to this Section 3.09, a portion of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note. Any purchase by the Company contemplated pursuant to the provisions of this Section 3.09 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Change of Control Repurchase Date and the time of delivery of the Note to the Paying Agent in accordance with this Section 3.09. Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Change of Control Repurchase Notice contemplated by this Section 3.09(c) shall have the right to withdraw such Change of Control Repurchase Notice at any time prior to the close of business on the Change of Control Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.10. The Paying Agent shall promptly notify the Company of the receipt by it of any Change of Control Repurchase Notice or written withdrawal thereof. 29 SECTION 3.10 Effect of Change of Control Repurchase Notice. Upon receipt by the Paying Agent of the Change of Control Repurchase Notice specified in Section 3.09(c), the Holder of the Note in respect of which such Change of Control Repurchase Notice was given shall (unless such Change of Control Repurchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Change of Control Repurchase Price with respect to such Note. Such Change of Control Repurchase Price shall be paid to such Holder, subject to receipts of funds and/or Notes by the Paying Agent, promptly following the later of (x) the Change of Control Repurchase Date with respect to such Note (provided the conditions in Section 3.09(c) have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.09(c). Notes in respect of which a Change of Control Repurchase Notice, has been given by the Holder thereof may not be converted pursuant to Article 10 hereof on or after the date of the delivery of such Change of Control Repurchase Notice unless such Change of Control Repurchase Notice has first been validly withdrawn as specified in the following two paragraphs. A Change of Control Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Change of Control Repurchase Notice at any time prior to the close of business on the Change of Control Repurchase Date specifying: (1) the certificate number of the Note in respect of which such notice of withdrawal is being submitted (or such other information as is necessary to identify the holder, with respect to a book-entry transfer), (2) the principal amount of the Note with respect to which such notice of withdrawal is being submitted, and (3) the principal amount, if any, of such Note which remains subject to the original Change of Control Repurchase Notice and which has been or will be delivered for purchase by the Company. There shall be no repurchase of any Notes pursuant to Section 3.09 if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such Notes, of the required Change of Control Repurchase Notice) and is continuing an Event of Default (other than a default in the payment of the Change of Control Repurchase Price with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes (x) with respect to which a Change of Control Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Change of Control Repurchase Price with respect to such Notes) in which case, upon such return, the Change of Control Repurchase Notice with respect thereto shall be deemed to have been withdrawn. SECTION 3.11 Deposit of Change of Control Repurchase Price. Prior to 10:00 a.m. (New York City time) on the Business Day following the Change of Control Repurchase Date, the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money (in immediately 30 available funds if deposited on such Business Day) sufficient to pay the aggregate Change of Control Repurchase Price of all the Notes or portions thereof which are to be purchased as of the Change of Control Repurchase Date. SECTION 3.12 Notes Purchased in Part. Any Note which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered which is not purchased. SECTION 3.13 Covenant to Comply with Securities Laws upon Purchase of Notes. In connection with any offer to purchase or repurchase Notes under Section 3.09 hereof (provided that such offer or purchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable, (ii) file the related Schedule 13E-3 (or any successor schedule, form or report) or any other schedule required under the Exchange Act, and (iii) otherwise comply with all federal and state securities laws so as to permit the rights and obligations under Section 3.09 to be exercised in the time and in the manner specified in Section 3.09. SECTION 3.14 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed as provided in paragraph 13 of the Notes, together with interest, if any, thereon, held by them for the payment of the Change of Control Repurchase Price; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.11 exceeds the aggregate Change of Control Repurchase Price of the Notes or portions thereof which the Company is obligated to purchase as of the Change of Control Repurchase Date then promptly after the Business Day following the Change of Control Repurchase Date the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon. ARTICLE 4 COVENANTS SECTION 4.01 Payment of Principal, Premium, Interest on the Notes.

Principal amount, Redemption Price, Change of Control Repurchase Price, and cash interest shall be considered paid on the applicable date due if on such date (or, in the case of a Change of Control Repurchase Price on the Business Day following the applicable 31 Change of Control Repurchase Date) the Trustee or the Paying Agent holds, in accordance with this Indenture, money or Notes, if permitted hereunder, sufficient to pay all such amounts then due. The Company shall, to the extent permitted by law, pay cash interest on overdue amounts at the rate per annum set forth in paragraph 1 of the Notes, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. SECTION 4.02 SEC and Other Reports. The Company shall file with the Trustee, within 15 days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act. Such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. 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 with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers' Certificate). SECTION 4.03 Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2003) an Officer's Certificate, stating whether or not to the best knowledge of the signer thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. SECTION 4.05 Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, the City of New York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer, exchange, purchase, redemption or conversion and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The principal corporate trust office of The Bank of New York, located at 101 Barclay Street, 8W, New York, NY 10286, attention: Corporate Trust Division, shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If 32 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 address of the Trustee set forth in Section 13.02. The Company may also from time to time designate one or more other offices or agencies where the Notes 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. SECTION 4.06 Delivery of Certain Information. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a holder or any beneficial holder of Notes or shares of Common Stock issued upon conversion thereof, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder or any beneficial holder of Notes or holder of shares of Common Stock issued upon conversion of Notes, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. "Rule 144A Information" shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act. SECTION 4.07 Additional Interest Notice. In the event the Company is required to pay amounts pursuant to the terms hereof, the Company shall provide a notice (an "Additional Interest Payment Notice") to the Trustee of its obligation to pay an Additional Interest Amount no later than fifteen days prior to the payment date for the Additional Interest Amount, and the Additional Interest Payment Notice shall set forth the dividend per share of Common Stock payable by the Company on the Common Stock on the related record date, the related dividend payment date, the aggregate amount of Additional Interest Amounts to be paid and the amount of Additional Interest Amount to be paid for each $1,000 principal amount of Notes by the Company on such payment date. The Trustee shall not at any time be under a duty or owe a responsibility to any holder of the Notes to determine the amount of the Additional Interest Amount, or with respect to the nature, extent or calculation of the amount of Additional Interest Amounts when made, or with respect to the method employed in such calculation of the Additional Interest Amounts. ARTICLE 5 MERGERS AND SALES OF ASSETS SECTION 5.01 When Company May Merge or Transfer Assets. The Company shall not consolidate with, merge with or into any other person or convey, transfer or lease its properties and assets substantially as an entirety to any person, unless: (a) either (1) the Company shall be the continuing corporation or (2) the person (if other than the Company) formed by such consolidation or into which the Company is merged or the person which acquires by conveyance, transfer or lease the properties and assets of the Company substantially as an entirety (i) shall be organized and validly existing under the laws of 33 the United States or any State thereof or the District of Columbia and (ii) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, all of the obligations of the Company under the Notes and this Indenture; (b) at the time of such transaction, no Event of Default and no event which, after notice or lapse of time, would become an Event of Default, shall have happened and be continuing; and (c) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this Article 5 and that all conditions precedent herein provided for relating to such transaction have been satisfied. For purposes of the foregoing, the transfer (by assignment, sale or otherwise) of the properties and assets of one or more Subsidiaries (other than to the Company or another Subsidiary), which, if such assets were owned by the Company, would constitute all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. The successor person formed by such consolidation or into which the Company is merged or the successor person to which such conveyance or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of obligations the Company may have under a supplemental indenture pursuant to Section 10.11, the Company shall be discharged from all obligations and covenants under this Indenture and the Notes. Subject to Section 9.06, the Company, the Trustee and the successor person shall enter into a supplemental indenture to evidence the succession and substitution of such successor person and such discharge and release of the Company. ARTICLE 6 DEFAULTS AND REMEDIES SECTION 6.01 Events of Default. An "Event of Default" occurs if: (1) the Company fails to pay when due the principal of or premium, if any, on any of the Notes at maturity, upon redemption or exercise of a repurchase right or otherwise; (2) the Company fails to pay an installment of interest (including Liquidated Damages Amounts and Additional Interest Amounts, if any) on any of the Notes that continues for 30 days after the date when due, provided that a failure to make or provide for the payment of any of the first five scheduled interest payments on the Notes within three Business Days after an Interest Payment Date will constitute an Event of Default with no additional grace or cure period; 34 (3) the Company fails to (A) deliver shares of Common Stock, together with cash in lieu of fractional shares, when such Common Stock or cash in lieu of fractional shares is required to be delivered upon conversion of a Note, or (B) make payment of the Cash Payment Component when such cash is required to be delivered upon conversion of a Note, and, in each case, that failure continues for 10 days after the relevant delivery date; (4) the Company fails to perform or observe any other term, covenant or agreement contained in the Notes or this Indenture for a period of 60 days after receipt by the Company of a Notice of Default (as defined in this Section 6.01); (5) (A) the Company or any Significant Subsidiary fails to pay at maturity (after giving effect to any applicable grace period) any Indebtedness in an aggregate principal amount in excess of $10 million or (B) any of the Company's Indebtedness, or Indebtedness of any Significant Subsidiary, aggregating $10 million or more shall have been accelerated and declared due and payable prior to the scheduled maturity thereof, and such acceleration is not rescinded or annulled within a 30-day period after the date of such acceleration; (6) the Company or any Significant Subsidiary pursuant to or under or within the meaning of any Bankruptcy Law: (A) commences a voluntary case or proceeding; (B) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it; (C) consents to the appointment of a Custodian of it or for any substantial part of its property; (D) makes a general assignment for the benefit of its creditors; (E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or (F) consents to the filing of such a petition or the appointment of or taking possession by a Custodian; and (7) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company or any Significant Subsidiary in an involuntary case or proceeding, or adjudicates the Company or any Significant Subsidiary insolvent or bankrupt; (B) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its or their properties; or 35 (C) orders the winding up or liquidation of the Company or any Significant Subsidiary; and the order or decree remains unstayed and in effect for 60 days. "Bankruptcy Law" means Title 11, United States Code, or any similar federal or state law for the relief of debtors. "Custodian" means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. (8) the Pledge Agreement shall cease to be in full force and effect or enforceable in accordance with its terms, prior to the termination thereof in accordance with Section 18 of the Pledge Agreement. A Default under clause (4) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (4) above after actual receipt of such notice. Any such notice must specify the Default, demand that it be remedied and state that such notice is a "Notice of Default". The Company will deliver to the Trustee, within five Business Days of becoming aware of the occurrence of an Event of Default, written notice thereof. In addition, the Company shall deliver to the Trustee, within 30 days after it becomes aware of the occurrence thereof, written notice of any event which with the lapse of time would become an Event of Default under clause (4) above, its status and what action the Company is taking or proposes to take with respect thereto. SECTION 6.02 Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(6) or (7)) occurs and is continuing, the Trustee by Notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding by notice to the Company and the Trustee, may declare the notes due and payable at their principal amount together with accrued and unpaid interest. Upon a declaration of acceleration, such principal and accrued and unpaid interest to the date of payment shall be immediately due and payable. If an Event of Default specified in Section 6.01(6) or (7) above occurs and is continuing, then the principal and the interest on all the Notes shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Noteholders. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by notice to the Trustee (and without notice to any other Noteholder) may rescind or annul an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal and any accrued cash interest that have become due solely as a result of acceleration 36 and if all amounts due to the Trustee under Section 7.06 have been paid. No such rescission shall affect any subsequent Default or impair any right consequent thereto. SECTION 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of the principal, the premium, if any, and any accrued cash interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if the Trustee does not possess any of the Notes or produce any of the Notes in the proceeding. A delay or omission by the Trustee or any Noteholder 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. SECTION 6.04 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding, by notice to the Trustee (and without notice to any other Noteholder), may waive an existing Default and its consequences except (a) an Event of Default described in Section 6.01(1) or (2), (b) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Noteholder affected or (c) a Default which consists of a failure to convert any Note in accordance with the terms of Article 10. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right. This Section 6.04 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA. SECTION 6.05 Control by Majority. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Noteholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it against loss, liability or expense. This Section 6.05 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA. SECTION 6.06 Limitation on Suits. A Noteholder may not pursue any remedy with respect to this Indenture or the Notes unless: (1) the Holder gives to the Trustee written notice stating that an Event of Default is continuing; (2) the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer to the Trustee reasonable indemnity satisfactory to the Trustee against any loss, liability or expense; 37 (4) the Trustee does not comply with the request within 60 days after receipt of such notice, request and offer of indemnity; and (5) the Holders of a majority in aggregate principal amount of the Notes at the time outstanding do not give the Trustee a direction inconsistent with the request during such 60-day period. A Noteholder may not use this Indenture to prejudice the rights of any other Noteholder or to obtain a preference or priority over any other Noteholder. SECTION 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, premium, if any, plus Redemption Price, Change of Control Repurchase Price or any accrued cash interest (including Additional Interest Amounts, if any) in respect of the Notes held by such Holder, on or after the respective due dates expressed in the Notes or any Redemption Date, and to convert the Notes in accordance with Article 10, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected adversely without the consent of such Holder. SECTION 6.08 Collection Suit by Trustee. If an Event of Default described in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount owing with respect to the Notes and the amounts provided for in Section 7.06. SECTION 6.09 Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Notes or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount, Redemption Price, Change of Control Repurchase Price or any accrued cash interest in respect of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise, (a) to file and prove a claim for the whole amount of the principal amount, Redemption Price, Change of Control Repurchase Price or any accrued cash interest (including, without limitation, Additional Interest Amounts) and to file such 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 or any other amounts due the Trustee under Section 7.06) and of the Holders allowed in such judicial proceeding, and (b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding 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 38 payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10 Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order: (1) to the Trustee for amounts due under Section 7.06; (2) to Noteholders for amounts due and unpaid on the Notes for the principal amount, Redemption Price, Change of Control Purchase Price or any accrued cash interest (including Additional Interest Amounts, if any) as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Notes; and (3) the balance, if any, to the Company. The Trustee may fix a record date and payment date for any payment to Noteholders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Noteholder and the Company a notice that states the record date, the payment date and the amount to be paid. SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Notes at the time outstanding. This Section 6.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. SECTION 6.12 Waiver of Stay, Extension or Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount, Redemption Price, Change of Control Repurchase Price or any accrued cash interest (including Additional Interest Amounts, if any) in respect of Notes, or any interest on such amounts, as contemplated herein, or which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives 39 all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. ARTICLE 7 TRUSTEE SECTION 7.01 Duties and Responsibilities of the Trustee; During Default; Prior to Default. (a) The Trustee, prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all such Events of Default which may have occurred, (1) undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (2) in the absence of bad faith on its part, 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; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture. In case an Event of Default hereunder has occurred (which has not been cured or waived), 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. No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that (b) prior to the occurrence of an Event of Default hereunder and after the curing or waiving of all such Events of Default which may have occurred: (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any statements, certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such statements, certificates or opinions which by any provision 40 hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; (c) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (d) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders pursuant to Section 6.05 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture. None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers. The provisions of this Section 7.01 are in furtherance of and subject to Sections 315 and 316 of the TIA. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 7.01. SECTION 7.02 Certain Rights of the Trustee. In furtherance of and subject to the TIA and subject to Section 7.01: (a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, Officers' Certificate or any other certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon, Note or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; (b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers' Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by a copy thereof certified by the secretary or an assistant secretary of the Company; (c) the Trustee may consult with counsel of its selection and any advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in reliance thereon; (d) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Indenture at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the 41 costs, expenses and liabilities which might be incurred by it in compliance with such request, order or direction; (e) the Trustee shall not be liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion, rights or powers conferred upon it by this Indenture; (f) 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, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; and (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder; (h) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence by herein specifically prescribed) may, in the absence of bad faith on its part, conclusively rely upon an Officers' Certificate; (i) the Trustee shall not be deemed to have or be charged with knowledge of any Default or Event of Default unless a Responsible Officer of the Trustee has received at the Corporate Trust Office of the Trustee written notice of such Default or Event of Default, as the case may be, from the Company or any Holder of the Notes, and such notice references the Notes and this Indenture; (j) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder; (k) the Trustee may request that the Company deliver an Officers' Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers' Certificate may be signed by any person authorized to sign an Officers' Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded; (l) the permissive right of the Trustee to take action under this Indenture shall not be construed as a duty. 42 SECTION 7.03 Trustee Not Responsible for Recitals, Disposition of Notes or Application of Proceeds Thereof. The recitals contained herein and in the Notes, except the Trustee's certificates of authentication, shall be taken as the statements of the Company, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable for the use or application by the Company of any of the Notes or of the proceeds thereof. SECTION 7.04 Trustee and Agents May Hold Notes; Collections, etc. The Trustee or any agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee or such agent and, subject to Sections 7.07 and 7.12, if operative, may otherwise deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee or such agent. SECTION 7.05 Moneys Held by Trustee. All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law. Neither the Trustee nor any agent of the Company or the Trustee shall be under any liability for interest on any moneys received by it hereunder except as may otherwise be agreed in writing with the Company. SECTION 7.06 Compensation and Indemnification of Trustee and Its Prior Claim. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) to be agreed to in writing by the Trustee and the Company, and the Company covenants and agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by or on behalf of it in accordance with any of the provisions of this Indenture (including (i) the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ and (ii) interest at the prime rate on any disbursements and advances made by the Trustee and not paid by the Company within 5 days after receipt of an invoice for such disbursement or advance) except any such expense, disbursement or advance as may arise from its negligence or willful misconduct. The Company also covenants to indemnify the Trustee and each predecessor Trustee for, and to hold them harmless against, any loss, liability or expense incurred without negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in connection with the exercise or performance of any of its powers or duties hereunder. The obligations of the Company under this Section 7.06 to compensate and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each predecessor Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture, the resignation or removal of the Trustee and the termination of the Indenture. Such additional indebtedness shall be a senior claim to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders of particular Notes, and the Notes are hereby effectively subordinated to 43 such senior claim to such extent. The provisions of this Section 7.06 shall survive the satisfaction and discharge of this Indenture, the resignation or removal of the Trustee and the termination, for any reason, of this Indenture. When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01 or in connection with Article 6 hereof, the expenses (including the reasonable fees and expenses of its counsel) and the compensation for services in connection therewith are to constitute expenses of administration under any Bankruptcy Law. SECTION 7.07 Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA. For purposes of Section 310(b)(1) of the Trust Indenture Act and to the extent permitted thereby, the Trustee shall not be deemed to have a conflicting interest arising from its capacity as trustee in respect of any series of securities issued under the Indenture, dated as May 1, 2000, by and between the Company and The Bank of New York, as trustee, or any securities issued under or in connection with the Purchase Contract Agreement dated as of November 16, 2001, between the Company and The Bank of New York, as purchase contract agent. SECTION 7.08 Persons Eligible for Appointment as Trustee. The Trustee shall at all times be a corporation or banking association having a combined capital and surplus of at least $50,000,000. If such corporation or banking association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then, for the purposes of this Section 7.08, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.08, the Trustee shall resign immediately in the manner and with the effect specified in Section 7.09. SECTION 7.09 Resignation and Removal; Appointment of Successor Trustee. (a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign with respect to one or more or all series of Notes by giving written notice of resignation to the Company and by mailing notice thereof by first class mail to the Holders of Notes at their last addresses as they shall appear on the Note register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee or trustees by written instrument in duplicate, executed by authority of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee or trustees. If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning trustee may petition any court of competent jurisdiction for the appointment of a successor trustee, or any Noteholder who has been a bona fide Holder of a Note for at least six months may, subject to the provisions of Section 7.10, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee. (b) In case at any time any of the following shall occur: 44 (i) the Trustee shall fail to comply with the provisions of Section 7.07 with respect to any Notes after written request therefor by the Company or by any Noteholder who has been a bona fide Holder of a Note for at least six months; or (ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.08 and shall fail to resign after written request therefor by the Company or by any Noteholder; or (iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation; then, in any such case, the Company may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors of the Company, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 7.10, any Noteholder who has been a bona fide Holder of a Note for at least six months may on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee. If no successor trustee shall have been appointed and have accepted appointment within 30 days after a notice of removal has been given, the removed trustee may, at the cost and expense of the Company, petition a court of competent jurisdiction for the appointment of a successor trustee. (c) The Holders of a majority in aggregate principal amount of the Notes at the time outstanding may at any time remove the Trustee and appoint a successor trustee by delivering to the Trustee so removed, to the successor trustee so appointed and to the Company the evidence provided for in Section 1.05 of the action in that regard taken by the Noteholders. (d) Any resignation or removal of the Trustee and any appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10. SECTION 7.10 Acceptance of Appointment by Successor Trustee. Any successor trustee appointed as provided in Section 7.09 shall execute and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee hereunder; but, nevertheless, on the written request of the Company or of the successor trustee, upon payment of its charges then unpaid, the trustee ceasing to act shall pay over to the successor trustee all moneys at the time held by it hereunder and shall execute and deliver an instrument transferring to such 45 successor trustee all such rights, powers, duties and obligations. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. Any trustee ceasing to act shall, nevertheless, retain a prior claim pursuant to Section 7.06 upon all property or funds held or collected by such trustee to secure any amounts then due it pursuant to the provisions of Section 7.06. No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be qualified under the provisions of Section 7.07 and eligible under the provisions of Section 7.08. Upon acceptance of appointment by any successor trustee as provided in this Section 7.10, the Company shall mail notice thereof by first class mail to the Holders of Notes at their last addresses as they shall appear in the register. If the acceptance of appointment is substantially contemporaneous with the resignation, then the notice called for by the preceding sentence may be combined with the notice called for by Section 7.09. If the Company fails to mail such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Company. SECTION 7.11 Merger, Conversion, Consolidation or Succession to Business of Trustee. Any corporation or banking association into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or banking association resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or banking association succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation or banking association shall be qualified under the provisions of Section 7.07 and eligible under the provisions of Section 7.08, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver such Notes so authenticated; and, in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificate shall have the full force and effect that this Indenture provides for the certificate of authentication of the Trustee; provided, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation. SECTION 7.12 Preferential Collection of Claims Against the Company. The Trustee shall comply with the provisions of Section 311 of the TIA. SECTION 7.13 Reports by the Trustee. (a) The Trustee shall transmit to Holders and other persons such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the TIA on or before July 15 in each year that such report is required, such reports to be dated as of the immediately preceding May 15. (b) A copy of each such report shall, at the time of such transmission to Noteholders, be furnished to the Company and be filed by the Trustee with each stock exchange 46 upon which the Notes are listed and also with the SEC. The Company agrees to notify promptly the Trustee when and as the Notes become admitted to trading on any national securities exchange and of any delisting thereof. SECTION 7.14 Trustee to Give Notice of Default, But May Withhold in Certain Circumstances. The Trustee shall transmit to the Noteholders, as the names and addresses of such Holders appear on the Note register, notice by mail of all Defaults known to the Trustee which have occurred, such notice to be transmitted within 90 days after the occurrence thereof, unless such defaults shall have been cured before the giving of such notice; provided that, except in the case of Default in the payment of the principal of, interest on, or other similar obligation with respect to, any of the Notes, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee, or a trust committee of directors or trustees and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the best interests of the Noteholders. ARTICLE 8 SATISFACTION AND DISCHARGE OF INDENTURE SECTION 8.01 Termination of the Company's Obligations. Except as otherwise provided in this Section 8.01 and in Section 8.05 hereof, the Company may terminate its obligations under the Notes and this Indenture if: (i) all Notes previously authenticated and delivered (other than destroyed, lost or stolen Notes that have been replaced or Notes that are paid pursuant to Section 2.07 hereof or Notes for whose payment money or securities have theretofore been held in trust and thereafter repaid to the Company, as provided in Section 8.03 hereof) have been delivered to the Trustee for cancellation and the Company has paid all sums payable by it hereunder; or (ii) (A) all of the Notes mature within one year or all of them are to be called for redemption within one year under arrangements satisfactory to the Trustee for giving the notice of redemption, (B) the Company deposits in trust with the Trustee during such one-year period, under the terms of an irrevocable trust agreement in form and substance satisfactory to the Trustee, as trust funds solely for the benefit of the Holders for that purpose, money or U.S. Government Obligations sufficient to pay principal, premium, if, any, and interest on the Notes to maturity or redemption, as the case may be, and to pay all other sums payable by it hereunder, (C) no Default or Event of Default with respect to the Notes shall have occurred and be continuing on the date of such deposit, (D) such deposit will not result in a breach or violation of, or constitute a default under, this Indenture or any other agreement or instrument to which the Company is a party or by which it is bound and (E) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, in each case stating that all conditions precedent provided for herein relating to the satisfaction and discharge of this Indenture have been complied with. 47 With respect to the foregoing clause (i), the Company's obligations under Section 7.06 hereof shall survive. With respect to the foregoing clause (ii), the Company's obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 4.01, 4.05, 7.06, 7.09 and 8.03 and in Article 10 of this Indenture shall survive until the Notes are no longer outstanding. Thereafter, only the Company's obligations in Sections 7.06 and 8.03 of this Indenture shall survive. After any such irrevocable deposit, the Trustee upon request shall acknowledge in writing the discharge of the Company's obligations, as the case may be, under the Notes and this Indenture, except for those surviving obligations specified above. SECTION 8.02 Application of Trust Money. The Trustee or Paying Agent shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 8.01 and shall apply the deposited money and the money from U.S. Government Obligations in accordance with the Notes and this Indenture to the payment of principal of, premium, if any, and interest on the Notes; but such money need not be segregated from other funds except to the extent required by law. SECTION 8.03 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with Section 8.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with Section 8.01; provided that, if the Company has made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent. SECTION 8.04 Repayment of the Company. The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Notes that remains unclaimed for two years, subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Noteholders with respect to such money or securities for that period commencing after the return thereof. SECTION 8.05 Conversion of Notes Upon Discharge. Notwithstanding any satisfaction or discharge of this Indenture pursuant to the provisions of this Article 8, for so long as any of the Notes are outstanding, the conversion right of Noteholders set forth in this Indenture shall not expire until the close of business on February 14, 2010 and the Company shall remain obligated to issue duly authorized, fully paid and nonassessable shares of Common Stock upon conversion of the Notes in accordance with the terms of this Indenture. 48 ARTICLE 9 AMENDMENTS SECTION 9.01 Without Consent of Holders. The Company and the Trustee may amend this Indenture or the Notes without the consent of any Noteholder for the purposes of, among other things: (1) adding to the Company's covenants or obligations under this Indenture for the benefit of the Holders; (2) surrendering any right, power or option conferred upon the Company by this Indenture; (3) providing for conversion rights of Holders if any reclassification or change of Common Stock or any consolidation, merger or sale of all or substantially all of the Company's assets occurs; (4) providing for the assumption of the Company's obligations to the Holders in the case of a merger, consolidation, conveyance, transfer or lease; (5) increasing the Conversion Rate, provided that the increase will not adversely affect the interests of Holders in any material respect; (6) complying with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; (7) making any changes or modifications to this Indenture necessary in connection with the registration of the Notes under the Securities Act as contemplated by the registration rights agreement, provided that this action does not adversely affect the interests of the Holders in any material respect; (8) curing any ambiguity or correcting or supplementing any defective provision contained in this Indenture; provided that such modification or amendment does not, in the good faith opinion of the Board of Directors, adversely affect the interests of the Holders in any material respect; (9) adding or modifying any other provisions which the Company may deem necessary or desirable and which will not adversely affect the interests of the Holders in any material respect; or (10) to evidence and provide for the acceptance of appointment of a successor Trustee. SECTION 9.02 With Consent of Holders. With the written consent of the Holders of at least a majority in aggregate principal amount of the Notes at the time outstanding, the Company and the Trustee may amend this Indenture or the Notes. However, without the consent of each Noteholder affected, an amendment to this Indenture or the Notes may not: 49 (1) change the maturity of the principal of or any installment of interest on any Note (including any payment of Liquidated Damages Amounts); (2) reduce the principal amount of, or any premium or interest on (including any payment of Liquidated Damages Amounts or Additional Interest Amounts), any Note; (3) change the currency of payment of such Note or interest thereon; (4) impair the right to institute suit for the enforcement of any payment on or with respect to any Note; (5) except as otherwise permitted or contemplated by provisions concerning corporate reorganizations, adversely affect the repurchase option of Holders upon a Change of Control or the conversion rights of Holders; (6) modify the provisions relating to the pledge of securities in Article 12 hereof, in a manner that adversely affects the interests of the Holders; or (7) reduce the percentage in aggregate principal amount of Notes outstanding necessary to modify or amend this Indenture or to waive any past default. It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof. After an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Persons entitled to consent to any indenture supplemental hereto. If a record date is fixed, the Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to consent to such supplemental indenture, whether or not such Holders remain Holders after such record date; provided, that unless such consent shall have become effective by virtue of the requisite percentage having been obtained prior to the date which is 90 days after such record date, any such consent previously given shall automatically and without further action by any Holder be cancelled and of no further effect. SECTION 9.03 Compliance with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall comply with the TIA. SECTION 9.04 Revocation and Effect of Consents, Waivers and Actions. Until an amendment, waiver or other action by Holders becomes effective, a consent thereto by a Holder of a Note hereunder is a continuing consent by the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same obligation as the consenting Holder's Note, even if notation of the consent, waiver or action is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder's Note or portion of the Note if the Trustee receives the notice of revocation before the date the 50 amendment, waiver or action becomes effective. After an amendment, waiver or action becomes effective, it shall bind every Noteholder. SECTION 9.05 Notation on or Exchange of Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Company as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion of the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Notes. SECTION 9.06 Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall be entitled to receive, and (subject to the provisions of Section 7.01) shall be fully protected in relying upon, an Officers' Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture. SECTION 9.07 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. ARTICLE 10 CONVERSION SECTION 10.01 Conversion Right and Conversion Rate. (a) The Notes will not be convertible prior to August 14, 2003. At any time on or after August 14, 2003, subject to and upon compliance with the provisions of this Article, at the option of the Holder thereof, any Note or any portion of the principal amount thereof which is $1,000 or an integral multiple of $1,000 may be converted at the principal amount thereof, or of such portion thereof, into a combination of cash and duly authorized, fully paid and nonassessable shares of Common Stock (or, in the event that the Shareholder Approval Condition shall have been satisfied and the Company so elects, entirely into shares of Common Stock) as provided in this Section 10.01. Such conversion right shall expire at the close of business on February 14, 2010. In case a Note or portion thereof is called for redemption, such conversion right in respect of the Note or the portion so called shall expire at the close of business on the Business Day immediately preceding the Redemption Date, unless the Company defaults in making the payment due upon redemption. A Note for which a Holder has delivered a Change of Control Repurchase Notice requiring the Company to repurchase the Note may be surrendered for conversion only if such notice is withdrawn in accordance with Section 3.10 hereof. 51 (b) Upon conversion of any Note or any portion of the principal amount thereof prior to the time the Shareholder Approval Condition has been satisfied, the Company shall deliver to the Holder for each $1,000 principal amount of such Note surrendered for conversion (1) a number of shares of Common Stock equal to the Share Payment Component in effect at the time of conversion and (2) an amount of cash (the "Cash Payment Component") equal to the then conversion market value of a number of shares of Common Stock equal to the difference between the Conversion Rate in effect at the time of conversion and the Share Payment Component in effect at that time. The conversion market value shall be determined based on the average Closing Price of the Common Stock for the five consecutive Trading Days immediately following the second Business Day after the date on which the Conversion Agent receives the related conversion notice. In the event that the Shareholder Approval Condition shall have been satisfied, the Company may elect to deliver shares of Common Stock in lieu of paying the Cash Payment Component upon any subsequent conversion of any Note or any portion of the principal amount thereof. If the Company so elects, it shall deliver to the Holder for each $1,000 principal amount of a Note surrendered for conversion a number of shares of Common Stock equal to the Conversion Rate in effect at the time of conversion. The Company shall notify a Holder of its election to deliver Common Stock in lieu of cash within two Business Days after the Conversion Agent receives such Holder's conversion notice, unless the Company shall have given a notice of redemption pursuant to Section 3.04 hereof. The "Conversion Rate" shall initially be 219.1637 and shall be adjusted in certain instances as provided in Section 10.04 hereof. The Share Payment Component shall initially be 76.7073 and shall be subject to adjustment in the same manner and under the same circumstances as the Conversion Rate, subject to any limitation under applicable rules of the New York Stock Exchange. The "Shareholder Approval Condition" shall be satisfied if and when the issuance and delivery of shares of Common Stock upon conversion of the aggregate principal amount of the Notes shall have been approved by a majority of the outstanding shares of Common Stock entitled to vote on the matter. The Company shall use its reasonable efforts to obtain such shareholder approval not later than 180 days after the earliest date of original issuance of any of the Notes. In the event that the Shareholder Approval Condition has been satisfied, the Company shall promptly notify the Holders thereof and use its reasonable efforts to post this information on its website or otherwise publicly disclose this information. SECTION 10.02 Exercise of Conversion Right. To exercise the conversion right, a Holder must satisfy the requirements in paragraph 9 of the Notes. The date on which the Holder satisfies all those requirements is the conversion date (the "Conversion Date") with respect to such Holder's Notes. The Conversion Agent shall notify the Company within one Business Day of receiving a Holder's conversion notice. In the event that the Shareholder Approval Condition shall have been satisfied, within two Business Days after the Conversion Agent receives such Holder's conversion notice, the Company shall deliver to the Holder, through the Conversion Agent, written notice of whether the Company shall pay the Cash Payment Component or deliver shares of Common Stock in lieu thereof, unless the Company shall have delivered a notice of redemption pursuant to Section 3.04. Unless the Shareholder 52 Approval Condition shall have been satisfied and the Company has elected to deliver Common Stock in lieu of the Cash Payment Component, the Company shall deliver to the Holder through the Conversion Agent the amount of cash payable, together with the number of full shares of Common Stock deliverable and cash in lieu of any fractional share determined pursuant to Section 10.03 hereof, no later than the tenth Business Day following the Conversion Date. If the Shareholder Approval Condition shall have been satisfied and the Company shall have notified the Holder that it shall deliver Common Stock in lieu of the Cash Payment Component, the Company shall deliver to the Holder through the Conversion Agent, as promptly as practicable but in any event no later than the fifth Business Day following the Conversion Date, the number of full shares of Common Stock deliverable upon the conversion and cash in lieu of any fractional share determined pursuant to Section 10.03 hereof. The Company may not change its election with respect to the consideration to be delivered upon conversion of a Note (or any portion of the principal amount thereof) once the Company has notified the Holder in accordance with this paragraph. The person in whose name the shares of Common Stock delivered as consideration are registered shall be treated as a stockholder of record on and after the Conversion Date; provided, however, that no surrender of a Note (or any portion of the principal amount thereof) on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such conversion shall be made based on the Conversion Rate and Share Payment Component, as applicable, in effect on the date that such Note shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a Note (or any portion of the principal amount thereof) on the Conversion Date (or such later date as such person is constituted the record holder of the shares of Common Stock into which such Note is converted, as provided for in the proviso to the preceding sentence), such person shall no longer be a Holder of such Note (or such portion of the principal amount thereof). Notes surrendered for conversion, other than those called for redemption pursuant to Section 3.01, during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date shall be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest (including any Liquidated Damages Amounts or Additional Interest Amounts that would be due and payable on such Interest Payment Date) to be received on such Interest Payment Date on the principal amount of Notes being surrendered for conversion. No such payment will be required if the Notes are called for redemption pursuant to Section 3.01. In the case of any Note which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, at the expense of the Company, a new Note or Notes of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Note. If shares of Common Stock to be issued upon conversion of a Restricted Note, or securities to be issued upon conversion of a Restricted Note in part only, are to be registered in a name other than that of the Holder of such Restricted Note, such Holder must deliver to the 53 Conversion Agent a certificate in substantially the form set forth in the form of Note set forth in Exhibit A-1 or A-2 (as applicable) annexed hereto, dated the date of surrender of such Restricted Note and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Note. Neither the Trustee nor any Conversion Agent or Registrar shall be required to register in a name other than that of the Holder shares of Common Stock or Notes issued upon conversion of any such Restricted Note not so accompanied by a properly completed certificate. If the last day on which a Note may be converted is a Legal Holiday, the Note may be surrendered on the next succeeding day that is not a Legal Holiday. The Company hereby initially appoints the Trustee as the Conversion Agent. SECTION 10.03 Fractions of Shares. No fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of any Note or Notes (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-hundredth of a share) in an amount equal to the same fraction of the quoted price of the Common Stock as of the Trading Day preceding the Conversion Date. SECTION 10.04 Adjustment of Conversion Rate. The Conversion Rate shall be subject to adjustments, calculated by the Company, from time to time as follows (without duplication): (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of holders of Common Stock entitled to receive such dividend or other distribution shall be increased by multiplying such Conversion Rate by a fraction: (1) the numerator of which shall be the sum of (x) the number of shares of Common Stock outstanding at the close of business on the Record Date (as defined in Section 10.04(h)) fixed for such determination and (y) the total number of shares constituting such dividend or other distribution payable to the holders of Common Stock; and (2) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date fixed for such determination. Such increase shall become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 10.04(a) is declared but not so paid or made, the Conversion Rate shall again 54 be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. (b) In case the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (c) In case the Company shall issue rights or warrants (other than any rights or warrants referred to in Section 10.04(d)) to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price (as defined in Section 10.04(h)) on the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date after such Record Date by a fraction: (1) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of additional shares of Common Stock so offered to the holders of Common Stock for subscription or purchase (or into which the convertible securities so offered are convertible), and (2) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at such Current Market Price. Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery 55 of only the number of additional shares of Common Stock (or securities convertible into Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such date fixed for the determination of holders of Common Stock entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors. (d) (I) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of the Company (other than any dividends or distributions to which Section 10.04(a) or Section 10.04(g) applies), evidences of indebtedness or other assets (including securities of any Person other than the Company, but excluding (A) any rights or warrants referred to in Section 10.04(c), (B) any stock, securities or other property or assets (including cash) distributed in connection with a reclassification, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 10.11 hereof applies (the securities described in foregoing clauses (A) and (B) hereinafter in this Section 10.04(d) called the "excluded securities") and (C) dividends or distributions paid exclusively in cash), then in each such case the Conversion Rate shall be adjusted so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date (as defined in Section 10.04(h)) with respect to such distribution by a fraction: (1) the numerator of which shall be the Current Market Price on such Record Date (determined as provided in Section 10.04(h)), and (2) the denominator of which shall be such Current Market Price on such Record Date less the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) on such Record Date of the portion of the Capital Stock, evidences of indebtedness or other assets so distributed (other than excluded securities) applicable to one share of Common Stock (determined on the basis of the number of shares of the Common Stock outstanding on such Record Date). Such increase shall become effective immediately prior to the opening of business on the day following the Record Date with respect to such distribution. However, in the event that the then fair market value (as so determined) of the portion of the Capital Stock, evidences of indebtedness or other assets so distributed (other than excluded securities) applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date with respect to such distribution, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of Capital Stock, evidences of indebtedness or other assets so distributed (other than excluded securities) that such Holder would have received had such Holder converted such Note (or portion 56 thereof) immediately prior to such Record Date. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 10.04(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution (other than excluded securities), it must in doing so consider the prices in such market over the same period (the "Reference Period") used in computing the Current Market Price pursuant to Section 10.04(h) to the extent possible, unless the Board of Directors in a Board Resolution determines in good faith that determining the fair market value during the Reference Period would not be in the best interest of the Holder. (II) With respect to any shareholder rights plan existing on the date hereof or in the event that the Company implements any other shareholder rights plan (in each case, a "Rights Agreement"), such rights plan shall provide, subject to customary exceptions and limitations, that upon conversion of the Notes the Holders will receive, in addition to the Common Stock issuable upon such conversion, the rights (the "Rights") issued under such Rights Agreement (notwithstanding the occurrence of an event causing such Rights to separate from the Common Stock at or prior to the time of conversion); provided, a Holder who is a holder of Common Stock (or direct or indirect interests therein) at the time of conversion, but who is not entitled as such a holder to such Rights pursuant to the terms of any such Rights Agreement, shall not be eligible to receive any such Rights hereunder. Any distribution of Rights pursuant to a Rights Agreement complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants for the purposes of this Section 10.04(d). (III) Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.04(d) (and no adjustment to the Conversion Rate under this Section 10.04(d) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or 57 warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). (IV) In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding paragraph) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 10.04(d): (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrant (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants all of which shall have expired or been terminated without exercise, the Conversion Rate shall be readjusted as if such rights and warrants had never been issued. (V) For purposes of this Section 10.04(d) and Sections 10.04(a), 10.04(b) and 10.04(c), any dividend or distribution to which this Section 10.04(d) is applicable that also includes shares of Common Stock, a subdivision or combination of Common Stock to which Section 10.04(b) applies, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 10.04(c) applies (or any combination thereof), shall be deemed instead to be: (1) a dividend or distribution of the evidences of indebtedness, assets, shares of Capital Stock, rights or warrants other than such shares of Common Stock, such subdivision or combination or such rights or warrants to which Sections 10.04(a), 10.04(b) and 10.04(c) apply, respectively (and any Conversion Rate increase required by this Section 10.04(d) with respect to such dividend or distribution shall then be made), immediately followed by (2) a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Rate increase required by Sections 10.04(a), 10.04(b) and 10.04(c) with respect to such dividend or distribution shall then be made), except: (A) the Record Date of such dividend or distribution shall be substituted for (x) "the date fixed for the determination of holders of Common Stock entitled to receive such dividend or other distribution", "Record Date fixed for such determinations" and "Record Date" within the meaning of Section 10.04(a), (y) "the day upon which such subdivision becomes effective" and "the day upon which such combination becomes effective" within the meaning of Section 10.04(b), 58 and (z) "the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants" and "Record Date" within the meaning of Section 10.04(c), and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 10.04(a) and any increase or reduction in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution. (e) In case the Company shall, by dividend or otherwise, distribute (a "Triggering Distribution") to all holders of its Common Stock cash (excluding any cash that is distributed upon a reclassification, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 10.11 hereof applies or as part of a distribution referred to in Section 10.04(d) hereof), in an aggregate amount that, combined together with: (x) the aggregate amount of any other such distributions to all holders of Common Stock made exclusively in cash within the 12 months preceding the date of payment of such Triggering Distribution, and in respect of which no adjustment pursuant to this Section 10.04(e) has been made, and (y) the aggregate of any cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) of any other consideration payable in respect of any tender offer by the Company or any of its subsidiaries for all or any portion of the Common Stock concluded within the 12 months preceding the date of payment of such Triggering Distribution, and in respect of which no adjustment pursuant to Section 10.04(f) hereof has been made, exceeds 5% of the product of the Current Market Price (determined as provided in Section 10.04(h)) on the Business Day (the "Determination Date") immediately preceding the day on which such Triggering Distribution is declared by the Company multiplied by the number of shares of Common Stock outstanding on the Determination Date (excluding shares held in the treasury of the Company), then and in each such case, effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Determination Date by a fraction: (1) the numerator of which shall be equal to such Current Market Price on the Determination Date, and (2) the denominator of which shall be equal to such Current Market Price on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (determined as aforesaid) of any such other 59 consideration so distributed, paid or payable within such 12 months (including, without limitation, the Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Determination Date). However, in the event that the sum of the aggregate amount of cash and the aggregate fair market value (as so determined) of any such other consideration so distributed, paid or payable within such 12 months applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Determination Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of cash such Holder would have received had such Holder converted such Note (or portion thereof) immediately prior to the Record Date with respect to such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. (f) In case a tender offer made by the Company or any of its subsidiaries for all or any portion of the Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall require the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender offer) of Purchased Shares (as defined below)) of an aggregate consideration in an amount (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution) of any other consideration) that, combined together with the aggregate amount of: (x) the aggregate of the cash plus the fair market value (as determined by the Board of Directors, whose determination shall be conclusive and set forth in a Board Resolution), as of the expiration of such tender offer, of consideration payable in respect of any other tender offers by the Company or any of its subsidiaries for all or any portion of the Common Stock expiring within the 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to this Section 10.04(f) has been made, and (y) the aggregate amount of any distributions to all holders of the Company's Common Stock made exclusively in cash within 12 months preceding the expiration of such tender offer and in respect of which no adjustment pursuant to Section 10.04(e) has been made, exceeds 5% of the product of the Current Market Price (determined as provided in Section 10.04(h)) as of the last date (the "Expiration Date") tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes referred to as the "Expiration Time") multiplied by the number of shares of Common Stock outstanding (including any tendered shares) at the Expiration Time, then, and in each such case, immediately prior to the opening of business on the day after the Expiration 60 Date, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to close of business on the Expiration Date by a fraction: (1) the numerator of which shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares of Common Stock validly tendered and not withdrawn as of the Expiration Time (the shares of Common Stock deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the Current Market Price (determined as provided in Section 10.04(h)) of the Common Stock on the Trading Day next succeeding the Expiration Date, and (2) the denominator of which shall be the number of shares of Common Stock outstanding (including any tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by such Current Market Price on the Trading Day next succeeding the Expiration Date. Such increase (if any) shall become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect based upon the number of shares actually purchased. If the application of this Section 10.04(f) to any tender offer would result in a reduction in the Conversion Rate, no adjustment shall be made for such tender offer under this Section 10.04(f). (g) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of Capital Stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit of the Company, then, in each such case, the Conversion Rate shall be adjusted in accordance with the formula: R' = R x (1 + F/M) where: R' = the adjusted Conversion Rate. R = the current Conversion Rate. M = the average of the Post-Distribution Prices of the Common Stock for the 10 Trading Days commencing on and including the fifth Trading Day after the date on which "ex-dividend trading" commences for such dividend or distribution on the 61 principal United States exchange or market which such securities are then listed or quoted (the "Ex-Dividend Date"). F = the fair market value of the securities distributed in respect of each share of Common Stock which for purposes of this Section 10.04(g) shall mean the number of securities distributed in respect of each share of Common Stock multiplied by the average of the Post-Distribution Prices of those securities distributed for the 10 Trading Days commencing on and including the fifth Trading Day after the Ex-Dividend Date. "Post-Distribution Price" of Capital Stock or any similar equity interest on any date means the closing per unit sale price (or, if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date for trading of such units on a "when issued" basis without due bills (or similar concept) as reported in the composite transactions for the principal United States securities exchange on which such Capital Stock or equity interest is traded or, if the Capital Stock or equity interest, as the case may be, is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated; provided that if on any date such units have not traded on a "when issued" basis, the Post-Distribution Price shall be the closing per unit sale price (or, if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date for trading of such units on a "regular way" basis without due bills (or similar concept) as reported in the composite transactions for the principal United States securities exchange on which such Capital Stock or equity interest is traded or, if the Capital Stock or equity interest, as the case may be, is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or by the National Quotation Bureau Incorporated. In the absence of such quotation, the Company shall be entitled to determine the Post-Distribution Price on the basis of such quotations that reflect the post-distribution value of the Capital Stock or equity interests as it considers appropriate. (h) For purposes of this Section 10.04, the following terms shall have the meanings indicated: (1) "Current Market Price" shall mean the average of the daily Closing Prices per share of Common Stock for the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if: (i) the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 10.04(a), (b), (c), (d), (e), (f) or (g) occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; 62 (ii) the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 10.04(a), (b), (c), (d), (e), (f) or (g) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; and (iii) the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (i) or (ii) of this proviso, the Closing Price for each Trading Day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 10.04(d) or (f), whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of Capital Stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Section 10.04(f), the Current Market Price of the Common Stock on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding Trading Days; provided, however, that if the "ex" date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 10.04(a), (b), (c), (d), (e), (f) or (g) occurs on or after the Expiration Date for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, when used: (A) with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution; (B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and 63 (C) with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 10.04, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 10.04 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. (2) "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (3) "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). (i) The Company may make such increases in the Conversion Rate, in addition to those required by Section 10.04(a), (b), (c), (d), (e), (f) or (g), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days and the increase is irrevocable during the period and the Board of Directors determines in good faith that such increase would be in the best interests of the Company, which determination shall be conclusive and set forth in a Board Resolution. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the Trustee and each Holder at the address of such Holder as it appears in the Register a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. (j) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in such rate; provided, however, that any adjustments which by reason of this Section 10.04(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 10 shall be made by the Company and shall be made to the nearest cent or to the nearest one thousandth of a share, as the case may be. No 64 adjustment need be made for a change in the par value or no par value of the Common Stock. (k) In any case in which this Section 10.04 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event (i) issuing to the Holder of any Note converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (ii) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 10.03 hereof. (l) For purposes of this Section 10.04, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. SECTION 10.05 Notice of Adjustments of Conversion Rate. Whenever the Conversion Rate is adjusted as herein provided (other than in the case of an adjustment pursuant to the second paragraph of Section 10.04(i) for which the notice required by such paragraph has been provided), the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers' Certificate setting forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based and the date on which such adjustment becomes effective. Promptly after delivery of such Officers' Certificate, the Company shall prepare a notice stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective, and shall mail such notice to each Holder at the address of such Holder as it appears in the Register within 20 days of the effective date of such adjustment. Failure to deliver such Officers' Certificate or such notice shall not affect the legality or validity of any such adjustment. SECTION 10.06 Notice Prior to Certain Actions. In case at any time after the date hereof: (1) the Company shall declare a dividend (or any other distribution) on its Common Stock payable otherwise than in cash out of its capital surplus or its consolidated retained earnings; (2) the Company shall authorize the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any shares of Capital Stock of any class (or of securities convertible into shares of Capital Stock of any class) or of any other rights; (3) there shall occur any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, a change in par value, a change from par value to no par value or a change from no par value to par value), or any merger, consolidation, statutory share exchange or 65 combination to which the Company is a party and for which approval of any shareholders of the Company is required, or the sale, transfer or conveyance of all or substantially all of the assets of the Company; or (4) there shall occur the voluntary or involuntary dissolution, liquidation or winding up of the Company; the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Notes pursuant to Section 4.05 hereof, and shall cause to be provided to the Trustee and all Holders in accordance with Section 13.02 hereof, at least 20 days (or 10 days in any case specified in clause (1) or (2) above) prior to the applicable record or effective date hereinafter specified, a notice stating: (A) the date on which a record is to be taken for the purpose of such dividend, distribution, rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined, or (B) the date on which such reclassification, merger, consolidation, statutory share exchange, combination, sale, transfer, conveyance, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, merger, consolidation, statutory share exchange, sale, transfer, dissolution, liquidation or winding up. Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings or actions described in clauses (1) through (4) of this Section 10.06. SECTION 10.07 Company to Reserve Common Stock. The Company shall at all times use its best efforts to reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Notes, the full number of shares of fully paid and nonassessable Common Stock then issuable upon the conversion of all Notes outstanding. SECTION 10.08 Taxes on Conversions. Except as provided in the next sentence, the Company will pay any and all taxes (other than taxes on income) and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto. A Holder delivering a Note for conversion shall be liable for and will be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Note or Notes to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid. SECTION 10.09 Covenant as to Common Stock. The Company covenants that all shares of Common Stock which may be issued upon conversion of Notes will upon issue 66 be fully paid and nonassessable and, except as provided in Section 10.08, the Company will pay all taxes, liens and charges with respect to the issue thereof. SECTION 10.10 Cancellation of Converted Notes. All Notes delivered for conversion shall be delivered to the Trustee to be canceled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 2.10. SECTION 10.11 Effect of Reclassification, Consolidation, Merger or Sale. If any of following events occur, namely: (1) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (2) any merger, consolidation, statutory share exchange or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash or any combination thereof) with respect to or in exchange for such Common Stock, or (3) any sale or conveyance of all or substantially all of the properties and assets of the Company to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash or any combination thereof) with respect to or in exchange for such Common Stock, the Company or the successor or purchasing corporation, as the case may be, shall, as a condition precedent to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that such Note shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash or any combination thereof) which such Holder would have been entitled to receive upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance had such Notes been converted into Common Stock immediately prior to such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance assuming such holder of Common Stock did not exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance (provided that, if the kind or amount of securities, cash or other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised ("Non-Electing Share"), then for the purposes of this Section 10.11 the kind and amount of securities, cash or other property receivable upon such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance for each Non-Electing Share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-Electing Shares). Such 67 supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 10. If, in the case of any such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Section 3.09 hereof. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 10.11 shall similarly apply to successive reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances. If this Section 10.11 applies to any event or occurrence, Section 10.04 hereof shall not apply. SECTION 10.12 Responsibility of Trustee for Conversion Provisions. The Trustee, subject to the provisions of Section 7.01 hereof, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder of Notes to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or intent of any such adjustments when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same or the calculation thereof. Neither the Trustee, subject to the provisions of Section 7.01 hereof, nor any Conversion Agent shall be accountable with respect to the validity or value (of the kind or amount) of any Common Stock, or of any other securities or property, which may at any time be issued or delivered upon the conversion of any Note; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 7.01 hereof, nor any Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or share certificates or other securities or property upon the surrender of any Note for the purpose of conversion; and the Trustee, subject to the provisions of Section 7.01 hereof, and any Conversion Agent shall not be responsible or liable for any failure of the Company to comply with any of the covenants or other obligations of the Company contained in this Article. 68 ARTICLE 11 DIVIDEND PROTECTION PAYMENT SECTION 11.01 Additional Interest Amounts. In the event the Company declares a dividend on its Common Stock, the Company shall pay to each Holder of record as of the record date for such dividend an amount equal to the product of (i) such per share dividend declared by the Company multiplied by (ii) the number of shares of Common Stock such Holder would possess had such Holder converted its Notes into a number of shares of Common Stock equal to the Conversion Rate as of the record date for such dividend (each such payment an "Additional Interest Amount and, collectively the "Additional Interest Amounts"); provided, however, that such amount shall not be due and no payment with respect thereto shall be made with respect to the Notes unless such dividend is paid to holders of Common Stock. The payment date for an Additional Interest Amount shall be the same as the payment date for the dividend to which the Additional Interest Amount relates. Holders of Notes shall not be entitled to receive any Additional Interest Amount with respect to any dividend that causes an adjustment to the Conversion Rate.

(a) On the date of this Indenture, the Company shall (i) enter into the Pledge Agreement and comply with the terms and provisions thereof and (ii) purchase the Pledged Securities to be pledged to the Trustee for the benefit of the Holders in such amount as will be sufficient upon receipt of scheduled interest and/or of principal payments of such Pledged Securities to provide for payment in full of the first five scheduled interest payments (up to and including the interest payment due on August 14, 2005) due on the Notes. The Pledged Securities shall be pledged by the Company to the Trustee for the benefit of the Holders and shall be held by the Trustee in the Pledge Account pending disposition pursuant to the Pledge Agreement. (b) Each Holder, by its acceptance of a Note, consents and agrees to the terms of the Pledge Agreement (including, without limitation, the provisions providing for foreclosure and release of the Pledged Securities) as the same may be in effect or may be amended from time to time in accordance with its terms, and authorizes and directs the Trustee to enter into the Pledge Agreement and to perform its respective obligations and exercise its respective rights thereunder in accordance therewith. The Company will do or cause to be done all such acts and things as may be necessary or reasonably requested by the Trustee, or as may be required by the provisions of the Pledge Agreement, to assure and confirm to the Trustee the security interest in the Pledged Securities contemplated hereby, by the Pledge Agreement or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes herein and therein expressed. The Company, in consultation with the Trustee, shall take, or shall cause to be taken, any and all actions reasonably required to cause the Pledge Agreement to create and maintain, as security for the obligations of the Company under this Indenture and the Notes, 69 valid and enforceable first priority liens in and on all the Pledged Securities, in favor of the Trustee, superior to and prior to the rights of third Persons and subject to no other Liens. (c) The release of any Pledged Securities pursuant to the Pledge Agreement will not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Pledged Securities are released pursuant to this Indenture and the Pledge Agreement. To the extent applicable, the Company shall cause TIA Section 314(d) relating to the release of property or securities from the Lien and security interest of the Pledge Agreement and relating to the substitution therefor of any property or securities to be subjected to the Lien and security interest of the Pledge Agreement to be complied with. Any certificate or opinion required by TIA Section 314(d) may be made by an Officer of the Company, except in cases where TIA Section 314(d) requires that such certificate or opinion be made by an independent Person, which Person shall be an independent engineer, appraiser or other expert selected by the Company. (d) The Company shall cause TIA Section 314(b), relating to opinions of counsel regarding the Lien under the Pledge Agreement, to be complied with. The Trustee may accept, to the extent permitted by Sections 4.03 and 7.13 as conclusive evidence of compliance with the foregoing provisions, the appropriate statements contained in such instruments. (e) The Trustee may, in its sole discretion and without the consent of the Holders, on behalf of the Holders, take all reasonable actions in accordance with the Pledge Agreement necessary or appropriate in order to (i) enforce any of the terms of the Pledge Agreement and (ii) collect and receive any and all amounts payable in respect of the obligations of the Company thereunder. The Trustee shall have power to institute and to maintain such suits and proceedings as the Trustee may reasonably deem expedient to preserve or protect its interests and the interests of the Holders in the Pledged Securities (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders or of the Trustee).
