In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion as to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, or a certificate or representations by counsel, unless such officer knows, or in the exercise of reasonable care should know, that the opinion, certificate or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such Opinion of Counsel or certificate or representations may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information as to such factual matters is -9- <PAGE> in the possession of the Company, unless such counsel knows that the certificate or opinion or representations as to such matters are erroneous. Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. Section 1.04 Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders of the Outstanding Securities, may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments or so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section 1.04. (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other reasonable manner which the Trustee deems sufficient. (c) The ownership of the Securities shall be proved by the Security Register. (d) (i) If the Company shall solicit from the Holders of any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, in or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so; provided that the Company shall not be entitled to set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in clause 1.04(d)(iii) below. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such -10- <PAGE> 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 the purposes of determining whether Holders of the requisite proportion of Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities 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 eleven months after the record date. (ii) Subject to clause 1.04(d)(iii) below, in the absence of any such record date fixed by the Company, regardless as to whether any solicitation of the Holders is occurring on behalf of the Company or any Holder, the Trustee may, at its option, fix in advance a record date for the determination of such Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Trustee shall have no obligation to do so. Any such record date shall be a date not more than 30 days prior to the first solicitation of Holders generally in connection therewith and no later than the date of such solicitation. (iii) The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities entitled to join in the giving or making of (A) any notice of default, (B) any declaration of acceleration referred to in Section 5.02, (C) any request to institute proceedings referred to in Section 5.07(b), or (D) any direction referred to in Section 5.12. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to any applicable expiration date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action (whereupon the record date previously set shall automatically and without any action by any Person be cancelled and of no effect), nor shall anything in this paragraph be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company's expense, shall cause notice of such record date, the proposed action by Holders and the applicable expiration date to be given to the Company in writing and to each Holder of Securities in the manner set forth in Section 1.06. (e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee, any Security Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such action is made upon such Security. -11- <PAGE> Section 1.05 Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: (a) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: Capital Markets Fiduciary Services; provided that notices to the Trustee shall only be deemed given when actually received by the Trustee, (b) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this Indenture or at any other address previously furnished in writing to the Trustee by the Company. Section 1.06 Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders by the Company or the Trustee, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each such Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders given as provided herein. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. If by reason of the suspension of or irregularities in regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification to Holders as shall be made with the approval of the Trustee shall constitute a sufficient notification to such Holders for every purpose hereunder. Any request, demand, authorization, direction, notice, consent or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication. Where this Indenture provides for notice in any manner, such notice maybe waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. Section 1.07 Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. -12- <PAGE> Section 1.08 Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. Section 1.09 Separability Clause. In case any provision in this Indenture or in any Security shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. Section 1.10 Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto, any Security Registrar, any Paying Agent and their successors hereunder and the Holders any benefit or any legal or equitable right, remedy or claim under this Indenture. Section 1.11 Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York without regard to conflicts of laws principles. This Indenture is subject to the provisions of the TIA that are required to be part of this Indenture and shall, to the extent applicable, be governed by such provisions. Section 1.12 Legal Holidays. In any case where any Interest Payment Date, Redemption Date, Repurchase Date, Stated Maturity or Maturity of any Security or the last date on which a Holder has the right to convert his Securities shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security), payment of Redemption Price, Repurchase Price, interest or principal (and premium, if any), or conversion of the Securities, need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date, Redemption Date, Repurchase Date or at the Stated Maturity or Maturity or on such last day for conversion; provided that no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date, Repurchase Date, Stated Maturity or Maturity or on such last day for conversion, as the case may be. Section 1.13 Personal Immunity from Liability for Incorporators, Stockholders, Etc. No recourse shall be had for the payment of the principal of or premium, if any, or interest, if any, on any Security, or for any claim based thereon, or otherwise in respect of any Security, or based on or in respect of this Indenture or any indenture supplemental hereto, against any incorporator, or against any past, present or future stockholder, director or officer, as such, of the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being expressly waived and released as a condition of, and as consideration for, the execution of this Indenture and the issue of Securities. Section 1.14 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the TIA which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the TIA which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case -13- <PAGE> may be. To the extent a Security conflicts with a provision in the Indenture, the Indenture governs. ARTICLE II Securities Forms Section 2.01 Forms of Securities. The Securities shall be in substantially the form of Exhibit A hereto, and shall have notations, legends or endorsements required by law, stock exchange rate or usage. Except as otherwise provided in a Company Order, all Securities other than Securities issuable in global form shall be issued in definitive form and shall include a legend substantially in the Form of Exhibit A-2 attached hereto. Section 2.02 Form of Trustee's Certificate of Authentication. The Trustee's certificate of authentication shall be in substantially the following form: This is one of the Securities described in the within-mentioned Indenture. DATED: -------------------------------- as Trustee By: ----------------------------- Authorized Signatory Section 2.03 Securities Issuable in Global Form. Except as otherwise provided in this Section 2.03, the Securities shall be issuable in global form, and any such Security shall represent such of the Outstanding Securities as shall be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities from time to time endorsed thereon and that the aggregate amount of Outstanding Securities represented thereby may from time to time be increased or decreased to reflect exchanges. Any endorsement of a Security in global form to reflect the amount, or any increase or decrease in the amount, of Outstanding Securities represented thereby shall be made by the Trustee in such manner and upon instructions given by such Person or Persons as shall be specified therein or in the Company Order to be delivered to the Trustee pursuant to Section 3.03. Subject to the provisions of Section 3.03, the Trustee shall deliver and redeliver any Security in global form in the manner and upon instructions given by the Person or Persons specified therein or in the applicable Company Order. If a Company Order pursuant to Section 3.03 has been, or simultaneously is, delivered, any instructions by the Company with respect to endorsement or delivery or redelivery of a Security in global form shall be in writing but need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel. -14- <PAGE> The provisions of the last sentence of Section 3.03 shall apply to any Security represented by a Security in global form if such Security was never issued and sold by the Company and the Company delivers to the Trustee the Security in global form together with written instructions (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) with regard to the reduction in the principal amount of Securities represented thereby, together with the written statement contemplated by the last sentence of Section 3.03. Notwithstanding the provisions of Section 3.07, payment of principal of and any premium and interest on any Security in global form shall be made to the Person or Persons specified therein. Notwithstanding the provisions of Section 3.07 and except as provided in the preceding paragraph, the Company, the Trustee and any agent of the Company and the Trustee shall treat as the Holder of such principal amount of Outstanding Securities represented by a global Security as the Holder of such global Security in registered form. At the instruction of the Company, any Security may be issued in definitive form, subject to Section 2.01 hereof. ARTICLE III The Securities Section 3.01 Title and Term. The Securities shall be and are hereby authorized to be designated as "5 1/2% Convertible Subordinated Notes due 2004", limited in aggregate principal amount to $566,250,000. The Securities shall mature and the principal thereof shall be due and payable, together will all accrued and unpaid interest thereon, on December 21, 2004. The Securities shall be convertible into shares of Common Stock, $0.001 par value, of the Company, as such shares shall be constituted at the time of conversion, in accordance with Article 13 hereof. Section 3.02 Denominations. The Securities shall be issuable in denominations of $1,000 and any integral multiple thereof. Section 3.03 Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by the Chief Executive Officer, Chief Financial Officer, the President, a Vice President or a Managing Director of the Company and attested by its Secretary or one of its Assistant Secretaries. The signature of any of these individuals on the Securities may be manual or facsimile signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Securities. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such -15- <PAGE> individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities, executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.08 together with a written statement (which need not comply with Section 1.02 and need not be accompanied by an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. Section 3.04 Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee or in any office or agency of the Company in a Place of Payment a register for the Securities (the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Securities and of transfers of the Securities. The Security Register shall be in written form or any other form capable of being converted into written form within a reasonable time. The Trustee, at its Corporate Trust Office, is hereby appointed "Security Registrar" for the purpose of registering the Securities and transfers of the Securities on such Security Register as herein provided. In the event that the Trustee shall cease to be Security Registrar, it shall have the right to examine the Security Register at all reasonable times. Subject to the provisions of this Section 3.04 and except as otherwise provided in any Security including any legend thereon, upon surrender for registration of transfer of any Security at any office or agency of the Company in a Place of Payment, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities, of any authorized denominations and of a like aggregate principal amount, bearing a number not contemporaneously outstanding, and containing identical terms and provisions. Subject to the provisions of this Section 3.04, at the option of the Holder, the Securities may be exchanged for other Securities, of any authorized denomination or -16- <PAGE> denominations and of a like aggregate principal amount, containing identical terms and provisions, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any such Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. Notwithstanding the foregoing, any global Security shall be exchangeable only as provided in this paragraph. The depositary for the global Securities shall be DTC, and the global Securities may be transferred, in whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for such global Security selected or approved by the Company or to a nominee of such successor to DTC. If at any time DTC notifies the Company that it is unwilling or unable to continue as depositary for the applicable global Security or Securities or if at any time DTC ceases to be a clearing agency registered under the Securities Exchange Act of 1934 if so required by applicable law or regulation, the Company shall appoint a successor depositary with respect to such global Security or Securities. If (x) a successor depositary for such global Security or Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such unwillingness, inability or ineligibility, (y) an Event of Default has occurred and is continuing and the beneficial owners representing a majority in principal amount of the applicable Securities represented by such global Security or Securities advise DTC to cease acting as depositary for such global Security or Securities or (z) the Company, in its sole discretion, determines at any time that all Outstanding Securities (but not less than all) issued or issuable in the form of one or more global Securities shall no longer be represented by such global Security or Securities, then the Company shall execute, and the Trustee shall authenticate and deliver, definitive Securities of like rank, tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such global Security or Securities. If a Security is issued in exchange for any portion of a global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date or (ii) any Special Record Date and the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such global Security is payable in accordance with the provisions of this Indenture. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the Company or the Security Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the -17- <PAGE> Company and the Security Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 10.05, 11.07 or 12.03(f) not involving any transfer. The Company or the Trustee, as applicable, shall not be required (i) to issue, register the transfer of or exchange any Security if such Security may be among those selected for redemption during a period beginning at the opening of business 15 days before selection of the Securities to be redeemed under Section 11.03 and ending at the close of business on the day of the mailing of the relevant notice of redemption or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except, in the case of any Security to be redeemed in part, the portion thereof not to be redeemed, or (iii) to issue, register the transfer of or exchange any Security which has been surrendered for repayment at the option of the Holder, except the portion, if any, of such Security not to be so repaid. Section 3.05 Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee or the Company, together with such security or indemnity as may be required by the Company or the Trustee to save each of them or any agent of either of them harmless, the Company shall, at the relevant Holder's expense, execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company, at the relevant Holder's expense, shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same principal amount, containing identical terms and provisions and bearing a number not contemporaneously outstanding, appertaining to such destroyed, lost or stolen Security. Notwithstanding the provisions of the previous two paragraphs, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, 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. -18- <PAGE> Every new Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security, shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. The provisions of this Section 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 Securities. Section 3.06 Payment of Interest; Interest Rights Preserved. Interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose pursuant to Section 10.02; provided, however, that each installment of interest on any Security may at the Company's option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 3.07, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the payee located inside the United States; provided, however, that payments to DTC will be made by wire transfer of immediately available funds to the account of DTC or its nominee. The term "Regular Record Date" with respect to any Interest Payment Date shall mean the December 6 or June 6 preceding December 21 or June 21, respectively. Any interest on any Security that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause 3.06(a) or 3.06(b) below: (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment (which shall not be less than 30 days after such notice is received by the Trustee) and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at -19- <PAGE> the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities at his address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an Authorized Newspaper in each place of payment, but such publications shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). (b) The Company may make payment of any Defaulted Interest on the Securities in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. Section 3.07 Persons Deemed Owners. Prior to due presentment of a Security 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 Security is registered as the owner of such Security for the purpose of receiving payment of principal of (and premium, if any), and (subject to Sections 3.04 and 3.06) interest on, such Security and for all other purposes whatsoever, whether or not such Security 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. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Security in global form or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Notwithstanding the foregoing, with respect to any global Security, 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 any depositary, as a Holder, with respect to such global Security or impair, as between such depositary and owners of beneficial interests in such global Security, the operation of customary practices governing the exercise of the rights of such depositary (or its nominee) as Holder of such global Security. Section 3.08 Cancellation. All Securities surrendered for payment, redemption, repayment at the option of the Holder, registration of transfer or exchange or for credit against -20- <PAGE> any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities surrendered directly to the Trustee for any such purpose shall be promptly canceled by it; provided, however, where the Place of Payment is located outside of the United States, the Paying Agent at such Place of Payment may cancel the Securities surrendered to it for such purposes prior to delivering the Securities to the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. If the Company shall so acquire any of the Securities, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Securities unless and until the same are surrendered to the Trustee for cancellation. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. Canceled Securities held by the Trustee shall be destroyed by the Trustee and the Trustee shall deliver a certificate of such destruction to the Company, unless by a Company Order the Company directs their return to it.

ARTICLE IV Satisfaction and Discharge Section 4.01 Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect with respect to any Security specified in such Company Request (except as to any surviving rights of conversion, registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, upon receipt of a Company Order, and at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture when: (a) either: (i) all Securities theretofore authenticated and delivered have been delivered to the Trustee for cancellation; or (ii) all Securities not theretofore delivered to the Trustee for cancellation: (A) have become due and payable, or (B) will become due and payable at their Stated Maturity within one year, or -21- <PAGE> (C) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (A), (B) or (C) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust (1) an amount of money, (2) Government Obligations that through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (3) a combination thereof, sufficient in each case to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee and any predecessor Trustee under Section 6.07, and, if money shall have been deposited with and held by the Trustee pursuant to Section 4.01(a)(ii), the obligations of the Trustee under Section 4.02 and the last paragraph of Section 10.03 shall survive. Section 4.02 Application of Trust Funds. Subject to the provisions of the last paragraph of Section 10.03, all amounts deposited with the Trustee pursuant to Section 4.01 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent), as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and any interest for whose payment such amounts have been deposited with or received by the Trustee, but such amounts need not be segregated from other funds except to the extent required by law. All moneys deposited with the Trustee pursuant to Section 4.01 (and held by it or any Paying Agent) for the payment of Securities subsequently converted shall be returned to the Company upon Company Request. -22- <PAGE> ARTICLE V Remedies Section 5.01 Events of Default. "Event of Default," wherever used herein with respect to the Securities, means any one of the following events (whatever the reason for such Event of Default and whether or not it shall be occasioned by the provisions of Article 14 or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) default in the payment of any interest upon any Security, when such interest becomes due and payable, and continuance of such default for a period of 30 days (whether or not such payment is prohibited by the provisions of Article 14); or (b) default in the payment of (i) the principal of (or premium, if any, on) any Security when it becomes due and payable at its Maturity, or (ii) the payment of the Redemption Price (including the Make-Whole Payment, if any) with respect to any Security when it becomes due and payable (whether or not such payment is prohibited by the provisions of Article 14); or (c) default in the payment of the Repurchase Price in respect of any Security on the Repurchase Date therefor (whether or not such payment is prohibited by the provisions of Article 14 hereof); or (d) failure by the Company to 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 following conversion of a Security and continuation of such default for a period of 10 days; or (e) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture with respect to any Security (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with) and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (f) a default under any bonds, debentures, notes or other evidences of indebtedness for money borrowed of the Company or under any mortgages, indentures or instruments under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company, whether such indebtedness now exists or shall hereafter be created, which indebtedness, individually or in the aggregate, has a principal amount outstanding in excess of $10,000,000, which default shall have resulted in such -23- <PAGE> indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such indebtedness having been discharged, or such acceleration having been rescinded or annulled, within a period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Securities then Outstanding, a written notice specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a "Notice of Default" hereunder (unless such default has been cured or waived); or (g) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, or (iv) makes a general assignment for the benefit of its creditors; or (h) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Company or any Significant Subsidiary in an involuntary case, (ii) appoints a Custodian of the Company or any Significant Subsidiary or for all or substantially all of the property of any of them, or (iii) 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. As used in this Section 5.01, the term "Bankruptcy Law" means title 11, U.S. Code or any similar Federal or State law for the relief of debtors and the term "Custodian" means any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy Law. Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities at the time Outstanding occurs and is continuing, then and in -24- <PAGE> every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities may declare the principal of all the Securities to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal shall become immediately due and payable. If an Event of Default specified in Section 5.01(g) or 5.01(h) occurs, the principal of, and accrued interest on, all the Securities shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. At any time after such a declaration of acceleration with respect to Securities has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: (a) the Company has paid or deposited with the Trustee a sum sufficient to pay: (i) all overdue installments of interest on all Outstanding Securities, (ii) the principal of (and premium, if any, on) any Outstanding Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Securities, (iii) to the extent that payment of such interest is lawful, interest upon overdue installments of interest at the rate or rates borne by or provided for in such Securities, and (iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (b) all Events of Default with respect to Securities, other than the nonpayment of the principal of (or premium, if any) or interest on Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. No such rescission shall affect any subsequent default or impair any right consequent thereon. Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if: (a) default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or -25- <PAGE> (b) default is made in the payment of the principal of (or premium, if any, on) any Security at its Maturity, then the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, with interest upon any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest, if any, at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. If an Event of Default with respect to Securities occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. Section 5.04 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 Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities 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 overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise: (a) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities, of principal (and premium, if any) and interest, owing and unpaid in respect of the Securities 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) 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; -26- <PAGE> and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or other similar official) in any such judicial proceeding is hereby directed by each Holder of Securities to make such payments to the Trustee, and in the event that the Trustee shall request the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee and any predecessor Trustee, their agents and counsel, and any other amounts due the Trustee or any predecessor Trustee under Section 6.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security, any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding; provided; however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee. Section 5.05 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or any of the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. Section 5.06 Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under Section 6.07; SECOND: To the holders of Senior Indebtedness to the extent required by the provisions of Article 14. THIRD: To the payment of the amounts then due and unpaid upon the Securities for principal (and premium, if any) and interest payable, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on such Securities for principal (and premium, if any) and, interest, respectively; and FOURTH: To the payment of the remainder, if any, to the Company. -27- <PAGE> Section 5.07 Limitation on Suits. No Holder of any Security shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities; (b) the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (c) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request; (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. Section 5.08 Unconditional Right of Holders to Receive Principal, Premium, If Any, and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right which is absolute and unconditional to receive payment of the principal of, and premium, if any, including the Redemption Prices and Make-Whole Payment upon redemption pursuant to Article 11, and (subject to Sections 3.04 and 3.06) interest on such Security on the respective due dates expressed in such Security (or, in the case of redemption or repurchase, on the Redemption Date or Repurchase Date, as the case may be) and to convert such Security in accordance with the provisions of this Indenture and to institute suit for the enforcement of any such payment and right to convert, and such rights shall not be impaired without the consent of such Holder. Section 5.09 Restoration of Rights and Remedies. If the Trustee or any Holder of a Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, the Company, the Trustee and the Holders of Securities shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder and thereafter all rights -28- <PAGE> and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. Section 5.10 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.05, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Section 5.11 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as the case may be. Section 5.12 Control by Holders of Securities. The Holders of not less than a majority in principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities, provided that: (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and (c) the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders of Securities not joining therein. Section 5.13 Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities may on behalf of the Holders of all the Securities waive any past default hereunder with respect to such Securities and its consequences, except a default: (a) in the payment of the principal of (or premium, if any) or interest on any Security, (b) in respect of the conversion by the Company of any Security into Common Stock, -29- <PAGE> (c) in the payment of the Redemption Prices or Make-Whole Payment pursuant to Article 11, (d) in the payment of the Repurchase Price pursuant to Article 12, or (e) in respect of a covenant or provision hereof which under Article 9 cannot be modified or amended without the consent of the Holder of each Outstanding Security affected. Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Section 5.14 Waiver of Usury, Stay or Extension 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 usury, stay or extension law wherever enacted, now or at any time hereafter in force, 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 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. Section 5.15 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, 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, the filing by any party litigant in such suit of any undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption or repurchase, on or after the Redemption Date or the Repurchase Date, respectively), or the right to convert any Security in accordance with Article 13. -30- <PAGE> ARTICLE VI The Trustee Section 6.01 General. The duties and responsibilities of the Trustee shall ------- be as provided by the TIA and as set forth herein. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if the Trustee in its sole discretion shall believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Whether or not herein 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 Article 6. Section 6.02 Certain Rights of Trustee. Subject to TIA Sections 315(a) through (d): (a) the Trustee may rely, and shall be protected in acting or refraining from acting, upon any resolution, certificate, statement, instrument, facsimile transmission, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed, made or presented by the proper person and may accept and rely upon the same as conclusive evidence of the truth and accuracy of the statement and opinions contained therein. The Trustee need not investigate any fact or matter stated in any such document; (b) before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel, which shall conform to Section 1.02.

The Trustee, any Paying Agent, Security Registrar or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, its Subsidiaries or its Affiliates with the same rights it would have if it were not the Trustee, Paying Agent, Security Registrar or such other agent. Any registrar, co-registrar, paying agent, conversion agent or authenticating agent may do the same with like rights. However, the Trustee is subject to TIA Sections 310(b) and 311. Section 6.04 Trustee's Disclaimer. The Trustee (i) makes no representation as to the validity or adequacy of this Indenture or the Securities, (ii) shall not be accountable for the Company's use or application of the proceeds from the Securities and (iii) shall not be responsible for any statement in the Securities other than its certificate of authentication. Section 6.05 Notice of Default. If any Event of Default occurs and is continuing and if the Trustee has actual knowledge of such Event of Default, the Trustee shall mail to each holder in the manner and to the extent provided in TIA Section 313(c) notice of the Event of Default within 90 days after it occurs, unless such Event of Default has been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Security, the Trustee shall be protected in withholding such notice if and so long as Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders of the Securities; and provided further that in the case of any default or breach referred to in Section 5.01(e) with respect to the Securities, no such notice to Holders shall be given until at least 90 days after the occurrence thereof. For the purpose of this Section, the term "default" means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to the Securities. Section 6.06 Conflicting Interests of Trustee. 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 and this Indenture. Section 6.07 Compensation and Indemnity. The Company shall pay to the Trustee such compensation as shall be agreed upon in writing for its services. The compensation of the Trustee shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses and advances incurred or made by the Trustee in accordance with this Indenture. Such expenses shall include the reasonable compensation and expenses of the Trustee's agents and counsel. The Company shall indemnify and hold harmless the Trustee and its directors, agents and employees (collectively the "Indemnitees") against any and all losses, liabilities, obligations, damages, penalties, fines, judgments, actions, suits, proceedings, reasonable costs and expenses (including reasonable fees and disbursements of counsel) of any kind whatsoever which may be incurred by or imposed on the Indemnitees or any of them arising out of or in connection with the acceptance or administration of its duties under this Indenture; provided, however, that the Company need not reimburse any expense or indemnify against any loss, -33- <PAGE> obligation, damage, penalty, fine, judgment, action, suit, proceeding, reasonable cost or expense (including reasonable fees and disbursements of counsel) of any kind whatsoever which may be incurred by Indemnitees or any of them which results from the negligence or willful misconduct of the Indemnitees or any of them. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder, unless the Company is materially prejudiced thereby. The Company shall defend the claim and the Trustee shall cooperate in the defense. Unless otherwise set forth herein, the Indemnitees of any of them may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The provisions of this Section 6.07 shall survive the termination of this Indenture and the resignation or removal of the Trustee for any reason. To secure the Company's payment obligations in this Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, in its capacity as Trustee, except money or property held in trust to pay principal of, premium, if any, and interest on particular Securities. If the Trustee incurs expenses or renders services after the occurrence of an Event of Default specified in Section 5.01(g) or Section 5.01(h), the expenses and the compensation for the services will be intended to constitute expenses of administration under Title 11 of the United States Bankruptcy Code or any applicable federal or state law for the relief of debtors. Section 6.08 Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 6.08. The Trustee may resign at any time by so notifying the Company in writing at least thirty (30) days prior to the date of the proposed resignation. The holders of a majority in principal amount of the Outstanding Securities may remove the Trustee by so notifying the Trustee in writing and may appoint a successor Trustee with the prior consent of the Company. The Company may remove the Trustee if: (i) the Trustee is no longer eligible under Section 6.10; (ii) the Trustee is adjudged a bankrupt or an insolvent; (iii) a receiver or other public officer takes charge of the Trustee or its property; or (iv) the Trustee becomes incapable of acting. If the Trustee resigns or is removed, or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the holders of a majority in principal amount of the Outstanding Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

Any notice that is mailed to the Holders of Securities in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. All notices of redemption shall state: (a) the Redemption Date; (b) the Redemption Price, accrued interest to the Redemption Date payable as provided in Section 11.06, if any, and, with respect to Securities called for Provisional Redemption, the Make-Whole Payment; -46- <PAGE> (c) if less than all Outstanding Securities are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Securities to be redeemed; (d) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the holder will receive, without a charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed; (e) that on the Redemption Date, the Redemption Price and accrued interest to the Redemption Date payable as provided in Section 11.06, if any, and, with respect to Securities called for Provisional Redemption, the Make- Whole Payment, will become due and payable upon each such Security, or the portion thereof, to be redeemed and, if applicable, that interest thereon shall cease to accrue on and after said date; (f) the Place or Places of Payment where such Securities, maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price and accrued interest, if any, and, with respect to Securities called for Provisional Redemption, the Make-Whole Payment, or for conversion, (g) that Securities called for redemption must be presented and surrendered to the Paying Agent to collect the redemption price; (h) the then current Conversion Price; (i) that the Securities called for redemption may be converted at any time before the close of business on the Redemption Date; (j) the CUSIP number of such Security, if any; and (k) that a Holder of Securities who desires to convert Securities must satisfy the requirements for conversion contained in such Securities.

Not later than 11:00 a.m. New York City time on the Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03) an amount of money sufficient to pay on the Redemption Date, the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, and, with respect to the Securities called for Provisional Redemption, the Make-Whole Payment on, all the Securities or portions thereof which are to be redeemed on that date, other than Securities or portions thereof called for redemption on that date which have been delivered by the Company to the Trustee for cancellation or have been converted; provided that, -47- <PAGE> with respect to a Provisional Redemption, any money so deposited for payment of the Make-Whole Payment shall remain segregated and held in trust for payment of the Make-Whole Payment which shall be made on all Securities called for Provisional Redemption, including Securities converted into shares of Common Stock after the Notice Date and prior to the Provisional Redemption Date. Section 11.06 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified (together with accrued interest, if any, to the Redemption Date), and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall, if the same were interest-bearing, cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date and with respect to Securities called for Provisional Redemption (including Securities converted into Common Stock pursuant to the terms hereof after the Notice Date and prior to the Provisional Redemption Date), the Make-Whole Payment; and provided, however, that if the Provisional Redemption Date is an Interest Payment Date, the semi-annual payment of interest becoming due on such date shall be payable to the Holders of such Securities registered as such on the relevant Regular Record Date according to their terms and the provisions of Section 3.06, and with respect to a Provisional Redemption, the holder of any Securities converted into Common Stock pursuant to the terms hereof after the Notice Date and prior to the Provisional Redemption Date shall have the right to the Make-Whole Payment regardless of the conversion of such Securities. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any (including the Make-Whole Payment, if any), shall, until paid, bear interest from the Redemption Date at the rate borne by the Security and such Security shall remain convertible into Common Stock until the principal and premium, if any (including the Make-Whole Payment, if any), shall have been paid. Section 11.07 Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article) shall be surrendered at a Place of Payment therefor (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 his attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge a new Security or Securities, 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 Security so surrendered. -48- <PAGE> ARTICLE XII Repurchase at Option of Holders upon Change in Control Section 12.01 Right to Require Repurchase. In the event that a Change in Control shall occur, each Holder shall have the right, at the Holder's option, to require the Company to repurchase (subject to the provisions of Section 14.03 hereof), and upon the exercise of such right the Company shall repurchase, all of such Holder's Securities, or any portion of the principal amount thereof that is an integral multiple of $1,000 (provided that no single Security may be repurchased in part unless the portion of the principal amount of such Security to be outstanding after such repurchase is equal to $1,000 or an integral multiple of $1,000), on the date (the "Repurchase Date") that is not later than 45 Business Days after the date of the occurrence of a Change in Control at a purchase price equal to 100% of the principal amount plus interest accrued and unpaid to the Repurchase Date (subject to the right of Holders of record on the Regular Record Date to receive interest on the relevant Interest Payment Date) (the "Repurchase Price"). At the option of the Company, the Repurchase Price may be paid in cash or, subject to the fulfillment by the Company of the conditions set forth in Section 12.02, by delivery of shares of Common Stock having a fair market value equal to the Repurchase Price as described in Section 12.02. If the Repurchase Date is between a Regular Record Date and the related Interest Payment Date, then the interest payable on such Interest Payment Date shall be paid to the Holder of record of the Security on such Regular Record Date. Section 12.02 Conditions to the Company's Election to Pay the Repurchase Price in Common Stock. The Company may elect to pay the Repurchase Price by delivery of shares of Common Stock pursuant to Section 12.01 if and only if the following conditions have been satisfied: (a) The shares of Common Stock deliverable in payment of the repurchase Price shall have a fair market value as of the Repurchase Date of not less than the Repurchase Price. For purposes of this Section 12.02, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices of the Common Stock for the five consecutive Trading Days ending on and including the third Trading Day immediately preceding the Repurchase Dates; (b) The shares of Common Stock deliverable in payment of the Repurchase Price shall be listed for trading on a U.S. national securities exchange or approved for trading on an established automated over-the-counter trading market in the United States, in either case, immediately prior to the repurchase date; and (c) All shares of Common Stock deliverable in payment of the Repurchase Price shall be issued out of the Company's authorized but unissued Common Stock -49- <PAGE> and will, upon issue, be duly and validly issued and fully paid and non- assessable and free of any preemptive rights. If all of the conditions set forth in this Section 12.02 are not satisfied in accordance with the terms thereof, the Repurchase Price shall be paid by the Company only in cash. Section 12.03 Notices; Method of Exercising Repurchase Right, Etc. (a) Unless the Company shall have theretofore called for redemption all of the Outstanding Securities, on or before the 15th day after the occurrence of a Change in Control, the Company or, at the written request of the Company, on or before the tenth (10th) day after receipt of such request, the Trustee, at the Company's expense, shall give notice to all Holders of the Securities (the "Company Notice") of the occurrence of the Change in Control and of the repurchase right set forth herein arising as a result thereof. If the Company gives such notice of a repurchase right, the Company shall also deliver a copy of such notice of a repurchase right to the Trustee. Each Company Notice shall state: (i) the date of such Change in Control and, briefly, the events causing such Change in Control; (ii) the date by which the Change in Control Purchase Notice (as defined below) must be delivered; (iii) the Repurchase Date; (iv) the Repurchase Price, and whether the Repurchase Price shall be paid by the Company in cash or by delivery of shares of Common Stock; (v) a description of the procedure which a Holder must follow to exercise a repurchase right; (vi) the procedures for withdrawing a Change in Control Purchase Notice; (vii) the place or places where such Securities are to be surrendered for payment of the Repurchase Price and accrued interest, if any; (viii) briefly, the conversion rights of Holders of Securities; (ix) the conversion price and any adjustments thereto, the date on which the right to convert the Securities will terminate and the places where such Securities may be surrendered for conversion; (x) that Holders who want to convert Securities must satisfy the requirements set forth in the Securities; and -50- <PAGE> (xi) that no failure of the Company to give the foregoing notice or defect therein shall limit any Holder's right to exercise a repurchase right or affect the validity of the proceedings for the repurchase of the Securities. (b) To exercise a repurchase right, a Holder shall deliver to the Paying Agent or an office or agency maintained by the Company for such purpose in the Borough of Manhattan, The City of New York, prior to the close of business on or before the Repurchase Date written notice of the Holder's exercise of such right (the "Change in Control Purchase Notice"), which notice shall set forth (i) the name of the Holder, the principal amount of the Securities to be repurchased (and, if any Security is to be repurchased in part, the portion of the principal amount thereof to be repurchased and the name of the Person in which the portion thereof to remain outstanding after such repurchase is to be registered) and a statement that an election to exercise the repurchase right is being made thereby pursuant to the applicable provisions of the Securities, and, in the event that the Repurchase Price shall be paid in shares of Common Stock, the name or names (with addresses) in which the certificate or certificates for shares of Common Stock shall be issued, and (ii) the certificate numbers of the Securities with respect to which the repurchase right is being exercised. (c) In the event a repurchase right shall be exercised in accordance with the terms hereof, the Company shall pay or cause to be paid to the Paying Agent the Repurchase Price in cash or shares of Common Stock, as provided above, for payment to the Holder on the Repurchase Date or, if shares of Common Stock are to be issued, with respect to the Securities (or portion thereof) as to which the repurchase right has been exercised; provided, however, that such Security for which a repurchase right has been exercised has been delivered to the Paying Agent at any time after the notice of exercise of a repurchase right shall have been given. Payment of the Repurchase Price for such Security or, if shares of Common Stock are to be issued, shall be made promptly following the later of the Business Day following the Repurchase Date and time of delivery of the Security. If the Paying Agent holds money sufficient to pay the Repurchase Price on the Business Day following the Repurchase Date, then, immediately after the Repurchase Date, such Security shall cease to be outstanding and interest will cease to accrue and will be deemed paid regardless of whether such Security has been delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right of such Holder to receive the Repurchase Price upon delivery of such Security). (d) On or prior to the Repurchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.03 of the Indenture) an amount of money sufficient to pay the Repurchase Price of the Securities which are to be repaid on the Repurchase Date. (e) If any Security (or portion thereof) surrendered for repurchase shall not be so paid on the Business Day following the Repurchase Date, the principal amount of such Security (or portion thereof, as the case may be) shall, until paid, bear interest from the Repurchase Date at the rate of 5 1/2% per annum, and each Security shall remain convertible into -51- <PAGE> Common Stock in accordance with Article 13 herein until the principal of such Security (or portion thereof, as the case may be) shall have been paid or duly provided for. (f) Any Security which is to be repurchased only in part shall be surrendered to the Trustee (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 his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the portion of the principal of the Security so surrendered that was not repurchased. (g) Any Holder that has delivered to the Trustee a Change in Control Purchase Notice shall have the right to withdraw such notice at any time prior to the close of business on the Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent prior to the close of business on such date. The notice of withdrawal shall state the principal amount and the certificate numbers of the Securities as to which the withdrawal notice relates and the principal amount, if any, which remains subject to the notice of exercise of a repurchase right. A Security in respect of which a Holder has exercised its option to require repurchase upon a Change in Control may thereafter be converted into Common Stock only if such Holder withdraws its notice in accordance with the preceding sentence. (h) Any issuance of shares of Common Stock in respect of the Repurchase Price shall be deemed to have been effected immediately prior to the close of business on the Repurchase Date and the person or persons in whose name or names any certificate or certificates for shares of Common Stock shall be issuable upon such repurchase shall be deemed to have become on the Repurchase Date the holder or holders of record of the shares represented thereby; provided, however, that any surrender for repurchase on a date when the stock transfer books of the Company shall be closed shall constitute the person or persons in whose name or names the certificate or certificates for such shares are to be issued as the record holder or holders thereof for all purposes at the opening of business on the next succeeding day on which such stock transfer books are open. No payment or adjustment shall be made for dividends or distributions on any Common Stock issued upon repurchase of any Security declared prior to the Repurchase Date. (i) No fractional shares of Common Stock or scrip representing fractional shares shall be issued upon repurchase of Securities. If more than one Security shall be repurchased from the same holder and the Repurchase Price shall be payable in shares of Common Stock, the number of full shares which shall be issued upon repurchase shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so repurchased. If any fractional share of stock otherwise would be issuable upon repurchase of any Security or Securities, the Company shall make an adjustment therefor in cash at the current market value thereof to the Holder of Securities. For -52- <PAGE> these purposes, the current market value of a share of Common Stock shall be the Closing Price on the first Trading Day immediately preceding the Repurchase Date. (j) The issue of stock certificates on repurchase of Securities shall be made without charge to the Holder of Securities being repurchased for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Security repurchased, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. Section 12.04. Certain Definitions. For purposes of this Article 12: (a) the terms "beneficial owner" and "beneficial ownership" shall be determined in accordance with Rules 13d-3 and 13d-5 promulgated by the Commission pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), except that a Person shall be deemed to have "beneficial ownership" of all securities that such Person has the right to acquire, whether such right is exercisable immediately or only after the passage of time; and (b) the term "person" shall include any syndicate or group which would be deemed to be a "Person" under Section 13(d)(3) of the Exchange Act. Section 12.05. Change in Control. A "Change in Control" shall be deemed to have occurred at such time after the original issuance of the Securities as: (a) any "person" or "group" (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act), acquires the beneficial ownership, directly or indirectly, through a purchase, merger or other acquisition transaction, of more than 50% of the Company's total outstanding voting stock other than an acquisition by the Company, any of its Subsidiaries or any of its employee benefit plans. (b) the Company shall consolidate with, or merge with or into another Person or convey, transfer, lease or otherwise dispose of all or substantially all of its assets to any Person, or any Person consolidates with or merges with or into the Company, in any event pursuant to a transaction in which the Company's outstanding voting stock is converted into or exchanged for cash, securities or other property, other than any such transactions where: (i) the Company's voting stock is not converted or exchanged at all (except to the extent necessary to reflect a change in the Company's jurisdiction of incorporation) or is converted into or exchanged for voting stock (other than Redeemable Capital Stock) of the surviving or transferee corporation, and (ii) immediately after such transaction, no "person" or "group" (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act) is the "beneficial -53- <PAGE> owner", directly or indirectly, of more than 50% of the total outstanding voting stock of the surviving or transferee corporation; (c) during any consecutive two-year period, individuals who at the beginning of such period constituted the 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 of whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the Board of Directors then in office; (d) a special resolution is passed by the Company's stockholders approving the plan of liquidation or dissolution other than in a transaction which complies with the provisions described in Article 8 of the Indenture. "Redeemable Capital Stock" means any class of series of capital stock that, either by its terms, by the terms of any security into which it is convertible or exchangeable or by contract or otherwise, is, or upon the happening of an event or passage of time would be, required to be redeemed prior to the final stated maturity of the Securities or is redeemable at the option of the holder thereof at any time prior to such final stated maturity, or is convertible into or exchangeable for debt securities at any time prior to such final stated maturity; provided, however, that Redeemable Capital Stock shall not include any common stock the holder of which has the right to put to the Company upon certain terminations of employment. Section 12.06. References to Repurchase Price. Whenever in this Indenture there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Indenture shall not be construed as excluding the Repurchase Price in those provisions of this Indenture when such express mention is not made; provided, however, that for the purposes of this Article 12, such reference shall be deemed to include reference to the Repurchase Price only if the Repurchase Price is payable in cash. ARTICLE XIII Conversion Section 13.01. Conversion Privilege and Conversion Price. Subject to and upon compliance with the provisions of this Article 13, at the option of the Holder thereof, any Security 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 fully paid and nonassessable shares of Common Stock of the Company (the "Conversion Shares") at any time following the date of original issuance of Securities at the conversion price, determined -54- <PAGE> as hereinafter provided, in effect at the time of conversion. Such conversion right shall expire at the close of business on December 21, 2004, subject to any rules and procedures of the depositary for such security in effect from time to time (the "Applicable Procedures"). In case a Security or portion thereof has previously been called for redemption at the election of the Company, such conversion right in respect of the Security or portion so called shall expire at the close of business, New York City time, on the Redemption Date, unless the Company defaults in making the payment due upon redemption (in each case subject as aforesaid to any Applicable Procedures). A Security in respect of which a Holder has delivered a Change in Control Purchase Notice (as defined in Article 12 hereof) exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice is withdrawn by a written notice of withdrawal delivered by the Holder to the Paying Agent prior to the close of business on the Repurchase Date, in accordance with the terms of this Indenture. The price at which shares of Common Stock shall be delivered upon conversion (herein called the "conversion price") shall be initially $127.44 per share of Common Stock, which is equal to a conversion rate of 7.8468 shares per $1,000 principal amount of the Securities (the "Conversion Rate"). The conversion price shall be adjusted in certain instances as provided in Section 13.04. In case the Company shall, by dividend or otherwise, declare or make a distribution on its Common Stock referred to in Section 13.04(d) or 13.04(e) (including dividends or distributions referred to in the last sentence of Section 13.04(d)), the Holder of each Security, upon the conversion thereof pursuant to this Article 13 subsequent to the close of business on the date fixed for the determination of stockholders entitled to receive such distribution and prior to the effectiveness of the conversion price adjustment in respect of such distribution pursuant to Section 13.04(d) or 13.04(e), shall also be entitled to receive for each share of Common Stock into which such Security is converted, the portion of the evidences of indebtedness, shares of capital stock, securities, cash and other property so distributed applicable to one share of Common Stock; provided, however, that, at the election of the Company (whose election shall be evidenced by a Board Resolution) with respect to all Holders so converting, the Company may, in lieu of distributing to such Holder any portion of such distribution not consisting of cash or securities of the Company, pay such Holder an amount in cash equal to the fair market value thereof (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution). If any conversion of a Security described in the immediately preceding sentence occurs prior to the payment date for a distribution to holders of Common Stock which the Holder of the Security so converted is entitled to receive in accordance with the immediately preceding sentence, the Company may elect (such election to be evidenced by a Board Resolution) to distribute to such Holder a due bill for the evidences of indebtedness, shares of capital stock, securities, cash or assets to which such Holder is so entitled; provided that such due bill (i) meets any applicable requirements of the principal national securities exchange or other market on which the Common Stock is then traded and (ii) requires payment or delivery of such evidences of indebtedness, shares of capital stock, securities, cash or assets no later than the date of payment or delivery thereof to holders of Common Stock receiving such distribution. -55- <PAGE> Section 13.02. Exercise of Conversion Privilege. In order to exercise the conversion privilege, the Holder of any Security to be converted shall surrender such Security, duly endorsed or assigned to the Company or in blank, at any office or agency maintained by the Company pursuant to Section 10.02 of this Indenture, accompanied by (a) written notice to the Company in substantially the form of conversion notice attached to the form of Security attached as Exhibit A hereto at such office or agency that the Holder elects to convert such Security or, if less than the entire principal amount thereof is to be converted, the portion thereof to be converted and (b) if shares or any portion of such Security not to be converted are to be issued in the name of a Person other than the Holder thereof, the name of the Person in which to issue such shares. Except as provided in Section 5.02 of this Indenture, no Holder of Security will be entitled upon conversion thereof to any payment or adjustment on account of accrued and unpaid interest thereon or on account of dividends on the shares of Common Stock issued in connection therewith. Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date (except Securities or a portion thereof being converted that shall have been called for redemption on a Redemption Date during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date) must be accompanied by payment to the Company in immediately available funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount converted. Securities shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Securities for conversion in accordance with the foregoing provisions (the "Conversion Date"), and at such time the rights of the Holders of such Securities as Holders shall cease, and the Person or Persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock at such time. As promptly as practicable on or after the Conversion Date, but in any event no later than the seventh Business Day following the Conversion Date, the Company shall issue and shall deliver at such office or agency a certificate or certificates for the number of full shares of Common Stock issuable upon conversion, together with payment in lieu of any fraction of a share as provided in Section 13.03. In the case of any Security 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 Security or Securities of authorized denominations in aggregate principal amount equal to the unconverted portion of the principal amount of such Security. Any requirements for notice, surrender or delivery of Securities pursuant to this Article 13 shall be subject to any Applicable Procedures. Section 13.03. Fractions of Shares. No fractional shares of Common Stock shall be issued upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable -56- <PAGE> upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof) so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Security (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the Closing Price per share of the Common Stock at the close of business on the Trading Day immediately preceding such day or, alternatively, the Company shall round up to the next higher whole share. "Trading Day" shall mean each day on which the primary securities exchange or quotation system which is used to determine the Closing Price is open for trading or quotation. "Closing Price" of a single share of Common Stock on any Trading Day shall mean the closing sale price per share for the Common Stock (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 prices and the average ask prices) on such Trading Day as reported in composite transactions for the principal United States securities exchange on which the Common Stock is traded or, if the Common Stock is not listed on a United States national or regional stock exchange, as reported by the National Association of Securities Dealers Automated Quotation System. Section 13.04. Adjustment of Conversion Price. (a) In case the Company shall pay or make a dividend or other distribution on its Common Stock exclusively in Common Stock, the conversion price in effect at the opening of business on the day next following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination and the denominator shall be the sum of such number of shares and the total number of shares constituting such dividend or other distribution, such reduction to become effective immediately after the opening of business on the day next following the date fixed for such determination. For the purposes of this Section 13.04(a), 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 shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (b) In case the Company shall pay or make a dividend or other distribution on its Common Stock consisting exclusively of, or shall otherwise issue to all holders of its Common Stock, rights, warrants or options entitling the holders thereof, for a period not exceeding 45 days, to subscribe for or purchase shares of Common Stock at a price per share less than the current market price per share (determined as provided in Section 13.04(g)) of the Common Stock on the date fixed for the determination of stockholders entitled to receive such rights, warrants or options, the conversion price in effect at the opening of business on the day following the date fixed for such determination shall be reduced by multiplying such conversion price by a fraction of which the numerator shall be the number of -57- <PAGE> shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock which the aggregate of the offering price of the total number of shares of Common Stock so offered for subscription or purchase would purchase at such current market price and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription or purchase, such reduction to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this Section 13.04(b), 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 shall not issue any rights, warrants or options in respect of shares of Common Stock held in the treasury of the Company. (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately reduced, and, conversely, in case outstanding shares of Common Stock shall each be combined into a smaller number of shares of Common Stock, the conversion price in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately increased, such reduction or increase, 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. (d) Subject to the last sentence of this Section 13.04(d), in case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness, shares of any class of capital stock, securities, cash or property (excluding any rights, warrants or options referred to in Section 13.04(b), any dividend or distribution paid exclusively in cash and any dividend or distribution referred to in Section 13.04(a)), the conversion price shall be reduced so that the same shall equal the price determined by multiplying the conversion price in effect immediately prior to the effectiveness of the conversion price reduction contemplated by this Section 13.04(d) by a fraction of which the numerator shall be the current market price per share (determined as provided in Section 13.04(g)) of the Common Stock on the date of such effectiveness less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution and shall, in the case of securities being distributed for which prior thereto there is an actual or when issued trading market, be no less than the value determined by reference to the average of the Closing Prices in such market over the period specified in the succeeding sentence), on the date of such effectiveness, of the portion of the evidences of indebtedness, shares of capital stock, securities, cash and property so distributed applicable to one share of Common Stock and the denominator shall be such current market price per share of the Common Stock, such reduction to become effective immediately prior to the opening of business on the day next following the later of (i) the date fixed for the payment of such distribution and (ii) the date 20 days after the notice relating to such distribution is given pursuant to Section 13.06 (such later date of (i) and (ii) being referred to as the "Reference -58- <PAGE> Date"). The provisions of this Section 13.04(d) shall not be applicable to an event covered by Section 13.04(j) or a Rights IPO or any other public offering by a Partner Company (as defined in Section 13.04(k)) that includes a Directed Share Subscription Program (as defined in Section 13.04(k)). If the Board of Directors determines the fair market value of any distribution for purposes of this Section 13.04(d) by reference to the actual or when issued trading market for any securities comprising such distribution, it must in doing so consider the prices in such market over the same period used in computing the current market price per share pursuant to Section 13.04(g). For purposes of this Section 13.04(d), any dividend or distribution that includes shares of Common Stock or rights, warrants or options to subscribe for or purchase shares of Common Stock shall be deemed instead to be (A) a dividend or distribution of the evidences of indebtedness, cash, property, shares of capital stock or securities other than such shares of Common Stock or such rights, warrants or options (making any conversion price reduction required by this Section 13.04(d)) immediately followed by (B) a dividend or distribution of such shares of Common Stock or such rights (making any further conversion price reduction required by Sections 13.04(a) or 13.04(b)), except (1) the Reference Date of such dividend or distribution as defined in this Section 13.04(d) shall be substituted as "the date fixed for the determination of stockholders entitled to receive such dividend or other distributions," "the date fixed for the determination of stockholders entitled to receive such rights, warrants or options" and "the date fixed for such determination" within the meaning of Sections 13.04(a) and 13.04(b) and (2) 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 this Section 13.04(b). (e) In case the Company shall, by dividend or otherwise, make a distribution to all holders of its Common Stock exclusively in cash in an aggregate amount that, together with (i) the aggregate amount of any other distributions to all holders of its Common Stock made exclusively in cash within the 12 months preceding the date of payment of such distribution and in respect of which no conversion price adjustment pursuant to this Section 13.04(e) has been made and (ii) the aggregate of any cash plus the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of the tender or exchange offer referred to below, of consideration payable in respect of any tender or exchange offer by the Company or a Subsidiary for all or any portion of the Common Stock concluded within the 12 months preceding the date of payment of such distribution and in respect of which no conversion price adjustment pursuant to this Section 13.04(f) has been made, exceeds 10% of the product of the current market price per share (determined as provided in this Section 13.04(g)) of the Common Stock as of the Trading Day immediately preceding the record date fixed for stockholders entitled to receive such distribution times the number of shares of Common Stock outstanding on such record date, the conversion price shall be reduced so that the same shall equal the price determined by multiplying the conversion price in effect immediately prior to the effectiveness of the conversion price reduction contemplated by this Section 13.04(e) by a fraction of which the numerator shall be the current market price per share (determined as provided in this Section 13.04(e) of the Common Stock on the date of such effectiveness less an amount equal to the quotient of (x) the excess of such combined amount over such 10% and (y) the number of shares -59- <PAGE> of Common Stock outstanding on the record date and (iii) the denominator of which shall be equal to the current market price on such record date, such reduction to become effective immediately prior to the opening of business on the later of (a) the day following the record date fixed for the payment of such distribution and (b) the date 20 days after the notice relating to such distribution is given pursuant to Section 13.06. (f) In case a successful tender or exchange offer, other than an odd lot offer, made by the Company or any Subsidiary for all or any portion of the Common Stock shall involve an aggregate consideration having a fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution) at the last time (the "Expiration Time") tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) that, together with (i) the aggregate of the cash plus the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a Board Resolution), as of the expiration of the other tender or exchange offer referred to below, of consideration payable in respect of any other tender or exchange offer by the Company or a Subsidiary for all or any portion of the Common Stock concluded within the preceding 12 months and in respect of which no conversion price adjustment pursuant to this Section 13.04(f) has been made and (ii) the aggregate amount of any distributions to all holders of the Common Stock made exclusively in cash within the preceding 12 months and in respect of which no conversion price adjustment pursuant to Section 13.04(e) has been made, exceeds 10% of the product of the current market price per share (determined as provided in Section 13.04(g)) of the Common Stock outstanding (including any tendered shares) on the Expiration Time, the conversion price shall be reduced (but not increased) so that the same shall equal the price determined by multiplying the conversion price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be (i) the product of the current market price per share (determined as provided in Section 13.04(g)) of the Common Stock on the Trading Day next succeeding the Expiration Time times the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time minus (ii) 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 or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and the denominator shall be the product of (i) such current market price per share on the Trading Day next succeeding the Expiration Time times (ii) such number of outstanding shares at the Expiration Time less the number of Purchased Shares, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Time. (g) For the purpose of any computation under this Section 13.04(g) and Sections 13.04(b),(d) and (e), the current market price per share of Common Stock on any date in question shall be deemed to be 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 (i) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the -60- <PAGE> conversion price pursuant to Section 13.04(a), (b), (c), (d), (e) or (f) ("Other Event") occurs on or after the 20th Trading Day prior to the date in question and prior to the "ex" date for the issuance or distribution requiring such computation (the "Current Event"), 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 same fraction by which the conversion price is so required to be adjusted as a result of such Other Event, (ii) if the "ex" date for any Other Event occurs after the "ex" date for the Current Event and on or prior to the date 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 reciprocal of the fraction by which the conversion price is so required to be adjusted as a result of such Other Event, (iii) if the "ex" date for any Other Event occurs on the "ex" date for the Current Event, one of those events shall be deemed for purposes of clauses (i) and (ii) of this proviso to have an "ex" date occurring prior to the "ex" date for the Other Event, and (iv) if the "ex" date for the Current Event is on or prior to the date in question, after taking into account any adjustment required pursuant to clause (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 on the date in question (as determined in good faith by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 13.04(d) or (e), whose determination shall be conclusive and described in a Board Resolution) of the portion of the rights, warrants, options, evidences of indebtedness, shares of capital stock, securities, cash or property being distributed applicable to one share of Common Stock. For the purpose of any computation under this Section 13.04(f), the current market price per share of Common Stock on any date in question shall be deemed to be the average of the daily Closing Prices for the 5 consecutive Trading Days selected by the Company commencing on or after the latest (the "Commencement Date") of (i) the date 20 Trading Days before the date in question, (ii) the date of commencement of the tender or exchange offer requiring such computation and (iii) the date of the last amendment, if any, of such tender or exchange offer involving a change in the maximum number of shares for which tenders are sought or a change in the consideration offered, and ending not later than the Trading Day next succeeding the Expiration Time of such tender or exchange offer (or, if such Expiration Time occurs before the close of trading on a Trading Day, not later than the Trading Day during which the Expiration Time occurs); provided, however, that if the "ex" date for any Other Event (other than the tender or exchange offer requiring such computation) occurs on or after the Commencement Date and on or prior to the Trading Day next succeeding the Expiration Time for the tender or exchange offer requiring such computation, 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 same fraction by which the conversion price is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, (i) when used 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, (ii) when used 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 (iii) when used with respect to any -61- <PAGE> 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 tender or exchange offer. (h) The Company may make such reductions in the conversion price, in addition to those required by paragraphs (a), (b), (c), (d), (e) and (f) of this Section 13.04, as it considers to be advisable in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients, or to diminish the amount of such tax payable. (i) No adjustment in the conversion price shall be required unless such adjustment would require an increase or decrease of at least 1% in the conversion price; provided, however, that any adjustments which by reason of this Section 13.04(i) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. (j) In the event that the Company distributes assets, debt securities, rights, warrants or options (other than those referred to in Section 13.04(b) above) pro rata to holders of Common Stock, and the fair market value of the portion of assets, debt securities, rights, warrants or options applicable to one share of Common Stock distributed to holders of Common Stock exceeds the Average Sale Price (as defined below) per share of Common Stock, or such Average Sale Price exceeds such fair market value by less than $1.00, then so long as any such assets, debt securities, rights, options or warrants have not expired or been redeemed by the Company, the Company shall make proper provision so that the Holder of any Security upon conversion, rather than being entitled to an adjustment in the conversion price, will be entitled to receive upon such conversion, in addition to the Conversion Shares, a number of assets, debt securities, rights, warrants and options to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of assets, debt securities, rights, warrants or options of separate certificates evidencing such assets, debt securities, rights, warrants or options (the "Distribution Date"), the same number of assets, debt securities, rights, warrants or options to which a holder of a number of shares of Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions of and applicable to the assets, debt securities, rights, warrants or options being distributed, and (ii) if such conversion occurs after such Distribution Date, the same number of assets, debt securities, rights, warrants or options to which a holder of the number of shares of Common Stock into which the principal amount of such Security so converted was convertible immediately prior to such Distribution Date would have been entitled on such Distribution Date in accordance with the terms and provisions of and applicable to the assets, debt securities, rights, warrants or options. "Average Sale Price" means the average of the Closing Prices of the Common Stock for the shorter of (i) 30 consecutive Trading Days ending on the last full Trading Day prior to the Time of Determination (as defined below) with respect to the rights, options, warrants or distribution in respect of which the Average Sale Price is being calculated, or (ii) the period (x) commencing on the date next succeeding the first public announcement of (a) the issuance of -62- <PAGE> rights, options or warrants or (b) the distribution, in each case, in respect of which the Average Sale Price is being calculated and (y) proceeding through the last full Trading Day prior to the Time of Determination with respect to the rights, options, warrants or distribution in respect of which the Average Sale Price is being calculated, or (iii) the period, if any, (x) commencing on the date next succeeding the Ex-Dividend Time (as defined below) with respect to the next preceding (a) issuance of rights, warrants or options or (b) distribution, in each case, for which an adjustment is required by the provisions of Section 13.04(b) or Section 13.04(j) and (y) proceeding through the last full Trading Day prior to the Time of Determination with respect to the rights, options, warrants, or distribution in respect of which the Average Sale Price is being calculated. If the Ex-Dividend Time (or in the case of a subdivision, combination or reclassification, the effective date with respect thereto) with respect to a dividend, subdivision, combination or reclassification to which Section 13.04(a) or (b) applies occurs during the period applicable for calculating "Average Sale Price" pursuant to the definition in the preceding sentence, "Average Sale Price" shall be calculated for such period in a manner determined in good faith by the Board of Directors to reflect the impact of such dividend, subdivision, combination or reclassification on the Closing Price of the Common Stock during such period. "Time of Determination" means the time and date of the earlier of (i) the determination of stockholders entitled to receive rights, warrants or options or a distribution, in each case, to which this Section 13.04(j) applies and (ii) the time ("Ex-Dividend Time") immediately prior to the commencement of "ex-dividend" trading for such rights, options, warrants or distribution on the New York Stock Exchange or such other national or regional exchange or market on which the shares of Common Stock are listed or quoted. (k) (i) In case a Partner Company shall issue rights ("IPO Rights") in a Rights IPO, effective on the date of such Partner Company's initial public offering (the "Relevant Closing Date"), the conversion price on the date immediately following the Relevant Closing Date shall be obtained by making the following adjustment calculation: (A) dividing the average closing price of the IPO Rights on the last ten trading days that the IPO Rights were publicly traded, by the number of shares of Common Stock that are required, under the terms of the IPO Rights, to allow a holder of Common Stock to receive one IPO Right (the "Rights Value Per Share"), then (B) multiplying (1) the Rights Value Per Share by (2) the principal amount of each Security divided by the conversion price in effect on the last day (the "Expiration Date") that the IPO Rights are publicly traded (the "Original Conversion Ratio" and the product of such function, the "Rights Value Per Security"), then (C) dividing (1) the Rights Value Per Security by (2) the Closing Price for the Company's Common Stock on the Expiration Date minus the Rights Value per Share, and then -63- <PAGE> (D) dividing (1) the principal amount of each Security by (2) the sum of (C) plus the Original Conversion Ratio. Any adjustment shall be successively made whenever any Rights IPO is completed, and shall become effective on the Business Day following the closing of a Rights IPO. (ii) In case a Partner Company shall undertake, as part of the initial public offering of its common stock pursuant to a registration statement filed on Form S-1 under the Securities Act that includes a Directed Share Subscription Program, the conversion price shall be subject to the following adjustment: (A) dividing the difference (if any, and in each case only where (1) is a higher number than (2) between (1) the average closing or last sale prices, as applicable, of the common stock of that Partner Company on the first four days its common stock is publicly traded and (2) the initial public offering price of its common stock, by (3) the number of shares of the Company's Common Stock required to subscribe for one share of common stock of that Partner Company (the "Subscription Value per Share"), then (B) multiplying (1) the Subscription Value per Share by (2) the principal amount of each Security divided by the conversion price in effect on the fourth day that the common stock of the Partner Company was publicly traded (the "Relevant Conversion Ratio"), the product of such calculation being the "Subscription Value per Security", then (C) taking the Subscription Value per Security and dividing by the Conversion Price in effect immediately prior to the adjustment made hereunder, and then (D) dividing (1) the principal amount of each Security by (2) the sum of (C) plus the Relevant Conversion Ratio. Any adjustment shall be successively made whenever a Partner Company completes an initial public offering which includes a Directed Share Subscription Program, if any, and will be effective on the fifth Business Day following the Relevant Closing Date. "Rights IPO" means an initial public offering of the common stock of a Partner Company solely through the issuance of rights, by such Partner Company, to purchase such common stock to the shareholders of the Company. "Directed Share Subscription Program" means a program whereby all shareholders of the Company are entitled to purchase a portion of the shares offered by a Partner Company in that Partner Company's initial public offering. -64- <PAGE> Section 13.05 Notice of Adjustments of Conversion Price. Whenever the conversion price is adjusted as herein provided: the Company shall compute the adjusted conversion price in accordance with Section 13.04 and shall prepare a certificate signed by the Chief Financial Officer of the Company setting forth the adjusted conversion price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed (with a copy to the Trustee) at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.02 of the Indenture; and Section 13.06 Notice of Certain Corporate Action. In case: (a) the Company shall declare a dividend (or any other distribution) on its Common Stock that would require a conversion price adjustment pursuant to Section 13.04(e); or (b) the Company shall authorize the granting to all holders of its Common Stock of rights, warrants or options to subscribe for or purchase any shares of capital stock of any class or of any other rights (excluding rights distributed pursuant to any stockholder rights plan); or (c) of any reclassification of the Common Stock of the Company (other than a subdivision or combination of its outstanding shares of Common Stock), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) of the voluntary or involuntary dissolution, liquidation or winding, up of the Company; or (e) the Company or any Subsidiary of the Company shall commence a tender or exchange offer for all or a portion of the Company's outstanding shares of Common Stock (or shall amend any such tender or exchange offer); then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of Securities pursuant to Section 10.02 of the Indenture, and shall cause to be mailed to all Holders at their last addresses as they shall appear in the Security Register, at least 20 days (or 10 days in any case specified in clause 13.06(a) or 13.06(b) above) prior to the applicable record, effective or expiration date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or granting of rights, warrants or options, 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, warrants or options are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, 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, consolidation, merger, sale, transfer, dissolution, liquidation or winding up, or (z) the date on -65- <PAGE> which such tender offer commenced, the date on which such tender offer is scheduled to expire unless extended, the consideration offered and the other material terms thereof (or the material terms of any amendment thereto). Section 13.07 Company's Obligation Regarding Common Stock. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of Securities, the whole number of shares of Common Stock then issuable upon the conversion in full of all outstanding Securities. Before taking any action which would cause an adjustment reducing the conversion price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted conversion price. The Company covenants that if any shares of Common Stock to be provided for the purpose of conversion of Securities hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as practicable endeavor to secure such registration or approval, as the case may be. The Company further covenants that so long as the Common Stock shall be listed or quoted on the New York Stock Exchange, the Nasdaq Stock Market (National Market), or any other national securities exchange the Company will, if permitted by the rules of such exchange, list and keep listed so long as the Common Stock shall be so listed on such market or exchange, all Common Stock issuable upon conversion of the Securities. Section 13.08 Taxes on Conversions. The Company will pay any and all taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Securities pursuant hereto. The Company shall not, however, be required to pay any tax 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 Security or Securities to be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid. Section 13.09 Covenant as to Common Stock. The Company covenants that all shares of Common Stock which may be issued upon conversion of Securities shall upon issue be newly issued (and not treasury shares) and be duly authorized, validly issued, fully paid and nonassessable and, except as provided in Section 13.07, the Company shall pay all taxes, liens and charges with respect to the issue thereof. -66- <PAGE> Section 13.10 Cancellation of Converted Securities. All Securities delivered for conversion shall be delivered to the Trustee to be cancelled by or at the direction of the Trustee, which shall dispose of the same as provided in Section 3.08 of this Indenture. Section 13.11 Provisions in Case of Reclassification, Consolidation, Merger or Sale of Assets. In the event that the Company shall be a party to any transaction (including any (i) recapitalization or reclassification of the 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 of the Common Stock), (ii) any consolidation of the Company with, or merger of the Company into, any other person, any merger of another person into the Company (other than a merger which does not result in a reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock of the Company), (iii) any sale or transfer of all or substantially all of the assets of the Company or (iv) any compulsory share exchange) pursuant to which the Common Stock is converted into the right to receive other securities, cash or other property, then lawful provision shall be made as part of the terms of such transaction whereby the Holder of each Security then Outstanding shall have the right thereafter to convert such Security only into (subject to funds being legally available for such purpose under applicable law at the time of such conversion) the kind and amount of securities, cash and other property receivable upon such transaction by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such transaction. The Company or the person formed by such consolidation or resulting from such merger or which acquired such assets or which acquired the Company's shares of Common Stock, as the case may be, shall execute and deliver to the Trustee a supplemental indenture establishing such rights. Such supplemental indenture shall provide for adjustments which, for events subsequent to the effective date of such supplemental indenture, shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article. The above provisions of this Section 13.11 shall similarly apply to successive transactions of the foregoing type. Section 13.12 Company's Obligation. All calculations, adjustments, conversions and other determinations under this Article 13 shall be the sole responsibility and obligation of the Company. The Trustee (a) shall have no obligation to review, challenge or contest any such calculation, adjustment, conversion or other determination and (b) shall not be liable for any default or error by the Company under this Article 13. ARTICLE XIV Subordination Section 14.01 Securities Subordinate to Senior Indebtedness. The Company covenants and agrees, and each Holder of Securities, by such Holder's acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article 14, the indebtedness represented by the Securities and the payment of the principal of (and premium, if any), and interest on and all other amounts payable under each and all of the Securities including, but not limited to, the Redemption Prices, the Make-Whole Payment and the -67- <PAGE> Repurchase Price payable with respect to the Securities in accordance with Article 11 or Article 12, as the case may be, and all obligations of the Company under the Indenture are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness. Section 14.02 Payment over of Proceeds upon Dissolution, Etc. In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding-up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshaling of assets and liabilities of the Company, then and in any such event the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness, or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Indebtedness, before the Holders of the Securities are entitled to receive any payment on account of principal of (or premium, if any), or interest on or any other amount payable under the Securities, including, but not limited to, the Redemption Prices, the Make-Whole Payment and the Repurchase Price payable with respect to the Securities in accordance with Article 11 or Article 12, as the case may be, and to that end the holders of Senior Indebtedness shall be entitled to receive, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, which may be payable or deliverable in respect of the Securities in any such case, proceeding, dissolution, liquidation or other winding-up or event. In the event that, notwithstanding the foregoing provisions of this Section 14.02, the Trustee or the Holder of Securities shall have received any payment or distribution of assets of the Company prohibited by the foregoing paragraph of any kind or character, whether in cash, property or securities, before all Senior Indebtedness is paid in full or payment thereof provided for, and if, at or prior to the time of such payment or distribution, written notice that such payment or distribution is prohibited by the foregoing paragraph shall have been actually given to a Responsible Officer of the Trustee or, as the case may be, such Holder, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness. For purposes of this Article 14 only, the words "cash, property or securities" shall not be deemed to include shares of capital stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment which in either case are subordinated in right of payment to all Senior Indebtedness which may at the time be outstanding to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article 14. The -68- <PAGE> consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or transfer of its properties and assets substantially as an entirety to another Person upon the terms and conditions set forth in Article 8 shall not be deemed a dissolution, winding-up, liquidation, reorganization, assignment for the benefit of creditors or marshaling of assets and liabilities of the Company for the purposes of this Section 14.02 if the Person formed by such consolidation or into which the Company is merged or which acquires by conveyance or transfer such properties and assets substantially as an entirety, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article 8. Section 14.03 No Payment When Senior Indebtedness in Default. (a) In the event and during the continuation of any default in the payment of principal of (or premium, if any) or interest on any Senior Indebtedness beyond any applicable grace period with respect thereto (unless and until such payment default shall have been cured or waived in writing by the holders of such Senior Indebtedness), or (b) any default (other than a payment default) with respect to Senior Indebtedness occurs and is continuing that permits the acceleration of the maturity thereof and judicial proceedings shall be pending with respect to any such default or the Company receives written notice of such default (a "Senior Indebtedness Default Notice"), then no payment shall be made by the Company on account of principal of (or premium, if any) or interest on the Securities or on account of the redemption, purchase or other acquisition of Securities (including pursuant to Articles 2, 11, 12 and 13). Notwithstanding the foregoing, payments with respect to the Securities may resume and the Company may acquire Securities for cash when (x) the default with respect to the Senior Indebtedness is cured or waived or ceases to exist or (y) in the case of a default described in (b) above, 179 or more days pass after the Senior Indebtedness Default Notice is received by the Company; provided, that the terms of this Indenture otherwise permit the payment or acquisition of the Securities at that time. If the Company receives a Senior Indebtedness Default Notice, then a similar notice received within nine months thereafter relating to the same default on the same issue of Senior Indebtedness shall not be effective to prevent the payment or acquisition of the Securities as described in the first sentence of this Section 14.03(a). In addition, no payment may be made on the Securities if any Securities are declared due and payable prior to their Stated Maturity by reason of the occurrence of an Event of Default until the earlier of (i) 120 days after the date of such acceleration or (ii) the payment in full of all Senior Indebtedness, but only if such payment is then otherwise permitted under the terms of this Indenture. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of Securities prohibited by the foregoing provisions of this Section 14.03, and if, at or prior to the time of such payment, written notice that such payment is prohibited by the foregoing paragraph shall have been actually given to a Responsible Officer of the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over and delivered forthwith to the Company. The provisions of this Section 14.03 shall not apply to any payment with respect to which Section 14.02 would be applicable. -69- <PAGE> Section 14.04 Payment Permitted If No Default.

Section 14.05 Subrogation to Rights of Holders of Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness, and until the Securities are paid in full, the Holders of the Securities shall be subrogated (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to indebtedness of the Company to substantially the same extent as the Securities are subordinated and is entitled to like rights of subrogation) to the rights of the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness to the extent that payments and distributions otherwise payable to Holders of Securities have been applied to the payment of Senior Indebtedness as provided by this Article 14. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled, except for the provisions of this Article 14, and no payments over pursuant to the provisions of this Article 14 to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness. Section 14.06 Provisions Solely to Define Relative Rights. The provisions of this Article 14 are and are intended solely for the purpose of defining the relative rights of the Holders of the Securities on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article 14 or elsewhere herein or in the Securities is intended to or shall: (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights under this Article 14 of the holders of Senior Indebtedness, is intended to rank equally with all other general obligations of the Company), to pay to the Holders of the Securities the principal of (and premium, if any), and -70- <PAGE> interest on, and any other amount payable under the Securities including, but not limited to, the Redemption Prices and the Repurchase Price payable with respect to the Securities in accordance with Article 11 and Article 12, respectively, as and when the same shall become due and payable in accordance with their terms; (b) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Securities from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 14 of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder. Section 14.07 Trustee to Effectuate Subordination. Each Holder of Securities by its acceptance thereof authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 14 and appoints the Trustee its attorney-in-fact for any and all such purposes. Section 14.08 No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article 14 or the obligations hereunder of the Holders of the Securities to the holders of Senior Indebtedness, do any one or more of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (c) release any Person liable in any manner for the collection of Senior Indebtedness; (d) exercise or refrain from exercising any rights against the Company and any other Person; -71- <PAGE> (e) apply any and all sums received from time to time to the Senior Indebtedness. Section 14.09 Notice to Trustee. The Company shall give prompt written notice to the Trustee if, to the Company's knowledge, any payment to or by the Trustee in respect of the Securities is prohibited by this Article 14. Notwithstanding the provisions of this Article 14 or any other provision of this Indenture, the Trustee shall not be charged with knowledge that any payment to or by the Trustee in respect of the Securities is prohibited by this Article 14, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or a holder of Senior Indebtedness or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 1.04, shall be entitled in all respects to assume that no facts exist that would prohibit any payment in respect of the Securities; provided, however, that if a Responsible Officer of the Trustee shall not have received the notice provided for in this Section 14.09 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including the payment of the principal of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such date. Subject to the provisions of Article 6, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing itself to be a holder of Senior Indebtedness (or a trustee therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 14, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 14, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. Section 14.10 Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred to in this Article 14, the Trustee, subject to the provisions of Article 6, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof -72- <PAGE> or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 14. Section 14.11 Trustee Not Fiduciary for Holders of Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 14 or otherwise. Section 14.12 Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee's Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 14 with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 14 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.07. Section 14.13 Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article 14 shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article 14 in addition to or in place of the Trustee; provided, however, that Section 14.12 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. Section 14.14 Certain Conversions Deemed Payment. For the purposes of this Article 14 only, (1) the issuance and delivery of junior securities upon conversion of Securities in accordance with Article 13 shall not be deemed to constitute a payment or distribution on account of the principal of or premium or interest on Securities or on account of the redemption, purchase or other acquisition of Securities, and (2) the payment, issuance or delivery of cash, property or securities (other than junior securities) upon conversion of a Security shall be deemed to constitute payment on account of the principal of such Security. For the purposes of this Section 14.14, the term "junior securities" means (a) shares of any stock of any class of the Company and (b) securities of the Company which are subordinated in right of payment to the prior payment in full of all Senior Indebtedness which may be outstanding at the time of issuance or delivery of such securities to substantially the same extent as, or to a greater extent than, the Securities are so subordinated as provided in this Article 14. Nothing contained in this Article 14 or elsewhere in this Indenture or in the Securities is intended to or shall impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Securities, the right, which is absolute and unconditional, of the Holder of any Security to convert such Security in accordance with Article 13. -73- <PAGE> IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed all as of the day and year first above written.

Dated: Chase Manhattan Trust Company, National Association as Trustee By: _______________________________ Name: Title: [FORM OF REVERSE OF SECURITY] Internet Capital Group, Inc. 5 1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2004 This Security is one of a duly authorized issue of Securities of the Company designated as its 5 1/2% Convertible Subordinated Notes due 2004 (herein called the "Securities"), limited in aggregate principal amount to $566,250,000, issued and to be issued under an Indenture, dated as of December 21, 1999 (the "Indenture"), between the Company and Chase Manhattan Trust Company, National Association, as Trustee for the Holders of Securities issued under said Indenture (herein called the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Indebtedness and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at its option, at any time on or before maturity of the Securities, or in case this Security or a portion hereof is called for redemption, then in respect of this Security or such portion hereof until and including, but (unless the Company defaults in making the payment due upon redemption or repurchase) not after, the close of business on the Business Day immediately preceding the Redemption Date or Repurchase Date, as the case may be, to convert this Security (or any portion of the principal amount hereof which is U.S.$1,000 or an integral multiple thereof), at the principal amount hereof, or of such portion, into fully paid and nonassessable shares of Common Stock of the Company at a conversion price equal to $127.44 aggregate principal amount of Securities for each share of Common Stock, which is equal to a conversion rate of 7.8468 shares of common stock per $1,000 principal amount of the Securities (or at the current adjusted conversion price if an adjustment has been made as provided in Article 13 of the <PAGE> Indenture) by surrender of this Security, duly endorsed or assigned to the Company or in blank, to the Company at its office or agency in the Borough of Manhattan, The City of New York, accompanied by the conversion notice hereon executed by the Holder hereof evidencing such Holder's election to convert this Security, or if less than the entire principal amount hereof is to be converted, the portion hereof to be converted, and, in case such surrender shall be made during the period from the close of business on any Regular Record Date to the opening of business on the corresponding Interest Payment Date (unless this Security or the portion hereof being converted has been called for redemption on a Redemption Date within such period between and including such Regular Record Date and such Interest Payment Date), also accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted. Subject to the aforesaid requirement for payment of interest and, in the case of a conversion after the close of business on any Regular Record Date and on or before the corresponding Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an installment of interest (even if the Security has been called for redemption on a Redemption Date within such period), no payment or adjustment is to be made on conversion for interest accrued hereon or for dividends on the Common Stock issued on conversion. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest the Company shall pay a cash adjustment or round up to the next higher whole share as provided in Article 13 of the Indenture. The conversion price is subject to adjustment as provided in Article 13 of the Indenture. In addition, the Indenture provides that in case of certain reclassifications, consolidations, mergers, sales or transfers of assets or other transactions pursuant to which the Common Stock is converted into the right to receive other securities, cash or other property, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then outstanding, will be convertible thereafter, during the period this Security shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon the transaction by a holder of the number of shares of Common Stock into which this Security might have been converted immediately prior to such transaction (assuming such holder of Common Stock failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of non-electing shares). The Company will furnish to any Holder, upon request and without charge, copies of the certificate of incorporation and by-laws of the Company then in effect. Any such request may be addressed to the Company. The Securities may be redeemed at the election of the Company, as a whole or from time to time in part, at any time prior to December 21, 2002 (a "Provisional Redemption"), at a Redemption Price equal to $1,000 per $1,000 principal amount of the Securities plus accrued and unpaid interest, if any, to but excluding the date of redemption (the "Provisional Redemption Date") if the Closing Price of the Common Stock has exceeded 150% of the conversion price (as defined in Article 13 of the Indenture) then in effect for at least 20 Trading Days in any consecutive 30- <PAGE> Trading Day period ending on the Trading Day prior to the date of mailing of the provisional notice of redemption pursuant to Section 11.04 (the "Notice Date"). Upon any such Provisional Redemption, the Company shall make an additional payment in cash (the "Make-Whole Payment") to holders of the Securities called for redemption, including those Securities converted into Common Stock between the Notice Date and the Provisional Redemption Date, in an amount equal to $152.54 per $1,000 principal amount of the Securities, less the amount of any interest actually paid on the Securities before the Notice Date. The Securities (other than those Securities that have been converted in accordance with the terms of the Indenture) are subject to redemption at the option of the Company upon not less than 30 days' or more than 60 days' notice by mail (unless a shorter notice is deemed satisfactory by the Trustee), as a whole or from time to time in part, at any time on or after December 21, 2002. The Redemption Prices (expressed as percentages of the principal amount) shall be as set forth below for Securities redeemed during the following 12-month period: --------------------------------------------------------------------------- Period Redemption Price --------------------------------------------------------------------------- December 21, 2002 through December 21, 2003 102.2% --------------------------------------------------------------------------- and thereafter at a Redemption Price equal to 101.1% of the principal amount, together, in the case of any such redemption, with accrued interest to (but not including) the Redemption Date (subject to the right of holders of record on the Regular Record Date to receive interest on the related Interest Payment Date). Any redemption of Securities must be in integral multiples of $1,000. If fewer than all of the Securities are to be redeemed, the Trustee will select the Securities to be redeemed in principal amounts at maturity of $1,000 or integral multiples thereof by lot, pro rata or by another method the Trustee considers fair and appropriate. If a portion of a Holder's Securities is selected for partial redemption and that holder converts a portion of those Securities prior to the redemption, the converted portion shall be deemed, solely for purposes of determining the aggregate principal amount of the Securities to be redeemed by the Company, to be of the portion selected for redemption. In certain circumstances involving a Change in Control, each Holder shall have the right to require the Company to repurchase all or part of its Securities at a repurchase price equal to 100% of the principal amount thereof, together with accrued and unpaid interest through the Repurchase Date (subject to the right of holders of record on the Regular Record Date to receive interest on the related Interest Payment Date). At the option of the Company, the Repurchase Price may be paid in cash or, subject to the conditions provided in the Indenture, by delivery of shares of Common Stock having a fair market value equal to the Repurchase Price. For the purposes of this paragraph, the fair market value of shares of Common Stock shall be determined by the Company and shall be equal to 95% of the average of the Closing Prices of the Common <PAGE> Stock for the five consecutive Trading Days ending on and including the Third Trading Day immediately preceding the Repurchase Date. The Securities do not have the benefit of any sinking fund. In the event of redemption, conversion or repurchase of this Security in part only, a new Security or Securities for the unredeemed, unconverted or unrepurchased portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. The indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. If an Event of Default shall occur and be continuing, the principal of all the Securities may be declared due and payable in the manner and with the effect provided in Article 5 of the Indenture. Subject to certain conditions set forth in the Indenture, the Company at any time may terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. <PAGE> As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the Corporate Trust Office duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. The Securities are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, upon request of, and delivery of not less than three Business Days notice to the Company and the Trustee, a beneficial owner of interests in a permanent global security may exchange such interests for a definitive Security of like tenor and aggregate principal amount in certificated form. The depositary with respect to the Securities shall be The Depository Trust Company. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not payment of or on this Security is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. Interest on this Security shall be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Securities is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay). All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES. <PAGE> FORM OF CONVERSION NOTICE CONVERSION NOTICE To: INTERNET CAPITAL GROUP, INC.
