The aggregate principal amount of Securities outstanding at any time may not exceed $172,500,000, except as provided in Section 2.7. The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. SECTION 2.3. Registrar, Paying Agent and Conversion Agent. -------------------------------------------- The Company shall maintain one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a "Registrar"), one or more offices or agencies where

-8- Securities may be presented for payment (each, a "Paying Agent"), one or more offices or agencies where Securities may be presented for conversion (each, a "Conversion Agent") and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, the City of New York. One of the Registrars (the "Primary Registrar") shall keep a register of the Securities and of their transfer and exchange. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Section 6.1 and Article 10). The Company hereby initially designates the Trustee as Paying Agent, Registrar, Custodian and Conversion Agent. SECTION 2.4. Paying Agent to Hold Money in Trust. ----------------------------------- Prior to 12:00 noon, New York City time, on each due date of the principal of or interest, if any, on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal or interest, if any, so becoming due. A Paying Agent shall hold in trust for the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of or interest, if any, on the Securities, and shall notify the Trustee of any Default by the Company (or any other obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 12:00 noon, New York City time, on each due date of the principal of or interest on any Securities, segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to forthwith pay to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. SECTION 2.5. Security Holder Lists. --------------------- The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee on or before each semiannual interest payment date and at such other times as the Trustee may request in writing a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. SECTION 2.6. Transfer and Exchange. --------------------- (a) When a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. Furthermore, the Depositary shall, by acceptance of a Global Certificate, agree

-9- that transfers of beneficial interests in such Global Certificate may be effected only through a book-entry system maintained by the Depositary (or its agent), and that ownership of a beneficial interest in the Security shall be required to be reflected in a book-entry system. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.3, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar's request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax,assessment or other governmental charge that may be imposed in relation thereto, and provided, that this sentence shall not apply to any exchange pursuant to Section 2.7, 2.10, 2.12(a)(1), 3.6, 3.11, 4.2 (last paragraph) or 11.5. Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of (a) any Securities for a period of 15 days next preceding any mailing of a notice of Securities to be redeemed, (b) any Securities or portions thereof selected or called for redemption (except, in the case of redemption of a Security in part, the portion not to be redeemed) or (c) any Securities or portions thereof in respect of which a Change in Control Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion not to be purchased). All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. (b) Any Registrar appointed pursuant to Section 2.3 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. SECTION 2.7. Replacement Securities. ---------------------- If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such Security or indemnity as will be required by them to save each of them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be redeemed or purchased by the Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Security, pay, redeem or purchase such Security, as the case may be. Upon the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. Every new Security issued pursuant to this Section 2.7 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 benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

-10- The provisions of this Section 2.7 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 2.8. Outstanding Securities. ---------------------- Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.8 as not outstanding. If a Security is paid, redeemed, purchased or replaced pursuant to Section 2.7, it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. If a Paying Agent (other than the Company or an Affiliate of the Company) holds on a Redemption Date, a Change in Control Purchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any) and accrued interest on Securities (or portions thereof) payable on that date, then on and after that date such Securities (or portions thereof, as the case may be) cease to be outstanding and interest on them ceases to accrue. Subject to the restrictions contained in Section 2.9, a Security does not cease to be outstanding and need not be canceled if the Company or an Affiliate of the Company holds the Security. SECTION 2.9. Treasury Securities. ------------------- In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. SECTION 2.10. Temporary Securities. -------------------- Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company with the consent of the Trustee considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities. SECTION 2.11. Cancellation. ------------ The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee and no one else shall cancel, in accordance

-11- with its standard procedures, all Securities surrendered for transfer, exchange, redemption, payment, conversion or cancellation and shall deliver the canceled Securities to the Company. All Securities which are redeemed, purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date shall be delivered to the Trustee for cancellation and the Company may not hold or resell such Securities or issue any new Securities to replace any such Securities or any Securities that any Holder has converted pursuant to Article 4. SECTION 2.12. Book-Entry Provisions for Global Securities. ------------------------------------------- (a) Transfer and Exchange of Global Securities. ------------------------------------------ (1) Certificated Securities shall be issued in exchange for interests in the Global Securities only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for the Global Securities or if it at any time ceases to be a "clearing agency" registered under the Exchange Act, if so required by applicable law or regulation and a successor depositary is not appointed by the Company within 90 days, or (y) an Event of Default has occurred and is continuing. In either case, the Company shall execute, and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Securities in exchange therefor. Certificated Securities issued in exchange for beneficial interests in Global Securities shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Certificated Securities to the persons in whose names such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. (2) Notwithstanding any other provisions of this Indenture other than the provisions set forth in Section 2.12(a)(1), a Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (b) Transfer and Exchange of Certificated Securities. In the event ------------------------------------------------ that Certificated Securities are issued in exchange for beneficial interests in Global Securities in accordance with Section 2.12(a)(1) of this Indenture, on or after such event when Certificated Securities are presented by a Holder to a Registrar with a request: (x) to register the transfer of the Certificated Securities to a person who will take delivery thereof in the form of Certificated Securities only; or (y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations, such Registrar shall register the transfer or make the exchange as requested; provided, however, that the Certificated Securities presented or surrendered for register of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.6(a): (c) Transfers of Certificated Securities for Beneficial Interest in --------------------------------------------------------------- Global Securities. In the event that Certificated Securities are issued in - ----------------- exchange for beneficial interests in Global Securities and, thereaf-

-12- ter, the events or conditions specified in Section 2.12(a)(1) which required such exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Certificated Securities for interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request: (x) to register the transfer of such Certificated Securities to a person who will take delivery thereof in the form of a beneficial interest in a Global Security; or (y) to exchange such Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which beneficial interests will be owned by the Holder transferring such Certificated Securities, the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Security and causing, or directing the Securities Custodian to cause, the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security is then outstanding, the Company shall issue and the Trustee shall authenticate and deliver a new Global Security; provided, however, that the Certificated Securities presented or surrendered for - -------- ------- registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.6(a). (d) Transfers to the Company. Nothing in this Indenture or in the ------------------------ Securities shall prohibit the sale or other transfer of any Securities (including beneficial interests in Global Securities) to the Company or any of its Subsidiaries, which Securities shall thereupon be cancelled in accordance with the last sentence of Section 2.11. SECTION 2.13. CUSIP Numbers. ------------- The Company in issuing the Securities may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices of redemption or purchase as a convenience to Holders; provided that any such -------- notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption or purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption or purchase shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers. SECTION 2.14. Defaulted Interest. ------------------ Any interest on any Security which is payable, but is not punctually paid or duly provided for, on any interest payment date ("Defaulted Interest"), shall forthwith cease to be payable to the Holder on the relevant regular record date, and such Defaulted Interest may be paid by the Company as follows. The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the 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, 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 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 section provided. Thereupon the Company shall fix a special record date for the

-13- payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment, and notify the Trustee thereof. The Trustee shall, in the name and at the expense of the Company, cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be given to each Holder of Securities pursuant to Section 12.2, not less than 10 days prior to such special record date. Notice of the proposed payment of such defaulted interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities are registered at the close of business on such special record date. Alternatively, the Company may elect to 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 any 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 section, such manner of payment shall be deemed practicable by the Trustee. ARTICLE 3 REDEMPTION AND PURCHASES SECTION 3.1. Right to Redeem; Notice to Trustee. ---------------------------------- The Securities may be redeemed at the election of the Company, as a whole or from time to time in part, at any time on or after July 5, 2004, on at least 20 days and no more than 60 days notice at the Redemption Prices specified in paragraph 5 of the form of Security attached hereto as Exhibit A, together --------- with accrued interest up to but not including the Redemption Date. If the Company elects to redeem Securities pursuant to this Section 3.1 and paragraph 5 of the Securities, it shall notify the Trustee, at the earlier of the time the Company notifies the Holders of such redemption or 45 days prior to the Redemption Date as fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), of the Redemption Date and the principal amount of Securities to be redeemed. If fewer than all of the Securities are to be redeemed, the record date relating to such redemption shall be selected by the Company and given to the Trustee, which record date shall not be less than ten days after the date of notice to the Trustee. SECTION 3.2. Selection of Securities to Be Redeemed. -------------------------------------- If fewer than all of the Securities are to be redeemed, the Trustee shall, not more than 60 days prior to the Redemption Date, select the Securities to be redeemed. The Trustee shall make the selection from the Securities outstanding and not previously called for redemption, by lot, or in its discretion, on a pro rata basis. Securities in denominations of $1,000 may only -------- be redeemed in whole. The Trustee may select for redemption portions (equal to $1,000 or any multiple thereof) of the principal of Securities that have denominations larger than $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. If any Security selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed for purposes of selection only to be the portion selected for redemption. Securities which have

-14- been converted during a selection of Securities to be redeemed shall be treated by the Trustee as outstanding for the purpose of such selection. SECTION 3.3. Notice of Redemption. -------------------- At least 20 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption to each Holder of Securities to be redeemed at such Holder's address as it appears on the Primary Registrar's books. The notice shall identify the Securities (including CUSIP numbers) to be redeemed and shall state: (1) the Redemption Date; (2) the Redemption Price; (3) the then current Conversion Price; (4) the name and address of each Paying Agent and Conversion Agent; (5) that Securities called for redemption must be presented and surrendered to a Paying Agent to collect the Redemption Price; (6) that Holders who wish to convert Securities must surrender such Securities for conversion no later than the close of business on the Business Day immediately preceding the Redemption Date and must satisfy the other requirements in paragraph 8 of the Securities; (7) that, unless the Company defaults in making the redemption payment, interest on Securities called for redemption shall cease accruing on and after the Redemption Date and the only remaining right of the Holder shall be to receive payment of the Redemption Price, plus accrued interest, if any, upon presentation and surrender to a Paying Agent of the Securities; and (8) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, upon presentation and surrender of such Security, a new Security or Securities in aggregate principal amount equal to the unredeemed portion thereof will be issued. If any of the Securities to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to redemptions. At the Company's written request, which request shall (i) be irrevocable once given and (ii) set forth all relevant information required by clauses (1) through (8) of the preceding paragraph, the Trustee shall give the notice of redemption in the Company's name and at the Company's expense. SECTION 3.4. Effect of Notice of Redemption. ------------------------------ Once notice of redemption is mailed, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the notice, together with accrued interest, if any, except for Securities that are converted in accordance with the provisions of Article 4. Upon presentation and

-15- surrender to a Paying Agent, Securities called for redemption shall be paid at the Redemption Price, plus accrued interest up to but not including the Redemption Date. SECTION 3.5. Deposit of Redemption Price. --------------------------- The Company, prior to 12:00 noon New York City time, on the Redemption Date, shall deposit with a Paying Agent (or, if the Company acts as Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price of and accrued interest on all Securities 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. The Paying Agent shall return to the Company any money not required for that purpose because of the conversion of Securities pursuant to Article 4 or, if such money is then held by the Company in trust and is not required for such purpose, it shall be discharged from the trust. SECTION 3.6. Securities Redeemed in Part. --------------------------- Upon presentation and surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security equal in principal amount to the unredeemed portion of the Security surrendered. SECTION 3.7. Conversion Arrangement on Call for Redemption. --------------------------------------------- In connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities called for redemption by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to a Paying Agent (other than the Company or any of its Affiliates) in trust for the Holders, on or before noon, New York City time on the Redemption Date, an amount that, together with any amounts deposited with such Paying Agent by the Company for the redemption of such Securities, is not less than the Redemption Price, together with interest accrued to, but not including, the Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the Redemption Price of such Securities, including all accrued interest, if any, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers; provided, however, that nothing in this Section 3.7 shall relieve the Company of its obligation to pay the Redemption Price, plus accrued interest to but excluding the relevant Redemption Date, on Securities called for redemption. If such an agreement with one or more investment banks or other purchasers is entered into, any Securities called for redemption and not surrendered for conversion by the Holders thereof prior to the relevant Redemption Date may, at the option of the Company upon written notice to the Trustee, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 4) surrendered by such purchasers for conversion, all as of noon, New York City time on the Redemption Date, subject to payment of the above amount as aforesaid. The Paying Agent shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it for purchase in the same manner as it would money deposited with it by the Company for the redemption of Securities. Without the Paying Agent's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Paying Agent as set forth in this Indenture, and the Company agrees to indemnify the Paying Agent from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses incurred by the Paying Agent in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture.

-16- SECTION 3.8. Purchase of Securities at Option of the Holder upon Change in ------------------------------------------------------------- Control. ------- (a) If at any time that Securities remain outstanding there shall occur a Change in Control, Securities shall be purchased by the Company at the option of the Holders thereof as of the date that is 30 Business Days after the occurrence of the Change in Control (the "Change in Control Purchase Date") at a purchase price equal to the principal amount of the Securities, plus accrued and unpaid interest to, but excluding, the Change in Control Purchase Date (the "Change in Control Purchase Price"), subject to satisfaction by or on behalf of any Holder of the requirements set forth in subsection (c) of this Section 3.8. A "Change in Control" shall be deemed to have occurred if any of the following occurs after the date hereof: (1) any Person or "group" (as such term is defined below), other than one or more Permitted Holders, is or becomes the "beneficial owner," directly or indirectly, of shares of Voting Stock of the Company representing 50% or more of the total voting power of all outstanding classes of Voting Stock of the Company or such Person or "group," other than one or more Permitted Holders, has the power, directly or indirectly, to elect a majority of the members of the Board of Directors of the Company; or (2) any Permitted Holder purchases shares of Common Stock and solely as a result of such purchase and after giving effect thereto, the aggregate number of shares of Common Stock "beneficially owned" by all Permitted Holders exceeds 25% of the total number of shares of Common Stock then issued and outstanding; or (3) the Company consolidates with, or merges with or into, another Person or the Company sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of the assets of the Company, or any Person consolidates with, or merges with or into, the Company, in any such event other than pursuant to a transaction in which the Person or Persons that "beneficially owned," directly or indirectly, shares of Voting Stock of the Company immediately prior to such transaction "beneficially own," directly or indirectly, shares of Voting Stock of the Company representing at least a majority of the total voting power of all outstanding classes of Voting Stock of the surviving or transferee Person; or (4) there shall occur the liquidation or dissolution of the Company. For the purpose of the definition of "Change in Control", (i) "group" has the meanings given such terms under Section 13(d) and 14(d) of the Exchange Act or any successor provision to either of the foregoing, including any group acting for the purpose of acquiring, holding or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor provision thereto), (ii) a "beneficial owner" shall be determined in accordance with Rule 13d-3 under the Exchange Act, as in effect on the date of this Indenture, except that the number of shares of Voting Stock of the Company shall be deemed to include, in addition to all outstanding shares of Voting Stock of the Company and Unissued Shares deemed to be held by the "group" (as such terms are defined above) or other Person with respect to which the Change in Control determination is being made, all Unissued Shares deemed to be held by all other Persons and (iii) the terms "beneficially owned" and "beneficially own" shall have meanings correlative to that of "beneficial owner." The term "Unissued Shares" means shares of Voting Stock not outstanding that are subject to options, warrants, rights to purchase or conversion privileges exercisable within 60 days after the date of determination of a Change in Control.

-17- Notwithstanding anything to the contrary set forth in this Section 3.8, a Change in Control will not be deemed to have occurred if either: (1) the Closing Price of the Common Stock for any five Trading Days during the ten Trading Days immediately preceding the Change in Control is at least equal to 105% of the Conversion Price in effect on such Trading Day; or (2) in the case of a merger or consolidation, all of the consideration (excluding cash payments for fractional shares in the merger or consolidation constituting the Change in Control) consists of common stock traded on a United States national securities exchange or quoted on the Nasdaq National Market (or which will be so traded or quoted when issued or exchanged in connection with such Change In Control) and as a result of such transaction or transactions the Securities become convertible solely into such common stock. (b) Within 10 Business Days after the occurrence of a Change in Control, the Company shall mail a written notice of the Change in Control to the Trustee (and the Paying Agent if the Trustee is not then acting as Paying Agent) and to each Holder (and to beneficial owners as required by applicable law). The notice shall include the form of a Change in Control Purchase Notice to be completed by the Holder, the applicable CUSIP number and shall state: (1) the date of such Change in Control and, briefly, the events causing such Change in Control; (2) the date by which the Change in Control Purchase Notice pursuant to this Section 3.8 must be given; (3) the Change in Control Purchase Date; (4) the Change in Control Purchase Price; (5) briefly, the conversion rights of the Securities; (6) the name and address of each Paying Agent and Conversion Agent; (7) the Conversion Price and any adjustments thereto; (8) that Securities as to which a Change in Control Purchase Notice has been given may be converted into Common Stock pursuant to Article 4 of this Indenture only to the extent that the Change in Control Purchase Notice has been withdrawn in accordance with the terms of this Indenture; (9) the procedures that the Holder must follow to exercise rights under this Section 3.8; (10) the procedures for withdrawing a Change in Control Purchase Notice, including a form of notice of withdrawal; and (11) that the Holder must satisfy the requirements set forth in the Securities in order to convert the Securities.

-18- If any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to the repurchase of Global Securities. (c) A Holder may exercise its rights specified in subsection (a) of this Section 3.8 upon delivery of a written notice (which shall be in substantially the form included in Exhibit A hereto and which may be delivered --------- by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary's customary procedures) of the exercise of such rights (a "Change in Control Purchase Notice") to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date. The delivery of such Security to any Paying Agent (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Change in Control Purchase Price therefor. The Company shall purchase from the Holder thereof, pursuant to this Section 3.8, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of the Indenture that apply to the purchase of all of a Security pursuant to Sections 3.8 through 3.13 also apply to the purchase of such portion of such Security. Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Change in Control Purchase Notice contemplated by this subsection (c) shall have the right to withdraw such Change in Control Purchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.9. A Paying Agent shall promptly notify the Company of the receipt by it of any Change in Control Purchase Notice or written withdrawal thereof. Anything herein to the contrary notwithstanding, in the case of Global Securities, any Change in Control Purchase Notice may be delivered or withdrawn and such Securities may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in effect from time to time. SECTION 3.9. Effect of Change in Control Purchase Notice. ------------------------------------------- Upon receipt by any Paying Agent of the Change in Control Purchase Notice specified in Section 3.8(c), the Holder of the Security in respect of which such Change in Control Purchase Notice was given shall (unless such Change in Control Purchase Notice is withdrawn as specified below) thereafter be entitled to receive solely the Change in Control Purchase Price with respect to such Security. Such Change in Control Purchase Price shall be paid to such Holder promptly following the later of (a) the Change in Control Purchase Date with respect to such Security (provided the conditions in Section 3.8(c) have been satisfied) and (b) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.8(c). Securities in respect of which a Change in Control Purchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock on or after the date of the delivery of such Change in Control Purchase Notice unless such Change in Control Purchase Notice has first been validly withdrawn.

-19- A Change in Control Purchase Notice may be withdrawn by means of a written notice (which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary's customary procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Change in Control Purchase Date, specifying: (1) the name of the Holder; (2) the certificate number of each Security or portion thereof with respect to which such notice of withdrawal is being submitted; (3) the principal amount of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice is being submitted; and (4) the principal amount, if any, of such Security that remains subject to the original Change in Control Purchase Notice and that has been or will be delivered for purchase by the Company. SECTION 3.10. Deposit of Change in Control Purchase Price. ------------------------------------------- On or before 12:00 noon., New York City time, on the Change in Control Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent (other than the Company or an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Change in Control Purchase Price of all the Securities or portions thereof that are to be purchased as of such Change in Control Purchase Date. The manner in which the deposit required by this Section 3.10 is made by the Company shall be at the option of the Company, provided that such deposit shall be made in a manner such that the Trustee or a Paying Agent shall have immediately available funds on the Change in Control Purchase Date. If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Change in Control Purchase Price of any Security for which a Change in Control Purchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Change in Control Purchase Date, such Security will cease to be outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Change in Control Purchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities purchased as a result of such Change in Control on or as soon as practicable after the Change in Control Purchase Date. SECTION 3.11. Securities Purchased in Part. ---------------------------- Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent and promptly after the Change in Control Purchase Date 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 such authorized denomination or denominations as may be requested by such Holder, in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased.

-20- SECTION 3.12. Compliance with Securities Laws upon Purchase of Securities. ----------------------------------------------------------- In connection with any offer to purchase or purchase of Securities under Section 3.8, the Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor to either such Rule), if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and obligations of the Company under Sections 3.8 through 3.11 to be exercised in the time and in the manner specified therein. SECTION 3.13. Repayment to the Company. ------------------------ To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.10 exceeds the aggregate Change in Control Purchase Price together with interest, if any, thereon of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Change in Control Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash (including any interest thereon) to the Company. ARTICLE 4 CONVERSION SECTION 4.1. Conversion Privilege. -------------------- Subject to the further provisions of this Section 4.1, a Holder of a Security may convert the principal amount of such Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into Common Stock at any time prior to the close of business on the Final Maturity Date, at the Conversion Price then in effect; provided, however, that, if such Security is called for redemption or submitted or presented for purchase pursuant to Article 3, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Redemption Date or Change in Control Purchase Date, as the case may be, for such Security or such earlier date as the Holder presents such Security for redemption or for purchase (unless the Company shall Default in making the redemption payment or Change in Control Purchase Price payment when due, in which case the conversion right shall terminate at the close of business on the date such Default is cured and such Security is redeemed or purchased, as the case may be). The number of shares of Common Stock issuable upon conversion of a Security shall be determined by dividing the principal amount of the Security or portion thereof surrendered for conversion by the Conversion Price in effect on the Conversion Date. The initial Conversion Price is set forth in paragraph 8 of the Securities and is subject to adjustment as provided in this Article 4. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security. A Security in respect of which a Holder has delivered a Change in Control Purchase Notice pursuant to Section 3.8(c) exercising the option of such Holder to require the Company to purchase such Security may be converted only if such Change in Control Purchase Notice is withdrawn by a written notice of withdrawal delivered to a Paying Agent prior to the close of business on the Business Day immediately preceding the Change in Control Purchase Date in accordance with Section 3.9.

-21- A Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities to Common Stock, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 4. SECTION 4.2. Conversion Procedure. -------------------- To convert a Security, a Holder must (a) complete and manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax, if required. The date on which the Holder satisfies all of those requirements is the "Conversion Date." As soon as practicable after the Conversion Date, the Company shall deliver to the Holder through a Conversion Agent a certificate for the number of whole shares of Common Stock issuable upon the conversion, payment for accrued interest on such Security to the extent required by this Section 4.2 and ,if applicable, cash in lieu of any fractional shares pursuant to Section 4.3. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may be surrendered for conversion in accordance with the Applicable Procedures as in effect from time to time. The person in whose name the Common Stock certificate is registered shall be deemed to be a stockholder of record on the Conversion Date; provided, however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided, further, that such conversion shall be at the Conversion Price in effect on the Conversion Date as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security. No payment or adjustment will be made for dividends or distributions on shares of Common Stock issued upon conversion of a Security. Securities so surrendered for conversion (in whole or in part) during the period from the close of business on any regular record date to the opening of business on the next succeeding interest payment date (excluding Securities or portions thereof called for redemption or presented for purchase upon a Change in Control on a Redemption Date or Change in Control Purchase Date, as the case may be, during the period beginning at the close of business on a regular record date and ending at the opening of business on the first Business Day after the next succeeding interest payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be 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 such Security then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such Security, subject to the provisions of this Indenture relating to the payment of defaulted interest by the Company. Except as otherwise provided in this Section 4.2, no payment or adjustment will be made for accrued interest on a converted Security. If the Company defaults in the payment of interest payable on such interest payment date, the Company shall promptly repay such funds to such Holder. Nothing in this Section shall affect the right of a Holder in whose name any Security is registered at the close of business on a record date to receive the interest payable on such Security on the related interest payment date in accordance with the terms of this Indenture and the Securities. If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the aggregate principal amount of Securities converted.

-22- Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security equal in principal amount to the unconverted portion of the Security surrendered. SECTION 4.3. Fractional Shares. ----------------- The Company will not issue fractional shares of Common Stock upon conversion of Securities. In lieu thereof, the Company will, at its option, either (a) round the number of shares of Common Stock issuable upon conversion of a Security up to the nearest whole share, or (b) pay an amount in cash based upon the Closing Price of the Common Stock on the Trading Day immediately prior to the Conversion Date. SECTION 4.4. Taxes on Conversion. ------------------- If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. The Conversion Agent may refuse to deliver the certificate representing the Common Stock being issued in a name other than the Holder's name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude any tax withholding required by law or regulation. SECTION 4.5. Company to Provide Stock. ------------------------ The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock. All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or on the Nasdaq National Market or other over-the-counter market or such other market on which the Common Stock is then listed or quoted; provided, however, that if rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Notes into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such automated quotation system or exchange at such time. SECTION 4.6. Adjustment of Conversion Price. ------------------------------ The conversion price as stated in paragraph 8 of the Securities (the "Conversion Price") shall be adjusted from time to time by the Company as follows: (a) In case the Company shall (i) pay a dividend on its Common Stock in shares of Common Stock, (ii) make a distribution on its Common Stock in shares of Common Stock, (iii) subdivide its outstanding Common Stock into a greater number of shares, or (iv) combine its outstanding Common

-23- Stock into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have owned had such Security been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision or combination. (b) In case the Company shall issue rights or warrants to all or substantially all holders of its Common Stock entitling them (for a period commencing no earlier than the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price Per Share of Common Stock on the record date for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price in effect immediately prior thereto shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such record date by a fraction of which (x) the numerator shall be the number of shares of Common Stock outstanding on such record date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered (or the aggregate conversion price of the convertible securities so offered, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at the Current Market Price Per Share of Common Stock on such record date, and of which (y) the denominator shall be the number of shares of Common Stock outstanding on such record date plus the number of additional shares of Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after such record date. If at the end of the period during which such rights or warrants are exercisable not all rights or warrants shall have been exercised, the adjusted Conversion Price shall be immediately readjusted to what it would have been based upon the number of additional shares of Common Stock actually issued (or the number of shares of Common Stock issuable upon conversion of convertible securities actually issued). (c) In case the Company shall distribute to all or substantially all holders of its Common Stock any shares of capital stock of the Company (other than Common Stock), evidences of indebtedness or other non-cash assets (including securities of any Person other than the Company but excluding (1) dividends or distributions paid exclusively in cash or (2) dividends or distributions referred to in subsection (a) of this Section 4.6), or shall distribute to all or substantially all holders of its Common Stock rights or warrants to subscribe for or purchase any of its securities (excluding those rights and warrants referred to in subsection (b) of this Section 4.6 and also excluding the distribution of rights to all holders of Common Stock pursuant to the adoption of a stockholders rights plan or the detachment of such rights under the terms of such stockholder rights plan), then in each such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such distribution by a fraction of which the numerator shall be the Current Market Price Per Share of the Common Stock on the record date mentioned below less the fair market value on such record date (as reasonably determined in good faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of the portion of the capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the

-24- record date), and of which the denominator shall be the Current Market Price Per Share of the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (d) In case the Company shall, by dividend or otherwise, at any time distribute (a "Triggering Distribution") to all or substantially all holders of its Common Stock cash in an aggregate amount that, together with the aggregate amount of (A) any cash and the fair market value (as reasonably determined in good faith by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of any other consideration payable in respect of any tender offer by the Company or a Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 4.6 has been made and (B) all other cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Price adjustment pursuant to this Section 4.6 has been made, exceeds an amount equal to 12.5% of the product of the Current Market Price Per Share of Common Stock on the Business Day (the "Determination Date") immediately preceding the day on which such Triggering Distribution is declared by the Company multiplied by the number of shares of Common Stock outstanding on the Determination Date (excluding shares held in the treasury of the Company), the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying such Conversion Price in effect immediately prior to the Determination Date by a fraction of which the numerator shall be the Current Market Price Per Share of the Common Stock on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (as reasonably determined in good faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of any such other consideration so distributed, paid or payable within such 12 months (including, without limitation, the Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Determination Date) and the denominator shall be such Current Market Price Per Share of the Common Stock on the Determination Date, such reduction to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. (e) (1) In case any tender offer made by the Company or any of its Subsidiaries for Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall involve the payment of aggregate consideration in an amount (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as reasonably determined in good faith by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee thereof) of any other consideration) that, together with the aggregate amount of (A) any cash and the fair market value (as reasonably determined in good faith by the Board of Directors, whose determination shall be conclusive evidence thereof and which shall be evidenced by an Officers' Certificate delivered to the Trustee) of any other consideration payable in respect of any other tender offers by the Company or any Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of the Expiration Date (as defined below) and in respect of which no Conversion Price adjustment pursuant to this Section 4.6 has been made and (B) all cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the Expiration Date and in respect of which no Conversion Price adjustment pursuant to this Section 4.6 has been made, exceeds an amount equal to 12.5% of the product of the Current Market Price Per Share of Common Stock as of the last date (the "Expiration Date")

-25- tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the "Expiration Time") multiplied by the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time, then, immediately prior to the opening of business on the day after the Expiration 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 close of business on the Expiration Date by a fraction of which the numerator shall be the product of the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the Current Market Price Per Share of the Common Stock on the Trading Day next succeeding the Expiration Date and the denominator shall be the sum of (x) the aggregate consideration (determined as aforesaid) payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered 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 (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the Current Market Price Per Share of Common Stock on the Trading Day next succeeding the Expiration Date, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted to be the Conversion Price which would have been in effect based upon the number of shares actually purchased. If the application of this Section 4.6(e) to any tender offer would result in an increase in the Conversion Price, no adjustment shall be made for such tender offer under this Section 4.6(e). (2) For purposes of Section 4.6(d) and 4.6(e), the term "tender offer" shall mean and include both tender offers and exchange offers (within the meaning of U.S. Federal securities laws), all references to "purchases" of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all references to "tendered shares" (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. (f) For the purpose of any computation under subsections (b), (c), (d) and (e) of this Section 4.6, the current market price per share of Common Stock (the "Current Market Price Per Share") on any date shall be deemed to be the average of the daily Closing Prices for the 30 consecutive Trading Days commencing 45 Trading Days before (i) the Determination Date or the Expiration Date, as the case may be, with respect to distributions or tender offers under subsection (e) of this Section 4.6 or (ii) the record date with respect to distributions, issuances or other events requiring such computation under subsection (b), (c) or (d) of this Section 4.6. The Closing Price for each day (the "Closing Price") shall be the last reported sales price or, in case no such reported sale takes place on such date, the average of the reported closing bid and asked prices in either case on the New York Stock Exchange (the "NYSE") or the Nasdaq National Market (the "NNM"), as applicable, or, if the Common Stock is not listed or admitted to trading on the NYSE or the NNM, the principal national securities exchange or quotation system on which the Common Stock is quoted or listed or admitted to trading or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the closing sales price or, in case no reported sale takes place, the average of the closing bid and asked prices, as furnished by any two members of the National Association of Securities Dealers, Inc. selected from time to time by the Company for that purpose. If no such prices are available, the Current Market Price Per Share shall be

-26- the fair value of a share of Common Stock as reasonably determined in good faith by the Board of Directors (which shall be evidenced by an Officers' Certificate delivered to the Trustee). (g) In any case in which this Section 4.6 shall require that an adjustment be made following a record date or a Determination Date or Expiration Date, as the case may be, established for purposes of this Section 4.6, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 4.9) issuing to the Holder of any Security converted after such record date or Determination Date or Expiration Date the shares of Common Stock and other capital stock of the Company issuable upon such conversion over and above the shares of Common Stock and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the record date or Determination Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or such effective date or Determination Date or Expiration Date had not occurred. SECTION 4.7. No Adjustment. ------------- No adjustment in the Conversion Price shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price as last adjusted; provided, however, that any adjustments which by reason of this Section 4.7 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one- hundredth of a share, as the case may be. No adjustment need be made for issuances of Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for a change in the par value or a change to no par value of the Common Stock. To the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. SECTION 4.8. Adjustment for Tax Purposes. --------------------------- The Company shall be entitled to make such reductions in the Conversion Price, in addition to those required by Section 4.6, as it in its discretion shall determine to be advisable in order that any stock dividends, subdivisions of shares, distributions of rights to purchase stock or securities or distributions of securities convertible into or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. SECTION 4.9. Notice of Adjustment. -------------------- Whenever the Conversion Price or conversion privilege is adjusted, the Company shall promptly mail to Securityholders a notice of the adjustment and file with the Trustee an Officers' Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Unless and until the Trustee shall receive an Officers' Certificate setting forth an adjustment of the Conversion Price, the Trustee may assume

-27- without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has knowledge remains in effect. SECTION 4.10. Notice of Certain Transactions. ------------------------------ In the event that: (1) the Company takes any action which would require an adjustment in the Conversion Price; (2) the Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and shareholders of the Company must approve the transaction; or (3) there is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice at least ten days before such date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 4.10. SECTION 4.11. Effect of Reclassification, Consolidation, Merger or Sale on ------------------------------------------------------------ Conversion Privilege. -------------------- If any of the following shall occur, namely: (a) any reclassification or change of shares of Common Stock issuable upon conversion of the Securities (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, or any other change for which an adjustment is provided in Section 4.6); (b) any consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than 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) in, outstanding shares of Common Stock; or (c) any sale or conveyance as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to any person, then the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, change, combination, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to convert such Security into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification, change, combination, consolidation, merger, sale or conveyance. Such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 4. If, in the case of any such consolidation, merger, combination, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a person other than the successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 4.11 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, sales or conveyances.

-28- In the event the Company shall execute a supplemental indenture pursuant to this Section 4.11, the Company shall promptly file with the Trustee (x) an Officers' Certificate briefly stating the reasons therefor, the kind or amount of shares of stock or other securities or property (including cash) receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change, combination, consolidation, merger, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and (y) an Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. SECTION 4.12. Trustee's Disclaimer. -------------------- The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers' Certificate including the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.9. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article 4. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.11. SECTION 4.13. Voluntary Reduction. ------------------- The Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 days and if the reduction is irrevocable during the period if the Board of Directors determines that such reduction would be in the best interest of the Company and the Company provides 15 days prior notice of any reduction in the Conversion Price; provided, however, that in no event may the Company reduce the Conversion Price to be less than the par value of a share of Common Stock. ARTICLE 5 [RESERVED] ARTICLE 6 COVENANTS SECTION 6.1. Payment of Securities. --------------------- The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities and this Indenture. An installment of principal or interest, shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 12:00 noon, New York City time, on that date money, deposited by the Company or an Affiliate thereof, sufficient to pay the installment. The

ARTICLE 8 DEFAULT AND REMEDIES SECTION 8.1. Events of Default. ----------------- An "Event of Default" shall occur if: (1) the Company defaults in the payment of any interest, on any Security when the same becomes due and payable and the default continues for a period of 30 days; (2) the Company defaults in the payment of any principal of (including, without limitation, any premium, if any, on) any Security when the same becomes due and payable (whether at maturity, upon redemption, on a Change in Control Purchase Date or otherwise); (3) the Company fails to comply with any of its other agreements contained in the Securities or this Indenture and the default continues for the period and after the notice specified below;

-32- (4) the Company fails to give notice to the Trustee and each Holder of a Change in Control in accordance with Section 3.8(b); (5) the Company pursuant to or within the meaning of any Bankruptcy Law: (i) commences a voluntary case or proceeding; (ii) consents to the entry of an order for relief against it in an involuntary case or proceeding; (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 (6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Company in an involuntary case or proceeding; (ii) appoints a Custodian of the Company or for all or substantially all of the property of the Company; or (iii) orders the liquidation of the Company; and in each case the order or decree remains unstayed and in effect for 60 days. The term "Bankruptcy Law" means Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. A Default under clause (3) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, of the Default, and the Company does not cure the Default within 60 days after receipt of such notice. The notice given pursuant to this Section 8.1 must specify the Default, demand that it be remedied and state that the notice is a "Notice of Default." When any Default under this Section 8.1 is cured, it ceases. SECTION 8.2. Acceleration. ------------ If an Event of Default (other than an Event of Default specified in clause (5) or (6) of Section 8.1) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal on the Securities then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in clause (5) or (6) of Section 8.1 occurs, all unpaid principal of the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of

-33- Default, other than the nonpayment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) to the extent the payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities) on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 9.7 have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. SECTION 8.3. Other Remedies. -------------- If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. SECTION 8.4. Waiver of Defaults and Events of Default. ---------------------------------------- Subject to Sections 8.7 and 11.2, the Holders of a majority in principal amount of the Securities then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequence, except a Default or Event of Default in the payment of the principal of or interest on any Security, a failure by the Company to convert any Securities into Common Stock or any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 11.2, cannot be modified or amended without the consent of the Holder of each Security affected. When a Default or Event of Default is waived, it is cured and ceases. SECTION 8.5. Control by Majority. ------------------- The Holders of a majority in principal amount of the Securities then outstanding may 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 it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. SECTION 8.6. Limitations on Suits. -------------------- A Holder may not pursue any remedy with respect to this Indenture or the Securities (except actions for payment of overdue principal or interest or for the conversion of the Securities pursuant to Article 4) unless: (1) the Holder gives to the Trustee written notice of a continuing Event of Default;

-34- (2) the Holders of at least 25% in principal amount of the then outstanding Securities make a written request to the Trustee to pursue the remedy; (3) such Holder or Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and (5) 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 Securities then outstanding. A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over such other Securityholder. SECTION 8.7. Rights of Holders to Receive Payment and to Convert. --------------------------------------------------- Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of the principal of and interest on the Security, on or after the respective due dates therefor, to convert such Security in accordance with Article 4 and to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. SECTION 8.8. Collection Suit by Trustee. -------------------------- If an Event of Default in the payment of principal or interest specified in clause (1) or (2) of Section 8.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount of principal and accrued interest remaining unpaid, together with, to the extent that payment of such interest is lawful, interest on overdue principal and on overdue installments of interest, in each case at the rate per annum borne by the Securities and 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. SECTION 8.9. Trustee May File Proofs of Claim. -------------------------------- The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.7, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or

-35- under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt 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 in any such proceeding. SECTION 8.10. Priorities. ---------- If the Trustee collects any money pursuant to this Article 8, it shall pay out the money in the following order: First, to the Trustee for amounts due under Section 9.7; Second, to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and Third, to the Company. The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 8.10. SECTION 8.11. Undertaking for Costs. --------------------- In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 8.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 8.7, or a suit by Holders of more than 10% in principal amount of the Securities then outstanding. ARTICLE 9 TRUSTEE SECTION 9.1. Duties of Trustee. ----------------- (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. (b) Except during the continuance of an Event of Default: (1) the Trustee need perform only those duties as are specifically set forth in this Indenture and no others; and

-36- (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee, however, shall examine any certificates and opinions which by any provision hereof are specifically required to be delivered to the Trustee to determine whether or not they conform to the requirements of this Indenture.

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

Individual Rights of Trustee. ---------------------------- The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee.

The resignation or removal of a Trustee shall not be effective until a successor Trustee shall have delivered the written acceptance of its appointment as described below. If a successor Trustee does not take office within 45 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of 10% in principal amount of the Securities then outstanding may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Company. If the Trustee fails to comply with Section 9.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

-42- ARTICLE 11 AMENDMENTS, SUPPLEMENTS AND WAIVERS SECTION 11.1. Without Consent of Holders. -------------------------- The Company and the Trustee may amend or supplement this Indenture or the Securities without notice to or consent of any Securityholder: (a) to comply with Sections 4.11 and 7.1; (b) to provide for uncertificated Securities in addition to or in place of certificated Securities (provided that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code); (c) to comply with the provisions of the TIA; (d) to appoint a successor Trustee; (e) to cure any ambiguity, defect or inconsistency; or (f) to make any other change that does not adversely affect the rights of any Securityholder. SECTION 11.2. With Consent of Holders. ----------------------- The Company and the Trustee may amend or supplement this Indenture or the Securities with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. The Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Securities without notice to any Securityholder. However, notwithstanding the foregoing but subject to Section 11.4, without the written consent of each Securityholder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 8.4, may not: (a) change the stated maturity of the principal of, or interest on, any Security; (b) reduce the principal amount of, or any premium or interest on, any Security; (c) reduce the amount of principal payable upon acceleration of the maturity of any Security; (d) change the place or currency of payment of principal of, or any premium or interest on, any Security; (e) impair the right to institute suit for the enforcement of any payment on, or with respect to, any Security;

-43- (f) adversely affect the right of Holders to convert Securities other than as provided in or under Article 4 of this Indenture; (g) reduce the percentage of the aggregate principal amount of the outstanding Securities whose Holders must consent to a modification or amendment of this Indenture; and (h) modify any of the provisions of this Section or Section 8.4, except to increase any such percentage or to provide that specified additional provisions of this Indenture cannot be modified or waived without the consent of the Holder of each outstanding Security affected thereby. It shall not be necessary for the consent of the Holders under this Section 11.2 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 11.2 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver. SECTION 11.3. Compliance with Trust Indenture Act. ----------------------------------- Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as in effect at the date of such amendment or supplement. SECTION 11.4. Revocation and Effect of Consents. --------------------------------- Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. After an amendment, supplement or waiver becomes effective, it shall bind every Securityholder, unless it makes a change described in any of clauses (a) through (i) of Section 11.2. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security. SECTION 11.5. Notation on or Exchange of Securities. ------------------------------------- If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

-44- SECTION 11.6. Trustee to Sign Amendments, Etc. ------------------------------- The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 11 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be entitled to receive and, subject to Section 9.1, shall be fully protected in relying upon, an Opinion of Counsel stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it, which approval shall be confirmed by an Officers' Certificate of the Company to such effect. ARTICLE 12 MISCELLANEOUS SECTION 12.1. Trust Indenture Act Controls. ---------------------------- If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by any of Sections 310 to 317, inclusive, of the TIA through operation of Section 318(c) thereof, such imposed duties shall control.

-46- by vote or consent authorized or permitted under this Indenture, which record date shall not be more than thirty (30) days prior to the date of the commencement of solicitation of such action. Notwithstanding the provisions of Section 11.4, if a record date is fixed, those persons who were Holders of Securities at the close of business on such record date (or their duly designated proxies), and only those persons, shall be entitled to take such action by vote or consent or to revoke any vote or consent previously given, whether or not such persons continue to be Holders after such record date. SECTION 12.6. Rules by Trustee, Paying Agent, Registrar and Conversion Agent. -------------------------------------------------------------- The Trustee may make reasonable rules (not inconsistent with the terms of this Indenture) for action by or at a meeting of Holders.

[FORM OF REVERSE SIDE OF SECURITY] MEDIACOM COMMUNICATIONS CORPORATION 5.25% CONVERTIBLE SENIOR NOTES DUE JULY 1, 2006 1. Interest -------- Mediacom Communications Corporation, a Delaware corporation (the "Company", which term shall include any successor corporation under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 5.25% per annum. The Company shall pay interest semiannually on January 1 and July 1 of each year, commencing January 1, 2002. Interest on the Securities shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 27, 2001; provided, however, that if there is not an existing Default in the payment of interest and if this Security is authenticated between a record date referred to on the face hereof and the next succeeding interest payment date, interest shall accrue from such interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 2. Method of Payment ----------------- The Company shall pay interest on this Security (except defaulted interest) to the person who is the Holder of this Security at the close of business on December 15 or June 15, as the case may be, next preceding the related interest payment date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may, however, pay principal and interest in respect of any Certificated Security by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder. The Company may mail an interest check to the Holder's registered address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. 3. Paying Agent, Registrar and Conversion Agent -------------------------------------------- Initially, The Bank of New York (the "Trustee", which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holder. The Company or any of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent. 4. Indenture, Limitations ---------------------- This Security is one of a duly authorized issue of Securities of the Company designated as its 5.25% Convertible Senior Notes Due July 1, 2006 (the "Securities"), issued under an Indenture dated as of June 27, 2001 (together with any supplemental indentures thereto, the "Indenture"), between the Company and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of this Security include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this Security is referred to the Indenture and said Act for a statement of them. The Securities are unsecured and unsubordinated obligations of the Company limited to A-4

$172,500,000 aggregate principal amount, subject to Section 2.7 of the Indenture. The Indenture does not limit other debt of the Company, secured or unsecured. 5. Optional Redemption ------------------- The Securities are subject to redemption, at any time on or after July 5, 2004, on at least 20 days and no more than 60 days notice, in whole or in part, at the election of the Company. The Redemption Prices (expressed as percentages of the principal amount) are as follows for Securities redeemed during the periods set forth below: Period Redemption Price - ------ ---------------- Beginning on July 5, 2004 and ending on June 30, 2005..... 101.313% Beginning on July 1, 2005 and thereafter.................. 100.00% in each case together with accrued interest up to but not including the Redemption Date. 6. Notice of Redemption -------------------- Notice of redemption will be mailed by first-class mail at least 20 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at its registered address. Securities in denominations larger than $1,000 may be redeemed in part, but only in whole multiples of $1,000. On and after the Redemption Date, subject to the deposit with the Paying Agent of funds sufficient to pay the Redemption Price plus accrued interest, if any, accrued to, but excluding, the Redemption Date, interest shall cease to accrue on Securities or portions of them called for redemption. 7. Purchase of Securities at Option of Holder Upon a Change in Control ------------------------------------------------------------------- At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities held by such Holder on the date that is 30 Business Days after the occurrence of a Change in Control, at a purchase price equal to 100% of the principal amount thereof together with accrued interest up to, but excluding, the Change in Control Purchase Date. The Holder shall have the right to withdraw any Change in Control Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 8. Conversion ---------- A Holder of a Security may convert the principal amount of such Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into shares of Common Stock at any time prior to the close of business on July 1, 2006; provided, however, that if the Security is called for redemption or subject to purchase upon a Change in Control, the conversion right will terminate at the close of business on the Business Day immediately preceding the Redemption Date or the Change in Control Purchase Date, as the case may be, for such Security or such earlier date as the Holder presents such Security for redemption or purchase (unless the Company shall default in making the redemption payment or Change in Control Purchase Price, as the case may be, when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Security is redeemed or purchased). The initial Conversion Price is $18.7206 per share, subject to adjustment under certain circumstances. The number of shares of Common Stock issuable upon conversion of a Security is determined by dividing the principal amount of the Security or portion thereof converted by the Conversion Price in effect on the Conversion Date. No fractional shares will be issued upon A-5

conversion; in lieu thereof, an amount will be paid in cash based upon the Closing Price (as defined in the Indenture) of the Common Stock on the Trading Day immediately prior to the Conversion Date. To convert a Security, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax, if required. Securities so surrendered for conversion (in whole or in part) during the period from the close of business on any regular record date to the opening of business on the next succeeding interest payment date (excluding Securities or portions thereof called for redemption or subject to purchase upon a Change in Control on a Redemption Date or Change in Control Purchase Date, as the case may be, during the period beginning at the close of business on a regular record date and ending at the opening of business on the first Business Day after the next succeeding interest payment date, or if such interest payment date is not a Business Day, the second such Business Day) shall also be 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 such Security then being converted, and such interest shall be payable to such registered Holder notwithstanding the conversion of such Security, subject to the provisions of this Indenture relating to the payment of defaulted interest by the Company. If the Company defaults in the payment of interest payable on such interest payment date, the Company shall promptly repay such funds to such Holder. A Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. A Security in respect of which a Holder had delivered a Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if the Change in Control Purchase Notice is withdrawn in accordance with the terms of the Indenture. 9. Conversion Arrangement on Call for Redemption --------------------------------------------- Any Securities called for redemption, unless surrendered for conversion before the close of business on the Business Day immediately preceding the Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, together with accrued interest, if any, to, but not including, the Redemption Date, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Paying Agent in trust for such Holders. 10. Denominations, Transfer, Exchange --------------------------------- The Securities are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. A Holder may register the transfer of or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture. 11. Persons Deemed Owners --------------------- The Holder of a Security may be treated as the owner of it for all purposes. 12. Unclaimed Money --------------- If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request. After that, Holders entitled to money must look to the Company for payment. A-6

13. Amendment, Supplement and Waiver -------------------------------- Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding, and an existing Default or Event of Default and its consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance with the consent of the Holders of a majority in principal amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or make any other change that does not adversely affect the rights of any Holder. 14. Successor Corporation --------------------- When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor corporation will (except in certain circumstances specified in the Indenture) be released from those obligations. 15. Defaults and Remedies --------------------- Under the Indenture, an Event of Default includes: (i) default for 30 days in payment of any interest on any Securities; (ii) default in payment of any principal (including, without limitation, any premium, if any) on the Securities when due (whether at maturity, upon redemption, on a Change in Control Purchase Date or otherwise); (iii) failure by the Company for 60 days after notice to it to comply with any of its other agreements contained in the Indenture or the Securities; (iv) failure by the Company to give notice to the Trustee and Holders of a Change in Control in accordance with the Indenture; and (v) certain events of bankruptcy, insolvency or reorganization of the Company. If an Event of Default (other than as a result of certain events of bankruptcy, insolvency or reorganization of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities then outstanding may declare all unpaid principal to the date of acceleration on the Securities then outstanding to be due and payable immediately, all as and to the extent provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, unpaid principal of the Securities then outstanding shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interests. The Company is required to file periodic reports with the Trustee as to the absence of Default. 16. Trustee Dealings with the Company --------------------------------- The Bank of New York, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee. 17. No Recourse Against Others -------------------------- A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture nor for any claim based on, in respect of or by reason of such obligations or their creation. The Holder of this Security by accepting this Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security. A-7

18.
