Capitalized terms used herein or on the face hereof and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the TIA for a statement of those terms. The Securities are general, unsecured obligations of the Company limited to the aggregate Principal Amount specified in Section 2.02 of the Indenture (subject to Section 2.07 of the Indenture).

Such Purchase Price (equal to the Issue Price plus accrued Original Issue Discount through such Purchase Date) may be paid, at the option of the Company, in cash or by the issuance and delivery of shares of Common Stock of the Company, or in any combination thereof. Purchase Date Purchase Price ------------- -------------- August 19, 2002 $594.25 August 19, 2007 $706.82 August 19, 2012 $840.73 Subject to the terms and conditions of the Indenture, if any Change of Control occurs on or prior to August 19, 2002, the Company shall, at the option of the Holder, purchase all Securities for which a Change of Control Purchase Notice shall have been delivered as provided in the Indenture and not withdrawn, on the date that is 35 Business Days after the occurrence of such Change of Control, for a Change of Control Purchase Price equal to the Issue Price, plus accrued Original Issue Discount through the Change of Control Purchase Date, which Change of Control Purchase Price shall be paid in cash. Holders have the right to withdraw any Purchase Notice or Change of Control Purchase Notice, as the case may be, by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture prior to the close of business on the Purchase Date or Change of Control Purchase Date, as the case may be. If cash sufficient to pay the Purchase Price or Change of Control Purchase Price of all Securities or portions thereof to be purchased as of the Purchase Date or the Change of Control Purchase Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Purchase Date or the Change of Control Purchase Date, as the case may be, Original Issue Discount ceases to accrue on such Securities (or portions thereof) on and after such date, and the Holders thereof shall have no other rights as such (other than the right to receive the Purchase Price or Change of Control Purchase Price, as the case may be, upon surrender of such Security). 7. NOTICE OF REDEMPTION Notice of redemption will be mailed at least 20 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on and after such date Original Issue Discount ceases to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of Principal Amount may be redeemed in part but only in integral multiples of $1,000 of Principal Amount. 8. CONVERSION Subject to the next two succeeding sentences, a Holder of a Security may convert it into Common Stock of the Company at any time before the close of business on August 19, 2017; PROVIDED, HOWEVER, that if a Security is called for redemption, the Holder may convert it at any time before the close of business on the date that is seven days prior to the Redemption Date. The number of shares of Common Stock to be delivered upon conversion of a Security into Common Stock per $1,000 of Principal Amount shall be equal to the Conversion Rate. A Security in respect of which a Holder has delivered a Purchase Notice or Change of Control Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if the notice of exercise is withdrawn in accordance with the terms of the Indenture. The initial Conversion Rate is 11.3545 shares of Common Stock per $1,000 Principal Amount, subject to adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock. To convert a Security a Holder must (i) complete and manually sign the conversion notice on the back of the Security (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent (or the office or agency referred to in Section 4.05 of the Indenture), (ii) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (iii) pay any transfer or similar tax, if required. If the 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 total Principal Amount of the Securities converted. A Holder may convert a portion of a Security if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment will be made for dividends on the Common Stock, except as provided in the Indenture. On conversion of a Security, that portion of accrued Original Issue Discount attributable to the period from the Issue Date to the Conversion Date with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed paid in full to the Holder thereof through the delivery of the Common Stock in exchange for the Security being converted pursuant to the terms hereof, and the fair market value of such Common Stock (together with any cash payment in lieu of fractional shares of Common Stock) shall be treated as issued, to the extent thereof, first in exchange for Original Issue Discount accrued through the Conversion Date, and the balance, if any, of such fair market value of such shares of Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof. The Conversion Rate will be adjusted for dividends or distributions on Common Stock payable in Common Stock or other Capital Stock; subdivisions, combinations or certain reclassifications of Common Stock; distributions to all holders of Common Stock of certain rights to purchase Common Stock for a period expiring within 60 days at less than the Market Price at the Time of Determination; and distributions to such holders of assets or debt securities of the Company or certain rights to purchase securities of the Company (excluding certain cash dividends or distributions). However, no adjustment need be made if Securityholders may participate in the transaction or in certain other cases. The Company from time to time may voluntarily increase the Conversion Rate. If the Company is a party to a consolidation, merger or binding share exchange of the type specified in the Indenture, or certain transfers of all or substantially all of its assets to another person, or in certain other circumstances described in the Indenture, the right to convert a Security into Common Stock may be changed into a right to convert it into securities, cash or other assets of the Company or another person. 9. CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION Any Securities called for redemption, unless surrendered for conversion before 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 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 and to make payment for such Securities to the Trustee in trust for such Holders. 10. DENOMINATIONS; TRANSFER; EXCHANGE The Securities are in fully registered form, without coupons, in denominations of $1,000 of Principal Amount and integral multiples of $1,000. A Holder may transfer 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 and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities in respect of which a Purchase Notice or Change of Control Purchase Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before a selection of Securities to be redeemed. 11. PERSONS DEEMED OWNERS The registered Holder of this Security may be treated as the owner of this Security for all purposes. 12. UNCLAIMED MONEY OR SECURITIES The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, PROVIDED, HOWEVER, that at the Company's request, the Trustee or such Paying Agent, before being required to make any such return, shall at the expense of the Company cause to be published once in THE WALL STREET JOURNAL or another newspaper of national circulation or mail to each such Holder notice that such money or securities remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing, any unclaimed money or securities then remaining will be returned to the Company. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person, and the Trustee and the Paying Agent shall have no further liability with respect to such money or securities for that period commencing after the return thereof. 13. AMENDMENT; WAIVER Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate Principal Amount of the Securities at the time outstanding and (ii) certain defaults or noncompliance with certain provisions may be waived with the written consent of the Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to cure any ambiguity, defect or inconsistency, or to comply with Article 5 or Section 10.14 of the Indenture or to make any change that does not adversely affect the rights of any Securityholder. 14. DEFAULTS AND REMEDIES Under the Indenture, Events of Default include (i) default in payment of the Principal Amount, Issue Price, accrued Original Issue Discount, Redemption Price, Purchase Price or Change of Control Purchase Price, as the case may be, in respect of the Securities when the same becomes due and payable; (ii) failure either to deliver shares of Common Stock (or cash in lieu of fractional shares) in accordance with the terms of the Indenture when such Common Stock (or cash in lieu of fractional shares) is required to be delivered following conversion of a Security and such failure is not remedied for a period of 10 days; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, subject to notice and lapse of time; (iv) default (A) in the payment of any principal on any debt for borrowed money of the Company, in an aggregate principal amount in excess of $10 million when due at its final maturity, or (B) in the performance of any term or provision of any debt for borrowed money of the Company in an aggregate principal amount in excess of $10 million that results in such debt becoming or being declared due and payable prior to the date on which it would otherwise become due and payable; or (v) certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate Principal Amount of the Securities at the time outstanding, may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default that will result in the Securities becoming due and payable immediately upon the occurrence of such Events of Default. Securityholders may not enforce the Indenture or the Securities, except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in aggregate Principal Amount of the Securities at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i) above) if it determines that withholding notice is in their interests. 15. TRUSTEE DEALINGS WITH THE COMPANY Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. 16. NO RECOURSE AGAINST OTHERS A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 17. ADDITIONAL RIGHTS OF HOLDERS OF TRANSFER RESTRICTED SECURITIES In addition to the rights provided to Holders of Securities under the Indenture, Holders of Securities shall have all the rights set forth in the Registration Rights Agreement. 18. SUBORDINATION The Securities are subordinated to Senior Indebtedness (as defined in the Indenture), and all obligations of the Company with respect to the Senior Indebtedness. To the extent provided in the Indenture, Senior Indebtedness must be paid before the Securities may be paid. The Company agrees, and each Holder by accepting a Security consents and agrees, to the subordination provided in the Indenture and authorizes the Trustee to give it effect. 19.
