TRUSTEE'S CERTIFICATE OF AUTHENTICATION JPMORGAN CHASE BANK, as Trustee, certifies that this is one of the Securities referred to in the within-mentioned Indenture. By: /s/ Carol Ng ------------------------------------------------ Authorized Officer Dated: August 12, 2003 ---------------- 4.125% Series A Convertible Senior Debentures due 2023 This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities") limited in aggregate Original Principal Amount to $40,000,000 Original Principal Amount, issued under an Indenture, dated as of August 12, 2003 (the "Indenture"), between the Company and JPMorgan Chase Bank, as Trustee (the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Capitalized terms used and not otherwise defined in this Security are used as defined in the Indenture. 1. Interest. This Security will bear interest from August 12, 2003 or from the most recent date to which interest has been paid or duly provided for, semi-annually in arrears on February 15 and August 15 of each year (each, an "Interest Payment Date"), subject to Section 1.08 of the Indenture, commencing February 15, 2004, at the rate per annum equal to 4.125%, to but excluding August 15, 2010. Interest on this Security shall be calculated on the basis of a 360-day year composed of twelve 30-day months. Interest payable on this Security on any Interest Payment Date will include interest for the immediately preceding Interest Period. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the February 1 or August 1, as the case may be, immediately preceding the relevant Interest Payment Date. Any interest which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the registered Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and may be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Company, notice whereof shall be given to the Holders of Securities not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. From and after August 15, 2010, the Company will no longer be required to pay cash interest. The Original Principal Amount of this Security shall accrete daily at the Applicable Yield on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months. The Applicable Yield shall be 0% prior to August 15, 2010 and 4.125% per annum on and after April 15, 2010, until Stated Maturity. At Stated Maturity, the Holder of this Security will receive $1,700.28 for each $1,000 Original Principal Amount of Securities, which is the fully Accreted Principal Amount of this Security on such date, unless the Security has been earlier redeemed, purchased or converted. 2. Contingent Interest. From and after August 20, 2010, the Company will pay Contingent Interest on this Security under the circumstances and in the amounts described in Article 14 of the Indenture. Such Contingent Interest, if any, shall be payable semiannually in arrears on each Interest Payment Date to the Holder of this Security as of the close of business on the Regular Record Date relating to such Interest Payment Date. 3. Interest on Overdue Amounts. If the Accreted Principal Amount hereof or any portion of such Accreted Principal Amount is not paid when due (whether upon acceleration pursuant to Section 4.02 of the Indenture, upon the dates set for payment of the Redemption Price, Purchase Price or Fundamental Change Purchase Price, or upon the Stated Maturity of this Security) or if interest due hereon (including Contingent Interest and Liquidated Damages, if any) (or any portion of such interest), is not paid when due, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate then borne by this Security or, if any overdue amount exists on or after August 15, 2010, at the Applicable Yield of this Security, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable as set forth in the Indenture. 4. Method of Payment. Subject to the terms and conditions of the Indenture, the Company will make payments in respect of Redemption Price, Purchase Price, Fundamental Change Purchase Price and at Stated Maturity to Holders who surrender Securities to a Paying Agent to collect such payments in respect of the Securities. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such cash payments by check payable in such money; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest (including Contingent Interest and Liquidated Damages, if any) on all Global Securities and all Securities of Holders of more than $25,000,000 aggregate Original Principal Amount of Securities that have requested such method of payment and provided wire transfer instructions to the Company or the Paying Agent. If any Interest Payment Date (other than an Interest Payment Date coinciding with the Stated Maturity or earlier Redemption Date, Purchase Date, or Fundamental Change Purchase Date) falls on a day that is not a Business Day, such Interest Payment Date will be postponed to the next succeeding Business Day and no interest on such payment will accrue for the period from and after the Interest Payment Date to such next succeeding Business Day, provided that, if such Business Day falls in the next succeeding calendar month, the Interest Payment Date will be the Business Day immediately preceding such Interest Payment Date. If the Stated Maturity, Redemption Date, Purchase Date or Fundamental Change Purchase Date of this Security would fall on a day that is not a Business Day, the required payment of interest, if any, and principal will be made on the next succeeding Business Day and no interest on such payment will accrue and no principal will accrete for the period from and after the Stated Maturity, Redemption Date, Purchase Date or Fundamental Change Purchase Date to such next succeeding Business Day. 5. Paying Agent, Conversion Agent and Registrar. Initially, the Trustee will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent, Registrar or co-registrar without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Registrar or co-registrar. 6. Indenture. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect from time to time (the "TIA"). The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of those terms. The Securities are general unsecured obligations. The Indenture does not limit other indebtedness of the Company. 7. Redemption at the Option of the Company. No sinking fund is provided for the Securities. Prior to August 20, 2010, the Securities shall not be redeemable at the option of the Company. Beginning on August 20, 2010 and until the Stated Maturity, the Securities are redeemable for Cash as a whole, or from time to time in part, at the option of the Company at the applicable Redemption Price. If the Company redeems less than all of the outstanding Securities, the Trustee will select the Securities to be redeemed (i) by lot; (ii) pro rata; or (iii) by another method the Trustee considers fair and appropriate. If the Trustee selects a portion of a Holder's Securities for partial redemption and the Holder converts a portion of the same Securities, the converted portion shall be deemed to be from the portion selected for redemption. 8. Notice of Redemption. Notice of redemption will be mailed at least 30 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, immediately after such Redemption Date interest shall cease to accrue and principal will cease to accrete on such Securities or portions thereof. Securities in denominations larger than $1,000 Original Principal Amount may be redeemed in part but only in integral multiples of $1,000. 9. Purchase By the Company at the Option of the Holder. Each Holder has the right to require the Company to purchase the Securities held by such Holder on August 15, 2010, 2015 and 2020 (each, a "Purchase Date"). If required by any Holder, the Company shall purchase Securities for Cash, Common Stock or any combination of Cash and Common Stock at a Purchase Price equal to the Accreted Principal Amount thereof, plus accrued and unpaid cash interest (including Contingent Interest and Liquidated Damages, if any) to, but excluding, the Purchase Date, upon delivery of a Purchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business Days prior to such Purchase Date until the close of business on the Business Day immediately preceding such Purchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture. At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall purchase for Cash, Common Stock or any combination of Cash and Common Stock all or a portion of the Securities held by such Holder as of the date that is not less than 20 nor more than 35 Business Days after the date of the Company's notice to Holders of the occurrence of a Fundamental Change occurring prior to Stated Maturity for a Fundamental Change Purchase Price equal to the Accreted Principal Amount thereof, plus accrued and unpaid cash interest (including Contingent Interest and Liquidated Damages, if any) to, but excluding, the Fundamental Change Purchase Date, unless such Fundamental Change Purchase Date falls after a Regular Record Date and on or prior to the corresponding Interest Payment Date, in which case the Company shall pay the full amount of accrued and unpaid cash interest (including Contingent Interest and Liquidated Damages, if any) payable on such Interest Payment Date to the Holder at the close of business on such Regular Record Date. Holders have the right to withdraw any Purchase Notice or Fundamental Change 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. As provided in the Indenture, if Cash or Common Stock (or any combination of Cash and Common Stock) sufficient to pay the Purchase Price or Fundamental Change Purchase Price, as the case may be, of all Securities or portions thereof to be purchased as of the Purchase Date or the Fundamental Change Purchase Date, as the case may be, is deposited with the Paying Agent on the Purchase Date or the Fundamental Change Purchase Date, as the case may be, all interest (including Contingent Interest and Liquidated Damages, if any) ceases to accrue and principal ceases to accrete on such Securities (or portions thereof) immediately after such Purchase Date or Fundamental Change Purchase Date, as the case may be, and the Holder thereof shall have no other rights as such (other than the right to receive the Purchase Price or Fundamental Change Purchase Price, as the case may be, upon surrender of such Security). 10. Conversion. Subject to the terms of the Indenture, the Holder of a Security may convert the Security into shares of Common Stock at the Conversion Rate under the circumstances set forth in Section 11.01 of the Indenture; provided, however, the Company may satisfy its obligation with respect to any demand for conversion by delivering Common Stock, Cash or a combination of Cash and Common Stock. The Conversion Rate for the Securities on any Conversion Date shall be determined as set forth in the Indenture. Upon conversion of a Security, the Company shall deliver the Conversion Settlement Distribution within the time periods set forth in Section 11.02 of the Indenture. A Security in respect of which a Holder has delivered a Purchase Notice or a Fundamental Change Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture. The Company shall deliver Cash or a check in lieu of any fractional share of Common Stock. A Holder's right to convert the Securities into Common Stock of the Company is also subject to the Company's right to elect pursuant to Section 11.03 of the Indenture to pay such Holder Cash in lieu of delivering all or part of such Common Stock. A Holder may convert a portion of a Security if the Original Principal Amount of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment shall be made for dividends on the Common Stock except as provided in the Indenture. On conversion of a Security, except for conversion during the period from the close of business on any Regular Record Date immediately preceding any Interest Payment Date to the opening of business on such Interest Payment Date, in which case the Holder on such Regular Record Date shall receive the interest payable on such Interest Payment Date, that portion of accrued and unpaid interest (including Contingent Interest, if any) and any accretion of principal on the converted Security attributable to the period from the most recent Interest Payment Date (or, if no Interest Payment Date has occurred, from the Issue Date) through the Conversion Date shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of the Common Stock (together with the Cash payment, if any, in lieu of fractional shares), or Cash or a combination of Cash and Common Stock in lieu thereof, in exchange for the Security being converted pursuant to the provisions hereof. Securities or portions thereof surrendered for conversion during the period from the close of business on any Regular Record Date immediately preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall be accompanied by payment to the Company or its order, in New York Clearing House funds or other funds acceptable to the Company, of an amount equal to the interest payable on such Interest Payment Date with respect to the Original Principal Amount of Securities or portions thereof being surrendered for conversion; provided that no such payment need be made (1) if the Company has specified a Redemption Date that occurs during the period from the close of business on a Regular Record Date to the opening of business on the Interest Payment Date to which such Regular Record Date relates, (2) if the Company has specified a Fundamental Change Purchase Date during such period, (3) with respect to any Liquidated Damages payable on such Interest Payment Date or (4) if any overdue interest or overdue Contingent Interest exists on the Conversion Date with respect to the Securities converted, to the extent of such overdue interest. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in Cash pursuant to Section 11.04 of the Indenture. The Company agrees, and by acceptance of a beneficial interest in a Security each Holder and any beneficial owner of a Security shall be deemed to agree to be bound (in the absence of an administrative determination or judicial ruling to the contrary) by the Company's determination of the comparable yield and projected payment schedule within the meaning of the contingent debt regulations, and accordingly shall treat, for United States federal income tax purposes, the fair market value of the Common Stock received upon the conversion of a Security (together with any Cash payment in lieu of fractional shares) or Cash in lieu thereof, or a combination of Cash and Common Stock as a contingent payment on the Security for purposes of Treasury Regulation Section 1.1275-4 or any successor provision. To convert a Security, a Holder must fulfill the conditions set forth in Section 11.02 of the Indenture. The Conversion Rate will be adjusted as set forth in Article 11 of the Indenture. 11. Denominations; Transfer; Exchange. The Securities are in fully registered form, without coupons, in denominations of $1,000 of Original 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 Fundamental Change 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 the mailing of a notice of redemption of Securities to be redeemed. 12. Persons Deemed Owners. The registered Holder of this Security may be treated as the owner of this Security for all purposes. 13. 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 subject to applicable unclaimed property law. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person. 14. 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 Original Principal Amount of the Securities at the time outstanding and (ii) certain Defaults may be waived with the written consent of the Holders of a majority in aggregate Original Principal Amount of the Securities at the time outstanding. The Company and the Trustee may amend the Indenture under certain circumstances without the consent of the Holders, as described in the Indenture. 15. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate Original Principal Amount of the Securities then outstanding, may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities becoming due and payable immediately upon the occurrence of such Events of Default. Holders 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 Original 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 Holders notice of any continuing Default (except a Default in payment on any Security) if it determines that withholding notice is in their interests. 16. 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. 17. 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 Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities. 18. Authentication. This Security shall not be valid until an authorized signatory of the Trustee manually signs the Trustee's Certificate of Authentication on the other side of this Security. 19. Abbreviations. Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act). 20. GOVERNING LAW. THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN THE INDENTURE AND THIS SECURITY, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS. ---------------------------- The Company will furnish to any Holder upon written request and without charge a copy of the Indenture.
