McKereghan Title: Secretary TRUSTEE'S CERTIFICATE OF AUTHENTICATION This is one of the Securities referred to in the within-mentioned Indenture. Dated: WELLS FARGO BANK, NATIONAL ASSOCIATION, as Trustee By: _________________________________________________ Authorized Signatory [FORM OF REVERSE] This Security is one of a duly authorized issue of securities of the Company designated as its "4.25% Convertible Subordinated Notes due July 1, 2008" (herein called the "Securities"), limited in aggregate principal amount to U.S. $[__________], issued and to be issued under an Indenture, dated as of June 13, 2003 (herein called the "Indenture"), between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the holders of Senior Debt and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities of any authorized denominations as requested by the Holder surrendering the same upon surrender of the Security or Securities to be exchanged, at the Corporate Trust Office of the Trustee. The Trustee upon such surrender by the Holder will issue the new Securities in the requested denominations. No sinking fund is provided for the Securities. The Company may not redeem the Securities prior to July 5, 2005. The Securities are subject to redemption at the option of the Company at any time on or after July 5, 2005, in whole or in part, at a Redemption Price equal to 100% of the principal amount (provided, however, that if the Redemption Date is before July 1, 2007, the Company may redeem the Securities only if the Closing Price Per Share of the Company's Common Stock exceeds 140% of the Conversion Price for at least 20 Trading Days in any consecutive 30 day trading period upon not less than 30 nor more than 60 days' notice to the Holders prior to the Redemption Date) at a Redemption Price equal to 100% of the principal amount, together with accrued interest to, but excluding, the Redemption Date; provided, however, that interest installments on Securities whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. In the event of a redemption of the Securities, the Company will not be required (a) to register the transfer or exchange of Securities for a period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption or (b) to register the transfer or exchange of any Security, or portion thereof, called for redemption. In any case where the due date for the payment of the principal of, premium, if any, interest, or Liquidated Damages on any Security or the last day on which a Holder of a Security has a right to convert his Security shall be, at any Place of Payment or Place of Conversion as the case may be, a day on which banking institutions at such Place of Payment or Place of Conversion are authorized or obligated by law or executive order to close, then payment of principal, premium, if any, interest, or Liquidated Damages, or delivery for conversion of such Security need not be made on or by such date at such place but may be made on or by the next succeeding day at such place which is not a day on which banking institutions are authorized or obligated by law or executive order to close, with the same force and effect as if made on the date for such payment or the date fixed for redemption or repurchase, or by such last day for conversion, and no interest shall accrue on the amount so payable for the period after such date. Subject to and upon compliance with the provisions of the Indenture, the Holder of this Security is entitled, at his option, at any time on or before the close of business on the date of Maturity, or in case this Security or a portion hereof is called for redemption or the Holder hereof has exercised his right to require the Company to repurchase this Security or such portion hereof, then in respect of this Security until the Business Day immediately preceding, but (unless the Company defaults in making the payment due upon redemption or repurchase, as the case may be) not after, the close of business on the Business Day immediately preceding the Redemption Date or the Repurchase Date, as the case may be, to convert this Security (or any portion of the principal amount hereof that is an integral multiple of U.S.$1,000, provided that the unconverted portion of such principal amount is U.S.$1,000 or any integral multiple of U.S.$1,000 in excess thereof) into fully paid and nonassessable shares of Common Stock of the Company at an initial Conversion Rate of 108.9918 shares of Common Stock for each U.S.$1,000 principal amount of Securities (or at the current adjusted Conversion Rate if an adjustment has been made as provided in the Indenture) by surrender of this Security, duly endorsed or assigned to the Company or in blank and, in case such surrender shall be made during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such succeeding Interest Payment Date (except if this Security or portion thereof has been called for redemption or if a Change in Control has occurred and an offer to repurchase the Securities is pending), also accompanied by payment in New York Clearing House or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of this Security then being converted, and also the conversion notice hereon duly executed, to the Company at the Corporate Trust Office of the Trustee, or at such other office or agency of the Company, subject to any laws or regulations applicable thereto and subject to the right of the Company to terminate the appointment of any Conversion Agent (as defined below) as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, or at such other offices or agencies as the Company may designate (each a "Conversion Agent"). The interest that is payable on such Interest Payment Date with respect to any Security (or portion thereof, if applicable) that is surrendered for conversion during the Record Date Period shall be paid to the Holder of such Security as of such Regular Record Date in an amount equal to the interest that would have been payable on such Security if such Security had been converted as of the close of business on such Interest Payment Date. Subject to the provisions of the preceding sentence and, in the case of a conversion after the close of business on the Regular Record Date next preceding any Interest Payment Date and on or before the close of business on such Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security of record as of such Regular Record Date) to receive the related installment of interest to the extent and under the circumstances provided in the Indenture, no cash payment or adjustment is to be made on conversion for interest accrued hereon from the Interest Payment Date next preceding the day of conversion, or for dividends on the Common Stock issued on conversion hereof. The Company shall thereafter deliver to the Holder the fixed number of shares of Common Stock (together with any cash adjustment, as provided in the Indenture) into which this Security is convertible and such delivery will be deemed to satisfy the Company's obligation to pay the principal amount of this Security. No fractions of shares or scrip representing fractions of shares will be issued on conversion, but instead of any fractional interest (calculated to the nearest 1/100th of a share) the Company shall pay a cash adjustment as provided in the Indenture. The Conversion Rate is subject to adjustment as provided in the Indenture. In addition, the Indenture provides that in case of certain consolidations or mergers to which the Company is a party (other than a consolidation or merger that does not result in any reclassification, conversion, exchange or cancellation of the Common Stock) or the conveyance, transfer, sale or lease of all or substantially all of the property and assets of the Company, the Indenture shall be amended, without the consent of any Holders of Securities, so that this Security, if then Outstanding, will be convertible thereafter, during the period this Security shall be convertible as specified above, only into the kind and amount of securities, cash and other property receivable upon such consolidation, merger, conveyance, transfer, sale or lease by a holder of the number of shares of Common Stock of the Company into which this Security could have been converted immediately prior to such consolidation, merger, conveyance, transfer, sale or lease (assuming such holder of Common Stock is not a Constituent Person or an Affiliate of a Constituent Person, failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of Non-electing Shares). No adjustment in the Conversion Rate will be made until such adjustment would require an increase or decrease of at least one percent of such rate, provided that any adjustment that would otherwise be made will be carried forward and taken into account in the computation of any subsequent adjustment. If this Security is a Registrable Security (as defined in the Indenture), then the Holder of this Security (including any Person that has a beneficial interest in this Security) and the Common Stock of the Company issuable upon conversion hereof is entitled to the benefits of a Registration Rights Agreement, dated as of June 13, 2003, executed by the Company (the "Registration Rights Agreement"). Pursuant to the Registration Rights Agreement, the Company has agreed for the benefit of the Holders from time to time of the Registrable Securities that it will, at its expense, (a) within 90 days after the Issue Date file a shelf registration statement (the "Shelf Registration Statement") with the Commission with respect to resales of the Registrable Securities, (b) use its reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission within 180 days after the Issue Date, provided, however, that the Company may, upon written notice to all the Holders, postpone having the Shelf Registration Statement declared effective for a reasonable period not to exceed 90 days if the Company possesses material non-public information, the disclosure of which would have a material adverse effect on the Company and its subsidiaries taken as a whole, and (c) use its reasonable efforts to maintain such Shelf Registration Statement effective under the Securities Act of 1933, as amended, until the second annual anniversary of the Issue Date or, if earlier, until there are no outstanding Registrable Securities (the "Effectiveness Period"). The Company will be permitted to suspend the use of the prospectus which is part of the Shelf Registration Statement during certain periods of time as provided in the Registration Rights Agreement. If (i) on or prior to 90 days following the Issue Date, a Shelf Registration Statement has not been filed with the Commission, or (ii) on or prior to the 180th day following the Issue Date, such Shelf Registration Statement is not declared effective (each, a "Registration Default"), additional interest ("Liquidated Damages") will accrue on the Registrable Securities from and including the day following such Registration Default to but excluding the day on which such Registration Default has been cured. Liquidated Damages will be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date, as applicable, in respect of the Registrable Securities following the date on which such Liquidated Damages begin to accrue, and will accrue at a rate per annum equal to one-quarter of one percent (0.25%) of the principal amount of the Registrable Securities to and including the 90th day following such Registration Default and at a rate per annum equal to one-half of one percent (0.50%) thereof from and after the 91st day following such Registration Default. Pursuant to the Registration Rights Agreement, in the event that the Shelf Registration Statement ceases to be effective (or the Holders of Registrable Securities are otherwise prevented or restricted by the Company from effecting sales pursuant thereto) (an "Effective Failure") during the Effectiveness Period for more than 45 days, whether or not consecutive, during any 90-day period or for more than 90 days, whether or not consecutive, during any 365-day period, then the interest rate borne by the Registrable Securities shall increase by an additional one-quarter of one percent (0.25%) per annum from the 46th day of the applicable 90-day period or shall increase by an additional one-half of one percent (0.50%) per annum from the 91st day of the applicable 365-day period until the earlier of (A) such time as the Effective Failure is cured or (B) the Effectiveness Period expires. Liquidated Damages will accrue (1) with respect to a Restricted Security at the rates set forth above, as applicable, on the principal amount of the Restricted Securities and (2) in respect of the Common Sock issued upon conversion of the Restricted Securities, at the rates set forth above, as applicable, applied to the Conversion Price at that time. In no event shall the Company be required to pay Liquidated Damages in excess of the applicable maximum amount of one-half of one percent (0.5%) set forth above regardless of whether one or multiple Registration Defaults exist. Whenever in this Security there is a reference, in any context, to the payment of the principal of, premium, if any, or interest on, or in respect of, any Security, such mention shall be deemed to include mention of the payment of Liquidated Damages payable as described in the preceding paragraph to the extent that, in such context, Liquidated Damages are, were or would be payable in respect of such Security and express mention of the payment of Liquidated Damages (if applicable) in any provisions of this Security shall not be construed as excluding Liquidated Damages in those provisions of this Security where such express mention is not made. If this Security is a Registrable Security and the Holder of this Security (including any Person that has a beneficial interest in this Security) elects to sell this Security pursuant to the Shelf Registration Statement then, by its acceptance hereof, such Holder of this Security agrees to be bound by the terms of the Registration Rights Agreement relating to the Registrable Securities which are the subject of such election. If a Change in Control occurs, the Holder of this Security, at the Holder's option, shall have the right, in accordance with the provisions of the Indenture, to require the Company to repurchase this Security (or any portion of the principal amount hereof that is at least $1,000 or an integral multiple of $1,000 in excess thereof, provided that the portion of the principal amount of this Security to be Outstanding after such repurchase is at least equal to U.S.$1,000) for cash at a Repurchase Price equal to 100% of the principal amount thereof plus interest accrued to the Repurchase Date. Whenever in this Security there is a reference, in any context, to the principal of any Security as of any time, such reference shall be deemed to include reference to the Repurchase Price payable in respect of such Security to the extent that such Repurchase Price is, was or would be so payable at such time, and express mention of the Repurchase Price in any provision of this Security shall not be construed as excluding the Repurchase Price so payable in those provisions of this Security when such express mention is not made. In the event of a deposit or withdrawal of an interest in this Security, including an exchange, transfer, redemption, repurchase or conversion of this Security in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit or withdrawal in accordance with the Applicable Procedures. The indebtedness evidenced by this Security is, to the extent and in the manner provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Debt of the Company, and this Security is issued subject to such provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. If an Event of Default shall occur and be continuing, the principal of all the Securities, together with accrued interest to the date of declaration, may be declared due and payable in the manner and with the effect provided in the Indenture. Upon payment (i) of the amount of principal so declared due and payable, together with accrued interest to the date of declaration, and (ii) of interest on any overdue principal and, to the extent permitted by applicable law, overdue interest, all of the Company's obligations in respect of the payment of the principal of and interest on the Securities shall terminate. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company and the Trustee with either (a) the written consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding, or (b) by the adoption of a resolution, at a meeting of Holders of the Outstanding Securities at which a quorum is present, by the Holders of at least 66 2/3% in aggregate principal amount of the Outstanding Securities represented and entitled to vote at such meeting. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities at the time Outstanding, on behalf of the Holders of all the Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued in exchange therefore or in lieu hereof whether or not notation of such consent or waiver is made upon this Security or such other Security. Certain modifications or amendments to the Indenture require the consent of the Holder of each Outstanding Security affected. As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default, the Holders of not less than 25% in principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall not have received from the Holders of a majority in principal amount of the Securities Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof, premiums if any, or interest (including Liquidated Damages) hereon on or after the respective due dates expressed herein or for the enforcement of the right to convert this Security as provided in the Indenture. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest (including Liquidated Damages) on this Security at the times, places and rate, and in the coin or currency, herein prescribed or to convert this Security as provided in the Indenture. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable on the Security Register upon surrender of this Security for registration of transfer at the Corporate Trust Office of the Trustee or at such other office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York (which shall initially be an office or agency of the Trustee), or at such other offices or agencies as the Company may designate, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Securities, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees by the Registrar. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to recover any tax or other governmental charge payable in connection therewith. Prior to due presentation of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered, as the owner thereof for all purposes, whether or not such Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. No recourse for the payment of the principal (and premium, if any) or interest on this Security and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Security, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of consideration for the issue hereof, expressly waived and released.
