There shall be a series of Securities designated "Zero Coupon Convertible Senior Debentures Due June 30, 2020" of the Company, and the form thereof shall be substantially as set forth in Annex A hereto, which is incorporated into and shall be deemed a part of this Second Supplemental Indenture, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers of the Company executing such 2020 Debentures, as evidenced by their execution of the 2020 Debentures. (a) Restricted Global Securities. All of the 2020 Debentures are initially being offered and sold to qualified institutional buyers as defined in Rule 144A (collectively, "QIBs" or individually a "QIB") in reliance on Rule 144A under the Securities Act and shall be issued initially in the form of one or more Restricted Global Securities, which shall be deposited on behalf of the purchasers of the 2020 Debentures represented thereby with the Trustee, at its Corporate Trust Office, as security custodian ("Security Custodian") for the depositary, The Depository Trust Company ("DTC"), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. The Depositary shall be a clearing agency registered under the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"). Each Global Security in global form, to the extent that it represents the interests of Non-U.S. Persons, will be held by Cede & Co. for the accounts of designated agents on behalf of the Euroclear System ("Euroclear") and Clearstream Banking, Societe Anonyme ("Clearstream"). During the 40-day distribution compliance period (as defined in Regulation S), Non-U.S. Persons holding beneficial interests in a Security in global form may do so only through Euroclear or Clearstream, and any resale or transfer of any such interest to a U.S. Person shall only be permitted if such Person is a QIB or is the Company or an Affiliate of the Company. The aggregate Principal Amount of a Restricted Global Security may from time to time be increased or decreased by adjustments made on the records of the Security Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures. 2 6 (b) Global Securities in General. Each Global Security shall represent such of the outstanding 2020 Debentures as shall be specified therein and each shall provide that it shall represent the aggregate amount of Outstanding 2020 Debentures from time to time endorsed thereon and that the aggregate amount of Outstanding 2020 Debentures represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, purchases or conversions of such 2020 Debentures. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the Principal Amount of Outstanding 2020 Debentures represented thereby shall be made by the Security Custodian in accordance with the standing instructions and procedures existing between the Depositary and the Security Custodian. Members of, or participants in, the Depositary ("Agent Members") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (B) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any 2020 Debenture. Any Global Security may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Indenture as may be required by the Security Custodian, the Depositary or by the National Association of Securities Dealers, Inc. in order for such Securities to be tradeable on any market developed for trading of securities pursuant to Rule 144A or Regulation S or required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange or automated quotation system upon which the Securities may be listed or traded or to conform with any usage with respect thereto, or to indicate any special limitations or restrictions to which any particular Securities are subject. (c) Certificated Securities. Certificated Securities shall be issued only under the limited circumstances provided in Section 102(a)(1) hereof. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Securities. The Company initially appoints the Trustee to act as Paying Agent, Security Registrar and Conversion Agent with respect to the 2020 Debentures. 3 7 SECTION 102 Transfer and Exchange.

Only Restricted Certificated Securities shall be issued in exchange for beneficial interests in Restricted Global Securities, and only Unrestricted Certificated Securities shall be issued in exchange for beneficial interests in Unrestricted Global Securities.

The Indenture is hereby amended, subject to Section 201 hereof and with respect to the 2020 Debentures only, by adding the following Articles FIFTEEN, SIXTEEN, SEVENTEEN and EIGHTEEN to the Indenture: ARTICLE FIFTEEN CONVERSION SECTION 1501 Conversion Privilege. 2020 Debentures shall be convertible in accordance with their terms and in accordance with this Article. A Holder of a 2020 Debenture may convert the Principal Amount of such 2020 Debenture (or any portion thereof equal to a Principal Amount of $1,000 or any integral multiple of a Principal Amount of $1,000 in excess thereof) into Common Stock at any time prior to the close of business on the date specified in the 2020 Debentures, at the Conversion Rate then in effect. In case a 2020 Debenture or portion thereof is called for redemption pursuant to Article ELEVEN, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Redemption Date for such 2020 Debenture or such earlier date as the Holder presents such 2020 Debenture for redemption (unless the Company shall default in making the redemption payment when due, in which case the 23 27 conversion right shall terminate at the close of business on the date such default is cured and such 2020 Debenture is redeemed). The number of shares of Common Stock issuable upon conversion of a 2020 Debenture per $1,000 of Principal Amount thereof (the "Conversion Rate") shall be that set forth under "Conversion" in the 2020 Debentures, subject to adjustment as herein set forth. Provisions of this Indenture that apply to conversion of all of a 2020 Debenture also apply to conversion of a portion of a 2020 Debenture. A 2020 Debenture in respect of which a Holder has delivered a Repurchase Notice or Fundamental Change Purchase Notice exercising the option of such Holder to require the Company to purchase such 2020 Debenture, may be converted only if such notice of exercise is withdrawn in accordance with the terms of this Indenture. A Holder of 2020 Debentures is not entitled to any rights of a holder of Common Stock until such Holder has converted its 2020 Debentures to Common Stock, and only to the extent such 2020 Debentures are deemed to have been converted into Common Stock pursuant to this Article FIFTEEN. SECTION 1502 Conversion Procedure. To convert a 2020 Debenture, a Holder must (a) complete and manually sign the conversion notice on the back of the 2020 Debenture and deliver such notice to a Conversion Agent, (b) surrender the 2020 Debenture to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by the Security 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 (and in any event no later than seven Business Days 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 and cash in lieu of any fractional shares pursuant to Section 1503. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such 2020 Debentures may be surrendered for conversion in accordance with the Applicable Procedures. 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 2020 Debenture on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or 24 28 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, however, that such conversion shall be at the Conversion Rate in effect on the date that such 2020 Debenture shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a 2020 Debenture, such Person shall no longer be a Holder of such 2020 Debenture. No payment or adjustment will be made for dividends on, or other distributions with respect to, any Common Stock except as provided in this Article FIFTEEN. On conversion of a 2020 Debenture, that portion of accrued Original Issue Discount (and interest, if the Company has exercised its option provided for in Section 1801) attributable to the period from the Issue Date (or, in the case of interest, if the Company has exercised the option provided for in Section 1801, the later of (x) the date of such exercise and (y) the date on which interest was last paid) of the 2020 Debenture through the Conversion Date with respect to the converted 2020 Debenture 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) in exchange for the 2020 Debenture being converted pursuant to the provisions hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall be treated as issued, to the extent thereof, first in exchange for Original Issue Discount (and interest, if the Company has exercised its option provided for in Section 1801) accrued through the Conversion Date, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the 2020 Debenture being converted pursuant to the provisions hereof. If a Holder converts more than one 2020 Debenture at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the aggregate Principal Amount of 2020 Debentures converted. 25 29 Upon surrender of a 2020 Debenture that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new 2020 Debenture equal in Principal Amount to the Principal Amount of the unconverted portion of the 2020 Debenture surrendered. Where the Company has exercised its option under Section 1801, 2020 Debentures 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 (unless such 2020 Debentures or portions thereof have been called for redemption on a Redemption Date within such period) 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 on the principal amount of 2020 Debentures or portions thereof being surrendered for conversion. SECTION 1503 Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of 2020 Debentures. In lieu thereof, the Company will 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 1504 Taxes on Conversion. If a Holder converts a 2020 Debenture, 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. 26 30 SECTION 1505 Company to Provide Common Stock. The Company shall, prior to issuance of any 2020 Debentures under this Article FIFTEEN, 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 2020 Debentures outstanding into shares of Common Stock. All shares of Common Stock delivered upon conversion of the 2020 Debentures 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 registration of the offer and delivery of shares of Common Stock to a converting Holder upon conversion of 2020 Debentures, 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 shares of Common Stock are then listed or quoted. SECTION 1506 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: (a) If the Company shall (i) pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide its outstanding Common Stock into a greater number of shares, (iii) combine its outstanding Common Stock into a smaller number of shares or (iv) issue by reclassification of its shares of Common Stock any shares of capital stock of the Company, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the Holder of any 2020 Debenture thereafter surrendered for conversion shall be entitled to receive that number of shares of capital stock of the Company which it would have owned had such 2020 Debenture been converted immediately prior to the occurrence 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, combination or reclassification (or immediately after the record date if a record date shall have been established for such event). If, as a result of an 27 31 adjustment made pursuant to this Section 1506(a), the Holder of any 2020 Debenture thereafter surrendered for conversion shall be entitled to receive shares of two or more classes or series of capital stock of the Company, the Board of Directors (whose determination shall be conclusive and shall be described in a Board Resolution filed with the Trustee) shall determine the allocation of the adjusted Conversion Rate for the 2020 Debentures between or among shares of such classes or series of capital stock. (b) If the Company shall issue rights or warrants to 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 45 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 (as determined in accordance with Section 1506(e)) on the record date for the determination of stockholders entitled to receive such rights or warrants, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to such record date by a fraction, of which the numerator shall be the number of shares of Common Stock outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered (or into which the convertible securities so offered are convertible), and of which the denominator 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 (as determined in accordance with Section 1506(e)) of Common Stock on such record date. Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after such record date. For the purposes of this Section 1506(b), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company shall not issue any rights or warrants in respect of shares of Common Stock held in the treasury of the Company. If at the end of the period during which such rights 28 32 or warrants are exercisable not all rights or warrants shall have been exercised, the adjusted Conversion Rate 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). To the extent that no shares of Common Stock are so delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. (c) Subject to the last sentence of this subsection (c), if the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock any shares of capital stock (other than dividends or distributions of Common Stock on Common Stock to which Section 1506(a) applies) of the Company, evidences of indebtedness or other assets (including securities of any Person other than the Company, but excluding all-cash distributions or any rights or warrants referred to in Section 1506(b)), then in each such case the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the current Conversion Rate in effect immediately prior to such distribution by a fraction, of which the numerator shall be the current market price per share (as determined in accordance with Section 1506(e)) of the Common Stock on the date fixed for the payment of such distribution mentioned below, and of which the denominator shall be the current market price per share (as determined in accordance with Section 1506(e)) of the Common Stock on such date fixed for the payment of such distribution less the fair market value on such date (as determined 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, other non-cash assets and cash 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 record date). Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately prior to the opening of business on the day after the date fixed for the payment of such distribution. If no such dividend or distribution is so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution 29 33 had not occurred. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 1506(c) by reference to the actual or when issued trading market for any securities comprising such distribution, in doing so it shall consider the prices in such market over the same period used in computing the current market price per share of Common Stock (determined as provided in Section 1506(e)). For purposes of this Section 1506(c), any dividend or distribution that includes shares of Common Stock or rights or warrants to subscribe for or purchase shares of Common Stock shall be deemed instead to be (i) a dividend or distribution of the evidences of indebtedness, shares of capital stock, cash or assets other than such shares of Common Stock or such rights or warrants (making any Conversion Rate adjustment required by this Section 1506(c)) immediately followed by (ii) a dividend or distribution of such shares of Common Stock or such rights or warrants (making any further Conversion Rate adjustment required by Section 1506(a) or 1506(b)), except (A) the date fixed for the payment of such dividend or distribution shall be substituted as (1) "the record date in the case of a dividend or other distribution," and (2) "the record date for the determination of stockholders entitled to receive such rights or warrants" and (3) "the date fixed for such determination" within the meaning of Sections 1506(a) and 1506(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed outstanding for purposes of computing any adjustment of the Conversion Rate in accordance with Section 1506(a). (d) (1) If the Company shall, by dividend or otherwise, at any time pay or make a dividend or distribution (a "Triggering Distribution") to the holders of its Common Stock exclusively in cash (excluding any quarterly cash dividend on Common Stock to the extent that the aggregate cash dividend per share of Common Stock in any quarter does not exceed the greater of (i) the amount per share of Common Stock of the next preceding quarterly dividend on Common Stock to the extent such preceding quarterly dividend did not require an adjustment of the Conversion Price pursuant to this Section 1506(d) (as adjusted to reflect subdivisions or combinations of Common Stock), and (ii) 3.75% of the current market price per share determined as provided in Section 1506(e), and excluding any dividend or distribution in connection with the liquidation, dissolution or winding-up of the Company), the Conversion Rate shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Rate in effect immediately prior to the effectiveness of the Conversion Rate adjustment contemplated by this 30 34 Section 1506(d)(1) by a fraction, of which the numerator shall be the current market price per share (determined as provided in Section 1506(e)) of the Common Stock on the date fixed for the payment of such distribution, and of which the denominator shall be such current market price per share of the Common Stock (determined as provided in Section 1506(e)), less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock. The adjustment to the Conversion Rate pursuant to this Section 1506(d)(1) shall become effective immediately prior to the opening of business on the day following the date fixed for the payment of such distribution; provided, however, that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the current market price per share (as defined in Section 1506(e)) of the Common Stock on the record date mentioned above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of shares of 2020 Debentures shall have the right to receive upon conversion the amount of cash such Holder would have received had such Holder converted each 2020 Debenture immediately prior to the record date for the distribution of the cash. If an adjustment is required to be made pursuant to this Section 1506(d)(1) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the quarterly cash dividend permitted to be excluded as provided above. If an adjustment is required to be made pursuant to this Section 1506(d)(1) as a result of a distribution that is not a quarterly dividend, such adjustment shall be based upon the full amount of the distribution. If no such dividend or distribution is so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such record date had not been fixed. (2) If any tender offer made by the Company or any of its Subsidiaries for all or any portion of the Company's Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall involve the payment by the Company or any such Subsidiary of aggregate consideration in an amount (determined at the last day that tenders may be made pursuant to such tender offer (as then amended, the "Expiration Date") as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as determined 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 31 35 consideration) that exceeds the current market price per share of Common Stock (as determined in accordance with Section 1506(e)) on the Business Day next succeeding the Expiration Date, then, immediately prior to the opening of business on the day after the Expiration Date, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Expiration Date by a fraction, of which the numerator 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 last time (the "Expiration Time") at which tenders could have been made on the Expiration Date (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 (excluding any Purchased Shares and any shares held in the treasury of the Company) at the Expiration Time and the current market price per share of Common Stock (as determined in accordance with Section 1506(e)) on the Trading Day next succeeding the Expiration Date, and of which the denominator 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 Common Stock (as determined in accordance with Section 1506(e)) on the Trading Day next succeeding the Expiration Date, such increase to become effective immediately prior to the opening of business on the day following the Expiration Date. If 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 Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon the number of shares actually purchased. If the application of this Section 1506(d)(2) to any tender offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this Section 1506(d)(2). (3) If a tender offer made by a Person (other than the Company or any of its Subsidiaries) for all or any portion of the Common Stock shall expire and such tender or exchange offer shall involve the payment by a Person (other than the Company or any of its Subsidiaries) of consideration per share of Common Stock having a 32 36 fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive) at the applicable Expiration Time that exceeds the current market price of the Common Stock on the Trading Day next succeeding the applicable Expiration Time in which, as of the closing or expiration date of the tender offer, the Company's Board of Directors is not recommending rejection of the offer, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the close of business on the Effective Date by a fraction, of which the numerator 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 (excluding any Purchased Shares and any shares held in the treasury of the Company) at the Expiration Time multiplied by the current market price of the Common Stock (as determined in accordance with Section 1506(e)) on the Trading Day next succeeding the Expiration Date, and of which the denominator shall be the product of the number of shares of Common Stock outstanding (including tendered shares, but excluding shares held in the treasury of the Company) at the Expiration Time multiplied by the current market price of the Common Stock (as determined in accordance with Section 1506(e)) on the Trading Day next succeeding the Expiration Time, such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. Notwithstanding the foregoing, (a) the adjustment of the Conversion Rate contemplated by this Section 1506(d)(3) will only be made if the tender offer is made for an amount which increases that Person's beneficial ownership of Common Stock to more than 25% of the total shares of Common Stock outstanding, and (b) the adjustment to the Conversion Rate contemplated by this Section 1506(d)(3) will not be made if as of the close of the tender offer, the offering documents with respect to such tender offer disclose a plan or an intention to cause the Company to engage in a consolidation or merger of the Company or a sale of all or substantially all of the assets of the Company. (4) For purposes of this Section 1506(d), the term "tender offer" shall mean and include both tender offers and exchange offers (other than an odd-lot offer), all references to "purchases" of shares in tender 33 37 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. (e) For the purpose of any computation under subsections (b), (c) and (d) of this Section 1506, the current market price per share of Common Stock on any date shall be deemed to be the average of the daily closing prices for the 10 consecutive Trading Days ending on the Trading Day preceding (i) the Determination Date or the Expiration Date, as the case may be, with respect to distributions or tender offers under Section 1506(d) or (ii) the record date with respect to distributions, issuances or other events requiring such computation under Section 1506(b) or Section 1506(c); provided, however, if more than one event occurs that would require an adjustment pursuant to Sections 1506(a) through (d), inclusive, the Board of Directors of the Company may make such adjustments to the closing prices during such 10 Trading Day period as it deems appropriate to effectuate the intent of this Section 1506, in which case any such determination by the Board of Directors shall be conclusive. The closing price for each day 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, if the Common Stock is not listed or admitted to trading on the NYSE, on the principal national securities exchange on which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on any national securities exchange, the last reported sales price of the Common Stock as quoted on NASDAQ (the term "NASDAQ" shall include, without limitation, the NASDAQ National Market) or, in case no reported sales takes place, the average of the closing bid and asked prices as quoted on NASDAQ or any comparable system or, if the Common Stock is not quoted on NASDAQ or any comparable 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 the fair value of a share of Common Stock as determined by the Board of Directors (which shall be evidenced by an Officers' Certificate delivered to the Trustee). 34 38 (f) In any case in which this Section 1506 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 1506, 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 1506) issuing to the Holder of any 2020 Debenture 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 Rate 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 Rate 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 Rate shall be readjusted to the Conversion Rate 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 1507 No Adjustment. No adjustment in the Conversion Rate shall be required unless the adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which by reason of this Section 1507 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article FIFTEEN shall be made to the nearest cent or to the nearest 1/1000th 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 or for any issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or carrying the right to purchase any of the foregoing except as provided in this Article FIFTEEN or on account of making an election following a Tax Event pursuant to Section 1801. 35 39 To the extent that the 2020 Debentures 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 1508 Adjustment for Tax Purposes. The Company shall be entitled to make such adjustments in the Conversion Rate, in addition to those required by Section 1506, 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 1509 Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers' Certificate specifying the adjusted Conversion Rate, and briefly stating the facts requiring the adjustment and the manner of computing it. SECTION 1510 Notice of Certain Transactions. If: (1) the Company takes any action which would require an adjustment in the Conversion Rate, (2) the Company takes any action that requires a supplemental indenture pursuant to Section 1511, 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 15 days (seven days in the case of an adjustment to the Conversion Rate pursuant to Section 1513) 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 1510. 36 40 SECTION 1511 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 2020 Debentures (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); (b) any consolidation or merger in which the Company is a party consolidating with another entity or merging with or into another entity 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 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) in, outstanding shares of Common Stock; or (c) any sale or conveyance of all or substantially all of the property and assets of the Company 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, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each 2020 Debenture then outstanding shall have the right to convert such 2020 Debenture into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such 2020 Debenture immediately prior to such reclassification, change, consolidation, merger, sale or conveyance; provided, however, that if the kind or amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, sale or conveyance is not the same for each share of Common Stock of the Company held immediately prior to such reclassification, change, consolidation, merger, sale or conveyance in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this Section 1511 the kind and amount of securities, cash and other property receivable upon such reclassification, change, consolidation, merger, sale or conveyance by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares. Such supplemental indenture shall provide for adjustments of the Conversion Rate which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Rate provided for in this Article FIFTEEN. If, in the case of any such consolidation, 37 41 merger, 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, 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 2020 Debentures as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 1511 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales or conveyances. If the Company shall execute a supplemental indenture pursuant to this Section 1511, 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 2020 Debentures upon the conversion of their 2020 Debentures after any such reclassification, change, 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 1512 Trustee's Disclaimer. The Trustee shall have no duty to determine when an adjustment under this Article FIFTEEN 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 1509. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of 2020 Debentures, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article FIFTEEN. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 1511, but may accept as conclusive evidence of the correctness thereof, and shall be fully 38 42 protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 1511. SECTION 1513 Voluntary Increase. The Company from time to time may increase the Conversion Rate, in addition to those which may be required pursuant to other provisions of this Article FIFTEEN, by any amount and for any period of time as the Company's Board of Directors determines to be in the best interests of the Company, provided that (a) the period of such increase is at least 20 days or such longer period as may be required by law and (b) the increase is irrevocable during the period. Subsequent to any increase in the Conversion Rate made pursuant to this Section 1513, the Company may lower the Conversion Rate to any Conversion Rate that is not lower than the Conversion Rate that would have been applicable had the increase pursuant to this Section 1513 not been made. A determination by the Company's Board of Directors to increase or decrease the Conversion Rate in accordance with this Section 1513 shall be conclusive. If the Company increases or decreases the Conversion Rate, the Company will give at least seven days' advance notice of same, such notice to be given in accordance with Section 1510. ARTICLE SIXTEEN REPURCHASE OF SECURITIES AT OPTION OF THE HOLDER SECTION 1601 General. The Company may be required to repurchase 2020 Debentures in accordance with their terms and in accordance with this Article Sixteen. 2020 Debentures shall be purchased by the Company under the paragraph "Repurchase by the Company at the Option of the Holder" of the 2020 Debentures on June 30, 2005, June 30, 2010 and June 30, 2015 (each, a "Repurchase Date"), at the repurchase price specified therein (each, a "Repurchase Price"), at the option of the Holder thereof, upon: (1) delivery to the Paying Agent by the Holder of a written notice of purchase (a "Repurchase Notice") at any time from the opening of 39 43 business on the date that is 20 Business Days prior to a Repurchase Date until the close of business on such Repurchase Date stating: (A) the certificate number of the 2020 Debenture which the Holder will deliver to be repurchased or, if any of the 2020 Debentures is in the form of a Global Security, then a beneficial owner of a 2020 Debenture shall comply with the procedures of the Depositary applicable to the repurchase of a Global Security, (B) the portion of the Principal Amount of the 2020 Debenture which the Holder will deliver to be repurchased, which portion must be $1,000 or an integral multiple thereof, (C) that such 2020 Debenture shall be purchased as of the Repurchase Date pursuant to the terms and conditions specified under the paragraph "Repurchase by the Company at the Option of the Holder" of the 2020 Debentures and in this Indenture, and (D) if the Company elects, pursuant to Section 1602 hereof, to pay the Repurchase Price to be paid as of such Repurchase Date, in whole or in part, in Common Stock but such portion of the Repurchase Price shall ultimately be payable to such Holder entirely in cash because any of the conditions to payment of the Repurchase Price in Common Stock is not satisfied prior to the close of business on such Repurchase Date, as set forth in Section 1603 hereof, whether such Holder elects (i) to withdraw such Repurchase Notice as to some or all of the 2020 Debentures to which such Repurchase Notice relates (stating the Principal Amount at Maturity and certificate numbers of the 2020 Debentures as to which such withdrawal shall relate or if certificated 2020 Debentures have not been issued, a beneficial owner of a 2020 Debenture shall comply with the procedures of the Depositary applicable to the withdrawal of a Repurchase Notice), or (ii) to receive cash in respect of the entire Repurchase Price for all 2020 Debentures (or portions thereof) to which such Repurchase Price relates; and (2) delivery of such 2020 Debenture to the Paying Agent prior to, on or after the Repurchase Date (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the Holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Article SIXTEEN only if the 2020 Debenture so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice. 40 44 If a Holder, in such Holder's Repurchase Notice and in any written notice of withdrawal delivered by such Holder pursuant to the terms of Section 1609 hereof, fails to indicate such Holder's choice with respect to the election set forth in Section 1601(1)(D), such Holder shall be deemed to have elected to receive cash in respect of the Repurchase Price for all 2020 Debentures subject to the Repurchase Notice in the circumstances set forth in such Section 1601(1)(D). The Company shall purchase from the Holder thereof, pursuant to this Article SIXTEEN, a portion of a 2020 Debenture if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a 2020 Debenture also apply to the purchase of such portion of such 2020 Debenture. Any purchase by the Company contemplated pursuant to the provisions of this Article SIXTEEN, shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Repurchase Date and the time of delivery of the 2020 Debenture. Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 1601 shall have the right to withdraw such Repurchase Notice at any time prior to the close of business on the Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 1609. The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. SECTION 1602 The Company's Right to Elect Manner of Payment of Repurchase Price. (a) The Repurchase Price of 2020 Debentures in respect of which a Repurchase Notice pursuant to Section 1601 has been given will be paid by the Company, at the election of the Company, with cash or Common Stock or in any combination of cash and Common Stock, subject to the conditions set forth in Sections 1602 and 1603 hereof. The Company shall designate, in the Company Notice delivered pursuant to Section 1605 hereof, whether the Company will purchase the 2020 Debentures for cash or Common Stock, or, if a combination 41 45 thereof, the percentages of the Repurchase Price of 2020 Debentures in respect of which it will pay in cash and Common Stock; provided, however, that the Company will pay cash for fractional interests in Common Stock. For purposes of determining the existence of potential fractional interests, all 2020 Debentures subject to purchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder whose 2020 Debentures are purchased pursuant to this Article SIXTEEN shall receive the same percentage of cash or Common Stock in payment of the Repurchase Price for such 2020 Debentures, except (i) as provided in Section 1604 with regard to the payment of cash in lieu of fractional Common Stock and (ii) if the Company is unable to purchase the 2020 Debentures of a Holder or Holders for Common Stock because any necessary qualifications or registrations of the Common Stock under applicable state securities laws cannot be obtained, the Company may purchase the 2020 Debentures of such Holder or Holders for cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given its Company Notice to Holders except pursuant to this Section 1602 or pursuant to Section 1604 in the event of a failure to satisfy, prior to the close of business on the Repurchase Date, any condition to the payment of the Repurchase Price, in whole or in part, in Common Stock. At least three Business Days before the Company Notice Date, the Company shall deliver an Officers' Certificate to the Trustee specifying: (i) the manner of payment selected by the Company, (ii) the information required by Section 1605, (iii) if the Company elects to pay the Repurchase Price, or a specified percentage thereof, in Common Stock, that the conditions to such manner of payment set forth in Section 1604 have been or will be complied with, and (iv) whether the Company desires the Trustee to give the Company Notice required by Section 1605. 42 46 SECTION 1603 Purchase with Cash. On each Repurchase Date, at the option of the Company, the Repurchase Price of 2020 Debentures in respect of which a Repurchase Notice pursuant to Section 1601 has been given, or a specified percentage thereof, may be paid by the Company with cash equal to the aggregate Repurchase Price of such 2020 Debentures. If the Company elects to purchase 2020 Debentures with cash, the Company Notice, as provided in Section 1605, shall be sent to Holders (and to beneficial owners as required by applicable law) not less than 20 Business Days prior to such Purchase Date (the "Company Notice Date"). SECTION 1604 Payment by Issuance of Common Stock. On each Repurchase Date, at the option of the Company, the Repurchase Price of 2020 Debentures in respect of which a Repurchase Notice pursuant to Section 1601 has been given, or a specified percentage thereof, may be paid by the Company by the issuance of a number of shares of Common Stock equal to the quotient obtained by dividing (i) the amount of cash to which the Holders would have been entitled had the Company elected to pay all or such specified percentage, as the case may be, of the Repurchase Price of such 2020 Debentures in cash by (ii) the Market Price of a share of Common Stock, subject to the next succeeding paragraph. The Company will not issue a fractional share of Common Stock in payment of the Repurchase Price. Instead the Company will pay cash for the current market value of the fractional share. The current market value of a fraction of a share of Common Stock shall be determined by multiplying the Market Price by such fraction and rounding the product to the nearest whole cent with one half cent being rounded upwards. It is understood that if a Holder elects to have more than one 2020 Debenture repurchased, the number of shares of Common Stock shall be based on the aggregate amount of 2020 Debentures to be repurchased. If the Company elects to purchase the 2020 Debentures by the issuance of Common Stock, the Company Notice, as provided in Section 1605, shall be sent to the Holders (and to beneficial owners as required by applicable law) not later than the Company Notice Date. 43 47 The Company's right to exercise its election to purchase the 2020 Debentures pursuant to this Article SIXTEEN through the issuance of Common Stock shall be conditioned upon: (i) the Company's not having given its Company Notice of an election to pay entirely in cash and its giving of timely Company Notice of election to purchase all or a specified percentage of the 2020 Debentures with Common Stock as provided herein; (ii) the registration of the Common Stock to be issued in respect of the payment of the Repurchase Price under the Securities Act or the Exchange Act, in each case, if required for the initial issuance thereof; (iii) any necessary qualification or registration under applicable state securities laws or the availability of an exemption from such qualification and registration; and (iv) the receipt by the Trustee of an Officers' Certificate and an Opinion of Counsel each stating that (A) the terms of the issuance of the Common Stock are in conformity with this Indenture and (B) the shares of Common Stock to be issued by the Company in payment of the Repurchase Price in respect of 2020 Debentures have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Repurchase Price in respect of the 2020 Debentures, will be validly issued, fully paid and nonassessable and, to the best of such counsel's knowledge, free from preemptive rights, and, in the case of such Officer's Certificate, stating that conditions (i), (ii) and (iii) above and the condition set forth in the second succeeding sentence have been satisfied and, in the case of such Opinion of Counsel, stating that conditions (ii) and (iii) above have been satisfied. Such Officers' Certificate shall also set forth the number of shares of Common Stock to be issued for each $1,000 Principal Amount of 2020 Debentures and the Sale Price of a share of Common Stock on each trading day during the period commencing on the first trading day of the period during which the Market Price is calculated and ending three Business Days prior to the applicable Repurchase Date. The Company may pay the Repurchase Price (or any portion thereof) in Common Stock only if the Common Stock is then listed for trading on a U.S. national securities exchange or quoted on an interdealer quotation system of any registered United States national securities 44 48 association. If the foregoing conditions are not satisfied with respect to a Holder or Holders prior to the close of business on the Repurchase Date and the Company has elected to repurchase the 2020 Debentures pursuant to this Article Sixteen through the issuance of Common Stock, the Company shall pay, without further notice, the entire Repurchase Price of the 2020 Debentures of such Holder or Holders in cash. The "Market Price" means the average of the Sale Prices of the Common Stock for the five Trading Day period ending on (if the third Business Day prior to the applicable Repurchase Date is a Trading Day, or if not, then on the last Trading Day prior to) the third Business Day prior to the applicable Repurchase Date appropriately adjusted to take into account the occurrence, during the period commencing on the first of such Trading Days during such five Trading Day period and ending on such Repurchase Date, of any event described in Section 1506; subject, however, to the conditions set forth in Sections 1506(f) and 1507. The "Sale Price" of the Common Stock on any date means the closing per share sale price (or, if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and average ask prices) on such date as reported in the composite transactions for the principal United States securities exchange on which the Common Stock is traded or, if the Common Stock is not listed on a United States national or regional securities exchange, as reported by the National Association of Securities Dealers Automated Quotation System or its successors. SECTION 1605 Notice of Election. The Company's notice of election to repurchase with cash or Common Stock or any combination thereof shall be sent to the Holders in the manner provided in Section 106 of the Indenture at the time specified in Section 1603 or 1604, as applicable (the "Company Notice"). Such Company Notice shall state the manner of payment elected and shall contain the following information: If the Company has elected to pay the Repurchase Price (or a specified percentage thereof) with Common Stock, the Company Notice shall: 45 49 (1) state that each Holder will receive Common Stock with a Market Price equal to such specified percentage of the Repurchase Price of the 2020 Debentures held by such Holder (except any cash amount to be paid in lieu of fractional shares); (2) set forth the method of calculating the Market Price of the Common Stock; and (3) state that, because the Market Price of Common Stock will be determined prior to the Repurchase Date, Holders will bear the market risk with respect to the value of the Common Stock to be received from the date such Market Price is determined to the Repurchase Date. In any case, each Company Notice shall include a form of Repurchase Notice to be completed by a Holder and shall state: (A) the Repurchase Price and the Conversion Rate; (B) the name and address of the Paying Agent and the Conversion Agent; (C) that 2020 Debentures as to which a Repurchase Notice has been given may be converted pursuant to Article FIFTEEN hereof only if the applicable Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; (D) that 2020 Debentures must be surrendered to the Paying Agent to collect payment; (E) that the Repurchase Price for any 2020 Debenture as to which a Repurchase Notice has been given and not withdrawn will be paid promptly following the later of the Repurchase Date and the time of surrender of such 2020 Debenture as described in clause (D) above; (F) the procedures the Holder must follow to exercise repurchase rights under this Article SIXTEEN and a brief description of those rights; (G) briefly, the conversion rights of the 2020 Debentures; and 46 50 (H) the procedures for withdrawing a Repurchase Notice (including, without limitation, for a conditional withdrawal pursuant to the terms of Section 1601 or 1609). At the Company's written request, the Trustee shall give such Company Notice in the Company's name and at the Company's expense; provided, however, that, in all cases, the text of such Company Notice shall be prepared by the Company. Upon determination of the actual number of shares of Common Stock to be issued for each $1,000 Principal Amount of 2020 Debentures, the Company will notify the appropriate securities exchange or registered national securities association and will publish such determination at the Company's web site on the world wide web or through such other public medium as the Company may use at that time. SECTION 1606 Covenants of the Company. All Common Stock delivered upon purchase of the 2020 Debentures shall be newly issued shares or treasury 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 shall use its reasonable efforts to list for trading or cause to have quoted any Common Stock to be issued to purchase 2020 Debentures on the principal national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed for trading or quoted. SECTION 1607 Procedure upon Repurchase. The Company shall deposit cash (in respect of a cash purchase under Section 1603 or for fractional shares of Common Stock, as applicable) or Common Stock, or a combination thereof, as applicable, at the time and in the manner as provided in Section 1610, sufficient to pay the aggregate Repurchase Price of all 2020 Debentures to be purchased on the applicable Repurchase Date pursuant to this Article SIXTEEN. As soon as practicable after the Repurchase Date, the Company shall deliver to each Holder entitled to receive Common Stock through the Paying Agent, a certificate for the number of whole shares of Common Stock issuable in payment of the Repurchase Price and cash 47 51 in lieu of any fractional shares of Common Stock. The Person in whose name the certificate for Common Stock is registered shall be treated as a holder of record of Common Stock on the Business Day following the Repurchase Date. Subject to Section 1604, no payment or adjustment will be made for dividends on the Common Stock the record date for which occurred on or prior to the Repurchase Date. SECTION 1608 Taxes. If a Holder of a 2020 Debenture is paid in Common Stock, the Company shall pay any documentary, stamp or similar issue or transfer tax due on such issue of Common Stock. However, the Holder shall pay any such tax which is due because the Holder requests the Common Stock to be issued in a name other than the Holder's name. The Paying Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder's name until the Paying Agent receives a sum sufficient to pay any tax which will be due because the shares of Common Stock are to be issued in a name other than the Holder's name. SECTION 1609 Effect of Repurchase Notice. Upon receipt by the Paying Agent of the Repurchase Notice, the Holder of the 2020 Debenture in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Repurchase Price with respect to such 2020 Debenture. Such Repurchase Price shall be paid to such Holder, subject to receipt of funds and/or Common Stock by the Paying Agent, promptly following the later of (x) the Repurchase Date with respect to such 2020 Debenture (provided the conditions in Section 1601 have been satisfied) and (y) the time of delivery of such 2020 Debenture to the Paying Agent by the Holder thereof in the manner required by Section 1601. 2020 Debentures in respect of which a Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article FIFTEEN hereof on or after the date of the delivery of such Repurchase Notice unless such Repurchase Notice has first been validly withdrawn as specified in the following two paragraphs. A Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in 48 52 accordance with the Repurchase Notice at any time prior to the close of business on the applicable Repurchase Date specifying: (1) the certificate number of the 2020 Debenture in respect of which such notice of withdrawal is being submitted or, if any of the 2020 Debentures is in the form of a Global Security, then a beneficial owner of a 2020 Debenture shall comply with the procedures of the Depositary applicable to the withdrawal of a Repurchase Notice; (2) the Principal Amount of the 2020 Debenture with respect to which such notice of withdrawal is being submitted; and (3) the Principal Amount, if any, of such 2020 Debenture which remains subject to the original Repurchase Notice and which has been or will be delivered for purchase by the Company. A written notice of withdrawal of a Repurchase Notice may be in the form set forth in the preceding paragraph or may be in the form of (i) a conditional withdrawal contained in a Repurchase Notice pursuant to the terms of Section 1601(1)(D) or (ii) a conditional withdrawal containing the information set forth in Section 1601(1)(D) and the preceding paragraph and contained in a written notice of withdrawal delivered to the Paying Agent as set forth in the preceding paragraph. There shall be no purchase of any 2020 Debentures pursuant to this Article SIXTEEN (other than through the issuance of Common Stock in payment of the Repurchase Price, including cash in lieu of fractional shares) if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such 2020 Debentures, of the required Repurchase Notice) and is continuing an Event of Default (other than a default in the payment of the Repurchase Price with respect to such 2020 Debentures). The Paying Agent will promptly return to the respective Holders thereof any 2020 Debentures (x) with respect to which a Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Repurchase Price with respect to such 2020 Debentures) in which case, upon such return, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 49 53 SECTION 1610 Deposit of Repurchase Price. Prior to 11:00 a.m. (New York City time) on the Business Day following the Repurchase Date, the Company shall deposit with the Trustee or with the Paying Agent an amount of money (in immediately available funds if deposited on such Business Day) and/or Common Stock, if permitted hereunder, sufficient to pay in accordance with the Company Notice the aggregate Repurchase Price of all of the 2020 Debentures or portions thereof which are to be purchased as of the Repurchase Date. SECTION 1611 Securities Repurchased in Part. Any 2020 Debenture which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company or the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such 2020 Debenture, without service charge, a new 2020 Debenture or 2020 Debentures, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to, and in exchange for, the portion of the Principal Amount of the 2020 Debenture so surrendered which is not purchased. SECTION 1612 Comply with Securities Laws Upon Purchase of Securities. In connection with any offer to purchase or purchase of 2020 Debentures under this Article SIXTEEN (provided that such offer or purchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply with Rule 13e-4 under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under this Article SIXTEEN to be exercised in the time and in the manner specified in this Article SIXTEEN. 50 54 SECTION 1613 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash or Common Stock that remain unclaimed for two years, subject to applicable unclaimed property law, together with interest or dividends, if any, thereon held by them for the payment of the Repurchase Price; provided, however, that to the extent that the aggregate amount of cash or Common Stock deposited by the Company pursuant to Section 1610 exceeds the aggregate Repurchase Price of the 2020 Debentures or portions thereof which the Company is obligated to purchase as of the Repurchase Date, then promptly after the Business Day following the Repurchase Date the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon. After that, Holders entitled to money must look to the Company for payment as general creditors, unless an applicable abandoned property law designates another Person. SECTION 1614 Conversion Arrangement on Repurchase. Any Securities required to be repurchased under this Article SIXTEEN, unless surrendered for conversion before the close of business on the Repurchase Date, may be deemed to be purchased from the Holders of such Securities for an amount in cash not less than the Repurchase Price, 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 Trustee in trust for such Holders. 51 55 ARTICLE SEVENTEEN PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON FUNDAMENTAL CHANGE SECTION 1701 Right to Require Repurchase. (a) If at any time that 2020 Debentures remain outstanding there shall occur a Fundamental Change (as defined below), 2020 Debentures shall be purchased by the Company at the option of the Holders thereof as of the date that is 35 Business Days after the occurrence of the Fundamental Change (the "Fundamental Change Purchase Date") at a purchase price equal to the Issue Price plus accrued Original Issue Discount through the Fundamental Change Purchase Date (or, if the option under Section 1801 has been exercised, the Restated Principal Amount plus accrued and unpaid interest from the Option Exercise Date to the Fundamental Change Purchase Date) (the "Fundamental Change Purchase Price"), subject to satisfaction by or on behalf of any Holder of the requirements set forth in Section 1701(c). A "Fundamental Change" shall be deemed to have occurred upon the occurrence of any transaction or event in connection with which all or substantially all Common Stock (excluding shares of Common Stock held by any stockholders exercising applicable dissenters' rights) shall be exchanged for, converted into, acquired for or constitute solely the right to receive (whether by means of an exchange offer, liquidation, tender offer, consolidation, merger, combination, reclassification, recapitalization or otherwise) consideration which is not all or substantially all shares of common stock listed (or, upon consummation of or immediately following such transaction or event, which will be listed) on a United States national securities exchange or approved for quotation on The NASDAQ National Market or any similar United States system of automated dissemination of quotations of securities prices. For purposes of making the determination to be made pursuant to the preceding sentence of whether or not the consideration in any such transactions consists of all or substantially all shares of common stock, cash paid or to be paid in respect of fractional shares or applicable dissenter's rights shall be disregarded as part of the consideration. (b) Within 15 Business Days after the occurrence of a Fundamental Change, the Company shall mail a written notice of the Fundamental Change to the Trustee and to each Holder. The notice shall include the form of a Fundamental Change Purchase Notice to be completed by the Holder and shall state: (1) the date of such Fundamental Change and, briefly, the events causing such Fundamental Change; (2) the date by which the Fundamental Change Purchase Notice pursuant to this Section 1701 must be given; (3) the Fundamental Change Purchase Date; 52 56 (4) the Fundamental Change Purchase Price; (5) briefly, the conversion rights of the 2020 Debentures; (6) the name and address of each Paying Agent and Conversion Agent; (7) the Conversion Rate and any adjustments thereto; (8) that 2020 Debentures as to which a Fundamental Change Purchase Notice has been given may be converted into Common Stock pursuant to Article FIFTEEN only to the extent that any Fundamental Change Purchase Notice previously delivered by such Holder 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 1701; (10) the procedures for withdrawing a Fundamental Change Purchase Notice, including a form of notice of withdrawal; and (11) that the Holder must satisfy the requirements set forth in the 2020 Debentures in order to convert the Securities. If any of the 2020 Debentures 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 Section 1701 upon delivery of a written notice (which shall be in substantially the form included as an attachment to the 2020 Debentures 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 "Fundamental Change Purchase Notice") to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Fundamental Change Purchase Date. The delivery of such 2020 Debenture 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 Fundamental Change Purchase Price therefor. 53 57 The Company shall purchase from the Holder thereof, pursuant to this Section 1701, a portion of a 2020 Debenture if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a 2020 Debenture pursuant to Sections 1701 through 1706 also apply to the purchase of such portion of such 2020 Debenture. Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 1701(c) shall have the right to withdraw such Fundamental Change Purchase Notice in whole or as to a portion thereof that is a Principal Amount of $1,000 or an integral multiple thereof at any time prior to the close of business on the Business Day next preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 1702. A Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written withdrawal thereof. Anything herein to the contrary notwithstanding, in the case of Global Securities, any Fundamental Change Purchase Notice may be delivered or withdrawn and such 2020 Debentures may be surrendered or delivered for purchase in accordance with the Applicable Procedures. SECTION 1702 Effect of Fundamental Change Purchase Notice. Upon receipt by any Paying Agent of the Fundamental Change Purchase Notice specified in Section 1701(c), the Holder of the 2020 Debenture in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Fundamental Change Purchase Price with respect to such 2020 Debenture. Such Fundamental Change Purchase Price shall be paid to such Holder promptly following the later of (a) the Fundamental Change Purchase Date with respect to such 2020 Debenture (provided the conditions in Section 1701(c) have been satisfied) and (b) the time of delivery of such 2020 Debenture to a Paying Agent by the Holder thereof in the manner required by Section 1701(c). 2020 Debentures in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted into Common Stock on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has first been validly withdrawn. A Fundamental Change 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 54 58 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 Fundamental Change Purchase Date, specifying 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 of withdrawal is being submitted. SECTION 1703 Deposit of Fundamental Change Purchase Price. On or before 11:00 a.m. New York City time on the Fundamental Change 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 Fundamental Change Purchase Price of all the 2020 Debentures or portions thereof that are to be purchased as of such Fundamental Change Purchase Date. The manner in which the deposit required by this Section 1703 is made by the Company shall be at the option of the Company, provided, however, that such deposit shall be made in a manner such that the Trustee or a Paying Agent shall have immediately available funds on the Fundamental Change Purchase Date. If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Fundamental Change Purchase Price of any 2020 Debenture for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Fundamental Change Purchase Date, such 2020 Debenture will cease to be outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Fundamental Change Purchase Price as aforesaid). The Company shall publicly announce the Principal Amount of 2020 Debentures purchased as a result of such Fundamental Change on or as soon as practicable after the Fundamental Change Purchase Date. SECTION 1704 Securities Purchased In Part. Any 2020 Debenture that is to be purchased only in part shall be surrendered at the office of a Paying Agent and promptly after the Fundamental Change Purchase Date the Company shall execute and 55 59 the Trustee shall authenticate and deliver to the Holder of such 2020 Debenture, without service charge, a new 2020 Debenture or 2020 Debentures, 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 2020 Debenture so surrendered that is not purchased. SECTION 1705 Compliance With Securities Laws Upon Purchase of Securities. In connection with any offer to purchase or purchase of 2020 Debentures under Section 1701, the Company shall (a) comply with Rule 13e-4 (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, all so as to permit the rights of the Holders and obligations of the Company under Sections 1701 through 1706 to be exercised in the time and in the manner specified therein. SECTION 1706 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 1703 exceeds the aggregate Fundamental Change Purchase Price together with interest, if any, thereon of the 2020 Debentures or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess to the Company. 56 60 ARTICLE EIGHTEEN SPECIAL TAX EVENT CONVERSION SECTION 1801 Optional Conversion to Interest-Bearing Securities Upon Tax Event. From and after the date (the "Option Exercise Date") that is the later of (i) the date (the "Tax Event Date") of the occurrence of a Tax Event and (ii) the date the Company exercises such option, at the option of the Company with respect to its 2020 Debentures only, interest in lieu of Original Issue Discount to accrue from and after the Option Exercise Date shall accrue at the rate of 3.0% per annum on a restated principal amount per $1,000 original Principal Amount (the "Restated Principal Amount") equal to the Issue Price plus Original Issue Discount accrued to the Option Exercise Date and shall be payable semiannually on each Interest Payment Date to holders of record at the close of business on each Regular Record Date immediately preceding such Interest Payment Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months and will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from the Option Exercise Date. Within 15 days after the occurrence of a Tax Event, the Company shall mail a written notice of such Tax Event by first-class mail to the Trustee and within 15 days after its exercise of such option the Company shall mail a written notice of the Option Exercise Date by first-class mail to the Trustee and Holders of the 2020 Debentures. From and after the Option Exercise Date, (i) the Company shall be obligated to pay at Stated Maturity, in lieu of the Principal Amount of a Security, the Restated Principal Amount thereof and (ii) "Issue Price and accrued Original Issue Discount," "Issue Price plus Original Issue Discount" or similar words, as used herein, shall mean Restated Principal Amount plus accrued and unpaid interest with respect to any 2020 Debenture. 2020 Debentures authenticated and delivered after the Option Exercise Date may, and shall if required by the Trustee, bear a notation in a form approved by the Trustee as to the conversion of the 2020 Debentures to interest-bearing 2020 Debentures. 57 61 ARTICLE THREE MODIFICATIONS OF INDENTURE SECTION 301 Modifications to Indenture.

THE BANK OF NEW YORK, as Trustee --------------------------------------- Authorized Signatory Date of Authentication: -------------------- A-6 72 [FORM OF REVERSE SIDE OF SECURITY] WEATHERFORD INTERNATIONAL, INC. ZERO COUPON CONVERTIBLE SENIOR DEBENTURE DUE JUNE 30, 2020 This Security is one of a duly authorized issue of senior securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of May 17, 1996, as supplemented by the First Supplemental Indenture thereto, dated as of May 27, 1998, and the Second Supplemental Indenture thereto, dated as of June 30, 2000 (as so amended, herein called the "Indenture"), between the Company and The Bank of New York, 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 and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount at maturity to $910,000,000; provided, however, that if the Company sells any Securities pursuant to the Option granted to the Initial Purchaser pursuant to Section 2 of the Purchase Agreement, the Securities shall be limited in aggregate principal amount at maturity to up to $1,050,000,000. INTEREST This Security shall not bear interest, except as specified in this paragraph or as described under "Tax Event." If the Principal Amount hereof or any portion of such Principal Amount is not paid when due (whether upon acceleration pursuant to Section 502 of the Indenture, upon the date set for payment of the Redemption Price as described under "Optional Redemption", upon the date set for payment of the Fundamental Change Purchase Price pursuant to "Purchase of Securities at Option of Holder Upon a Fundamental Change", upon the date set for payment of the Repurchase Price under "Repurchase by the Company at the Option of the Holder" or upon the Stated Maturity of this Security) or if interest due hereon, 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 of 3.0% per annum, compounded semi-annually, 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. The accrual of such interest on overdue amounts shall be in lieu of, and not in addition to, the continued accrual of Original Issue Discount. Original Issue Discount (the difference between the Issue Price and the Principal Amount of the Security), in the period during which a Security remains outstanding, shall accrue at 3.0% per annum, on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months, from the Issue Date of this Security. A-7 73 OPTIONAL REDEMPTION No sinking fund is provided for the Securities. The Securities are redeemable as a whole, or from time to time in part, at any time at the option of the Company at the Redemption Price set forth below, on or after June 30, 2005. The table below shows Redemption Prices of a Security per $1,000 Principal Amount on the dates shown below and at Stated Maturity, which prices reflect accrued Original Issue Discount calculated through each such date.

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 will be deemed to be from the portion selected for redemption. A-8 74 NOTICE OF REDEMPTION Notice of redemption will be mailed by first-class mail at least 30 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 Principal Amount 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, Original Issue Discount (or interest, if the Security is converted to an interest-bearing debenture) ceases to accrue on Securities or portions thereof called for redemption. PURCHASE OF SECURITIES AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE 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 35 Business Days after the occurrence of a Fundamental Change, at a Fundamental Change Purchase Price equal to the Issue Price plus accrued Original Issue Discount through the Fundamental Change Purchase Date. The Holder shall have the right to withdraw any Fundamental Change Purchase Notice (in whole or in a portion thereof that is $1,000 Principal Amount or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business on the Business Day prior to the Fundamental Change Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. If prior to a Fundamental Change Purchase Date this Security has been converted to an interest-bearing debenture following the occurrence of a Tax Event, the Fundamental Change Purchase Price shall be equal to the Restated Principal Amount plus accrued and unpaid interest from the date of conversion to the Fundamental Change Purchase Date. CONVERSION A Holder of a Security may convert the Security into shares of Common Stock at any time until the close of business on the Business Day prior to the Stated Maturity; provided, however, that if the Security is called for redemption, the conversion right will terminate at the close of business on the Business Day immediately preceding the Redemption Date for such Security or such earlier date as the Holder presents such Security for redemption (unless the Company shall default in making the redemption 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). A Security in respect of which a Holder has delivered a Repurchase 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 initial Conversion Rate is 9.9970 shares of Common Stock per $1,000 Principal Amount, subject to adjustment in certain events A-9 75 described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock. If the Company exercises its option pursuant to Section 1801 of the Indenture to have interest in lieu of Original Issue Discount accrue on the Security following a Tax Event, the Holder will be entitled on conversion to receive the same number of shares of Common Stock such Holder would have received if the Company had not exercised such option. If the Company exercises such option, Securities 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 of such Interest Payment Date (except Securities or portions of Securities to be redeemed on a Redemption Date occurring during the period from the close of business on a Regular Record Date and ending on the opening of business on the first Business Day after the next Interest Payment Date, or if this Interest Payment Date is not a Business Day, the second Business Day after the Interest Payment Date) must be accompanied by payment from the Holder of an amount equal to the interest thereon that the registered Holder is to receive from the Company on such Interest Payment Date. Except where Securities surrendered for conversion must be accompanied by payment as described above, no interest on converted Securities will be payable by the Company on any Interest Payment Date subsequent to the date of conversion. 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 (and interest if the Security is converted to an interest-bearing debenture) attributable to the period from the Issue Date (or, in the case of interest, if the Company has exercised the option referred to in "Tax Event", the later of (x) the date of such exercise and (y) the date on which interest was last paid) through the Conversion Date with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through the delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the Security being converted pursuant to the terms hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall be treated as issued, to the extent thereof, first in exchange for Original Issue Discount (and interest, if the Company has exercised its option provided for in "Tax Event") accrued through the Conversion Date, and the balance, if any, of such fair market value of such 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. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the closing price 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 the A-10 76 Conversion Agent, (c) furnish appropriate endorsements and transfer documents (including any certification that may be required under applicable law) if required by the Conversion Agent, and (d) pay any transfer or similar tax, if required. REPURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, the Securities held by such Holder on the following Repurchase Dates and at the following Repurchase Prices per $1,000 Principal Amount, upon delivery of a Repurchase 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 Repurchase Date until the close of business on such Repurchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture. REPURCHASE DATE REPURCHASE PRICE --------------- ----------------- June 30, 2005................. $ 639.76 June 30, 2010................. $ 742.47 June 30, 2015................. $ 861.67 The Repurchase Price (equal to the Issue Price plus accrued Original Issue Discount through the Repurchase Date) may be paid, at the option of the Company, in cash or by the issuance of Common Stock (as provided in the Indenture), or in any combination thereof. If prior to a Repurchase Date this Security has been converted to an interest-bearing debenture following the occurrence of a Tax Event, the Repurchase Price will be equal to the Restated Principal Amount plus accrued and unpaid interest from the date of conversion to the Repurchase Date. Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal prior to the close of business on the Repurchase Date in accordance with the provisions of the Indenture. If cash (and/or securities if permitted under the Indenture) sufficient to pay the Repurchase Price of all Securities or portions thereof to be purchased as of the Repurchase Date, is deposited with the Paying Agent on the Business Day following the Repurchase Date, such Securities shall cease to be outstanding, Original Issue Discount (or interest, if this Security has been converted to an interest-bearing debenture following the occurrence of a Tax Event) shall cease to accrue on such Securities (or portions thereof) immediately after such Repurchase Date, and the Holder thereof shall have no other rights as such (other than the right to receive the Repurchase Price upon surrender of such Security). A-11 77 TAX EVENT From and after the date (the "Option Exercise Date") that is the later of (i) the date (the "Tax Event Date") of the occurrence of a Tax Event and (ii) the date the Company exercises such option, at the option of the Company, interest in lieu of future Original Issue Discount shall accrue at the rate of 3.0% per annum on a Principal Amount per Security (the "Restated Principal Amount") equal to the Issue Price plus Original Issue Discount accrued through the Option Exercise Date and shall be payable semiannually on June 30 and December 31 of each year (each an "Interest Payment Date") to holders of record at the close of business on June 15 or December 15 (each a "Regular Record Date") immediately preceding such Interest Payment Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months and will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Option Exercise Date. Interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security is registered at the close of business on the Regular Record Date. Except as otherwise specified with respect to the Securities, any Defaulted Interest on any Security shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 307 of the Indenture. CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION Any Securities called for redemption, unless surrendered for conversion before the close of business on the Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, 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. TRANSFER As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration or transfer at the office or agency in a place of payment for Securities of this series, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of any authorized denominations and for the same aggregate principal amount, executed by the Company and authenticated and delivered by the Trustee, will be issued to the designated transferee or transferees. A-12 78 The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations set forth therein and on the face of this Security, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee or any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
