WITNESSETH WHEREAS, the Company has heretofore executed and delivered to the Trustee an Indenture, dated as of February 4, 1997 (the "Indenture"), providing for the issuance from time to time of its debentures, notes, bonds or other evidences of indebtedness (hereinafter called "Securities") in one or more fully registered series; WHEREAS, Section 901(5) of the Indenture provides that the Company and the Trustee may from time to time enter into one or more indentures supplemental thereto to establish the form or terms of Securities of a new series; WHEREAS, Sections 901(2) and 901(7) of the Indenture permit the execution of supplemental indentures without the consent of any Holders to add to the covenants of the Company for the benefit of, and to add any additional Events of Default with respect to, all or any series of Securities; WHEREAS, Section 301 of the Indenture provides that the Company may enter into supplemental indentures to establish the terms and provisions of a series of Securities issued pursuant to the Indenture; WHEREAS, the Company desires to issue 1 1/2% Convertible Senior Debentures due 2031 (the "2031 Debentures"), a new series of Security, the issuance of which was authorized by resolution of the Executive Committee of the Board of Directors of the Company, dated April 6, 2001; WHEREAS, the Company, pursuant to the foregoing authority, proposes in and by this Third Supplemental Indenture to supplement and amend in certain respects the Indenture insofar as it will apply only to the 2031 Debentures (and not to any other series); and WHEREAS, all things necessary have been done to make the 2031 Debentures, when executed by the Company and authenticated and delivered hereunder and duly issued by the Company, the valid obligations of the Company, and to make this Third Supplemental Indenture a valid agreement of the Company, in accordance with their and its terms. 5 NOW THEREFORE: In consideration of the premises provided for herein, the Company and the Trustee mutually covenant and agree for the equal and proportionate benefit of all Holders of the 2031 Debentures as follows: ARTICLE ONE THE 2031 DEBENTURES Section 101 Designation of 2031 Debentures; Establishment of Form. There shall be a series of Securities designated "1 1/2% Convertible Senior Debentures due 2031" 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 Third Supplemental Indenture, 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 2031 Debentures, as evidenced by their execution of the 2031 Debentures. (a) Restricted Global Securities. All of the 2031 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 2031 Debentures represented thereby with the Trustee, at its Corporate Trust Office, as Securities Custodian for the depositary, The Depository Trust Company ("DTC") (such depositary, or any successor thereto, being hereinafter referred to as the "Depositary'), and registered in the name of its nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as hereinafter provided. 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 Securities Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures. (b) Institutional Accredited Investor Securities. Except as provided in this Section 101 or Section 102, owners of beneficial interests in Global Securities will not be entitled to receive physical delivery of Certificated Securities. Securities offered and sold within the United States to institutional accredited investors as defined in Rule 501(a)(1), (2), (3) and (7) under the Securities Act ("Institutional Accredited Investors") shall be issued, initially in the form of Certificated Securities, duly executed by the Company and authenticated by the Trustee as hereinafter provided. (c) Global Securities in General. Each Global Security shall represent such of the Outstanding 2031 Debentures as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of Outstanding 2031 Debentures from time to time endorsed thereon and that the aggregate principal amount of Outstanding 2031 Debentures 2 6 represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, purchases or conversions of such 2031 Debentures. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the principal amount of Outstanding 2031 Debentures represented thereby shall be made by the Securities Custodian in accordance with the standing instructions and procedures existing between the Depositary and the Securities Custodian. Neither any members of, or participants in, the Depositary ("Agent Members") nor any other Persons on whose behalf Agent Members may act shall have rights under this Indenture with respect to any Global Security held in the name of the Depositary or any nominee thereof, 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, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices governing the exercise of the rights of a Holder of any 2031 Debenture. (d) Certificated Securities. Certificated Securities shall be issued only under the limited circumstances provided in Sections 101(b), 102(a)(1) and 102(b) hereof. (e) Paying Agent, Conversion Agent and Bid Solicitation Agent. The Company shall maintain an office or agency where 2031 Debentures may be presented for purchase or payment ("Paying Agent") and an office or agency where 2031 Debentures may be presented for conversion ("Conversion Agent"). The Company shall also appoint a bid solicitation agent (the "Bid Solicitation Agent") to act as set forth under the caption "Contingent Interest" in the 2031 Debentures. The Company may have one or more additional paying agents and one or more additional conversion agents. The Company shall enter into an appropriate agency agreement with any Paying Agent, Conversion Agent or Bid Solicitation Agent (other than the Trustee). The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Paying Agent, Conversion Agent or Bid Solicitation Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 607. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent or Conversion Agent. None of the Company or any Subsidiary or any Affiliate of either of them may act as Bid Solicitation Agent. The Company initially appoints the Trustee as Conversion Agent, Paying Agent and Bid Solicitation Agent in connection with the 2031 Debentures. 3 7 Section 102 Transfer and Exchange. (a) Transfer and Exchange of Global Securities. (1) Except as provided in Section 102(b), Certificated Securities shall be issued in exchange for interests in the Global Securities only if (x) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for the Global Securities or if it at any time ceases to be a "clearing agency" registered under the Exchange Act if so required by applicable law or regulation and a successor depositary is not appointed by the Company within 90 days, or (y) an Event of Default has occurred and is continuing. In either case, the Company shall execute, and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver Certificated Securities in an aggregate principal amount equal to the principal amount of such Global Securities in exchange therefor.

Certificated Securities issued in exchange for beneficial interests in Global Securities shall be registered in such names and shall be in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver or cause to be delivered such Certificated Securities to the persons in whose names such Securities are so registered. Such exchange shall be effected in accordance with the Applicable Procedures. Nothing herein shall require the Trustee to communicate directly with beneficial owners, and the Trustee shall in connection with any transfers hereunder be entitled to rely on instructions received through the registered Holder. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities in accordance with the foregoing paragraph and, thereafter, the events or conditions specified in this Section 102(a)(1) which required such exchange shall have ceased to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Certificated Securities for interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring that such notice be given.

Nothing in this Section 102(a)(2) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 102. 4 8 (b) Restrictions on Transfer of a Beneficial Interest in a Global Security for a Certificated Security.

Each Holder and any beneficial holder of a 2031 Debenture by its purchase thereof shall be deemed to be bound by the Company's application of Section 1.1275-4(b) of the Treasury Regulations, including the Company's determination that the rate at which interest will be deemed to accrue for federal income tax purposes will be 6.5%. Each Holder and any beneficial holder of a 2031 Debenture by its purchase thereof shall be deemed to acknowledge that (x) it will recognize ordinary income upon a conversion of 2031 Debentures into Common Stock of the Company, or upon the repurchase of a 2031 Debenture when the Company elects to pay in Common Stock of the Company and the Holder does not withdraw its Repurchase Notice in accordance with Section 1509, equal to the excess, if any, of the value of the Common Stock received on the conversion or repurchase over the sum of the original purchase price of such 2031 Debentures and accrued but unpaid interest and (y) it will recognize ordinary income upon a sale or exchange of 2031 Debentures equal to the excess, if any, of the amount of cash received plus the fair market value of any other property received over the original purchase price of such 2031 Debentures and accrued but unpaid interest. Each Holder and any beneficial holder of a 2031 Debenture by its purchase thereof shall be deemed to acknowledge that any loss resulting from any conversion, redemption, sale or exchange will be treated as ordinary loss to the extent interest from the 2031 Debenture was previously included in income, and thereafter capital loss. The Company acknowledges and agrees, and each Holder and any beneficial holder of a Security by its purchase thereof shall be deemed to acknowledge and agree, that (i) the comparable yield and the schedule of projected payments are not determined for any purpose other than for the determination of interest accruals and adjustments thereof in respect of the 2031 Debentures for United States federal income tax purposes and (ii) the comparable yield and the schedule of projected payments do not constitute a projection or representation regarding the amounts payable on the 2031 Debentures or the value of Common Stock into which the 2031 Debentures are convertible. Section 214 Maintenance of Office or Agency. The first paragraph of Section 1002 of the Indenture is hereby amended, subject to Section 201 hereof and with respect to the 2031 Debentures only, by changing the first sentence thereof to read in its entirety as follows: The Company will maintain in each Place of Payment for the 2031 Debentures an office or agency where the 2031 Debentures may be presented or 27 31 surrendered for payment, where the 2031 Debentures may be surrendered for registration of transfer or exchange, where the 2031 Debentures may be surrendered for conversion and where notices and demands to or upon the Company in respect of the 2031 Debentures and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. Section 215 Redemption. (a) Section 1104 of the Indenture is hereby amended, subject to Section 201 hereof and with respect to the 2031 Debentures only, by inserting the following paragraph: (7) the election of the Company (which, subject to the provisions of Article Fourteen of this Indenture, shall be irrevocable) to deliver shares of Common Stock or to pay cash in lieu of delivery of such shares with respect to any 2031 Debentures that may be exchanged after the mailing of such notice and prior to the Redemption Date. (b) Article Eleven of the Indenture is hereby amended, subject to Section 201 hereof and with respect to the 2031 Debentures only, by inserting the following section in its entirety: SECTION 1109 Conversion Arrangement on Call for Redemption. In connection with 2031 Debentures, the Company may arrange for the purchase and conversion of any 2031 Debentures called for redemption by an agreement with one or more investment bankers or other purchasers to purchase such 2031 Debentures by paying to a Paying Agent (other than the Company or any of its Affiliates) in trust for the Holders, on or before 11:00 A.M. New York City time on the Redemption Date, an amount that, together with any amounts deposited with such Paying Agent by the Company for the redemption of such 2031 Debentures, is not less than the Redemption Price of and any accrued and unpaid contingent interest with respect to, such 2031 Debentures. Notwithstanding anything to the contrary contained in this Article Eleven, the obligation of the Company to pay the Redemption Price of such 2031 Debentures, including accrued contingent interest, if any, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers; provided, however, that nothing in this Section 1109 shall relieve the Company of its obligation to pay the Redemption Price of, and any accrued and unpaid contingent interest with respect to, 2031 Debentures called for redemption. If such an 28 32 agreement is entered into, any 2031 Debentures called for redemption and not surrendered for conversion by the Holders thereof prior to the relevant Redemption Date may, at the option of the Company upon written notice to the Trustee, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article Fourteen) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the Business Day immediately prior to the Redemption Date, subject to payment of the above amount as aforesaid. The Paying Agent shall hold and pay to the Holders whose 2031 Debentures are selected for redemption any such amount paid to it for purchase in the same manner as it would money deposited with it by the Company for the redemption of 2031 Debentures. Without the Paying Agent's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any 2031 Debentures shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Paying Agent as set forth in this Indenture, and the Company agrees to indemnify the Paying Agent from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any 2031 Debentures between the Company and such purchasers, including the costs and expenses incurred by the Paying Agent in the defense of any claim or liability reasonably incurred without negligence or bad faith on its part arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture, in accordance with the indemnity provisions applicable to the Trustee set forth herein. Section 216 Conversion and Repurchase. The Indenture is hereby amended, subject to Section 201 hereof and with respect to the 2031 Debentures only, by adding the following Articles Fourteen, Fifteen and Sixteen to the Indenture: ARTICLE FOURTEEN CONVERSION SECTION 1401 Conversion Privilege. 2031 Debentures shall be convertible in accordance with their terms and in accordance with this Article. A Holder of a 2031 Debenture may convert the principal amount of such 2031 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 2031 Debentures, at the Conversion Rate then in effect. In case a 2031 29 33 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 2031 Debenture or such earlier date as the Holder presents such 2031 Debenture 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 2031 Debenture is redeemed). The number of shares of Common Stock issuable upon conversion of a 2031 Debenture per $1,000 of principal amount thereof (the "Conversion Rate") shall be that set forth under the caption "Conversion" in the 2031 Debentures, subject to adjustment as herein set forth. Provisions of this Indenture that apply to conversion of all of a 2031 Debenture also apply to conversion of a portion of a 2031 Debenture. The Holders' rights to convert 2031 Debentures into Common Stock is subject to the Company's right to elect instead to pay each such Holder the amount of cash set forth in the next succeeding sentence, in lieu of delivering such Common Stock; provided, however, that if an Event of Default (other than a default in a cash payment upon conversion of the 2031 Debentures) shall have occurred and be continuing, the Company shall deliver Common Stock (and cash in lieu of fractional shares of Common Stock) in accordance with this Article Fourteen, whether or not the Company has delivered a notice pursuant to Section 1104 of the Indenture or Section 1402 hereof to the effect that the Debentures would be paid in cash. The amount of cash to be paid pursuant to Section 1402 hereof for each $1,000 of principal amount of a 2031 Debenture upon conversion shall be equal to the average Sale Price of the Common Stock for the five consecutive trading days immediately following (i) the date of the Company's notice of its election to deliver cash upon conversion, if the Company shall not have given a notice of redemption pursuant to Section 1104 of the Indenture, or (ii) the Conversion Date, in the case of a conversion following such a notice of redemption specifying an intent to deliver cash upon conversion, in either case multiplied by the Conversion Rate in effect on such Conversion Date. The Company shall not pay cash in lieu of delivering Common Stock upon the conversion of any 2031 Debenture pursuant to the terms of this Article Fourteen (other than cash in lieu of fractional shares pursuant to Section 1403 hereof) if there has occurred (prior to, on or after, as the case may be, the Conversion Date or the date on which the Company delivers its notice of whether such 2031 Debenture shall be converted into Common Stock or cash pursuant to Section 1402 hereof) and is continuing an Event of Default (other than a default in a cash payment upon conversion of such 2031 Debentures). A 2031 Debenture in respect of which a Holder has delivered a Repurchase Notice or Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such 2031 Debenture, may be converted only if such notice of exercise is withdrawn in accordance with the terms of this Indenture. A Holder of 2031 Debentures is not entitled to any rights 30 34 of a holder of Common Stock until such Holder has converted its 2031 Debentures to Common Stock, and only to the extent such 2031 Debentures are deemed to have been converted into Common Stock pursuant to this Article Fourteen. SECTION 1402 Conversion Procedure. To convert a 2031 Debenture, a Holder must (a) complete and manually sign the conversion notice on the back of the 2031 Debenture and deliver such notice to a Conversion Agent, (b) surrender the 2031 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." Within two Business Days following the Conversion Date, the Company shall deliver to the Holder, through the Conversion Agent, written notice of whether such 2031 Debentures shall be converted into Common Stock or paid in cash, unless the Company shall have delivered such notice previously pursuant to Section 1104 of the Indenture. If the Company shall have notified the Holder that all of such 2031 Debentures shall be converted into Common Stock, the Company shall deliver to the Holder through the Conversion Agent, as soon as practicable but in any event no later than the fifth Business Day following the Conversion Date, 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 1403. Except as provided in the last sentence in the third paragraph of Section 1401 hereof, if the Company shall have notified the Holder that all or a portion of such 2031 Debenture shall be paid in cash, the Company shall deliver to the Holder surrendering such 2031 Debenture the amount of cash payable with respect to such 2031 Debenture no later than the tenth Business Day following such Conversion Date, together with a certificate for the number of full shares of Common Stock deliverable upon the conversion and cash in lieu of any fractional share determined pursuant to Section 1403 hereof. Except as provided in the last sentence in the third paragraph of Section 1401 hereof, the Company may not change its election with respect to the consideration to be delivered upon conversion of a 2031 Debenture once the Company has notified the Holder in accordance with this paragraph. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such 2031 Debentures may be surrendered for conversion in accordance with the Applicable Procedures of the Depositary as in effect from time to time. The Person in whose name the Common Stock certificate is registered shall be deemed to be a shareholder of record on the Conversion Date; provided, however, that no surrender of a 2031 Debenture on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the Person or Persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective 31 35 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 2031 Debenture shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a 2031 Debenture, such Person shall no longer be a Holder of such 2031 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 Fourteen. On conversion of a 2031 Debenture, except as provided below in the case of 2031 Debentures or portions thereof called for redemption, (x) that portion of accrued and unpaid interest on the converted 2031 Debenture attributable to the period from the most recent Interest Payment Date (or, if no Interest Payment Date has occurred, from the Issue Date) through the Conversion Date and (y) accrued contingent interest, if any, attributable to the most recent accrual date with respect to the converted 2031 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), or cash in lieu thereof, in exchange for the 2031 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), or cash in lieu thereof, shall be treated as issued, to the extent thereof, first in exchange for accrued and unpaid interest through the Conversion Date and any accrued contingent interest, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment), or cash in lieu thereof, shall be treated as issued in exchange for the principal amount of the 2031 Debenture being converted pursuant to the provisions hereof. If a Holder converts more than one 2031 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 2031 Debentures converted. Upon surrender of a 2031 Debenture that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new 2031 Debenture equal in principal amount to the principal amount of the unconverted portion of the 2031 Debenture surrendered. 2031 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 2031 Debentures or portions thereof have been called for redemption on a Redemption Date within such period) be accompanied 32 36 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 2031 Debentures or portions thereof being surrendered for conversion. 2031 Debentures or portions thereof surrendered for conversion during the period from the close of business on any date on which contingent interest accrues to the opening of business on the date on which such contingent interest is payable shall (unless such 2031 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 contingent interest payable on such contingent interest payment date on the principal amount of 2031 Debentures or portions thereof being surrendered for conversion. SECTION 1403 Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Security. Instead, the Company will deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined, to the nearest 1/1,000th of a share, by multiplying the Sale Price on the Trading Day immediately prior to the Conversion Date, of a full share by the fractional amount and rounding the product to the nearest whole cent. SECTION 1404 Taxes on Conversion. If a Holder converts a 2031 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. SECTION 1405 Company to Provide Common Stock. The Company shall, prior to issuance of any 2031 Debentures under this Article Fourteen, 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 2031 Debentures Outstanding into shares of Common Stock. All shares of Common Stock delivered upon conversion of the 2031 Debentures shall be newly issued shares, shall be duly 33 37 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 2031 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 Common Stock are then listed or quoted. SECTION 1406 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: (a) In case the Company shall (i) pay a dividend on its Common Stock in shares of Common Stock, (ii) make a distribution on its Common Stock in shares of Common Stock, (iii) subdivide its outstanding Common Stock into a greater number of shares, or (iv) combine its outstanding Common Stock into a smaller number of shares, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the Holder of any 2031 Debenture thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have owned had such 2031 Debenture been converted immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of subdivision or combination. (b) In case the Company shall issue rights or warrants to all or substantially all holders of its Common Stock entitling them (for a period commencing no earlier than the record date described below and expiring not more than 60 days after such record date) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the current market price per share of Common Stock (as determined in accordance with subsection (e) of this Section 1406) on the record date for the determination of shareholders 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 such record date 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 34 38 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 subsection (e) of this Section 1406) 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. If at the end of the period during which such rights or warrants are exercisable not all rights or warrants shall have been exercised, the adjusted Conversion 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). (c) In case the Company shall distribute to all or substantially 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 1406(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 1406(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 by a fraction of which the numerator shall be the current market price per share (as determined in accordance with subsection (e) of this Section 1406) of the Common Stock on the record date mentioned below, and of which the denominator shall be the current market price per share (as determined in accordance with subsection (e) of this Section 1406) of the Common Stock on such record date less the fair market value on such record 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 or other non-cash assets so distributed 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 after the record date for the determination of shareholders entitled to receive such distribution. In the event that the Company implements a shareholder rights plan, such rights plan shall provide, subject to customary exceptions and limitations, that upon conversion of the 2031 Debentures the Holders will receive, in addition to the Common Stock issuable upon such conversion, the rights issued under such rights plan (notwithstanding the occurrence of an event causing such rights to separate from the Common Stock at or prior to the time of conversion). Any 35 39 distribution of rights or warrants pursuant to a shareholder rights plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants for the purposes of this Section 1406(c). Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 1406(c) (and no adjustment to the Conversion Rate under this Section 1406(c) will be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different securities, evidences of indebtedness or other assets or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and record date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 1406(c), (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants all of which shall have expired or been terminated without exercise, the Conversion Rate shall be readjusted as if such rights and warrants had never been issued. (d)(1) In case the Company shall, by dividend or otherwise, at any time distribute (a "Triggering Distribution") to all or substantially all holders of its Common Stock all-cash distributions in an aggregate amount that, together with the aggregate amount of (A) any cash and the 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) of any other consideration payable in respect of any tender offer by the Company or a Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of payment of the Triggering Distribution and in respect of which no Conversion Rate adjustment pursuant to this Section 1406 has been made and (B) all other cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the date of payment of the Triggering Distribution and in 36 40 respect of which no Conversion Rate adjustment pursuant to this Section 1406 has been made, exceeds an amount equal to 12.5% of the product of the current market price per share of Common Stock (as determined in accordance with subsection (e) of this Section 1406) on the Business Day (the "Determination Date") immediately preceding the day on which such Triggering Distribution is declared by the Company multiplied by the number of shares of Common Stock outstanding on the Determination Date (excluding shares held in the treasury of the Company), the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying such Conversion Rate in effect immediately prior to the Determination Date by a fraction of which the numerator shall be such current market price per share of Common Stock (as determined in accordance with subsection (e) of this Section 1406) on the Determination Date, and the denominator shall be the current market price per share of Common Stock (as determined in accordance with subsection (e) of this Section 1406) on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (determined as aforesaid) of any such other consideration so distributed, paid or payable within such 12 months (including, without limitation, the Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Determination Date), such increase to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. (2) In case any tender offer made by the Company or any of its Subsidiaries for Common Stock shall expire and such tender offer (as amended upon the expiration thereof) shall involve the payment of aggregate consideration in an amount (determined as the sum of the aggregate amount of cash consideration and the aggregate fair market value (as 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 consideration) that, together with the aggregate amount of (A) any cash and the 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) of any other consideration payable in respect of any other tender offers by the Company or any Subsidiary of the Company for Common Stock consummated within the 12 months preceding the date of the Expiration Date (as defined below) and in respect of which no Conversion Rate adjustment pursuant to this Section 1406 has been made and (B) all cash distributions to all or substantially all holders of its Common Stock made within the 12 months preceding the Expiration Date and in respect of which no Conversion Rate adjustment pursuant to this Section 1406 has been made, exceeds an amount equal to 12.5% of the product of the current market price per 37 41 share of Common Stock (as determined in accordance with subsection (e) of this Section 1406) as of the last date (the "Expiration Date") tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes Called the "Expiration Time') multiplied by the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time, then, immediately prior to the opening of business on the day after the Expiration Date, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to 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 Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the current market price per share of Common Stock (as determined in accordance with subsection (e) of this Section 1406) on the Trading Day next succeeding the Expiration Date, and 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 subsection (e) of this Section 1406) 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. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion 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 1406(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 1406(d)(2). (3) For purposes of this Section 1406(d), the term "tender offer" shall mean and include both tender offers and exchange offers, all references to "purchases" of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all references to "tendered shares" (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. 38 42 (e) For the purpose of any computation under subsections (b), (c) and (d) of this Section 1406, 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 30 consecutive Trading Days commencing 45 Trading Days before (i) the Determination Date or the Expiration Date, as the case may be, with respect to distributions or tender offers under subsection (d) of this Section 1406 or (ii) the record date with respect to distributions, issuances or other events requiring such computation under subsection (b) or (c) of this Section 1406. 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 are 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). (f) In any case in which this Section 1406 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 1406, 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 1409) issuing to the Holder of any 2031 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. 39 43 SECTION 1407 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 1407 are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article Fourteen 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. To the extent that the 2031 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 1408 Adjustment for Tax Purposes. The Company shall be entitled to make such adjustments in the Conversion Rate, in addition to those required by Section 1406, 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 1409 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 1410 Notice of Certain Transactions. In the event that: (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 1411, or (3) there is a dissolution or liquidation of the Company, 40 44 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 fifteen days before such date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 1410. SECTION 1411 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 2031 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 2031 Debenture then Outstanding shall have the right to convert such 2031 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 2031 Debenture immediately prior to such reclassification, change, consolidation, merger, sale or conveyance. 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 Fourteen. If, in the case of any such consolidation, 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 2031 Debentures as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 1411 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales or conveyances. 41 45 In the event the Company shall execute a supplemental indenture pursuant to this Section 1411, 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 2031 Debentures upon the conversion of their 2031 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 1412 Trustee's Disclaimer. The Trustee shall have no duty to determine when an adjustment under this Article Fourteen 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 1409. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of 2031 Debentures, and the Trustee shall not be responsible for the Company's failure to comply with any provisions of this Article Fourteen. The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 1411, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 1411. SECTION 1413 Voluntary Increase. The Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days or such longer period as may be required by law and if the increase is irrevocable during the period. ARTICLE FIFTEEN REPURCHASE OF SECURITIES AT OPTION OF THE HOLDER SECTION 1501 General. The Company may be required to repurchase 2031 Debentures in accordance with their terms and in accordance with this Article. 42 46 2031 Debentures shall be purchased by the Company pursuant to the terms and conditions under the caption "Repurchase by the Company at the Option of the Holder" in the 2031 Debentures on April 15, 2008 (the "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 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 2031 Debenture which the Holder will deliver to be repurchased, (B) the portion of the principal amount of the 2031 Debenture which the Holder will deliver to be repurchased, which portion must be $1,000 or an integral multiple thereof, (C) that such 2031 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 2031 Debentures and in this Indenture, (D) in the event that the Company elects, pursuant to Section 1502 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 1503 hereof, whether such Holder elects (i) to withdraw such Repurchase Notice as to some or all of the 2031 Debentures to which such Repurchase Notice relates (stating the principal amount and certificate numbers of the 2031 Debentures as to which such withdrawal shall relate), or (ii) to receive cash in respect of the entire Repurchase Price for all 2031 Debentures (or portions thereof) to which such Repurchase Price relates, and (2) delivery of such 2031 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 Fifteen only if the 2031 Debenture so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice. 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 1509 43 47 hereof, fails to indicate such Holder's choice with respect to the election set forth in clause (D) of Section 1501(1), such Holder shall be deemed to have elected to receive cash in respect of the Repurchase Price for all 2031 Debentures subject to the Repurchase Notice in the circumstances set forth in such clause (D). The Company shall purchase from the Holder thereof, pursuant to this Article Fifteen, a portion of a 2031 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 2031 Debenture also apply to the purchase of such portion of such 2031 Debenture. Any purchase by the Company contemplated pursuant to the provisions of this Article Fifteen shall be consummated by the delivery of the consideration to be received by the Holder (together with accrued and unpaid contingent interest, if any) promptly following the later of the Repurchase Date and the time of delivery of the 2031 Debenture. Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 1501 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 1509. The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof. SECTION 1502 The Company's Right to Elect Manner of Payment of Repurchase Price. (a) The Repurchase Price of 2031 Debentures in respect of which a Repurchase Notice pursuant to Section 1501 has been given, or a specified percentage thereof, 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 Section 1502 and 1503 hereof. The Company shall designate, in the Company Notice delivered pursuant to Section 1505 hereof, whether the Company will purchase the 2031 Debentures for cash or Common Stock, or, if a combination thereof, the percentages of the Repurchase Price of 2031 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 2031 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 2031 Debentures are purchased pursuant to this Article Fifteen shall receive the same percentage of cash or Common Stock in payment of the Repurchase Price for such 2031 Debentures, except (i) as provided 44 48 in Section 1504 with regard to the payment of cash in lieu of fractional Common Stock and (ii) in the event that the Company is unable to purchase the 2031 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 2031 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 1502 or pursuant to Section 1504 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 1505, (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 1504 have been or will be complied with, and (iv) whether the Company desires the Trustee to give the Company Notice required by Section 1505. SECTION 1503 Purchase with Cash. On each Repurchase Date, at the option of the Company, the Repurchase Price of 2031 Debentures in respect of which a Repurchase Notice pursuant to Section 1501 has been given, or a specified percentage thereof, may be paid by the Company with cash equal to the aggregate Repurchase Price of such 2031 Debentures. If the Company elects to purchase 2031 Debentures with cash, the Company Notice, as provided in Section 1505, 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 1504 Payment by Issuance of Common Stock. On each Repurchase Date, at the option of the Company, the Repurchase Price of 2031 Debentures in respect of which a Repurchase Notice pursuant to Section 1501 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 45 49 percentage, as the case may be, of the Repurchase Price of such 2031 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 2031 Debenture repurchased, the number of shares of Common Stock shall be based on the aggregate amount of 2031 Debentures to be repurchased. If the Company elects to purchase the 2031 Debentures by the issuance of Common Stock, the Company Notice, as provided in Section 1505, shall be sent to the Holders (and to beneficial owners as required by applicable law) not later than the Company Notice Date. The Company's right to exercise its election to purchase the 2031 Debentures pursuant to this Article Fifteen 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 2031 Debentures with Common Stock as provided herein; (ii) the listing of shares of Common Stock to be issued in respect of the payment of the Repurchase Price on the principal United States securities exchange on which the Common Stock is then listed or, if not so listed, the quotation of such shares on Nasdaq; (iii) the registration of the shares of 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; (iv) any necessary qualification or registration under applicable state securities laws or the availability of an exemption from such qualification and registration; and (v) 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 Common Stock to be issued by the Company in payment of the Repurchase Price in respect of 2031 Debentures have been duly authorized and, when issued and delivered pursuant to 46 50 the terms of this Indenture in payment of the Repurchase Price in respect of the 2031 Debentures, will be validly issued, fully paid and non-assessable 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) (iii) and (iv) 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 2031 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 information necessary to calculate the Market Price is published in The Wall Street Journal or another daily newspaper of national circulation. 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 2031 Debentures pursuant to this Article Fifteen through the issuance of Common Stock, the Company shall pay, without further notice, the entire Repurchase Price of the 2031 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 the third Business Day (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 1406; subject, however, to the conditions set forth in Sections 1406(f) and 1407. 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 by the National Quotation Bureau Incorporated. 47 51 SECTION 1505 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 1503 or 1504, as applicable (the "Company Notice"). Such Company Notice shall state the manner of payment elected and shall contain the following information: In the event the Company has elected to pay the Repurchase Price (or a specified percentage thereof) with Common Stock, the Company Notice shall: (1) state that each Holder will receive Common Stock with a Market Price equal to such specified percentage of the Repurchase Price of the 2031 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, the Conversion Rate and, to the extent known at the time of such notice, the amount of contingent interest, if any, that will be accrued and payable with respect to the 2031 Debentures as of the Repurchase Date; (B) the name and address of the Paying Agent and the Conversion Agent; (C) that 2031 Debentures as to which a Repurchase Notice has been given may be converted pursuant to Article Fourteen hereof only if the applicable Repurchase Notice has been withdrawn in accordance with the terms of this Indenture; (D) that 2031 Debentures must be surrendered to the Paying Agent to collect payment of the Purchase Price and contingent interest, if any; (E) that the Repurchase Price for any 2031 Debenture as to which a Repurchase Notice has been given and not withdrawn, together with any accrued contingent interest payable with respect thereto, will be paid promptly following 48 52 the later of the Repurchase Date and the time of surrender of such 2031 Debenture as described in (D); (F) the procedures the Holder must follow to exercise repurchase rights under this Article Fifteen and a brief description of those rights; (G) briefly, the conversion rights of the 2031 Debentures; and (H) the procedures for withdrawing a Repurchase Notice (including, without limitation, for a conditional withdrawal pursuant to the terms of Section 1501 or 1509). If any of the 2031 Debentures is in the form of a Global Security, then the Company shall modify the Company Notice to the extent necessary to accord with the procedures of the Depositary applicable to the repurchase of Global Securities. At the Company's 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 2031 Debentures, the Company 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 1506 Covenants of the Company. All Common Stock delivered upon purchase of the 2031 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. SECTION 1507 Procedure upon Repurchase. The Company shall deposit cash (in respect of a cash purchase under Section 1503 or for fractional Common Stock or contingent interest as applicable) or Common Stock, or a combination thereof, as applicable, at the time and in the manner as provided in Section 1510, sufficient to pay the aggregate Repurchase Price of, and any accrued and unpaid contingent interest with respect to, all 2031 Debentures to be purchased on the applicable Repurchase Date pursuant to this Article Fifteen. 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 full shares of Common Stock issuable in payment of the Repurchase Price and cash in lieu of any fractional shares of 49 53 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 1504, 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 1508 Taxes. If a Holder of a 2031 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 1509 Effect of Repurchase Notice. Upon receipt by the Paying Agent of the Repurchase Notice specified in Section 1505, the Holder of the 2031 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 and any accrued and unpaid contingent interest with respect to such 2031 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 2031 Debenture (provided the conditions in Section 1501 have been satisfied) and (y) the time of delivery of such 2031 Debenture to the Paying Agent by the Holder thereof in the manner required by Section 1501. 2031 Debentures in respect of which a Repurchase Notice has been given by the Holder thereof may not be converted pursuant to Article Fourteen 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 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 2031 Debenture in respect of which such notice of withdrawal is being submitted; (2) the principal amount of the 2031 Debenture with respect to which such notice of withdrawal is being submitted; and 50 54 (3) the principal amount, if any, of such 2031 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 1501(1)(D) or (ii) a conditional withdrawal containing the information set forth in Section 1501(l)(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 2031 Debentures pursuant to this Article Fifteen (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 2031 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 2031 Debentures). The Paying Agent will promptly return to the respective Holders thereof any 2031 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 2031 Debentures) in which case, upon such return, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn. SECTION 1510 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 the aggregate Repurchase Price of, and any accrued and unpaid contingent interest with respect to, all of the 2031 Debentures or portions thereof which are to be purchased as of the Repurchase Date. The manner in which the deposit required by this Section 1510 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 Repurchase Date. If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Repurchase Price of, and any accrued and unpaid contingent interest with respect to, any 2031 Debenture for which a Repurchase Notice has been tendered and not withdrawn in accordance with this Indenture then, immediately after Repurchase Date, such 2031 Debenture will cease to be 51 55 Outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Repurchase Price and accrued and unpaid contingent interest, if any, as aforesaid).

ARTICLE SIXTEEN PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON CHANGE IN CONTROL SECTION 1601 Right to Require Repurchase. (a) If at any time that 2031 Debentures remain Outstanding there shall occur a Change in Control, 2031 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 Change in Control (the "Change in Control Purchase Date") at a purchase price specified in the 2031 Debentures (the "Change in Control Purchase Price"), subject to satisfaction by or on behalf of any Holder of the requirements set forth in subsection (c) of this Section 1601. A "Change in Control" shall be deemed to have occurred at such time as (a) any Person, or any Persons acting together in a manner which would constitute a "group" (a "Group") for purposes of Section 13(d) of the Exchange Act, or any successor provision thereto, together with any Affiliates thereof (in each case, excluding Permitted Holders) become the Beneficial Owners, directly or indirectly, of capital stock of the Company, entitling such Person or Persons and its or their Affiliates to exercise more than 50% of the total voting power of all classes of the Company's capital stock entitled to vote generally in the election of the Company's directors or (b) the Company shall consolidate with or merge into any other Person (other than a Subsidiary), or any other Person (other than a Subsidiary) shall consolidate with or merge into the Company, or the Company shall sell, convey, transfer or lease its properties and assets substantially as an entirety to any Person other than a Subsidiary, and, in the case of any such transaction the outstanding Common Stock is reclassified into, exchanged for or converted into the right to receive any other property or security, unless the stockholders of the Company immediately before such transaction, own, directly 53 57 or indirectly, immediately following such transaction, at least a majority of the combined voting power of the outstanding voting securities of the Person resulting from such transaction or the Person acquiring such properties and assets, entitled to vote generally on the election of such resulting or acquiring Person's directors, in substantially the same proportion as their ownership of the Common Stock immediately before such transaction, provided, however, that, with respect to both clause (a) and (b) a Change in Control shall not be deemed to have occurred if at least 50% of the consideration (excluding cash payments for fractional shares) in the transaction or transactions constituting the Change in Control consists of shares of voting common stock of such Person that are, or upon issuance will be, traded on a United States national securities exchange or approved for trading on an established automated over-the counter trading market in the United States. The term "Beneficial Owner" shall be determined in accordance with Rules 13d-3 and 13d-5 promulgated by the Securities and Exchange Commission under the Exchange Act or any successor provision thereto, except that a Person shall be deemed to have "beneficial ownership" of all shares that such Person has the right to acquire, whether such right is exercisable immediately or only after the passage of time. "Permitted Holders" means Loews Corporation, a Delaware corporation, and any of its Subsidiaries. (b) Within 15 Business Days after the occurrence of a Change in Control, the Company shall mail a written notice of the Change in Control to the Trustee and to each Holder. The notice shall include the form of a Change in Control Purchase Notice to be completed by the Holder and shall state: (1) the date of such Change in Control and, briefly, the events causing such Change in Control; (2) the date by which the Change in Control Purchase Notice pursuant to this Section 1601 must be given; (3) the Change in Control Purchase Date; (4) the Change in Control Purchase Price and, to the extent known at the time of such notice, the amount of contingent interest, if any, that will be accrued and payable with respect to the 2031 Debentures as of the Change in Control Purchase Date; (5) briefly, the conversion rights of the 2031 Debentures; (6) the name and address of each Paying Agent and Conversion Agent; 54 58 (7) the Conversion Rate and any adjustments thereto; (8) that 2031 Debentures as to which a Change in Control Purchase Notice has been given may be converted into Common Stock pursuant to Article Fourteen only to the extent that the Change in Control Purchase Notice has been withdrawn in accordance with the terms of this Indenture; (9) the procedures that the Holder must follow to exercise rights under this Section 1601; (10) the procedures for withdrawing a Change in Control Purchase Notice, including a form of notice of withdrawal; and (11) that the Holder must satisfy the requirements set forth in the 2031 Debentures in order to convert the 2031 Debentures. If any of the 2031 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 subsection (a) of this Section 1601 upon delivery of a written notice (which shall be in substantially the form included as an attachment to the 2031 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 "Change in Control Purchase Notice") to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Change in Control Purchase Date. The delivery of such 2031 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 Change in Control Purchase Price and accrued and unpaid contingent interest, if any. The Company shall purchase from the Holder thereof, pursuant to this Section 1601, a portion of a 2031 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 2031 Debenture pursuant to Sections 1601 through 1606 also apply to the purchase of such portion of such 2031 Debenture. Any purchase by the Company contemplated pursuant to the provisions of this Section 1601 shall be consummated by the delivery of the consideration to be received by the Holder (together with accrued and unpaid contingent interest, if any) promptly following the later of the Change in Control Purchase Date and the 55 59 time of delivery of the 2031 Debenture to the Paying Agent in accordance with this Section 1601. Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Change in Control Purchase Notice contemplated by this subsection (c) shall have the right to withdraw such Change in Control Purchase Notice in whole or 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 Change in Control Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 1602. A Paying Agent shall promptly notify the Company of the receipt by it of any Change in Control Purchase Notice or written withdrawal thereof. Anything herein to the contrary notwithstanding, in the case of Global Securities, any Change in Control Purchase Notice may be delivered or withdrawn and such 2031 Debentures may be surrendered or delivered for purchase in accordance with the applicable procedures of the Depositary as in effect from time to time. SECTION 1602 Effect of Change in Control Purchase Notice. Upon receipt by any Paying Agent of the Change in Control Purchase Notice specified in Section 1601(c), the Holder of the 2031 Debenture in respect of which such Change in Control Purchase Notice was given shall (unless such Change in Control Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Change in Control Purchase Price and any accrued and unpaid contingent interest, if any, with respect to such 2031 Debenture. Such Change in Control Purchase Price and accrued and unpaid contingent interest, if any, shall be paid to such Holder promptly following the later of (a) the Change in Control Purchase Date with respect to such 2031 Debenture (provided the conditions in Section 1601(c) have been satisfied) and (b) the time of delivery of such 2031 Debenture to a Paying Agent by the Holder thereof in the manner required by Section 1601(c). 2031 Debentures in respect of which a Change in Control 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 Change in Control Purchase Notice unless such Change in Control Purchase Notice has first been validly withdrawn as specified in the following paragraph. A Change in Control Purchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Change in Control Purchase Notice at any time prior to the close of business on the applicable Change in Control Purchase Date specifying: 56 60 (1) the certificate number of the 2031 Debenture in respect of which such notice of withdrawal is being submitted; (2) the principal amount of the 2031 Debenture with respect to which such notice of withdrawal is being submitted; and (3) the principal amount, if any, of such 2031 Debenture which remains subject to the original Change in Control Purchase Notice and which has been or will be delivered for purchase by the Company. There shall be no purchase of any 2031 Debentures pursuant to this Article Sixteen if there has occurred (prior to, on or after, as the case may be, the giving, by the Holders of such 2031 Debentures, of the required Change in Control Purchase Notice) and is continuing an Event of Default (other than a default in the payment of the Change in Control Purchase Price with respect to such 2031 Debentures). The Paying Agent will promptly return to the respective Holders thereof any 2031 Debentures (x) with respect to which a Change in Control Purchase 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 Change in Control Purchase Price with respect to such 2031 Debentures) in which case, upon such return, the Change in Control Purchase Notice with respect thereto shall be deemed to have been withdrawn. SECTION 1603 Deposit of Change in Control Purchase Price. On or before 11:00 a.m. New York City time on the Change in Control Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent (other than the Company or an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Business Day) sufficient to pay the aggregate Change in Control Purchase Price of, and any accrued and unpaid contingent interest with respect to, all the 2031 Debentures or portions thereof that are to be purchased as of such Change in Control Purchase Date. The manner in which the deposit required by this Section 1603 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 Change in Control Purchase Date. If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Change in Control Purchase Price of, and any accrued and unpaid contingent interest with respect to, any 2031 Debenture for which a Change in Control Purchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on the Change in Control Purchase Date, such 2031 Debenture will cease to be Outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Change in Control Purchase Price and any accrued and unpaid contingent interest as 57 61 aforesaid). The Company shall publicly announce the principal amount of 2031 Debentures purchased as a result of such Change in Control on or as soon as practicable after the Change in Control Purchase Date. SECTION 1604 Securities Purchased In Part. Any 2031 Debenture that is to be purchased only in part shall be surrendered at the office of a Paying Agent and promptly after the Change in Control Purchase Date the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such 2031 Debenture, without service charge, a new 2031 Debenture or 2031 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 2031 Debenture so surrendered that is not purchased. SECTION 1605 Compliance With Securities Laws Upon Purchase of Securities. In connection with any offer to purchase or purchase of 2031 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), if required, under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Article Sixteen to be exercised in the time and in the manner specified in this Article Sixteen. SECTION 1606 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash or Common Stock that remains 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 Change in Control Purchase Price or contingent interest, if any; provided, however, that to the extent that the aggregate amount of cash or Common Stock deposited by the Company pursuant to Section 1603 exceeds the aggregate Change in Control Purchase Price of, and any accrued and unpaid contingent interest with respect to, the 2031 Debentures or portions thereof which the Company is obligated to purchase as of the Change in Control Purchase Date, then on 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. Thereafter, any Holder entitled to payment must look to the Company for payment as general creditors, unless an applicable abandoned property law designates another Person. 58 62 Section 216 Interpretation of Indenture.

INTEREST ON OVERDUE AMOUNTS 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 Change in Control Purchase Price pursuant to "Purchase of 2031 Debentures at Option of Holder Upon a Change in Control", 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 2031 Debenture) or if interest (including contingent 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 1 1/2% per annum, compounded semiannually, 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. METHOD OF PAYMENT Payments in respect of principal of and interest, if any, on the 2031 Debentures shall be made by the Company in immediately available funds. PAYING AGENT, CONVERSION AGENT, SECURITY REGISTRAR AND BID SOLICITATION AGENT. Initially, the Trustee will act as Paying Agent, Conversion Agent, Security Registrar and Bid Solicitation Agent. The Company may appoint and change any Paying Agent, Conversion A-7 74 Agent, Security Registrar or co-registrar or Bid Solicitation Agent without notice, other than notice to the Trustee, except that the Company will maintain at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan, which shall initially be an office or agency of the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Security Registrar or co-registrar. None of the Company, any of its Subsidiaries or any of their Affiliates shall act as Bid Solicitation Agent. CONTINGENT INTEREST Subject to the accrual and record date provisions hereinafter specified, the Company shall pay contingent interest to the Holders during any six-month period (a "Contingent Interest Period") from April 16 to October 15 and from October 16 to April 15, commencing April 16, 2008, if the average Debenture Market Price of a 2031 Debenture for the Five-Day Period with respect to such Contingent Interest Period equals $1,200 or more and the Company pays a Regular Cash Dividend during such Contingent Interest Period. The amount of contingent interest payable per $1,000 principal amount of 2031 Debentures in respect of any Quarterly Period within a Contingent Interest Period shall equal 50% of Regular Cash Dividends, if any, paid by the Company per share of Common Stock during that Quarterly Period multiplied by the Conversion Rate in effect on the date on which such contingent interest accrues. Contingent interest, if any, will accrue and be payable to Holders as of the record date for the related Regular Cash Dividend. Such contingent interest shall be paid on the payment date of the related Regular Cash Dividend. Interest on this 2031 Debenture will continue to accrue at 1 1/2% per annum whether or not contingent interest is paid. "Five-Day Period" means, with respect to any Contingent Interest Period, the five trading days ending on the second trading day immediately preceding the first day of such Contingent Interest Period; provided, however, if the Company shall have declared a Regular Cash Dividend on its Common Stock that is payable during such Contingent Interest Period but for which the record date for determining stockholders entitled thereto precedes the first day of such Contingent Interest Period, then "Five-Day Period" shall mean, with respect to such Contingent Interest Period, the five trading days ending on the second trading day immediately preceding such record date. "Regular Cash Dividends" means quarterly or other periodic cash dividends on the Company's Common Stock as declared by the Company's Board of Directors as part of its cash dividend payment practices and that are not designated by such Board of Directors as extraordinary or special or other nonrecurring dividends. "Debenture Market Price" means, as of any date of determination, the average of the secondary market bid quotations per $1,000 principal amount of 2031 Debentures obtained by the Bid Solicitation Agent for $10 million principal amount of 2031 Debentures at approximately 4:00 p.m., New York City time, on such determination date from three recognized securities dealers in The City of New York (none of which shall be an Affiliate of the Company) selected by the Company; provided, however, if (a) at least three such bids are not obtained by the Bid A-8 75 Solicitation Agent or (b) in the Company's reasonable judgment, the bid quotations are not indicative of the secondary market value of the 2031 Debentures as of such determination date, then the Debenture Market Price for such determination date shall equal (i) the Conversion Rate in effect as of such determination date multiplied by (ii) the average Sale Price for the five Trading Days ending on such determination 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 determination date, of any event described in Section 1406 of the Indenture. The term "Quarterly Period" shall mean, with respect to any Contingent Interest Period, any quarterly period within such Contingent Interest Period extending from April 16 to July 15, from July 16 to October 15, from October 16 to January 15, or from January 16 to April 15. Upon a determination by the Company that Holders will be entitled to receive contingent interest which may become payable during a Contingent Interest Period, on or prior to the first day of such Contingent Interest Period, the Company shall issue a press release and publish such information on its web site on the World Wide Web or through such other public medium as the Company may use at that time. OPTIONAL REDEMPTION No sinking fund is provided for the 2031 Debentures. At any time on or after April 15, 2008, the 2031 Debentures are redeemable as a whole at any time, or in part from time to time, at the option of the Company in accordance with the Indenture at a Redemption Price equal to 100% of the principal amount of the Debentures to be redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date. In addition to the Redemption Price payable with respect to all 2031 Debentures or portions thereof to be redeemed as of a Redemption Date, the Holders of such 2031 Debentures (or portions thereof) shall be entitled to receive accrued and unpaid contingent interest, if any, with respect thereto, which contingent interest shall be paid in cash on the Redemption Date. If the Company redeems less than all of the outstanding 2031 Debentures, the Trustee will select the 2031 Debentures 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 2031 Debentures for partial redemption and the Holder converts a portion of the same 2031 Debentures, the converted portion will be deemed to be from the portion selected for redemption. NOTICE OF REDEMPTION Notice of redemption will be mailed by first-class mail at least 15 days but not more than 60 days before the Redemption Date to each Holder of 2031 Debentures to be redeemed at its registered address. 2031 Debentures 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 plus any accrued and unpaid contingent interest, all interest and contingent interest shall cease to accrue on the 2031 Debentures or portions thereof called for redemption. A-9 76 PURCHASE OF 2031 DEBENTURES AT OPTION OF HOLDER UPON A CHANGE IN CONTROL At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the 2031 Debentures held by such Holder on the date that is 35 Business Days after the occurrence of a Change in Control, at a Change in Control Purchase Price equal to the 100% of the principal amount of the 2031 Debentures to be purchased plus accrued and unpaid interest to, but excluding, the Change in Control Purchase Date. The Holder shall have the right to withdraw any Change in Control Purchase Notice (in whole or in a portion thereof that is $1,000 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 Change in Control Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. In addition to the Change in Control Purchase Price payable with respect to all 2031 Debentures or portions thereof to be purchased as of a Change in Control Purchase Date, the Holders of such 2031 Debentures (or portions thereof) shall be entitled to receive accrued and unpaid contingent interest, if any, with respect thereto, which contingent interest shall be paid in cash promptly following the later of the Change in Control Purchase Date and the time of delivery of such 2031 Debentures to the Paying Agent pursuant to the Indenture. If cash sufficient to pay the Change in Control Purchase Price of, together with any accrued and unpaid contingent interest with respect to, all 2031 Debentures or portions thereof to be purchased as of the Change in Control Purchase Date, is deposited with the Paying Agent on the Business Day following the Change in Control Purchase Date, all interest and contingent interest, if any, shall cease to accrue on such 2031 Debentures (or portions thereof) immediately after such Change in Control Purchase Date, and the Holder thereof shall have no other rights as such (other than the right to receive the Change in Control Purchase Price, and accrued and unpaid contingent interest, if any, upon surrender of such 2031 debenture). CONVERSION A Holder of a 2031 debenture may convert the 2031 debenture into shares of Common Stock at any time until the close of business on April 15, 2031; provided, however, that if the 2031 Debenture 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 2031 Debenture or such earlier date as the Holder presents such 2031 debenture 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 2031 debenture is redeemed). A 2031 Debenture in respect of which a Holder has delivered a Repurchase Notice or a Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such 2031 Debenture may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture. The initial Conversion Rate is 20.3978 shares of Common Stock per $1,000 principal amount, subject to A-10 77 adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock. A Holder's right to convert the 2031 Debentures into Common Stock of the Company is also subject to the Company's right to elect to pay such Holder the amount of cash set forth in the next succeeding sentence in lieu of delivering all or part of such Common Stock; provided, however, that if such payment of cash is not permitted pursuant to the provisions of the Indenture, the Company shall deliver Common Stock (and cash in lieu of fractional shares of Common Stock) in accordance with the Indenture, whether or not the Company has delivered a notice pursuant to the Indenture to the effect that the 2031 Debentures will be paid in cash. The amount of cash to be paid for each $1,000 principal amount of a 2031 Debenture shall be equal to the average Sale Price of a share of Common Stock of the Company for the five consecutive Trading Days immediately following (i) the date of the Company's notice of its election to deliver cash upon conversion, if the Company shall not have given a notice of redemption pursuant to the Indenture, or (ii) the Conversion Date, in the case of a conversion following such a notice of redemption specifying an intent to deliver cash upon conversion, in either case multiplied by the Conversion Rate in effect on such Conversion Date. If the Company shall elect to make such payment wholly in shares of Common Stock, then such shares shall be delivered through the Conversion Agent to Holders surrendering 2031 Debentures as promptly as practicable but in any event no later than the fifth Business Day following the Conversion Date. If, however, the Company shall elect to make any portion of such payment in cash, then the payment, including any delivery of shares of Common Stock, shall be made to Holders surrendering 2031 Debentures no later than the tenth Business Day following the Conversion Date. The Company may not pay cash in lieu of delivering all or part of such shares of Common Stock upon the conversion of any 2031 Debenture pursuant to the terms of the Indenture (other than cash in lieu of fractional shares) if there has occurred (prior to, on or after, as the case may be, the Conversion Date or the date on which the Company delivers its notice specifying whether each Conversion shall be converted into shares of Common Stock or cash) and is continuing an Event of Default (other than a default in such payment on such 2031 Debentures). A Holder may convert a portion of a 2031 Debenture 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 2031 Debenture, except as provided below, (x) that portion of accrued and unpaid interest on the converted 2031 Debenture attributable to the period from the most recent Interest Payment Date (or, if no Interest Payment Date has occurred, from the Issue Date) through the Conversion Date and (y) except as provided below, accrued contingent interest, if any, attributable to the most recent accrual date with respect to the converted 2031 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), or cash in lieu thereof, in exchange for the 2031 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), or cash in lieu thereof, shall be A-11 78 treated as issued in exchange for the principal amount of the 2031 Debenture 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 Sale Price of the Common Stock on the Trading Day immediately prior to the Conversion Date. To convert a 2031 Debenture, 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 2031 Debenture to the 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 2031 Debentures held by such Holder on April 15, 2008 at a Repurchase Price equal to 100% of the principal amount thereof plus accrued and unpaid interest to, but excluding, the Repurchase Date, 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 2031 Debentures to the Paying Agent by the Holder as set forth in the Indenture. The Repurchase Price 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. 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. In addition to the Repurchase Price payable with respect to all 2031 Debentures or portions thereof to be repurchased as of the Repurchase Date, the Holders of such 2031 Debentures (or portions thereof) shall be entitled to receive accrued and unpaid contingent interest, if any, with respect thereto, which contingent interest shall be paid in cash promptly following the later of the Repurchase Date and the time of delivery of such 2031 Debentures to the Paying Agent pursuant to the Indenture. If cash (and/or securities if permitted under the Indenture) sufficient to pay the Repurchase Price of, together with any accrued and unpaid contingent interest with respect to, all 2031 Debentures 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, all interest and contingent interest, if any, shall cease to accrue on such 2031 Debentures (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 and accrued and unpaid contingent interest, if any, upon surrender of such 2031 Debenture). A-12 79 CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION Any 2031 Debentures 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 2031 Debentures at an amount not less than the Redemption Price plus accrued and unpaid contingent interest, if any, thereon, by one or more investment bankers or other purchasers who may agree with the Company to purchase such 2031 Debentures from the Holders, to convert them into Common Stock of the Company and to make payment for such 2031 Debentures to the Paying Agent in trust for such Holders.

The Securities are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof.
