There shall be a series of Securities designated "Zero Coupon Convertible Debentures Due June 6, 2020" of the Company, and the form thereof shall be substantially as set forth in Annex A hereto, which is incorporated into and shall be deemed a part of this Second Supplemental Indenture, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange or as may, consistently herewith, be determined by the officers of the Company executing such 2020 Debentures, as evidenced by their execution of the 2020 Debentures. (a) Restricted Global Securities. All of the 2020 Debentures are initially being offered and sold to qualified institutional buyers as defined in Rule 144A (collectively, "QIBs" or individually a "QIB") in reliance on Rule 144A under the Securities Act and shall be issued initially in the form of one or more Restricted Global Securities, which shall be deposited on behalf of the purchasers of the 2020 Debentures represented thereby with the Trustee, at its Corporate Trust Office, as 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) Global Securities in General. Each Global Security shall represent such of the outstanding 2020 Debentures as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding 2020 Debentures from time to time endorsed thereon and that the aggregate amount of outstanding 2020 Debentures represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions, purchases or conversions of such 2020 Debentures. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the Principal Amount of Outstanding 2020 Debentures represented 2 6 thereby shall be made by the Securities Custodian in accordance with the standing instructions and procedures existing between the Depositary and the Securities Custodian. Members of, or participants in, the Depositary ("Agent Members") shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (B) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any 2020 Debenture. (c) Certificated Securities. Certificated Securities shall be issued only under the limited circumstances provided in Section 102(a)(1) hereof. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Securities. The Company initially appoints the Trustee to act as Paying Agent and Conversion Agent with respect to the 2020 Debentures. SECTION 102 Transfer and Exchange. (a) Transfer and Exchange of Global Securities. (1) 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. Only Restricted Certificated Securities shall be issued in exchange for beneficial interests in Restricted Global Securities, and only Unrestricted Certificated Securities shall be issued in exchange for beneficial interests in Unrestricted Global Securities. 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 3 7 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. (2) Notwithstanding any other provisions of this Indenture other than the provisions set forth in Section 102(a)(1) hereof, a Global Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. (b) Transfer and Exchange of Certificated Securities. When Certificated Securities are presented by a Holder to a Registrar with a request: (1) to register the transfer of the Certificated Securities to a person who will take delivery thereof in the form of Certificated Securities only; or (2) to exchange such Certificated Securities for an equal Principal Amount of Certificated Securities of other authorized denominations, such Registrar shall register the transfer or make the exchange as requested; provided, however, that the Certificated Securities presented or surrendered for register of transfer or exchange: (1) shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the fifth paragraph of Section 305 of the Indenture; and (2) in the case of a Restricted Certificated Security, such request shall be accompanied by the following additional information and documents, as applicable: (A) if such Restricted Certificated Security is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, or such Restricted Certificated Security is being transferred to the Company or a Subsidiary of the Company, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate required pursuant to Section 102(e)(1) hereof); (B) if such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB in accordance with Rule 144A or 4 8 pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or (C) if such Restricted Certificated Security is being transferred (i) pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144 or (ii) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A or Rule 144) and as a result of which, in the case of a Security transferred pursuant to this clause (ii), such Security shall cease to be a "restricted security" within the meaning of Rule 144, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or such Registrar so requests, a customary opinion of counsel, certificates and other information reasonably acceptable to the Company and such Registrar to the effect that such transfer is in compliance with the Securities Act. (c) Transfer of a Beneficial Interest in a Restricted Global Security for a Beneficial Interest in an Unrestricted Global Security. Any person having a beneficial interest in a Restricted Global Security may upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of an Unrestricted Global Security. Upon receipt by the Trustee of written instructions or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Security and the following additional information and documents in such form as is customary for the Depositary from the Depositary or its nominee on behalf of the person having such beneficial interest in the Restricted Global Security (all of which may be submitted by facsimile or electronically): (1) if such beneficial interest is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from the transferor (in substantially the form set forth in the Transfer Certificate); or (2) if such beneficial interest is being transferred (i) pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144 or (ii) pursuant to an exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A or Rule 144) and as a result of which, in the case of a Security transferred pursuant to this clause (ii), such Security shall cease to be a "restricted security" within the meaning of Rule 144, a certification to that effect from the transferor (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Trustee so requests, a customary opinion of counsel, certificates and other information reasonably acceptable to the Company and the Trustee to the effect that such transfer is in compliance with the Securities Act, 5 9 the Trustee, as a Registrar and Securities Custodian, shall reduce or cause to be reduced the aggregate Principal Amount of the Restricted Global Security by the appropriate Principal Amount and shall increase or cause to be increased the aggregate Principal Amount of the Unrestricted Global Security by a like Principal Amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Unrestricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver an Unrestricted Global Security. (d) Transfers of Certificated Securities for Beneficial Interest in Global Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities and, thereafter, the events or conditions specified in Section 102(a)(1) hereof 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.

If such an agreement is entered into, any 2020 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 11:00 A.M. New York City time on the Redemption Date, subject to payment of the above amount as aforesaid. The Paying Agent shall hold and pay to the Holders whose 2020 Debentures are selected for redemption any such amount paid to it for purchase in the same manner as it would money deposited 27 31 with it by the Company for the redemption of 2020 Debentures. Without the Paying Agent's prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any 2020 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 2020 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, Tax Event, Repurchase. The Indenture is hereby amended, subject to Section 201 hereof and with respect to the 2020 Debentures only, by adding the following Articles Fourteen, Fifteen, Sixteen and Seventeen to the Indenture: ARTICLE FOURTEEN CONVERSION SECTION 1401 Conversion Privilege. 2020 Debentures shall be convertible in accordance with their terms and in accordance with this Article. A Holder of a 2020 Debenture may convert the Principal Amount of such 2020 Debenture (or any portion thereof equal to a Principal Amount of $1,000 or any integral multiple of a Principal Amount of $1,000 in excess thereof) into Common Stock at any time prior to the close of business on the date specified in the 2020 Debentures, at the Conversion Rate then in effect. In case a 2020 Debenture or portion thereof is called for redemption pursuant to Article Eleven, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Redemption Date for such 2020 Debenture or such earlier date as the Holder presents such 2020 Debenture for redemption (unless the Company shall default in making the redemption payment when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such 2020 Debenture is redeemed). The number of shares of Common Stock issuable upon conversion of a 2020 Debenture per $1,000 of 28 32 Principal Amount thereof (the "Conversion Rate") shall be that set forth under "Conversion" in the 2020 Debentures, subject to adjustment as herein set forth. Provisions of this Indenture that apply to conversion of all of a 2020 Debenture also apply to conversion of a portion of a 2020 Debenture. A 2020 Debenture in respect of which a Holder has delivered a Repurchase Notice or Change in Control Purchase Notice exercising the option of such Holder to require the Company to purchase such 2020 Debenture, may be converted only if such notice of exercise is withdrawn in accordance with the terms of this Indenture. A Holder of 2020 Debentures is not entitled to any rights of a holder of Common Stock until such Holder has converted its 2020 Debentures to Common Stock, and only to the extent such 2020 Debentures are deemed to have been converted into Common Stock pursuant to this Article Fourteen. SECTION 1402 Conversion Procedure. To convert a 2020 Debenture, a Holder must (a) complete and manually sign the conversion notice on the back of the 2020 Debenture and deliver such notice to a Conversion Agent, (b) surrender the 2020 Debenture to a Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by the Security Registrar or a Conversion Agent, and (d) pay any transfer or similar tax, if required. The date on which the Holder satisfies all of those requirements is the "Conversion Date" As soon as practicable after the Conversion Date, the Company shall deliver to the Holder through a Conversion Agent a certificate for the number of whole shares of Common Stock issuable upon the conversion and cash in lieu of any fractional shares pursuant to Section 1403. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such 2020 Debentures may be surrendered for conversion in accordance with the applicable procedures 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 2020 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 to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided further, however, that such conversion shall be at the Conversion Rate in effect on the date that such 2020 Debenture shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. 29 33 Upon conversion of a 2020 Debenture, such Person shall no longer be a Holder of such 2020 Debenture. No payment or adjustment will be made for dividends on, or other distributions with respect to, any Common Stock except as provided in this Article Fourteen. On conversion of a 2020 Debenture, that portion of accrued Original Issue Discount (and interest, if the Company has exercised its option provided for in Section 1601) attributable to the period from the Issue Date (or, in the case of interest, if the Company has exercised the option provided for in Section 1601, the later of (x) the date of such exercise and (y) the date on which interest was last paid) of the 2020 Debenture through the Conversion Date with respect to the converted 2020 Debenture shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the 2020 Debenture being converted pursuant to the provisions hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall be treated as issued, to the extent thereof, first in exchange for Original Issue Discount (and interest, if the Company has exercised its option provided for in Section 1601) accrued through the Conversion Date, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the 2020 Debenture being converted pursuant to the provisions hereof. If a Holder converts more than one 2020 Debenture at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the aggregate Principal Amount of 2020 Debentures converted. Upon surrender of a 2020 Debenture that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new 2020 Debenture equal in Principal Amount to the Principal Amount of the unconverted portion of the 2020 Debenture surrendered. Where the Company has exercised its option under Section 1701, 2020 Debentures or portions thereof surrendered for conversion during the period from the close of business on any Regular Record Date immediately preceding any Interest Payment Date to the opening of business on such Interest Payment Date shall (unless such 2020 Debentures or portions thereof have been called for redemption on a Redemption Date within such period) be accompanied by payment to the Company or its order, in New York Clearing House funds or other funds acceptable to the Company, of an amount equal to the interest payable on such Interest Payment Date on the principal amount of 2020 Debentures or portions thereof being surrendered for conversion. 30 34 SECTION 1403 Fractional Shares. The Company will not issue fractional shares of Common Stock upon conversion of 2020 Debentures. In lieu thereof, the Company will pay an amount in cash based upon the closing price of the Common Stock on the Trading Day immediately prior to the Conversion Date. SECTION 1404 Taxes on Conversion. If a Holder converts a 2020 Debenture, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. The Conversion Agent may refuse to deliver the certificate representing the Common Stock being issued in a name other than the Holder's name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude any tax withholding required by law or regulation. SECTION 1405 Company to Provide Common Stock. The Company shall, prior to issuance of any 2020 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 2020 Debentures Outstanding into shares of Common Stock. All shares of Common Stock delivered upon conversion of the 2020 Debentures shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any Lien or adverse claim. The Company will endeavor promptly to comply with all federal and state securities laws regulating the registration of the offer and delivery of shares of Common Stock to a converting Holder upon conversion of 2020 Debentures, if any, and will list or cause to have quoted such shares of Common Stock on each national securities exchange or on the Nasdaq National Market or other over-the-counter market or such other market on which the 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: 31 35 (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 2020 Debenture thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have owned had such 2020 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 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 32 36 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 or of such rights or warrants applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the record date). Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately 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 2020 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 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 33 37 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 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 34 38 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 Ordinary Share (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 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 35 39 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. (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 36 40 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 an Ordinary Share 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 2020 Debenture converted after such record date or Determination Date or Expiration Date the shares of Common Stock and other capital stock of the Company issuable upon such conversion over and above the shares of Common Stock and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Rate is required to be made as of the record date or Determination Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect if such record date had not been fixed or such effective date or Determination Date or Expiration Date had not occurred. 37 41 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 2020 Debentures become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. SECTION 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 38 42 (3) there is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice at least 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 2020 Debentures (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination); (b) any consolidation or merger in which the Company is a party consolidating with another entity or merging with or into another entity other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, Outstanding shares of Common Stock; or (c) any sale or conveyance of all or substantially all of the property and assets of the Company to any Person, then the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, change, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each 2020 Debenture then Outstanding shall have the right to convert such 2020 Debenture into the kind and amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock deliverable upon conversion of such 2020 Debenture immediately prior to such reclassification, change, consolidation, merger, sale or conveyance. 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 2020 Debentures as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The 39 43 provisions of this Section 1411 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales or conveyances. 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 2020 Debentures upon the conversion of their 2020 Debentures after any such reclassification, change, consolidation, merger, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and (y) an Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. SECTION 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 2020 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. 40 44 ARTICLE FIFTEEN REPURCHASE OF SECURITIES AT OPTION OF THE HOLDER SECTION 1501 General. The Company may be required to repurchase 2020 Debentures in accordance with their terms and in accordance with this Article. 2020 Debentures shall be purchased by the Company under the paragraph "Repurchase by the Company at the Option of the Holder" of the 2020 Debentures on June 6, 2005, June 6, 2010 and June 6, 2015 (each, a "Repurchase Date"), at the repurchase price specified therein (each, a "Repurchase Price"), at the option of the Holder thereof, upon: (1) delivery to the Paying Agent, by the Holder of a written notice of purchase (a "Repurchase Notice") at any time from the opening of business on the date that is 20 Business Days prior to a Repurchase Date until the close of business on such Repurchase Date stating: (A) the certificate number of the 2020 Debenture which the Holder will deliver to be repurchased, (B) the portion of the Principal Amount of the 2020 Debenture which the Holder will deliver to be repurchased, which portion must be $1,000 or an integral multiple thereof, (C) that such 2020 Debenture shall be purchased as of the Repurchase Date pursuant to the terms and conditions specified under the paragraph "Repurchase by the Company at the Option of the Holder" of the 2020 Debentures and in this Indenture, (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 2020 Debentures to which such Repurchase Notice relates (stating the Principal Amount at Maturity and certificate numbers of the 2020 Debentures as to which such withdrawal shall relate), or (ii) to receive cash in respect of the entire Repurchase Price for all 2020 Debentures (or portions thereof) to which such Repurchase Price relates, and 41 45 (2) delivery of such 2020 Debenture to the Paying Agent prior to, on or after the Repurchase Date (together with all necessary endorsements) at the offices of the Paying Agent, such delivery being a condition to receipt by the Holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Article Fifteen only if the 2020 Debenture so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice. 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 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 2020 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 2020 Debenture if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a 2020 Debenture also apply to the purchase of such portion of such 2020 Debenture. Any purchase by the Company contemplated pursuant to the provisions of this Article Fifteen shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Repurchase Date and the time of delivery of the 2020 Debenture. Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 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 2020 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 42 46 shall designate, in the Company Notice delivered pursuant to Section 1505 hereof, whether the Company will purchase the 2020 Debentures for cash or Common Stock, or, if a combination thereof, the percentages of the Repurchase Price of 2020 Debentures in respect of which it will pay in cash and Common Stock; provided, however, that the Company will pay cash for fractional interests in Common Stock. For purposes of determining the existence of potential fractional interests, all 2020 Debentures subject to purchase by the Company held by a Holder shall be considered together (no matter how many separate certificates are to be presented). Each Holder whose 2020 Debentures are purchased pursuant to this Article Fifteen shall receive the same percentage of cash or Common Stock in payment of the Repurchase Price for such 2020 Debentures, except (i) as provided in Section 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 2020 Debentures of a Holder or Holders for Common Stock because any necessary qualifications or registrations of the Common Stock under applicable state securities laws cannot be obtained, the Company may purchase the 2020 Debentures of such Holder or Holders for cash. The Company may not change its election with respect to the consideration (or components or percentages of components thereof) to be paid once the Company has given its Company Notice to Holders except pursuant to this Section 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 2020 Debentures in respect of which a Repurchase Notice pursuant to Section 1501 has been given, or a specified percentage thereof, may be paid by 43 47 the Company with cash equal to the aggregate Repurchase Price of such 2020 Debentures. If the Company elects to purchase 2020 Debentures with cash, the Company Notice, as provided in Section 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 2020 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 percentage, as the case may be, of the Repurchase Price of such 2020 Debentures in cash by (ii) the Market Price of a share of Common Stock, subject to the next succeeding paragraph. The Company will not issue a fractional share of Common Stock in payment of the Repurchase Price. Instead the Company will pay cash for the current market value of the fractional share. The current market value of a fraction of a share of Common Stock shall be determined by multiplying the Market Price by such fraction and rounding the product to the nearest whole cent with one half cent being rounded upwards. It is understood that if a Holder elects to have more than one 2020 Debenture repurchased, the number of shares of Common Stock shall be based on the aggregate amount of 2020 Debentures to be repurchased. If the Company elects to purchase the 2020 Debentures by the issuance of Common Stock, the Company Notice, as provided in Section 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 2020 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 2020 Debentures with Common Stock as provided herein; 44 48 (ii) the registration of the Common Stock to be issued in respect of the payment of the Repurchase Price under the Securities Act or the Exchange Act, in each case, if required for the initial issuance thereof; (iii) any necessary qualification or registration under applicable state securities laws or the availability of an exemption from such qualification and registration; and (iv) the receipt by the Trustee of an Officers' Certificate and an Opinion of Counsel each stating that (A) the terms of the issuance of the Common Stock are in conformity with this Indenture and (B) the Common Stock to be issued by the Company in payment of the Repurchase Price in respect of 2020 Debentures have been duly authorized and, when issued and delivered pursuant to the terms of this Indenture in payment of the Repurchase Price in respect of the 2020 Debentures, will be validly issued, fully paid and 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) and (iii) above and the condition set forth in the second succeeding sentence have been satisfied and, in the case of such Opinion of Counsel, stating that conditions (ii) and (iii) above have been satisfied. Such Officers' Certificate shall also set forth the number of shares of Common Stock to be issued for each $1,000 Principal Amount of 2020 Debentures and the Sale Price of a share of Common Stock on each trading day during the period commencing on the first trading day of the period during which the Market Price is calculated and ending three Business Days prior to the applicable Repurchase Date. The Company may pay the Repurchase Price (or any portion thereof) in Common Stock only if the 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 2020 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 2020 Debentures of such Holder or Holders in cash. The "Market Price" means the average of the Sale Prices of the Common Stock for the five trading day period ending on (if the third Business Day prior to the applicable Repurchase Date is a trading day, or if not, then on the last trading day prior to), the third Business Day prior to the applicable Repurchase Date appropriately adjusted to take into account the occurrence, during the period commencing on the first of such trading days during such five trading day period 45 49 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 its successors. 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 2020 Debentures held by such Holder (except any cash amount to be paid in lieu of fractional shares); (2) set forth the method of calculating the Market Price of the Common Stock; and (3) state that because the Market Price of Common Stock will be determined prior to the Repurchase Date, Holders will bear the market risk with respect to the value of the Common Stock to be received from the date such Market Price is determined to the Repurchase Date. In any case, each Company Notice shall include a form of Repurchase Notice to be completed by a Holder and shall state: (A) the Repurchase Price and the Conversion Rate; (B) the name and address of the Paying Agent and the Conversion Agent; 46 50 (C) that 2020 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 2020 Debentures must be surrendered to the Paying Agent to collect payment; (E) that the Repurchase Price for any 2020 Debenture as to which a Repurchase Notice has been given and not withdrawn will be paid promptly following the later of the Repurchase Date and the time of surrender of such 2020 Debenture as described in (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 2020 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). 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 2020 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 2020 Debentures shall be newly issued shares or treasury shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. The Company shall use its reasonable efforts to list or cause to have quoted any Common Stock to be issued to purchase 2020 Debentures on the principal national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 47 51 SECTION 1507 Procedure upon Repurchase. The Company shall deposit cash (in respect of a cash purchase under Section 1503 or for fractional Common Stock, 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 all 2020 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 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 2020 Debenture is paid in Common Stock, the Company shall pay any documentary, stamp or similar issue or transfer tax due on such issue of Common Stock. However, the Holder shall pay any such tax which is due because the Holder requests the Common Stock to be issued in a name other than the Holder's name. The Paying Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder's name until the Paying Agent receives a sum sufficient to pay any tax which will be due because the shares of Common Stock are to be issued in a name other than the Holder's name. SECTION 1509 Effect of Repurchase Notice. Upon receipt by the Paying Agent of the Repurchase Notice, the Holder of the 2020 Debenture in respect of which such Repurchase Notice was given shall (unless such Repurchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Repurchase Price with respect to such 2020 Debenture. Such Repurchase Price shall be paid to such Holder, subject to receipt of funds and/or Common Stock by the Paying Agent, promptly following the later of (x) the Repurchase Date with respect to such 2020 Debenture (provided the conditions in Section 1501 have been satisfied) and (y) the time of delivery of such 2020 Debenture to the Paying Agent by the Holder thereof in the manner required by Section 1501. 2020 Debentures in respect of 48 52 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 2020 Debenture in respect of which such notice of withdrawal is being submitted; (2) the Principal Amount of the 2020 Debenture with respect to which such notice of withdrawal is being submitted; and (3) the Principal Amount, if any, of such 2020 Debenture which remains subject to the original Repurchase Notice and which has been or will be delivered for purchase by the Company. A written notice of withdrawal of a Repurchase Notice may be in the form set forth in the preceding paragraph or may be in the form of (i) a conditional withdrawal contained in a Repurchase Notice pursuant to the terms of Section 1501(1)(D) or (ii) a conditional withdrawal containing the information set forth in Section 1501(1)(D) and the preceding paragraph and contained in a written notice of withdrawal delivered to the Paying Agent as set forth in the preceding paragraph. There shall be no purchase of any 2020 Debentures pursuant to this Article 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 2020 Debentures, of the required Repurchase Notice) and is continuing an Event of Default (other than a default in the payment of the Repurchase Price with respect to such 2020 Debentures). The Paying Agent will promptly return to the respective Holders thereof any 2020 Debentures (x) with respect to which a Repurchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Repurchase Price with respect to such 2020 Debentures) in which case, upon such return, the Repurchase Notice with respect thereto shall be deemed to have been withdrawn. 49 53 SECTION 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 all of the 2020 Debentures or portions thereof which are to be purchased as of the Repurchase Date. SECTION 1511 Securities Repurchased in Part. Any 2020 Debenture which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company or the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such 2020 Debenture, without service charge, a new 2020 Debenture or 2020 Debentures, of any authorized denomination as requested by such Holder in aggregate Principal Amount equal to, and in exchange for, the portion of the Principal Amount of the 2020 Debenture so surrendered which is not purchased. SECTION 1512 Comply with Securities Laws Upon Purchase of Securities. In connection with any offer to purchase or purchase of 2020 Debentures under this Article Fifteen (provided that such offer or purchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply with Rule 13e-4 under the Exchange Act, (ii) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, and (iii) otherwise comply with all Federal and state securities laws so as to permit the rights and obligations under Article Fifteen to be exercised in the time and in the manner specified in this Article Fifteen. SECTION 1513 Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash or Common Stock that remain unclaimed for two years, subject to applicable unclaimed property law, together with interest or dividends, if any, thereon held by them for the payment of the Repurchase Price; provided, however, that to the extent that the aggregate amount of cash or Common Stock deposited by the Company pursuant to Section 1510 exceeds the aggregate Repurchase Price of the 50 54 2020 Debentures or portions thereof which the Company is obligated to purchase as of the Repurchase Date, then promptly after the Business Day following the Repurchase Date the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon. After that, Holders entitled to money must look to the Company for payment as general creditors, unless an applicable abandoned property law designates another Person. SECTION 1514 Conversion Arrangement on Repurchase. Any Securities required to be repurchased under this Article Fifteen, unless surrendered for conversion before the close of business on the Repurchase Date, may be deemed to be purchased from the Holders of such Securities for an amount in cash not less than the Repurchase Price, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Trustee in trust for such Holders. 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 2020 Debentures remain Outstanding there shall occur a Change in Control, 2020 Debentures shall be purchased by the Company at the option of the Holders thereof as of the date that is 35 Business Days after the occurrence of the Change in Control (the "Change in Control Purchase Date") at a purchase price equal to the Issue Price plus accrued Original Issue Discount through the Change in Control Purchase Date (or, if the option under Section 1701 has been exercised, the Restated Principal Amount plus accrued and unpaid interest from the Option Exercise Date to the Change in Control Purchase Date) (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.

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; 52 56 (3) the Change in Control Purchase Date; (4) the Change in Control Purchase Price; (5) briefly, the conversion rights of the 2020 Debentures; (6) the name and address of each Paying Agent and Conversion Agent; (7) the Conversion Rate and any adjustments thereto; (8) that 2020 Debentures as to which a 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 2020 Debentures in order to convert the Securities.

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 2020 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 l601(c), the Holder of the 2020 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 with respect to such 2020 Debenture.

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 any 2020 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 2020 Debenture will cease to be Outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Change in Control Purchase Price as aforesaid). The Company shall publicly announce the Principal Amount of 2020 Debentures purchased as a result of such Change in Control on or as soon as practicable after the Change in Control Purchase Date.

SECTION 1605 Compliance With Securities Laws Upon Purchase of Securities. In connection with any offer to purchase or purchase of 2020 Debentures under Section 1601, the Company shall (a) comply with Rule 13e-4 (or any successor to either such Rule), if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer, all so as to permit the rights of the Holders and obligations of the Company under Sections 1601 through 1606 to be exercised in the time and in the manner specified therein. SECTION 1606 Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 1603 exceeds the aggregate Change in Control Purchase Price together with interest, if any, thereon of the 2020 Debentures or portions thereof that the Company is obligated to purchase, then promptly after the Change in Control Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess to the Company.

Within 15 days of the occurrence of a Tax Event, the Company 56 60 shall mail a written notice of such Tax Event by first-class mail to the Trustee and within 15 days of its exercise of such option the Company shall mail a written notice of the Option Exercise Date by first-class mail to the Trustee and Holders of the 2020 Debentures. From and after the Option Exercise Date, (i) the Company shall be obligated to pay at Stated Maturity, in lieu of the Principal Amount of a Security, the Restated Principal Amount thereof and (ii) "Issue Price and accrued Original Issue Discount," "Issue Price plus Original Issue Discount" or similar words, as used herein, shall mean Restated Principal Amount plus accrued and unpaid interest with respect to any 2020 Debenture. 2020 Debentures authenticated and delivered after the Option Exercise Date may, and shall if required by the Trustee, bear a notation in a form approved by the Trustee as to the conversion of the 2020 Debentures to interest-bearing 2020 Debentures.

ZERO COUPON CONVERTIBLE DEBENTURE DUE JUNE 6, 2020 This Security is one of a duly authorized issue of senior securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of February 4, 1997, as amended by the Second Supplemental Indenture thereto, dated as of June 6, 2000 (as so amended, herein called the "Indenture"), between the Company and The Chase Manhattan Bank, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount at maturity to $805,000,000. INTEREST This Security shall not bear interest, except as specified in this paragraph or as described under "Tax Event". If the Principal Amount hereof or any portion of such Principal Amount is not paid when due (whether upon acceleration pursuant to Section 502 of the Indenture, upon the date set for payment of the Redemption Price as described under "Optional Redemption", upon the date set for payment of the Change in Control Purchase Price pursuant to "Purchase of Securities 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 Security) or if interest due hereon, if any (or any portion of such interest), is not paid when due, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate of 3.5% per annum, compounded semi-annually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable as set forth in the Indenture. The accrual of such interest on overdue amounts shall be in lieu of, and not in addition to, the continued accrual of Original Issue Discount. Original Issue Discount (the difference between the Issue Price and the Principal Amount of the Security), in the period during which a Security remains outstanding, shall accrue at 3.5% per annum, on a semiannual bond equivalent basis using a 360-day year composed of twelve 30-day months, from the Issue Date of this Security. METHOD OF PAYMENT Payments in respect of principal of and interest, if any, on the Securities shall be made by the Company in immediately available funds. A-6 71 OPTIONAL REDEMPTION No sinking fund is provided for the Securities. The Securities are redeemable as a whole, or from time to time in part, at any time at the option of the Company at the Redemption Price set forth below, after June 6, 2005.

If converted to an interest-bearing debenture following the occurrence of a Tax Event, this Security will be redeemable at the Restated Principal Amount plus accrued and unpaid interest from the date of such conversion to the Redemption Date; but in no event will this Security be redeemable before June 6, 2005. If the Company redeems less than all of the outstanding Securities, the Trustee will select the Securities to be redeemed (i) by lot; (ii) pro rata; or (iii) by another method the Trustee considers fair and appropriate. If the Trustee selects a portion of a Holder's Securities for partial redemption and the Holder converts a portion of the same Securities, the converted portion will be deemed to be from the portion selected for redemption. A-7 72 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 Securities to be redeemed at its registered address. Securities in denominations larger than $1,000 Principal Amount may be redeemed in part, but only in whole multiples of $1,000. On and after the Redemption Date, subject to the deposit with the Paying Agent of funds sufficient to pay the Redemption Price, Original Issue Discount (or interest, if the Security is converted to an interest-bearing debenture) ceases to accrue on Securities or portions thereof called for redemption. PURCHASE OF SECURITIES AT OPTION OF HOLDER UPON A 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 Securities 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 Issue Price plus accrued Original Issue Discount through 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. If prior to a Change in Control Purchase Date this Security has been converted to an interest-bearing debenture following the occurrence of a Tax Event, the Change in Control Purchase Price shall be equal to the Restated Principal Amount plus accrued and unpaid interest from the date of conversion to the Change in Control Purchase Date. CONVERSION A Holder of a Security may convert the Security into shares of Common Stock at any time until the close of business on the Business Day prior to the Stated Maturity; provided, however, that if the Security is called for redemption, the conversion right will terminate at the close of business on the Business Day immediately preceding the Redemption Date for such Security or such earlier date as the Holder presents such Security for redemption (unless the Company shall default in making the redemption payment when due, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Security is redeemed). A Security in respect of which a Holder has delivered a Repurchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if such notice of exercise is withdrawn in accordance with the terms of the Indenture. The initial Conversion Rate is 8.6075 shares of Common Stock per $1,000 Principal Amount, subject to adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock. A-8 73 In the event the Company exercises its option pursuant to Section 1701 of the Indenture to have interest in lieu of Original Issue Discount accrue on the Security following a Tax Event, the Holder will be entitled on conversion to receive the same number of shares of Common Stock such Holder would have received if the Company had not exercised such option. If the Company exercises such option, Securities surrendered for conversion during the period from the close of business on any Regular Record Date immediately preceding any Interest Payment Date to the opening of business of such Interest Payment Date (except Securities or portions of Securities to be redeemed on a Redemption Date occurring during the period from the close of business on a Regular Record Date and ending on the opening of business on the first Business Day after the next Interest Payment Date, or if this Interest Payment Date is not a Business Day, the second Business Day after the Interest Payment Date) must be accompanied by payment from the Holder of an amount equal to the interest thereon that the registered Holder is to receive from the Company on such Interest Payment Date. Except where Securities surrendered for conversion must be accompanied by payment as described above, no interest on converted Securities will be payable by the Company on any Interest Payment Date subsequent to the date of conversion. A Holder may convert a portion of a Security if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000. No payment or adjustment will be made for dividends on the Common Stock except as provided in the Indenture. On conversion of a Security, that portion of accrued Original Issue Discount (and interest if the Security is converted to an interest-bearing debenture) attributable to the period from the Issue Date (or, in the case of interest, if the Company has exercised the option referred to in "Tax Event", the later of (x) the date of such exercise and (y) the date on which interest was last paid) through the Conversion Date with respect to the converted Security shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the Holder thereof through the delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares) in exchange for the Security being converted pursuant to the terms hereof; and the fair market value of such shares of Common Stock (together with any such cash payment in lieu of fractional shares) shall be treated as issued, to the extent thereof, first in exchange for Original Issue Discount (and interest, if the Company has exercised its option provided for in "Tax Event") accrued through the Conversion Date, and the balance, if any, of such fair market value of such Common Stock (and any such cash payment) shall be treated as issued in exchange for the Issue Price of the Security being converted pursuant to the provisions hereof. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the closing price of the Common Stock on the Trading Day immediately prior to the Conversion Date. To convert a Security, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Security to the 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. A-9 74 REPURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the Holder, the Securities held by such Holder on the following Repurchase Dates and at the following Repurchase Prices per $1,000 Principal Amount, upon delivery of a Repurchase Notice containing the information set forth in the Indenture, at any time from the opening of business on the date that is 20 Business Days prior to such Repurchase Date until the close of business on such Repurchase Date and upon delivery of the Securities to the Paying Agent by the Holder as set forth in the Indenture.
REPURCHASE REPURCHASE DATE PRICE ---------- ---------- June 6, 2005........... $ 594.25 June 6, 2010........... $ 706.82 June 6, 2015........... $ 840.73
The Repurchase Price (equal to the Issue Price plus accrued Original Issue Discount through the Repurchase Date) may be paid, at the option of the Company, in cash or by the issuance of Common Stock (as provided in the Indenture), or in any combination thereof. If prior to a Repurchase Date this Security has been converted to an interest-bearing debenture following the occurrence of a Tax Event, the Repurchase Price will be equal to the Restated Principal Amount plus accrued and unpaid interest from the date of conversion to the Repurchase Date. Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a written notice of withdrawal prior to the close of business on the Repurchase Date in accordance with the provisions of the Indenture. If cash (and/or securities if permitted under the Indenture) sufficient to pay the Repurchase Price of all Securities or portions thereof to be purchased as of the Repurchase Date, is deposited with the Paying Agent on the Business Day following the Repurchase Date, Original Issue Discount (or interest, if this Security has been converted to an interest-bearing debenture following the occurrence of a Tax Event) ceases to accrue on such Securities (or portions thereof) immediately after such Repurchase Date, and the Holder thereof shall have no other rights as such (other than the right to receive the Repurchase Price upon surrender of such Security). TAX EVENT From and after (i) the date (the "Tax Event Date") of the occurrence of a Tax Event and (ii) the date the Company exercises such option, whichever is later (the "Option Exercise Date"), at the option of the Company, interest in lieu of future Original Issue Discount shall accrue at the rate of 3.5% per annum on a Principal Amount per Security (the "Restated Principal Amount") equal to the A-10 75 Issue Price plus Original Issue Discount accrued through the Option Exercise Date and shall be payable semiannually on June 6 and December 6 of each year (each an "Interest Payment Date") to holders of record at the close of business on May 23 or November 22 (each a "Regular Record Date") immediately preceding such Interest Payment Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months and will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Option Exercise Date. Interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. Each installment of interest on any Security shall be paid in same-day funds by transfer to an account maintained by the payee located inside the United States. Except as otherwise specified with respect to the Securities, any Defaulted Interest on any Security shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 307 of the Indenture. CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION Any Securities called for redemption, unless surrendered for conversion before the close of business on the Redemption Date, may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Paying Agent in trust for such Holders. TRANSFER As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration or transfer at the office or agency in a Place of Payment for Securities of this series, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of any authorized denominations and for the same aggregate principal amount, executed by the Company and authenticated and delivered by the Trustee, will be issued to the designated transferee or transferees. The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof.
