provided that (i) such mortgage, pledge, security interest, lien or encumbrance existed at the time such Person became a Significant Subsidiary and was not created in anticipation of the acquisition, and (ii) any such mortgage, pledge, security interest, lien or encumbrance does not by its terms secure any Indebtedness other than Indebtedness existing or committed immediately prior to the time such Person becomes a Significant Subsidiary;

ARTICLE IV Optional Redemption of the Notes Section 401 Right to Redeem; Notice to Trustee, Paying Agent and Holders. On or after May 15, 2008, the Company may, at its option, redeem the Notes in whole, or in part, at any time in accordance with the provisions of paragraph 6 of the Notes. If the Company elects to redeem Notes pursuant to paragraph 6 of the Notes, it shall notify in writing the Trustee, the Paying Agent and each Holder of Notes to be redeemed, as provided in Section 1104 of the Indenture and Section 404 hereof. Section 402 Fewer Than All Outstanding Notes to Be Redeemed. If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes to be redeemed in 14 principal amounts of $1,000 or integral multiples thereof. In the case that the Trustee shall select the Notes to be redeemed, the Trustee may effectuate such selection by lot, pro rata, or by any other method that the Trustee considers fair and appropriate. The Trustee will make such selection promptly following receipt of the notice of redemption from the Company provided pursuant to Section 404 hereof. Section 403 Selection of Notes to Be Redeemed. If any Notes selected for partial redemption are thereafter surrendered for conversion in part before termination of the conversion right with respect to the portion of the Notes so selected, the converted portion of such Notes shall be deemed (so far as may be), solely for purposes of determining the aggregate principal amount of Notes to be redeemed by the Company, to be the portion selected for redemption. Notes which have been converted during a selection of Notes to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. Nothing in this Section 403 shall affect the right of any Holder to convert any Notes pursuant to Article VIII hereof before the termination of the conversion right with respect thereto. Section 404 Notice of Redemption. In addition to those matters set forth in Section 1104 of the Indenture, a notice of redemption sent to Holders of Notes shall state: (a) the then current Conversion Rate; (b) the name and address of the Paying Agent and the Conversion Agent; (c) that the Notes called for redemption may be converted at any time before the close of business on the Business Day immediately preceding the Redemption Date; and (d) that Holders who wish to convert Notes must comply with the procedures in paragraph 10 of the Notes. Section 405 Effect of Notice of Redemption. Once notice of redemption is mailed, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price, except for Notes that are converted in accordance with the provisions of Article VIII hereof and paragraph 10 of the Notes. Upon presentation and surrender to the Paying Agent, Notes called for redemption shall be paid at the Redemption Price as defined in paragraph 6 of the Notes. Section 406 Deposit of Redemption Price. On or before 10:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) an amount of money sufficient to pay the aggregate Redemption Price of all the Notes to be redeemed on that date other than the Notes or portions thereof called for redemption which on or prior thereto have been delivered by the Company to the Security Registrar for cancellation or have been converted. The Trustee and Paying Agent shall, as promptly as practicable, return to the Company any money not required for that purpose because of conversion of the Notes in accordance with the provisions of Article VIII hereof. If such money is then held by the Company or a Subsidiary in trust and is not required for such purpose, it shall be discharged from such trust. 15 ARTICLE V Purchase Upon a Fundamental Change Section 501 Purchase at the Option of the Holder Upon a Fundamental Change. If a Fundamental Change shall occur at any time prior to May 15, 2008, each Holder shall have the right, at such Holder's option, to require the Company to purchase any or all of such Holder's Notes for cash on the date that is no later than 35 days after the date of the Company Notice of the occurrence of such Fundamental Change (subject to extension to comply with applicable law, as provided in Section 704) (the "Fundamental Change Purchase Date"). The Notes shall be repurchased in integral multiples of $1,000 of the principal amount. The Company shall purchase such Notes at a price (the "Fundamental Change Purchase Price") equal to 100% of the principal amount of the Notes to be purchased plus accrued and unpaid interest, including Contingent Interest and Additional Amounts, if any, to the Fundamental Change Purchase Date. No Notes may be purchased at the option of the Holders upon a Fundamental Change if there has occurred and is continuing an Event of Default (other than an Event of Default that is cured by the payment of the Fundamental Change Purchase Price of the Notes). Section 502 Notice of Fundamental Change. The Company, or at its request (which must be received by the Paying Agent at least three Business Days (or such lesser period as agreed to by the Paying Agent) prior to the date the Paying Agent is requested to give such notice as described below), the Paying Agent in the name of and at the expense of the Company, shall mail to all Holders and the Trustee and the Paying Agent a Company Notice of the occurrence of a Fundamental Change and of the purchase right arising as a result thereof, including the information required by Section 701 hereof, on or before the 30th day after the occurrence of such Fundamental Change. Section 503 Exercise of Option. For a Note to be so purchased at the option of the Holder, the Paying Agent must receive such Note duly endorsed for transfer, together with a written notice of purchase (a "Fundamental Change Purchase Notice") and the form entitled "Form of Fundamental Change Purchase Notice" on the reverse thereof duly completed, on or before the 35th day after the date of the Company Notice of the occurrence of such Fundamental Change, subject to extension to comply with applicable law. The Fundamental Change Purchase Notice shall state: (a) if certificated, the certificate numbers of the Notes which the Holder shall deliver to be purchased, or, if not certificated, the Fundamental Change Purchase Notice must comply with appropriate Depositary procedures; (b) the portion of the principal amount of the Notes which the Holder shall deliver to be purchased, which portion must be $1,000 in principal amount or an integral multiple thereof; and (c) that such Notes shall be purchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions specified in paragraph 8 of the Notes and in this Supplemental Indenture. 16 Section 504 Procedures. The Company shall purchase from a Holder, pursuant to Article V hereof, Notes if the principal amount of such Notes is $1,000 or a multiple of $1,000 if so requested by such Holder. Any purchase by the Company contemplated pursuant to the provisions of Article V hereof shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the Holder promptly following the later of the Fundamental Change Purchase Date or the time of book-entry transfer or delivery of the Notes. Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by Section 503 shall have the right at any time prior to the close of business on the Business Day prior to the Fundamental Change Purchase Date to withdraw such Fundamental Change Purchase Notice (in whole or in part) by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 702. The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written notice of withdrawal thereof. On or before 10:00 a.m. (New York City time) on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) money sufficient to pay the aggregate Fundamental Change Purchase Price of the Notes to be purchased pursuant to Article V hereof. Payment by the Paying Agent of the Fundamental Change Purchase Price for such Notes shall be made promptly following the later of the Fundamental Change Purchase Date or the time of book-entry transfer or delivery of such Notes. If the Paying Agent holds, in accordance with the terms of the Indenture, money sufficient to pay the Fundamental Change Purchase Price of such Notes on the Business Day following the Fundamental Change Purchase Date, then, on and after such date, such Notes shall cease to be outstanding and interest (including Contingent Interest and Additional Amounts, if any) on such Notes shall cease to accrue, whether or not book-entry transfer of such Notes is made or such Notes are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery or transfer of the Notes). Nothing herein shall preclude any withholding tax required by law. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of the Fundamental Change Purchase Price and shall notify the Trustee of any default by the Company in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to deliver all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the cash delivered to the Trustee. 17 All questions as to the validity, eligibility (including time of receipt) and acceptance of any Notes for redemption shall be determined by the Company, whose determination shall be final and binding. ARTICLE VI Optional Purchase Section 601 Purchase of Notes by the Company at the Option of the Holder. (a) On each of May 15, 2008, May 15, 2013 and May 15, 2018 (each, a "Purchase Date"), Holders shall have the option to require the Company to purchase any Notes at the Purchase Price specified in paragraph 8 of the Notes, upon: (i) delivery to the Paying Agent by the Holder of a written notice of purchase (a "Purchase Notice") at any time from the opening of business on the date that is 20 Business Days prior to a Purchase Date until the close of business on the fifth Business Day prior to such Purchase Date, stating: (1) if certificated, the certificate numbers of the Notes which the Holder will deliver to be purchased, or, if not certificated, the Purchase Notice must comply with appropriate Depositary procedures; (2) the portion of the principal amount of the Notes which the Holder will deliver to be purchased, which portion must be $1,000 in principal amount or an integral multiple thereof; and (3) that such Notes shall be purchased as of the Purchase Date pursuant to the terms and conditions specified in paragraph 8 of the Notes and in this Supplemental Indenture; and (ii) delivery or book-entry transfer of such Notes to the Paying Agent prior to, on or after the Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent, such delivery or transfer being a condition to receipt by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this Section 601 only if the Notes so delivered or transferred to the Paying Agent shall conform in all respects to the description thereof in the related Purchase Notice. (b) The Company shall purchase from a Holder, pursuant to the terms of this Section 601, Notes if the principal amount of such Notes is $1,000 or a multiple of $1,000 if so requested by such Holder. (c) Any purchase by the Company contemplated pursuant to the provisions of this Section 601 shall be consummated by the delivery of the Purchase Price to be received by the Holder promptly following the later of the Purchase Date or the time of book-entry transfer or delivery of the Notes. 18 (d) Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this Section 601 shall have the right at any time prior to the close of business on the Business Day prior to the Purchase Date to withdraw such Purchase Notice (in whole or in part) by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 702. (e) The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof. (f) On or before 10:00 a.m. (New York City time) on the Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) money sufficient to pay the aggregate Purchase Price of the Notes to be purchased pursuant to this Section 601. Payment by the Paying Agent of the Purchase Price for such Notes shall be made promptly following the later of the Purchase Date or the time of book-entry transfer or delivery of such Notes. If the Paying Agent holds, in accordance with the terms of the Indenture, money sufficient to pay the Purchase Price of such Notes on the Business Day following the Purchase Date, then, on and after such date, such Notes shall cease to be outstanding and interest (including Contingent Interest and Additional Amounts, if any) on such Notes shall cease to accrue, whether or not book-entry transfer of such Notes is made or such Notes are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right to receive the Purchase Price upon delivery or transfer of the Notes). (g) The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of the Purchase Price and shall notify the Trustee of any default by the Company in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to deliver all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the cash delivered to the Trustee. ARTICLE VII Conditions and Procedures for Purchases at Option of Holders Section 701 Notice of Purchase Date or Fundamental Change. The Company shall send notices (each, a "Company Notice") to the Holders (and to beneficial owners as required by applicable law) at their addresses shown in the Security Register maintained by the Security Registrar, and delivered to the Trustee and Paying Agent, not less than 20 Business Days prior to each Purchase Date, or on or before the 30th day after the occurrence of the Fundamental Change, as the case may be (each such date of delivery, a "Company Notice Date").

At the Company's request, made at least five Business Days prior to the date upon which such notice is to be mailed, and at the Company's expense, the Paying Agent shall give the Company Notice in the Company's name; provided, however, that, in all cases, the text of the Company Notice shall be prepared by the Company. Section 702 Effect of Purchase Notice or Fundamental Change Purchase Notice; Effect of Event of Default. Upon receipt by the Company of the Purchase Notice or Fundamental Change Purchase Notice specified in Section 601 or Section 503, as applicable, the Holder of the Notes in respect of which such Purchase Notice or Fundamental Change Purchase Notice, as the case may be, was given shall (unless such Purchase Notice or Fundamental Change Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Purchase Price or Fundamental Change Purchase Price with respect to such Notes. Such Purchase Price or Fundamental Change Purchase Price shall be paid by the Paying Agent to such Holder promptly following the later of (x) the Purchase Date or the Fundamental Change Purchase Date, as the case may be, with respect to such Notes (provided the conditions in Section 601 or Section 503, as applicable, have been satisfied) and (y) the time of delivery or book-entry transfer of such Notes to the Paying Agent by the Holder thereof in the manner required by Section 601 or Section 503, as applicable. Notes in respect of which a Purchase Notice or Fundamental Change Purchase Notice, as the case may be, has been given by the Holder thereof may not be converted for shares of Common Stock on or after the date of the delivery of such Purchase Notice or Fundamental Change Purchase Notice, as the case may be, unless such Purchase Notice or Fundamental Change Purchase Notice, as the case may be, has first been validly withdrawn as specified in the following two paragraphs. A Purchase Notice or Fundamental Change Purchase Notice, as the case may be, may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent at any time prior to 5:00 p.m. New York City time on the Business Day prior to the Purchase Date or the Fundamental Change Purchase Date, as the case may be, to which it relates specifying: (a) if certificated, the certificate number of the Notes in respect of which such notice of withdrawal is being submitted, or, if not certificated, the written notice of withdrawal must comply with appropriate Depositary procedures; (b) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted; and (c) the principal amount, if any, of such Notes which remains subject to the original Purchase Notice or Fundamental Change Purchase Notice, as the case may be, and which has been or shall be delivered for purchase by the Company.

The 21 Paying Agent shall promptly return to the respective Holders thereof any Notes (x) with respect to which a Purchase Notice or Fundamental Change Purchase Notice, as the case may be, has been withdrawn in compliance with this Supplemental Indenture, or (y) held by it during the continuance of an Event of Default (other than a default that is cured by the payment of the Purchase Price or Fundamental Change Purchase Price, as the case may be) in which case, upon such return, the Purchase Notice or Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn. Section 703 Notes Purchased in Part. Any Notes that are 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 and 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 or the Authenticating Agent shall authenticate and deliver to the Holder of such Notes, without service charge, a new Note or Notes, 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 Notes so surrendered which is not purchased or redeemed. Section 704 Covenant to Comply with Securities Laws Upon Purchase of Notes.

Section 705 Repayment to the Company.

Section 706 Officers' Certificate. At least five Business Days before the Company Notice Date, the Company shall deliver an Officers' Certificate to the Trustee (provided, that at the Company's option, the matters to be addressed in such Officers' Certificate may be divided among two such certificates) specifying: (a) the manner of payment selected by the Company; and 22 (b) whether the Company desires the Trustee to give the Company Notice required by Section 701 herein. ARTICLE VIII Conversion of Notes Section 801 Right to Convert. A Holder may convert its Notes for Common Stock at any time during which the conditions stated in paragraph 10 of the Notes are met. The number of shares of Common Stock issuable upon conversion of a Note per $1,000 principal amount (the "Conversion Rate") shall be that set forth in paragraph 10 in the Notes, subject to adjustment as herein set forth. The initial Conversion Rate is 86.3558 shares of Common Stock issuable upon conversion of a Convertible Note per $1,000 principal amount. A Holder may convert a portion of the principal amount of Notes if the portion is $1,000 or a multiple of $1,000. Section 802 Conversion Procedures. To convert Notes, a Holder must satisfy the requirements in this Section 802 and in paragraph 10 of the Notes. The date on which the Holder satisfies all those requirements is the conversion date (the "Conversion Date"). As soon as practicable, but in no event later than the fifth Business Day following the Conversion Date, the Company shall deliver to the Holder, through the Conversion Agent, a certificate for the number of full shares of Common Stock issuable upon the conversion and cash in lieu of any fractional share determined pursuant to Section 803. The Person in whose name the certificate is registered shall be treated as a stockholder of record on and after the Conversion Date; provided, however, that no surrender of Notes 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; such conversion shall be at the Conversion Rate in effect on the date that such Notes shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of Notes, such Person shall no longer be a Holder of such Notes. No payment or adjustment shall be made for dividends on or other distributions with respect to any Common Stock except as provided in Section 806 or as otherwise provided in this Indenture. On conversion of Notes, that portion of accrued interest including accrued Contingent Interest, if any, with respect to the converted Notes shall not be canceled, 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 Notes 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 interest 23 accrued and unpaid through the Conversion Date and accrued and unpaid Contingent Interest, 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 principal amount of the Notes being converted pursuant to the provisions hereof. Notwithstanding conversion of any Notes, the Holders of the Notes and any Common Stock issuable upon conversion thereof will continue to be entitled to receive Additional Amounts in accordance with the Registration Rights Agreement. If a Holder converts more than one Note at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the total principal amount of the Notes converted. Upon surrender of a Note that is converted in part, the Company shall execute, and the Trustee or the Authenticating Agent shall authenticate and deliver to the Holder, a new Note in an authorized denomination equal in principal amount to the unconverted portion of the Note surrendered. If the last day on which Notes may be converted is a legal holiday in a place where a Conversion Agent is located, the Notes may be surrendered to that Conversion Agent on the next succeeding day that it is not a legal holiday. Section 803 Cash Payments in Lieu of Fractional Shares. The Company shall not issue a fractional share of Common Stock upon conversion of Notes. Instead the Company shall deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined to the nearest 1/10,000th of a share by multiplying the Last Reported Sale Price of a full share of Common Stock on the Trading Day immediately preceding the Conversion Date by the fractional amount and rounding the product to the nearest whole cent. Section 804 Taxes on Conversion. If a Holder converts Notes, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon the 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 certificates 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 shall be due because the shares are to be issued in a name other than the Holder's name. Nothing herein shall preclude any withholding tax required by law. Section 805 Covenants of the Company. The Company shall, prior to issuance of any Notes hereunder, 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 the Notes. All shares of Common Stock delivered upon conversion of the Notes shall be newly issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim. 24 The Company shall endeavor promptly to comply with all federal and state securities laws regulating the order and delivery of shares of Common Stock upon the conversion of Notes, if any, and shall cause to have listed or quoted all such shares of Common Stock on each United States national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted. Section 806 Adjustments to Conversion Rate. The Conversion Rate shall be adjusted from time to time, without duplication, as follows: (a) In case the Company shall (i) pay a dividend, or make a distribution, exclusively in shares of its capital stock, on the Common Stock; (ii) subdivide its outstanding Common Stock into a greater number of shares; (iii) combine its outstanding Common Stock into a smaller number of shares; or (iv) reclassify its Common Stock, the Conversion Rate in effect immediately prior to the record date or effective date, as the case may be, for the adjustment pursuant to this Section 806(a) as described below, shall be adjusted so that the Holder of any Notes thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock of the Company which such Holder would have owned or have been entitled to receive after the happening of any of the events described above had such Notes been converted immediately prior to such record date or effective date, as the case may be. An adjustment made pursuant to this Section 806(a) shall become effective immediately after the applicable record date in the case of a dividend or distribution and shall become effective immediately after the applicable effective date in the case of subdivision, combination or reclassification of the Company's Common Stock. If any dividend or distribution of the type described in clause (i) above is not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. (b) In case the Company shall issue rights or warrants to all holders of the Common Stock entitling them (for a period expiring within 60 days after the date of issuance of such rights or warrants) to subscribe for or purchase Common Stock at a price per share less than the Market Price per share of Common Stock on the record date fixed for determination of shareholders entitled to receive such rights or warrants, the Conversion Rate in effect immediately after such record date shall be adjusted so that the same shall equal the Conversion Rate determined by multiplying the Conversion Rate in effect immediately after such record date by a fraction of which (i) 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 for subscription or purchase, and (ii) 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 so offered would purchase at the Market Price per share of Common Stock on the earlier of such record date or the Trading Day immediately preceding the ex date for such issuance of rights or warrants. Such adjustment shall be made successively whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the record date for the determination of shareholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion 25 Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such record date for the determination of shareholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants, the value of such consideration, if other than cash, to be determined by the Board of Directors. (c) In case the Company shall, by dividend or otherwise, distribute to all holders of Common Stock any assets, debt securities or rights or warrants to purchase any of its securities (excluding (i) any dividend, distribution or issuance covered by those referred to in Section 806(a) or 806(b) hereof, (ii) any dividend or distribution paid exclusively in cash, and (iii) all distributions of common stock of Reliant Resources, Inc., a Delaware corporation, or of Texas Genco made by the Company prior to the date of this Supplemental Indenture) (any of the foregoing hereinafter in this Section 806(c) called the "Distributed Assets or Securities") in an aggregate amount per share of Common Stock that, combined together with the aggregate amount of any other such distributions to all holders of its Common Stock made within the 12 months preceding the date of payment of such distribution, and in respect of which no adjustment pursuant to this Section 806(c) has been made, exceeds 15% of the Market Price on the Trading Day immediately preceding the declaration of such distribution, then, the Conversion Rate shall be adjusted so that the same shall equal the Conversion Rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date mentioned below by a fraction of which (A) the numerator shall be the Market Price per share of the Common Stock on the earlier of such record date or the Trading Day immediately preceding the ex date for such dividend or distribution, and (B) the denominator shall be (1) the Market Price per share of the Common Stock on the earlier of such record date or the Trading Day immediately preceding the ex date for such dividend or distribution less (2) the Fair Market Value on the earlier of such record date or the Trading Day immediately preceding the ex date for such dividend or distribution (as determined by the Board of Directors, whose determination shall be conclusive, and described in a certificate filed with the Trustee and the Paying Agent) of the Distributed Assets or Securities so distributed applicable to one share of Common Stock. Such adjustment shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution; provided, however, that, if (i) the Fair Market Value of the portion of the Distributed Assets or Securities so distributed applicable to one share of Common Stock is equal to or greater than the Market Price of the Common Stock on the record date for the determination of shareholders entitled to receive such distribution or (ii) the Market Price of the Common Stock on the record date for the determination of shareholders entitled to receive such distribution is greater than the Fair Market Value per share of such Distributed Assets or Securities by less than $1.00, then, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion, in addition to the shares of Common Stock, the kind and amount of assets, debt securities, or rights or warrants comprising the Distributed Assets or Securities the Holder would have received had such Holder converted such Notes immediately prior to the record date for the determination of shareholders entitled to receive such distribution. In the event that such distribution is not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such distribution had not been declared. 26 (d) In case the Company shall make (i) any distributions, by dividend or otherwise, during any quarterly fiscal periods consisting exclusively of cash to all holders of outstanding shares of Common Stock in an aggregate amount that, together with (ii) other all-cash distributions made to all holders of outstanding shares of Common Stock during such quarterly fiscal period, and (iii) any cash and the Fair Market Value, as of the expiration of any tender or exchange offer (other than consideration payable in respect of any odd-lot tender offer) of consideration payable in respect of any tender or exchange offer by the Company or any of the Company's Subsidiaries for all or any portion of shares of Common Stock concluded during such quarterly fiscal period, exceed the product of $0.10 (appropriately adjusted from time to time for any stock dividends on or subdivisions or combinations of the Common Stock) multiplied by the number of shares of Common Stock outstanding on the record date for such distribution, then, and in each such case, the Conversion Rate shall be adjusted so that the same shall equal the Conversion Rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive such distribution by a fraction of which (A) the numerator shall be the Market Price per share of the Common Stock on the earlier of such record date or the Trading Day immediately preceding the ex date for such dividend or distribution and (B) the denominator shall be (1) the Market Price per share of Common Stock on the earlier of such record date or the Trading Day immediately preceding the ex date for such dividend or distribution plus (2) $0.10 (appropriately adjusted from time to time for any stock dividends on or subdivisions or combination of Common Stock) less (3) an amount equal to the quotient of (x) the combined amount distributed or payable in the transactions described in clauses (i), (ii) and (iii) above during such quarterly fiscal period and (y) the number of shares of Common Stock outstanding on such record date, such adjustment to become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (e) With respect to Section 806(c) above, in the event that the Company makes any distribution to all holders of Common Stock consisting of Equity Interests in a Subsidiary or other business unit of the Company, the Conversion Rate shall be adjusted so that the same shall equal the Conversion Rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive such distribution by a fraction of which (i) the numerator shall be (x) the Spin-off Market Price per share of the Common Stock on such record date plus (y) the Spin-off Market Price per Equity Interest of the Subsidiary or other business unit of the Company on such record date and (ii) the denominator shall be the Spin-off Market Price per share of the Common Stock on such record date, such adjustment to become effective 10 Trading Days after the effective date of such distribution of Equity Interests in a Subsidiary or other business unit of the Company. (f) Upon conversion of the Notes, the Holders shall receive, in addition to the Common Stock issuable upon such conversion, the rights issued under the Rights Plan or under any future shareholder rights plan the Company implements (notwithstanding the occurrence of an event causing such rights to separate from the Common Stock at or prior to the time of conversion) unless, prior to conversion, the rights have expired, terminated or been redeemed or exchanged in accordance with the Rights Plan. If, and only if, the Holders of Notes receive rights under such shareholder rights plans as described in the preceding sentence upon 27 conversion of their Notes, then no other adjustment pursuant to this Section 806 shall be made in connection with such shareholder rights plans. (g) For purposes of this Section 806, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. (h) Notwithstanding the foregoing, in no event shall the Conversion Rate exceed the maximum conversion rate specified under this Section 806(h) (the "Maximum Conversion Rate") as a result of an adjustment pursuant to Section 806(c) and Section 806(d) hereof. The Maximum Conversion Rate shall initially be 129.5337 and shall be appropriately adjusted from time to time for any stock dividends on or subdivisions or combinations of the Common Stock. The Maximum Conversion Rate shall not apply to any adjustments made pursuant to any of the events in Section 806(a) or Section 806(b) hereof. Section 807 Calculation Methodology. No adjustment in the Conversion Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect, provided that any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any subsequent adjustment. Except as stated in this Article VIII, the Conversion Rate will not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or carrying the right to purchase any of the foregoing. Any adjustments that are made shall be carried forward and taken into account in any subsequent adjustment. All calculations under Article VII, Section 806 and this Section 807 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be. Section 808 When No Adjustment Required. No adjustment to the Conversion Rate need be made: (a) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan; (b) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries; (c) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security not described in paragraph (b) above and outstanding as of the date of this Supplemental Indenture; (d) upon the issuance of any shares of Common Stock pursuant to warrants granted in connection with the Company's $3.8 Billion Credit Facility; (e) for a change in the par value or no par value of the Common Stock; or 28 (f) for accrued and unpaid interest (including Contingent Interest or Additional Amount, if any). To the extent the Notes become convertible into cash, assets, or property (other than capital stock of the Company or securities to which Section 812 applies), no adjustment shall be made thereafter as to the cash, assets or property. Interest shall not accrue on such cash. Section 809 Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders a notice of the adjustment. The Company shall file with the Trustee and the Conversion Agent such notice. The certificate shall, absent manifest error, be conclusive evidence that the adjustment is correct. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate except to exhibit the same to any Holder desiring inspection thereof. Section 810 Voluntary Increase. The Company may make such increases in the Conversion Rate, in addition to those required by Section 806, as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. To the extent permitted by applicable law, the Company may from time to time increase the Conversion Rate by any amount for any period of time if the period is at least 20 days, the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is so increased, the Company shall mail to Holders and file with the Trustee and the Conversion Agent a notice of such increase. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such notice except to exhibit the same to any Holder desiring inspection thereof. The Company shall mail the notice at least 15 days before the date the increased Conversion Rate takes affect. The notice shall state the increased Conversion Rate and the period it shall be in effect. Section 811 Notice to Holders Prior to Certain Actions. In case: (a) The Company shall declare a dividend (or any other distribution) on its Common Stock that would require an adjustment in the Conversion Rate pursuant to Section 806; (b) The Company shall authorize the granting to all or substantially all the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; (c) Of any reclassification or reorganization of the Common Stock of the Company (other than a subdivision or combination of its outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any shareholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) Of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, 29 the Company shall cause to be filed with the Trustee and to be mailed to each Holder at its address appearing on the Security Register, as promptly as possible but in any event at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution, or rights or warrants are to be determined or (y) the date on which such reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Section 812 Effect of Reclassification, Consolidation, Merger, Binding Share Exchange or Sale. If any of the following events occur, namely (a) any reclassification or change of outstanding shares of Common Stock (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, merger, combination or binding share exchange of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock; or (c) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a Supplemental Indenture, providing that each Note shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Note immediately prior to such reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance. Such Supplemental Indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 812. The Company shall cause notice of the execution of such Supplemental Indenture to be mailed to each Holder, at its address appearing on the Security Register, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, binding share exchanges, sales and conveyances. If this Section 812 applies to any event or occurrence, Section 806 shall not apply. 30 Section 813 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to either calculate the Conversion Rate or determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same and shall be protected in relying upon an Officers' Certificate with respect to the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Notes and the Trustee and any other Conversion Agent make no representations with respect thereto. Subject to the provisions of Article Five of the Original Indenture, neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Notes for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Section. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any Supplemental Indenture entered into pursuant to Article VIII hereof relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 812 or to any adjustment to be made with respect thereto, but, subject to the provisions of Article Five of the Original Indenture, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers' Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Section 814 Simultaneous Adjustments. In the event that Section 806 requires adjustments to the Conversion Rate under more than one of Sections 806(a), (b), (c) or (d), and the Record Dates for the distributions giving rise to such adjustments shall occur on the same date, then such adjustments shall be made by applying, first, the provisions of Section 806(c), second, the provisions of Section 806(a) and third, the provisions of Section 806(b); provided, however, that nothing in this Section 814 shall be done to evade the principle set forth in Section 806(h) hereof that the Maximum Conversion Rate shall not apply to any adjustments made with respect to any of the events in Section 806(a) or Section 806(b) hereof. Section 815 Successive Adjustments. After an adjustment to the Conversion Rate under Section 806, any subsequent event requiring an adjustment under Section 806 shall cause an adjustment to the Conversion Rate as so adjusted. Section 816 General Considerations. Whenever successive adjustments to the Conversion Rate are called for pursuant to Article VIII hereof, such adjustments shall be made to the Market Price as may be necessary or appropriate to effectuate the intent of Article VIII hereof and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. 31 ARTICLE IX Restrictions on Transfer Section 901 Transfer and Exchange. (a) Transfer and Exchange of Notes in Definitive Form. In addition to the requirements set forth in Section 305 of the Original Indenture, Notes in definitive form that are Transfer Restricted Securities presented or surrendered for registration of transfer or exchange pursuant to Section 305 of the Original Indenture shall be accompanied by the following additional information and documents, as applicable, upon which the Security Registrar may conclusively rely: (i) if such Transfer Restricted Securities are being delivered to the Security Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect (in substantially the form of Exhibit B hereto); or (ii) if such Transfer Restricted Securities are being transferred (1) to a Qualified Institutional Buyer in accordance with Rule 144A under the Securities Act or (2) pursuant to an exemption from registration in accordance with Rule 144 under the Securities Act (and based upon an opinion of counsel if the Company or the Trustee so requests) or (3) pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form of Exhibit B hereto); or (iii) if such Transfer Restricted Securities are being transferred to a Non-U.S. Person pursuant to an exemption from registration in accordance with Rule 904 of Regulation S under the Securities Act, certifications to that effect from such transferor (in substantially the form of Exhibits B and C hereto) and an opinion of counsel to that effect if the Company or the Trustee so requests; or (iv) if such Transfer Restricted Securities are being transferred in reliance on and in compliance with another exemption from the registration requirements of the Securities Act, a certification to that effect from such Holder (in substantially the form of Exhibit B hereto) and an opinion of counsel to that effect if the Company or the Trustee so requests.

Section 902 Legends. (a) Except as permitted by Section 902(b) hereof, each certificate evidencing the Global Notes or certificated notes in definitive form (and all Notes issued in exchange therefor or substitution thereof) shall bear a legend in substantially the following form: THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933 (THE "SECURITIES ACT"), AND THIS SECURITY AND THE COMMON STOCK ISSUABLE UPON CONVERSION HEREOF MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY AND THE COMMON STOCK ISSUABLE UPON CONVERSION HEREOF MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (III) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (IV) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (IV) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, 33 NOTIFY ANY PURCHASER OF THE SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. THE HOLDER OF THIS SECURITY AGREES THAT SUCH HOLDER WILL NOT ENGAGE IN HEDGING TRANSACTIONS INVOLVING THIS SECURITY AND THE COMMON STOCK ISSUABLE UPON CONVERSION HEREOF UNLESS IN COMPLIANCE WITH THE SECURITIES ACT. THIS SECURITY AND ANY RELATED DOCUMENTATION MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME TO MODIFY THE RESTRICTIONS ON AND PROCEDURES FOR RESALES AND OTHER TRANSFERS OF THIS SECURITY TO REFLECT ANY CHANGE IN APPLICABLE LAW OR REGULATION (OR THE INTERPRETATION THEREOF) OR IN PRACTICES RELATING TO THE RESALE OR TRANSFER OF RESTRICTED SECURITIES GENERALLY. THE HOLDER OF THIS SECURITY SHALL BE DEEMED BY THE ACCEPTANCE OF THIS SECURITY TO HAVE AGREED TO ANY SUCH AMENDMENT OR SUPPLEMENT. THE HOLDER OF THIS SECURITY IS SUBJECT TO, AND ENTITLED TO THE BENEFITS OF, A REGISTRATION RIGHTS AGREEMENT, DATED AS OF MAY 19, 2003 ENTERED INTO BY THE COMPANY FOR THE BENEFIT OF CERTAIN HOLDERS OF SECURITIES FROM TIME TO TIME. THE HOLDER OF THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SECURITY IS SUBJECT TO, AND ENTITLED TO THE BENEFITS OF, A RIGHTS AGREEMENT, DATED AS OF JANUARY 1, 2002, BETWEEN THE COMPANY AND JPMORGAN CHASE BANK, AS RIGHTS AGENT. Each certificate evidencing the Global Notes also shall bear the legend specified for Global Notes in the form of Note attached hereto as Exhibit A. (b) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Note) pursuant to Rule 144 under the Securities Act or an effective registration statement under the Securities Act, which shall be certified to the Trustee and Security Registrar upon which each may conclusively rely: (i) in the case of any Transfer Restricted Security represented by a certificated note, the Security Registrar shall permit the Holder thereof to exchange such Transfer Restricted Security for a certificated note that does not bear the legend set forth in Section 902(a) hereof and rescind any restriction on the transfer of such Transfer Restricted Security; and 34 (ii) in the case of any Transfer Restricted Security represented by a Global Note, such Transfer Restricted Security shall not be required to bear the legend set forth in Section 902(a) hereof if all other interests in such Global Note have been or are concurrently being sold or transferred pursuant to Rule 144 under the Securities Act or pursuant to an effective registration statement under the Securities Act. Section 903 Registration Rights Agreement. The Company shall perform its obligations under the Registration Rights Agreement and shall comply in all material respects with the terms and conditions contained therein including, without limitation, the payment of Additional Amounts. Section 904 Restriction on Common Stock Issuable Upon Conversion. (a) Shares of Common Stock to be issued upon conversion of Notes prior to the effectiveness of a Shelf Registration Statement shall be physically delivered in certificated form to the Holders converting such Notes and the certificate representing such shares of Common Stock shall bear the Restricted Common Stock Legend unless removed in accordance with Section 904(c). (b) If (i) shares of Common Stock to be issued upon conversion of Notes prior to the effectiveness of a Shelf Registration Statement are to be registered in a name other than that of the Holder of such Notes or (ii) shares of Common Stock represented by a certificate bearing the Restricted Common Stock Legend are transferred subsequently by such Holder, then, unless the Shelf Registration Statement has become effective and such shares are being transferred pursuant to the Shelf Registration Statement, the Holder must deliver to the transfer agent for the Common Stock and to the Company a certificate in substantially the form of Exhibit I as to compliance with the restrictions on transfer applicable to such shares of Common Stock and neither the transfer agent nor the registrar for the Common Stock shall be required to register any transfer of such Common Stock not so accompanied by a properly completed certificate. (c) Except in connection with a Shelf Registration Statement, if certificates representing shares of Common Stock are issued upon the registration of transfer, exchange or replacement of any other certificate representing shares of Common Stock bearing the Restricted Common Stock Legend, or if a request is made to remove such Restricted Common Stock Legend from certificates representing shares of Common Stock, the certificates so issued shall bear the Restricted Common Stock Legend, or the Restricted Common Stock Legend shall not be removed, as the case may be, unless there is delivered to the Company such reasonably satisfactory evidence, which, in the case of a transfer made pursuant to Rule 144 under the Securities Act of 1933, may include an opinion of counsel, as may be reasonably required by the Company, that neither the legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A, Rule 144 or Regulation S under the Securities Act of 1933 and that such shares of Common Stock are securities that are not "restricted" within the meaning of Rule 144 under the Securities Act of 1933. Upon provision to the Company of such reasonably satisfactory evidence, the Company shall cause the transfer agent for the Common Stock to countersign and deliver certificates representing shares of Common Stock that do not bear the legend. 35 Section 905 Delivery of Certain Information. At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act, upon the request of a Holder or any beneficial holder of Notes or shares of Common Stock issued upon conversion thereof, the Company will promptly furnish or cause to be furnished Rule 144A Information (as defined below) to such Holder or any beneficial holder of Notes or holder of shares of Common Stock issued upon conversion of Notes, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. "Rule 144A Information" shall be such information as is specified pursuant to Rule 144A(d)(4) under the Securities Act.

INTEREST This Note shall bear interest at a rate of 3.75% per year on the principal hereof, from May 19, 2003 or from the most recent Interest Payment Date (as defined below) to which payment has been made or duly provided for, payable semiannually in arrears on May 15 and November 15 of each year, beginning November 15, 2003 (each an "Interest Payment Date") to the persons in whose names the Notes are registered at the close of business on May 1 and November 1 (each a "Regular Record Date") (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. This Note shall also bear Contingent Interest in certain circumstances as specified in paragraph 5 below. The amount of interest payable for any period shall be computed on the basis of a 360-day year of twelve 30-day months. The amount of interest payable for any partial period shall be computed on the basis of a 360-day year of twelve 30-day months and the days elapsed in any partial month. Holders of Notes at the close of business on a Regular Record Date will receive payment of interest, including Contingent Interest, if any, payable on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time after the close of business on such Regular Record Date. Notes surrendered for conversion by a Holder during the period from the close of business on any Regular Record Date to the opening of business on the immediately following Interest Payment Date must be accompanied by payment of an amount equal to the interest, including Contingent Interest, if any, that the Holder is to receive on the Notes; provided, however, that no such payment need be made if (1) the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the immediately following Interest Payment Date, (2) the Company has specified a Purchase Date following a Fundamental Change that is during such period or (3) any overdue interest (including overdue Contingent Interest, if any) exists at the time of conversion with respect to such Notes to the extent of such overdue interest. The Holders of the Notes and any Common Stock issuable upon conversion thereof will continue to be entitled to receive Additional Amounts in accordance with the Registration Rights Agreement. If the principal hereof or any portion of such principal is not paid when due (whether upon acceleration, upon the date set for payment of the Redemption Price pursuant to paragraph 6 hereof, upon the date set for payment of a Purchase Price or Fundamental Change Purchase Price pursuant to paragraph 8 hereof or upon the Stated Maturity of this Note) or if interest (including Contingent Interest, if any) due hereon or any portion of such interest is not paid when due in accordance with this paragraph or paragraph 5 or 11 hereof, then in each such case the overdue amount shall bear interest at the rate of 3.75% per annum, compounded semiannually (to the extent that the payment of such interest shall be legally enforceable), which interest shall accrue from the date such overdue amount was due to the date payment of such amount, A-6 including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. 2. METHOD OF PAYMENT Payment of the principal of (and premium, if any) and any such interest on this Note will be made at the Corporate Trust Office of the Trustee, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer in immediately available funds at such place and to such account as may be designated in writing by the Person entitled thereto as specified in the Security Register. 3.

INDENTURE This Note is one of a duly authorized issue of securities of the Company, issued and to be issued in one or more series under an Indenture, dated as of May 19, 2003 (the "Original Indenture"), as supplemented by the First Supplemental Indenture thereto, dated as of May 19, 2003 (the "Supplemental Indenture" and, together with the Original Indenture, the "Indenture"), between the Company and the Trustee. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. Reference is hereby made to the Indenture for a statement of the respective rights thereunder of the Company, the Trustee and the Holders and the terms upon which the Notes are to be authenticated and delivered. The terms, conditions and provisions of the Notes are those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, and those set forth in the Notes. The Notes are general unsecured obligations of the Company limited to $575,000,000 aggregate principal amount. 5. CONTINGENT INTEREST The Company will pay Contingent Interest to the Holders of the Notes in respect of any six-month interest period from May 15 to November 14 or November 15 to May 14 commencing on or after May 15, 2008 for which the average Trading Price of a Note for the applicable five Trading Day reference period equals or exceeds 120% of $1,000 per $1,000 principal amount of Notes as of the day immediately preceding the first day of the applicable six-month interest period. The "five Trading Day reference period" means the five Trading Days ending on the second Trading Day immediately preceding the relevant six-month interest period. For any six-month interest period in respect of which Contingent Interest is payable, the Contingent Interest A-7 payable on each $1,000 principal amount of Notes shall equal 0.25% of the average Trading Price per $1,000 principal amount of Notes during the applicable five Trading Day reference period. The record dates and payment dates for Contingent Interest, if any, will be the same as the Regular Record Date and Interest Payment Dates for the semi-annual interest payments on the Notes. Upon determination that Holders will be entitled to receive Contingent Interest which may become payable, the Company shall notify the Holders. In connection with providing such notice, the Company will issue a press release and publish a notice containing information regarding the Contingent Interest determination in a newspaper of general circulation in The City of New York or publish such information on the Company's then existing Web site or through such other public medium as the Company shall determine. 6. REDEMPTION AT THE OPTION OF THE COMPANY No sinking fund is provided for the Notes. The Notes are redeemable for cash in whole, or in part, at any time on or after May 15, 2008 at the option of the Company at a redemption price ("Redemption Price") equal to 100% of the principal amount of the Notes to be redeemed plus any accrued and unpaid interest (including Contingent Interest and Additional Amounts, if any) to the Redemption Date. 7. NOTICE OF REDEMPTION AT THE OPTION OF THE COMPANY Notice of redemption at the option of the Company shall be mailed at least 30 days but not more than 60 days before a Redemption Date to the Trustee, the Paying Agent and each Holder of Notes to be redeemed at the Holder's registered address. If money sufficient to pay the Redemption Price of all Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on and after the Redemption Date interest (including Contingent Interest and Additional Amounts, if any), if any, shall cease to accrue on such Notes or portions thereof. Notes in denominations larger than $1,000 principal amount may be redeemed in part but only in integral multiples of $1,000 principal amount. 8. PURCHASE BY THE COMPANY AT THE OPTION OF THE HOLDER; PURCHASE AT THE OPTION OF THE HOLDER UPON A FUNDAMENTAL CHANGE (a) Subject to the terms and conditions of the Indenture, a Holder shall have the option to require the Company to purchase the Notes held by such Holder on May 15, 2008, May 15, 2013 and May 15, 2018 (each, a "Purchase Date") at a purchase price (the "Purchase Price") equal to 100% of the principal amount of the Notes to be purchased plus any accrued and unpaid interest (including Contingent Interest and Additional Amounts, if any) to such Purchase Date, upon delivery of a Purchase Notice containing the information set forth in the Indenture, from the opening of business on the date that is 20 Business Days prior to such Purchase Date until the close of business on the fifth Business Day prior to such Purchase Date and upon delivery of the Notes to the Paying Agent by the Holder as set forth in the Indenture.

(b) If a Fundamental Change shall occur at any time prior to May 15, 2008, each Holder shall have the right, at such Holder's option and subject to the terms and conditions of the Indenture, to require the Company to purchase any or all of such Holder's Notes or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple of $1,000 on the day that is 35 days after the date of the Company Notice of the occurrence of the Fundamental Change (subject to extension to comply with applicable law) for a Fundamental Change Purchase Price equal to 100% of the principal amount of Notes purchased plus accrued and unpaid interest (including Contingent Interest and Additional Amounts, if any) to the Fundamental Change Purchase Date, which Fundamental Change Purchase Price shall be paid by the Company in cash, as set forth in the Indenture. (c) Holders have the right to withdraw any Purchase Notice or Fundamental Change Purchase Notice, as the case may be, by delivery to the Paying Agent of a written notice of withdrawal in accordance with the provisions of the Indenture. (d) If cash sufficient to pay a Fundamental Change Purchase Price or Purchase Price, as the case may be, of all Notes or portions thereof to be purchased as of the Purchase Date or the Fundamental Change Purchase Date, as the case may be, is deposited with the Paying Agent on the Business Day following the Purchase Date or the Fundamental Change Purchase Date, as the case may be, interest (including Contingent Interest and Additional Amounts, if any) shall cease to accrue on such Notes (or portions thereof) on and after such date, and the Holder thereof shall have no other rights as such (other than the right to receive the Purchase Price or Fundamental Change Purchase Price, as the case may be, upon surrender of such Note). 9. RANKING The Notes shall be unsecured and shall rank equally in right of payment with all of the Company's other existing and future unsecured and unsubordinated Indebtedness. 10. CONVERSION Subject to the procedures set forth in the Indenture, a Holder may convert Notes into Common Stock on or before the close of business on May 15, 2023 during the periods and upon satisfaction of at least one of the conditions set forth below: (a) in any calendar quarter (and only during such calendar quarter) if the Last Reported Sale Price for Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the previous calendar quarter is greater than or equal to 120% or, following May 15, 2008, 110% of the Conversion Price per share of Common Stock on such last Trading Day; (b) during any period in which both (A) the credit rating assigned to the Notes by Moody's Investors Service, Inc. is lower than Ba2 and (B) the credit rating assigned to the Notes by Standard & Poors Rating Services is lower than BB; A-9 (c) during any period in which the Notes no longer are assigned credit ratings by at least one of Moody's Investors Services, Inc. and Standard & Poor's Ratings Services or their successors; (d) in the event that the Company calls the Notes for redemption, at any time prior to the close of business on the second Business Day immediately preceding the Redemption Date; or (e) the Company becomes a party to a consolidation, merger or binding share exchange pursuant to which the Common Stock would be converted into cash or property (other than securities), in which case a Holder may surrender Notes for conversion at any time from and after the date which is 15 days prior to the anticipated effective date for the transaction until 15 days after the actual effective date of such transaction; or (f) the Company elects to (i) distribute to all holders of Common Stock assets, debt securities or rights to purchase securities of the Company, which distribution has a per share value as determined by the Board of Directors exceeding 15% of the Last Reported Sale Price of a share of Common Stock on the Trading Day immediately preceding the declaration date for such distribution, or (ii) distribute to all holders of Common Stock rights entitling them to purchase, for a period expiring within 60 days after the date of such distribution, shares of Common Stock at less than the Last Reported Sale Price of Common Stock on the Trading Day immediately preceding the declaration date of the distribution. In the case of the foregoing clauses (i) and (ii), the Company must notify the Holders at least 20 Business Days immediately prior to the ex date for such distribution. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time thereafter until the earlier of the close of business on the Business Day immediately prior to the ex date or the Company's announcement that such distribution will not take place; provided, however, that a Holder may not exercise this right to convert if the Holder may participate in the distribution without conversion. As used herein, the term "ex date," when used with respect to any issuance or distribution, shall mean the first date on which the Common Stock trades regular way on such exchange or in such market without the right to receive such issuance or distribution. Notes in respect of which a Holder has delivered a notice of exercise of the option to require the Company to purchase such Notes pursuant to Articles V or VI of the Indenture may be converted only if the notice of exercise is withdrawn in accordance with the terms of the Indenture. The initial Conversion Rate is 86.3558 shares of Common Stock per $1,000 principal amount, subject to adjustment in certain events described in the Indenture. The Company shall deliver cash or a check in lieu of any fractional share of Common Stock. Holders of Notes at the close of business on a Regular Record Date will receive payment of interest, including Contingent Interest, if any, payable on the corresponding Interest Payment Date notwithstanding the conversion of such Notes at any time after the close of business on such Regular Record Date. Notes surrendered for conversion by a Holder during the period from the close of business on any Regular Record Date to the opening of business on the immediately following Interest Payment Date must be accompanied by payment of an amount equal to the A-10 interest, including Contingent Interest, if any, that the Holder is to receive on the Notes; provided, however, that no such payment need be made if (1) the Company has specified a Redemption Date that is after a Regular Record Date and on or prior to the immediately following Interest Payment Date, (2) the Company has specified a Purchase Date following a Fundamental Change that is during such period, or (3) any overdue interest (including overdue Contingent Interest, if any) exists at the time of conversion with respect to such Notes to the extent of such overdue interest. The Holders of the Notes and any Common Stock issuable upon conversion thereof will continue to be entitled to receive Additional Amounts in accordance with the Registration Rights Agreement. To convert the Notes a Holder must (1) complete and manually sign the irrevocable conversion notice on the back of the Notes (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent at the office maintained by the Conversion Agent for such purpose, (2) surrender the Notes to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required. A Holder may convert a portion of the Notes only if the principal amount of such portion is $1,000 or a multiple of $1,000. No payment or adjustment shall be made for dividends on the Common Stock except as provided in the Indenture. On conversion of the Notes, that portion of accrued and unpaid interest attributable to the period from the Original Issue Date to the Conversion Date and accrued and unpaid Contingent Interest with respect to the converted portion of the Notes shall not be canceled, 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 any cash payment in lieu of fractional shares) in exchange for the portion of the Notes 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 interest accrued and unpaid through the Conversion Date and accrued and unpaid Contingent Interest, 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 principal amount of the Notes being converted pursuant to the provisions hereof. Notwithstanding the conversion of any Notes, the Holders of the Notes and any Common Stock issuable upon conversion thereof will continue to be entitled to receive Additional Amounts in accordance with the Registration Rights Agreement. 11. DEFAULTED INTEREST Except as otherwise specified with respect to the Notes, any Defaulted Interest on any Note shall forthwith cease to be payable to the registered Holder thereof on the relevant Regular Record Date or accrual date, as the case may be, by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 204 of the Supplemental Indenture. 12. DENOMINATIONS; TRANSFER; EXCHANGE The Notes are in registered form, without coupons, in denominations of $1,000 principal amount and multiples of $1,000; provided, however, that Notes issued to institutional accredited A-11 investors will be issued only in denominations of $250,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or convert Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. In the event of any redemption or purchase in part, the Security Registrar need not register the transfer of or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) or any Notes in respect of which a Purchase Notice or Fundamental Change Purchase Notice has been given and not withdrawn (except, in the case of a Note to be purchased in part, the portion of the Note not to be purchased) for a period of 15 days before the mailing of a Redemption Notice, Purchase Notice or Fundamental Change Purchase Notice. 13. PERSONS DEEMED OWNERS The registered Holder of this Note may be treated as the owner of this Note for all purposes. 14. UNCLAIMED MONEY OR PROPERTY The Trustee and the Paying Agent shall return to the Company upon written request any money or property held by them for the payment of any amount with respect to the Notes that remains unclaimed for two years, provided, however, that the Trustee or such Paying Agent, before being required to make any such return, shall at the expense of the Company cause to be published once in a newspaper of general circulation in The City of New York or mail to each such Holder notice that such money or property remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing, any unclaimed money or property then remaining shall be returned to the Company. After return to the Company, Holders entitled to the money or property must look to the Company for payment as general creditors unless an applicable abandoned property law designates another Person. 15. AMENDMENT; WAIVER Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Notes may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes at the time Outstanding and (ii) certain defaults or noncompliance with certain provisions may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding. The Indenture or the Notes may be amended without the consent of any Holders under circumstances set forth in Section 901 of the Original Indenture. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 16. DEFAULTS AND REMEDIES If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding, may declare the A-12 principal amount and any accrued and unpaid interest (including Contingent Interest and Additional Amounts, if any), of all the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which shall result in the Notes being declared due and payable immediately upon the occurrence of such Events of Default. Events of Default in respect of the Notes are set forth in Section 1001 of the Supplemental Indenture and Section 501 of the Original Indenture. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives reasonable indemnity or security. Subject to certain limitations, conditions and exceptions, Holders of a majority in aggregate principal amount of the Notes at the time Outstanding may direct the Trustee in its exercise of any trust or power, including the annulment of a declaration of acceleration. The Trustee may withhold from Holders notice of any continuing default (except a default in payment on any Notes) if it determines that withholding notice is in their interests. 17. CONSOLIDATION, MERGER, AND SALE OF ASSETS In the event of a consolidation, merger, or sale of assets to convey, transfer or lease of all or substantially all of Company's property or assets as described in Article VIII of the Original Indenture, the successor corporation to the Company shall succeed to and be substituted for the Company, and may exercise the Company's rights and powers under this Indenture, and thereafter, except in the case of a lease, the Company shall be relieved of all obligations and covenants under the Indenture and the Notes. 18.
