Interest shall be payable at the office of the Company maintained by the Company for such purposes in the Borough of Manhattan, The City of New York, which shall initially be the Corporate Trust Office of the Trustee and may, as the Company shall specify to the paying agent in writing by each record date, be paid either (i) by check mailed to the address of the Person entitled thereto as it appears in the Note register (provided that any holder of Notes with an aggregate principal amount in excess of $2,000,000 shall, at the written election of such holder (such election to be made prior to the relevant record date and to contain appropriate wire transfer information), be paid by wire transfer in immediately available funds) or (ii) by transfer to an account maintained by such Person located in the United States; provided that payments to the Depositary will be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

10

cease to be payable to the Noteholder on the relevant record date by virtue of his having been such Noteholder, and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall provide an Officers’ Certificate to the Trustee specifying the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than twenty-five (25) days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided.

Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (2) of this Section 2.03.

          (2) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

     Section 2.04. Execution and Authentication of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of its Chairman of the Board of Directors, Vice Chairman of the Board of Directors, Chief Executive Officer, President, Chief Financial Officer or any Vice President and attested by its Treasurer or any Assistant Treasurer, or its Secretary or any Assistant Secretary. The signature of any of these officers on the Notes may be manual or facsimile.

11

valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

          In case any officer of the Company who shall have signed any of the Notes shall cease to be such officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such officer of the Company, and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an officer.

          Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Company designated pursuant to Section 4.02 being herein sometimes collectively referred to as the “Note register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. The Note register shall be in written form or in any form capable of being converted into written form within a reasonably prompt period of time. The Trustee is hereby appointed “Note registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or more co-registrars in accordance with Section 4.02.

          Upon surrender for registration of transfer of any Note to the Note registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

          Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding.

          All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

          All Notes presented or surrendered for registration of transfer or for exchange, redemption, repurchase or conversion shall (if so required by the Company or the Note registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form

12

satisfactory to the Company or the Note registrar, as the case may be, and the Notes shall be duly executed by the Noteholder thereof or his attorney duly authorized in writing.

          No service charge shall be made to any holder for any registration of transfer or exchange of Notes, but either the Company, the Trustee or both may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

          Neither the Company nor the Trustee nor any Note registrar shall be required to exchange or register a transfer of (a) any Notes for a period of fifteen (15) days next preceding any selection of Notes to be redeemed, (b) any Notes or portions thereof called for redemption pursuant to Section 3.02, (c) any Notes or portions thereof surrendered for conversion pursuant to Article 14, (d) any Notes or portions thereof tendered for redemption (and not withdrawn) pursuant to Section 3.05 or (e) any Notes or portions thereof tendered for repurchase (and not withdrawn) pursuant to Section 3.06.

     (b) The following provisions shall apply only to Global Notes:

     (i) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or Custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

     (ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (A) the Depositary (i) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note or (ii) has ceased to be a clearing agency registered under the Exchange Act and a successor Depositary is not appointed by the Company within 90 days, (B) an Event of Default has occurred and is continuing and the maturity of the Notes shall have been accelerated in accordance with the terms of the Notes and any holder shall have requested in writing the issuance of definitive certificated securities, or (C) the Company, in its sole discretion, notifies the Trustee in writing that it no longer wishes to have all the Notes represented by Global Notes. Any Global Note exchanged pursuant to clause (A) or (B) above shall be so exchanged in whole and not in part and any Global Note exchanged pursuant to clause (C) above may be exchanged in whole or from time to time in part as directed by the Company. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.

     (iii) Notes issued in exchange for a Global Note or any portion thereof pursuant to clause (ii) above and which is not a Global Note shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall

13

designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Note registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Note issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

     (iv) In the event of the occurrence of any of the events specified in clause (ii) above, the Company will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form, without interest coupons.

     (v) Neither any members of, or participants in, the Depositary (“Agent Members”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, 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 Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall 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 such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a holder of any Note.

     (vi) At such time as all interests in a Global Note have been redeemed, repurchased, converted, canceled or exchanged for Notes in certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is redeemed, repurchased, converted, canceled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction.

          (c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Common Stock issued upon conversion of the Notes and required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legend below) unless such restrictions on transfer shall be waived by written consent of the Company, and the holder of each such Restricted Security, by such Noteholder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Sections 2.05(c) and 2.05(d), the term “transfer” encompasses any sale,

14

pledge, loan, transfer, assignment, conveyance or other disposition whatsoever of any Restricted Security or any interest therein.

          Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form, unless such Note has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer), or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee:

THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT); (2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE NOTE EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), RESELL OR OTHERWISE TRANSFER THIS NOTE OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE EXCEPT (A) TO NII HOLDINGS, INC. OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (3) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (2)(D) ABOVE), IT WILL FURNISH TO WILMINGTON TRUST COMPANY, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THE TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (4) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THIS NOTE PURSUANT TO CLAUSE (2)(D) ABOVE OR UPON ANY TRANSFER OF THIS NOTE UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION). THE

15

INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTION.

          Any Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms or as to conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of such Note for exchange to the Note registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by this Section 2.05(c). If the Restricted Security surrendered for exchange is represented by a Global Note bearing the legend set forth in this Section 2.05(c), the principal amount of the legended Global Note shall be reduced by the appropriate principal amount and the principal amount of a Global Note without the legend set forth in this Section 2.05(c) shall be increased by an equal principal amount. If a Global Note without the legend set forth in this Section 2.05(c) is not then outstanding, the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary.

          (d) Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), any stock certificate representing Common Stock issued upon conversion of any Note shall bear a legend in substantially the following form, unless such Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or such Common Stock has been issued upon conversion of Notes that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act, or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent:

THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. THE HOLDER HEREOF AGREES THAT, UNTIL THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE COMMON STOCK EVIDENCED HEREBY, UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO NII HOLDINGS, INC. OR TO ANY SUBSIDIARY THEREOF, (B) TO A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (D) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER); (2) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER

16

PURSUANT TO CLAUSE (1)(D) ABOVE), IT WILL FURNISH TO EQUISERVE TRUST COMPANY, N.A., AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE (1)(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE (1)(D) ABOVE OR UPON ANY TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY AFTER THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION).

          Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the restrictive legend required by this Section 2.05(d).

          (e) Any Note or Common Stock issued upon the conversion of a Note that, prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144 under the Securities Act).

          Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case, the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

17

          Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in the preceding paragraph, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, either the Company, the Trustee or both may require the payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been called for redemption or has been tendered for redemption upon a Designated Event (and not withdrawn) or has been surrendered for repurchase on a Repurchase Date (and not withdrawn) or is to be converted into Common Stock or cash shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, the Trustee and, if applicable, any paying agent or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

          Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or redemption or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion or redemption or repurchase of negotiable instruments or other securities without their surrender.

          Section 2.07. Temporary Notes. Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount

18

of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered hereunder.

          Section 2.08. Cancellation of Notes. If the Company shall acquire any of the Notes, such acquisition shall not operate as a redemption, repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation. All Notes surrendered for the purpose of payment, redemption, repurchase, conversion, exchange or registration of transfer shall, if surrendered to the Company or any paying agent or any Note registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its customary procedures. Any Notes surrendered by the Company to the Trustee for cancellation shall be accompanied by an Officers’ Certificate requesting the Trustee to effect such cancellation.

          Section 2.09. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Noteholders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers.

ARTICLE III

          Section 3.01. Redemption of Notes at the Option of the Company. Except as otherwise provided in Section 3.05, the Company may not redeem any Notes prior to February 7, 2011. At any time on or after February 7, 2011, the Notes may be redeemed at the option of the Company (an “Optional Redemption”), in whole or in part, upon notice as set forth in Section 3.02, at any time for a redemption price in cash equal to 100% of the principal amount of the notes to be redeemed, together with any accrued and unpaid interest (including additional amounts, if any) up to but excluding the date fixed for redemption. The notes are not subject to redemption through the operation of any sinking fund.

          Section 3.02. Notice of Optional Redemption; Selection of Notes. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any part of the Notes pursuant to Section 3.01, it shall fix a date for redemption and it or, at its written request received by the Trustee not fewer than forty-five (45) days prior (or such shorter period of time as may be acceptable to the Trustee) to the date fixed for redemption, the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed a notice of such redemption not fewer than thirty (30) nor more than sixty (60) days prior to the redemption date (any such

19

date an “Optional Redemption Notice Date”) to each holder of Notes so to be redeemed as a whole or in part at its last address as the same appears on the Note register; provided that if the Company shall give such notice, it shall give substantially concurrent written notice of the redemption date to the Trustee. Such mailing shall be by first class mail. The notice, if mailed in the manner herein provided, shall be conclusively presumed to have been duly given, whether or not the holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Concurrently with the mailing of any such notice of redemption, the Company shall issue a press release announcing such redemption, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the redemption notice or any of the proceedings for the redemption of any Note called for redemption.

          Each such notice of redemption shall specify the aggregate principal amount of Notes to be redeemed, the CUSIP number or numbers of the Notes being redeemed, the date fixed for redemption (which shall be a Business Day), the redemption price at which Notes are to be redeemed, the place or places of payment, that payment will be made upon presentation and surrender of such Notes, that interest accrued to the date fixed for redemption will be paid as specified in said notice, and that on and after said date interest thereon or on the portion thereof to be redeemed will cease to accrue. Such notice shall also state (x) the current Conversion Rate and the date on which the right to convert such Notes or portions thereof will expire and (y) the Company’s election to deliver shares of Common Stock or to pay cash in lieu of delivery of shares of Common Stock with respect to any Notes or portions thereof converted prior to the redemption date. If fewer than all the Notes are to be redeemed, the notice of redemption shall identify the Notes to be redeemed (including CUSIP numbers, if any). In case any Note is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that, on and after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion thereof will be issued.

          On or prior to the redemption date specified in the notice of redemption given as provided in this Section 3.02, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as the paying agent, set aside, segregate and hold in trust as provided in Section 4.04) an amount of money in immediately available funds sufficient to redeem on the redemption date all the Notes (or portions thereof) so called for redemption (other than those theretofore surrendered for conversion) at the appropriate redemption price, together with accrued interest to, but excluding, the redemption date; provided that if such payment is made on the redemption date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time on such date. The Company shall be entitled to retain any interest, yield or gain on amounts deposited with the Trustee or any paying agent pursuant to this Section 3.02 in excess of amounts required hereunder to pay the redemption price and accrued interest to, but excluding, the redemption date. If any Note called for redemption is converted pursuant hereto prior to such redemption date, any money deposited with the Trustee or any paying agent or so segregated and held in trust for the redemption of such Note shall be paid to the Company upon its written request, or, if then held by the Company, shall be discharged from such trust. Whenever any Notes are to be redeemed pursuant to

20

Section 3.01, the Company will give the Trustee written notice in the form of an Officers’ Certificate not fewer than forty-five (45) days (or such shorter period of time as may be acceptable to the Trustee) prior to the redemption date as to the aggregate principal amount of Notes to be redeemed.

          If less than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof of the Global Note or the Notes in certificated form to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method the Trustee deems fair and appropriate. If any Note selected for partial redemption is submitted for conversion in part after such selection, the portion of such Note submitted for conversion shall be deemed (so far as may be possible) to be the portion to be selected for redemption. The Notes (or portions thereof) so selected shall be deemed duly selected for redemption for all purposes hereof, notwithstanding that any such Note is submitted for conversion in part before the mailing of the notice of redemption.

          Upon any redemption of less than all of the outstanding Notes, the Company and the Trustee may (but need not), solely for purposes of determining the pro rata allocation among such Notes as are unconverted and outstanding at the time of redemption, treat as outstanding any Notes surrendered for conversion during the period of fifteen (15) days next preceding the mailing of a notice of redemption and may (but need not) treat as outstanding any Note authenticated and delivered during such period in exchange for the unconverted portion of any Note converted in part during such period.

          Section 3.03. Payment of Notes Called for Redemption by the Company. If notice of redemption has been given as provided in Section 3.02, the Notes or portion of Notes with respect to which such notice has been given shall, unless converted pursuant to the terms hereof, become due and payable on the date fixed for redemption and at the place or places stated in such notice at the applicable redemption price, together with interest accrued to (but excluding) the redemption date, and on and after said date (unless the Company shall default in the payment of such Notes at the redemption price, together with interest accrued to said date) interest on the Notes or portion of Notes so called for redemption shall cease to accrue and, after the close of business on the Business Day immediately preceding the redemption date, such Notes shall cease to be convertible and, except as provided in Sections 7.06 and 12.04, to be entitled to any benefit or security under this Indenture, and the holders thereof shall have no right in respect of such Notes except the right to receive the redemption price thereof and unpaid interest to (but excluding) the redemption date. On presentation and surrender of such Notes at a place of payment in said notice specified, the said Notes or the specified portions thereof shall be paid and redeemed by the Company at the applicable redemption price, together with interest accrued thereon to, but excluding, the redemption date; provided that if the applicable redemption date is an interest payment date, the interest payable on such interest payment date shall be payable to the holders of record of such Notes on the applicable record date instead of the holders surrendering such Notes for redemption on such date.

          Upon presentation of any Note redeemed in part only, the Company shall execute and the Trustee shall authenticate and make available for delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in principal amount equal to the unredeemed portion of the Notes so presented.

21

          Notwithstanding the foregoing, the Trustee shall not redeem any Notes or mail any notice of redemption during the continuance of a default in payment of interest or premium, if any, on the Notes. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium, if any, shall, until paid or duly provided for, bear interest from the redemption date at a rate equal to 1% per annum plus the rate borne by the Note (without duplication of the 1% increase provided for under Section 6.02) and such Note shall remain convertible into Common Stock or cash until the principal and premium, if any, and interest shall have been paid or duly provided for.

          Section 3.04. Conversion Arrangement on Call for Redemption. In connection with any redemption of Notes, the Company may arrange for the purchase and conversion of any Notes by an agreement with one or more investment banks or other purchasers to purchase such Notes by paying to the Trustee in trust for the Noteholders, on or before the date fixed for redemption, an amount not less than the applicable redemption price, together with interest accrued to, but excluding, the date fixed for redemption, of such Notes. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the redemption price of such Notes, together with interest accrued to, but excluding, the date fixed for redemption, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, a copy of which will be filed with the Trustee prior to the date fixed for redemption, any Notes not duly surrendered for conversion by the holders thereof may, at the option of the Company, 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 14) surrendered by such purchasers for conversion, all as of immediately prior to the close of business on the date fixed for redemption (and the right to convert any such Notes shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such amount paid to it in the same manner as it would monies deposited with it by the Company for the redemption of Notes. Without the Trustee’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Notes shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture.

          Section 3.05. Redemption at Option of Holders upon a Designated Event. (a) If there shall occur a Designated Event at any time prior to maturity of the Notes, then each Noteholder shall have the right, at such holder’s option, to require the Company to redeem all of such holder’s Notes, or any portion thereof that is a multiple of $1,000 principal amount, on the date (the “Designated Event Redemption Date”) that is thirty (30) days after the date of the Designated Event Notice (as defined in Section 3.05(b)) of such Designated Event (or, if such 30th day is not a Business Day, the next succeeding Business Day) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest to, but excluding, the Designated Event Redemption Date; provided that if such Designated Event Redemption Date is an interest payment date, then the interest payable on such interest payment date shall be paid to the holders of record of the Notes on the applicable record date instead of the holders surrendering the Notes for redemption on such date.

          Upon presentation of any Note redeemed in part only, the Company shall execute and, upon the Company’s written direction to the Trustee, the Trustee shall authenticate and

make available for delivery to the holder thereof, at the expense of the Company, a new Note or Notes, of authorized denominations, in aggregate principal amount equal to the unredeemed portion of the Note presented.

          (b) On or before the tenth day after the occurrence of a Designated Event, the Company or at its written request (which must be received by the Trustee at least five (5) Business Days prior to the date the Trustee is requested to give notice as described below, unless the Trustee shall agree in writing to a shorter period), the Trustee, in the name of and at the expense of the Company, shall mail or cause to be mailed to all holders of record on the date of the Designated Event a notice (the “Designated Event Notice”) of the occurrence of such Designated Event and of the redemption right at the option of the holders arising as a result thereof. Such notice shall be mailed in the manner and with the effect set forth in the first paragraph of Section 3.02 (without regard for the time limits set forth therein). If the Company shall give such notice, the Company shall also deliver a copy of the Designated Event Notice to the Trustee at such time as it is mailed to Noteholders. Concurrently with the mailing of any Designated Event Notice, the Company shall issue a press release announcing such Designated Event referred to in the Designated Event Notice, the form and content of which press release shall be determined by the Company in its sole discretion. The failure to issue any such press release or any defect therein shall not affect the validity of the Designated Event Notice or any proceedings for the redemption of any Note which any Noteholder may elect to have the Company redeem as provided in this Section 3.05.

          Each Designated Event Notice shall specify the circumstances constituting the Designated Event, the Designated Event Redemption Date, the price at which the Company shall be obligated to redeem Notes, that the holder must exercise the redemption right on or prior to the close of business on the Designated Event Redemption Date (the “Designated Event Expiration Time”), that the holder shall have the right to withdraw any Notes surrendered prior to the Designated Event Expiration Time, a description of the procedure which a Noteholder must follow to exercise such redemption right and to withdraw any surrendered Notes, the place or places where the holder is to surrender such holder’s Notes, the amount of interest accrued on each Note to (but excluding) the Designated Event Redemption Date and the CUSIP number or numbers of the Notes (if then generally in use).

          No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ redemption rights or affect the validity of the proceedings for the redemption of the Notes pursuant to this Section 3.05.

          (c) For a Note, other than a Global Note, to be so redeemed at the option of the holder, the Company must receive at the office or agency of the Company maintained for that purpose pursuant to Section 4.02, such Note with the form entitled “Option to Elect Repayment Upon A Designated Event” on the reverse thereof duly completed and signed, together with such Notes duly endorsed for transfer, on or before the Designated Event Expiration Time. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for redemption shall be determined by the Company, whose determination shall be final and binding absent manifest error.

23

          (d) On or prior to the Designated Event Redemption Date, the Company will deposit with the Trustee or with one or more paying agents (or, if the Company is acting as the paying agent, set aside, segregate and hold in trust as provided in Section 4.04) an amount of money sufficient to redeem on the Designated Event Redemption Date all the Notes to be redeemed on such date at the appropriate redemption price, together with accrued interest to, but excluding, the Designated Event Redemption Date; provided that if such payment is made on the Designated Event Redemption Date it must be received by the Trustee or paying agent, as the case may be, by 10:00 a.m. New York City time, on such date. Payment for Notes surrendered for redemption (and not withdrawn) prior to the Designated Event Expiration Time will be made promptly (but in no event more than five (5) Business Days) following the Designated Event Redemption Date by mailing checks for the amount payable to the holders of such Notes entitled thereto as they shall appear in the Note register.

          (e) In the case of a reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance to which Section 14.07 applies, in which the Common Stock of the Company is changed or exchanged as a result into the right to receive stock, securities or other property or assets (including cash), which includes shares of Common Stock of the Company or shares of common stock of another Person that are, or upon issuance will be, traded on a United States national securities exchange or approved for trading on an established automated over-the-counter trading market in the United States and such shares constitute at the time such change or exchange becomes effective in excess of 50% of the aggregate fair market value of such stock, securities or other property or assets (including cash) (as determined by the Company, which determination shall be conclusive and binding), then the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture (accompanied by an Opinion of Counsel that such supplemental indenture complies with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) modifying the provisions of this Indenture relating to the right of holders of the Notes to cause the Company to repurchase the Notes following a Designated Event, including without limitation the applicable provisions of this Section 3.05 and the definitions of Common Stock and Designated Event, as appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions apply to such other Person if different from the Company and the common stock issued by such Person (in lieu of the Company and the Common Stock of the Company).

          (f) The Company will comply with the provisions of Rule 13e-4 and any other tender offer rules under the Exchange Act to the extent then applicable in connection with the redemption rights of the holders of Notes in the event of a Designated Event.

     (b) delivery or book-entry transfer of the Notes to the Trustee (or other paying agent appointed by the Company) at any time after delivery of the applicable Repurchase Notice (together with all necessary endorsements) at the Corporate Trust Office (or the office of another paying agent appointed by the Company), such delivery being a condition to receipt by the holder of the purchase price therefor; provided that such purchase price shall be so paid pursuant to this Section 3.06 only if the Note so delivered to the Trustee (or other paying agent appointed by the Company) shall conform in all respects to the description thereof in the related Repurchase Notice.

          The Company shall purchase from the holder thereof, pursuant to this Section 3.06, a portion of a Note, 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 Note also apply to the purchase of such portion of such Note.

Such purchase price shall be paid to such holder, subject to receipt of funds and/or Notes by the Trustee at its Corporate Trust Office (or the office of another paying agent appointed by the Company), promptly following the later of (x) the Repurchase Date with respect to such Note (provided the holder has satisfied the conditions in Section 3.06) and (y) the time of delivery of such Note to the Trustee (or other paying agent

          Section 4.07. Payment of Taxes and Other Claims. The Company will pay or discharge, or cause to be paid or discharged, before the same may become delinquent, (i) all taxes, assessments and governmental charges levied or imposed upon the Company or any of its Subsidiaries or upon the income, profits or property of the Company or any of its Subsidiaries, (ii) all claims for labor, materials and supplies which, if unpaid, might by law become a lien or charge upon the property of the Company or any of its Subsidiaries and (iii) all stamp taxes and other duties, if any, which may be imposed by the United States or any political subdivision thereof or therein in connection with the issuance, transfer, exchange, conversion, redemption or repurchase of any Notes or with respect to this Indenture; provided that, in the case of clauses (i) and (ii), the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith and for which adequate reserves have been established in accordance with generally accepted accounting principles and which if unpaid would reasonably not be expected to result in a material adverse effect on the business, results of operations, or financial condition of the Company and its Subsidiaries, taken as a whole.

Upon the request of any holder or any beneficial holder of the Notes or such Common Stock, the Company will deliver to such holder a written statement as to whether it has complied with such requirements.

     (d) a default or defaults under the terms of any bond(s), debenture(s), note(s) or other evidence(s) of, or under any mortgage(s), indenture(s), agreement(s) or instrument(s) under which there may be issued or by which there may be secured or evidenced, any indebtedness of the Company or any of its Subsidiaries with a principal amount then outstanding, individually or in the aggregate, of at least $10,000,000, whether such indebtedness now exists or is hereafter incurred, which default or defaults (i) shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable or (ii) shall constitute the failure to pay such indebtedness at the final stated maturity thereof (after expiration of any applicable grace period) and such default shall not have been rescinded or such indebtedness shall not have been discharged within 10 days; or

     (e) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of the property of the Company, or ordering the winding up or liquidation of the affairs of the Company, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or

     (f) the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company to the entry of a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company or the filing by the Company of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by the Company to the filing of such a petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of the property of the Company, or the making by the Company of an assignment for the benefit of creditors, or the admission by the Company in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action;

then, and in each and every such case (other than an Event of Default specified in 6.01(e) or 6.01(f) that occurs with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding hereunder determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by Noteholders) specifying the respective Event of Default and stating that it is a “notice of acceleration”, may declare the principal of and premium, if any, on all the Notes and

34

the interest accrued thereon to be due and payable immediately, and upon receipt of such notice the same shall become and shall be immediately due and payable. If an Event of Default specified in 6.01(e) or 6.01(f) involving the Company occurs, the principal of all the Notes and the interest accrued thereon shall be immediately and automatically due and payable without necessity of further action. This provision, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all Notes and the principal of, and premium, if any on any and all Notes which shall have become due otherwise than by acceleration (with interest on overdue installments of interest (to the extent that payment of such interest is enforceable under applicable law) and on such principal and premium, if any, at the rate borne by the Notes plus 1%, to the date of such payment or deposit) and amounts due to the Trustee pursuant to Section 7.07, and if any and all defaults under this Indenture, other than the nonpayment of principal of, and premium, if any, and accrued interest on, Notes which shall have become due by acceleration, shall have been cured or waived pursuant to Section 6.07, then and in every such case the holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or Event of Default, or shall impair any right consequent thereon. In accordance with Section 4.10, the Company shall notify in writing a Responsible Officer of the Trustee, promptly upon becoming aware thereof, of any Event of Default or any event which, with notice or the lapse of time or both, would constitute an Event of Default.

          In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the holders of Notes, and the Trustee shall continue as though no such proceeding had been taken.

          Section 6.02. Payments of Notes on Default; Suit Therefor. The Company covenants that (a) in case default shall be made in the payment of any installment of interest upon any of the Notes as and when the same shall become due and payable, and such default shall have continued for a period of thirty (30) days, or (b) in case default shall be made in the payment of the principal of or premium, if any, on any of the Notes as and when the same shall have become due and payable, whether at maturity of the Notes or in connection with any redemption or repurchase, by or under this Indenture or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Notes, the whole amount that then shall have become due and payable on all such Notes for principal, premium, if any, or interest, as the case may be, with interest upon the overdue principal and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) upon the overdue installments of interest at the rate borne by the Notes, plus 1% and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including reasonable compensation to the Trustee, its agents, attorneys and counsel,

35

and all other amounts due the Trustee under Section 7.07. Until such demand by the Trustee, the Company may pay the principal of, and premium, if any, and interest on, the Notes to the registered holders, whether or not the Notes are overdue.

          In case the Company shall fail forthwith to pay such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on the Notes and collect in the manner provided by law out of the property of the Company or any other obligor on the Notes wherever situated the monies adjudged or decreed to be payable.

          In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the case of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest owing and unpaid in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee, its agents and its counsel and of the Noteholders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due the Trustee under Section 7.07, and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Noteholders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including counsel fees and expenses incurred by it up to the date of such distribution.

          All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the holders of the Notes.

          In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee

36

shall be held to represent all the holders of the Notes, and it shall not be necessary to make any holders of the Notes parties to any such proceedings.

          Section 6.03. Application of Monies Collected by Trustee. Any monies or other compensation collected by the Trustee pursuant to this Article 6 shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such monies or other compensation, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

     FIRST: To the payment of all amounts due the Trustee under Section 7.07;

     SECOND: In case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on the Notes in default in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by the Trustee) upon the overdue installments of interest at the rate borne by the Notes plus 1%, such payments to be made ratably to the Persons entitled thereto;

     THIRD: In case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount then owing and unpaid upon the Notes for principal and premium, if any, and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate borne by the Notes plus 1% to the Persons entitled thereto, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal, premium, if any, and interest without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal and premium, if any, and accrued and unpaid interest; and

     FOURTH: To the payment of the remainder, if any, to the Company or any other Person lawfully entitled thereto.

          Section 6.04. Proceedings by Noteholder. No holder of any Note shall have any right by virtue of or by reference to any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, and unless also the holders of not less than twenty-five percent (25%) in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for sixty (60) days after its receipt of such notice, request and

37

offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.07; it being understood and intended, and being expressly covenanted by the taker and holder of every Note with every other taker and holder and the Trustee, that no one or more holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights of any other holder of Notes, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Notes (except as otherwise provided herein). For the protection and enforcement of this Section 6.04, each and every Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

          Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any holder of any Note to receive payment of the principal of, and premium, if any (including the redemption or repurchase price upon redemption or repurchase pursuant to Article 3), and accrued interest on, such Note, on or after the respective due dates expressed in such Note or in the case of a redemption or repurchase, on the redemption date or Repurchase Date, as the case may be, or to institute suit for the enforcement of any such payment on or after such respective dates against the Company shall not be impaired or affected without the consent of such holder.

          Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any Note, without the consent of either the Trustee or the holder of any other Note, in its own behalf and for its own benefit, may enforce, and may institute and maintain any proceeding suitable to enforce, its rights of conversion as provided herein.

          Section 6.05. Proceedings by Trustee. In case of an Event of Default, the Trustee may, in its discretion, but shall not be required to, proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

          Section 6.06. Remedies Cumulative and Continuing. Except as provided in Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Noteholders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power and remedy given by this Article 6 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

38

          Section 6.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee; provided that (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action which is not inconsistent with such direction and (c) the Trustee may decline to take any action that the Trustee determines in its reasonable discretion would benefit some Noteholder to the detriment of other Noteholders or of the Trustee. The holders of a majority in aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 may, on behalf of the holders of all of the Notes, waive any past or existing default or Event of Default hereunder and its consequences except (i) a past or existing default in the payment of interest or premium, if any, on, or the principal of, the Notes (including in connection with an offer to purchase); provided however that holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration in accordance with Section 6.01, (ii) a failure by the Company to convert any Notes into Common Stock, cash or a combination of cash and Common Stock, (iii) a default in the payment of the redemption price pursuant to Article 3, (iv) a default in the payment of the purchase price pursuant to Article 3 or (v) a default in respect of a covenant or provisions hereof which under Article 10 cannot be modified or amended without the consent of the holders of each or all Notes then outstanding or affected thereby. Upon any such waiver, the Company, the Trustee and the holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been cured or waived as permitted by this Section 6.07, said default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

          Section 6.08. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by his acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.08 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Noteholder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any Note on or after the due date expressed in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article 14.

          When the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 6.01(e) or 6.01(f), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency or other similar law.

          Section 7.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall

          (f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all holders in the manner provided in Section 15.03. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office.

          (g) Notwithstanding replacement of the Trustee pursuant to this Section 7.10, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

          Section 7.11. Acceptance of Appointment of Successor. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on written request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts.

          No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article 7.

          Upon acceptance of appointment by a successor Trustee as provided in this Section 7.11, the Company (or the former Trustee, at the written direction of the Company) shall mail or cause to be mailed notice of the succession of such Trustee hereunder to the holders of Notes at their addresses as they shall appear on the Note register, which notice shall include the address of the Corporate Trust Office of such successor Trustee. If the Company fails to mail

44

such notice within ten (10) days after acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the Company.

          Section 7.12. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article 7, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

          Section 7.13. Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company or any other obligor upon the Notes, the Trustee shall be subject to the provisions of the Trust Indenture Act (as if such Act applied) regarding the collection of the claims against the Company or any such other obligor.

ARTICLE VIII

          Section 8.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record of the holders of Notes voting in favor thereof at any meeting of Noteholders duly called and held in accordance with the provisions of Article 9, or (c) by a combination of such instrument or instruments and any such record of such a meeting of Noteholders. Whenever the Company or the Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee may fix in advance of such solicitation, a date as the record date for determining holders entitled to take such action. The record date shall be not more than fifteen (15) days prior to the date of commencement of initial solicitation of such action without giving effect to any extension or amendment of such action or solicitation.

          Section 8.02. Proof of Execution by Noteholders. Subject to the provisions of Sections 7.03 and 9.05, proof of the execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note registrar.

45

          The record of any Noteholders’ meeting shall be proved in the manner provided in Section 9.06.

          Section 8.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any paying agent, any Conversion Agent and any Note registrar may deem the Person in whose name such Note shall be registered upon the Note register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Company or any Note registrar) for the purpose of receiving payment of or on account of the principal of, and premium, if any, and interest on, such Note, for conversion of such Note and for all other purposes; and neither the Company nor the Trustee nor any authenticating agent, any paying agent nor any Conversion Agent nor any Note registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being, or upon his order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Note.

          Section 8.04. Company-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent, waiver or other action under this Indenture, Notes which are owned by the Company or any other obligor on the Notes or any Affiliate of the Company or any other obligor on the Notes shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent, waiver or other action, only Notes which a Responsible Officer knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Company, any other obligor on the Notes or any Affiliate of the Company or any such other obligor. In the case of a dispute as to such right, any good faith decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Company to be owned or held by or for the account of any of the above described Persons, and, subject to Section 7.03, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

          Section 8.05. Revocation of Consents, Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any holder of a Note which is shown by the evidence to be included in the Notes the holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the holder of any Note shall be a continuing action and conclusive and binding upon such holder and upon all future holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor. An amendment,

46

supplement or waiver becomes effective in accordance with its terms and thereafter binds every holder.

          Section 9.02. Call of Meetings by Trustee. The Trustee may at any time call a meeting of Noteholders to take any action specified in Section 9.01, to be held at such time and at such place as the Trustee shall determine.

Such notice shall also be mailed to the Company. Such notices shall be mailed not less than twenty (20) nor more than ninety (90) days prior to the date fixed for the meeting.

          Any meeting of Noteholders shall be valid without notice if the holders of all Notes then outstanding are present in person or by proxy or if notice is waived before or after the meeting by the holders of all Notes outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice.

          Section 9.03. Call of Meetings by Company or Noteholders. In case at any time the Company, pursuant to a resolution of its Board of Directors, or the holders of at least twenty-five (25%) in aggregate principal amount of the Notes then outstanding, shall have requested the Trustee to call a meeting of Noteholders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within twenty (20) days after receipt of such request, then the Company or such Noteholders may determine the time and the place for such meeting and may

47

          The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Noteholders as provided in Section 9.03, in which case the Company or the Noteholders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the holders of a majority in principal amount of the Notes represented at the meeting and entitled to vote at the meeting except that any meeting called by the Company shall be chaired by a representative of the Company and any meeting called by the Trustee may, at the Trustee’s election, be chaired by the Trustee.

          Subject to the provisions of Section 8.04, at any meeting each Noteholder or proxyholder shall be entitled to one vote for each $1,000 principal amount of Notes held or represented by him. If any vote cast or counted or proposed to be cast or counted is challenged on the ground that such Note is not outstanding, or does not comply with the provisions of Section 9.04, the chairman of the meeting shall determine whether the holder of such Note is authorized to act. The chairman of the meeting shall have no right to vote other than by virtue of Notes held by him or instruments in writing as aforesaid duly designating him as the proxy to vote on behalf of other Noteholders. Any meeting of Noteholders duly called pursuant to the provisions of Section 9.02 or 10.02 may be adjourned from time to time by the holders of a majority of the aggregate principal amount of Notes represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

The permanent chairman of the meeting shall appoint two inspectors of votes who shall be representatives of the Trustee, and who shall count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in duplicate of all votes cast at the meeting. A record in

48

duplicate of the proceedings of each meeting of Noteholders shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was mailed as provided in Section 9.02. The record shall show the principal amount of the Notes voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

          Any record so signed and verified shall be conclusive evidence of the matters therein stated, absent manifest error.

          Section 9.07. No Delay of Rights by Meeting. Nothing contained in this Article 9 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Noteholders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Noteholders under any of the provisions of this Indenture or of the Notes.

     (i) during any fiscal quarter commencing after March 31, 2004, if the Closing Sale Price exceeds 120% of the Conversion Price for at least 20 Trading Days in the 30 consecutive Trading Day period ending on the last Trading Day of the immediately preceding fiscal quarter (it being understood for purposes of this Section 14.01(a)(i) that the Conversion Price in effect at the close of business on each of the 30 consecutive Trading Days should be used and such calculation shall give effect to any event referred to in Section 14.06 or 14.07 occurring during such 30 Trading Day period);

     (ii) during each of the five Business Day period immediately after any five consecutive Trading Day period in which the Trading Price per $1,000 principal amount of the Notes for each day of such five Trading Day period was less than 98% of the product of the Closing Sale Price on the applicable date and the Conversion Rate; provided, however, the Notes shall not be convertible pursuant to this Section 14.01(a)(ii) after February 1, 2029 if on any Trading Day during such five Trading Day period the Closing Sale Price was between 100% and 120% of the then current Conversion Price (it being understood for purposes of this Section 14.01(a)(ii) that the Conversion Rate in effect at the close of business on each of the five consecutive Trading Days should be used and such calculation shall give effect to any event referred to in Section 14.06 or 14.07 occurring during such five Trading Day period);

     (iii) if such Note has been called for redemption, at any time on or after the date the notice of redemption has been given until the close of business on the Business Day immediately preceding the redemption date; or

     (iv) as provided in Section (b) of this Section 14.01.

     Upon receipt by the Conversion Agent of a demand for conversion from a Noteholder pursuant to clause (i) of this Section, the Conversion Agent shall inform the Company of such request and the Company shall thereupon furnish to the Conversion Agent an Officer’s Certificate stating whether the Notes are then convertible pursuant to clause (i) of this Section and setting forth in reasonable detail the Company’s basis for such determination. Upon receipt of such Officer’s Certificate, if the Company has determined that the Notes are then convertible in accordance with clause (i) of this Section, the Conversion Agent shall, based solely on its review of the information contained in such Officer’s Certificate, confirm or refute the Company’s determination. If the Conversion Agent shall confirm that the Notes are then

55

convertible pursuant to clause (i) of this Section, then the Conversion Agent shall promptly deliver written notice thereof to the Company (and, if the Conversion Agent is other than the Trustee, to the Trustee). In any event, the Company shall be obligated at all times to determine whether the Notes shall be convertible as a result of the occurrence of an event specified in clause (i) of this Section. Whenever the Notes shall become convertible pursuant to this Section 14.01, the Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall notify the holders of the event triggering such convertibility in the manner provided in Section 15.03, and the Company shall also publicly announce such information and publish it on the Company’s web site. Any notice so given shall be conclusively presumed to have been duly given, whether or not the holder receives such notice.

          The Trustee (or other Conversion Agent appointed by the Company) shall have no obligation to determine the Trading Price under clause (ii) of this Section 14.01 unless the Company has requested such a determination; and the Company shall have no obligation to make such request unless a holder provides it with reasonable evidence that the Trading Price per $1,000 principal amount of Notes would be less than 98% of the product of the Closing Sale Price and the Conversion Rate. If such evidence is provided, the Company shall request that the Trustee (or other Conversion Agent) determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Closing Sale Price and the Conversion Rate.

           (b) In addition, if:

     (i) (A) the Company distributes to all holders of its Common Stock rights or warrants entitling them (for a period expiring within 45 days of the record date for the determination of the stockholders entitled to receive such distribution) to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Sale Price for the ten (10) Trading Days immediately preceding, but not including, the date such distribution is first publicly announced by the Company, or

     (B) the Company distributes to all holders of its Common Stock, assets (including cash), debt securities or rights to purchase its securities, where the Fair Market Value of such distribution per share of Common Stock exceeds 5% of the Closing Sale Price on the Trading Day immediately preceding the date such distribution is first publicly announced by the Company,

then, in either case, the Notes may be surrendered for conversion at any time on and after the date that the Company gives notice to the holders of such distribution, which shall be not less than 20 days prior to the Ex-Dividend Time for such distribution, until the earlier of the close of business on the Business Day immediately preceding, but not including, the Ex-Dividend Time or the date the Company publicly announces that such distribution will not take place; provided that no adjustment to the Conversion Rate or the ability of a holder of a Note to convert will be made if the holder will otherwise participate in such distribution without conversion; or

56

     (ii) the Company consolidates with, or merges with or into, another Person or is a party to a binding share exchange or conveys, transfers, sells, leases or otherwise disposes of all or substantially all of its properties and assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other property, then the Notes may be surrendered for conversion at any time from and after the date fifteen (15) days prior to the anticipated effective date of the transaction and ending on and including the date fifteen (15) days after the consummation of the transaction. The Board of Directors shall determine the anticipated effective date of the transaction, and such determination shall be conclusive and binding on the holders and shall be publicly announced by the Company and posted on its web site not later than two Business Day prior to such 15^th day.

          “Ex-Dividend Time” means, with respect to any distribution on shares of Common Stock, the first date on which the Common Stock trades, regular way, on the principal securities market on which the Common Stock are then traded without the right to receive such distribution.

          (c) A Note in respect of which a holder is electing to exercise its option to require redemption upon a Designated Event pursuant to Section 3.05(a) or repurchase pursuant to Section 3.06 may be converted only if such holder withdraws its election in accordance with Section 3.05(b) or Section 3.08, respectively. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder has converted his Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article 14.

          Section 14.02. Conversion Procedures. To convert a Note, a holder must (a) complete and manually sign the Conversion Notice or a facsimile of the Conversion Notice (a “Conversion Notice”) in the form set forth on the reverse of the Note and deliver such notice to the Conversion Agent, (b) surrender the Note to the Conversion Agent, (c) furnish appropriate endorsements and transfer documents if required by the Registrar or the Conversion Agent, (d) pay any transfer or similar tax, if required and (e) if required, pay funds equal to the interest payable on the next interest payment date. The date, within the time periods set forth in Section 14.01, on which the holder satisfies all of those requirements is the “Conversion Date.” Except as provided in Section 14.06(j), the Company shall deliver to the holder through the Conversion Agent, no later than the third Business Day following the Conversion Date, a certificate for the number of whole shares of Common Stock issuable upon the conversion and, if applicable, cash in lieu of any fractional shares pursuant to Section 14.04.

          In the case of a Global Note, the Conversion Notice shall be completed by a Depositary participant on behalf of the beneficial holder. Conversion Notices may be delivered and such Notes may be surrendered for conversion in accordance with the applicable procedures of the Depositary as in effect from time to time. In order to cause a Depositary participant to complete a Conversion Notice, a beneficial holder must complete, or cause to be completed, the appropriate instruction form for conversion pursuant to the Depositary’s book-entry conversion program. The Person in whose name the Common Stock certificate is registered shall be deemed to be a shareholder of record at the close of business on the applicable Conversion Date; provided, however, that if any such date is a date when the stock transfer books of the Company

57

are closed, such Person shall be deemed a shareholder of record as of the next date on which the stock transfer books of the Company are open.

          No payment or adjustment shall be made for dividends on, or other distributions with respect to, any Common Stock except as provided in this Article 14. On conversion of a Note, except for conversion during the period from the close of business on any record date immediately preceding any interest payment date to the close of business on the Business Day immediately preceding such interest payment date, in which case the holder on such record date shall receive the interest payable on such interest payment date, that portion of accrued and unpaid interest on the converted Note attributable to the period from the most recent interest payment date (or, if no interest payment date has occurred, from the date of original issuance of the Notes) through the Conversion Date 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 Note 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 accrued and unpaid interest 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 principal amount of the Note being converted pursuant to the provisions hereof.

          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 aggregate principal amount of Notes converted.

          Upon surrender of a Note that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the holder, a new Note equal in principal amount to the principal amount of the unconverted portion of the Note surrendered.

          Notes or portions thereof surrendered for conversion during the period from the close of business on any record date immediately preceding any interest payment date to the close of business on the Business Day immediately preceding such interest payment date shall be accompanied by payment to the Company or its order, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest payable on such interest payment date with respect to the principal amount of Notes or portions thereof being surrendered for conversion; provided that no such payment need be made if (1) the Company has specified a redemption date that occurs during the period from the close of business on a record date to the close of business on the Business Day immediately preceding the interest payment date to which such record date relates, (2) the Company has specified a Designated Event Redemption Date during such period or (3) any overdue interest exists on the Conversion Date with respect to the Notes converted, but only to the extent of overdue interest.

          Section 14.03. Payment Upon Conversion.

          (a) In the event that the Company receives notice of conversion on or prior to the Optional Redemption Notice Date or the day that is twenty (20) days prior to the maturity of the Notes (the “Final Notice Date”), the following procedures will apply:

58

          If the Company chooses to satisfy all or any portion of the Company’s obligation (the “Conversion Obligation”) in cash, the Company will notify the holder through the Trustee of the dollar amount to be satisfied in cash (which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) at any time on or before the date that is two Business Days following the conversion date (the “Cash Settlement Notice Period”). If the Company timely elects to pay cash for any portion of the shares otherwise issuable to such holder, the conversion notice may be retracted by the holder at any time during the two Business Day period beginning on the day after the final day of the Cash Settlement Notice Period (the “Conversion Retraction Period”); no such retraction can be made (and a conversion notice shall be irrevocable) if the Company does not elect to deliver cash in lieu of shares (other than cash in lieu of fractional shares). If the conversion notice has not been retracted, then settlement (in cash and/or shares) will occur on the Business Day following the final day of the twenty (20) Trading Day period beginning on the day after the final day of the Conversion Retraction Period (the “Cash Settlement Averaging Period”). Settlement amounts will be computed as follows:

     (i) If the Company elects to satisfy the entire Conversion Obligation in shares, the Company will deliver to holders surrendering Notes for conversion a number of shares equal to (1) the aggregate original principal amount of Notes to be converted divided by 1,000 multiplied by (2) the applicable Conversion Rate.

     (ii) If the Company elects to satisfy the entire Conversion Obligation in cash, the Company will deliver to holders surrendering Notes for conversion cash in an amount equal to the product of:

     (A) a number equal to (1) the aggregate original principal amount of Notes to be converted divided by 1,000 multiplied by (2) the Conversion Rate and

     (B) the average of the Closing Sale Price of the Common Stock during the Cash Settlement Averaging Period.

     (iii) If the Company elects to satisfy in cash a fixed portion of the Conversion Obligation other than the entire obligation, the Company will deliver to holders surrendering Notes for conversion such cash amount (“Cash Amount”) and a number of shares equal to the excess, if any, of the number of shares equal to (i) the aggregate original principal amount of Notes to be converted divided by 1,000, multiplied by (ii) the Conversion Rate, over the number of shares equal to the sum, for each day of the Cash Settlement Averaging Period, of (x) the Cash Amount, divided by the number of days in the Cash Settlement Averaging Period, divided by (y) the Closing Sale Price of the Common Stock. In addition, the Company will pay cash for all fractional shares of Common Stock based on the average Closing Sale Price of the Common Stock during the Cash Settlement Averaging Period.

     (iv) If the Company elects to satisfy the Conversion Obligation as described in subparagraphs (i) and (iii) above, and on the date the notice of

59

conversion is submitted by the holder, such holder’s Notes (x) have not been registered under the Securities Act or are not freely transferable pursuant to Rule 144(k) under the Securities Act and (y) the Company has not complied with the registration obligations provided in the Registration Rights Agreement, then the Company shall deliver to holders of such Notes an additional number of shares equal to 3% of the number of shares calculated under (i) and (iii) above.

     (b) In the event that the Company receives notice of conversion on an Optional Redemption Notice Date or the Final Notice Date, the Company will not send individual notices of its election to satisfy all or any portion of the Conversion Obligation in cash. Instead, if the Company chooses to redeem all or a portion of the Notes, the Company’s notice of redemption will inform the holders of its election to deliver shares of Common Stock or cash with respect to Notes converted prior to the redemption date. In addition, if the Company chooses to satisfy all or any portion of the Conversion Obligation with respect to conversions after the Final Notice Date in cash, the Company will send a single notice to the holders through the Trustee of the dollar amount to be satisfied in cash (which must be expressed either as 100% of the Conversion Obligation or as a fixed dollar amount) at any time on or before the Final Notice Date. Settlement amounts will be computed and settlement dates will be determined in the same manner as set forth under Section 14.03(a) above except that the “Cash Settlement Averaging Period” shall be the twenty (20) consecutive Trading Day period beginning on the Trading Day after the conversion date. If a conversion notice is received after an Optional Redemption Notice Date or the Final Notice Date, the holder of Notes subject to such conversion notice will not be allowed to retract the conversion notice. Settlement (in cash and/or shares) will occur on the Business Day following the final day of such Cash Settlement Averaging Period. If the Company does not elect to satisfy any part of the Conversion Obligation in cash (other than cash in lieu of any fractional shares), delivery of shares of Common Stock into which the Note are converted (and cash in lieu of any fractional shares) will be made through the Conversion Agent or the Depositary, as the case may be, as soon as practicable on or after the conversion date.

     (c) Notwithstanding anything to the contrary in this Indenture, at any time prior to maturity, the Company may irrevocably elect, in its sole discretion without the consent of the holders of the Notes, by notice to the Trustee and the holders of the Notes to satisfy in cash 100% of the principal amount of the Notes converted after the date of such election. After making such an election, the Company still may satisfy the remainder of the Conversion Obligation to the extent it exceeds the principal amount in cash or Common Stock or a combination of cash and Common Stock. If the Company chooses to satisfy all or a portion of the remainder of the Conversion Obligation in cash, the Company will provide notice of such election in the same manner as set forth above under either clause (a) or (b), whichever is applicable. If the Company chooses to satisfy all of the remainder of the Conversion Obligation in Common Stock, notice of the election to deliver cash for the principal amount will be deemed to have been provided on the last date of the Cash Settlement Notice Period and the notice of conversion will not be retractable. Settlement amounts will be computed and settlement dates will be determined in the same manner as set forth above under clause (a) or (b), as applicable.

          Section 14.04. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip certificates representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share of stock would be issuable upon the conversion of any Note or Notes, the Company shall make an adjustment and payment therefor in cash at the current market price thereof to the holder of Notes. For purposes of this Section 14.04, the “current market price” of a share of Common Stock shall be the Closing Sale Price on the last Business Day immediately preceding the day on which the Notes (or specified portions thereof) are deemed to have been converted.

          Section 14.05. Conversion Rate. Each $1,000 principal amount of the Notes shall be convertible into the number of shares of Common Stock specified in the form of Note (herein called the “Conversion Rate”) attached as Exhibit A hereto, subject to adjustment as provided in this Article 14.

          Section 14.06. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

     (a) In case the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the opening of business on the date following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution by a fraction,

     (i) the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for the determination of stockholders entitled to receive such dividend or other distribution plus the total number of shares of Common Stock constituting such dividend or other distribution; and

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination,

such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. If any dividend or distribution of the type described in this Section 14.06(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that 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 its outstanding shares of Common Stock entitling them (for a period expiring within forty-five (45) days after the date fixed for determination of stockholders entitled to receive such rights or warrants) to subscribe for or purchase shares of Common Stock at a

61

price per share less than the Average Market Price on the date such issuance is first publicly announced by the Company, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction,

     (i) the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the total number of additional shares of Common Stock offered for subscription or purchase, and

     (ii) the denominator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the number of shares that the aggregate offering price of the total number of shares so offered would purchase at such Average Market Price.

     Such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders 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 that 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 Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such issuance had not been so declared or made. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Average 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 and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

     (c) In case outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective.

     (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company or

62

evidences of its indebtedness or assets (including cash and securities, but excluding any rights or warrants referred to in Section 14.06(b), and excluding any dividend or distribution referred to in Section 14.06(a) (any of the foregoing hereinafter in this Section 14.06(d)) called the “Distribution”)), then, in each such case (unless the Company elects to reserve such Distribution for distribution to the Noteholders upon the conversion of the Notes so that any such holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount and kind of such Distribution which such holder would have received if such holder had converted its Notes immediately prior to the Record Date), the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect at the close of business on the Record Date with respect to such distribution by a fraction,

     (i) the numerator of which shall be the Average Market Price on such Record Date, and

     (ii) the denominator of which shall be the Average Market Price on such Record Date less (A) in the case of Distributions other than cash, the Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) on the Record Date of the portion of such Distributions applicable to one share of Common Stock and (B) in the case of Distributions of cash, the amount of such Distributions applicable to one share of Common Stock,

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided that if the then Fair Market Value (as so determined) of the portion of the Distribution so distributed applicable to one share of Common Stock is equal to or greater than the Average Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive upon conversion the amount of Distribution such holder would have received had such holder converted each Note on the Record Date. A holder who converts a Note pursuant to Section 14.01(b) shall not be entitled to any adjustment to the Conversion Rate with respect to such Note so converted. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 14.06(d) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Average Market Price on the applicable Record Date. Notwithstanding the foregoing, if the Distribution distributed by the Company to all holders of its Common Stock consists of capital stock of, or similar equity interests in, a Subsidiary or other business unit, the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction:

63

     (i) the numerator of which shall be the sum of (x) the average Closing Sale Price over the ten (10) consecutive Trading Day period (the “Spinoff Valuation Period") commencing on and including the fifth Trading Day after the date on which “ex-dividend trading” commences on the Common Stock on the Nasdaq National Market System or such other national or regional exchange or market on which the Common Stock is then listed or quoted and (y) the average Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) over the Spinoff Valuation Period of the portion of the Distribution so distributed applicable to one share of Common Stock; and

     (ii) the denominator of which shall be the average Closing Sale Price over the Spinoff Valuation Period,

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided that the Company may in lieu of the foregoing adjustment make adequate provision so that each Noteholder shall have the right to receive upon conversion the amount of Distribution such holder would have received had such holder converted each Note on the Record Date with respect to such distribution.

          Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.06 (and no adjustment to the Conversion Rate under this Section 14.06 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 14.06(d). If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders 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 was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 14.06 was made, (1) in the case of any such rights or warrants that 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 or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or

64

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 that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

          No adjustment of the Conversion Rate shall be made pursuant to this Section 14.06(d) in respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Company for distribution to holders of Notes upon conversion by such holders of Notes to Common Stock.

          For purposes of this Section 14.06(d) and Section 14.06(a) and (b), any dividend or distribution to which this Section 14.06(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of capital stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 14.06(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 14.06(a) and (b) with respect to such dividend or distribution shall then be made), except

     (A) the Record Date of such dividend or distribution shall be substituted as “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution”, “the date fixed for the determination of stockholders entitled to receive such rights or warrants” and “the date fixed for such determination” within the meaning of Section 14.06(a) and (b) and

     (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding at the close of business on the date fixed for such determination” within the meaning of Section 14.06(a).

     (e) (A) In case a tender or exchange offer made by the Company or any Subsidiary for all or any portion of the Common Stock (excluding any transactions solely involving odd lots of shares of Common Stock) shall expire and such tender or exchange offer (as amended upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that as of the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended) exceeds the Closing Sale Price on the Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Expiration Time by a fraction,

65

     (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged 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) at the Expiration Time and the Closing Sale Price on the Trading Day next succeeding the Expiration Time, and

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares (including Purchased Shares)) at the Expiration Time multiplied by the Closing Sale Price on the Trading Day next succeeding the Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day following the Expiration Time. If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made.

     (B) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount that increases the offeror’s ownership of Common Stock to more than 25% of the Common Stock outstanding and shall involve the payment by such Person of consideration per share of Common Stock having a Fair Market Value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) that as of the last time (the “Offer Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) exceeds the Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the Offer Expiration Time, and in which, as of the Offer Expiration Time, the Board of Directors is not recommending rejection of the offer, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the Offer Expiration Time by a fraction,

     (i) the numerator of which shall be the sum of (x) the Fair Market Value (determined as aforesaid) of the aggregate consideration payable to the stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Accepted Purchased Shares) at the Offer Expiration Time and the Closing Sale Price on the Trading Day next succeeding the Offer Expiration Time, and

66

     (ii) the denominator of which shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares (including Accepted Purchased Shares)) at the Offer Expiration Time multiplied by the Closing Sale Price on the Trading Day next succeeding the Offer Expiration Time,

such adjustment to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. If such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 14.06(e)(B) shall not be made if, as of the Offer Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 11 or a binding share exchange.

     (f) For purposes of this Section 14.06, the following terms shall have the meaning indicated:

     (1) “Average Market Price”, as of any date of determination, shall mean the average of the daily Closing Sale Prices for the ten (10) consecutive Trading Days immediately preceding (A) in the case of a determination pursuant to Section 14.06(b), the date such issuance or distribution is publicly announced and (B) otherwise, the earlier of such date of determination and the day before the “ex” date with respect to the issuance, distribution, subdivision or combination requiring such computation immediately prior to the date in question. For purpose of this paragraph, the term “ex” date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades, regular way, on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, and (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the time at which such subdivision or combination becomes effective.

          If another issuance, distribution, subdivision or combination to which Section 14.06 applies occurs during the period applicable for calculating “Average Market Price” pursuant to the definition in the preceding paragraph, “Average Market Price” shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Closing Sale Price during such period.

     (2) “Fair Market Value” shall mean the amount that a willing buyer would pay a willing seller in an arm’s-length transaction.

67

     (3) “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

     (g) The Company may make such increases in the Conversion Rate, in addition to those required by Section 14.06(a), (b), (c), (d) or (e) as the Board of Directors considers to be advisable to avoid or diminish any income tax to any 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 from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty (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 increased pursuant to the preceding sentence, the Company shall mail to holders of record of the Notes a notice of the increase at least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

     (h) All calculations under this Article 14 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities.

     (i) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the holder of each Note at his last address appearing on the Note register provided for in Section 2.05 of this Indenture, within twenty (20) days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

68

     (j) In any case in which this Section 14.06 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event (including without limitation, any event described in Section 14.06(d)), (2) the date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 14.06(a), (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to Section 14.06(b), or (4) the Expiration Time for any tender or exchange offer pursuant to Section 14.06(e), (each a “Determination Date”), the Company may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the holder of any Note converted after such Determination Date and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and (y) paying to such holder any amount in cash in lieu of any fraction pursuant to Section 14.04. For purposes of this Section 14.06(j), the term “Adjustment Event” shall mean:

     (i) in any case referred to in clause (1) hereof, the occurrence of such event,

     (ii) in any case referred to in clause (2) hereof, the date any such dividend or distribution is paid or made,

     (iii) in any case referred to in clause (3) hereof, the date of expiration of such rights or warrants, and

     (iv) in any case referred to in clause (4) hereof, the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable.

     (k) For purposes of this Section 14.06, 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 will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

     (l) To the extent the Notes become convertible to cash (other than Common Stock or securities to which Section 14.07 applies), no adjustment shall be made thereafter as to such cash. Interest shall not accrue on such cash.

          Section 14.07. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 14.06(c) applies), (ii) any consolidation, merger or combination of the Company with another Person as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, (iii) the Company is a party to a binding share exchange, or (iv) any sale or conveyance of all or

69

substantially all of the properties and assets of the Company to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, other 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 Person, 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, other securities or other 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 Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock are available to convert all such Notes) immediately prior to such reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance assuming such holder of Common Stock did not exercise his rights of election, if any, as to the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance (provided that, if the kind or amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance is not the same for each share of Common Stock in respect of which such rights of election shall not have been exercised (“nonelecting share”), then for the purposes of this Section 14.07 the kind and amount of stock, other securities or other property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, binding share exchange, sale or conveyance for each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares). Such supplemental indenture shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article 14.

          The Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Notes, at its address appearing on the Note register provided for in Section 2.05 of this Indenture, within twenty (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, sales and conveyances.

          Interest will not accrue on any cash into which the Notes are convertible.

          If this Section 14.07 applies to any event or occurrence, Section 14.06 shall not apply.

          Section 14.08. Taxes on Shares Issued. The issue of stock certificates on conversions of Notes shall be made without charge to the converting Noteholder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to

70

the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

          Section 14.09. Reservation of Shares, Shares to Be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes from time to time as such Notes are presented for conversion.

          Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate.

          The Company covenants that all shares of Common Stock which may be issued upon conversion of Notes will upon issue be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue by the Company thereof.

          The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued upon conversion, the Company will in good faith and as expeditiously as possible, to the extent then permitted by the rules and interpretations of the Commission (or any successor thereto), endeavor to secure such registration or approval, as the case may be.

          The Company further covenants that, if at any time the Common Stock shall be listed on the Nasdaq National Market or any other national securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Note; provided that if the rules of such exchange or automated quotation system permit the Company to defer the listing of such Common Stock until the first conversion of the Notes into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Notes in accordance with the requirements of such exchange or automated quotation system at such time.

          Section 14.10. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any holder of Notes to determine the Conversion Rate or 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. 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 Note; and the Trustee and any other Conversion Agent

71

make no representations with respect thereto. 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 Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 14. 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 Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Noteholders upon the conversion of their Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, 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 14.11. 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 15.05; or

     (b) the Company shall authorize the granting to the holders of all or substantially all of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants; or

     (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 stockholders 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;

the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his address appearing on the Note register provided for in Section 2.05 of this Indenture, as promptly as possible but in any event at least ten (10) 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 are to be determined, or (y) the date on which such reclassification, 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, 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

72

dividend, distribution, authorization, grant, reclassification, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

          Section 14.12. Rights Issued in Respect of Common Stock Issued upon Conversion. Each share of Common Stock issued upon conversion of Notes pursuant to this Article 14 shall be entitled to receive the appropriate number of common stock or preferred stock purchase rights, as the case may be (the “Rights”), if any, that shares of Common Stock are entitled to receive and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any shareholder rights agreement adopted by the Company, as the same may be amended from time to time (in each case, a “Rights Agreement”). Provided that such Rights Agreement requires that each share of Common Stock issued upon conversion of Notes at any time prior to the distribution of separate certificates representing the Rights be entitled to receive such Rights, then, notwithstanding anything else to the contrary in this Article 14 there shall not be any adjustment to the conversion privilege or Conversion Rate as a result of the issuance of Rights, but an adjustment to the Conversion Rate shall be made with respect to Notes then outstanding pursuant to Section 14.06(d) (to the extent required thereby) upon the separation of the Rights from the Common Stock.

73

          Any notice or communication mailed to a Noteholder shall be mailed to him by first class mail, postage prepaid, at his address as it appears on the Note register and shall be sufficiently given to him if so mailed within the time prescribed.

          Failure to mail a notice or communication to a Noteholder or any defect in it shall not affect its sufficiency with respect to other Noteholders. If a notice or communication is mailed in the manner provided above, it is duly given, whether or not the addressee receives it.

          Section 15.04. Governing Law. This Indenture and each Note shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of the State of New York without reference to its principles of conflict of laws.

          Section 15.06. Legal Holidays. In any case in which the date of maturity of interest on or principal of the Notes or the redemption date or Repurchase Date of any Note will not be a Business Day, then payment of such interest on or principal of the Notes need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date of maturity or the redemption date or Repurchase Date, and no interest shall accrue for the period from and after such date.

This Indenture is hereby made subject to, and shall be governed by, the provisions of the Trust Indenture Act required to be part of and to govern indentures qualified under the Trust Indenture Act; provided that unless otherwise required by law, notwithstanding the foregoing, this Indenture and the Notes issued hereunder shall not be subject to the provisions of subsections (a)(1), (a)(2), and (a)(3) of Section 314 of the Trust Indenture Act as now in effect or as hereafter amended or modified; provided further that this Section 15.07 shall not require this Indenture or the Trustee to be qualified under the Trust Indenture Act prior to the time such qualification is in fact required under the terms of the Trust Indenture Act, nor shall it constitute any admission or acknowledgment by any party to the Indenture that any such qualification is required prior to the time such qualification is in fact

          In case an Event of Default shall have occurred and be continuing, the principal of, and premium, if any, and accrued interest on, all Notes may be declared by either the Trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

          The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of at least a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Notes; provided that no such supplemental indenture shall (i) change the fixed maturity of any Note, or reduce the rate or change the time of payment of interest thereon, or reduce the principal amount thereof or premium, if any, thereon or reduce any amount payable on redemption or repurchase thereof, or impair the right of any Noteholder to institute suit for the payment thereof, or make the principal thereof or interest or premium, if any, thereon payable in any coin or currency or payable at any place other than that provided in the Indenture or the Notes, or change the obligation of the Company to redeem any Note on a redemption date in a manner adverse to the holders of Notes, or change the obligation of the Company to redeem any Note upon the happening of a Designated Event in a manner adverse to the holders of Notes, or change the obligation of the Company to repurchase any Note on a Repurchase Date in a manner adverse to the holders of Notes, or reduce the Conversion Rate otherwise than in accordance with the terms of the Indenture or otherwise impair the right to convert the Notes into Common Stock or cash subject to the terms set forth herein, including Section 14.07, thereof or reduce the quorum or the voting requirements under the Indenture, or modify any of the provisions of Section 10.02 or Section 6.07, except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each Note so affected, or change any obligation of the Company to maintain an office or agency in the places and for the purposes set forth in Section 4.01 thereof, in each case, without the consent of the holder of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the holders of which are required to consent to any such supplemental indenture or to waive any past Event of Default, without the consent of the holders of each Notes affected thereby.

Any such consent or waiver by the holder of this Note (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution hereof, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

          If a Designated Event occurs at any time prior to maturity of the Notes, this Note will be redeemable on a Designated Event Redemption Date, 30 days after notice thereof, at the option of the holder of this Note at a redemption price equal to 100% of the principal amount thereof, together with accrued interest to (but excluding) the redemption date; provided that if such Designated Event Redemption Date is a February 1 or August 1, the interest payable on such date shall be paid to the holder of record of this Note on the preceding January 15 or July 15, respectively.

The Company shall mail to all holders of record of the Notes a notice of the occurrence of a Designated Event and of the redemption right arising as a result thereof on or before the 10th day after the occurrence of such Designated Event. For a Note to be so redeemed at the option of the holder, the Company must receive at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, such Note with the form entitled “Option to Elect Repayment Upon a Designated Event” on the reverse thereof duly completed, together with such Note, duly endorsed for transfer, on or before the 30th day after the date of such notice of a Designated Event (or if such 30th day is not a Business Day, the immediately succeeding Business Day).

          Subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase, at the option of the holder, all or any portion of the Notes held by such holder on February 1, 2011, February 1, 2014, February 1, 2019, February 1, 2024 and February 1, 2029, in whole multiples of $1,000 at a purchase price of 100% of the principal amount, plus any accrued and unpaid interest, on such Note up to the Repurchase Date. As provided in Section 2.03 of the Indenture, if the Repurchase Date is an interest payment date, the semi-annual payment of interest becoming due on such date shall be payable to the holders of such Notes registered as such on the applicable record date. To exercise such right, a holder shall deliver to the Company such Note with the form entitled “Repurchase Notice” on the reverse thereof duly completed, together with the Note, duly endorsed for transfer, 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 the Repurchase Date, and shall deliver the Notes to the Trustee (or other paying agent appointed by the Company) as set forth in the Indenture.

          If cash sufficient to pay the purchase price of all Notes or portions thereof to be purchased as of the Repurchase Date is deposited with the Trustee (or other paying agent appointed by the Company), on the Business Day following the Repurchase Date, interest will cease to accrue on such Notes (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 purchase price upon surrender of such Note.

          Subject to the occurrence of certain events and in compliance with the provisions of the Indenture, the holder hereof has the right to convert each $1,000 principal amount of the Notes into 6.2610 shares of the Company’s Common Stock or a combination of shares of the Company’s Common Stock and cash, subject to adjustment as provided in the Indenture. A Note in respect of which a holder is exercising its right to require redemption upon a Designated Event

A-7

The Conversion Rate for the Notes on any Conversion Date shall be determined as set forth in the Indenture. The Company shall deliver cash or a check in lieu of any fractional share of Common Stock.

          The Company shall deliver to the holder through the Conversion Agent, no later than the third Business Day following the Conversion Date, a certificate for the number of whole shares of Common Stock issuable upon the conversion and, if applicable, cash in lieu of any fractional shares.

          A holder may convert a portion of a Note if the principal amount of such portion is $1,000 or an integral 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 a Note, except for conversion during the period from the close of business on any record date immediately preceding any interest payment date to the close of business on the Business Day immediately preceding such interest payment date, in which case the holder on such record date shall receive the interest payable on such interest payment date, that portion of accrued and unpaid interest on the converted Note attributable to the period from the most recent interest payment date (or, if no interest payment date has occurred, from the date of original issuance of the Notes) through the Conversion Date shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be paid in full to the holder thereof through delivery of the Common Stock (together with the cash payment, if any, in lieu of fractional shares), or cash in lieu thereof, in exchange for the Note being converted pursuant to the provisions hereof.

          Notes or portions thereof surrendered for conversion during the period from the close of business on any record date immediately preceding any interest payment date to the close of business on the Business Day immediately preceding such interest payment date shall be accompanied by payment to the Company or its order, in immediately available funds or other funds acceptable to the Company, of an amount equal to the interest payable on such interest payment date with respect to the principal amount of Notes or portions thereof being surrendered for conversion; provided that no such payment need be made if (1) the Company has specified a Redemption Date that occurs during the period from the close of business on a record date to the close of business on the Business Day immediately preceding the interest payment date to which such record date relates, (2) the Company has specified a Designated Event Redemption Date during such period or (3) only to the extent of overdue interest, any overdue interest exists on the Conversion Date with respect to the Notes converted.

          No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the current market price of the Common Stock as provided in Section 14.04 of the Indenture.

          To convert a Note, a holder must (a) complete and manually sign the conversion notice set forth below or a facsimile thereof and deliver such notice to a Conversion Agent, (b) surrender the Note 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, (d) pay any transfer or similar tax, if required and (e) if required pay funds equal to the interest payable on the next interest payment date.

A-8

          The Conversion Rate will be adjusted as set forth in Article 14 of the Indenture.

          Any Notes called for redemption, unless surrendered for conversion by the holders thereof on or before the close of business on the Business Day preceding the redemption date, may be deemed to be redeemed from the holders of such Notes for an amount equal to the applicable redemption price, together with accrued but unpaid interest to, but excluding, the date fixed for redemption, by one or more investment banks or other purchasers who may agree with the Company (i) to purchase such Notes from the holders thereof and convert them into shares of the Company’s Common Stock and (ii) to make payment for such Notes as aforesaid to the Trustee in trust for the holders.

          Upon due presentment for registration of transfer of this Note at the office or agency of the Company maintained for that purpose in accordance with the terms of the Indenture, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange thereof, subject to the limitations provided in the Indenture, without charge except for any tax, assessment or other governmental charge imposed in connection therewith.

          The Company, the Trustee, any authenticating agent, any paying agent, any Conversion Agent and any Note registrar may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon made by anyone other than the Company or any Note registrar) for the purpose of receiving payment hereof, or on account hereof, for the conversion hereof and for all other purposes, and neither the Company nor the Trustee nor any other authenticating agent nor any paying agent nor other Conversion Agent nor any Note registrar shall be affected by any notice to the contrary. All payments made to or upon the order of such registered holder shall, to the extent of the sum or sums paid, satisfy and discharge liability for monies payable on this Note.

          No recourse for the payment of the principal of, or any premium or interest on, this Note, or for any claim based hereon or otherwise in respect hereof, and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any supplemental indenture or in any Note, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or otherwise, all such liability being, by acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.
