Section 2.04 Payments of Additional Interest. If required by Section 4.02, each Note shall bear Additional Interest in the manner set forth herein. Whenever in this Supplemental Indenture there is mentioned, in any context, the payment of the principal of, premium, if any, or interest on, or in respect of, any Note, such mention shall be deemed to include mention of the payment of “Additional Interest” provided for in Section 4.02 to the extent that, in such context, Additional Interest is, was or would be payable in respect thereof and express mention of the payment of Additional Interest (if applicable) in any provisions hereof shall not be construed as excluding Additional Interest in those provisions hereof where such express mention is not made.

Section 2.05 Exchange and Registration of Transfer of Notes; Depositary.

(a) The Company shall cause to be kept at the corporate trust office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 3.02 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 transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby appointed “Note Registrar” and shall constitute a Registrar (as such term is defined in the Original Indenture) 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 3.02.

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 3.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Noteholder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for

conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 9 hereof.

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

(b) The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Notes. So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, all Notes shall be represented by one or more Notes in the form of Global Securities (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a definitive Note, shall be effected through the Depositary in accordance with this Supplemental Indenture and the procedures of the Depositary therefor.

Notwithstanding any other provisions of the Indenture (other than the provisions set forth in this Section 2.05(b)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to the Global Note. Initially, the Global Notes shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as Custodian for the Depositary.

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 calendar days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 calendar days or (iii) an Event of Default in respect of the Notes has occurred and is continuing, and any Noteholder has requested that the Notes be issued in definitive form in exchange for a Global Note, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and deliver Notes in definitive form to each person that the Depositary identifies as a beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be canceled.

Definitive Notes issued in exchange for all or a part of a Global Note pursuant to this Section 2.05(b) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive Notes to the Persons in whose names such definitive Notes are so registered.

At such time as all interests in a Global Note have been converted, canceled, redeemed, repurchased or transferred, such Global Note shall be, upon receipt thereof, 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 exchanged for definitive Notes, converted, canceled, repurchased or transferred to a transferee who receives definitive Notes therefor or any definitive Note is exchanged or transferred for part of such Global Note, 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 or increased, as the case may be, 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 or increase.

None of the Company, the Trustee, nor any agent of the Company or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 2.06 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 all notices issued to Noteholders as a convenience to holders of the Notes; 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 on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.07 Additional Notes; Repurchases. The Company may, without the consent of the Noteholders and notwithstanding Section 2.01, reopen this Supplemental Indenture and issue additional Notes hereunder with the same terms and with the same CUSIP number as the Notes initially issued hereunder in an unlimited aggregate principal amount, which will form the same series with the Notes initially issued hereunder; provided that no such additional Notes will be treated as part of the same series as the Notes unless such additional Notes will be part of the same issue as the Notes initially issued hereunder for U.S. federal income tax purposes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 11.05 of the Original Indenture, as the Trustee shall reasonably request. The Company may also from time to time repurchase the Notes in open market purchases or negotiated transactions without prior notice to Noteholders.

ARTICLE 3
Particular Covenants of the Company

Section 3.01 Payment of Principal, Premium and Interest. The Company covenants and agrees that it will cause to be paid the principal of and premium, if any (including the Fundamental Change Repurchase Price, the Repurchase Price and the Redemption Price), and accrued and unpaid interest on each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. Each installment of interest on the Notes, may be paid by mailing checks for the amount payable to Noteholders entitled thereto as they shall appear on the registry books of the Company; provided that, with respect to any Noteholder with an aggregate principal amount in excess of $1,000,000, at the application of such holder in writing to the Trustee and Paying Agent (if different from the Trustee) not later than the relevant Interest Record Date, interest on such holder’s Notes shall be paid by wire transfer in immediately available funds to such holder’s account in the United States, which application shall remain in effect until the Noteholder notifies the Trustee and Paying Agent to the contrary; provided further that payment of interest made to the Depositary shall be paid by wire transfer in immediately available funds in accordance with such wire transfer instructions and other procedures provided by the Depositary from time to time.

Section 3.02 Maintenance of Office or Agency. The Company will maintain in the United States, an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment, repurchase or redemption (“Paying Agent”) or for conversion (“Conversion Agent”) and where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the corporate trust office or the office or agency of the Trustee.

The Company may also from time to time designate as co-registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the United States, for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “Paying Agent” and “Conversion Agent” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian, Bid Solicitation Agent and Conversion Agent and the corporate trust office and the office or agency of the Trustee each shall be considered as one such office or agency of the Company for each of the aforesaid purposes; provided that the Trustee may appoint an agent, reasonably acceptable to the Company, to perform the duties of the Bid Solicitation Agent.

Section 3.03 Existence. Except as permitted by Section 7.01 or Article V of the Original Indenture, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 3.04 Additional Interest. If Additional Interest is payable by the Company, the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (a) the amount of such Additional Interest that is payable and (b) the date on which such interest is payable. Unless and until a Responsible Officer of the Trustee receives at the corporate trust office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable.

Section 3.05 Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Supplemental Indenture.

Section 3.06 Reporting Obligations. Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company will file with the Commission (unless the Commission will not accept such a filing) within the time periods specified in the Exchange Act and, within 15 days of filing, or attempting to file, the same with the Commission, furnish to the Trustee and the holders of the outstanding Notes:

(a) all quarterly and annual financial and other information with respect to the Company and its subsidiaries that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such forms, including a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report thereon by the Company’s certified independent accountants; and

(b) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports.

So long as the Company is required to file periodic reports under Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended, the Company’s obligation to deliver the information referred to above shall be deemed satisfied upon the filing of such information in the XXXXX system and the giving of notice to the Trustee as to the public availability of such information from such source.

Section 3.07 Future Guarantors. If any Subsidiary of the Company that is not a Subsidiary Guarantor guarantees or becomes a co-obligor with respect to any indebtedness for money borrowed of the Company or another Subsidiary Guarantor, then such Subsidiary shall, within 15 days thereof, execute a supplement to the Indenture under which it shall become a Subsidiary Guarantor with respect to the Notes in accordance with the terms of Article 10 hereof and Article X of the Original Indenture.

ARTICLE 4
Defaults and Remedies

Section 4.01 Additional Events of Default; Modifications. In addition to those Events of Default set forth in Section 6.01 of the Original Indenture, the following events shall be Events of Default with respect to the Notes and the terms of the Original Indenture shall be modified as set forth below:

(a) failure by the Company to issue a notice with respect to a Fundamental Change when such notice becomes due in accordance with Sections 8.03(d) or 9.02(b);

(b) failure by the Company to comply with its obligations to repurchase the Notes as required under Article 9, or failure by the Company to comply with its obligations to redeem the Notes under Article 10 after the Company issues a notice of redemption in accordance with Section 3.03 of the Original Indenture;

(c) failure by the Company to deliver when due of all cash and any shares of Common Stock or other consideration payable upon conversion with respect to the Notes, which failure continues for 10 days;

(d) failure by the Company to comply with Section 7.01 hereof upon our receipt of notice of such Default from the Trustee or from holders of not less than 25% in aggregate principal amount of the Notes then outstanding, and the failure to cure (or obtain a waiver of) such Default within 30 days after receipt of such notice;

(e) failure by any Subsidiary Guarantor to perform any covenant set forth in its Guarantee; and

(f) a default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any of its Subsidiaries (or the payment of which is guaranteed by the Company or any of its Subsidiaries), which default is caused by a failure to pay principal of or premium or interest on such indebtedness prior to the expiration of any grace period provided in such indebtedness, including any extension thereof (a “payment default”), or results in the acceleration of such indebtedness prior to its stated maturity and, in each case, the principal amount of any such indebtedness, together with the principal amount of any other such indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates in excess of $25.0 million and provided, further, that if any such default is cured or waived or any such acceleration rescinded, or such indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequential acceleration of the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree.

Section 4.02 Sole Remedy for Failure to Report. Notwithstanding any other provision of the Indenture, if the Company so elects, the sole remedy for an Event of Default relating to the failure to comply with the reporting obligations under Section 3.06 will, for the period beginning on the 91st calendar day after the written notice of the occurrence of such failure to report from the Trustee or holders of 25% of the outstanding principal amount of the Notes, consist exclusively of the right to receive additional interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes (the “Additional Interest”). This Additional Interest will be payable in the same manner and on the same dates as the stated interest payable on the Notes. If the Company so elects, this Additional Interest will accrue on all outstanding Notes from and including the 91st day following the date of such written notice of the failure to comply with Section 3.06 to but not including the date on which the Event of Default relating to

the reporting obligations as set forth in Section 3.06 shall have been cured or waived. On the 180th calendar day after the commencement of such Additional Interest (if such violation is not cured or waived prior to such 180th calendar day), the Notes will be subject to acceleration upon written notice from the Trustee or holders of 25% of the outstanding principal amount of the Notes, in accordance with Section 6.02 of the Original Indenture.

In order to exercise the extension right and elect to pay the Additional Interest as the sole remedy following the occurrence of any Event of Default relating to the failure to comply with Section 3.06 in accordance with the preceding paragraph, the Company must notify all Noteholders and the Trustee and Paying Agent of such election prior to the close of business on the 91st calendar day after the written notice to the Company of such failure to report (or, if such date is not a Business Day, on the first Business Day thereafter). Upon the Company’s failure to timely give such notice, the Notes will be subject to acceleration as provided above.

For the avoidance of doubt, the provisions of this Section 4.02 will not affect the rights of Noteholders in the event of the occurrence of any other Event of Default.

Section 4.03 Waivers of Certain Defaults. Section 6.04 of the Original Indenture is amended, for purposes of the Notes, to add after numbered clause (2) in the first sentence thereof, the following “or (3) a continuing Default or Event of Default in the delivery of cash, Common Stock or other consideration due upon conversion of any Security.”

ARTICLE 5
Optional Redemption of the Notes by the Company

Section 5.01 Optional Redemption.

(a) Subject to clause (b) below, on or after June 15, 2015, the Notes shall be redeemable, in whole or in part, at the option of the Company on any date specified by the Company in accordance with the Indenture (a “Redemption Date”), at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus any accrued and unpaid interest up to, but excluding, the Redemption Date (the “Redemption Price”); provided that if the Redemption Date is on a date that is after an Interest Record Date and on or prior to the corresponding Interest Payment Date, the Redemption Price shall be 100% of the principal amount of the Notes redeemed but shall not include accrued and unpaid interest, and the Company shall pay such interest on the Interest Payment Date to the Noteholder of record on the corresponding Interest Record Date. Notwithstanding the foregoing, the Company may not redeem the Notes on any date if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the relevant Redemption Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Redemption Price with respect to such Notes).

(b) The following provisions of the Original Indenture shall not apply with respect to the Notes: the last sentence of Section 3.02 of the Original Indenture, clause (8) of Section 3.04 of the Original Indenture, and the clause “unless the redemption or notice thereof is subject to one or more conditions as specified in the notice.” Except as otherwise provided herein, redemptions of the Notes shall be subject to Article III of the Original Indenture.

(c) If the Company calls the Notes for redemption, the Notes or portions of the Notes to be redeemed may be converted by the Noteholder until the close of business on the Business Day immediately preceding the Redemption Date in accordance with Article 8 hereof.

Section 5.02 Selection of Notes to Be Redeemed.

(a) If less than all of the Notes are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Notes to be redeemed by lot, on a pro rata basis, at random or by another method the Trustee considers fair and appropriate (so long as such method is not prohibited by the rules of any stock exchange or quotation association on which the Notes are then traded or quoted).

(b) Notes and portions of Notes that the Trustee selects shall be in principal amounts of $1,000 or an integral multiple of $1,000. Provisions of this Supplemental Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. The Trustee shall notify the Company promptly of the Notes or portions of the Notes selected to be redeemed and, in the case of any Notes selected for partial redemption, the method it has chosen for the selection of the Note.

(c) If any Note selected for partial redemption is converted in part before termination of the conversion right with respect to the portion of the Note so selected, the converted portion of such Note shall be deemed (so far as may be) to be the portion selected for redemption. Notes that have been converted during a selection of Notes to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection.

Section 5.03 Notice of Redemption. The Company shall notify each Noteholder of the redemption in the manner provided in Section 3.04 of the Original Indenture. In addition to those matters set forth in Section 3.04 of the Original Indenture, a notice of redemption sent to the Noteholders shall state:

(a) the name of the Paying Agent and Conversion Agent;

(b) the Base Conversion Rate;

(c) that the Notes called for redemption may be converted at any time prior to the close of business on the Business Day immediately preceding the Redemption Date;

(d) that Noteholders who wish to convert the Notes must comply with the procedures in Section 8.01 and Section 8.02; and

(e) in the event of the redemption of the Notes in part only, a new Note or Notes for the unredeemed portion will be issued in the name or names of the Noteholders thereof upon surrender thereof.

ARTICLE 6
Modifications and Amendments

“However, without the consent of the holder of each Note affected, an amendment, supplement or waiver under this Section 9.02 may not:

(a) alter the manner of calculation or rate of accrual of interest on the Note or change the time of payment of any installment of interest;

ARTICLE 7
Consolidation, Merger, Sale, Conveyance and Lease

Section 7.01 Company May Consolidate, Etc. on Certain Terms. Notwithstanding anything to the contrary in Section 5.01 of the Original Indenture, the Company shall not consolidate with or merge into any other Person or convey, transfer or lease all or substantially all of the Company’s properties and assets to any successor Person in a single transaction or series of related transactions, unless:

(a) either:

(i) the resulting, continuing, surviving or transferee Person is the Company; or

(ii) the resulting, continuing, surviving or transferee Person, if other than the Company, is organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia and shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all of the obligations of the Company under the Notes and the Indenture;

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and

(c) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that the transaction and such supplemental indenture comply with the Indenture.

Any reference in the Original Indenture to Section 5.01 therein shall, for the Notes, be deemed a reference to this Section 7.01.

ARTICLE 8
Conversion of Notes

Section 8.01 Right to Convert. (a) Subject to the provisions of this Article 8, on or prior to the close of business on the Business Day immediately preceding the Maturity Date, the Noteholders shall have the right, at such holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such holder’s Note into cash, and, if applicable, Common Stock as provided herein, unless such Notes have been previously redeemed or repurchased. The obligation of the Company to convert the Notes is referred to as the “Conversion Obligation.” A Noteholder’s right to convert a Note called for redemption will terminate at the close of business on the Business Day immediately preceding the Redemption Date for the Note, unless the Company defaults in making the payment due upon redemption. In addition, if a Noteholder has exercised its right to require the Company to repurchase its Notes under Article 9, such Noteholder may not convert its Notes unless it withdraws its repurchase notice prior to the close of business on the Business Day immediately preceding such Repurchase Date or Fundamental Change Repurchase Date, as applicable. The delivery to the Noteholder of the Settlement Amount together with any cash payment for such holder’s fractional shares, will be deemed to satisfy the Company’s obligation to pay the principal amount of the Notes and to satisfy the Company’s obligation to pay accrued and unpaid interest through the Conversion Date, except as provided in Section 8.02(i). Holders of Common Stock issued upon conversion, if any, will not be entitled to receive any dividends payable to holders of Common Stock as of a record date before the applicable Conversion Date.

Subject to the foregoing, prior to January 1, 2038, the Notes are convertible only in the circumstances described below in clauses (i)-(iv). On or after January 1, 2038, a Noteholder may surrender Notes for conversion at any time prior to the close of business on the Business Day immediately preceding the Maturity Date without regard to such conditions.

(i) Conversion Upon Satisfaction of Common Stock Price Condition. Notes may be converted during any calendar quarter commencing after June 30, 2008, and only during such quarter, if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the quarter immediately preceding such quarter (appropriately adjusted to take into account the occurrence, during such 30 consecutive Trading Days, of any event requiring adjustment of the Base Conversion Price under this Indenture) is more than 120% of the Base Conversion Price on such last Trading Day.

(ii) Conversion Upon Satisfaction of Trading Price Condition. Notes may be converted during the five consecutive Business Days after any five consecutive Trading Days on which the Trading Price of $1,000 principal amount of Notes, as determined by the Trustee following a request by a Noteholder in accordance with the procedures described below in Section 8.01(c), for each Trading Day of such five Trading Days was less than 97% of the product of the Last Reported Sale Price of the Common Stock for such Trading Day and the Applicable Daily Conversion Rate on such day.

(iii) Conversion Upon Notice of Redemption. A Note may be converted if such Note has been called for redemption by the Company pursuant to Section 3.01 and the redemption has not yet occurred, so long as the Noteholder surrenders such Note for conversion (or if the Note is held in book-entry form, completes and delivers to the Depositary appropriate instructions in accordance with the applicable procedures of the Depositary) after the notice of such redemption is given and prior to the close of business on the Business Day prior to the applicable Redemption Date (provided that if the Company shall default in paying the Redemption Price when due, the conversion right shall continue until such time as such default is cured and such Note is redeemed), whether or not the Note is otherwise convertible at such time.

(iv) Conversion Upon Specified Corporate Transactions.

A Note may be converted during the applicable time period specified below if:

(A) the Company makes a distribution to all or substantially all holders of Common Stock of rights, warrants or options entitling them (for a period commencing no earlier than the date of distribution and expiring not more than 45 calendar days after the Record Date of the distribution) to subscribe for or purchase shares of Common Stock at a price per share less than the average Last Reported Sale Prices of the Common Stock for the 10 Trading Days immediately preceding the date such distribution was first publicly announced;

(B) the Company makes a distribution to all or substantially all holders of Common Stock, of cash or other assets, debt securities, or rights or warrants to purchase the Company’s securities (other than those described in Section 8.04(a) or (b)), where the fair market value of such distribution per share of Common Stock (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value) exceeds 15% of the average of the Last Reported Sale Prices of the Common Stock for the ten Trading Days immediately preceding the date such distribution was first publicly announced;

(C) the Company is party to a consolidation, merger, share exchange, sale of all or substantially all of its assets or other similar transaction (in each case other than with one of the Company’s wholly-owned Subsidiaries), in each case pursuant to which the Common Stock would be converted into (or holders of Common Stock would be entitled to receive) cash, securities or other property; or

(D) a Make-Whole Fundamental Change occurs.

In the event of a distribution described in Sections 8.01(a)(iv)(A) and (B), the Company shall cause a written notice of such distribution to be given to the Trustee and the Conversion Agent and to be mailed to each Noteholder no later than 25 Trading Days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, Noteholders may surrender their Notes for conversion at any time thereafter until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date or the Company’s announcement that such distribution will not take place. If such distribution does not occur as

anticipated, the Company will issue a press release and notify the holders who have elected to convert their Notes promptly after the Company determines that such transaction will not occur and each such holder may elect to withdraw any then pending election to convert by a written notice of withdrawal delivered to the Conversion Agent within 10 Business Days (or longer period if required by law) after the Company makes such announcement. In such event, the Noteholders who do not make such a withdrawal election will receive the applicable Settlement Amount with respect to Notes surrendered for conversion three Trading Days following the later of (i) the end of the applicable Cash Settlement Averaging Period or (ii) the expiration of the 10 Business Day (or longer period if required by law) withdrawal period referred to above. No adjustment to the ability of Noteholders to convert will be made if the Noteholders are entitled to participate in a distribution without conversion.

In the event of a transaction described in Section 8.01(a)(iv)(C), the Company shall cause a written notice of such transaction to be given to the Trustee and the Conversion Agent and to each Noteholder no later than the date on which such transaction becomes effective. Once the Company has given such notice, Noteholders may surrender their Notes for conversion at any time from and including the Effective Date of such transaction until and including the date that is 30 calendar days after the Effective Date of such transaction.

In the event of a Make-Whole Fundamental Change, the Company shall give notice to the Trustee, the Conversion Agent and the Noteholders in accordance with the provisions of Section 8.03(d). Once the Company has given such notice, Noteholders may surrender their Notes for conversion at any time from and including the Effective Date of such transaction (or 15 Trading Days prior to the date the Company has announced as the anticipated Effective Date of the Make-Whole Fundamental Change if such event constitutes a Fundamental Change as described under clause (d) of the definition of Fundamental Change) until and including the Business Day immediately preceding the Fundamental Change Repurchase Date with respect to such transaction; provided, however, the Company will have no obligation to deliver any Settlement Amount in respect of any such conversion prior to the Effective Date of such Make-Whole Fundamental Change.

In the case of an event constituting a Fundamental Change as described under clause (d) of the definition of Fundamental Change, if the transaction does not occur, the Company will not be obligated to increase the Applicable Conversion Rate pursuant to Section 8.03 in connection with such transaction, regardless of the fact that holders may have elected to convert Notes in anticipation of the Effective Date of such event and the Company will issue a press release and notify the holders who have elected to convert their Notes promptly after the Company determines that such transaction will not occur and each such holder may elect to withdraw any then pending election to convert by a written notice of withdrawal delivered to the Conversion Agent within 10 Business Days (or longer period if required by law) after the Company makes such announcement. In such event, the Noteholders who do not make such a withdrawal election will receive the applicable Settlement Amount with respect to Notes surrendered for conversion three Trading Days following the later of (i) the end of the applicable Cash Settlement Averaging Period or (ii) the expiration of the 10 Business Day (or longer period if required by law) withdrawal period referred to above.

(b) For each fiscal quarter of the Company commencing prior to January 1, 2038, the Company shall determine, on the first Business Day following the last Trading Day of the immediately preceding quarter, whether the Notes are convertible pursuant to clause (i) of Section 8.01(a). If the conditions set forth in clause (i) of Section 8.01(a) have been met, the Company shall so notify the Trustee and mail to each Noteholder a written notice.

(c) The Trustee shall have no obligation to determine the Trading Price of the Notes pursuant to clause (ii) of Section 8.01(a) unless the Company has requested such determination in writing; and the Company shall have no obligation to make such request unless a Noteholder who holds at least $2,000,000 principal amount of Notes provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes is reasonably likely to be less than 97% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Daily Conversion Rate then in effect on such date. If a Noteholder provides such evidence or if the Company otherwise elects to require such determination, the Company shall instruct the Trustee to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price of the Notes is greater than or equal to 97% of the product of the Last Reported Sale price of the Common Stock and the Applicable Daily Conversion Rate on such date. The Trustee shall promptly notify the Company of its determination on each such day. If the condition set forth in clause (ii) of Section 8.01(a) has been met, the Company shall so notify the Noteholders.

(d) For purposes of clause (ii) of Section 8.01(a), if the Bid Solicitation Agent cannot reasonably obtain at least one bid for $5.0 million principal amount of Notes from an independent nationally recognized securities dealer on a Trading Day, then the Trading Price of Notes will be deemed to be less than 97% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Daily Conversion Rate for such Trading Day.

Section 8.02 Conversion Procedure; Payment Upon Conversion.

(a) Subject to this Section 8.02, the Company will satisfy the Conversion Obligation with respect to each $1,000 principal amount of Notes surrendered for conversion in cash and shares of fully paid Common Stock, if applicable, by delivering a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive Trading Days during the applicable Cash Settlement Averaging Period.

Except as otherwise provided herein, the Company shall deliver the Settlement Amount to the Noteholders who have surrendered Notes for conversion on the third Business Day immediately following the last day of the Cash Settlement Averaging Period in respect of such Notes.

The (i) Applicable Conversion Rate, (ii) cash component of the Settlement Amount, (iii) number of full shares of Common Stock, if any, to be delivered, and (iv) cash deliverable in lieu of fractional shares pursuant to Section 8.02(k), if any, shall be determined by the Company promptly following the last day of the Cash Settlement Averaging Period. Promptly after such determination, the Company shall provide written notice to the Trustee and the Conversion Agent of such determination. The Trustee and the Conversion Agent shall have no responsibility for any such determination.

(b) Before any holder of a Note shall be entitled to convert the same as set forth above, such holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 8.02(i) and, if required, all transfer or similar taxes, if any, as set forth Section 8.02(f) and (ii) in the case of a Note issued in certificated form, (1) complete and manually sign and deliver an irrevocable notice to the Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof) (Exhibit B hereto) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such holder wishes the certificate or certificates for the shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank, at the office of the Conversion Agent, (3) if required, pay funds equal to interest payable on the next Interest Payment Date to which such holder is not entitled as set forth in Section 8.02(i), (4) if required, furnish appropriate endorsements and transfer documents, and (5) if required, pay all transfer or similar taxes, if any, as set forth in Section 8.02(f). The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any conversion pursuant to this Article 8 on the date of such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a holder thereof if such holder has also delivered a Fundamental Change Repurchase Notice or Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice or Repurchase Notice, as the case may be, in accordance with Section 9.03.

If more than one Note shall be surrendered for conversion at one time by the same holder, the Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(c) Upon effectiveness of corporate transactions specified in Section 8.06, the Company will settle conversion with respect to such transactions as described above (based on the Applicable Conversion Rate as increased by the Additional Shares as set forth in Section 8.03, as applicable) on the later to occur of (i) the third Trading Day immediately following the Effective Date of the transaction and (ii) the third Trading Day following the last day of the applicable Cash Settlement Averaging Period; provided that, if the Reference Property consists entirely of cash or property other than publicly traded securities, the Company will deliver the Settlement Amounts to converting holders no later than the third Business Day after the date of determination of the value of such consideration, but no earlier than the third Trading Day immediately following the Effective Date of the transaction.

(d) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “Conversion Date”) that the holder has complied with the requirements set forth in Section 8.02(b) above. The payment of cash and delivery of shares of Common Stock, if any, and the payment of cash, if any, in lieu of fractional shares, pursuant to Section 8.02(a) in satisfaction of the Conversion Obligation shall be made by the Company in no event later than the date specified in Section 8.02(a) or 8.02(c) or elsewhere in this Supplemental Indenture by (i) payment of the cash comprising a portion of the Settlement Amount (including amounts of cash in lieu of the issuance of any fractional shares, if any), and (ii) by issuing or

causing to be issued, and delivering to the Conversion Agent or to such holder, or such holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock, if any, to which such holder shall be entitled as part of such Conversion Obligation.

(e) In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the holder of the Note so surrendered, without charge to such holder, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

(f) If a holder submits a Note for conversion, the Company shall pay all documentary, stamp or similar issue or transfer tax, if any, that may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Common Stock, upon the conversion. However, the holder shall pay any such tax that is due because the holder requests any such shares of Common Stock to be issued in a name other than the holder’s name. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to pay any tax that will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations.

(g) Except as provided in Section 8.04, no adjustment shall be made for dividends on any shares issued upon the conversion of any Note with a record date after the Conversion Date.

(h) Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

(i) If Notes are converted after the close of business on a Interest Record Date but prior to the open of business on the immediately following Interest Payment Date, holders of such Notes as of the close of business on the Interest Record Date will receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes, upon surrender for conversion during the period from the close of business on any Interest Record Date but prior to the open of business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of the interest payable on the Notes so converted; provided, however, that no such payment shall be required (1) if the Company has specified a Redemption Date or Fundamental Change Repurchase Date that is after an Interest Record Date but on or prior to the Business Day immediately following the related Interest Payment Date, (2) to the extent of any overdue interest, if any, existing at the time of conversion with respect to such Note or (3) if the Notes are surrendered for conversion after the close of business on the Interest Record Date immediately preceding the Maturity Date and before the close of business on the Business Day immediately preceding the Maturity Date. Except as described above, no payment or adjustment will be made for accrued and unpaid interest on converted Notes.

(j) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the applicable Conversion Date; provided, however, if such Conversion Date occurs on any date when the stock transfer books of the Company shall be closed, such occurrence shall not be effective to constitute the Person or Persons entitled to receive any such shares of Common Stock due upon conversion as the record holder or holders of such shares of Common Stock on such date, but such occurrence shall be effective to constitute the Person or Persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open. Upon conversion of Notes, such Person shall no longer be a Noteholder.

(k) No fractional shares of Common Stock or securities representing fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. Instead of any fractional share of Common Stock or securities representing fractional shares of Common Stock that would otherwise be issued upon conversion of any Note or Notes (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share), as determined by the Company, in an amount equal to the same fraction of the average of the Applicable Stock Prices on each Trading Day of the applicable Cash Settlement Averaging Period. For purposes of the foregoing, fractional shares arising from the calculation of the Daily Settlement Amount for any day in the Cash Settlement Averaging Period shall be aggregated with fractional shares for all other days in such period in determining the Settlement Amount, and any whole shares resulting therefrom shall be issued and any remaining fractional shares shall be paid in cash as provided herein. 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 issued upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered.

(l) When a Noteholder surrenders Notes for conversion, the Company may, at its election, direct, in writing, the Conversion Agent to surrender such Notes to a financial institution designated by the Company (the “Designated Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the Designated Institution must agree to deliver, in exchange for such Notes, cash and the number of shares of Common Stock, if any, due upon conversion based upon the Applicable Conversion Rate in full satisfaction of the Conversion Obligation, as determined pursuant to Section 8.02(a). If such an election is made, then by the close of business on the Scheduled Trading Day immediately preceding the start of the Cash Settlement Averaging Period, the Company will provide written notification to the Noteholder surrendering the Notes for conversion that it has directed the Designated Institution to make an exchange in lieu of conversion. If the Designated Institution accepts any such Notes, it will deliver the cash, and if any, the number of shares of Common Stock due upon conversion to the Conversion Agent, and the Conversion Agent will deliver such cash and shares of Common Stock to the converting Noteholder. Any Notes exchanged by the Designated Institution will remain outstanding. If the Designated Institution does not accept the Notes for exchange or agrees to accept any Notes for exchange but does not timely deliver the related cash and shares of Common Stock, the Company will, as promptly as practical thereafter (but in any event, no later than the fourth Trading Day immediately following the last Trading Day of the relevant Cash Settlement Averaging Period) convert the Notes as set forth under Section 8.02(a). The Company’s designation of a Designated Institution to which the Notes may

be submitted for exchange does not require the Designated Institution to accept any Notes. The Company will not pay any consideration to, or otherwise enter into any agreement with, the Designated Institution for or with respect to such designation.

Section 8.03 Increase of Conversion Rate Upon Conversion Upon Make-Whole Fundamental Changes. (a) If a Noteholder elects to convert Notes in connection with a Make-Whole Fundamental Change, then the Applicable Conversion Rate of the Notes being converted by such Noteholder shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) if any, as described herein. For purposes of this Section 8.03, any conversion of the Notes by a Noteholder will be deemed to be “in connection with” such Make-Whole Fundamental Change if it occurs during the period that begins on the Effective Date of such Make-Whole Fundamental Change (or 15 Trading Days prior to the date the Company has announced as the anticipated Effective Date of such Make-Whole Fundamental Change pursuant to clause (d) below if such event constitutes a Fundamental Change as described under clause (d) of the definition of Fundamental Change) and ends on (and includes) the Business Day prior to the Fundamental Change Repurchase Date relating to such Make-Whole Fundamental Change. In the case of a transaction described in clause (d) of the definition of Fundamental Change, if the transaction does not occur, the Company will not be obligated to increase the Applicable Conversion Rate in connection with such transaction, regardless of the fact that holders may have elected to convert Notes in anticipation of the effective date of such event, and the Company will issue a press release and notify the holders who have so elected to convert their Notes promptly after the Company determines that the transaction in question will not occur. Each such holder may then elect to withdraw any election to convert by a written notice of withdrawal delivered to the Conversion Agent within 10 Business Days after the Company announces that the transaction will not occur as anticipated (or longer period if required by applicable law).

The increase in the Applicable Conversion Rate in connection with a Make-Whole Fundamental Change, expressed as a number of Additional Shares, will be determined by the Company by reference to the table and adjustments thereto in Section 8.03(b), based on the Effective Date of the Make-Whole Fundamental Change and the applicable Stock Price. Any such increase in the Applicable Conversion Rate will be effected by adding to each of the Daily Conversion Rate Fractions 1/20^th of the applicable number of Additional Shares set forth in the tables in clause (b) below with respect to such Make-Whole Fundamental Change.

(b) The following tables set forth the Effective Date and number of Additional Shares by which the Applicable Conversion Rate will be increased upon a conversion in connection with a Make-Whole Fundamental Change that occurs in the corresponding period to be determined by reference to the Stock Price and Effective Date of the Make-Whole Fundamental Change:

provided, however, that:

(i) if the actual Stock Price of such Make-Whole Fundamental Change is between two Stock Prices listed in the tables above under the column titled “Stock Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the tables above in the row immediately below the title “Effective Date,” then the number of Additional Shares for such Make-Whole Fundamental Change shall be determined by the Company by a straight-line interpolation between the number of Additional Shares set forth for such higher and lower Stock Prices, or for such earlier and later Effective Dates based on a 365 day year, as applicable;

(ii) if the actual Stock Price of such Make-Whole Fundamental Change is greater than $170.00 per share (subject to adjustment in the same manner as the Stock Price as provided in clause (iii) below), or if the actual Stock Price of such Make-Whole Fundamental Change is less than $46.87per share (subject to adjustment in the same manner as the Stock Price as provided in clause (iii) below), then the number of Additional Shares shall be equal to zero and this Section 8.03 shall not require the Company to increase the Applicable Conversion Rate with respect to such Make-Whole Fundamental Change;

(iii) if an event occurs that requires, pursuant to Section 8.04, an adjustment to the Base Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each price set forth in the tables above under the row titled “Stock Price” shall be adjusted so that such Stock Price, at and after such time, shall be equal to the product of (1) such Stock Price as in effect immediately before such adjustment to such Stock Price and (2) a fraction whose numerator is the Base Conversion Rate in effect immediately before such adjustment to the Base Conversion Rate and whose denominator is the Base Conversion Rate to be in effect, in accordance with Section 8.04, immediately after such adjustment to the Base Conversion Rate; and

(iv) each number of Additional Shares set forth in the tables above shall be adjusted in the same manner in which, and for the same events for which, the Base Conversion Rate is to be adjusted pursuant to Section 8.04.

In no event will the Applicable Conversion Rate after adjustment described in this Section 8.03(b) exceed 21.3356 per $1,000 principal amount of Notes, subject to adjustments as set forth in Section 8.04.

(c) For the avoidance of doubt, the increases provided for in Section 8.03 shall only be made with respect to the Notes being converted in connection with such Make-Whole Fundamental Change and shall not be effective as to any Notes not so converted.

(d) As soon as practicable after the Company determines the anticipated Effective Date of any proposed Make-Whole Fundamental Change and no later than (i) the 15th Scheduled Trading Day prior to the date on which such Make-Whole Fundamental Change is anticipated to become effective in the case of a Make-Whole Fundamental Change described in clause (d) of the definition of Fundamental Change, or (ii) two Business Days after the Company learns of a Make-Whole Fundamental Change described in clause (a) of the definition of Fundamental Change, the Company shall provide written notice of such anticipated Effective Date to the Trustee and the Conversion Agent and mail a notice to each Noteholder, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the Company’s website, the anticipated Effective Date of such proposed Make-Whole Fundamental Change. Each such notice, press release notice, announcement and publication shall also state that in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Applicable Conversion Rate applicable to Notes entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Notes must be surrendered in order to be entitled to such increase). No later than the actual Effective

Date of each Make-Whole Fundamental Change, the Company shall provide written notice to the Trustee and the Conversion Agent and mail a notice to each Noteholder, and shall issue a press release indicating, and publicly announce, through a public medium that is customary for such announcements, and publish on the Company’s website, such Effective Date and the amount by which the Applicable Conversion Rate has been so increased.

Section 8.04 Adjustment of Base Conversion Rate. The Base Conversion Rate shall be adjusted from time to time by the Company as follows:

(a) In case the Company shall issue shares of Common Stock as a dividend or distribution on shares of Common Stock to all holders of the outstanding shares of Common Stock, or if the Company effects a share split or share combination, the Base Conversion Rate will be adjusted based on the following formula:

where,


CR₀	=	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as the case may be;

CR’	=	the new Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date of such share split or share combination, as the case may be;

OS₀	=	the number of outstanding shares of Common Stock immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as the case may be; and

OS’	=	the number of outstanding shares of Common Stock immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as the case may be, assuming, for this purpose only, the completion of such dividend, distribution, share split or share combination, as the case may be, immediately prior to the open of business on such date.

Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or the effective date for such share split or share combination. If any dividend or distribution of the type described in this Section 8.04(a) is declared but not so paid or made, or any split or combination of the type described in this Section 8.04(a) is announced but the outstanding shares of Common Stock are not split or

combined, as the case may be, the new Base Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or split or combine the outstanding shares of Common Stock, as the case may be, to the Base Conversion Rate that would then be in effect if such dividend or distribution had not been declared or such share split or share combination had not been announced.

(b) In case the Company shall distribute to all or substantially all holders of its Common Stock any rights or warrants entitling them for a period of not more than 45 calendar days after the Record Date of such distribution to subscribe for or purchase shares of the Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock on the 10 Trading Days immediately preceding the date that such distribution was first publicly announced, the Base Conversion Rate shall be adjusted based on the following formula:

where,


CR₀	=	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR’	=	the new Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;

OS₀	=	the number of outstanding shares of the Common Stock immediately prior to the open of business on the Ex-Dividend Date for such distribution;

X	=	the total number of shares of the Common Stock issuable pursuant to such rights or warrants; and

Y	=	the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights or warrants, divided by the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Days ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution of such rights or warrants.

Such adjustment shall be successively made whenever any such rights or warrants are distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that shares of the Common Stock are not delivered after the expiration of such rights or warrants, the Base Conversion Rate shall be readjusted to the Base 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 Base Conversion Rate shall again be adjusted to be the Base Conversion Rate that would then be in effect if such distribution had not been declared.

In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than the applicable Last Reported Sale Price of the Common Stock, and in determining the aggregate exercise price payable for such Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable upon exercise thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors. In no event shall the Base Conversion Rate be decreased pursuant to this Section 8.04(b), except for readjustments described above.

(c) In case the Company shall distribute shares of its capital stock, evidences of its indebtedness or other of its assets or property other than (i) dividends or distributions covered by Section 8.04(a) or Section 8.04(b), (ii) dividends or distributions paid exclusively in cash, and (iii) Spin-Offs to which the provisions set forth below in this Section 8.04(c) shall apply (any of such shares of capital stock, indebtedness, or other asset or property hereinafter in this Section 8.04(c) called the “Distributed Property”), to all or substantially all holders of its Common Stock, then, in each such case, the Base Conversion Rate shall be adjusted based on the following formula:

where,


CR₀	=	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR’	=	the new Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Days ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV	=	the fair market value (as determined by the Board of Directors) of the Distributed Property with respect to one share of the Common Stock on the Ex-Dividend Date for such distribution.

Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution; provided that if “FMV” as set forth above is equal to or greater than “SP₀” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall receive on the date on which the Distributed Property is distributed to holders of the Common Stock, for each $1,000 principal amount of Notes upon conversion, the amount of Distributed Property such holder would have received had such holder owned a number of shares of Common Stock equal to the Applicable Daily Conversion Rate on the Record Date for such distribution. Except as provided below, if the Board of Directors determines “FMV” for purposes of this Section 8.04(c) 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 Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Days ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

In lieu of the foregoing, with respect to an adjustment pursuant to this Section 8.04(c) where there has been a dividend or other distribution on the Common Stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company (a “Spin-Off”), the Base Conversion Rate will be increased based on the following formula:

where,


CR₀	=	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date of the Spin-Off;

CR’	=	the new Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date of the Spin-Off;

FMV	=	the average of the last reported sale prices of the capital stock or similar equity interest distributed to holders of the Common Stock on its principal trading market applicable to one share of the Common Stock over the 10 consecutive Trading Days immediately following, and including, the Ex-Dividend Date of the Spin-Off (the “Spin-Off Valuation Period”); and

MP₀		the average of the Last Reported Sale Prices of the Common Stock over the Spin-Off Valuation Period.

The adjustment to the Base Conversion Rate under the preceding paragraph will be deemed to be effective immediately after the open of business on the Ex-Dividend Date of the Spin-Off; provided that, for purposes of determining the Base Conversion Rate, in respect of any Trading Day during a Cash Settlement Averaging Period during a Spin-Off Valuation Period, references in the portion of this Section 8.04(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day.

If any distribution referred to above is declared but not paid or made, the Base Conversion Rate shall be readjusted to be the Base Conversion Rate that would then be in effect if such dividend or distribution had not been declared. For the avoidance of doubt, the adjustment in this clause (c) does not apply to any distributions to the extent that the right to convert Notes has been changed into the right to convert into Reference Property in respect of such distribution in accordance with Section 8.06.

(d) If the Company pays any cash dividend to all or substantially all holders of the Common Stock, the Base Conversion Rate shall be adjusted based on the following formula:

where,


CR₀	=	the Base Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

CR’	=	the new Base Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the ten Trading Days immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C		the amount of such cash dividend applicable to one share of Common Stock.

Such adjustment shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution; provided that if the portion of the cash so distributed applicable to one share of the Common Stock is equal to or greater than SP0 as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Noteholder shall have the right to receive on the date on which the relevant cash dividend or distribution is distributed to holders of Common Stock, for each $1,000 principal amount of Notes upon conversion, the amount of cash such holder would have received had such holder owned a number of shares equal to the Applicable Daily Conversion Rate on the Record Date for such distribution. If such dividend or distribution is not so paid or made, the Base Conversion Rate shall again be adjusted to be the Base Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

For the avoidance of doubt, the adjustment in this clause (d) does not apply to any distributions to the extent that the right to convert Notes has been changed into the right to convert into Reference Property in respect of such distribution in accordance with Section 8.06.

For the avoidance of doubt, for purposes of this Section 8.04(d), in the event of any reclassification of the Common Stock, as a result of which the Notes become convertible into cash and one or more classes of Common Stock, if an adjustment to the Base Conversion Rate is thereafter required pursuant to this Section 8.04(d), references in this Section to one share of Common Stock or Last Reported Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of an amount of cash and shares equal to the number of shares of each class of Common Stock into which the Notes are then convertible plus the cash issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock and the cash and value of any other consideration included in the payment per share of the Common Stock exceeds the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Base Conversion Rate shall be increased based on the following formula:

where,


CR₀	=	the Base Conversion Rate in effect immediately prior to the close of business on the Trading Day next succeeding the date such tender or exchange offer expires;

CR’	=	the new Base Conversion Rate in effect immediately after the close of business on the Trading Day next succeeding the date such tender or exchange offer expires;

AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS₀	=	the number of outstanding shares of Common Stock immediately prior to the date such tender or exchange offer expires;

OS’	=	the number of outstanding shares of Common Stock immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all shares accepted for purchase or exchange pursuant to such tender offer or exchange offer); and

SP’	=	the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Days commencing on, and including, the Trading Day next succeeding the date such tender or exchange offer expires,

such adjustment to become effective immediately after the close of business on the Trading Day immediately following the date such tender or exchange offer expires; provided that, for purposes of determining the Base Conversion Rate, in respect of any Trading Day during a Cash Settlement Averaging Period during the 10 Trading Days immediately following, but excluding, the date that any such tender or exchange offer expires, references in this Section 8.04(e) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and such Trading Date. If the Company or one of its Subsidiaries is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer but is permanently prevented by applicable law from effecting any or all or any portion of such purchases or all such purchases are rescinded, the new Base Conversion Rate shall be readjusted to be the Base Conversion Rate that would then be

in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that had been effected. In no event shall the Base Conversion Rate be decreased pursuant to this Section 8.04(e), except with respect to readjustment described above.

(f) For purposes of this Section 8.04, the term “Record Date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock (or other security) 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) Except as stated herein, the Company shall not adjust the Base Conversion Rate for the issuance of shares of its Common Stock or any securities convertible into or exchangeable for shares of its Common Stock or the right to purchase shares of its Common Stock or such convertible or exchangeable securities.

(h) In addition to those required by clauses Section 8.04(a), (b), (c), (d) and (e) of this Section 8.04, and to the extent permitted by applicable law and subject to the applicable rules of the National Securities Exchange, the Company from time to time may increase the Base Conversion Rate by any amount for a period of at least 20 Business Days. In addition, the Company may also (but is not required to) increase the Base Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event. Whenever the Base Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the holder of each Note at its last address appearing on the Note Register provided for in Section 2.05 a notice of the increase at least 15 calendar days prior to the date the increased Base Conversion Rate takes effect, and such notice shall state the increased Base Conversion Rate and the period during which it will be in effect.

(i) The Base Conversion Rate will not be adjusted:

(i) upon the issuance of any shares of the Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of the Common Stock under any plan;

(ii) upon the issuance of any shares of the Common Stock or restricted stock units or options or rights (including stockholder appreciation rights) to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of the Company’s Subsidiaries;

(iii) upon the issuance of any shares of the Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

(iv) upon the repurchase of any of the Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the nature described in this Section 8.04;

(v) for a change in the par value of the Common Stock;

(vi) for accrued and unpaid interest; or

(vii) for any transactions described in this Section 8.04, if Noteholders participate (as a result of holding the Notes, and at the same time as holders of Common Stock participate) in such transactions as if such Noteholders held a number of shares of Common Stock equal to the Applicable Daily Conversion Rate at the time such adjustment would be required, multiplied by the principal amount (expressed in thousands) of Notes held by such Noteholder, without having to convert their Notes.

(j) All calculations and other determinations under this Article 8 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. Notwithstanding anything in this Section 8.04, the Company will not be required to adjust the Base Conversion Rate unless the adjustment would result in a change of at least 1% of the Base Conversion Rate. However, the Company will carry forward any adjustments that are less than 1% of the Base Conversion Rate and take them into account when determining subsequent adjustments. In addition, the Company will make any carry forward adjustments not otherwise effected (i) upon conversion of the Notes, (ii) in connection with a call for redemption of Notes and (iii) 25 Scheduled Trading Days prior to the Maturity Date of the Notes. No adjustment to the Base Conversion Rate will be made if it results in a Base Conversion Price that is less than the par value (if any) of Common Stock.

(k) At any time the Base Conversion Rate is adjusted as described in this Section 8.04, the Incremental Share Factor and Daily Share Cap will be adjusted in the same proportion.

(l) Whenever the Base Conversion Rate, Incremental Share Factor and Daily Share Cap are 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 Base Conversion Rate, Incremental Share Factor and Daily Share Cap 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 and Conversion Agent shall not be deemed to have knowledge of any adjustment of the Base Conversion Rate, Incremental Share Factor or Daily Share Cap and may assume without inquiry that the last, Base Conversion Rate, Incremental Share Factor and Daily Share Cap 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 Base Conversion Rate, Incremental Share Factor and Daily Share Cap setting forth the adjusted Base Conversion Rate, Incremental Share Factor and Daily Share Cap and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Base Conversion Rate, Incremental Share Factor and Daily Share Cap to the holder of each Note at its last address appearing on the Note Register provided

for in Section 2.05, within 10 calendar days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(m) For purposes of this Section 8.04, 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.

(n) The Board of Directors will make appropriate adjustments, in its good faith determination, to account for any adjustment to the Base Conversion Rate that becomes effective, or any event requiring an adjustment to the Base Conversion Rate where the Ex-Dividend Date of the event occurs, during any consecutive Trading Day period used for the measurement of any adjustment required under this Section 8.04. In addition, if the effective date of any adjustment event described in this 8.04 occurs during a Cash Settlement Averaging Period for any Notes, then the Company will make proportional adjustments to the number of deliverable shares for each Trading Day during the portion of the Cash Settlement Averaging Period preceding the effective date of such adjustment event.

Section 8.05 Shares to Be Fully Paid. 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 conversion of the Notes from time to time as such Notes are presented for conversion.

Section 8.06 Effect of Reclassification, Consolidation, Merger or Sale; Treatment of Reference Property.

(a) Upon the occurrence of (i) any reclassification of the Common Stock (other than a change only in par value, or from par value to no par value, or from no par value to par value, or a change as a result of a subdivision or combination of Common Stock), (ii) any consolidation, merger or combination involving the Company, or (iii) any sale or conveyance to another Person of all or substantially all of the property and assets of the Company, and pursuant to such reclassification, consolidation, merger, combination, sale or conveyance, the Common Stock is converted into or exchanged for stock, other securities, other property or assets (including cash) or any combination thereof (any such event a “Merger Event”), then the Company, or such successor or surviving, purchasing or transferee Person, as the case may be, shall, as a condition precedent to such Merger Event, execute and deliver to the Trustee a supplemental indenture providing that, at the effective time of the Merger Event, the right to receive shares of Common Stock upon conversion of a Note with respect to the portion of the Daily Conversion Value in excess of $50, if any, will be changed into the right to receive the kind and amount of shares of stock, other securities or other property or assets (including cash) or any combination thereof (in the same proportions) that a holder would have been entitled to receive (the “Reference Property”) in such transaction in respect of such Common Stock, and from and after the effective time of such transaction, the Daily Conversion Values and Daily Share Amounts will be determined based on the values and amounts, as applicable, of one unit of Reference Property (a “unit” of Reference Property being the kind and amount thereof (in the same proportions) of Reference Property that a holder of one share of Common Stock would receive in such

transaction) and the Daily Conversion Rate Fractions will relate to such units of Reference Property.

In the event the Company shall execute a supplemental indenture pursuant to this Section 8.06, the Company shall promptly give the Trustee an Officers’ Certificate briefly stating the reasons therefore, the kind or amount of cash, securities or property or asset that will comprise the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Noteholder, at its address appearing on the Note Register provided for in this First Supplemental Indenture, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(b) If the Merger Event causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property into which the Notes will be convertible will be deemed to be the weighted average of the types and amounts of such consideration received by the holders of Common Stock that affirmatively make such an election.

(c) None of the foregoing provisions shall affect the right of a Noteholder to convert its Notes in accordance with the provisions of this Article 8 prior to the effective date of such Merger Event. The provisions of this Section 8.06 shall similarly apply to successive Merger Events.

Section 8.07 Certain Covenants.

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

(b) 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 shall, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

(c) The Company further covenants that if at any time the Common Stock shall be listed on any National Securities Exchange or automated quotation system the Company shall, if permitted and required by the rules of the relevant 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, any Common Stock issuable upon conversion of the Notes.

Section 8.08 Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Noteholder to determine the Applicable Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Base 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, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent 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. 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 8.06 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 8.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01 of the Original Indenture, may accept (without any independent investigation) 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 8.09 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 Base Conversion Rate pursuant to Section 8.04; or

(b) the Company shall authorize the granting to all of the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class or any other rights or warrants that would require an adjustment in the Base Conversion Rate pursuant to Section 8.04; or

(c) of any reclassification of the Common Stock (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 give to the Trustee and to mail to each Noteholder at its address appearing on the Note Register or publicly announce, unless another notice of such event is specified elsewhere in this Supplemental Indenture, at least 15 calendar days prior to the applicable date hereinafter specified, a notice stating (i) 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 (ii) 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 dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.

Section 8.10 Stockholder Rights Plans.

(a) The Company has adopted a stockholder rights plan, pursuant to which certain rights (the “Rights”) are distributed to the holders of Common Stock. The Company’s stockholder rights plan provides that each share of Common Stock issued (including upon conversion of the Notes) at any time prior to the distribution of separate certificates representing such Rights will be entitled to receive such Rights. There shall not be any adjustment to the conversion privilege, the Base Conversion Rate, Incremental Share Factor or Daily Share Cap at any time based on the Company’s stockholder rights plan, any amendment to that plan, or any further stockholder rights plan as contemplated by Section 8.10(b) below that the Company may adopt prior to the distribution of separate certificates representing such Rights. If, however, prior to any conversion, the Rights have separated from the Common Stock, the Base Conversion Rate, Incremental Share Factor and Daily Share Cap shall be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, shares of capital stock, evidences of indebtedness, the Company’s assets, debt securities or rights as described in Section 8.04(c), subject to readjustment in the event of the expiration, termination or redemption of such Rights; provided, however, no person (including a participant in a group within the meaning of Section 13(d)(3) of the Exchange Act) whose actions or ownership caused the separation of the Rights from the Common Stock shall be entitled to such adjustments.

(b) In the event that the Company distributes rights or warrants pursuant to any amendment to the Company’s existing stockholder rights plan, or any further stockholder rights plan to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s capital stock, including Common 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 the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, then such rights or warrants shall be deemed not to have been distributed for purposes of Section 8.04(c) (and no adjustment to the Base Conversion Rate under Section 8.04(c) 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 Base Conversion Rate shall be made under Section 8.04(c) (subject to the proviso in Section 8.10(a)). 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 Base Conversion Rate under Section 8.04(c) 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 Base 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 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 Base Conversion Rate shall be readjusted as if such rights and warrants had not been issued (subject to the proviso in Section 8.10(a)).

ARTICLE 9
Repurchase of Notes at Option of Holders

Section 9.01 Repurchase at Option of Holders.

(a) Notes or portions thereof shall be repurchased by the Company at the option of the holder for cash on each of June 15, 2015, June 15, 2020, June 15, 2025, June 15, 2030 and June 15, 2035 (each, a “Repurchase Date”), at a purchase price (the “Repurchase Price”) equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest thereon to, but excluding, such Repurchase Date. The Company will pay interest due on any such the Repurchase Date to the Noteholder of record on the relevant Interest Record Date, which may or may not be the same Person to whom the Company will pay the Repurchase Price, and the Repurchase Price will not include such interest so paid.

(b) At least 20 Business Days prior to any Repurchase Date, the Company will send a notice (the “Company Notice”) by electronic transmission or by first class mail to the Trustee and to each holder (and to beneficial owners as required by applicable law). The notice shall include the form of Repurchase Notice to be completed by a holder and shall state:

(i) the Repurchase Date;

(ii) the Repurchase Price and the Base Conversion Rate;

(iii) the name and address of the Trustee, (or other Paying Agent appointed by the Company) and the Conversion Agent;

(iv) that Notes as to which a Repurchase Notice has been given may be converted only in accordance with Article 8 and the terms of the Notes if the applicable Repurchase Notice has been withdrawn in accordance with the terms of this Article 9;

(v) that Notes must be surrendered to the Paying Agent to collect payment;

(vi) that the Repurchase Price for any Note as to which a Repurchase Notice has been given and not withdrawn will be paid promptly following the later of the Repurchase Date and the time of surrender of such Note as described in clause (v) above;

(vii) whether or not the Notes are convertible prior to the repurchase and a summary of the procedures for such conversion;

(viii) the procedures the holder must follow to exercise its repurchase rights under this Section 9.01;

(ix) the procedures for withdrawing a Repurchase Notice; and

(x) the CUSIP number of the Notes.

(i) delivery to the Paying Agent by the holder of a written notice of repurchase substantially in the form set forth on the reverse of the Note as Exhibit E thereto (a “Repurchase Notice”) during the period beginning at any time from the open of business on the date that is 20 Business Days prior to the relevant Repurchase Date until the close of business on the Business Day immediately preceding the Repurchase Date stating:

(A) if certificated Notes have been issued, the certificate number of the Notes that the holder will deliver to be purchased;

(B) the portion of the principal amount of the Notes to be purchased, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000; and

(C) that such Notes shall be purchased by the Company as of the Repurchase Date pursuant to the terms and conditions specified in the Notes and in this Supplemental Indenture;

provided, however, that if the Notes are not in certificated form, the Repurchase Notice must comply with appropriate Depositary procedures; and

(ii) book-entry transfer of such Notes (or delivery of such certificated Notes) to the Paying Agent at any time after delivery of the Repurchase Notice (together with all necessary endorsements) at the corporate trust office of the Paying Agent in the United States, such book-entry transfer or delivery being a condition to receipt by the holder of the Repurchase Price therefor; provided, however, that such Repurchase Price shall be so paid pursuant to this Section 9.01 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Repurchase Notice.

(d) No Repurchase Notice with respect to any Notes may be surrendered by a holder thereof if such holder has also tendered a Fundamental Change Repurchase Notice and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 9.02.

(e) The Company may purchase from the holder thereof, pursuant to this Section 9.01, 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 Supplemental Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note.

(f) Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.01 shall be consummated by the payment of the Repurchase Price promptly following

the later of the Business Day following the Repurchase Date and the time of the book-entry transfer or delivery of the Note as described in Section 9.04(a).

(g) Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the Repurchase Notice contemplated by this Section 9.01 shall have the right to withdraw, in whole or in part, such Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 9.03 below.

(h) The Paying Agent shall promptly notify the Company of the receipt by it of any Repurchase Notice or written notice of withdrawal thereof.

(i) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the holders if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Repurchase Date (except in the case of an acceleration resulting from a default by the Company in the payment of the Repurchase Price with respect to such Notes).

If such Fundamental Change Repurchase Date falls after a Interest Record Date and on or prior to the corresponding Interest Payment Date, the Company shall instead pay the principal amount to the Noteholders surrendering the Notes for repurchase pursuant to this Section 9.02, and pay the full amount of accrued and unpaid interest payable on such Interest Payment Date to the holder of record on the close of business on the corresponding Interest Record Date. Repurchases of Notes under this Section 9.02 shall be made on the Fundamental Change Repurchase Date, at the option of the holder thereof, upon:

(i) delivery to the Paying Agent by a holder of a duly completed notice in the form set forth on the reverse of the Note as Exhibit C thereto (the “Fundamental Change Repurchase Notice”) on or prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements) at the corporate trust office of the Paying Agent in the United States, such book-entry transfer or delivery being a condition to receipt by the holder of the Fundamental Change Repurchase Price therefor; provided that such Fundamental Change Repurchase Price shall be so paid pursuant to this Section 9.02 only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice.

The Fundamental Change Repurchase Notice shall state:

(A) if certificated, the certificate numbers of Notes to be delivered for repurchase;

(B) the portion of the principal amount of Notes to be repurchased, which must be $1,000 or an integral multiple thereof; and

(C) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Supplemental Indenture;

provided, however, that if the Notes are not in certificated form, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Any repurchase by the Company contemplated pursuant to the provisions of this Section 9.02 shall be consummated by the payment of the Fundamental Change Repurchase Price promptly following the later of the Business Day following the Fundamental Change Repurchase Date and the time of the book-entry transfer or delivery of the Note as described in Section 9.04(a).

Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 9.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 9.03 below.

The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

(b) Within 15 Business Days after the occurrence of a Fundamental Change, the Company shall give to the Trustee, the Paying Agent and the Conversion Agent and provide or cause to be provided to all holders of record of the Notes a written notice (the “Fundamental Change Company Notice”) of the occurrence of the Effective Date of the Fundamental Change

and of the repurchase right at the option of the holders arising as a result thereof. Simultaneously with the providing of such notice, the Company will also publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time.

Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change;

(ii) the effective date of the Fundamental Change;

(iii) the last date on which a holder may exercise the repurchase right set forth in this Section 9.02;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of the Paying Agent and the Conversion Agent, if applicable;

(vii) the Base Conversion Rate, and if applicable, any adjustments to the Applicable Conversion Rate;

(viii) if applicable, that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a holder may be converted only if the holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of the Indenture;

(ix) that the holder must exercise the repurchase right set forth in this Section 9.02 on or prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date (the “Fundamental Change Expiration Time”);

(x) that the holder shall have the right to withdraw any Notes surrendered prior to the Fundamental Change Expiration Time; and

(xi) the procedures that holders must follow to require the Company to repurchase their Notes.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 9.02.

(c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Xxxxxxxxxxx

(i) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other applicable tender offer rules under the Exchange Act;

(ii) file a Schedule TO or any successor or similar schedule, if required under the Exchange Act; and

(iii) otherwise comply with all applicable U.S. federal and state securities laws in connection with any offer by the Company to purchase the Notes.

Section 9.03 Withdrawal of Repurchase Notice or Fundamental Change Repurchase Notice.

(a) A Repurchase Notice or Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the corporate trust office of the Paying Agent in accordance with the Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, at any time prior to the close of business on the Business Day immediately preceding the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, specifying:

(i) the certificate number, if any, of the Note in respect of which such notice of withdrawal is being submitted, or the appropriate Depositary information if the Note in respect of which such notice of withdrawal is being submitted is represented by a Global Note;

(ii) the principal amount of the Note with respect to which such notice of withdrawal is being submitted; and

(iii) the principal amount, if any, of such Note that remains subject to the original Repurchase Notice or Fundamental Change Repurchase Notice, as the case may be, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000;

provided, however, that if the Notes are not in certificated form, the notice must comply with appropriate procedures of the Depositary.

Section 9.04 Deposit of Repurchase Price or Fundamental Change Repurchase Price. (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04 of the Original Indenture) on or prior to 11:00 a.m., New York City time, on the Business Day following the Repurchase Date or Fundamental Change Repurchase Date, as the case may be, an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Repurchase Price or Fundamental Change Xxxxxxxxxx

Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase (and not withdrawn prior to the Repurchase Date or Fundamental Change Expiration Time, as applicable) will be made on the later of (i) the Business Day following the Repurchase Date or the Fundamental Change Repurchase Date, as the case may be, with respect to such Note (provided the holder has satisfied the conditions in Section 9.01 or Section 9.02, as applicable) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder thereof in the manner required by Section 9.01 or Section 9.02, as applicable, by mailing checks for the amount payable to the holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Repurchase Price or Fundamental Change Repurchase Price, as the case may be.

(b) If by 11:00 a.m., New York City time, on the Business Day following the Repurchase Date or the Fundamental Change Date, as the case may be, the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased, then (i) such Notes will cease to be outstanding and interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent) and (ii) all other rights of the holders of such Notes will terminate (other than the right to receive the Repurchase Price or Fundamental Change Repurchase Price, as the case may be, upon delivery or transfer of the Notes).

(c) Upon surrender of a Note that is to be repurchased in part pursuant to Section 9.01 or Section 9.02, as applicable, the Company shall execute and the Trustee shall authenticate and deliver to the holder a new Note in an authorized denomination equal in principal amount to the unrepurchased portion of the Note surrendered.

Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, except as set forth in Section 4.02 of the Supplemental Indenture, the principal of, premium, if any, and interest on all Notes may be declared, by either the Trustee or Noteholders of not less than 25% in aggregate principal amount of 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.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price, the Repurchase Price and Redemption Price and the principal amount on the Maturity Date, as the case may be, to the holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the holders of the Notes, and in other circumstances, with the consent of the holders of not less than a majority of outstanding principal amount of the Notes, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the holders of a majority of outstanding principal amount of the Notes may on behalf of the holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.
