If any Event of Default with respect to the Company specified in clause (g) or (h) of Section 5.01 occurs, all unpaid principal of, and premium, if any, and accrued and unpaid interest on the Notes then outstanding shall become automatically due and payable, without any declaration or other act on the part of the Trustee or any Holder of Notes.

No such rescission shall affect any subsequent Default or Event of Default or impair any right consequent thereto.

SECTION 5.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy occurring upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 5.04. Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Notes then outstanding may, on behalf of the Holders of all the Notes, waive an existing Default or Event of Default and its consequences, except a Default or Event of Default in the payment of the principal of, and premium, if any, or interest on the Notes (other than the non-payment of principal of, and premium, if any, and interest on the Notes which has become due solely by virtue of an acceleration which has been duly rescinded as provided above), or in respect of a covenant or provision of this Indenture which cannot be modified or amended without the consent of all Holders of Notes. When a Default or Event of Default is waived, it is cured and stops continuing. No waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

SECTION 5.05. Control by Majority. The Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability; provided, however, that the Trustee shall have no duty or obligation (subject to Section 6.02) to ascertain whether or not such actions or forbearances are unduly prejudicial to such

Holders; provided further, however that the Trustee may take any other action the Trustee deems proper that is not inconsistent with such directions.

SECTION 5.06. Limitation on Suits. A Holder of a Note may not pursue any remedy with respect to this Indenture or the Notes unless:

(b) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(c) such Holder or Holders offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 30 days after receipt of the request and the offer and, if requested, the provision of indemnity; and

(e) during such 30-day period the Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

SECTION 5.07. Rights of Holders To Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, or to bring suit for the enforcement of the right to convert the Note shall not be impaired or affected without the consent of the Holder of a Note.

SECTION 5.08. Collection Suit by Trustee. If an Event of Default specified in Section 5.01(a), (b) or (c)(i) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal, premium, if any, and interest and such further amount as shall be sufficient to cover the costs and, to the extent lawful, expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 5.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders of Notes allowed in any judicial proceedings relative to the Company, its creditors or its property. Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Note any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 5.10. Priorities. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Notes or coupons, or both, as the case may be, and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee and any predecessor Trustee under Section 6.07;

SECOND: To the payment of the amounts then due and unpaid upon the Notes for principal (and premium, if any) and interest, in respect of which or for the benefit of which such money has

been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on such Notes for principal (and premium, if any) and interest, respectively; and

THIRD: To the payment of the remainder, if any, to the Company.

SECTION 5.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit, other than the Trustee, of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07 or a suit by Holders of more than 25% in principal amount of the then outstanding Notes.

SECTION 5.12. Restoration of Rights and Remedies. If the Trustee or any Holder of a Note has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Company, the Trustee and the Holders of Notes shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

SECTION 5.13. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities or coupons in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Notes is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 5.14. Waiver of Usury, Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted."

SECTION 5.1. Amendment to Article Ten. Article Ten is amended by adding to the end the following new Sections 10.06 through Section 10.13, in each case with respect to the Notes to read as follows:

"SECTION 10.06. Purchase of Notes at Option of the Holders upon a Designated Event. (a) Following a Designated Event, the Company shall notify the Holders of Notes in writing of such occurrence and shall make an offer (the "Designated Event Offer") to repurchase all Notes then outstanding at a repurchase price in cash (the "Designated Event Payment") equal to 100% of the principal amount thereof, plus (subject to the following sentence) accrued and unpaid interest to, but excluding, the Designated Event Purchase Date (as defined below). If such Designated Event Purchase Date is after a Regular Record Date or a Special Record Date but on or prior to the corresponding Interest Payment Date or a Defaulted Interest payment date, however, then the Company shall pay the interest payable on such date to the Person in whose name the Note is registered at the close of business on the relevant Regular Record Date or Special Record Date.

(b) Notice of a Designated Event shall be mailed by or at the direction of the Company to the Holders of Notes as specified in Section 10.07. During the period specified in such notice, Holders of Notes may elect to tender their Notes in whole or in part in integral multiples of $1,000 in exchange for the Designated Event Payment. Payment shall be made by the Company in respect of Notes properly tendered pursuant to this Section 10.06 on a Business Day specified by the Company (the "Designated Event Purchase Date") which shall be no earlier than 20 Business Days and no later than 30 Business Days after the date of the notice given pursuant to Section 10.07.

SECTION 10.07. Notice of Designated Event; Designated Event Purchase Notice.

(a) Within 30 days after the occurrence of a Designated Event, the Company, or, at the written request and expense of the Company within 30 days after such occurrence, the Trustee, shall give to all Holders notice of the occurrence of the Designated Event and of the purchase right set forth herein arising as a result thereof. The Company shall also deliver a copy of such notice of a purchase right to the Trustee. The notice shall include a form of Designated Event Purchase Notice to be completed by the Holder and shall state:

(1) briefly, the events causing a Designated Event and the date of such Designated Event;

(2) the date by which the Designated Event Purchase Notice pursuant to this Section 10.07 must be given;

(3) the Designated Event Purchase Date;

(4) the Designated Event Payment;

(5) the name and address of the Paying Agent and the Conversion Agent;

(6) that Notes as to which a Designated Event Purchase Notice has been given may be converted pursuant to the Indenture only if the Designated Event Purchase Notice has been withdrawn in accordance with the terms of this Indenture;

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

(8) that the Designated Event Payment for any Note as to which a Designated Event Purchase Notice has been duly given and not withdrawn will be paid promptly following the later

of the Designated Event Purchase Date and the time of surrender of such Note as described in (7) above;

(9) briefly, the procedures the Holder must follow to exercise rights under Section 10.06;

(10) briefly, the conversion rights of the Notes, including the Conversion Rate and any adjustments thereto, including, if such Designated Event constitutes a Change in Control described in clause (b) or (c) in the definition thereof, whether any Additional Shares (as defined in Section 15.01) will be issued by the Company to Holders of Notes who convert their Notes in connection with such Change in Control;

(11) the procedures for withdrawing a Designated Event Purchase Notice;

(12) the CUSIP number of the Notes;

(13) that, unless the Company defaults in making the Designated Event Payment, any Note accepted for purchase pursuant to the Designated Event Offer shall cease to accrue interest on the Designated Event Purchase Date and no further interest shall accrue on or after such date; and

(14) that in the case of a Designated Event Purchase Date that occurs after a Regular Record Date or Special Record Date and on or prior to the corresponding Interest Payment Date or Defaulted Interest payment date, the interest due on such date shall be paid to the Holder of such Note at the close of business on the relevant Regular Record Date or Special Record Date.

(b) A Holder may exercise its rights specified in Section 10.06 hereof upon delivery of a written notice of purchase (a "Designated Event Purchase Notice") to the Paying Agent prior to the Designated Event Purchase Date, stating:

(1) the certificate number, if any, of each Note, if any, which the Holder will deliver to be purchased;

(2) the portion of the principal amount of the Note which the Holder will deliver to be purchased, which portion must be $1,000 or any whole multiple thereof; and

(3) that such Note shall be purchased pursuant to the terms and conditions specified on the reverse side of the Notes and in this Indenture;

provided, however, that if the Notes are not in certificated form, a Holder's Designated Event Purchase Notice must comply with the applicable Depositary procedures.

The delivery of such Note to the Paying Agent prior to the Designated Event Purchase Date (together with all necessary endorsements) at the offices of the Paying Agent shall be a condition to the receipt by the Holder of the Designated Event Payment therefor; provided, however, that such Designated Event Payment shall be so paid only if the Note so delivered to the Paying Agent shall conform in all respects to the description thereof set forth in the related Designated Event Purchase Notice.

The Company shall purchase from the Holder thereof, pursuant to this Section 10.07, a portion of a Note so delivered for purchase if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note.

Any purchase by the Company contemplated pursuant to the provisions of this Section 10.07 shall be consummated by the delivery of the consideration to be received by the Holder promptly following the later of the Designated Event Purchase Date and the time of delivery of the Note to the Paying Agent in accordance with this Section 10.07.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Designated Event Purchase Notice contemplated by this Section 10.07(b) shall have the right to withdraw such Designated Event Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Designated Event Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 10.08.

The Paying Agent shall promptly notify the Company of the receipt by it of any Designated Event Purchase Notice or written withdrawal thereof.

SECTION 10.08. Effect of Designated Event Purchase Notice. Upon receipt by the Paying Agent of the Designated Event Purchase Notice specified in Section 10.07, the Holder of the Note in respect of which such Designated Event Purchase Notice was given shall (unless such Designated Event Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Designated Event Payment with respect to such Note. Such payment shall be paid to such Holder, subject to receipt of consideration for the Notes by the Paying Agent, promptly following the later of (x) the Designated Event Purchase Date with respect to such Note (provided the conditions in Section 10.07, as the case may be, have been satisfied) and (y) the time of delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 10.07, as the case may be. Notes in respect of which a Designated Event Purchase Notice has been given by the Holder thereof may not be converted on or after the date of the delivery of such Designated Event Purchase Notice unless such Designated Event Purchase Notice has first been validly withdrawn as specified in the following two paragraphs.

A Designated Event Purchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent in accordance with the Designated Event Purchase Notice at any time prior to the close of business on the Business Day immediately preceding the Designated Event Purchase Date specifying:

(a) the certificate number, if any, of each Note in respect of which such notice of withdrawal is being submitted;

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

(c) the principal amount, if any, of each such Note which remains subject to the original Designated Event Purchase Notice and which has been or will be delivered for purchase by the Company;

provided, however, that if the Notes are not in certificated form, a Holder's notice of withdrawal must comply with the applicable Depositary procedures.

There shall be no purchase of any Notes pursuant to Section 10.06 if there has occurred (prior to, on or after, as the case may be, the giving by the Holders of such Notes of the required Designated Event Purchase Notice) and is continuing an Event of Default (other than a default in the payment of the Designated Event Payment with respect to such Notes). The Paying Agent will promptly return to the respective Holders thereof any Notes (x) with respect to which a Designated Event Purchase Notice has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default in the payment of the Designated Event Payment with respect to such Notes) in which case, upon such return, the Designated Event Purchase Notice with respect thereto shall be deemed to have been withdrawn.

SECTION 10.09. Deposit of Designated Event Payment. Prior to 11:00 a.m. (New York City time) on the Designated Event Purchase Date, the Company shall deposit with the Trustee or with the Paying Agent an amount of cash (in immediately available funds if deposited on such Business Day) sufficient

to pay the aggregate Designated Event Payment of all the Notes or portions thereof which are to be purchased as of the Designated Event Purchase Date.

If the Trustee or other Paying Agent appointed by the Company holds cash sufficient to pay the aggregate Designated Event Payment of all the Notes or portions thereof that are to be purchased as of the Designated Event Purchase Date, on or after the Designated Event Purchase Date (i) such Notes will cease to be outstanding, (ii) interest on such Notes will cease to accrue and (iii) all other rights of the Holders of such Notes will terminate, whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent, other than the right to receive the Designated Event Payment upon delivery of the Notes.

SECTION 10.10. Notes Purchased in Part. Any Note which is to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder's attorney duly authorized in writing) and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered which is not purchased.

SECTION 10.11. Covenant to Comply with Securities Laws upon Purchase of Notes. In connection with any offer to purchase or purchase of Notes under Section 10.06 hereof (provided that such offer or purchase constitutes an "issuer tender offer" for purposes of Rule 13e-4 (which term, as used herein, includes any successor provision thereto) under the Exchange Act at the time of such offer or purchase), the Company shall (i) comply with Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable, (ii) file the related Schedule TO (or any successor schedule, form or report) or any other schedule required under the Exchange Act, and (iii) otherwise comply with all applicable federal and state securities laws so as to permit the rights and obligations under Section 10.06 to be exercised in the time and in the manner specified in Section 10.06 and 10.07.

SECTION 10.12. Repayment to the Company. The Trustee and the Paying Agent shall return to the Company any cash or other consideration that remains unclaimed as provided in the Notes, together with interest, if any, thereon, held by them for the payment of the Designated Event Payment; provided, however, that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 10.09 exceeds the aggregate Designated Event Payment of the Notes or portions thereof which the Company is obligated to purchase as of the Designated Event Purchase Date then promptly after the Business Day following the Designated Event Purchase Date the Trustee shall return any such excess to the Company together with interest, if any, thereon.

SECTION 10.13. Limitation on Liens. The Company will not, directly or indirectly, incur or suffer to exist any Lien (other than existing Liens) securing Specified Indebtedness of any nature whatsoever on any of its properties or assets, whether owned at the issue date of the Notes or thereafter acquired, without making effective provision for securing the Notes equally and ratably with (or, if the obligation to be secured by the Lien is subordinated in right of payment to the Notes, prior to) the obligations so secured for so long as such obligations are so secured. The Lien, if granted, to secure the Notes may also secure obligations in addition to Specified Indebtedness. Any Lien created to secure the Notes pursuant to this Section 10.13 may provide by its terms that such Lien will be automatically and unconditionally released and discharged upon the full and unconditional release and discharge of the Lien securing the Specified Indebtedness and that the Holders of some or all of such Specified Indebtedness may exclusively control the disposition of property subject to such Lien.

The foregoing restrictions in this Section 10.13 shall not apply to (a) Liens to secure Acquired Debt; provided, however, that (i) such Lien attaches to the acquired property prior to the time of the

acquisition of such property and (ii) such Lien does not extend to or cover any other property; and (b) Liens to secure indebtedness incurred to refinance, in whole or in part, debt secured by any Lien referred to in the foregoing clause (a) or this clause (b) so long as such Lien does not extend to any other property (other than improvements and accessions to the original property) and the principal amount of indebtedness so secured is not increased."

ARTICLE VI
COMPANY REPORTS

SECTION 6.1. Amendments to Article Seven. Section 7.03 of the Indenture is amended in its entirety with respect to the Notes as follows:

"SECTION 7.03. Reports by Company. (a) For so long as the indentures governing any of the Company's outstanding 6.0% Convertible Subordinated Notes due 2009, 11.5% Senior Notes due 2010, 6.0% Convertible Subordinated Notes due 2010, 2.875% Convertible Senior Notes due 2010, 10.0% Convertible Senior Notes due 2011, 5.25% Convertible Senior Notes due 2011, 3.5% Convertible Senior Notes due 2012 or 9% Convertible Senior Discount Notes due 2013 contain a provision with respect to the Company's obligation to file with the Trustee certain information, documents and reports that are substantially identical to the requirements set forth below in this Section 7.03(a), the Company will:

Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers' Certificates)."

ARTICLE VII
CONVERSION OF SECURITIES

SECTION 7.1. Applicability of Conversion Provisions. Pursuant to Section 3.01(24) of the Indenture, the Notes will be convertible in accordance with the provisions of, and pursuant to, Article Fifteen of the Indenture, as amended hereby, and the definitive form of the Notes; provided, however, that, prior to any conversion, any applicable governmental consents have been received by the Company or the Holder.

SECTION 7.2. Amendments to Article Fifteen. Article Fifteen is amended in its entirety with respect to the Notes to read as follows:

"SECTION 15.01. Right To Convert. Subject to and upon compliance with the provisions of this Indenture, each Holder of Notes shall have the right (upon delivery to the Company of the HSR Certificate (a form of which is attached to the Notes)), at his or her option, at any time on or before the close of business on the Stated Maturity date (except that, with respect to any Note or portion thereof subject to a duly completed election for repurchase, such right shall terminate at the close of business on the Business Day immediately preceding the Designated Event Purchase Date (unless the Company defaults in the payment due upon repurchase or such Holder elects to withdraw the submission of such election to repurchase in accordance with Section 10.08)) to convert the principal amount of any Note held by such Holder, or any portion of such principal amount which is $1,000 or an integral multiple thereof, into that number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) obtained by dividing the principal amount of the Note or portion thereof to be converted by the Conversion Price in effect at such time, by surrender of the Note so to be converted in whole or in part in the manner provided in Section 15.02. A Holder of Notes is not entitled to any rights of a holder of Common Stock until such Holder of Notes has converted his or her Notes to Common Stock, and then only to the extent such Notes are deemed to have been converted to Common Stock under this Article Fifteen.

If a Change in Control described in clause (b) or (c) of the definition thereof occurs, then the Conversion Rate per $1,000 principal amount of Notes otherwise in effect in respect of Notes for which a conversion notice is received by the Conversion Agent during the period beginning 10 Trading Days before the anticipated Effective Date (as defined below) of the Change in Control and ending at the close of business on the Trading Day immediately preceding the related Designated Event Purchase Date shall be increased by the amount (the "Additional Shares"), if any, determined by reference to the table below, based on the Effective Date of such Change in Control and the Stock Price of such Change in Control; provided, however, that the Company shall not be required to pay the Additional Shares if a Change in Control described in clause (c) of the definition of Change in Control occurs and at least 90% of the consideration (excluding cash payments for fractional shares) in the transaction or transactions constituting the Change in Control consists of shares of common stock that are, or upon issuance will be, traded on the New York Stock Exchange or the NYSE Alternext or approved for trading on a Nasdaq market and as a result of such transaction or transactions the Notes become convertible solely into such common stock and other consideration payable in such transaction or transactions. The Company will mail a notice to Holders and issue a press release no later than 20 Business Days prior to the anticipated Effective Date of such anticipated Change in Control.

The number of Additional Shares will be determined by reference to the table below and is based on the date on which the Change in Control becomes effective (the "Effective Date") and the price (the "Stock Price") paid per share of Common Stock in the transaction constituting the Change in Control. If holders of the Common Stock receive only cash in the transaction constituting the Change in Control, the Stock Price shall be the cash amount paid per share of the Common Stock. Otherwise, the Stock Price shall be equal to the average of the Closing Sale Price over the five Trading Day period ending on the Trading Day immediately preceding the Effective Date.

The following table sets forth the Additional Shares, if any, issuable upon conversion of each $1,000 principal amount of Notes in connection with such a Change in Control for each Stock Price and Effective Date set forth below.

Additional Shares

$4.00		0.0000		0.0000		0.0000		0.0000		0.0000

If actual Stock Prices on the Effective Date are not set forth on the table above and:

(i) if the actual Stock Price on the Effective Date is between two Stock Prices on the table or the actual Effective Date is between two Effective Dates on the table, the number of Additional Shares will be determined by a straight-line interpolation between the adjustment amounts set forth for such two Stock Prices or such two Effective Dates on the table based on a 360-day year, as applicable;

(ii) if the Stock Price on the Effective Date equals or exceeds $4.00 per share (subject to adjustment as described below), no Additional Shares will be issued upon conversion; and

(iii) if the Stock Price on the Effective Date is less than $0.87 per share (subject to adjustment as described below), no Additional Shares will be issued upon conversion.

The Stock Prices set forth in the first column of the table above will be adjusted as of any date on which the Conversion Rate is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table above will be adjusted in the same manner as the Conversion Rate as set forth in Section 15.05 hereof.

Notwithstanding the foregoing, in no event will the Conversion Rate exceed 1,149.4252 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the manner set forth in Section 15.05 hereof.

SECTION 15.02. Exercise of Conversion Privilege; Issuance of Common Stock on Conversion; No Adjustment for Interest or Dividends. To exercise, in whole or in part, the conversion privilege with respect to any Note, the Holder of such Note shall surrender such Note, duly endorsed, at an office or agency maintained by the Company pursuant to Section 10.02, accompanied by the funds, if any, required by the last paragraph of this Section 15.02, and shall give written notice of conversion in the form provided on the Notes (or such other notice which is acceptable to the Company) to such office

or agency that the Holder of Notes elects to convert such Note or such portion thereof specified in said notice. Such notice shall also state the name or names (with address or addresses) in which the shares of Common Stock which are issuable on such conversion shall be issued, and shall be accompanied by transfer taxes, if required pursuant to Section 15.07. If the Notes are not in certificated form, the Holders may exercise their right of conversion by complying with the applicable Depositary procedures. Each such Note surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the registration of such Note, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the Holder of Notes or his or her duly authorized attorney. The Holder of such Notes will not be required to pay any tax or duty which may be payable in respect of the issue or delivery of Common Stock on conversion, but will be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue or delivery of Common Stock in a name other than the same name as the registration of such Note.

As promptly as practicable after satisfaction of the requirements for conversion set forth above, the Company shall issue the number of full shares of Common Stock (including any full shares as a result of rounding fractional shares up to a full number of shares pursuant to Section 15.03) issuable upon the conversion of such Note or portion thereof in accordance with the provisions of this Article Fifteen and a check or cash (which payment, if any, shall be paid no later than three Business Days after satisfaction of the requirements for conversion set forth above) in respect of any fractional interest in respect of a share of Common Stock, pursuant to Section 15.03. Shares of Common Stock will not be issued or delivered unless all taxes and duties, if any, payable by the Holder have been paid. In case any Note of a denomination of an integral multiple greater than $1,000 is surrendered for partial conversion, and subject to Section 3.03, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of the Note so surrendered, without charge to him or her, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note.

Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date (the "Conversion Date") on which the requirements set forth in this Section 15.02 have been satisfied as to such Note (or portion thereof), and the Person in whose name any shares of Common Stock are issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; provided, however, that any such surrender on any date when the Company's stock transfer books are closed shall constitute the Person in whose name the shares are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Price in effect on the date upon which such Note is surrendered.

Any Note or portion thereof surrendered for conversion during the period from the close of business on the Regular Record Date for any interest payment through the close of business on the last Trading Day immediately preceding such Interest Payment Date shall (unless the Company has specified a Designated Event Purchase Date or an Automatic Conversion Date during such period) be accompanied by payment, in funds acceptable to the Company, of an amount equal to the interest otherwise payable on such Interest Payment Date on the principal amount being converted; provided, however, that such payment may be reduced by the amount of any existing payment default in respect of such Notes. An amount equal to such payment shall be paid by the Company on such Interest Payment Date to the Holder of such Note at the close of business on such Regular Record Date. Except as provided above in this Section 15.02 or in Section 15.12, no adjustment shall be made for interest accrued on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article Fifteen.

SECTION 15.03. Cash Payments in Lieu of Fractional Shares. If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the

Notes (or specified portions thereof to the extent permitted hereby) so surrendered for conversion. In respect of any fractional share of stock that otherwise would be issuable upon the conversion of any Note or Notes, the Company shall make an adjustment therefor in cash based upon the current market price thereof or the Company shall, at its option, round such fraction up to the nearest whole number of shares for issuance upon conversion. For purposes of this Section 15.03, the "current market price" of a share of Common Stock shall be the Closing Sale Price on the last Trading Day immediately preceding the day on which the Notes (or specified portions thereof) are deemed to have been converted.

SECTION 15.04. Conversion Rate. Each $1,000 principal amount of the Notes shall be convertible into the number of shares of Common Stock (the "Conversion Rate") specified in the form of Note attached as Exhibit A hereto, subject to adjustment as provided in this Article Fifteen.

SECTION 15.05. Adjustment of the Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

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

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

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

such increase to become effective immediately after the opening of business on the day following the date fixed for such determination. For the purpose of this paragraph (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this Section 15.05 is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall issue rights or warrants to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the Current Market Price on the date fixed for determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the date fixed for determination of stockholders entitled to receive such rights or warrants by a fraction,

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

(ii) the denominator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for determination of stockholders entitled to receive such rights or warrants plus the number of shares that the aggregate

offering price of the total number of shares so offered would purchase at such Current Market Price.

Such adjustment shall be successively made whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

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

(d) In case the Company shall pay a cash dividend to all holders of its Common Stock or, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of Capital Stock of the Company or evidences of its indebtedness or assets, including cash and securities (any such distribution, a "Distribution"; provided, however, that the term "Distribution" shall not include, and this Section 15.05(d) shall not apply to, (x) any rights or warrants referred to in Section 15.05(b) and (y) any dividend or distribution referred to in Section 15.05(a)), then, in each such case (unless the Company elects to reserve such Distribution for distribution to the Holders upon the conversion of the Notes so that any such Holder converting Notes will receive upon such conversion, in addition to the shares of Common Stock to which such Holder is entitled, the amount and kind of such Distribution which such Holder would have received if such Holder had converted its Notes into Common Stock immediately prior to the Record Date), the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction,

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

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

such adjustment to become effective immediately prior to the opening of business on the day following such Record Date; provided, however, that if the then Fair Market Value (as so

determined) of the portion of the Distribution so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive upon conversion the amount of Distribution such Holder would have received had such Holder converted each Note on the Record Date. If such Distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such Distribution had not been declared. If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 15.05 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 Current Market Price on the applicable Record Date. Notwithstanding the foregoing, if the Distribution distributed by the Company to all holders of its Common Stock consists of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit, the Conversion Rate shall be increased so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to such distribution by a fraction:

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

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

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

Rights or warrants distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company's Capital Stock (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events ("Trigger Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 15.05 (and no adjustment to the Conversion Rate under this Section 15.05 will be required) until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 15.05. If any such right or warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the existing rights or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount

for which an adjustment to the Conversion Rate under this Section 15.05 was made, (1) in the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights and warrants had not been issued.

No adjustment of the Conversion Rate shall be made pursuant to this Section 15.05 in respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent that such rights or warrants are actually distributed, or reserved by the Company for distribution to Holders of Notes upon conversion by such Holders of Notes to Common Stock.

For purposes of this Section 15.05(d) and 15.05(a) and (b), any dividend or distribution to which this Section 15.05(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such shares of Common Stock or rights or warrants (and any Conversion Rate adjustment required by this Section 15.05 with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustment required by Sections 15.05(a) and (b) with respect to such dividend or distribution shall then be made), except

(A) the Record Date of such dividend or distribution shall be substituted as "the date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "the date fixed for the determination of stockholders entitled to receive such rights or warrants" and "the date fixed for such determination" within the meaning of Section 15.05(a) and (b) and

(B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 15.05(a).

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

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

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

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

(f) For purposes of this Section 15.05, the following terms shall have the meaning indicated:

(1) "Current Market Price" shall mean, with respect to any date, the average of the daily Closing Sale Prices per share of Common Stock for the 10 consecutive Trading Days immediately preceding the earlier of such date of determination and the day before the "ex" date with respect to the issuance, distribution, subdivision or combination requiring such computation immediately prior to the date in question. For purpose of this paragraph, the term "ex" date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades, regular way, on the relevant exchange or in the relevant market from which the Closing Sale Price was obtained without the right to receive such issuance or distribution, and (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades, regular way, on such exchange or in such market after the time at which such subdivision or combination becomes effective.

If another issuance, distribution, subdivision or combination to which this Section 15.05 applies occurs during the period applicable for calculating "Current Market Price" pursuant to the definition in the preceding paragraph, "Current Market Price" shall be calculated for such period in a manner determined by the Board of Directors to reflect the impact of such issuance, distribution, subdivision or combination on the Closing Sale Price of the Common Stock during such period.

(2) "Fair Market Value" shall mean the amount which a willing buyer would pay a willing seller in an arm's-length transaction.

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

(g) The Company may make such increases in the Conversion Rate, in addition to those required by Section 15.05(a), (b), (c), (d) or (e) as the Board of Directors considers to be

advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

To the extent permitted by applicable law, the Company from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least twenty (20) days, the increase is irrevocable during the period and the Board of Directors shall have made a determination that such increase would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to Holders of record of the Notes a notice of the increase at least fifteen (15) days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect.

(h) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least one percent (1%) in such rate; provided, however, that any adjustments that by reason of this Article Fifteen are not required to be made shall be carried forward and made (i) as part of any subsequent adjustment or (ii) at the time the Company mails a notice of a Designated Event pursuant to Section 10.06(b) or an Automatic Conversion Notice (as defined below) pursuant to Section 15.12. All calculations under this Article Fifteen shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest. To the extent the Notes become convertible into cash, assets, property or securities (other than capital stock), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on any cash into which the Notes are convertible. The Conversion Rate shall be adjusted only once for a single event or occurrence that would require an adjustment under more than one of Section 15.05(a), (b), (c), (d) or (e).

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

(j) In any case in which this Section 15.05 provides that an adjustment shall become effective immediately after (1) a record date or Record Date for an event, (2) the date fixed for the determination of stockholders entitled to receive a dividend or distribution pursuant to Section 15.05(a), (3) a date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to Section 15.05(b), or (4) the Expiration Time for any tender or exchange offer pursuant to Section 15.05, (each a "Determination Date"), the Company may elect to defer until the occurrence of the applicable Adjustment Event (as hereinafter defined) (x) issuing to the Holder of any Note converted after such Determination Date and before the occurrence of such Adjustment Event, the additional shares of Common Stock or other consideration issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment and

(y) paying to such Holder any amount in cash in lieu of any fractional share pursuant to Section 15.03. For purposes of this Section 15.05(j), the term "Adjustment Event" shall mean:

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

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

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

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

(k) For purposes of this Section 15.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

SECTION 15.06. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur (each, a "Business Combination"): (i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation, merger, share exchange or combination of the Company with another Person or (iii) any sale or conveyance of all or substantially all of the properties and assets of the Company as an entirety or substantially as an entirety, in each case as a result of which holders of Common Stock shall receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that the Holders of the Notes then outstanding will be entitled thereafter to convert such Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) which they would have owned or been entitled to receive upon such Business Combination had such Notes been converted into Common Stock (without giving effect to any adjustment to the Conversion Rate with respect to a Business Combination constituting a Change in Control) immediately prior to such Business Combination, except that such Holders will not receive the Additional Shares if such Holder does not convert during the period set forth in the second paragraph of Section 15.01. In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in such Business Combination, the Company shall make adequate provision whereby the Notes shall be convertible from and after the effective date of such Business Combination into the form of consideration received in such Business Combination by Holders of the greatest number of shares of Common Stock who made a given election with respect to the form of consideration. The Company may not become a party to any Business Combination unless its terms are consistent with this Section 15.06. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article Fifteen. If, in the case of any such Business Combination, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a Person other than the successor or purchasing Person, as the case may be, in such Business Combination, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the purchase rights set forth in Section 10.06 hereof. Notwithstanding anything contained in this Section, and for the avoidance of doubt, this Section shall

not affect the right of a Holder to convert its Notes into shares of Common Stock prior to the effective date of the Business Combination.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder of Notes within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

The above provisions of this Section 15.06 shall similarly apply to successive reclassifications, changes, consolidations, mergers, share exchanges, combinations, sales and conveyances.

If this Section 15.06 applies to any event or occurrence, Section 15.05 shall not apply.

SECTION 15.07. Taxes on Shares Issued. The issue of shares on conversions of Notes shall be made without charge to the converting Holder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Note converted, and the Company shall not be required to issue or deliver any such shares unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

SECTION 15.08. Reservation of Shares; Shares to Be Fully Paid; Listing of Common Stock. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes from time to time as such Notes are presented for conversion. Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company shall take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate.

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

The Company further covenants that as long as the Common Stock is approved for trading on the Nasdaq Global Select Market, or its successor, the Company shall cause all Common Stock issuable upon conversion of the Notes to be eligible for such quotation in accordance with, and at the times required under, the requirements of such market, and if at any time the Common Stock becomes listed on the New York Stock Exchange or any other national securities exchange, the Company shall cause all Common Stock issuable upon conversion of the Notes to be so listed and remain listed.

SECTION 15.09. Responsibility of Trustee. The Trustee and any Conversion Agent shall have no duty, responsibility or liability to any Holder to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent 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. Neither the Trustee nor any Conversion Agent shall be accountable with respect to the registration under securities laws, listing, validity or value (or the kind or amount) of any shares of Common Stock, or of any other securities or property, which may at any time be issued or delivered upon the conversion of any Note, and neither the Trustee nor any Conversion Agent makes any representation with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to make any cash payment or to issue, transfer or deliver any shares of stock or stock certificates or other securities or property upon the surrender of any Note for the purpose of conversion; and the Trustee and any Conversion Agent shall not be responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article Fifteen.

SECTION 15.10. Notice to Holders Prior to Certain Actions. If:

(a) the Company declares a dividend (or any other distribution) on its Common Stock (other than in cash out of retained earnings);

(b) the Company authorizes the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class of Common Stock or any other rights or warrants (other than rights or warrants referred to in the second paragraph of Section 15.05(d));

(c) there is any reclassification of the Common Stock (other than a subdivision or combination of 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, merger or share exchange to which the Company is a party, or of the sale or transfer of all or substantially all of the assets of the Company; or

(d) there is any voluntary or involuntary dissolution, liquidation or winding-up of the Company;

then the Company shall cause to be filed with the Trustee and at the office or agency maintained for the purpose of conversion of the Notes pursuant to Section 10.02, and shall caused to be mailed to each Holder of Notes, at their last addresses as they shall appear on the Security Register of the Company as promptly as possible but in any event at least 10 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend or distribution of 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 or distribution are to be determined or (y) the date on which such reclassification, consolidation, merger, share exchange, 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, share exchange, 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, share exchange, sale, transfer, dissolution, liquidation or winding-up. The Company shall also disseminate a press release through Dow ▇▇▇▇▇ & Company Inc., Bloomberg Business News, PR Newswire or another comparable news service containing this information.

SECTION 15.11. Rights Issued in Respect of Common Stock Issued Upon Conversion. If the Company has a stockholder rights plan in effect on any Conversion Date, the Company shall issue, in addition to the Common Stock, the rights under the rights plan unless the rights have separated from the Common Stock at the time of conversion, in which case the Conversion Rate will be adjusted as if the Company had distributed to all holders of the Common Stock, shares of the Capital Stock, evidences of indebtedness or assets as set forth in Section 15.05, subject to readjustment in the event of the expiration, termination or redemption of such rights.

SECTION 15.12. Automatic Conversion.

(a) If at any time following the date of original issuance of the Notes and on or prior to the Stated Maturity, the Closing Sale Price exceeds 222.2% of the Conversion Price then in effect for at least twenty (20) Trading Days in any thirty (30) consecutive Trading Day period (an "Automatic Conversion Event"), the Notes shall automatically convert into shares of Common Stock at the then applicable Conversion Rate on the Automatic Conversion Date (as defined below) specified in the Automatic Conversion Notice (as defined below) (the "Automatic Conversion").

Without the consent of any Holder, the Indenture or the Notes may be amended to: (a) cure any ambiguity or correct or supplement any defective or inconsistent provision contained in the Indenture, or make any other changes in the provisions of the Indenture which the Company and the Trustee may deem necessary or desirable provided such amendment does not materially and adversely affect the legal rights under the Indenture of the Holders of Notes; (b) provide for uncertificated Notes in addition to or in place of certificated Notes; (c) evidence the succession of another Person to the Company and provide for the assumption by such successor of the covenants and obligations of the Company thereunder and in the Notes as permitted by Section 8.01 of the Indenture; (d) provide for conversion rights or repurchase rights of Holders of Notes in the event of consolidation, merger, share exchange or sale of all or substantially all of the assets of the Company as required to comply with Sections 8.01 or 15.06 of the Indenture; (e) reduce the Conversion Price; (f) add guarantees with respect to the Notes; (g) evidence and provide for the acceptance of the appointment under the Indenture of a successor Trustee or to provide for or facilitate the administration of the trusts by more than one Trustee; (h) make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under the Indenture of any such Holder; (i) comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the TIA; (j) secure the Notes; or (k) permit or facilitate the defeasance and discharge of Notes.

Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require an indemnity reasonably satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except, among other things, a default in payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interests. The Company must furnish annual compliance certificates to the Trustee.
11.: TRUSTEE DEALINGS WITH THE COMPANY. The Trustee or any of its Affiliates, in their individual or any other capacities, may make or continue loans to or guaranteed by, accept deposits from and perform services for the Company or its Affiliates and may otherwise deal with the Company or its Affiliates as if it were not Trustee.
12.: NO RECOURSE AGAINST OTHERS. No director, officer, employee, shareholder or Affiliate, as such, of the Company shall have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their

Subject to the aforesaid requirement for a payment in the event of conversion after the close of business on a Regular Record Date immediately preceding an Interest Payment Date, no adjustment shall be made on conversion for interest accrued hereon or for dividends on Common Stock delivered on conversion. The right to convert this Note is subject to the provisions of the Indenture relating to conversion rights in the case of certain consolidations, mergers, share exchanges or sales or transfers of substantially all the Company's assets.

The Notes shall automatically convert (the "Automatic Conversion") on the Automatic Conversion Date (as defined below) into shares of Common Stock at the then applicable Conversion Rate (plus accrued and unpaid interest on the Notes to, but excluding, the Automatic Conversion Date), if at any time following the date of original issuance of the Notes and on or prior to the State Maturity the Closing Sale Price (as defined in the Indenture) per share of the Common Stock exceeds 222.2% of the Conversion Price then in effect for at least twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days (an "Automatic Conversion Event"). Following the occurrence of an Automatic Conversion Event, at the request and expense of the Company, the Trustee shall mail or cause to be mailed to each Holder notice (the "Automatic Conversion Notice") of the Automatic Conversion Event, which notice shall

specify the date designated by the Company for the Automatic Conversion to become effective (such effective date, the "Automatic Conversion Date"). The Automatic Conversion Date shall be no less than three (3) Business Days after the date of the Automatic Conversion Notice.

The Conversion Rate on any Notes converted in connection with certain specified Changes in Control as designated in the Indenture may be increased by an amount, if any, determined in accordance with Article Fifteen of the Indenture.

The Company shall, in respect of fractional shares representing fractions of shares of Common Stock upon any such conversion, make an adjustment in cash based upon the current market price of the Common Stock on the last Trading Day prior to the date of conversion or round such fraction up to the nearest whole number of shares.

The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to: Level 3 Communications, Inc., ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: Vice President, Investor Relations, or by telephone at (▇▇▇) ▇▇▇-▇▇▇▇.
