The Securities shall be executed on behalf of the Company by its Chairman of the Board, one of its Vice Chairman, its President, one of its Senior Vice Presidents or one of its Vice Presidents, under its corporate seal reproduced thereon and attested by its Secretary or one of its Assistant Secretaries.

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of authentication of such Securities.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

The Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount of up to $120,000,000 upon a Company Order without any further action by the Company.

The Company may have one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term Paying Agent includes any additional paying agent.

At any time during the continuance of any such default, the Paying Agent shall, upon the written request of the Trustee, forthwith pay to the Trustee all money and securities so held in trust. If the Company, a Subsidiary or an Affiliate of either of them acts as Paying Agent, it shall segregate the money and securities held by it as Paying Agent and hold it as a separate trust fund.

Upon doing so, the Paying Agent shall have no further liability for the money or securities.

(d) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof whether pursuant to this Article Two or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

(e) The Depositary or its nominee, as registered own of a Global Security, shall be the Holder of such Global Security for all purposes under the Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the applicable procedures. Accordingly, any such owner’s beneficial interest in a Global Security will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its agent members and such owners of beneficial interests in a Global Security will not be considered the owners or holders thereof.

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 Securities in global form. Initially, the Global Security 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 Cede & Co.

If at any time the Depositary for the Global Security notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security, the Company may appoint a successor Depositary with respect to such Security. If a successor Depositary for the Global Security is not appointed by the Company within 90 days after the Company receives such notice, the Company will execute, and the Trustee, upon receipt of a Company Order for authentication and delivery of Securities, will authenticate and deliver, Securities in definitive

form, in an aggregate principal amount equal to the principal amount of the Global Security, in exchange for such Security in the global form.

Section 2.07. Replacement Securities. If (i) any mutilated Security is surrendered to the Trustee, or (ii) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be redeemed by the Company pursuant to Article 3 hereof, the Company in its discretion may, instead of issuing a new Security, pay or redeem such Security, as the case may be.

Upon the issuance of any new Securities under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 2.08. Outstanding Securities; Determinations of Holders’ Action. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate thereof holds the Security; provided, however, that in determining whether the Holders of the requisite principal amount of Securities have given or concurred in any request, demand, authorization, direction, notice, consent or waiver hereunder, Securities owned by the Company or any other obligor upon the Securities or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be

outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only Securities which the Trustee knows to be so owned shall be so disregarded. Subject to the foregoing, only Securities outstanding at the time of such determination shall be considered in any such determination (including, without limitation, determinations pursuant to Articles 6 and 9).

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

If the Paying Agent holds, in accordance with this Indenture, on a Redemption Date, on a Fundamental Change Repurchase Date or on Stated Maturity, money or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then on and after that date such Securities shall cease to be outstanding and interest on such Securities shall cease to accrue; provided, that if such Securities are to be redeemed, notice of such redemption has been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee has been made.

If a Security is converted in accordance with Article 10, then from and after such conversion such Security shall cease to be outstanding and interest shall cease to accrue on such Security.

Section 2.09. Temporary Securities. Pending the preparation of definitive Securities, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as conclusively evidenced by their execution of such Securities.

If temporary Securities are issued, the Company will cause definitive Securities to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at the office or agency of the Company designated for such purpose pursuant to Section 2.03, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations. Until so exchanged the temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities.

Section 2.10. Cancellation. All Securities surrendered for payment, conversion, redemption or registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. The Company may not issue new Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be destroyed by the Trustee and evidence of their destruction delivered to the Company unless the Company directs by Company Order that the Trustee deliver canceled Securities to the Company.

Section 2.11. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal amount, premium, if any, interest, Redemption Price and Fundamental Change Redemption Price in respect thereof, for the purpose of conversion and for all other purposes whatsoever, whether or not such Security be overdue, and none of the Company, the Trustee or any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12. Payment of Interest; Interest Rights Preserved. Interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security which is payable, but is not punctually paid or dully provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed

payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at his address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following Clause (b).

(b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or market on which the Securities may be listed, and upon such notice as may be required by such exchange or market, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

In the case of any Security which is converted after any Regular Record Date on or prior to the close of business on the next succeeding Interest Payment Date (other than any Security whose Maturity is prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date shall be payable on such Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or dully provided for) shall be paid to the Person whose name that Security (or one or more Predecessor Securities) is registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Security which is converted, interest whose Stated Maturity is after the date of conversion of such Security shall not be payable.

Section 2.13. Computation of Interest. Interest on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 2.14. Preservation of Information; Communications to Holders.

(a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders contained in the most recent list furnished to the Trustee as provided in Section 2.05 and the names and addresses of Holders received by the Trustee in its capacity as Security Registrar. The Trustee may destroy any list furnished to it as provided in Section 2.05 upon receipt of a new list so furnished.

(b) The rights of Holders to communicate with other Holders with respect to their rights under this Indenture or under the Securities, and the corresponding right and duties of the Trustee, shall be as provided in the TIA.

(c) Every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee nor any agent of either of them shall be held accountable by reason of the disclosure of information as to names and addresses of the Holders made pursuant to the TIA.

ARTICLE 3
REDEMPTION

Section 3.01. Right to Redeem; Notices to Trustee. The Company, at its option, may redeem the Securities in accordance with the provisions of paragraph 5 of the Securities. If the Company elects to redeem Securities pursuant to paragraph 5 of the Securities, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Securities to be redeemed, the Redemption Price, and the amount of accrued interest to, but excluding, the Redemption Date.

The Company shall give the notice to the Trustee provided for in this Section 3.01 (i) in the case of any redemption of fewer than all of the Securities, at least 45 days before the Redemption Date and (ii) in the case of a redemption of all of the Securities, no later than the Company is required to give notice to the Holders pursuant to Section 3.03, in each case unless a shorter notice shall be satisfactory to the Trustee.

Section 3.02. Selection of Securities to be Redeemed. If less than all the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed pro rata or by lot or by a method the Trustee considers fair and appropriate (as long as such method is not prohibited by the rules of any stock

exchange or automated quotation system on which the Securities are then listed). The Trustee shall make the selection at least 10 days, but not more than 60 days, before the Redemption Date from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal amount of Securities that have denominations larger than $1,000. Securities and portions of Securities selected by the Trustee shall be in principal amounts of $1,000 or a multiple of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed.

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

Section 3.03. Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail a notice of redemption by first-class mail, postage prepaid, to each Holder of Securities to be redeemed.

The notice shall identify the Securities to be redeemed and shall state:

(a) the Redemption Date;

(b) the Redemption Price, together with the amount of accrued interest to, but excluding, the Redemption Date;

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

(e) that Securities called for redemption may be converted at any time before the close of business on the last Trading Day prior to the Redemption Date;

(f) that Holders who want to convert Securities must satisfy the requirements set forth in paragraph 7 of the Securities;

(g) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and accrued interest to, but excluding, the Redemption Date;

(h) if fewer than all the outstanding Securities are to be redeemed, the certificate number and principal amounts of the particular Securities to be redeemed; and

(i) that interest on Securities called for redemption will cease to accrue on and after the Redemption Date.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense.

Section 3.04. Effect of Notice of Redemption. Once notice of redemption is given, Securities called for redemption become due and payable on the Redemption Date and at the Redemption Price, together with accrued interest to, but excluding, the Redemption Date, stated in the notice except for Securities which are converted in accordance with the terms of this Indenture.

Upon the later of the Redemption Date or the date such Securities are surrendered to the Paying Agent, such Securities shall be paid at the Redemption Price, together with accrued interest to, but excluding, the Redemption Date, stated in the notice.

Section 3.05. Deposit of Redemption Price. Prior to or on the Redemption Date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary or an Affiliate of either of them is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the Redemption Price and accrued interest to, but excluding, the Redemption Date of all Securities to be redeemed on that date other than Securities or portions of Securities called for redemption which prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted; provided that if such payment is made on the Redemption Date it must be received by the Trustee or Paying Agent, as the case may be, by 10:00 a.m. New York City time, on such Redemption Date. The Paying Agent shall as promptly as practicable return to the Company any money, with interest, if any, thereon (subject to the provisions of Section 7.01(f)), not required for that purpose because of conversion of Securities. If such money is then held by the Company in trust and is not required for such purpose it shall be discharged from such trust.

Section 3.06. Securities Redeemed in Part. Upon surrender of a Security that is redeemed in part, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Security in an authorized denomination equal in principal amount to the unredeemed portion of the Security surrendered.

Section 3.07. Conversion Arrangement on Call for Redemption. In connection with any redemption of Securities, the Company may arrange for the

purchase and conversion of any Securities called for redemption by an agreement with one or more investment bankers or other purchasers to purchase such Securities by paying to the Paying Agent in trust for the Securityholders, on or before the close of business on the Redemption Date, an amount that, together with any amounts deposited with the Paying Agent by the Company for the redemption of the Securities, is not less than the Redemption Price, together with interest, if any, accrued to the Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article 3, the obligation of the Company to pay the Redemption Price of such Securities, including all accrued interest, shall be deemed to be satisfied and discharged to the extent such amount is so paid by such purchasers. If such an agreement is entered into, any Securities not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, acquired by such purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 10) surrendered by such purchasers for conversion, all immediately prior to the close of business on the Redemption Date, subject to payment of the above amount as aforesaid.

The Paying Agent shall hold and pay to the Holders whose Securities are selected for redemption any such amount paid to it in the same manner as it would moneys deposited with it by the Company for the redemption of Securities. Without the Paying Agent’s prior written consent, no arrangement between the Company and such purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Paying Agent as set forth in this Indenture, and the Company agrees to indemnify the Paying Agent from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such purchasers, including the costs and expenses incurred by the Paying Agent in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture.

Section 3.08. Redemption at Option of the Holder upon a Fundamental Change. (a) If a Fundamental Change shall occur at any time prior to July 1, 2009, each Holder of Securities shall have the right, at such Holder’s option, to require the Company to redeem such Holder’s Securities on the date (the “Fundamental Change Repurchase Date”) (or if such date is not a Business Day, the next succeeding Business Day) that is 45 days after the date of the Company’s notice of such Fundamental Change. The Securities will be redeemable in part in multiples of $1,000 of principal amount. Such repayment shall be made at 100% of the principal amount (the “Fundamental Change Redemption Price”) thereof. In each case, the Company shall also pay to such Holders accrued interest to, but excluding, the Fundamental Change Repurchase Date on the redeemed Securities; provided that if such Fundamental Change

Repurchase Date is an Interest Payment Date, then the interest payable on such date shall be paid to the Holder of the Security on the next preceding the Regular Record Date.

(b) On or before the tenth day after the occurrence of a Fundamental Change, the Company, or, at its written request (which must be received by the Trustee at least five Business Days prior to the date the Trustee is requested to give notice as described below), the Trustee in the name of and at the expense of the Company, shall mail or cause to be mailed to all Holders of record on the date of the Fundamental Change a notice (the “Company Notice”) of the occurrence of such Fundamental Change and of the redemption right at the option of the Holders arising as a result thereof. Such notice shall be mailed in the manner and with the effect set forth in Section 3.03. The Company shall also deliver a copy of the Company Notice to the Trustee at such time as it is mailed to the Holders.

Each Company Notice shall specify the circumstances constituting the Fundamental Change, the Fundamental Change Repurchase Date, the Fundamental Change Redemption Price at which the Company shall be obligated to redeem the Securities, the amount of interest accrued on each Security to, but excluding, the Fundamental Change Repurchase Date, the latest time by which the Holder must exercise the redemption right (the “Fundamental Change Expiration Time”), that the Holder shall have the right to withdraw any Notes prior to the Fundamental Change Expiration Time, a description of the procedure which a Holder must follow to exercise such redemption right and to withdraw any surrendered Notes and the place or places where the Holder is to surrender such Holder’s Securities.

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ redemption rights or affect the validity of the proceedings for the repurchase of the Securities pursuant to this Section 3.08.

(c) For a Security to be so redeemed at the option of the Holder, the Paying Agent must receive such Security with the form entitled “Option to Elect Redemption Upon a Fundamental Change” on the reverse thereof duly completed (a “Fundamental Change Redemption Notice”), together with such Security duly endorsed for transfer, on or before the 30th day after the date of such Company Notice (or if such 30th day is not a Business Day, the immediately preceding Business Day). All questions as to the validity, eligibility (including time of receipt) and acceptance of any Security for redemption shall be determined by the Company, whose determination shall be final and binding.

(d) Upon receipt by the Company of the Fundamental Change Redemption Notice specified in Section 3.08(c), the Holder of the Security in respect of which such Fundamental Change Redemption Notice was given shall (unless such Fundamental Change Redemption Notice is withdrawn as specified

in the following two paragraphs) thereafter be entitled to receive solely the Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, with respect to such Security. Such Fundamental Change Redemption Price together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, shall be paid to such Holder promptly following the Fundamental Change Repurchase Date. Securities in respect of which a Fundamental Change Redemption Notice has been given by the Holder thereof may not be converted into shares of Common Stock on or after the date of the delivery of such Fundamental Change Redemption Notice, unless such Fundamental Change Redemption Notice has first been validly withdrawn as specified in the following two paragraphs.

A Fundamental Change Redemption Notice may be withdrawn by the Holder by means of a written notice of withdrawal delivered to the office of the Paying Agent at any time prior to the close of business on the Fundamental Change Repurchase Date to which it relates specifying:

(i) the certificate number of the Security in respect of which such notice of withdrawal is being submitted,

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

(iii) the principal amount, if any, of such Security which remains subject to the original Fundamental Change Redemption Notice and which has been or will be delivered for purchase by the Company.

There shall be no redemption pursuant to Section 3.08 if there has occurred prior to, on or after, as the case may be, the giving, by the Holders of such Securities, of the required Fundamental Change Redemption Notice and is continuing an Event of Default (other than a default in the payment of the Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, with respect to such Securities).

(e) On or before the Fundamental Change Repurchase Date the Company shall deposit with the Trustee or with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of either of them is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money and/or securities, if permitted hereunder, sufficient to pay the aggregate Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, of all the Securities or portions thereof which are to be redeemed as of such Fundamental Change Repurchase Date; provided that if such payment is made on the Fundamental Change Repurchase Date it must be received by the Trustee or Paying Agent, as

the case may be, by 10:00 a.m. New York City time, on such Fundamental Change Repurchase Date.

(f) Any Security that is to be redeemed upon a Fundamental Change 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, upon the Company’s written direction to the Trustee, the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, 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 Security so surrendered which is not redeemed.

(g) In connection with any offer to redeem Securities under Section 3.08 hereof the Company shall comply with all Federal and state securities laws so as to permit the rights and obligations under Section 3.08 to be exercised in the time and in the manner specified in Section 3.08.

(h) The Trustee and the Paying Agent shall return to the Company any cash that remains unclaimed as provided in paragraph 11 of the Securities, together with interest or dividends, if any (subject to the provisions of Section 7.01(f)), thereon, held by them for the payment of a Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date; provided, however that to the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.08 exceeds the aggregate Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, of the Securities or portions thereof which the Company is obligated to purchase as of the Fundamental Change Repurchase Date then promptly after the Business Day following the Fundamental Change Repurchase Date the Trustee and the Paying Agent shall return any such excess to the Company together with interest or dividends, if any, thereon.

The Company shall pay interest at the rate set forth in paragraph 1 of the Securities and it shall pay interest on overdue interest at the same rate compounded semiannually (to the extent that the payment of such interest shall be legally enforceable), which interest on overdue interest shall accrue from the date such amounts became overdue.

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 address of the Trustee set forth in Section 11.02.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, The City of New York, for such purposes.

Section 4.06. Restriction on Additional Indebtedness. The Company shall not, nor shall it permit any Subsidiary to, directly or indirectly (including by means of a merger or an acquisition involving a company with outstanding indebtedness), create, incur, assume, guaranty or otherwise become directly or indirectly liable for (“Incur”) any additional indebtedness for borrowed money (other than additional indebtedness that is (i) in an aggregate principal amount no greater than $35,000,000, (ii) is subordinate in right of payment to all amounts payable under the Securities and New Convertible Notes, (iii) does not have a final Stated Maturity prior to the Stated Maturity of the Securities and the New Convertible Notes, and (iv) has an Average Life at least equal to the remaining Average Life of the Securities and the New Convertible Notes) or issue any Disqualified Stock, except that the Company may, and may permit any Subsidiary to Incur additional indebtedness

(a) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance, transfer or lease the properties and assets of the Company substantially as an entirety (i) shall be a corporation, partnership or trust organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (ii) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all of the obligations of the Company under the Securities and this Indenture;

ARTICLE 6
DEFAULTS AND REMEDIES

Section 6.01. Events of Default. “Event of Default” occurs if:

(a) the Company defaults in the payment of the principal amount of, premium, if any, Redemption Price or Fundamental Change Redemption Price on any Security when the same becomes due and payable at its Stated Maturity, upon redemption, upon declaration or otherwise;

(b) the Company defaults in the payment of any installment of interest upon any of the Securities as and when the same shall become due and payable, and continuance of such default for 30 days;

(c) the Company fails to comply with any of its agreements in the Securities or this Indenture (other than those referred to in clause (1) or (2) above) and such failure continues for 60 days after receipt by the Company of a Notice of Default;

(d) a decree or order by a court having jurisdiction in the premises shall have been entered adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization of the Company under any Bankruptcy Law, and such decree or order shall have continued undischarged and unstayed for a period of 60 consecutive days; or a decree or order of a court having jurisdiction in the premises of the appointment of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of the Company or of its property, or for the winding-up or liquidation of its affairs, shall have been entered, and such decree or order shall have remained in force undischarged and unstayed of a period of 60 consecutive days; or

(e) the Company shall institute proceedings to be adjudicated a voluntary bankrupt, or shall consent to the filing of a bankruptcy proceeding against it, or shall file a petition or answer or consent seeking reorganization under any Bankruptcy Law, or shall consent to the filing of any such petition, or shall consent to the appointment of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of it or of its property or shall make an assignment for the benefit of creditors, or shall admit in writing its inability to pay its debts generally as they become due.

(f) an event of default under the Secured Credit Facility, the Old Notes Indenture or the New Convertible Indenture shall have occurred which results in the principal amount and accrued interest on that debt becoming immediately due and payable.

“Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state law for the relief of debtors.

A Default under (c) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding notify the Company and the Trustee, of the Default and the Company does not cure such Default (and such Default is not waived) within the time specified in clause (3) above after actual receipt of such notice (a “Notice of Default”). Any such notice must specify the Default, demand that it be remedied and state that such notice is a Notice of Default.

Section 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.01(d) or (e)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding by notice to the Company and the Trustee, may declare the principal amount and premium, if any, on all the Securities and the interest accrued thereon to be immediately due and payable. Upon such a declaration, such principal amount, premium, if any, and interest accrued thereon shall be due and payable immediately. If an Event of Default specified in Section 6.01(d) or (e) occurs and is continuing, the principal amount and premium, if any, on all the Securities and the interest accrued thereon shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder) may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of the principal amount, premium, if any, and interest accrued thereon that has become due solely as a result of acceleration and if all amounts due to the Trustee under Section 7.07 have been paid. No such

rescission shall affect any subsequent Default or impair any right consequent thereto.

Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of the principal amount and premium, if any, on the Securities and interest accrued thereon or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if the Trustee does not possess any of the Securities or does not produce any of the Securities in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of, or acquiescence in, the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 6.04. Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Securityholder), may waive an existing Default and its consequences except (1) an Event of Default described in Section 6.01(a) or 6.01(b), (2) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected, or (3) a Default that constitutes a failure to convert any Security in accordance with the terms of Article 10. When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

Section 6.05. Control by Majority. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it.

Section 6.06. Limitation on Suits. A Securityholder may not pursue any remedy with respect to this Indenture or the Securities unless:

(a) the Holder gives to the Trustee written notice stating that an Event of Default is continuing;

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

(c) such Holder or Holders offer to the Trustee reasonable security or indemnity against any loss, liability or expense satisfactory to the Trustee;

(d) the Trustee does not comply with the request within 60 days after receipt of the notice, the request and the offer of security or indemnity; and

(e) the Holders of a majority in aggregate principal amount of the Securities at the time outstanding do not give the Trustee a direction inconsistent with the request during such 60-day period.

A Securityholder may not use this Indenture to prejudice the rights of any other Securityholder or to obtain a preference or priority over any other Securityholder.

Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the principal amount, premium, if any, accrued interest, Redemption Price or Fundamental Change Redemption Price in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities or any Redemption Date or Fundamental Change Repurchase Date, as the case may be, and to convert the Securities in accordance with Article 10, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall, not be impaired or affected adversely without the consent of each such Holder.

Section 6.08. Collection Suit by Trustee. If an Event of Default described in Section 6.01(a) or Section 6.01(b) 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 owing with respect to the Securities and the amounts provided for in Section 7.07.

Section 6.09. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal amount, premium, if any, accrued interest, Redemption Price or Fundamental Change Redemption Price in respect of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company

for the payment of any such amount) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(a) to file and prove a claim for the whole amount of the principal amount, premium, if any, accrued interest, Redemption Price or Fundamental Change Redemption Price and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claims of any Holder in any such proceeding.

Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 7.07;

Second: to Securityholders for amounts due and unpaid on the Securities for the principal amount, premium, if any, accrued interest, Redemption Price or Fundamental Change Redemption Price, as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Securities; and

Third: the balance, if any, to the Company.

The Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. At least 15 days before such record date, the Company shall mail to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid.

Section 6.11. 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 Trustee, a court in its discretion may require the filing by any party litigant (other than the Trustee) in the suit 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at the time outstanding.

Section 6.12. Waiver of Stay, Extension or Usury 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 stay or extension law or any usury or other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal amount, premium, if any, accrued interest, Redemption Price or Fundamental Change Redemption Price in respect of Securities as contemplated herein, or 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 laws 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.

ARTICLE 7
TRUSTEE

Section 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(b) Except during the continuance of an Event of Default:

(i) the Trustee need perform only those duties that are specifically set forth in this Indenture and no others; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to

determine whether or not they conform to the requirements of this Indenture.

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(i) this paragraph (c) does not limit the effect of paragraph (b) of this Section 7.01;

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 7.01.

(e) The Trustee may refuse to perform any duty or exercise any right or power or extend or risk its own funds or otherwise incur any financial liability unless it receives indemnity satisfactory to it against any loss, liability or expense.

(f) Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law.

Section 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require a Company Order, an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Company Order, Officers’ Certificate or Opinion of Counsel.

(c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(d) Subject to the provisions of Section 7.01(c), the Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers.

Section 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may

otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, Conversion Agent or co-registrar may do the same with the like rights. However, the Trustee must comply with Section 7.10.

Section 7.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, it shall not be responsible for any statement in the Prospectus for the Securities or in the Indenture of the Securities (other than its certificate of authentication), the acts of an prior Trustee hereunder, or the determination as to which beneficial owners are entitled to receive any notices hereunder.

Section 7.05. Notice of Defaults. If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall give to each Securityholder notice of the Default within 90 days after it occurs. Except in the case of a Default described in Section 6.01(a) or Section 6.01(b), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Securityholders. The Trustee shall not give notice of a Default pursuant to Section 6.01(c) until at least sixty (60) days have passed since its occurrence.

Section 7.06. Disqualification; Conflicting Interests. If the Trustee has or shall acquire any conflicting interest within the meaning of the TIA, it shall either eliminate such conflicting interest or resign, to the extent and in the. manner provided by, and subject to the provisions of the TIA and this Indenture.

Section 7.07. Compensation and Indemnity. The Company agrees:

(a) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(b) to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expense, advances and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and

(c) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this trust, including the costs and expenses of defending itself against any claim or liability

in connection with the exercise or performance of any of its powers or duties hereunder.

To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay the principal amount, premium, if any, accrued interest, Redemption Price or Fundamental Change Redemption Price, as the case may be, on particular Securities.

The Company’s payment obligations pursuant to this Section 7.07 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(d) or (e), the expenses are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.08. Replacement of Trustee. The Trustee may resign by so notifying the Company; provided, however, no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 7.08. The Holders of a majority in aggregate principal amount of the Securities at the time outstanding may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

(a) the Trustee fails to comply with, or ceases to be eligible under, Section 7.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint, by resolution of its Board of Directors, a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in aggregate principal amount of the Securities at the time outstanding

may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Section 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trustee business or assets (including the administration of the trust created by this Indenture) to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

Section 7.10. Eligibility; Disqualification. The Trustee (or if a Trustee is a member of a bank holding company, its bank holding company) shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of conditions. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

Section 7.11. Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against the Company (or any such other obligor).

Section 7.12. Reports by Trustee.

(a) The Trustee shall transmit to Holders such reports concerning the Trustee and its actions under this Indenture as may be required pursuant to the TIA at the times and in the manner provided pursuant thereto.

(b) A copy of each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange or market upon which the Securities are listed, with the Commission and with the Company. The Company will notify the Trustee when the Securities are listed on any stock exchange or market.

ARTICLE 8
DISCHARGE OF INDENTURE

Section 8.01. Discharge of Liability on Securities. When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all outstanding Securities have become due and payable and the Company deposits with the Trustee cash and/or

securities, as permitted by the terms hereof, sufficient to pay at Stated Maturity the principal amount of all outstanding Securities (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 7.07, cease to be of further effect. The Trustee shall join in the execution of a document prepared by the Company acknowledging satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and Opinion of Counsel and at the cost and expense of the Company.

Section 8.02. Repayment to the Company. The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, provided, however, that the Trustee or such Paying Agent, before being required to make any such return, shall at the expense of the Company cause to be published once in a newspaper of general circulation in The City of New York or mail to each such Holder notice that such money or securities remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing, any unclaimed money or securities then remaining will be returned to the Company. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

ARTICLE 9
AMENDMENTS

Section 9.01. Without Consent Of Holders. The Company and the Trustee may amend this Indenture or the Securities without the consent of any Securityholder:

(a) to cure any ambiguity, defect or inconsistency;

(b) to comply with Article 5 or Section 10.14;

(c) to provide for uncertificated Securities in addition to certificated Securities so long as such uncertificated Securities are in registered form for purposes of the Internal Revenue Code of 1986, as amended;

(d) to make any change that does not adversely affect the right of any Securityholder; or

(e) to make any change to comply with the TIA, or any amendment thereto, or to comply with any requirement of the SEC in connection with the qualification, if any, of the Indenture under the TIA.

Section 9.02. With Consent of Holders. With the written consent of the Holders of at least a majority in aggregate principal amount of the Securities at the time outstanding, the Company and the Trustee may amend this Indenture or the Securities. However, without the consent of each Securityholder affected, an amendment or supplement to this Indenture or the Securities may not:

(a) make any change to the manner or rate of accrual in connection with interest, reduce the rate of interest referred to in paragraph 1 of the Securities or extend the time for payment of interest on any Security;

(b) reduce the Redemption Price or extend the Stated Maturity;

(d) make any Security payable in money or securities other than that stated in the Security;

(e) make any change in Section 6.04, Section 6.07 or this Section 9.02, except to increase any such percentage;

(f) make any change that adversely affects the right to convert any Security; or

(g) make any change that adversely affects the right to require the Company to redeem the Securities upon a Fundamental Change in accordance with the terms thereof and this Indenture;

and no such amendment or supplement to this Indenture may reduce the aforesaid percentage of Securities whose Holders must consent to any such amendment or supplemental indenture, without the consent of the Holders of all the Securities then outstanding.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment or supplemental indenture, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section 9.02 becomes effective, the Company shall mail to each Holder a notice briefly describing the amendment.

Section 9.03. Compliance with TIA. Every supplemental indenture executed pursuant to this Article shall comply with the TIA as then in effect.

Section 9.04. Revocation and Effect of Consents, Waivers and Actions. Until an amendment, supplemental indenture, waiver or other action becomes effective, a consent to it or any other action by a Holder of a Security hereunder is

a continuing consent by the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same obligation as the consenting Holder’s Security, even if notation of the consent, waiver or action is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent, waiver or action as to such Holder’s Security or portion of the Security if the Trustee receives the notice or revocation before the date the amendment, supplemental indenture, waiver or action becomes effective. After an amendment, supplemental indenture, waiver or action becomes effective, it shall bind every Securityholder.

Section 9.05. Notation on or Exchange of Securities. Securities authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Securities,

Section 9.06. Trustee to Sign Supplemental Indentures. The Trustee shall sign any supplemental indenture authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture the Trustee shall be entitled to receive, and (subject to the provisions of Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that such supplemental indenture is authorized or permitted by this Indenture.

Section 9.07. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

ARTICLE 10
CONVERSION

Section 10.01. Conversion Privilege. A Holder of a Security may convert such Security into Common Stock at any time during the period stated in paragraph 7 of the Securities. The conversion price per share of Common Stock (the “Conversion Price”) shall be that set forth in paragraph 7 in the Securities, subject to adjustment as herein set forth.

A Holder may convert a portion of the principal amount of a Security if the portion is $1,000 or a multiple of $1,000. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security.

Section 10.02. Conversion Procedure. To convert a Security a Holder must satisfy the requirements in paragraph 7 of the Securities. The date on which the Holder satisfies all those requirements is the conversion date (the “Conversion Date”). Securities surrendered for conversion during the period from the close of business on any Regular Record Date to the close of business on the Trading Day immediately prior to the next succeeding Interest Payment Date (the “Interest Period”) shall (except in the case of Securities or portions thereof which have been called for redemption on a Redemption Date within such Interest Period) be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on such Interest Payment Date on the principal amount of Securities being surrendered for conversion. Subject to the provisions of Section 3.07 relating to the payment of Defaulted Interest by the Company, the interest payment with respect to a Security surrendered for conversion during the Interest Period (except in the case of Securities or portions thereof which have been called for redemption on a Redemption Date within the Interest Period) shall be payable on such Interest Payment Date to the Holder of such Securities at the close of business on such Regular Record Date notwithstanding the conversion of such Securities during such Interest Period.

As soon as practicable after the Conversion Date, the Company shall deliver to the Holder, through the Conversion Agent, a certificate for the number of full shares of Common Stock issuable upon the conversion and cash in lieu of any fractional share determined pursuant to Section 10.03. The person in whose name the certificate is registered shall be treated as a stockholder of record on and after the Conversion Date; provided, however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; such conversion shall be at the Conversion Price in effect on the date that such Security shall have been surrendered for conversion, as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security.

No payment or adjustment will be made for dividends on or other distribution with respect to any Common Stock except as provided in this Article 10.

If the Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the conversion shall be based on the total principal amount of the Securities converted.

Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder, a new Security in an authorized denomination equal in principal amount to the unconverted portion of the Security surrendered.

If the last day on which a Security may be converted is a Legal Holiday in a place where a Conversion Agent is located, the Security may be surrendered to that Conversion Agent on the next succeeding day that it is not a Legal Holiday.

Section 10.03. Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Security. Instead, the Company will deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined to the nearest 1/10,000th of a share by multiplying the last reported sale price (determined as set forth in the definition of Current Market Price), on the last Trading Day prior to the Conversion Date, of a full share by the fractional amount and rounding the product to the nearest whole cent.

Section 10.04. Taxes on Conversion. If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificates representing the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which 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.

Section 10.05. Company to Provide Stock. The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve out of its authorized but unissued Common Stock a sufficient number of shares of Common Stock to permit the conversion of the Securities.

All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares or treasury shares, shall be duly and validly issued

and fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

The Company will endeavor promptly to comply with all Federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any, and will endeavor promptly, if permitted by the rules of such exchange, over-the-counter market or other market, to list or cause to have quoted such shares of Common Stock on each national Securities exchange or in the over-the-counter market or such other market on which the Common Stock is then listed or quoted.

Section 10.06. Adjustment for Change in Capital Stock. In case the Company shall (i) pay a dividend, or make a distribution, in shares of its Common Stock, on its Common Stock, (ii) subdivide its outstanding Common Stock into a greater number of shares, or (iii) combine its outstanding Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior thereto shall be adjusted so that the holder of any Security thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock of the Company which he would have owned or have been entitled to receive after the happening of any of the events described above had such Security been converted immediately prior to the happening of such event. If any dividend or distribution of the type described in clause (i) above is not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. An adjustment made pursuant to this Section 10.06 shall become effective immediately after the record date in the case of a dividend and shall become effective immediately after the effective date in the case of subdivision or combination.

Section 10.07. Adjustment for Rights Issue. In case the Company shall issue rights or warrants to all holders of its Common Stock entitling them (for a period expiring within 45 days after the record date mentioned below) to subscribe for or purchase Common Stock at a price per share less than the Current Market Price per share of Common Stock at the record date for the determination of stockholders entitled to receive such rights or warrants, the Conversion Price in effect immediately prior thereto shall be adjusted so that the same shall equal the Conversion Price determined by multiplying the Conversion Price in effect immediately prior to the date of issuance of such rights or warrants by a fraction of which the numerator shall be the number of shares of Common Stock outstanding on the date of issuance of such rights or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered would purchase at such Current Market Price, and of which the denominator shall be the number of shares of Common Stock outstanding on the date of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase. Such adjustment shall be made successively

whenever any such rights or warrants are issued, and shall become effective immediately after the opening of business on the day following the record date for the determination of the 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 Price shall be readjusted to the Conversion Price which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such record date 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, the value of such consideration, if other than cash, to be determined by the Board of Directors.

Section 10.08. Adjustment for Other Distributions. (a) In case the Company shall distribute to all holders of its Common Stock (excluding any distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary) any shares of any class of capital stock of the Company (other than Common Stock) or evidences of its indebtedness or assets (other than cash) or rights or warrants to subscribe for or purchase any of its securities (excluding those referred to in Section 10.07 hereof) (any of the foregoing hereinafter in this Section 10.08(a) called the “Distributed Securities”), then, in each case, the Conversion Price shall be adjusted so that the same shall equal the Conversion Price determined by multiplying the Conversion Price in effect immediately prior to the date of such distribution by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on the record date mentioned below less the fair market value on such record date (as determined by the Board of Directors of the Company, whose determination shall be conclusive, and described in a certificate filed with the Trustee) of the Distributed Securities so distributed applicable to one share of Common Stock, and the denominator shall be the Current Market Price per share of the Common Stock on such record date. Such adjustment shall become effective immediately after the record date for the determination of stockholders entitled to receive such distribution. Notwithstanding the foregoing, in the event the then fair market value (as so determined) of the portion of the Distributed Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the relevant record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Securityholder shall have the right to receive upon conversion the amount of Distributed Securities such Holder would have received had such

Holder converted each Security on such record date. In the event that such distribution is not so paid or made, the Conversion Price shall again be adjusted to the Conversion Price which would then be in effect if such distribution had not been declared. If the Board of Director determines the fair market value of any distribution for purposes of this Section 10.08(a) 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 of the Common Stock.

Notwithstanding the foregoing provisions of this Section 10.08(a), no adjustment shall be made thereunder for any distribution of Distributed Securities if the Company makes proper provision so that each Holder of a Security who converts such Security (or any portion thereof) after the record date for such distribution shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversion, the amount and kind of Distributed Securities that such Holder would have been entitled to receive if such Holder had, immediately prior to such record date, converted such Security into Common Stock, provided that, with respect to any Distributed Securities that are convertible, exchangeable or exercisable, the foregoing provision shall only apply to the extent (and so long as) the Distributed Securities receivable upon conversion of such Security would be convertible, exchangeable or exercisable, as applicable, without any loss of rights or privileges for a period of at least 60 days following conversion of such Security.

(b) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock cash (excluding (x) any quarterly cash dividend on the Common Stock to the extent the aggregate cash dividend per share of Common Stock in any fiscal quarter does not exceed the greater of (A) the amount per share of Common Stock of the next preceding quarterly cash dividend on the Common Stock to the extent such preceding quarterly dividend did not require any adjustment of the Conversion Price pursuant to this Section 10.08(b) (as adjusted to reflect subdivisions or combinations of the Common Stock), and (B) 3.75% of the average of the last reported sales prices of the Common Stock (determined as provided in the definition of Current Market Price) during the ten Trading Days next preceding the date of declaration of such dividend and (y) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary), then, in such case, unless the Company elects to reserve such cash for distribution to the holders of the Securities upon the conversion of the Securities so that any such holder converting Securities will receive upon such conversion, in addition to the shares of Common Stock to which such holder is entitled, the amount of cash which such holder would have received if such holder had, immediately prior to the record date for such distribution of cash, converted its Securities into Common Stock, the Conversion Price shall be decreased so that the same shall equal the Conversion Price determined by multiplying the Conversion Price in effect immediately prior

to the record date by a fraction of which the numerator shall be the Current Market Price of the Common Stock on the record date less the amount of cash so distributed (and not excluded as provided above) applicable to one share of Common Stock, and the denominator shall be such Current Market Price of the Common Stock, such decrease to be effective immediately prior to the opening of business on, the day following the record date; provided, however, that in the event the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Securityholder shall have the right to receive upon conversion the amount of cash such holder would have received had such holder converted each Security on the record date. If such dividend or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If any adjustment is required to be made as set forth in this Section 10.08(b) as a result of a distribution that is a quarterly dividend, such adjustment shall be based upon the amount by which such distribution exceeds the amount of the quarterly cash dividend permitted to be excluded pursuant hereto. If an adjustment is required to be made as set forth in this Section 10.08(b) above as a result of a distribution that is not a quarterly dividend, such adjustment shall be based upon the full amount of the distribution.

(c) In case a tender or exchange offer made by the Company or any Subsidiary of the Company for all or any portion of the Common Stock shall expire and such tender or exchange offer shall involve the payment by the Company or such Subsidiary of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors or, to the extent permitted by applicable law, a duly authorized committee thereof, whose determination shall be conclusive, and described in a resolution of the Board of Directors or such duly authorized committee thereof, as the case may be, at the last time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended)) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, the Conversion Price shall be decreased so that the same shall equal the Conversion Price determined by multiplying the Conversion Price in effect immediately prior to the Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Expiration Time (the shares deemed so accepted up to

any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) on the Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such decrease to become effective immediately prior to the opening of business on the day following the Expiration Time. In the event that 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 Price shall again be adjusted to be the Conversion Price which would then be effect if such tender or exchange offer had not been made.

(d) In case of a tender or exchange offer made by a Person other than the Company or any Subsidiary for an amount which increases the offeror’s ownership of Common Stock to more than 25% of the Common Stock outstanding and shall involve the payment by such person of consideration per share of Common Stock having a fair market value (as determined by the Board of Directors, whose determination shall be conclusive, and described in a resolution of the Board of Directors) at the last time (the “Offer Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange offer (as it shall have been amended) that exceeds the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, and in which, as of the Offer Expiration Time the Board of Directors is not recommending rejection of the offer, the Conversion Price shall be decreased so that the same shall equal the Conversion Price determined by multiplying the Conversion Price in effect immediately prior to the Offer Expiration Time by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered or exchanged shares) on the Offer Expiration Time multiplied by the Current Market Price of the Common Stock on the Trading Day next succeeding the Offer Expiration Time, and the denominator shall be the sum of (x) the fair market value (determined as aforesaid) of the aggregate consideration payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered or exchanged and not withdrawn as of the Offer Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Accepted Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Accepted Purchased Shares) on the Offer Expiration Time and the Current Market Price of the Common Stock on the Trading Day next succeeding the Expiration Time, such decrease to become effective immediately prior to the opening of business on the day following the Offer Expiration Time. In the event that such Person is obligated to purchase shares pursuant to any such tender or exchange offer, but such Person is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Price shall again be adjusted to be

the Conversion Price which would then be in effect if such tender or exchange offer had not been made. Notwithstanding the foregoing, the adjustment described in this Section 10.08(d) shall not be made if as of the Offer Expiration Time, the offering documents with respect to such offer disclose a plan or intention to cause the Company to engage in any transaction described in Article 5.

Section 10.09. When Adjustment May be Deferred. No adjustment in the Conversion Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment.

All calculations under this Article 10 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be.

Section 10.10. When no Adjustment Required. No adjustment need be made for rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest.

No adjustment need be made for a change in the par value or no par value of the Common Stock.

To the extent the Securities become convertible into cash, assets, property or securities (other than capital stock of the Company), no adjustment need be made thereafter as to the cash, assets, property or such securities. Interest will not accrue on the cash.

Section 10.11. Notice of Adjustment. Whenever the Conversion Price is adjusted, the Company shall promptly mail to Securityholders a notice of the adjustment. The Company shall file with the Trustee and the Conversion Agent such notice. The certificate shall, absent manifest error, be conclusive evidence that the adjustment is correct. Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate except to exhibit the same to any Holder desiring inspection thereof.

Section 10.12. Voluntary Decrease. The Company may make such decreases in the Conversion Price, in addition to those required by Sections 10.06, 10.07 and 10.08, 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 decrease the Conversion Price by any amount for any period of time if the period is at least 20 days, the decrease is irrevocable during the period and the Board of Directors

shall have made a determination that such decrease would be in the best interests of the Company, which determination shall be conclusive. Whenever the Conversion Price is so decreased, the Company shall mail to Securityholders and file with the Trustee and the Conversion Agent a notice of the decrease. The Company shall mail the notice at least 15 days before the date the decreased Conversion Price takes effect. The notice shall state the decreased Conversion Price and the period it will be in effect.

Section 10.13. Notice Of Certain Transactions. If:

(a) the Company makes any distribution or dividend that would require an adjustment in the Conversion Price pursuant to Section 10.06, 10.07 or 10.08; or

(b) the Company takes any action that would require a supplemental indenture pursuant to Section 10.14; or

then the Company shall mail to Securityholders and file with the Trustee and the Conversion Agent a notice referencing this Section 10.13 and stating the proposed record date for a dividend or distribution or the proposed effective date of a subdivision, combination, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up, and if applicable, the new Conversion Price. The Company shall file and mail the notice at least 15 days before such date. Failure to file or mail the notice or any defect in it shall not affect the validity of the transaction. Unless and until the Trustee shall receive a notice pursuant to this Section 10.13, it shall not be deemed to have knowledge of any event required to be described in a notice pursuant to this Section 10.13.

Section 10.14. Effect of Reclassification, Consolidation, Merger or Sale. If any of the following events occur, namely (i) any reclassification or change of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation, merger or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, or (iii) any sale or conveyance of the properties and assets of the Company as, or substantially as, an entirety to any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture providing that each Security shall be convertible into the kind and amount of shares of stock and other securities or property or assets (including cash) receivable upon such reclassification, change, consolidation, merger, combination, sale or conveyance by a holder of a number of shares of Common Stock issuable upon conversion of such Securities

immediately prior to such reclassification, change, consolidation, merger, combination, sale or conveyance. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article.

The Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Securities at his address appearing on the Security register provided for in Section 2.03 of this Indenture.

The above provisions of this Section shall similarly apply to successive reclassifications, consolidations, mergers, combinations, and sales.

If this Section applies, neither Section 10.06, 10.07 nor 10.08 applies.

Section 10.15. Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to Section 10.03, 10.06, 10.07, 10.08, 10.09, 10.10, 10.14 or 10.17 is conclusive.

Section 10.16. Trustee’s Adjustment Disclaimer. The Trustee has no duty to determine when an adjustment under this Article 10 should be made, how it should be made or what it should be. The Trustee has no duty to determine whether a supplemental indenture under Section 10.14 need be entered into or whether any provisions of any supplemental indenture are correct. The Trustee shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. The Trustee shall not be responsible for the Company’s failure to comply with this Article 10. Each Conversion Agent shall have the same protection under this Section 10.16 as the Trustee.

Section 10.17. Simultaneous Adjustment. In the event that this Article 10 requires adjustments to the Conversion Price under more than one of Sections 10.06, 10.07, 10.08(a) or 10.08(b), and the record dates for the distributions giving rise to such adjustments shall occur on the same date, then such adjustments shall be made by applying, first, the provisions of Section 10.08(a), second, the provisions of Section 10.08(b), third the provisions of Section 10.06 and, fourth, the provisions of Section 10.07.

Section 10.18. Successive Adjustments. After an adjustment to the Conversion Price under this Article 10, any subsequent event requiring an adjustment under this Article 10 shall cause an adjustment to the Conversion Price as so adjusted.

Section 10.19. Rights Issued in Respect of Common Stock Issued Upon Conversion. Each share of Common Stock issued upon conversion of Securities pursuant to this Article 10 shall be entitled to receive the appropriate number of

Rights (as defined below), if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as provided by and subject to the terms of the agreement governing such Rights (the “Rights Agreement”) as in effect at the time of such conversion. If the Rights are separated from the Common Stock in accordance with the provisions of the Rights Agreement such that the Holders of Securities would thereafter not be entitled to receive any such Rights in respect to the Common Stock issuable upon conversion of such Securities, the Conversion Price will be adjusted as provided in Section 10.08(a) on the separation date; provided that if such Rights expire, terminate or are redeemed by the Company, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such separation had not occurred. In lieu of any such adjustment, the Company may amend the Rights Agreement to provide that upon conversion of the Securities the Holders will receive, in addition to the Common Stock issuable upon such conversion, the Rights which would have attached to such shares of Common Stock if the Rights had not become separated from the Common Stock pursuant to the provisions of the Rights Agreement.

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”):

(a) are deemed to be transferred with such shares of Common Stock,

(b) are not exercisable, and

(“Rights”) shall not be deemed distributed for purposes of Section 10.08(a) until the occurrence of the earliest Trigger Event. In addition, in the event of any distribution of rights or warrants, or any Trigger Event with respect thereto, that shall have resulted in an adjustment to the Conversion Price under Section 10.08(a), (1) in the case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder of Common Stock with respect to such rights or warrants (assuming such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of any such rights or warrants all of which shall have expired without exercise by any holder thereof, the Conversion Price shall be readjusted as if such issuance had not occurred.

Section 10.20. General Considerations. Whenever successive adjustments to the Conversion Price are called for pursuant to this Article 10, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Article and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

6.50% SENIOR CONVERTIBLE NOTE DUE 2009

	CUSIP

6.50% SENIOR CONVERTIBLE NOTE DUE 2009

1. Interest

This Security shall bear interest at 6.50% per annum in the manner set forth in the Indenture and the face of this Security. In the event that principal hereof or any portion of such principal is not paid when due (whether upon acceleration pursuant to Section 6.02 of the Indenture, upon the date set for payment of the Redemption Price pursuant to paragraph 5 hereof, upon the date set for payment of a Fundamental Change Redemption Price pursuant to paragraph 6 hereof or upon the Stated Maturity of this Security), then in each such case the overdue amount shall bear interest at the rate of 6.50% per annum, compounded semiannually (to the extent that the payment of such interest shall be legally enforceable), which interest shall accrue from the date such overdue amount was due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand.

2. Method of Payment

Subject to the terms and conditions of the Indenture, the Company will make payments in respect of the Securities to the persons who are registered Holders of Securities at the close of business on the Redemption Date, Fundamental Change Repurchase Date or Stated Maturity, as the case may be. Holders must surrender Securities to a Paying Agent to collect such payments in respect of the Securities. 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. However, the Company may make such cash payments by check mailed to the address of, or by wire transfer to the account of, the person entitled to such payment.

3. Paying Agent, Conversion Agent and Registrar

Initially, U.S. Bank National Association, a national banking association (the “Trustee”), will act as Paying Agent, Conversion Agent and Registrar. The Company may appoint and change any Paying Agent, Conversion Agent, Registrar or co-registrar without notice, other than notice to the Trustee. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent, Conversion Agent, Registrar or co-registrar.

A-4

4. Indenture

The Company issued the Securities under an Indenture dated as of , 2003 (the “Indenture”), between the Company and the Trustee. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture for a statement of those terms.

The Securities are general unsecured obligations of the Company limited to $120,000,000 aggregate principal amount (subject to Sections 2.02 and 2.07 of the Indenture).

5. Redemption at the Option of the Company

Prior to the second anniversary of the original issuance of the Securities, the Securities will not be redeemable at the option of the Company. Beginning on the second anniversary of the original issuance of the Securities, the Company may redeem the Securities for cash as a whole at any time, or from time to time in part, upon not less than 10 days’ nor more than 60 days’ notice at a price equal to 100% of the principal amount (the “Redemption Price”) thereof, together with accrued and unpaid interest to, but excluding, the Redemption Date, provided that during the year beginning on the second anniversary of the original issuance of the Securities, the Company may only redeem the Securities if the Closing Price of the Company’s Common Stock has been at least 150% of the then-applicable Conversion Price for the 20 consecutive Trading Days ending two Trading Days prior to the notice of redemption.

If any Redemption Date is an Interest Payment Date, then the interest payable on such date shall be paid to the Holder of the Security on the next preceding Regular Record Date. No Securities may be redeemed by the Company if an Event of Default with respect to the payment of interest on the Securities has occurred and is continuing.

No sinking fund is provided for the Securities.

Notice of redemption at the option of the Company will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Securities to be redeemed at the Holder’s registered address. If money sufficient to pay the Redemption Price, together with accrued interest to, but excluding, the Redemption Date, of all Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent prior to or on the Redemption Date, on and after such date interest ceases to accrue on such Securities or portions thereof. Securities in denominations larger than $1,000 of principal amount may be redeemed in part but only in multiples of $1,000 of principal amount.

A-5

6. Redemption at the Option of the Holder Upon a Fundamental Change

(a) At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to redeem the Securities held by such Holder on the date (the “Fundamental Change Repurchase Date”) (or if such date is not a Business Day, the next succeeding Business Day) that is 45 days after the date of the Company’s notice of such Fundamental Change (as defined in the Indenture) occurring on or prior to July 1, 2009 at 100% of the principal amount. In each case, the Company shall also pay accrued but unpaid interest, if any, on such Securities to, but excluding, the Fundamental Change Repurchase Date; provided that if such Fundamental Change Repurchase Date is an Interest Payment Date, then the interest payable on such date shall be paid to the Holder of the Security on the next preceding Regular Record Date. Securities in denominations larger than $1,000 of principal amount may be redeemed in part in connection with a Fundamental Change, but only in multiples of $1,000 of principal amount.

(b) Holders have the right to withdraw any Fundamental Change Redemption Notice by delivering to the Paying Agent a written notice of withdrawal in accordance with the provisions of the Indenture.

(c) If cash sufficient to pay the Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, of all Securities or portions thereof to be purchased as of the Fundamental Change Repurchase Date is deposited with the Paying Agent on or prior to the Fundamental Change Repurchase Date, interest ceases to accrue on such Securities (or portions thereof) on and after the Fundamental Change Repurchase Date, and the Holder thereof shall have no other rights as such (other than the right to receive the Fundamental Change Redemption Price, together with accrued interest to, but excluding, the Fundamental Change Repurchase Date, upon surrender of such Security).

7. Conversion

Subject to the next two succeeding sentences, a Holder of a Security may convert it into Common Stock of the Company at any time after issuance and before the close of business on July 1, 2009. If the Security is called for redemption, the Holder may convert it at any time before the close of the last Trading Day prior to the Redemption Date. In the event the Security is surrendered during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the close of business on the Trading Day immediately preceding the next succeeding Interest Payment Date (except in the case of Security to be redeemed within such period), such Securities must be accompanied by payment in New York Clearing House funds or other funds acceptable to the Company of an amount equal to the interest payable on

A-6

such Interest Payment Date on the principal amount of this Security then being converted. Subject to the aforesaid requirement for payment and, in the case of a conversion after the Regular Record Date next preceding any Interest Payment Date and on or before such Interest Payment Date, to the right of the Holder of this Security (or any Predecessor Security) of record at such Regular Record Date to receive an installment of interest payable on such Interest Payment Date (except in the case of Securities whose Maturity is prior to such Interest Payment Date), no payment or adjustment is to be made on conversion for interest accrued hereon or for dividends on the Common Stock issued on conversion. A Security in respect of which a Holder has delivered a notice of exercise of the option to redeem such Security in the event of a Fundamental Change may be converted only if the notice of exercise is withdrawn in accordance with the terms of the Indenture.

The initial Conversion Price is $3.00 per share of Common Stock, subject to adjustment in certain events described in the Indenture. The Company will deliver cash or a check in lieu of any fractional share of Common Stock.

To convert a Security a Holder must (1) complete and manually sign the conversion notice on the back of the Security (or complete and manually sign a facsimile of such notice) and deliver such notice to the Conversion Agent, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, the Company or the Trustee and (4) pay any transfer or similar tax, if required.

A Holder may convert a portion of a Security if the principal amount of such portion is $1,000 or a multiple of $1,000. No payment or adjustment will be made for dividends on the Common Stock except as provided in the indenture.

The Conversion Price is subject to adjustment as provided in the Indenture. In addition, in the case of (i) any reclassification of the Common Stock, or (ii) a consolidation or merger involving the Company or a sale or conveyance to another corporation of the property 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 be entitled to receive stock, securities, other property or assets (including cash) with respect to or in exchange for such Common Stock, as set forth in the Indenture, or upon certain distributions described in the Indenture, the right to convert a Security into Common Stock may be changed; as set forth in the Indenture, into a right to convert it into securities, cash or other assets of the Company or another person.

8. Conversion Arrangement on Call for Redemption

Any Securities called for redemption, unless surrendered for conversion before the close of business on the last Trading Day prior to the Redemption Date,

A-7

may be deemed to be purchased from the Holders of such Securities at an amount not less than the Redemption Price, together with accrued interest to, but excluding the Redemption Date, by one or more investment bankers or other purchasers who may agree with the Company to purchase such Securities from the Holders, to convert them into Common Stock of the Company and to make payment for such Securities to the Trustee in trust for such Holders.

9. Denominations; Transfer; Exchange

The Securities are in registered form, without coupons, in denominations of $1,000 of principal amount and multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities in respect of which a Fundamental Change Redemption Notice has been given and not withdrawn (except, in the case of a Security to be purchased in part, the portion of the Security not to be purchased) or any Securities for a period of 15 days before a selection of Securities to be redeemed.

10. Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of this Security for all purposes.

11. Unclaimed Money or Securities

The Trustee and the Paying Agent shall return to the Company upon written request any money or securities held by them for the payment of any amount with respect to the Securities that remains unclaimed for two years, provided, however, that the Trustee or such Paying Agent, before being required to make any such return, shall at the expense of the Company cause to be published once in a newspaper of general circulation in The City of New York or mail to each such Holder notice that such money or securities remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing, any unclaimed money or securities then remaining will be returned to the Company. After return to the Company, Holders entitled to the money or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

A-8

12. Amendment; Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Securities may be amended with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities at the time outstanding and (ii) certain defaults or noncompliance with certain provisions may be waived with the written consent of the Holders of a majority in aggregate principal amount of the Securities at the time outstanding. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company and the Trustee may amend the Indenture or the Securities to cure any ambiguity, defect or inconsistency, or to comply with Article 5 or Section 10.14 of the Indenture, to provide for uncertificated Securities in addition to or in place of certificated Securities or to make any change that does not adversely affect the rights of any Securityholder or to comply with any requirement of the SEC in connection with the qualification of the Indenture under the TIA.

13. Defaults and Remedies

Under the Indenture, Events of Default include (i) default in payment of the principal amount, Redemption Price or Fundamental Change Redemption Price, as the case may be, in respect of the Securities when the same becomes due and payable; (ii) default for 30 days in the payment of any installment of interest on the Securities; (iii) failure by the Company to comply with other agreements in the Indenture or the Securities, subject to notice and lapse of time; (iv) an event of default under the Secured Credit Facility, the Old Notes Indenture or the New Indenture shall have occurred that results in the principal amount of and accrued interest on that debt becoming immediately due and payable, and (v) certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate principal amount of the Securities at the time outstanding, may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Securities being declared due and payable immediately upon the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities at the time outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of amounts specified in clause (i) or (ii) above) if it determines that withholding notice is in their interests.

A-9

14. Trustee Dealings with the Company

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

15. No Recourse Against Others

A director, officer, employee or stockholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

16. Authentication

This Security shall not be valid until an authorized officer of the Trustee manually signs the Trustee’s Certificate of Authentication on the other side of this Security.
