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 signatory, 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 the Securities for original issuance in an aggregate principal amount of up to $120,000,000 upon one or more Company Orders without any further action by the Company (other than as contemplated below and in Section 14.4 and Section 14.5). The aggregate principal amount due at the Stated Maturity of the Securities outstanding at any time may not exceed the amount set forth in the foregoing sentence except as provided in Section 2.7. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall receive and shall be fully protected in relying upon:

(a) a copy of the Board Resolution in or pursuant to which the terms and form of the Securities were established, the issuance and sale of the Securities was authorized, this Indenture was authorized and specified Officers were authorized to establish the form and determine the terms of the Securities and the form of this Indenture, to execute the Securities and this Indenture on behalf of the Company and to take any other necessary actions relating thereto and evidence of any actions taken by authorized Officers pursuant to that Board Resolution, certified by the Secretary, an Assistant Secretary or a Vice President of the Company to have been duly adopted by the Board of Directors or taken by any authorized Officer and to be in full force and effect as of the date of such certificate; and

(b) an Officers’ Certificate delivered in accordance with Section 14.4 and Section 14.5.

(c) an Opinion of Counsel delivered in accordance with Section 14.4 and Section 14.5.

The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent.

The Securities shall be issued only in registered form without coupons and only in denominations of $1,000 of principal amount and any integral multiple of $1,000.

Section 2.3. Registrar, Paying Agent and Conversion Agent.

Pursuant to Section 6.5, the Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (“Registrar”), an office or agency where Securities may be presented for redemption, repurchase or payment (“Paying Agent”), an office or agency where Securities may be presented for conversion (“Conversion Agent”) and an

13

office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. Pursuant to Section 6.5, the Company shall at all times maintain a Registrar, Paying Agent, Conversion Agent and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, New York City. The Registrar shall keep a register of the Securities (the “Register”) and of their transfer and exchange.

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, including any named pursuant to Section 6.5. The term Conversion Agent includes any additional conversion agent, including any named pursuant to Section 6.5.

The Company shall enter into an appropriate limited agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar (in each case, if such Registrar, agent or co-registrar is a Person other than the Trustee). Each such agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 9.7. The Company or any Subsidiary or an Affiliate of either of them may act as Paying Agent, Registrar, Conversion Agent or co-registrar and, if the Company fails to maintain a Conversion Agent, the Company shall act as such.

The Company hereby initially appoints The Bank of New York as Registrar, Paying Agent and Conversion Agent in connection with the Securities. The initial office of the Registrar, Paying Agent and Conversion Agent shall be the office of the Trustee that is located in the Borough of Manhattan, New York City, which office on the date hereof is 101 Barclay Street, New York, New York 10286, Attention: Corporate Trust Division - Corporate Finance Unit.

Section 2.4. Paying Agent to Hold Assets in Trust.

Except as otherwise provided herein, prior to 10:00 a.m., New York City time, on each due date of payments in respect of any Security, the Company shall deposit with the Paying Agent, cash (in immediately available funds if deposited on the due date), sufficient to make such payments when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash and Applicable Stock held by the Paying Agent for the making of payments in respect of the Securities and shall notify the Trustee of any default by the Company in making any such payment. The Company at any time may require a Paying Agent to pay all cash held by it to the Trustee, and to account for any funds disbursed by it, and the Trustee may at any time during the continuance of any such default, upon the written request to the Paying Agent, require such Paying Agent to forthwith pay to the Trustee all cash so held in trust. Upon doing so, the Paying Agent shall have no further liability for such cash.

Section 2.5. Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall cause to be furnished to the Trustee on or before each semiannual interest payment date and at such other times as the Trustee may request in writing a list in such

14

form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

Section 2.6. Transfer and Exchange.

(a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to the Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate, each in the form included in Exhibit A attached hereto and in form satisfactory to the Registrar and each duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained for such purpose pursuant to Section 2.3, the Company shall execute, and the Trustee shall authenticate, Securities of a like aggregate principal amount at the Registrar’s request. Any transfer or exchange shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of the Securities from the Holder requesting such transfer or exchange.

Neither the Company, the Registrar nor the Trustee shall be required to exchange or register a transfer of (i) any Securities selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed), or (ii) any Securities in respect of which a Purchase Notice or a Fundamental Change Purchase Notice has been given and not withdrawn by the Holder thereof in accordance with the terms of this Indenture (except, in the case of Securities to be repurchased in part, the portion thereof not to be repurchased), or (iii) any Securities surrendered for conversion (except, in the case of Securities to be converted in part, the portion thereof not to be converted). All Securities issued upon any transfer or exchange of Securities in accordance with this Indenture shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange.

(b) Any Registrar appointed pursuant to Section 2.3 shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities.

(c) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

15

Section 2.7. Replacement Securities.

If (a) any mutilated Security is surrendered to the Company, the Registrar or the Trustee, or (b) the Company, the Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the Registrar and the Trustee such security or indemnity as may be requested by them to save each of them harmless, then, in the absence of notice to the Company, the Registrar 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 certificate 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 III or repurchased by the Company pursuant to Article V, the Company in its discretion may, instead of issuing a new Security, pay, redeem or repurchase such Security, as the case may be.

Upon the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee or the Registrar) connected therewith.

Every new Security issued pursuant to this Section 2.7 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 2.7 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 2.8. Outstanding Securities; Determinations of Holders’ Action.

Securities outstanding at any time are all the Securities authenticated by the Trustee, except for:

(a) those cancelled by it,

(b) those paid, redeemed or repurchased pursuant to Section 2.7,

(c) those delivered to it for cancellation, and

(d) those described in this Section 2.8 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, waiver, or other Act 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

16

shall be protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other Act, only Securities which a Responsible Officer of the Trustee actually 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.

If a Security is replaced pursuant to Section 2.7, the replaced Security ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser unaware that such Security has been replaced.

If the Paying Agent holds, in accordance with the terms of this Indenture, prior to 10:00 a.m., New York City time, on a Redemption Date, a Purchase Date, a Fundamental Change Purchase Date or Stated Maturity, as the case may be, cash or securities, if permitted hereunder, sufficient to pay Securities payable on that date, then on such Redemption Date, Purchase Date, Fundamental Change Purchase Date or Stated Maturity, as the case may be, such Securities shall cease to be outstanding and interest and Additional Interest, if any, on such Securities shall cease to accrue.

If a Security is converted in accordance with Article XII, then from and after the time of conversion on the date of conversion, such Security shall cease to be outstanding and interest and Additional Interest, if any, on such Security shall cease to accrue.

Section 2.9. 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 shall 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 2.3, 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 and subject to the same limitations under this Indenture as definitive Securities.

Section 2.10. Cancellation.

All Securities surrendered for payment, repurchase by the Company pursuant to Article V, 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 cancelled by it or, if surrendered to the Trustee, shall be promptly cancelled 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 cancelled by the Trustee. The Company may not issue new

17

Securities to replace Securities it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article XII. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 2.10, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of by the Trustee in accordance with the Trustee’s customary procedure.

Section 2.11. Persons Deemed Owners.

Prior to due presentment of a Security for registration of transfer, the Company, the Trustee, any Paying Agent and any agent of the Company, the Trustee or the Paying Agent 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 of, Redemption Price, Purchase Price or Fundamental Change Purchase Price, and interest and Additional Interest, if any, on, the Security, for the purpose of receiving cash or Applicable Stock upon conversion and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

Section 2.12. Additional Transfer and Exchange Requirements.

(a) Transfer and Exchange of Global Securities.

18

(b) Transfer and Exchange of Certificated Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities in accordance with Section 2.12(a)(i), and, on or after such event, Certificated Securities are presented by a Holder to the Registrar with a request:

(x) to register the transfer of the Certificated Securities to a person who shall take delivery thereof in the form of Certificated Securities only; or

(y) to exchange such Certificated Securities for an equal principal amount of Certificated Securities of other authorized denominations,

such Registrar shall register the transfer or make the exchange as requested; provided, however, that the Certificated Securities presented or surrendered for register of transfer or exchange:

(i)             shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.6; and

(ii)          in the case of a Restricted Certificated Security, such request shall be accompanied by the following additional information and documents, as applicable:

(A)           if such Restricted Certificated Security is being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, or such Restricted Certificated Security is being transferred to the Company or a Subsidiary of the Company, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or

(B)             if such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB in accordance with Rule 144A or pursuant to an effective registration statement under

19

the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate).

(c) Transfer of a Beneficial Interests in a Restricted Global Security for a Beneficial Interest in an Unrestricted Global Security. Any person having a beneficial interest in a Restricted Global Security may upon request, subject to the Applicable Procedures, transfer such beneficial interest to a person who is required or permitted to take delivery thereof in the form of an Unrestricted Global Security. Upon receipt by the Trustee of written instructions, or such other form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any person having a beneficial interest in a Restricted Global Security and the following additional information and documents in such form as is customary for the Depositary from the Depositary or its nominee on behalf of the person having such beneficial interest in the Restricted Global Security (all of which may be submitted by facsimile or electronically):

(i)             if such beneficial interest is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate); or

(ii)          if such beneficial interest is being transferred pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144, a certification to that effect from the Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Trustee so requests, a customary Opinion of Counsel.

The Trustee, as the Registrar, shall reduce or cause to be reduced the aggregate principal amount of the Restricted Global Security by the appropriate principal amount and shall increase or cause to be increased the aggregate principal amount of the Unrestricted Global Security by a like principal amount. Such transfer shall otherwise be effected in accordance with the Applicable Procedures. If no Unrestricted Global Security is then outstanding, the Company shall execute and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly), authenticate and deliver an Unrestricted Global Security.

(d) Transfers of Certificated Securities for Beneficial Interest in Global Securities. In the event that Certificated Securities are issued in exchange for beneficial interests in Global Securities and, thereafter, the events or conditions specified in Section 2.12(a)(i) which required such exchange shall cease to exist, the Company shall mail notice to the Trustee and to the Holders stating that Holders may exchange Certificated Securities or interests in Global Securities by complying with the procedures set forth in this Indenture and briefly describing such procedures and the events or circumstances requiring

20

that such notice be given. Thereafter, if Certificated Securities are presented by a Holder to a Registrar with a request:

(x) to register the transfer of such Certificated Securities to a person who shall take delivery thereof in the form of a beneficial interest in a Global Security, which request shall specify whether such Global Security shall be a Restricted Global Security or an Unrestricted Global Security, or

(y) to exchange such Certificated Securities for an equal principal amount of beneficial interests in a Global Security, which beneficial interests shall be owned by the Holder transferring such Certificated Securities (provided that in the case of such an exchange, Restricted Certificated Securities may be exchanged only for Restricted Global Securities and Unrestricted Certificated Securities may be exchanged only for Unrestricted Global Securities), the Registrar shall register the transfer or make the exchange as requested by canceling such Certificated Security and causing, or directing the Registrar to cause, the aggregate principal amount of the applicable Global Security to be increased accordingly and, if no such Global Security is then outstanding, the Company shall issue and the Trustee shall, upon receipt of a Company Order (which the Company agrees to deliver promptly) authenticate and deliver a new Global Security; provided, however, that the Certificated Securities presented or surrendered for registration of transfer or exchange:

(1)          shall be duly endorsed or accompanied by a written instrument of transfer in accordance with the proviso to the first paragraph of Section 2.6;

(2)          in the case of a Restricted Certificated Security to be transferred for a beneficial interest in an Unrestricted Global Security, such request shall be accompanied by the following additional information and documents, as applicable:

(i)                  if such Restricted Certificated Security is being transferred pursuant to an effective registration statement under the Securities Act, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate); or

(ii)               if such Restricted Certificated Security is being transferred pursuant to an exemption from the registration requirements of the Securities Act in accordance with Rule 144, a certification to that effect from such Holder (in substantially the form set forth in the Transfer Certificate) and, if the Company or the Registrar so requests, a customary Opinion of Counsel;

21

(3)          in the case of a Restricted Certificated Security to be transferred or exchanged for a beneficial interest in a Restricted Global Security, such request shall be accompanied by a certification from such Holder (in substantially the form set forth in the Transfer Certificate) to the effect that such Restricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB (which, in the case of an exchange, shall be such Holder) in accordance with Rule 144A.

(4)          in the case of an Unrestricted Certificated Security to be transferred or exchanged for a beneficial interest in a Restricted Global Security, such request shall be accompanied by a certification from such Holder (in substantially, the form set forth in the Transfer Certificate) to the effect that such Unrestricted Certificated Security is being transferred to a person the Holder reasonably believes is a QIB (which, in the case of an exchange, shall be such Holder) in accordance with Rule 144A.

(e) Legends.

(1)          Except as permitted by the following paragraphs (2), (3) and (4), each Global Security and Certificated Security (and all Securities issued in exchange therefor or upon registration of transfer or replacement thereof) shall bear a legend in substantially the form called for by footnote 2 to Exhibit A and footnote 1 to Exhibit B attached hereto (each a “Transfer Restricted Security”), for so long as it is required by this Indenture to bear such legend. Each Transfer Restricted Security shall have attached thereto a certificate (a “Transfer Certificate”) in substantially the form called for by footnote 3 to Exhibit A attached hereto.

(2)          Upon any sale or transfer of a Transfer Restricted Security (x) after the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act, (y) pursuant to Rule 144 or (z) pursuant to an effective registration statement under the Securities Act:

(i)             in the case of any Restricted Certificated Security, any Registrar shall permit the Holder thereof to exchange such Restricted Certificated Security for an Unrestricted Certificated Security, or (under the circumstances described in Section 2.12(e)) to transfer such Restricted Certificated Security to a transferee who shall take such Security in the form

22

of a beneficial interest in an Unrestricted Global Security, and in each case shall rescind any restriction on the transfer of such Security; provided, however, that the Holder of such Restricted Certificated Security shall, in connection with such exchange or transfer, comply with the other applicable provisions of this Section 2.12; and

(ii)          in the case of any beneficial interest in a Restricted Global Security, the Trustee shall permit the beneficial owner thereof to transfer such beneficial interest to a transferee who shall take such interest in the form of a beneficial interest in an Unrestricted Global Security and shall rescind any restriction on transfer of such beneficial interest; provided, that such Unrestricted Global Security shall continue to be subject to the provisions of Section 2.12(a)(ii); and provided, further, that the owner of such beneficial interest shall, in connection with such transfer, comply with the other applicable provisions of this Section 2.12.

(3)          Upon the exchange, registration of transfer or replacement of Securities not bearing the legend described in paragraph (1) above, the Company shall execute, and the Trustee upon receipt of a Company Request shall authenticate and deliver Securities that do not bear such legend and that do not have a Transfer Certificate attached thereto.

(4)          After the expiration of the holding period pursuant to Rule 144(k) of the Securities Act, the Company shall remove any restriction of transfer on such Security, and the Company shall execute, and the Trustee upon receipt of a Company Request shall authenticate and deliver Securities that do not bear such legend and that do not have a Transfer Certificate attached thereto.

(5)          Until the expiration of the holding period applicable to sales of the Securities under Rule 144(k) of the Securities Act or a transfer pursuant to Rule 144 or pursuant to an effective registration statement under the Securities Act, the Applicable Stock issued upon conversion of the Securities shall bear the legend in substantially the form called for by Exhibit B attached hereto.

(f) Transfers to the Company. Nothing contained in this Indenture or in the Securities shall prohibit the sale or other transfer of any Securities (including

23

beneficial interests in Global Securities) to the Company or any of its Subsidiaries. The Company shall ensure that if any such securities shall be reissued, such reissuance shall comply with applicable law and any securities reissued as Transfer Restricted Securities shall be assigned a different “CUSIP” number than any other securities.

(g) Amendments to Rule 144(k). Notwithstanding any other provision in this Indenture, if Rule 144(k) as promulgated under the Securities Act is amended to shorten the two-year period under Rule 144(k), then the references to “two years” in the restrictive legend of each Transfer Restricted Security and footnote one to Exhibit A shall be deemed to refer to such shorter period, from and after receipt by the Trustee of the documents described in Section 2.12(e)(2) from the Company or from a Holder of a Transfer Restricted Security; provided that, a Transfer Restricted Security shall not be deemed to refer to such shorter period if to do so would be prohibited by, or would otherwise cause a violation of, the U.S. federal securities laws applicable at the time. As soon as practicable after a Responsible Officer of the Company receives notice of the effectiveness of any such amendment to shorten the two-year period under Rule 144(k), unless causing the Transfer Restricted Securities to refer to such shorter period would otherwise be prohibited by, or would otherwise cause a violation of, the U.S. federal securities laws applicable at the time, the Company will provide to the Trustee the documents described in Section 2.12(e)(2) respecting the effectiveness of such amendment.

Section2.13. CUSIP Numbers.

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

Section2.14. Ranking.

The Company agrees, and each holder of Securities by accepting the same agrees, that the indebtedness of the Company arising under or in connection with this Indenture and every outstanding Security issued under this Indenture from time to time constitutes and shall constitute a subordinate unsecured general obligation of the Company. The Securities will be subordinated in right of payment to all other existing and future Senior Indebtedness of the Company as provided in Section 4.1 hereof. Notwithstanding the foregoing, nothing in this Section 2.14 shall impair the claims of, or payments to, the Trustee under or pursuant to Sections 8.10 and 9.07, and the Trustee’s rights to compensation, indemnification and reimbursement of expenses under Sections 8.10 and 9.07 are not subordinated.

24

ARTICLE III

REDEMPTION

Section 3.1. The Company’s Right to Redeem; Notice to Trustee.

Prior to February 18, 2009, the Securities shall not be redeemable at the Company’s option. On or after February 18, 2009, the Company, at its option, may redeem the Securities in accordance with this Article III for cash at any time as a whole, or from time to time in part, at the Redemption Price.

In the event that the Company elects to redeem the Securities on a date that is after any Regular Record Date but on or before the corresponding Interest Payment Date, the Company shall be required to pay any accrued and unpaid interest and Additional Interest, if any, to the holder of the redeemed Security and not the Holder on the corresponding Regular Record Date.

If the Company elects to redeem Securities, it shall notify the Trustee in writing of the Redemption Date, the principal amount of Securities to be redeemed and the Redemption Price. The Company shall give this notice to the Trustee by a Company Order at least 30 days before the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee).

Section 3.2. Selection of Securities to Be Redeemed.

If fewer than all of the outstanding Securities are to be redeemed, unless the procedures of the Depositary provide otherwise, the Trustee shall select the Securities to be redeemed by lot or on a pro rata basis or by another method the Trustee, in its discretion, considers fair and appropriate. The Trustee shall make the selection within five Business Days after it receives the notice provided for in Section 3.1 from outstanding Securities not previously called for redemption.

Securities and portions of Securities that the Trustee selects shall be in principal amounts of $1,000 or an integral 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 the Securities to be redeemed.

Securities and portions of Securities that are to be redeemed are convertible by the Holder until 5:00 p.m., New York City time, on the second Business Day immediately preceding the Redemption Date. 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 3.3. Notice of Redemption.

At least 20 calendar days but not more than 60 calendar 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 of redemption shall identify the Securities to be redeemed and shall state:

(a) the Redemption Date;

25

(b) the Redemption Price;

(c) the Conversion Rate and any adjustments thereto;

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

(e) that Securities called for redemption may be converted at any time prior to 5:00 p.m., New York City time, on the second Business Day preceding the Redemption Date;

(f) that Holders who want to convert their Securities must satisfy the requirements set forth in Article XII;

(g) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

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

(i) that, unless the Company defaults in making payment of such Redemption Price, interest and Additional Interest, if any, on Securities called for redemption shall cease to accrue on and after the Redemption Date;

(j) the CUSIP number(s) of the Securities; and

(k) any other information the Company wants to present.

At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of redemption must be given to Holders in accordance with this Section 3.3; provided, further, that the text of the notice of redemption shall be prepared by the Company.

Section 3.4. 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, except for Securities which are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Securities shall be paid at the Redemption Price.

Section 3.5. Deposit of Redemption Price.

Prior to 10:00 a.m., New York City time, on the applicable 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 acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.4) an amount of cash (in immediately available funds if deposited on the Redemption

Date) sufficient to pay the aggregate Redemption Price of all Securities or portions thereof which are to be redeemed as of such Redemption Date other than Securities or portions of Securities called for redemption which on or prior thereto have been delivered by the Company to the Trustee for cancellation or have been converted.

If the Paying Agent holds, in accordance with the terms hereof, at 10:00 a.m., New York City time, on the applicable Redemption Date, cash sufficient to pay the Redemption Price of any Securities for which notice of redemption is given, then, on such Redemption Date, such Securities shall cease to be outstanding and interest and Additional Interest, if any, on such Securities shall cease to accrue, whether or not such Securities are delivered to the Paying Agent, and the rights of the Holders in respect thereof shall terminate (other than the right to receive the Redemption Price upon delivery of such Securities).

Section 3.6. Securities Redeemed in Part.

Any Certificated Security which is to be redeemed only in part shall be surrendered at the office of the Paying Agent and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to the unredeemed portion of the Security surrendered.

Section 3.7. Repayment to the Company.

To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.5 exceeds the aggregate Redemption Price of the Securities or portions thereof which the Company is redeeming as of the Redemption Date, then, promptly after the Redemption Date, the Paying Agent shall return any such excess to the Company together with interest, if any, thereon.

Section 3.8. No Sinking Fund.

The Securities shall not have a sinking fund.

ARTICLE IV

SUBORDINATION

Section 4.1. Agreement of Subordination.

The Company agrees, and each holder of Securities by accepting the same agrees, that the Indebtedness evidenced by the Securities is subordinated in right of payment (to the extent and in the manner provided in this Article IV) to the prior payment in full in cash or payment satisfactory to holders of Senior Indebtedness of all Senior Indebtedness (whether outstanding on the date hereof or hereafter created, incurred or assumed), and that the subordination is for the benefit of the holders of Senior Indebtedness.

Section 4.2. Liquidation; Dissolution; Bankruptcy.

Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding

27

relating to the Company or its property, in an assignment for the benefit of creditors or any marshaling of the Company’s assets and liabilities:

(a) holders of Senior Indebtedness shall be entitled to receive payment in full of all Obligations due in respect of such Senior Indebtedness (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Indebtedness) in cash or other payment satisfactory to the holders of the Senior Indebtedness before holders of the Securities shall be entitled to receive any payment with respect to the Securities; and

(b) until all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of the Senior Indebtedness, any distribution to which holders of the Securities would be entitled but for this Article IV shall be made to holders of Senior Indebtedness, as their interests may appear.

Section 4.3. Default on Designated Senior Indebtedness.

Anything in this Indenture to the contrary notwithstanding, no payment of Principal Amount, plus any accrued and unpaid interest (including any Additional Interest) on or other amounts due on the Securities, and no redemption, repurchase or other acquisition of the Securities, shall be made by or on behalf of the Company unless:

(a) full payment of all amounts then due for principal of and interest on, and of all other amounts then due on, all Designated Senior Indebtedness has been made or duly provided for pursuant to the terms of the instruments governing such Designated Senior Indebtedness; and

(b) at the time for, and immediately after giving effect to, any such payment, redemption, repurchase or other acquisition, there shall not exist under any Designated Senior Indebtedness, or any agreement pursuant to which any Designated Senior Indebtedness is issued, any default which shall not have been cured or waived and which default shall have resulted in the full amount of such Designated Senior Indebtedness being declared due and payable.

In addition, if a Responsible Officer of the Trustee at the Corporate Trust Office shall receive written notice from the holders of Designated Senior Indebtedness or their representative (a “Payment Blockage Notice”) that there has occurred and is continuing under such Designated Senior Indebtedness, or any agreement pursuant to which such Designated Senior Indebtedness is issued, any non-payment default, which default shall not have been cured or waived, giving the holders of such Designated Senior Indebtedness the right to declare such Designated Senior Indebtedness immediately due and payable, then, anything in this Indenture to the contrary notwithstanding, no payment of Principal Amount, plus any accrued and unpaid interest (including any Additional Interest) on, or any other amounts due on the Securities, and no redemption, repurchase or other acquisition of the Securities, shall be made by or on behalf of the Company during the period (the “Payment Blockage Period”) commencing on the date of receipt of the Payment Blockage Notice and ending on the earliest of (i) the date on which such default shall have been cured or waived, (ii) 179 days from the receipt of the Payment Blockage Notice and (iii) the date the Payment Blockage Notice is withdrawn by the holders of such

28

Designated Senior Indebtedness. Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in Section 4.2 and the first sentence of this Section 4.3), unless the holders of such Designated Senior Indebtedness or the representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, the Company may resume payments on the Securities after the end of such Payment Blockage Period. Not more than one Payment Blockage Notice may be given in any consecutive 365-day period, irrespective of the number of defaults with respect to one or more issues of Designated Senior Indebtedness during such period.

Section 4.4. Acceleration of Convertible Subordinated Notes.

In the event of the acceleration of the Securities because of an Event of Default, the Company may not make any payment or distribution to the Trustee or any holder of Securities in respect of Obligations with respect to the Securities and may not acquire or purchase from the Trustee or any holder of Securities any Securities until all Senior Indebtedness has been paid in full in cash or other payment satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of this Indenture.

If payment of the Securities is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness or trustees of such Senior Indebtedness of the acceleration.

Section 4.5. When Distribution Must Be Paid Over.

In the event that the Trustee, any holder of Securities or any other person receives any payment or distributions of assets of the Company of any kind with respect to the Securities in contravention of any subordination terms contained in this Indenture, whether in cash, property or securities, including, without limitation, by way of set-off or otherwise, then such payment shall be held by the recipient in trust for the benefit of holders of Senior Indebtedness, and shall be immediately paid over and delivered to the holders of Senior Indebtedness or their representative, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution or provision therefor, to or for the holders of Senior Indebtedness; provided, however, that the foregoing shall apply to the Trustee only if a Responsible Officer of the Trustee has actual knowledge (as determined in accordance with Section 4.11) that such payment or distribution is prohibited by this Indenture.

With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article IV, and no implied covenants or obligations with respect to the holders of Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to or on behalf of holders of Securities or the Company or any other person money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article IV.

Section 4.6. Subordination Notice by Company.

The Company shall promptly notify the Trustee in writing of any facts known to the Company that would cause a payment of any Obligations with respect to the Securities or the

29

purchase of any Securities by the Company to violate this Article IV, but failure to give such notice shall not affect the subordination of the Securities to the Senior Indebtedness as provided in this Article IV.

Notwithstanding the provisions of this or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until a Responsible Officer of the Trustee shall have received written notice at the Corporate Trust Office from the Company or a holder of Senior Indebtedness or from any trustee or agent therefor; and, prior to the receipt of any such written notice, the Trustee shall be entitled in all respects to assume that no such facts exist; provided, however, that if a Responsible Officer of the Trustee shall not have received, at least three Business Days prior to the date upon which by the terms hereof any such money may become payable for any purpose, the notice with respect to such money provided for in this Section 4.6, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date.

The Trustee shall be entitled to conclusively rely on the delivery to it of a written notice by a person representing himself to be a holder of Senior Indebtedness (or a trustee or agent on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee or agent on behalf of any such holder). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such person, the extent to which such person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such person under this Article, and if such evidence is not furnished, the Trustee may defer any payment which it may be required to make for the benefit of such person pursuant to the terms of this Indenture pending judicial determination as to the rights of such person to receive such payment.

Section 4.7. Subrogation.

After all Senior Indebtedness is paid in full and until the Securities are paid in full, holders of Securities shall be subrogated (equally and ratably with all other indebtedness pari passu with the Securities) to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness to the extent that distributions otherwise payable to the holders of Securities have been applied to the payment of Senior Indebtedness. A distribution made under this Article IV to holders of Senior Indebtedness that otherwise would have been made to holders of Securities is not, as between the Company and holders of Securities, a payment by the Company on the Securities.

30

Section 4.8. Relative Rights.

This Article IV defines the relative rights of holders of Securities and holders of Senior Indebtedness. Nothing in this Indenture shall:

(a) impair, as between the Company and holders of Securities, the obligation of the Company, which is absolute and unconditional, to pay the Principal Amount and interest (including any Additional Interest) on the Securities in accordance with their terms;

(b) affect the relative rights of holders of Securities and creditors (other than with respect to Senior Indebtedness) of the Company, other than their rights in relation to holders of Senior Indebtedness; or

(c) prevent the Trustee or any holder of Securities from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Indebtedness to receive distributions and payments otherwise payable to holders of Securities.

If the Company fails because of this Article IV to pay the Principal Amount, plus any accrued and unpaid interest (including any Additional Interest) on a Security on the due date, the failure is still a Default or Event of Default.

Section 4.9. Subordination May Not Be Impaired by Company.

No right of any holder of Senior Indebtedness to enforce the subordination of the indebtedness evidenced by the Securities shall be impaired by any act or failure to act by the Company or any holder of Securities or by the failure of the Company or any such holder to comply with this Indenture.

Section 4.10. Distribution or Notice to Representative.

Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their representative.

Upon any payment or distribution of assets of the Company referred to in this Article IV, the Trustee and the holders of Securities shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such representative or of the liquidating trustee or agent or other person making any distribution to the Trustee or to the holders of Securities for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article IV.

Section 4.11. Rights of Trustee and Paying Agent.

Notwithstanding the provisions of this Article IV or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee may continue to make payments on the Securities, unless a Responsible Officer of the Trustee shall have received at the Corporate Trust Office at least five Business Days prior to the date of such payment or distribution written notice of facts that would cause such payment or distribution with respect to the Securities to violate this Article IV. Only the Company may give such notice.

31

Nothing in this Article IV shall impair the claims of, or payments to, the Trustee under or pursuant to Section 8.1 and Section 9.7 hereof, and the Trustee’s rights to compensation, reimbursement and indemnification under Section 8.10 and Section 9.07 are not subordinated.

The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee.

Section 4.12. Authorization to Effect Subordination.

Each holder of a Security by the holder’s acceptance thereof authorizes and directs the Trustee on the holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article IV, and appoints the Trustee to act as the holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 8.9 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Indebtedness or their representatives are hereby authorized to file an appropriate claim for and on behalf of the holders of the Securities.

Section 4.13. Article Applicable to Paying Agents.

In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article IV shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article IV in addition to or in place of the Trustee; provided, however, that the second and third paragraphs of Section 4.11 shall not apply to the Company or any Subsidiary of the Company if it or such Subsidiary acts as Paying Agent.

Section 4.14. Senior Indebtedness Entitled to Rely.

The holders of Senior Indebtedness shall have the right to rely upon this Article IV, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless the holders affected thereby shall have agreed in writing thereto.

Section 4.15. Permitted Payments.

Notwithstanding anything to the contrary in this Article IV, the holders of Securities may receive and retain at any time on or prior to Stated Maturity (i) securities that are subordinated to at least the same extent as the Securities to (a) Senior Indebtedness and (b) any securities issued in exchange for Senior Indebtedness and (ii) payments and other distributions made from any trust created pursuant to Section 10.1.

ARTICLE V

Section 5.1. Fundamental Change Put.

(a) In the event that a Fundamental Change shall occur at any time prior to February 15, 2011, each Holder shall have the right, at the Holder’s option, but subject to the provisions of this Section 5.1, to require the Company to purchase, and upon the

32

exercise of such right, the Company shall purchase, all of such Holder’s Securities not theretofore called for redemption, or any portion of the Principal Amount thereof that is equal to $1,000 or an integral multiple thereof, as directed by such Holder pursuant to this Section 5.1, on the date designated by the Company (the “Fundamental Change Purchase Date”) that is a Business Day no later than 35 Business Days after the date of notice pursuant to Section 5.1(b) of the occurrence of a Fundamental Change (subject to extension to comply with applicable law). The Company shall be required to purchase such Securities at a purchase price in cash or subject to fulfillment by the Company of the conditions set forth in this Section 5, shares of Applicable Stock (valued at 95% of the market price of such stock), in an amount or value equal to 100% of the Principal Amount plus any accrued and unpaid interest (including any Additional Interest) to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”). In the event that a Fundamental Change Purchase Date is a date that is after any Regular Record Date but on or before the corresponding Interest Payment Date, the Company shall be required to pay accrued and unpaid interest and Additional Interest, if any, to the holder of the repurchased Security and not the Holder on the Regular Record Date.

Subject to the fulfillment by the Company of the conditions set forth in this Section 5, the Company may elect to pay the Fundamental Change Purchase Price by delivering a number of shares of Common Stock equal to (i) the Fundamental Change Purchase Price divided by (ii) 95% of the average of the closing sales prices per share of Common Stock for the five consecutive Trading Days immediately preceding the second Trading Day prior to the Fundamental Change Purchase Date.

(b) No later than 20 calendar days after the occurrence of a Fundamental Change, the Company shall mail a written notice of the Fundamental Change by first class mail to the Trustee (and the Paying Agent if the Trustee is not then acting as Paying Agent) and to each Holder at its address shown in the Register of the Registrar, and to beneficial owners as required by applicable law. The notice shall include a form of Fundamental Change Purchase Notice to be completed by the Holder and shall briefly state, as applicable:

(i)        the date of such Fundamental Change and, briefly, the events causing such Fundamental Change;

(ii)       the date by which the Fundamental Change Purchase Notice must be delivered to the Paying Agent in order for a Holder to exercise the purchase right pursuant to this Section 5.1;

(iii)      the Fundamental Change Purchase Date;

(iv)     the Fundamental Change Purchase Price and whether the Fundamental Change Purchase Price will be paid in cash or Applicable Stock;

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

33

(vi)     the Conversion Rate and any adjustments thereto;

(vii)    that the Securities as to which a Fundamental Change Purchase Notice has been given may be converted into Common Stock pursuant to Article XII of this Indenture only if the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this Indenture;

(viii)   that the Securities must be surrendered to the Paying Agent to collect payment;

(ix)      that the Fundamental Change Purchase Price for any Security as to which a Fundamental Change Purchase Notice has been duly given and not withdrawn shall be paid promptly following the later of the Fundamental Change Purchase Date and the time of surrender of such Security as described in Section 5.1(b)(viii)

(x)       the procedures the Holder must follow to exercise rights under this Section 5.1 and a brief description of such rights;

(xi)      briefly, the conversion rights of the Securities, and that the Holder must satisfy the requirements set forth in the Indenture in order to convert the Securities;

(xii)     the procedures for withdrawing a Fundamental Change Purchase Notice, including a form of notice of withdrawal;

(xiii)    that, unless the Company defaults in making payment of such Fundamental Change Purchase Price, interest (including any Additional Interest), if any, on Securities surrendered for purchase by the Company shall cease to accrue on and after the Fundamental Change Purchase Date; and

(xiv)    the CUSIP number(s) of the Securities.

Upon receipt of a Company Request, the Trustee shall give the notice of purchase right in the Company’s name and at the Company’s expense; provided, however, that the Company makes such request at least five Business Days (unless a shorter period shall be satisfactory to the Trustee) prior to the date by which such notice of purchase right must be given to the Holders in accordance with this Section 5.1(b); provided, further, that the text of the notice of purchase right shall be prepared by the Company.

If any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to the purchase of Global Securities.

34

Simultaneously with delivering the written notice pursuant to this Section 5.1(b), the Company shall publish a notice containing all information specified in such written notice in a newspaper of general circulation in New York, New York or publish such information on the Company’s website, or through such other public medium that reasonably could be expected to inform Holders of such information.

(c) A Holder may exercise its rights specified in clause (a) of this Section 5.1 upon delivery of a written notice (which shall be in substantially the form included on the reverse side of the Securities entitled “Option of Holder to Elect Purchase” and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s customary procedures) of the exercise of such rights (a “Fundamental Change Purchase Notice”) to the Paying Agent at any time on or before the 20th Business Day after the date of the Company’s notice of the Fundamental Change (subject to extension to comply with applicable law).

The Fundamental Change Purchase Notice delivered by a Holder shall state (i) the Fundamental Change Purchase Date, (ii) if certificated Securities, the certificate number or numbers of the Security or Securities which the Holder shall deliver to be purchased (if not certificated, the notice must comply with Applicable Procedures), (iii) the portion of the Principal Amount of the Security which the Holder shall deliver to be purchased, which portion must be $1,000 or an integral multiple thereof, and (iv) that such Security shall be purchased pursuant to the terms and conditions specified in the Securities and this Indenture.

Delivery of a Security (together with all necessary endorsements) to the Paying Agent by book-entry transfer or physical delivery prior to, on or after the Fundamental Change Purchase Date at the offices of the Paying Agent is a condition to receipt by the Holder of the Fundamental Change Purchase Price therefor; provided, however, that such Fundamental Change Purchase Price shall be so paid pursuant to this Section 5.1 only if the Security so delivered to the Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Purchase Notice, as determined by the Company.

The Company shall purchase from the Holder thereof, pursuant to this Section 5.1, a portion of a Security if the Principal Amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of the Indenture that apply to the purchase of all of a Security pursuant to Section 5.1 through Section 5.6 also apply to the purchase of such portion of such Security.

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

Anything herein to the contrary notwithstanding, in the case of Global Securities, any Fundamental Change Purchase Notice may be delivered or withdrawn and such Securities may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in effect from time to time.

35

Such Fundamental Change Purchase Price shall be paid to such Holder, subject to receipt of cash or if the conditions for payment in Applicable Stock set forth in Section 5 are fulfilled, Common Stock by the Paying Agent, promptly following the later of (a) the Fundamental Change Purchase Date with respect to such Security (provided the conditions in Section 5.1(c) have been satisfied) and (b) the time of book-entry transfer or delivery of such Security to the Paying Agent by the Holder thereof in the manner required by Section 5.1(c).

Section 5.4. Deposit of Fundamental Change Purchase Price.

Prior to 10:00 a.m., New York City time, on the applicable Fundamental Change Purchase Date, the Company shall deposit 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 2.4) an amount of cash (in immediately available funds if deposited on such Business Day) or, if the conditions for payment in Applicable Stock set forth in this Section 5 are fulfilled, Common Stock with a value sufficient to pay the aggregate Fundamental Change Purchase Price of all the Securities or portions thereof which are to be purchased as of such Fundamental Change Purchase Date.

The Company shall publicly announce the Principal Amount of Securities purchased as a result of such Fundamental Change on or as soon as practicable after the Fundamental Change Purchase Date by publishing a notice containing such information in a newspaper of general circulation in New York, New York or by publishing such information on the Company’s website, or through such other public medium that reasonably could be expected to inform Holders of such information.

Notwithstanding the foregoing, so long as the Securities are registered in the name of a Depositary or its nominee, all payments with respect to the Securities shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

Section 6.2. SEC and Other Reports to the Trustee.

(a) The Company shall ensure delivery to the Trustee within 15 calendar days after it files such annual and quarterly reports, information, documents and other reports with the SEC, copies of its annual report and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act in accordance with TIA Section 314(a). In the event the Company is at any time no longer subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it shall continue to provide the Trustee with reports containing substantially the same information as would have been required to be filed with the SEC had the Company continued to have been subject to such reporting requirements. In such event, such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to such reporting requirements. The Company also shall comply with the other provisions of TIA Section 314(a). Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely conclusively on

39

Officers’ Certificates). The Trustee shall have no duty or responsibility to review such reports, information or documents.

(b) The Company intends to file the reports referred to in paragraph (a) above in this Section 6.2 hereof with the SEC in electronic form pursuant to Regulation S-T of the SEC using the SEC’s Electronic Data Gathering, Analysis and Retrieval (“EDGAR”) system. Within 15 days after the Company files with the SEC copies of its annual reports and other information, documents and reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which it is required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, the Company shall file the same with the Trustee. The Company also shall comply with the other provisions of TIA 314(a). The Company may deliver such reports to the Trustee by electronic means in replace of mailing such reports, provided, however, the Trustee agrees to such other means in writing. The Trustee shall have no duty to search for or obtain any electronic or other filings that the Company makes with the SEC, regardless of whether such filings are periodic, supplemental or otherwise. Delivery of the reports, information and documents to the Trustee pursuant to this Section 6.2(b) shall be solely for the purposes of compliance with this Section 6.2(b) and with TIA Section 314(a). The Trustee’s receipt of such reports, information and documents shall not constitute notice to it of the contents thereof or of any matter determinable from the content thereof, including the Company’s compliance with any of its covenants hereunder, as to which the Trustee is entitled to rely upon Officers’ Certificates.

Section 6.3. Compliance Certificate.

The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Company an Officers’ Certificate, stating whether or not to the knowledge of the signers thereof, the Company is in compliance with all conditions and covenants under this Indenture.

Section 6.4. Further Instruments and Acts.

The Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

Section 6.5. Maintenance of Office or Agency of the Trustee, Registrar, Paying Agent and Conversion Agent.

The Company shall maintain in the Borough of Manhattan, New York, New York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer, exchange, redemption, repurchase or conversion and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The office of the Trustee located in New York City at Corporate Trust Office, shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). If at any time the

40

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 14.2.

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, New York, New York, for such purposes.

Section 6.6. Delivery of Information Required Under Rule 144A.

Upon the request of a Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock issued upon conversion thereof, the Company shall promptly furnish or cause to be furnished the information required pursuant to Rule 144A(d)(4) under the Securities Act to such Holder or any beneficial owner of Securities or holder or beneficial owner of Common Stock, or to a prospective purchaser of any such security designated by any such holder, as the case may be, to the extent required to permit compliance by such Holder or holder with Rule 144A under the Securities Act in connection with the resale of any such security. Whether a person is a beneficial owner shall be determined by the Company to the Company’s reasonable satisfaction.

Section 6.7. Waiver of Stay, Extension or Usury Laws.

The Company covenants (to the extent that it may lawfully do so) that it shall 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, Redemption Price, Purchase Price or Fundamental Change Purchase Price in respect of Securities, or any interest and Additional Interest, if any, on such amounts, 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 law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

Section 6.8. Statement by Officers as to Default.

The Company shall deliver to the Trustee, as soon as practicable and in any event within five Business Days after the Company becomes aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default and the action which the Company proposes to take with respect thereto.

(a) either (i) the Company shall be the continuing corporation or (ii) 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, sale, lease or other disposition all or substantially all of the properties and assets of the Company substantially as an entirety (1) shall be organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (2) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all of the obligations of the Company under the Securities, this Indenture and the Registration Rights Agreement and, to the extent applicable, otherwise comply with the provisions of Section 12.4;

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise) of the properties and assets of one or more Subsidiaries, which, if such assets were owned by the Company, together with the assets of all of the other Subsidiaries of the Company, would constitute all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company unless such transfer is to the Company or another Subsidiary. The successor Person formed by such consolidation or into which the Company is merged or the successor Person to which such conveyance, transfer, sale, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein; and thereafter, except in the case of a conveyance, transfer, sale, lease or other disposition and any obligations the Company may have under a supplemental indenture, the Company shall be discharged from all obligations and covenants under this Indenture and the Securities. Subject to Section 11.6, the Company, the Trustee and the successor Person shall enter into a supplemental indenture to evidence the succession and substitution of such successor Person and such discharge and release of the Company.

(h) there shall have occurred a default under any credit agreement, mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness of the Company or any of its Subsidiaries for money borrowed whether such Indebtedness now exists, or is created after the date of this Indenture, which default (i) involves the failure to pay principal of or any premium or interest on such Indebtedness in an amount in excess of $7.5 million when such Indebtedness becomes due and payable at the stated maturity thereof, and such default shall continue after any applicable grace period or (ii) results in the acceleration of such Indebtedness prior to the stated maturity thereof, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness so unpaid at its stated maturity or the stated maturity of which has been so accelerated, aggregates $10,000,000 or more;

43

(iii)      orders the winding up or liquidation of the Company or any Designated Subsidiary, and the order of decree remains unstayed and in effect for 60 days.

Section 8.2. Acceleration.

If an Event of Default (other than an Event of Default specified in Section 8.1(j) or Section 8.1(k) with respect to the Company) occurs and is continuing (including an Event of Default specified in Section 8.1(j) or Section 8.1(k) with respect to one or more Designated Subsidiaries), 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

44

Trustee, may declare the principal amount plus accrued and unpaid interest and Additional Interest, if any, on all the Securities to be immediately due and payable.

Upon such a declaration, such accelerated amount shall be due and payable immediately.

If an Event of Default specified in Section 8.1(j) or Section 8.1(k) occurs with respect to the Company and is continuing, the principal amount plus accrued and unpaid interest and Additional Interest, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

The Holders of not less than a majority in aggregate principal amount of the Securities at the time outstanding, by notice to the Trustee (and without notice to any other Holder) may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if all existing Events of Default have been cured or waived except nonpayment of the Principal Amount plus accrued and unpaid interest and Additional Interest, if any, that have become due solely as a result of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

Section 8.3. Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy to collect the payment of the Principal Amount plus accrued and unpaid interest and Additional Interest, if any, on the Securities 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 Holder 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 8.4. Waiver of Existing Defaults.

Subject to Section 8.7 and Section 11.2, 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 Holder), may waive certain provisions of this Indenture relating to the Securities, except for: (a) an Event of Default described in Section 8.1(a), Section 8.1(b), or Section 8.1(c); or (b) a Default in respect of any provision of this Indenture or the Securities, which, under Section 11.2, cannot be amended or modified without the consent of each Holder affected thereby.

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. This Section 8.4 shall be in lieu of Section 316(a)1(B) of the TIA and such Section 316(a)1(B) is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 8.5. 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,

45

the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines in good faith is prejudicial to the rights of other Holders or would involve the Trustee in personal liability or expense unless the Trustee is provided security or indemnity satisfactory to it. This Section 8.5 shall be in lieu of Section 316(a)1(A) of the TIA and such Section 316(a)1(A) is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 8.6. Limitation on Suits.

A Holder 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 provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt of such notice, request and 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 Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder.

Section 8.7. Rights of Holders to Receive Payment or to Convert.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of the Principal Amount, Redemption Price, Purchase Price, Fundamental Change Purchase Price or interest and Additional Interest, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities and in this Indenture, and to convert such Securities in accordance with Article XII, or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected adversely without the consent of such Holder.

Section 8.8. Collection Suit by Trustee.

If an Event of Default described in Section 8.1(a), Section 8.1(b), Section 8.1(d) or Section 8.1(e) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount owing with respect to the Securities and the amounts provided for in Section 9.7.

46

Section 8.9. 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, Redemption Price, Purchase Price, Fundamental Change Purchase Price or interest and Additional Interest, if any, 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, Redemption Price, Purchase Price, Fundamental Change Purchase Price, or interest and Additional Interest, if any, 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 or any other amounts due the Trustee under Section 9.7) 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 9.7.

Nothing contained herein 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 claim of any Holder in any such proceeding.

Section 8.10. Priorities.

After an Event of Default any money or other property distributable in respect of the Company’s obligations under this Indenture shall be paid in the following order:

FIRST: to the Trustee (including any predecessor trustee) for amounts due under Section 9.7;

SECOND: to Holders for amounts due and unpaid on the Securities for the Principal Amount, Redemption Price, Purchase Price, Fundamental Change Purchase Price or interest and Additional Interest, if any, 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.

47

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 8.10. At least 10 calendar days prior to such record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and the amount to be paid.

Section 8.11. 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 and expenses, 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 8.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 8.7 or a suit by Holders of more than 10% in aggregate principal amount of the Securities at the time outstanding. This Section 8.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA.

Section 9.7. Compensation and Indemnity.

The Company agrees to:

(a) pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing for all services rendered by it hereunder (which compensation shall not be limited (to the extent permitted by law) by any provision of law in regard to the compensation of a trustee of an express trust);

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

(c) fully indemnify the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any and all loss, damage, claim, liability, cost or expense (including attorney’s fees and expenses, and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)) incurred without the Trustee’s negligent action, negligent failure to act or willful misconduct, 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 (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section 9.7.

With regard to its indemnification rights under Section 9.7(c) where the Company has assumed the defense in any action or proceeding, the Trustee shall have the right to employ separate counsel in any such action or proceeding and participate in the investigation and defense thereof, and the Company shall pay the reasonable fees and expenses of such separate counsel; provided, however, that the Trustee may only employ separate counsel at the expense of the Company if in the reasonable determination of the Trustee (i) a conflict of interest exists by reason of common representation or (ii) there are legal defenses available to the Trustee that are

52

different from or are in addition to those available to the Company or (iii) if all parties commonly represented do not agree as to the action (or inaction) of counsel.

To secure the Company’s payment obligations in this Section 9.7, 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, Redemption Price, Purchase Price, Fundamental Change Purchase Price or interest and Additional Interest, if any, as the case may be, on particular Securities.

The Company’s payment obligations pursuant to this Section 9.7 and the lien referred to in this Section 9.7 shall survive the discharge of this Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 8.1(j) or Section 8.1(k), the expenses including the reasonable charges and expenses of its counsel, are intended to constitute expenses of administration under any Bankruptcy Law.

Section 9.8. Replacement of Trustee.

The Trustee may resign by so notifying the Company; provided, however, that no such resignation shall be effective until a successor Trustee has accepted its appointment pursuant to this Section 9.8. 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 the Company. The Company shall remove the Trustee if:

(a) the Trustee fails to comply with Section 9.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(c) a receiver or public officer takes charge of the Trustee or its property; or

(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 satisfactory in form and substance to the retiring Trustee and 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 Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, upon payment of all the retiring Trustee’s fees and expenses then due and payable and subject to the lien provided for in Section 9.7.

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 at the expense of the Company any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

53

If the Trustee fails to comply with Section 9.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Section 9.9. Successor Trustee by Merger.

If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

Section 9.10. Eligibility; Disqualification.

The Trustee and any successor Trustee shall at all times satisfy the requirements of TIA Sections 310(a)(1) and 310(b). The Trustee (or its parent 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 condition. Nothing contained herein shall prevent the Trustee from filing with the Commission the application referred to in the penultimate paragraph of TIA Section 310(b). If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.10, it shall resign immediately in the manner and with the effect specified above in this Article.

Section 9.11. Preferential Collection of Claims Against Company.

The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

ARTICLE X

DISCHARGE OF INDENTURE

Section 10.1. Discharge of Liability on Securities.

When (i) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced or repaid pursuant to Section 2.7) for cancellation or (ii) all outstanding Securities have become due and payable (whether at the Stated Maturity or upon acceleration, or on any Redemption Date, Purchase Date or Fundamental Change Purchase Date, or upon conversion) and the Company deposits with the Paying Agent or Conversion Agent cash or Applicable Stock sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.7), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 9.7, cease to be of further effect subject to any extension required by Section 12. to effect settlement upon conversion of the Notes.

After return to the Company, Holders entitled to the cash or securities must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person and the Trustee and the Paying Agent shall have no further liability to the Holders with respect to such cash or securities for that period commencing after the return thereof.

ARTICLE XI

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 of revocation before the date the amendment, waiver or action becomes effective.

ARTICLE XII

CONVERSION

Section 12.1. Conversion Right.

(a) Subject to and upon compliance with the provisions of this Article XII, a Holder of a Security shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 or an integral multiple of $1,000) of the Principal Amount of such Security into a number of shares of Common Stock equal to the product of (x) the Conversion Rate in effect on the date of conversion times (y) the quotient of the Principal Amount at Issuance of the Security or portion thereof surrendered for conversion divided by 1,000:

With respect to any conversion of a Security during a Registration Default Period following satisfaction of any of the conditions to conversion described in this Indenture (and during the prescribed time periods in respect thereof), a Holder shall be entitled to, 103% of the number

58

of shares of Common Stock that the Holder would have otherwise been entitled to upon conversion.

(b) (i)    In the event that:

(A)           the Company distributes to all holders of its Common Stock rights or warrants entitling them (for a period expiring within 60 days of the Record Date for such distribution) to subscribe for or purchase Common Stock at a price per share of Common Stock less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the announcement of such distribution;

(B)             the Company distributes to all holders of its Common Stock cash or other assets, debt securities or rights or warrants to purchase its securities, including the declaration of any cash dividends, payable quarterly or otherwise, where the Fair Market Value (as determined by the Board of Directors) of such distribution per share of Common Stock exceeds 10% of the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of declaration of such distribution; or

(C)             a Fundamental Change occurs,

then, in each case, the Securities may be surrendered for conversion at any time on and after the date that the Company gives notice to the Holders of such right, which shall be, in the case of (A) or (B), not less than 15 Business Days prior to the Ex-Dividend Time for such distribution, or, in the case of (C), within 15 Business Days after the occurrence of the Fundamental Change, until 5:00 p.m., New York City time, on the earlier of the Business Day immediately preceding the Ex-Dividend Time and the date the Company announces that such distribution shall not take place in the case of (A) or (B), or within 20 Business Days of the Company’s delivery of the notice of the Fundamental Change in the case of (C); provided, however, that in the case of (A) or (B), a Holder of Securities may not surrender Securities for conversion if the Holder shall otherwise participate in such distribution without conversion.

(ii)          In addition, in the event that the Company consolidates with or merges into another corporation, or is a party to a binding share exchange pursuant to which the Common Stock would be converted into cash, securities or other property as set forth in Section 12.4, then the Securities may be surrendered for conversion at any time from and after the date which is 15 calendar days prior to the date announced by the Company as the anticipated effective

59

time of such transaction until 15 calendar days after the actual date of such transaction.

(c) Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice, as the case may be, exercising such Holder’s right to require the Company to repurchase such Security may be converted only if such Fundamental Change Purchase Notice is withdrawn in accordance with Section 4.2(b) or Section 5.2(b) prior to 5:00 p.m., New York City time, on the Business Day immediately preceding such Purchase Date or Fundamental Change Purchase Date.

Section 12.2. Conversion Procedures; Conversion Rate; Fractional Shares.

(a) Each Security shall be convertible at the office of the Conversion Agent into fully paid and nonassessable shares of Common Stock (calculated to the nearest 1/10,000th of a share).

(b) The Conversion Agent shall notify the Company when it receives a Conversion Notice. The Company shall determine the number of shares of Common Stock and/or the amount of cash, if any, that the Holder that submitted the Conversion Notice is entitled to receive upon surrender of the Securities covered by that Conversion Notice. A certificate for the number of full shares of Common Stock into which the Securities are converted (and cash in lieu of fractional shares) shall be delivered to such Holder, assuming all of the other requirements have been satisfied by such Holder, as soon as practicable. Notwithstanding the foregoing, the Company shall not be required to deliver certificates for Common Stock while the stock transfer books for such stock or the security register are duly closed for any purpose, but certificates for Common Stock shall be issued and delivered as soon as practicable after the opening of such books or security register. No cash payment of accrued and unpaid interest or Additional Interest shall be paid by the Company on a converted Security, except as described in Section 12.9. Accrued and unpaid interest and Additional Interest, if any, shall be deemed to be paid in full with the shares of Common Stock issued or cash paid upon conversion, rather than deemed cancelled, extinguished or forfeited.

Except as described in Section 12.9, the Company will not make any payment in cash or Common Stock or other adjustment for accrued and unpaid interest or Additional Interest on any Securities when they are converted. The Company’s delivery to the Holder of the full number of shares of Common Stock into which the Security is convertible, together with any cash payment for such Holder’s fractional shares, shall be deemed to satisfy the Company’s obligation to pay the Principal Amount of the Security and to satisfy its obligation to pay accrued and unpaid interest and Additional Interest, if any through the conversion date. As a result, accrued interest, and Additional Interest are deemed paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, accrued interest and Additional Interest, if any, will be payable upon any conversion of Securities made concurrently with or after acceleration of the Securities following an Event of Default.

If a Holder has submitted any or all of its Securities for repurchase, a Holder’s conversion rights on the Securities so subject to repurchase shall expire at 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Purchase Date. Notwithstanding the foregoing, a Security in respect of which a Holder has delivered a

60

Fundamental Change Purchase Notice exercising such Holder’s right to require the Company to repurchase such Security may be converted only if such Fundamental Change Purchase Notice is withdrawn in accordance with Section 4.2(b) prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Fundamental Change Purchase Date.

(c) Before any Holder shall be entitled to convert the same into Common Stock, such Holder shall, in the case of Global Securities, comply with the Applicable Procedures of the Depositary in effect at that time, and in the case of Certificated Securities, surrender such Securities, duly endorsed to the Company or in blank, at the office of the Conversion Agent, and shall give written notice to the Company at said office or place in the form of the Conversion Notice attached to the Security (the “Conversion Notice”) that such Holder elects to convert the same and shall state in writing therein the Principal Amount at issuance of Securities to be converted (in whole or in part so long as the Principal Amount to be converted is in multiples of $1,000) and the name or names (with addresses) in which such Holder wishes the certificate or certificates for Common Stock to be issued.

Before any such conversion, a Holder also shall pay all funds required, if any, relating to interest or Additional Interest, if any, on the Securities, as provided in Section 12.9 and all taxes or duties, if any, as provided in Section 12.8.

If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock that shall be deliverable upon conversion shall be computed on the basis of the aggregate Principal Amount at issuance of the Securities (or specified portions thereof to the extent permitted thereby) so surrendered.

If shares of Common Stock to be issued upon conversion of a Restricted Security is to be issued in the name of a Person other than the Holder of such Restricted Security, such Holder shall deliver to the Conversion Agent a certification in substantially the form set forth in a Transfer Certificate dated the date of surrender of such Restricted Security and signed by such Holder, as to compliance with the restrictions on transfer applicable to such Restricted Security. The Company shall not be required to issue Common Stock upon conversion of any such Restricted Security to a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification, and the Registrar shall not be required to register Common Stock upon conversion of any such Restricted Security in the name of a Person other than the Holder if such Restricted Security is not so accompanied by a properly completed certification.

(d) A Security shall be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the date on which all of the conversion requirements set forth in Section 12.2(b) have been satisfied, and the person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record Holder or Holders of such Common Stock as of 5:00 p.m., New York City time, on such date.

(e) In case any Certificated Security shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Security so surrendered, without charge to such Holder (subject to the provisions of Section 12.8), a new Security or Securities in authorized

61

denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Certificated Securities.

Section 12.3. Adjustment of Conversion Rate.

The Conversion Rate shall be adjusted from time to time as follows:

(a) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, pay a dividend or make a distribution in Common Stock to all or substantially all holders of its outstanding Common Stock, then the Conversion Rate in effect immediately prior to the close of business on the Record Date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have received had such Security been converted immediately prior to the happening of such event as well as such additional shares it would have received as a result of such event. Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date fixed for such determination. If any dividend or distribution of the type described in this Section 12.3(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(b) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, subdivide its outstanding shares of Common Stock into a greater number of Common Stock or combine its outstanding shares of Common Stock into a smaller number of Common Stock, then the Conversion Rate in effect immediately prior to the close of business on the day upon which such subdivision or combination becomes effective shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have received had such Security been converted immediately prior to the happening of such event as well as such additional shares as it would have received as a result of such event. Such adjustment shall become effective immediately prior to the opening of business on the day following the day upon which such subdivision or combination becomes effective.

(c) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, issue rights or warrants for a period expiring within 60 days (other than any rights or warrants referred to in Section 12.3(d)) to all or substantially all holders of its outstanding Common Stock entitling them to subscribe for or purchase Common Stock (or securities convertible into or exchangeable or exercisable for Common Stock), at a price per share of Common Stock (or having a conversion, exchange or exercise price per share of Common Stock) less than the Closing Sale Price of the Common Stock on the Business Day immediately preceding the date of announcement of such issuance (treating the conversion, exchange or exercise price per share of Common Stock of the securities convertible, exchangeable or exercisable into Common Stock as equal to (x) the sum of (i) the price for a unit of the security convertible into or exchangeable or exercisable for Common Stock and (ii) any additional consideration initially payable upon the conversion of or exchange or exercise for such security into Common Stock divided by (y) the number of shares of Common Stock initially underlying such convertible, exchangeable or exercisable

62

security), then the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect at the opening of business on the date after such date of announcement by a fraction:

(i)             the numerator of which shall be the number of shares of Common Stock outstanding at the close of business on the date of announcement, plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible, exchangeable or exercisable securities so offered are convertible, exchangeable or exercisable); and

(ii)          the denominator of which shall be the number of shares of Common Stock outstanding on the close of business on the date of announcement, plus the number of shares of Common Stock (or convertible, exchangeable or exercisable securities) which the aggregate offering price of the total number of shares of Common Stock (or convertible, exchangeable or exercisable securities) so offered for subscription or purchase (or the aggregate conversion, exchange or exercise price of the convertible, exchangeable or exercisable securities so offered) would purchase at such Closing Sale Price of the Common Stock.

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such determination. To the extent that shares of Common Stock (or securities convertible, exchangeable or exercisable into shares of Common Stock) are not delivered pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock (or securities convertible, exchangeable or exercisable into shares of Common Stock) actually delivered. In the event that such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Closing Sale Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, the value of such consideration if other than cash, to be determined by the Board of Directors.

(d) (A) In case the Company shall, at any time or from time to time while any of the Securities are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its outstanding shares of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation and the shares of Common Stock are not changed or exchanged), shares of its capital stock, evidences of its Indebtedness or other assets, including securities, but excluding (i) dividends or distributions of Common Stock referred to in Section 12.3(a),

63

(ii) any rights or warrants referred to in Section 12.3(c), (iii) dividends and distributions paid exclusively in cash referred to in this Section 12.3(d) and (iv) dividends and distributions of stock, securities or other property or assets (including cash) in connection with the reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies (such capital stock, evidence of its indebtedness, other assets or securities being distributed hereinafter in this Section 12.3(d) called the “Distributed Assets”), then, in each such case, subject to paragraphs (D) and (E) of this Section 12.3(d), the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction:

(i)    the numerator of which shall be the Current Market Price; and

(ii)   the denominator of which shall be such Current Market Price of the Common Stock, less the Fair Market Value on such date of the portion of the distributed assets so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the Record Date) on such date.

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared.

(B)   If the Board of Directors determines the Fair Market Value of any distribution for purposes of this Section 12.3(d) by reference to the actual or when issued trading market for any distributed assets comprising all or part of such distribution, it must in doing so consider the prices in such market over the same period (the “Reference Period”) used in computing the Current Market Price pursuant to Section 12.3(g) to the extent possible, unless the Board of Directors determines in good faith that determining the Fair Market Value during the Reference Period would not be in the best interest of the Holders.

(C)   In the event any such distribution consists of shares of capital stock of, or similar equity interests in, one or more of the Company’s Subsidiaries (a “Spin-Off”), the Fair Market Value of the securities to be distributed shall equal the average of the Closing Sale Prices of such securities on the principal securities market on which such securities are traded for the five consecutive Trading Days commencing on and including the sixth Trading Day of those securities after the effectiveness of the Spin-Off, and the Current Market Price shall be measured for the same period. In the event, however, that an underwritten initial public offering of the securities in the Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed in the Spin-Off shall mean the initial public offering price of such securities and the Current Market Price shall mean the Closing Sale Price for the Common Stock on the same Trading Day.

(D)  Rights or warrants distributed by the Company to all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Equity Interest (either initially or under certain circumstances), which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”), (x) are deemed to be transferred with such shares of Common Stock, (y) are not exercisable and (z) are also issued in respect of future issuances of Common Stock shall be deemed not to have been distributed for purposes of this Section 12.3(d) (and no adjustment to the Conversion Rate under this Section 12.3(d) shall be required) until the occurrence of the earliest Trigger Event. If such right or warrant is subject to subsequent events, upon the occurrence of which such right or warrant shall become exercisable to purchase different distributed assets, evidences of indebtedness or other assets, or entitle the holder to purchase a different number or amount of the foregoing or to purchase any of the foregoing at a different purchase price, then the occurrence of each such event shall be deemed to be the date of issuance and Record Date with respect to a new right or warrant (and a termination or expiration of the existing right or warrant without exercise by the holder thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto, that resulted in an adjustment to the Conversion Rate under this Section 12.3(d):

(i)    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 Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder of shares 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 purchase; and

(ii)   in the case of such rights or warrants which shall have expired or been terminated without exercise, the Conversion Rate shall be readjusted as if such rights and warrants had never been issued.

(E)   For purposes of this Section 12.3(d) and Section 12.3(a), Section 12.3(b) and Section 12.3(c), any dividend or distribution to which this Section 12.3(d) is applicable that also includes (x) shares of Common Stock, (y) a subdivision or combination of Common Stock to which Section 12.3(b) applies or (z) rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.3(c) applies (or any combination thereof), shall be deemed instead to be:

(i)    a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants, other than such shares of Common

Stock, such subdivision or combination or such rights or warrants to which Section 12.3(a), Section 12.3(b) and Section 12.3(c) apply, respectively (and any Conversion Rate adjustment required by this Section 12.3(d) with respect to such dividend or distribution shall then be made), immediately followed by

(ii)   a dividend or distribution of such shares of Common Stock, such subdivision or combination or such rights or warrants (and any further Conversion Rate adjustment required by Section 12.3(a), Section 12.3(b) and Section 12.3(c) with respect to such dividend or distribution shall then be made), except:

(1)    the Record Date of such dividend or distribution shall be substituted as (i) “the date fixed for the determination of stockholders entitled to receive such dividend or other distribution,” “Record Date fixed for such determinations” and “Record Date” within the meaning of Section 12.3(a), (ii) “the day upon which such subdivision or combination becomes effective” within the meaning of Section 12.3(b), and (iii) as “the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants” and such “Record Date” within the meaning of Section 12.3(c); and

(2)    any reduction or increase in the number of shares of Common Stock resulting from such subdivision or combination shall be disregarded in connection with such dividend or distribution.

(e) In case the Company shall, at any time or from time to time after the initial Issue Date while any of the Securities are outstanding, by dividend or otherwise, distribute to all or substantially all holders of its outstanding shares of Common Stock, cash (including any quarterly cash dividends, but excluding any cash that is distributed upon a reclassification, change, merger, consolidation, statutory share exchange, combination, sale or conveyance to which Section 12.4 applies or as part of a distribution referred to in Section 12.3(d)), then, and in each case, immediately after the close of business on such date, the Conversion Rate shall be adjusted by multiplying the Conversion Rate in effect immediately prior to the close of business of such Record Date by a fraction:

(A)  the numerator of which shall be equal to the Current Market Price on such date; and

(B)   the denominator of which shall be equal to the Current Market Price on the Record Date, less an amount equal to the quotient of (x) the aggregate amount of such cash distribution and (y) the number of shares of Common Stock outstanding on the Record Date.

66

Such adjustment shall become effective immediately prior to the opening of business on the day following the Record Date for such distribution. In the event that such distribution is not so made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such distribution had not been declared.

Notwithstanding the foregoing, adjustments to the conversion rate resulting from any quarterly cash dividends may not cause the conversion rate (as adjusted for any other adjustment) to exceed the quotient obtained by dividing the principal amount of a note by the last reported sale price of our common stock on the cover page of this offering memorandum.

(f) In case a tender offer or exchange offer (other than as part of a stock option exchange offer) made by the Company or any of its Subsidiaries for all or any portion of the Common Stock shall expire, then and in each such case, immediately prior to the opening of business on the day after the date of the last time (the “Expiration Time”) tenders or exchanges could have been made pursuant to such tender offer or exchange offer, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the date of the Expiration Time by a fraction:

(A)  the numerator of which shall be the sum of (x) the product of (i) the number of shares of Common Stock outstanding (excluding any tendered or exchanged shares) at the Expiration Time and (ii) the Current Market Price of the Common Stock at the Expiration Time, and (y) the Fair Market Value of the aggregate consideration payable to stockholders based on acceptance (up to any maximum specified in the terms of the tender offer or exchange offer) of all shares validly tendered and not withdrawn as of the Expiration Time; and

(B)   the denominator of which shall be the product of the number of shares of Common Stock outstanding (including any tendered or exchanged shares) at the Expiration Time and the Current Market Price of the Common Stock at the Expiration Time.
