     A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

     The Trustee shall authenticate and make available for delivery Securities for original issue in the aggregate principal amount of up to $103,500,000 (subject to Section 2.16) upon receipt of (i) a written order or orders of the Company signed by two Officers of the Company (a “Company Order”) and delivered to the Trustee, and (ii) an Officers’ Certificate and Opinion of Counsel pursuant to Section 13.04 hereof. Additional Securities may thereafter be issued pursuant to Section 2.16 hereof. Each Company Order shall specify the amount of Securities to be authenticated, shall provide that all Securities will be represented by a Global Security and the date on which each original issue of Securities is to be authenticated. The Trustee shall have the right to decline to authenticate and deliver any Securities under this Section if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders.

     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. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company.

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

     Section 2.03. Registrar, Paying Agent and Conversion Agent.

     The Company shall maintain one or more offices or agencies in The City of New York where Securities may be presented for registration of transfer or for exchange (each, a “Registrar”) or for conversion (each, a “Conversion Agent”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying Agent”) and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. One of the Registrars (the “Primary Registrar”) shall keep a register of the Securities and of their transfer and exchange.

     The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, or Conversion Agent, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Article 11).

     The Company hereby initially designates the Trustee as Paying Agent, Registrar, Securities Custodian and Conversion Agent, and the Corporate Trust Office of the Trustee to be such office or agency of the Company for each of the aforesaid purposes.

     Section 2.04. Paying Agent to Hold Money in Trust.

     Prior to 11:00 a.m. (New York City time) on each due date of the principal of or interest on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal and interest so becoming due. The Company shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee in writing of any default by the Company (or any other obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 11:00 a.m. (New York City time) on each due date of the principal of or interest on any Securities, segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money.

     Section 2.05. Securityholder 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 Primary Registrar, the Company shall furnish to the Trustee at least five Business Days before each semiannual interest payment date, and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

     Section 2.06. Transfer and Exchange.

     (a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to a 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, if applicable, any legal opinions, certifications or other evidence required by the Company pursuant to Section 2.12 and, if it is a Certificated Security, an assignment form in the form included in Exhibit A, all in form satisfactory to the Registrar 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 transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto; provided that this sentence shall not apply to any exchange pursuant to Section 2.10, 3.04, 5.02(d) or 12.05.

     None of the Company, any Registrar or the Trustee shall be required to exchange or register a transfer of any Securities or portions thereof (i) in respect of which a Fundamental

Change Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased) or (ii) surrendered for conversion pursuant to Article 5.

     All Securities issued upon any transfer or exchange of Securities 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 2.03 hereof 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) Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable U.S. federal or state securities law. Prior to the due presentment of a registration of a transfer of any Security, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Security is registered as the absolute owner of such Security for the purpose of all payments with respect to such Securities, and neither the Trustee, any Agent nor the Company shall be affected by notice to the contrary. Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary.

     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.

     Section 2.07. Replacement Securities.

     If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a 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 applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them from any loss they may suffer if a Security is replaced, then, in the absence of written notice to the Company, such 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 number not contemporaneously outstanding. The Trustee and the Company each may charge such Holder for their expenses in replacing such Security.

     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 purchased by the Company pursuant to Article 3, or

converted pursuant to Article 5, the Company in its discretion may, instead of issuing a new Security, pay, purchase or convert such Security, as the case may be.

     Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith.

     Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, 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 2.07 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

     Section 2.08. Outstanding Securities.

     Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those purchased pursuant to Article 3, those converted pursuant to Article 5, those delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding.

     If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Company receives, subsequent to the new Security’s authentication, proof satisfactory to the Company that the replaced Security is held by a bona fide purchaser unaware that such Security has been replaced.

     If a Paying Agent (other than the Company or an Affiliate of the Company) holds in respect of Securities on a Fundamental Change Purchase Date or the Maturity Date money sufficient to pay the principal of (including premium, if any), and any accrued interest on Securities (or portions thereof) payable on that date, then on and after such Fundamental Change Purchase Date or the Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding and any interest on them shall cease to accrue.

     Subject to the restrictions contained in Section 2.09, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

     Section 2.09. Treasury Securities.

     In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which

have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor.

     Section 2.10. Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities and as shall be reasonably acceptable to the Trustee. Every temporary Security shall be executed and registered by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities.

     Section 2.11. Cancellation.

     The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for transfer, exchange, redemption, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, payment, conversion or cancellation and shall deliver the canceled Securities to the Company. The Company may, to the extent permitted by law, purchase Securities in the open market or by tender offer at any price or by private agreement. Any Securities purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Maturity Date may, to the extent permitted by law, be reissued or resold or may, at the option of the Company, be surrendered to the Trustee for cancellation. Any Securities surrendered for cancellation may not be reissued or resold and shall be promptly cancelled by the Trustee, and the Company may not hold or resell such Securities or issue any new Securities to replace any such Securities or any Securities that any Holder has converted pursuant to Article 5.

     Section 2.12. Legends; Additional Transfer Requirements.

     (a) Every Security that bears or is required under this Section 2.12(a) to bear the Restricted Security Legend set forth in this Section 2.12(a) (the “Transfer Restricted Securities”) shall be subject to the restrictions on transfer set forth in Section 2.06 and this Section 2.12(a) (including those set forth in the Restricted Security Legend set forth below), and the Holder of each such Transfer Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in Sections 2.12(a) and 2.12(b), the term “transfer” includes any sale, pledge, transfer or other disposition whatsoever of any Transfer Restricted Security. The Registrar shall not register any transfer of a Transfer Restricted Security not made in accordance with the restrictions on transfer set forth in this Section 2.12.

     Subject to the last two paragraphs of this Section 2.12(a), prior to the date upon which the Trustee removes the Restricted Security Legend from any Security (the “Resale Restriction Termination Date,” which shall have a correlative meaning in respect of any Restricted Common Stock) any certificate evidencing such Security (and all securities issued in exchange therefor or substitution thereof, including Common Stock, if any, issued upon conversion thereof, which shall bear the legend set forth in Section 2.12(b), if applicable) shall bear a legend in substantially the following form:

“THIS SECURITY AND THE CLASS A COMMON STOCK, IF ANY, ISSUABLE UPON CONVERSION OF THIS SECURITY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

     1. REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

     2. AGREES FOR THE BENEFIT OF TELECOMMUNICATION SYSTEMS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE HEREOF OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THEREUNDER, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

          (A) TO THE COMPANY OR ANY OF ITS SUBSIDIARIES, OR

          (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

          (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

          (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRUSTEE RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO

DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT;”

     So long as the Securities are represented by Global Securities that are held by or on behalf of the Depositary only, the Company may accomplish any delegending of such Securities by:

     (i) instructing the Trustee to remove the Restricted Security Legend from the Securities and instructing the transfer agent for the Common Stock to remove the Restricted Stock Legend from the Common Stock issued upon conversion of the Securities;

     (ii) notifying Holders of the Securities and Common Stock issued upon conversion of the Securities that the Restricted Security Legend and Restricted Stock Legend have been removed or deemed removed;

     (iii) notifying the Trustee, the transfer agent for the Common Stock and DTC to change the CUSIP number for the Securities and the Common Stock issued upon conversion of the Securities to the applicable unrestricted CUSIP number; and

     (iv) complying with any Applicable Procedures for delegending;

whereupon the Restricted Security Legend shall be deemed removed from any Global Securities without further action on the part of Holders.

     Any Security (or security issued in exchange or substitution therefor) as to which the restrictions on transfer shall have expired in accordance with their terms or that has been transferred, replaced or exchanged on or after the Resale Restriction Termination Date or that has been transferred pursuant to a registration statement that has been declared effective under the Securities Act may, upon surrender of such Security to the Registrar for exchange in accordance with the provisions of this Section 2.12, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the Restricted Security Legend required by this Section 2.12(a).

     (b) Every stock certificate representing Common Stock issued upon conversion of a Transfer Restricted Security that bears or is required under this Section 2.12(b) to bear the Restricted Stock Legend set forth in this Section 2.12(b) (the “Transfer Restricted Common Stock”) shall be subject to the restrictions on transfer set forth in Section 2.06 and this Section 2.12(b) (including those set forth in the Restricted Stock Legend set forth below), and the Holder of such Common Stock issued upon conversion of a Transfer Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer and the further restrictions set forth in Section 2.15. The Company shall not register any transfer of Common Stock issued upon conversion of such a Transfer Restricted Security not made in accordance with the restrictions on transfer set forth in this Section 2.12.

     Subject to the last paragraph of this Section 2.12(b) and Section 2.15 with respect to Common Stock, prior to the Resale Restriction Termination Date, any stock certificate representing Common Stock issued upon conversion of a Transfer Restricted Security shall bear a legend in substantially the following form, unless such Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such issuance) or such Common Stock has been issued upon conversion of Securities that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act:

“THIS SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER:

     1. REPRESENTS THAT IT AND ANY ACCOUNT FOR WHICH IT IS ACTING IS A “QUALIFIED INSTITUTIONAL BUYER” (WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT) AND THAT IT EXERCISES SOLE INVESTMENT DISCRETION WITH RESPECT TO EACH SUCH ACCOUNT, AND

     2. AGREES FOR THE BENEFIT OF TELECOMMUNICATION SYSTEMS, INC. (THE “COMPANY”) THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SECURITY IN RESPECT OF THE CONVERSION OF WHICH THIS SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THEREUNDER, AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

     (A) TO THE COMPANY OR ANY OF ITS SUBSIDIARIES, OR

     (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

     (C) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, OR

     (D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY AND THE TRANSFER AGENT RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH

LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.”

     Any stock certificate (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms or that has been transferred, replaced or exchanged on or after the Resale Restriction Termination Date or that has been transferred pursuant to a registration statement that has been declared effective under the Securities Act may, upon surrender of such stock certificate to the transfer agent for the Common Stock for exchange in accordance with the provisions of this Section 2.12 and Section 2.15, be exchanged for a new stock certificate, of like tenor and aggregate number of shares, which shall not bear the Restricted Stock Legend required by this Section 2.12(b).

     (c) Any Security or Common Stock issued upon the conversion or exchange of a Security that, prior to the date upon which the Company instructs the Trustee to remove the Restricted Security Legend, is purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Security or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144).

     (d) Notwithstanding any provision of Section 2.06 and Section 2.12 to the contrary, in the event Rule 144(d) as promulgated under the Securities Act (or any successor rule) is amended to change the one-year period under Rule 144(d) (or the corresponding period under any successor rule), from and after receipt by the Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this Section 2.12(d), (i) each reference in Section 2.12(a) to “one year” and in the Restricted Security Legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period, (ii) each reference in Section 2.12(b) to “one year” and in the Restricted Stock Legend set forth in such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period and (iii) all corresponding references in the Security (including the definition of Resale Restriction Termination Date) and the Restricted Security Legend thereon shall be deemed for all purposes hereof to be references to such changed period, provided that such changes shall not become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the then-applicable federal securities laws. The provisions of this Section 2.12(d) shall not be effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by the Trustee hereunder. This Section 2.12(d) shall apply to successive amendments to Rule 144(d) (or any successor rule) changing the holding period thereunder.

     (e) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of

a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12.

     (f) The provisions of clauses (i), (ii), (iii) and (iv) below shall apply only to Global Securities:

     (i) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged for Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days or (B) an Event of Default has occurred and is continuing with respect to the Securities. Any Global Security exchanged pursuant to clause (A) shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security.

     (ii) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

     (iii) The registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

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

     Section 2.13. CUSIP Numbers.

     The Company in issuing the Securities may use one or more “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of purchase 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 purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” number.

     Section 2.14. Ranking.

     The obligations of the Company arising under or in connection with this Indenture and every outstanding Security issued under this Indenture from time to time constitute and shall constitute an unsecured general obligation of the Company, ranking equal in right of payment to all other existing and future senior unsecured and unsubordinated indebtedness of the Company and ranking senior in right of payment to any future indebtedness of the Company that is expressly made subordinate to the Securities by the terms of such indebtedness.

     Section 2.15. Issuance, Transfer and Exchange of Common Stock Issuable Upon Conversion of the Securities.

     If (i) shares of Common Stock to be issued upon conversion of Securities bearing the Restricted Security Legend are to be registered in a name other than that of the Holder of such Securities or (ii) shares of Common Stock represented by a certificate bearing the Restricted Stock Legend are transferred subsequently by such Holder, then the Holder must deliver to the transfer agent for the Common Stock and to the Company a certificate in substantially the form of Exhibit B as to compliance with the restrictions on transfer applicable to such shares of Common Stock and neither the transfer agent nor the registrar for the Common Stock shall be required to register any transfer of such Common Stock not so accompanied by a properly completed certificate.

     Section 2.16. Additional Securities.

     (a) The Company may, from time to time without the consent of the Holders of outstanding Securities, increase the aggregate principal amount of the Securities by issuing additional Securities in the future pursuant to this Indenture (“Additional Securities”) having terms and conditions identical to those of the other outstanding Securities, except that Additional Securities may have a different initial date from which interest begins to accrue thereon so that the Additional Securities are fungible with outstanding Securities; provided that no differences pursuant to this Section 2.16(a) shall cause such Additional Securities to constitute a different class of securities than the Securities issued on the Initial Issue Date for U.S. federal income tax purposes; and provided, further, that the Additional Securities shall have the same CUSIP number as the Securities issued on the Initial Issue Date. The Securities issued on the Initial Issue Date and any Additional Securities shall be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, offers to purchase and U.S.

federal income tax purposes. No Additional Securities may be issued if on the issue date therefor any Event of Default has occurred and is continuing.

     (b) With respect to any Additional Securities, the Company shall set forth in an Officers’ Certificate pursuant to a resolution of the Board of Directors of the Company, copies of which shall be delivered to the Trustee, the following information:

     (i) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture;

     (ii) the issue date and the issue price of such Additional Securities;

     (iii) whether such Additional Securities will be subject to transfer restrictions under the Securities Act (or other applicable securities laws).

In addition, the Company shall deliver to the Trustee an Opinion of Counsel in accordance with Section 13.04 hereof certifying as to the satisfaction of all conditions precedent to the authentication by the Trustee of such Additional Securities.

     Section 2.17. Additional Interest.

     The Company may be obligated to pay Additional Interest to Holders, as and to the extent set forth in accordance with Section 7.10 and Section 9.02(b) hereof. Any Additional Interest is deemed to be interest for purposes of this Indenture. The Trustee has no duty to determine when Additional Interest under Section 7.10 or Section 9.02(b) hereof should be paid.

     Section 2.18. Calculations in Respect of Securities.

     Except to the extent provided herein and therein, the Company will be responsible for making all calculations called for under the Indenture and the Securities. These calculations include, but are not limited to, determinations of the Closing Sale Price of the Common Stock, adjustments to the Conversion Price, any accrued interest payable on the Securities, the Conversion Price and the Conversion Rate. The Company will make these calculations in good faith and, absent manifest error, the calculations will be final and binding on Holders of the Securities. The Company will provide to each of the Trustee and the Conversion Agent a schedule of its calculations, and the Trustee and the Conversion Agent are entitled to rely conclusively upon the accuracy of such calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of the Securities upon the request of such Holder.

     Section 3.01. Purchase of Securities at Option of the Holder Upon Fundamental Change.

     (a) If at any time that Securities remain outstanding there shall occur a Fundamental Change, Securities shall be purchased by the Company at the option of the Holders, as of a date, determined by the Company in its sole discretion, that is not less than 20 Business Days and not more than 35 Business Days after the occurrence of the Fundamental Change (the “Fundamental Change Purchase Date”) at a purchase price equal to 100% of the principal amount of the Securities to be purchased, together with any accrued and unpaid interest to, but excluding, the Fundamental Change Purchase Date (the “Fundamental Change Purchase Price”), unless the Fundamental Change Purchase Date is after a Record Date and on or prior to the related Interest Payment Date, in which case interest accrued to the Interest Payment Date will be paid to Holders of the Securities as of the preceding Record Date and the Fundamental Change Purchase Price payable to any Holder surrendering such Holder’s Security for purchase pursuant to this Article 3 shall be equal to the principal amount of Securities subject to purchase and will not include any accrued and unpaid interest. The Fundamental Change Purchase Price shall be payable in Cash, subject to satisfaction by or on behalf of any Holder of the requirements set forth in subsection (c) of this Section 3.01. Notwithstanding the foregoing, the Company may not repurchase the Securities upon the occurrence of a Fundamental Change if the principal amount of the Securities has been accelerated and such acceleration has not been rescinded on or prior to the Fundamental Change Purchase Date.

     A “Fundamental Change” shall mean the occurrence of a Change in Control or a Termination of Trading.

     A “Change in Control” shall be deemed to have occurred if any of the following occurs after the date hereof:

     (i) any “person” or “group” (as such terms are defined below) is or becomes the “beneficial owner” (as defined below), directly or indirectly, of shares of Voting Stock of the Company representing 50% or more of the total voting power of all outstanding classes of Voting Stock of the Company or has the power, directly or indirectly, to elect a majority of the members of the Board of Directors; or

     (ii) the Company consolidates with, enters into a binding share exchange with, or merges with or into, another Person or the Company sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of the assets of the Company, or any Person consolidates with, or merges with or into, the Company, in any such event other than pursuant to a transaction (A) in which the Persons that “beneficially owned”, directly or indirectly, shares of Voting Stock of the Company immediately prior to such transaction “beneficially own”, directly or indirectly, shares of Voting Stock of the Company representing at least a majority of the total voting power of all outstanding classes of Voting Stock of the surviving or transferee Person, with such Holders’ proportional voting power immediately after such transaction vis-à-vis each other with respect to the securities they receive in such transaction being in substantially the same proportions as their respective voting power vis-à-vis each other immediately prior to such transaction, or (B) which is effected solely to change the jurisdiction of

incorporation of the Company and results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of common stock of the surviving Person; or; or

     (iii) a majority of the members of the Board of Directors are not Continuing Directors; or

     (iv) the holders of the Capital Stock of the Company approve any plan or proposal for the liquidation or dissolution of the Company (whether or not otherwise in compliance with the terms hereof).

     For the purpose of the definition of “Change in Control”, (i) “person” and “group” have the meanings given such terms under Section 13(d) and 14(d) of the Exchange Act or any successor provision to either of the foregoing, and the term “group” includes any group acting for the purpose of acquiring, holding, voting or disposing of securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor provision thereto), (ii) a “beneficial owner” shall be determined in accordance with Rule 13d-3 under the Exchange Act, as in effect on the date of this Indenture, except that the number of shares of Voting Stock of the Company shall be deemed to include, in addition to all outstanding shares of Voting Stock of the Company and Unissued Shares deemed to be held by the “person” or “group” (as such terms are defined above) or other Person with respect to which the Change in Control determination is being made, all Unissued Shares deemed to be held by all other Persons, and (iii) the terms “beneficially owned” and “beneficially own” shall have meanings correlative to that of “beneficial owner”. The term “Unissued Shares” means shares of Voting Stock not outstanding that are subject to options, warrants, rights to purchase or conversion privileges exercisable within 60 days of the date of determination of a Change in Control.

     Notwithstanding anything to the contrary set forth in this Section 3.01, Holders shall not have the right to require the Company to purchase any Securities in the event of a Change of Control resulting from the occurrence of an event described in clauses (i) and (ii) of the definition of such term, and the Company shall not be required to deliver a written notice of a Fundamental Change incidental thereto as a result of any acquisition, consolidation, merger or binding share exchange or a sale, assignment, conveyance, transfer, lease or other disposition if at least 90% of the consideration paid for the Common Stock (excluding cash payments for fractional shares and cash payments pursuant to dissenters’ appraisal rights) in such transaction or transactions consists of shares of common stock that are traded on the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors) or which will be so traded immediately following such transaction or transactions and as a result of such transaction or transactions the Securities become convertible into such shares of such common stock.

     A “Termination of Trading” means that the Common Stock or other securities into which the Securities are convertible are not approved for listing on the New York Stock Exchange, the NASDAQ Global Select Market or the NASDAQ Global Market (or any of their respective successors).

     If any transaction in which the Common Stock is replaced by the securities of another entity occurs, following completion of any related Make Whole Adjustment Event Period and any related Fundamental Change Purchase Date, references to the Company in the definitions of “Fundamental Change,” “Change of Control” and “Termination of Trading” above shall apply to such other entity instead.

     (b) Within 10 Business Days after the occurrence of a Fundamental Change, the Company shall mail a written notice of the Fundamental Change to the Trustee and to each Holder. The Company shall also issue a press release announcing the occurrence of such Fundamental Change (and make such press release available on the Company’s website). The notice shall include the form of a Fundamental Change Purchase Notice to be completed by the Holder and shall state:

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

     (ii) the Effective Date of the Fundamental Change, and whether the Fundamental Change is a Make Whole Adjustment Event, in which case the Effective Date of the Make Whole Adjustment Event;

     (iii) information about the Holders’ right to convert the Securities;

     (iv) information about the Holders’ right to require the Company to purchase the Securities;

     (v) the last date on which a Holder may exercise the purchase right;

     (vi) the Fundamental Change Purchase Date;

     (vii) the Fundamental Change Purchase Price;

     (viii) the date by which the Fundamental Change Purchase Notice pursuant to this Section 3.01 must be given;

     (ix) the Conversion Price (giving effect to any applicable Additional Shares) and any adjustments thereto;

     (x) the procedures that the Holder must follow to exercise rights under this Section 3.01;

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

     (xii) the name and address of each Paying Agent and Conversion Agent;

     (xiii) that the Holder must satisfy the requirements set forth in the Indenture and the Securities in order to convert the Securities.

     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 repurchase of Global Securities.

     (c) A Holder may exercise its rights specified in subsection (a) of this Section 3.01 upon delivery of a written notice (which shall be in substantially the form included in Exhibit A hereto and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other manner reasonably acceptable to the Paying Agent 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 any Paying Agent during the period between the mailing of the Fundamental Change Purchase Notice and the close of business on the second Scheduled Trading Day next preceding the Fundamental Change Purchase Date.

     The delivery of such Security to any Paying Agent (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price therefor.

     The Company shall purchase from the Holder thereof, pursuant to this Section 3.01, 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 3.01 through Section 3.04 also apply to the purchase of such portion of such Security.

     Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Fundamental Change Purchase Notice contemplated by this subsection (c) shall have the right to withdraw such Fundamental Change Purchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to 5:00 p.m. (New York City time) on the second scheduled Trading Day next preceding the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.02.

     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.

     Section 3.02. Effect of Fundamental Change Purchase Notice.

     Upon receipt by any Paying Agent of the Fundamental Change Purchase Notice specified in Section 3.01(c), the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Fundamental Change Purchase Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such Holder promptly following the later of (a) the Fundamental Change Purchase Date

with respect to such Security (provided the conditions in Section 3.01(c) have been satisfied) and (b) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock pursuant to Article 5 on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has first been validly withdrawn.

     A Fundamental Change Purchase Notice may be withdrawn by means of a written notice (which may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other manner reasonably acceptable to the Paying Agent and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s customary procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to 5:00 p.m. (New York City time) on the second Scheduled Trading Day immediately preceding the Fundamental Change Purchase Date, specifying the principal amount of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted.

     Section 3.03. Deposit of Fundamental Change Purchase Price.

     On or before 11:00 a.m. (New York City time) on the Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent (other than the Company or an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Fundamental Change Purchase Date) sufficient to pay the aggregate Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of such Fundamental Change Purchase Date. The manner in which the deposit required by this Section 3.03 is made by the Company shall be at the option of the Company; provided that such deposit shall be made in a manner reasonably acceptable to the Trustee and the Paying Agent such that the Trustee or a Paying Agent shall have immediately available funds on the Fundamental Change Purchase Date.

     If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Fundamental Change Purchase Price of any Security for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture, then, on the Fundamental Change Purchase Date, such Security shall cease to be outstanding, interest shall cease to accrue thereon and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Fundamental Change Purchase Price as aforesaid). 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.

     To the extent that the aggregate amount of Cash deposited by the Company pursuant to this Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess Cash to the Company.

     Section 3.04. Securities Purchased in Part.

     Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent and, promptly after the Fundamental Change Purchase Date, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such authorized denomination or denominations as may be requested by such Holder, in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased.

     Section 3.05. Compliance with Securities Laws Upon Purchase of Securities.

     In connection with any offer to purchase Securities under Section 3.01, the Company shall (a) comply with the applicable provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or report), if required, under the Exchange Act and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or repurchase Securities, all so as to permit the rights of the Holders and obligations of the Company under Section 3.01 through Section 3.04 to be exercised in the time and in the manner specified therein.

     Section 3.06. No Fundamental Change Repurchase Following Acceleration.

     No Securities shall be purchased by the Company under Section 3.01 if the principal amount of the Securities has been accelerated under Section 9.02, and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date.

     Section 3.07. Trustee’s Fundamental Change Purchase Disclaimer.

     The Trustee has no duty to determine when a Fundamental Change has occurred, or when purchases of Securities upon a Fundamental Change under Article 3 should be made. The Trustee shall not be accountable for and makes no representation as to the Fundamental Change Purchase Price payable in respect of any Fundamental Change. The Trustee shall not be responsible for the Company’s failure to comply with this Article 3.

ARTICLE 4

PAYMENT OF INTEREST AND ADDITIONAL SHARES

     Section 4.01. Interest Payments.

     (a) The Company shall pay interest on the Securities at a rate of 4.5% per annum, payable semi-annually in arrears on May 1 and November 1 of each year (each, an “Interest Payment Date”), or if any such day is not a Business Day, the immediately following Business Day, commencing May 1, 2010. Interest on a Security shall be paid to the Holder of such Security at the close of business on April 15 or October 15 (each, a “Record Date”), as the case may be, next preceding the related Interest Payment Date, and shall be computed on the basis of a 360-day year comprised of twelve 30-day months. In the event of the maturity, conversion, or purchase of a Security by the Company at the option of the Holder, interest shall cease to accrue on such Security. Notwithstanding any other provision of this Indenture, however, the Company

shall pay interest on the Maturity Date to Holders on the Record Date immediately preceding the Maturity Date in respect of the period ending with the Maturity Date regardless of whether such Holders convert their Securities.

     (b) Upon conversion of a Security, (i) a Holder shall not receive any Cash payment of interest (unless such Holder is the Holder on a Record Date and such conversion occurs between such Record Date and the Interest Payment Date to which it relates, in which case a Holder on the Record Date shall receive on the Interest Payment Date accrued and unpaid interest) and the Conversion Rate shall not be adjusted to account for accrued and unpaid interest and (ii) except as set forth in clause (c) below, the Company’s delivery to a Holder of Common Stock and (in the case of fractional shares) Cash in settlement of the Conversion Obligation as set forth in Section 5.05 shall be deemed to satisfy its obligation with respect to such Security, and any accrued but unpaid interest shall be deemed to be paid in full upon conversion, rather than cancelled, extinguished or forfeited.

     (c) Securities surrendered for conversion by a Holder after the close of business on any Record Date but prior to the next Interest Payment Date must be accompanied by payment of an amount equal to the interest that shall be payable on the Securities; provided, however, that no such payment need be made (1) if the Company has specified a Fundamental Change Purchase Date that is after a Record Date and on or prior to the next Interest Payment Date, (2) with respect to any Securities surrendered for conversion following the Record Date for the payment of interest immediately preceding the Maturity Date or (3) only to the extent of overdue interest, if any overdue interest exists at the time of conversion with respect to such Securities.

     Section 4.02. Additional Shares.

     (a) Notwithstanding anything herein to the contrary, in the event a Holder elects to surrender its Securities for conversion in accordance with Article 5, at any time from, and including, the Effective Date of a Make Whole Adjustment Event to, and including, the close of business on the second Scheduled Trading Day immediately preceding the related Fundamental Change Purchase Date, or (in the case of a Make Whole Adjustment Event that does not also constitute a Fundamental Change) the 40th Scheduled Trading Day immediately following the Effective Date of such Make Whole Adjustment Event (such period, the “Make Whole Adjustment Event Period”), the Company will increase the Conversion Rate for the Securities surrendered for conversion by the applicable number of additional shares of Common Stock set forth in Schedule 4.02 (the “Additional Shares”), as described in this Section 4.02.

     (b) For purposes of determining the applicable number of Additional Shares pursuant to Schedule 4.02:

     (i) “Effective Date” shall mean the date the Make Whole Adjustment Event occurs or becomes effective; and

     (ii) “Stock Price” shall mean:

     (x) in the case of a Make Whole Adjustment Event described in clause (ii) of the definition of Change in Control in which the holders of

Common Stock receive only Cash in such Make Whole Adjustment Event, the Cash amount paid or deemed paid per share of Common Stock in such Change of Control converted, if necessary, into U.S. dollars at the exchange rate in effect on such date; or

     (y) in the case of any other Make Whole Adjustment Event, the average of the last reported Closing Sale Price over the five consecutive Trading Day period ending on the Trading Day immediately preceding the Effective Date of such other Make Whole Adjustment Event.

     (c) If the Stock Price is between two Stock Price amounts in the table attached as Schedule 4.02 hereto, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts, based on a 365-day year.

     (d) If the Effective Date falls between two Effective Dates in the table attached as Schedule 4.02 hereto, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the two dates, based on a 365-day year.

     (e) No increase in the Conversion Rate shall be made pursuant to this Section 4.02 if the Stock Price (i) exceeds $36.00 per share (subject to adjustment) or (ii) is less than $7.96 per share (subject to adjustment).

     (f) The Stock Price amounts set forth in the first row of the table (i.e., column headers) in Schedule 4.02 hereto shall be adjusted as of any date on which the Conversion Price of the Securities is adjusted pursuant to Section 5.06. The Stock Price amounts set forth in the table shall be adjusted by the same adjustment factor applied to the Conversion Price pursuant to Section 5.06. The number of Additional Shares indicated in the table shall be adjusted by the inverse of the adjustment factor applied to the Conversion Price pursuant to Section 5.06.

     (g) In no event shall the Conversion Rate be increased to more than 125.616 shares per $1,000 principal amount of Securities (the “Maximum Conversion Rate”) pursuant to the events described in this Section 4.02. The Maximum Conversion Rate shall be adjusted as of any date on which the Conversion Price of the Securities is adjusted pursuant to Section 5.06, by the inverse of the adjustment factor applied to the Conversion Price pursuant to such section.

     (h) The Company shall use commercially reasonable efforts to notify Holders of the anticipated Effective Date of a Make Whole Adjustment Event not less than 10 Scheduled Trading Days prior to the anticipated Effective Date of such Make Whole Adjustment Event.

ARTICLE 5

CONVERSION

     Section 5.01. Conversion Privilege.

     (a) Subject to the further provisions of this Article 5 and paragraph 6 of the Securities, a Holder may surrender a Security for conversion at any time prior to the close of business on the second Scheduled Trading Date immediately preceding the Maturity Date.

     (b) A Security in respect of which a Holder has delivered a Fundamental Change Purchase Notice pursuant to Section 3.01(c) exercising the option of such Holder to require the Company to purchase such Security may be converted only if such Fundamental Change Purchase Notice is withdrawn by a written notice of withdrawal delivered to a Paying Agent prior to 5:00 p.m. (New York City time) on the second Scheduled Trading Day immediately preceding the Fundamental Change Purchase Date in accordance with Section 3.02.

     (c) Securities may be surrendered for conversion only in principal amounts that are integral multiples of $1,000.

     Section 5.02. Conversion Procedure.

     (a) The right to convert any Security may be exercised only if such Holder shall (i) in the case of a Global Security, comply with the Applicable Procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.01(c) and, if required, all transfer or similar taxes, if any, and (ii) in the case of a Certificated Security, (1) complete and manually sign and deliver an irrevocable notice to the Conversion Agent in the form on the reverse of such Certificated Security (or a facsimile thereof) (included in Exhibit A hereto) (a “Notice of Conversion”) at the office of the Conversion Agent and state in writing therein the principal amount of Securities to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock, if any, to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Securities, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 4.01(c), (4) if required, furnish appropriate endorsements and transfer documents, and (5) if required, pay all transfer or similar taxes, if any, as set forth in Section 5.04. The Trustee (and if different, the relevant Conversion Agent) shall notify the Company of any conversion pursuant to this Article 5 on the date of such conversion. No Notice of Conversion with respect to any Securities may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Securities and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Article 3.

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

     (b) A Security shall be deemed to have been converted (the “Conversion Date”) immediately prior to the close of business on the date that the Holder has complied with the requirements set forth in Section 5.02(a), if such requirements are satisfied by 11:00 a.m. (New York City time) on that date, or immediately prior to the close of business on the next succeeding Business Day if such requirements are satisfied after 11:00 a.m. (New York City time) on that date.

     (c) The Company shall cause the Holder of such Securities on the Conversion Date to become the holder of record of the deliverable number of shares of Common Stock constituting the Conversion Obligation on the Conversion Date. The Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock to which such Holder shall be entitled in satisfaction of such Conversion Obligation.

     (d) In case any 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, a new Security or Securities in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Security.

     (e) Except as provided in Section 5.06, no adjustment shall be made for dividends on any shares issued upon the conversion of any Security as provided in this Article.

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

     (g) The Person in whose name the certificate for any shares of Common Stock delivered upon conversion is registered shall be treated as a stockholder of record as of the close of business on the relevant Conversion Date.

     (h) The Company shall not be required to deliver any Additional Shares pursuant to Section 4.02 hereof until the Effective Date of the Make Whole Adjustment Event causing such increase has occurred. The Company shall deliver the Additional Shares as soon as practicable, but in no event after the third Business Day after the later of:

     (i) the Conversion Date; and

     (ii) the Effective Date of the Make Whole Adjustment Event.

     Section 5.03. Fractional Shares.

     The Company shall not issue fractional shares of Common Stock upon conversion of Securities. In lieu thereof, the Company shall deliver Cash equal to the remainder multiplied by the Closing Sale Price of Common Stock on the relevant Conversion Date.

     Section 5.04. Taxes on Conversion.

     If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificate representing the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which shall be due because the shares are to be issued in a name other than the Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

     Section 5.05. Issuance of Common Stock Upon Conversion.

     (a) Subject to Section 5.02, upon any conversion of any Security, the Company shall deliver to converting Holders on the third Business Day immediately following the relevant Conversion Date (unless such Conversion Date occurs on or following August 1, 2014, in which case the Company shall make such delivery on the Maturity Date), in respect of each $1,000 principal amount of Securities being converted, the number of shares of Common Stock (the “Conversion Obligation”) equal to the then applicable Conversion Rate. The Company shall also deliver to each converting Holder of the Securities Cash in lieu of fractional shares of Common Stock as set forth pursuant to Section 5.03.

     (b) The Company shall, prior to the issuance of any Securities hereunder, and from time to time as may be necessary, reserve at all times and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock deliverable upon conversion of all of the Securities.

     (c) All shares of Common Stock that may be issued upon conversion of the Securities shall be duly authorized, validly issued, fully paid and nonassessable and shall be free of any preemptive rights and free of any lien or adverse claim.

     (d) The Company shall endeavor to comply with all applicable securities laws regulating the offer and delivery of any Common Stock upon conversion of Securities and shall list or cause to have quoted such shares of Common Stock on each national or regional securities exchange or other over-the-counter market or such other market on which the Common Stock is then listed or quoted; provided, however, that, if the rules of such automated quotation system or exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon conversion of the Securities in accordance with the requirements of such automated quotation system or exchange at such time. Any Common Stock issued upon conversion of a Security hereunder which at the time of conversion was a Transfer Restricted Security shall also be a Transfer Restricted Security.

     (e) Notwithstanding anything herein to the contrary, nothing herein shall give to any Holder any rights as a creditor in respect of its right to conversion.

     Section 5.06. Adjustment of Conversion Price.

     The conversion price as stated in paragraph 6 of the Securities (the “Conversion Price”) shall be adjusted from time to time by the Company as follows:

     (a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all of the shares Common Stock, or if the Company subdivides or combine outstanding shares of Common Stock, the Conversion Price will be adjusted based on the following formula:

		CP = CP0 ×		OS0
				OS

     where,

     CP₀ = the conversion price in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such subdivision or combination of Common Stock, as the case may be;

     CP = the Conversion Price in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date of such subdivision or combination of Common Stock, as the case may be;

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

     OS = the number of shares of Common Stock outstanding immediately after such dividend or distribution, or immediately after the effective date of such subdivision or combination of Common Stock, as the case may be.

     Such adjustment shall become effective immediately after the opening of business on the Ex-Dividend Date for such dividend or distribution or the effective date for such subdivision or combination of Common Stock. If any dividend or distribution of the type described in this Section 5.06(a) is declared but not so paid or made, or the outstanding shares of Common Stock are not split or combined, as the case may be, the Conversion Price shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, or subdivide or combine the outstanding shares of Common Stock, as the case may be, to the Conversion Price that would then be in effect if such dividend, distribution, subdivision or combination of Common Stock had not been declared or announced.

     (b) If the Company distributes to all or substantially all holders of Common Stock any rights, options or warrants entitling them for a period of not more than 60 calendar days from the record date for such distribution to subscribe for or purchase shares of the Common Stock (or securities convertible into Common Stock), at a price per share (or a conversion price per share)

less than the average of the Closing Sale Prices for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution, the Conversion Price will be decreased based on the following formula:

		CP = CP0 ×		OS0 + Y
				OS0 + X

     where,

     CP₀ = the Conversion Price in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

     CP = the Conversion Price in effect immediately after the open of business on the Ex-Dividend Date for such distribution;

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

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

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

     Such adjustment shall be successively made whenever any such rights, options or warrants are distributed and shall become effective immediately after the opening of business on the Ex-Dividend Date for each such distribution. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Price shall be readjusted to the Conversion Price that would then be in effect had the adjustments made upon the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, the Conversion Price shall again be adjusted to be the Conversion Price that would then be in effect if such Ex-Dividend Date for such distribution had not been fixed.

     For purposes of this Section 5.06(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than the average of the Closing Sale Prices for each Trading Day in the applicable 10-consecutive Trading Day period, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. In no event shall the Conversion Price be increased pursuant to this Section 5.06(b).

     (c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company to all or substantially all holders of Common Stock other than (i) dividends or distributions (including subdivision of Common

Stock) covered by Section 5.06(a) or Section 5.06(b), (ii) dividends or distributions paid exclusively in cash referred to in Section 5.06(d), (iii) Spin-Offs to which the provisions set forth below in this Section 5.06(c) shall apply, and (iv) distributions of rights to all or substantially all holders of Common Stock pursuant to the adoption of a shareholder rights plan, then, in each such case the Conversion Price shall be decreased based on the following formula:

		CP = CP0 ×		SP0 - FMV
				SP0

     where,

     CP₀ = the Conversion Price in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

     CP = the Conversion Price in effect immediately after the open of business on the Ex-Dividend Date for such distribution;

     SP₀ = the average of the Closing Sale Prices over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

     FMV = the Fair Market Value of the shares of Capital Stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Common Stock as of the open of business on the Ex-Dividend Date for such distribution.

     If the then- Fair Market Value of the portion of the shares of Capital Stock, evidences of indebtedness or other assets or property so distributed applicable to one share of Common Stock is equal to or greater than the average of the Closing Sale Prices over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution, in lieu of the foregoing adjustment, adequate provisions shall be made so that each Holder of a Security shall have the right to receive on conversion in respect of each Security held by such Holder, in addition to the number of shares of Common Stock that such Holder is entitled to receive, the amount and kind of securities and assets such Holder would have received had such Holder already owned a number of shares of Common Stock equal to the Conversion Rate immediately prior to the record date for the distribution of the securities or assets.

     With respect to an adjustment pursuant to this Section 5.06(c) where there has been a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company (a “Spin-Off”), the Conversion Price will be decreased based on the following formula:

		CP = CP0 ×		MP0
				FMV + MP0

     where,

     CP₀ = the Conversion Price in effect immediately prior to the open of business on the Ex-Dividend Date for the Spin-Off;

     CP = the Conversion Price in effect immediately after the open of business on the Ex-Dividend Date for the Spin-Off;

     FMV = the average of the closing sale prices of the Capital Stock or similar equity interests distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period immediately following, and including, the Ex-Dividend Date for the Spin-Off (such period, the “Valuation Period”); and

     MP₀ = the average of the Closing Sale Price of the Common Stock over the Valuation Period.

     The adjustment to the Conversion Price under the preceding paragraph of this Section 5.06(c) shall be made immediately after the open of business on the day after the last day of the Valuation Period, but shall become effective as of the open of business on the Ex-Dividend Date for the Spin-Off. For purposes of determining the Conversion Price, in respect of any conversion during the 10 Trading Days commencing on the Ex-Dividend Date of any Spin-Off, references in the portion of this Section 5.06(c) related to Spin-Offs to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for such Spin-Off to, but excluding, the Conversion Date for such conversion.

     For purposes of this Section 5.06(c), Section 5.06(a) and Section 5.06(b), any dividend or distribution to which this Section 5.06(c) is applicable that also includes shares of Common Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which Section 5.06(a) or Section 5.06(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets or shares of Capital Stock other than such shares of Common Stock or rights, options or warrants to which this Section 5.06(c) applies (and any Conversion Price adjustment required by this Section 5.06(c) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights, options or warrants (and any further Conversion Price adjustment required by Section 5.06(a) and Section 5.06(b) with respect to such dividend or distribution shall then be made), except (A) the Ex-Dividend Date of such dividend or distribution shall be substituted as “the Ex-Dividend Date,” “the Ex-Dividend Date relating to such distribution of such rights, options or warrants” and “the Ex-Dividend Date for such distribution” within the meaning of Section 5.06(a) and Section 5.06(b) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed “outstanding immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such subdivision or share combination, as the case may be” within the meaning of Section 5.06(a) or “outstanding immediately prior to the Ex-Dividend Date for such distribution” within the meaning of Section 5.06(b).

     In no event shall the Conversion Price be increased pursuant to this Section 5.06(c).

     (d) If the Company makes or pays any cash dividend or distribution to all or substantially all holders of outstanding Common Stock (other than distributions pursuant to Section 5.06(e) and any dividend or distribution in connection with the liquidation, dissolution or winding up on the Company), the applicable Conversion Price shall be decreased based on the following formula:

		CP = CP0 ×		SP0 - C
				SP0

     where,

     CP₀ = the Conversion Price in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

     CP = the Conversion Price in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

     SP₀ = the average of the Closing Sale Prices for the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

     C = the amount in cash per share the Company pays or distributes to holders of Common Stock.

     If any dividend or distribution described in this Section 5.06(d) is declared but not so paid or made, the new Conversion Price shall again be readjusted to be the Conversion Price that would then be in effect if such dividend or distribution had not been declared.

     For the avoidance of doubt, for purposes of this Section 5.06(d), in the event of any reclassification of the Common Stock, as a result of which the Securities become convertible into more than one class of common stock, if an adjustment to the Conversion Price is required pursuant to this Section 5.06(d), references in this Section to one share of Common Stock or Closing Sale Prices of one share of Common Stock shall be deemed to refer to a unit or to the price of a unit consisting of the number of shares of each class of common stock into which the Securities are then convertible equal to the number of shares of such class issued in respect of one share of Common Stock in such reclassification. The above provisions of this paragraph shall similarly apply to successive reclassifications.

     In no event shall the Conversion Price be increased pursuant to this Section 5.06(d).

     (e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock and if the Cash and value of any other consideration included in the payment per share of the Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the 10 consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders

or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), the Conversion Price shall be decreased based on the following formula:

		CP = CP0 ×		OS0 × SP
				AC + (OS × SP)

     where,

     CP₀ = the Conversion Price in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;

     CP = the Conversion Price in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;

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

     OS₀ = the number of shares of Common Stock (including Class B common stock on an as converted basis) outstanding immediately prior to the time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer);

     OS = the number of shares of Common Stock (including Class B common stock on an as converted basis) outstanding immediately after the Expiration Time (after giving effect to such tender offer or exchange offer); and

     SP = the average of the Closing Sale Prices of Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

     Such adjustment under this Section 5.06(e) shall become effective at the opening of business on the Trading Day next succeeding the Expiration Date. For purposes of determining the Conversion Price, in respect of any conversion during the 10 Trading Days commencing on the Trading Day next succeeding the Expiration Date, references within this Section 5.06(e) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the Expiration Date to, but excluding, the Conversion Date for such conversion. If the Company is obligated to purchase shares pursuant to any such tender or exchange offer, but the Company is permanently prevented by applicable law from effecting any or all or any portion of such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that had been effected. In no event shall the Conversion Price be increased pursuant to this Section 5.06(e).

     (f) Notwithstanding this Section 5.06 or any other provision of this Indenture or the Securities, if any Conversion Price adjustment becomes effective, or any Ex-Dividend Date for

any issuance, dividend or distribution (relating to a required Conversion Price adjustment) occurs on a Conversion Date, the Board of Directors shall make adjustments to the Conversion Price and the amount of cash or number of shares of Common Stock issuable upon conversion of the Securities, as the case may be, as are necessary or appropriate to effect the intent of this Section 5.06 and the other provisions of this Article 5 and to avoid unjust or inequitable results, as determined in good faith by the Board of Directors. Any adjustment made pursuant to this Section 5.06(f) shall apply in lieu of the adjustment or other term that would otherwise be applicable.

     (g) If the Company adjusts the Conversion Price pursuant to the above provisions, the Company will deliver to the Conversion Agent a certificate setting forth the Conversion Price, detailing the calculation of the Conversion Price and describing the facts upon which the adjustment is based. In addition, the Company will issue a press release containing the relevant information and make the press release available on its website.

     Section 5.07. No Adjustment.

     (a) All calculations and other determinations under this Article 5 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share. Notwithstanding the provisions of Section 5.06, no adjustment in the Conversion Rate shall be required unless the adjustment would result in a change of at least 1% in the Conversion Price as last adjusted; provided, however, that any adjustments which by reason of this Section 5.07 are not required to be made shall be carried forward and taken into account in any subsequent adjustment, regardless of whether the aggregate adjustment is less than 1%, (i) upon any conversion of Securities, (ii) upon any required purchases of the Securities in connection with a fundamental change, and (iii) with respect to any conversions occurring after August 15, 2014, as the case may be.

     (b) No adjustment to the Conversion Rate shall be required in respect of any transaction in which Holders participate (as a result of holding the Securities, at the same time as holders of the Common Stock participate) as if such Holders held the number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount of Securities held by such Holder, divided by 1,000, without conversion of the Securities.

     (c) No adjustment to the Conversion Rate shall be required upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

     (d) No adjustment to the Conversion Rate shall be required upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of, or assumed by, us or any of our subsidiaries;

     (e) No adjustment to the Conversion Rate shall be required upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in Section 5.07(d) and outstanding as of the date the Securities were first issued.

     (f) No adjustment to the Conversion Rate shall be required for a change in the par value of the Common Stock.

     (g) No adjustment to the Conversion Rate shall be required for accrued and unpaid interest, if any.

     Section 5.08. Adjustment for Tax Purposes.

     The Company shall be entitled to make such reductions in the Conversion Price, for the remaining term of the Securities or any shorter term, in addition to those required by Section 5.06, as the Board of Directors shall determine to be advisable in order to avoid or diminish any tax to any holders of shares of Common Stock or rights to purchase Common Stock resulting from any stock dividends, subdivisions of shares, distributions of rights or warrants to purchase or subscribe for stock or securities, distributions of securities convertible into or exchangeable for stock hereafter made by the Company to its stockholders or from any event treated as such for income tax purposes.

     Section 5.09. Temporary Reduction of Conversion Price.

     To the extent permitted by applicable law, the Company from time to time may reduce the Conversion Price by any amount for any period of time if the period is at least 20 Business Days, the reduction is irrevocable during such period, and the Board of Directors shall have made a determination that such reduction would be in the best interest of the Company. Whenever the Conversion Price is reduced pursuant to the preceding sentence, the Company shall provide notice of any reduction in the Conversion Price to the Holders in the manner provided in Section 13.02, with a copy to the Trustee and Conversion Agent, at least 15 days prior to the date such reduced Conversion Price takes effect, and such notice shall state the reduced Conversion Price and the period during which it will be in effect.

     Section 5.10. Notice of Certain Transactions.

     In the event that:

          (1) the Company takes any action which would require an adjustment in the Conversion Price;

          (2) the Company consolidates or enters into a binding share exchange with, merges with or into, or transfers all or substantially all of its property and assets to, another corporation and shareholders of the Company must approve the transaction; or

          (3) there is a dissolution or liquidation of the Company,

the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be, and mail the notice at least 10 days before such date; provided, further, that upon occurrence of an event referred to in clause (1) of this Section 5.10, the Company shall file with the Trustee (and deliver a copy to the Conversion Agent) an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it and promptly mail to Holders a notice of the adjustment. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 5.10; provided, however, that unless and until the Trustee and the Conversion Agent shall have received an Officers’ Certificate setting forth an adjustment of the Conversion Price in connection with the event referred to in clause (1), the Trustee may assume without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has knowledge remains in effect.

     Section 5.11. Effect of Reclassification, Consolidation, Merger, Binding Share Exchange or Sale on Conversion Privilege.

     If any of the following shall occur, namely: (a) any reclassification or change of shares of Common Stock issuable upon conversion of the Securities (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in Section 5.06); (b) any consolidation, merger, binding share exchange or combination to which the Company is a party other than a merger or binding share exchange in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Common Stock; or (c) any sale, assignment, conveyance, transfer, lease or other disposition as an entirety or substantially as an entirety of the property and assets of the Company, directly or indirectly, to any person, then the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification, change, combination, consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to convert such Security into the kind and amount of shares of stock and other securities and property (including Cash) receivable upon such reclassification, change, combination, consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition by a holder of the number of shares of Common Stock deliverable upon conversion of such Security immediately prior to such reclassification, change, combination, consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition (the “Reference Property”). For purposes of the foregoing, if holders of the Common Stock receive or have the right to receive more than one form of consideration in connection with such reclassification, change, combination, consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition, then the Reference Property shall be based on weighted average of elections as to consideration made by holders of the Common Stock (such as pro rata reductions made to any portion of consideration payable). If the Common Stock is replaced by Reference Property, thereafter all references to Common Stock in this Indenture shall be references to such Reference Property, except as the context otherwise requires. The determination of the Reference Property shall apply to all of the Securities and the Company shall notify the Trustee of the composition

of the Reference Property promptly after it is determined. Such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in this Article 5. If, in the case of any such consolidation, merger, binding share exchange, combination, sale, assignment, conveyance, transfer, lease or other disposition, the stock or other securities and property (including Cash) receivable thereupon by a holder of Common Stock include shares of stock or other securities and property of a person other than the successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, binding share exchange, combination, sale, assignment, conveyance, transfer, lease or other disposition, then such supplemental indenture shall also be executed by such other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The provisions of this Section 5.11 shall similarly apply to successive reclassifications, changes, combinations, consolidations, mergers, binding share exchanges, sales, assignments, conveyances, transfers, leases and other dispositions. The Trustee has no duty to determine whether a supplemental indenture under this Section 5.11 need be entered into.

     In the event the Company shall execute a supplemental indenture pursuant to this Section 5.11, the Company shall promptly file with the Trustee (x) an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities upon the conversion of their Securities after any such reclassification, change, combination, consolidation, merger, binding share exchange, sale, assignment, conveyance, transfer, lease or other disposition, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and (y) an Opinion of Counsel that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders.

     Section 5.12. Disclaimer.

     Nether the Trustee nor any Conversion Agent (other than the Company or an Affiliate of the Company) shall have any duty to determine when an adjustment under this Article 5 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers’ Certificate, including the Officers’ Certificate with respect thereto, which the Company is obligated to file with the Trustee (and to deliver a copy thereof to the Conversion Agent) pursuant to Section 5.10. Neither the Trustee nor any Conversion Agent (other than the Company or an Affiliate of the Company) makes any representation as to the validity or value of any securities or assets issued upon conversion of Securities, and neither shall be responsible for the Company’s failure to comply with any provisions of this Article 5.

     The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 5.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 5.11.

     Section 5.13. Limitation on Adjustments.

     (a) The Company shall not take any action that would result in an adjustment pursuant to the foregoing provisions in this Article 5 without complying with the shareholder approval rules of the NASDAQ Stock Market (including NASDAQ Market Rule 5635), or any similar rules of any other stock exchange on which the Common Stock may be listed, if applicable.

     (b) The Company shall not take any action that would result in an adjustment pursuant to the foregoing provisions in this Article 5 if that adjustment would reduce the Conversion Price below the then par value of the shares of Common Stock issuable upon conversion of the Securities.

ARTICLE 6

[Reserved]

ARTICLE 7

COVENANTS

     Section 7.01. Payment of Securities.

     The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities and this Indenture. An installment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 11:00 a.m. (New York City time) on that date money, deposited by the Company or an Affiliate thereof, sufficient to pay such installment. The Company shall (in immediately available funds), to the fullest extent permitted by law, pay interest on overdue principal and overdue installments of interest at the rate borne by the Securities per annum.

     Payment of the principal of and interest on the Securities shall be made at the office or agency of the Company maintained for that purpose in New York, New York (which shall initially be The Bank of New York Mellon), or at the Corporate Trust Office of the Trustee in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided, further, that a Holder holding an aggregate principal amount of the Securities in excess of $1,000,000 shall be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee and the Paying Agent at least 10 Business Days prior to the payment date; provided, further, that all payments made to the Depositary or its nominee shall be made by wire transfer in immediately available funds.

     Section 7.02. SEC Reports.

     So long as any Securities are outstanding, the Company shall (i) file with the SEC within the time periods prescribed by its rules and regulations and (ii) furnish to the Trustee and the Holders of the Securities within 15 days after the date on which the Company would be required to file the same with the SEC pursuant to its rules and regulations (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act), all quarterly and annual financial information required to be contained in Forms 10-Q and 10-K and, with respect to the annual consolidated financial statements only, a report thereon by the Company’s independent auditors.

     Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Company shall not be required to file any report or other information with the SEC if the SEC does not permit such filing, although such reports shall be furnished to the Trustee. Documents filed by the Company with the SEC via the SEC’s EDGAR system (or any successor thereto) will be deemed furnished to the Trustee and the Holders of the Securities as of the time such documents are filed via EDGAR (or such successor). The Trustee is hereby directed, which direction may be changed by the Company at any time, upon a three Business Day prior written notice, to access the EDGAR system for purposes of retrieving the reports so filed. 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.

     Section 7.03. No Resale of Restricted Securities.

     During the period of one year after the last original issuance of the Securities, the Company shall not, and shall not permit any of its Affiliates to, resell any of the Securities that constitute Transfer Restricted Securities that have been reacquired by any of them. The Securities will be issued with a restricted CUSIP number. Until such time as the Company notifies the Trustee to remove the Restricted Security Legend from the Securities, the restricted CUSIP will be the CUSIP number for the Securities. At such time as the Company notifies the Trustee to remove the Restricted Security Legend from the Securities, such Restricted Security Legend will be deemed removed from any Global Securities and an unrestricted CUSIP number for the Securities will be deemed to be the CUSIP number for the Securities.

     Section 7.04. Compliance Certificates.

     The Company shall deliver to the Trustee, within 90 days after the end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2009), an Officers’ Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and covenants on its part contained in this Indenture and stating whether or not the signer knows of any default or Event of Default. If such signer knows of such a default or Event of Default, the Officers’ Certificate shall describe the default or Event of Default and the efforts to remedy the same. For the purposes of this Section 7.04, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture.

     The Company shall deliver to the Trustee, as soon as possible and in any event within thirty days after the Company becomes aware of the occurrence of any Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of such Event of Default or default and the action which the Company proposes to take with respect thereto.

     Section 7.05. Additional Interest Notice.

     In the event that the Company is required to pay Additional Interest to Holders of Securities pursuant to Sections 7.10 or 9.02(b) hereof, the Company shall provide a direction or order in the form of a written notice (“Additional Interest Notice”) to the Trustee (and if the Trustee is not the Paying Agent, the Paying Agent) of the Company’s obligation to pay Additional Interest no later than ten Business Days prior to the proposed payment date set for the payment of Additional Interest, and the Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct the Trustee (or, if the Trustee is not the Paying Agent, the Paying Agent) to make payment to the extent it receives funds from the Company to do so. The Trustee shall not at any time be under any duty or responsibility to any holder of Securities to determine whether Additional Interest is payable, or with respect to the nature, extent, or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of Additional Interest.

     Section 7.06. Rule 144A Information Requirements.

     For so long as any of the Securities or the Common Stock issuable upon the conversion thereof are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it is not subject to and in compliance with Section 13 or 15(d) under the Exchange Act, upon the request of any Holder or beneficial holder of the Securities or any Common Stock issued upon conversion thereof bearing a Restricted Security Legend or Restricted Stock Legend, as the case may be, make available to such Holder or beneficial holder of such Securities or any Common Stock issued upon conversion thereof in connection with any sale thereof and any prospective purchaser of Securities or such Common Stock designated by such Holder or beneficial holder, the information required pursuant to Rule 144A(c)(2) under the Securities Act and it shall take such further action as any Holder or beneficial holder of such Securities or such Common Stock may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Upon the request of any Holder or any beneficial holder of the Securities or such Common Stock, the Company shall deliver to such Holder a written statement as to whether such Holder and prospective purchaser have complied with such requirements.

     Section 7.07. Further Instruments and Acts.

     Upon request of the Trustee, 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 7.08. Maintenance of Corporate Existence.

     Subject to Article 8, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

     Section 7.09. Stay, Extension and Usury Laws.

     The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of, or premium, if any, or interest on, the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it shall not, by resort to any such law, 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 7.10. Additional Interest Payable Upon Failure to Report or to Delegend.

     (a) If at any time during the six months to one-year period following the last original issuance date of the Securities, the Company fails to timely file any document or report that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (other than any Current Report on Form 8-K), as applicable, or the Securities are not otherwise freely tradable by the Holders, other than Holders who are Affiliates of the Company (as a result of restrictions imposed pursuant to U.S. securities law or the terms of this Indenture or the Securities), the Company shall make a one time payment in respect of the Securities in the amount of 0.50% of their principal amount, provided that the Company will have 14 days, in the aggregate, to cure all such missed filings.

excess of $5.0 million is not paid at final maturity (or when otherwise due) or is accelerated, and such indebtedness is not discharged (or such default in payment or acceleration is not cured or rescinded) within 30 days after written notice as provided in this Indenture;

     (h) the Company or any Significant Subsidiary of the Company (or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary) fails to pay one or more final and non-appealable judgments entered by a court or courts of competent jurisdiction, the aggregate uninsured or unbonded portion of which is in excess of $5.0 million, if the judgments are not paid, discharged or stayed within 30 days;

     (k) A default under clause (d) above is not an Event of Default until the Trustee notifies the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, in writing of the default, and the Company does not cure the default within 60 days after receipt of such notice. The notice given

pursuant to this Section 9.01 must specify the default, demand that it be remedied and state that the notice is a “Notice of Default.” When any default under this Section 9.01 is cured, it ceases.

     Section 9.02. Acceleration.

     (a) If an Event of Default (other than an Event of Default specified in clause (i) or (j) of Section 9.01) occurs and is continuing with respect to any Securities, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal to the date of acceleration on the Securities then outstanding (if not then due and payable) to be due and payable upon any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in clause (i) or (j) of Section 9.01 occurs, all unpaid principal of the Securities then outstanding shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration of Securities and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) interest which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 10.07 have been made. No such rescission shall affect any subsequent default or impair any right consequent thereto.

     (b) Notwithstanding anything in the Indenture to the contrary, if the Company so elects, the sole remedy for any failure comply with Section 7.02 hereof shall, for 180 days following the occurrence of such an Event of Default, be limited to the payment of Additional Interest as provided in the following sentence. If the Company fails to comply with Section 7.02 hereof to file periodic or other reports, the Company shall pay Additional Interest to all Holders at a rate per annum equal to 0.50% of the principal amount of the Securities to, but not including, the 181st day thereafter (or, if applicable, the earlier date on which such Event of Default is waived). In no event shall Additional Interest accrue at an annual rate in excess of 0.50%, in the aggregate, pursuant to Section 7.10 hereof and this Section 9.02(b). If the Event of Default is continuing on the 181st day after an Event of Default relating to a failure to comply with Section 7.02 first occurs, the Securities shall be subject to acceleration as provided in Section 9.02(a) hereof. All accrued and unpaid Additional Interest arising under this paragraph, if any, shall be paid in arrears in Cash to Holders of the Securities by the Company on the Interest Payment Date on which interest in respect of the Securities for the same accrual period is paid, to the Holders receiving such interest. The provisions of this Indenture described in this paragraph shall not affect the rights of the Holders in the event of the occurrence of any other Events of Default.

     In order to elect to pay additional interest as the sole remedy during the first 180 days after the occurrence of an Event of Default relating to the failure to comply with Section 7.02 in

accordance with the immediately preceding paragraph, the Company shall notify all Holders and the Trustee and Paying Agent of such election on or before the close of business on the fifth Business Day after the date on which such Event of Default otherwise would occur. Upon a failure by the Company to timely give such notice or pay additional interest, the Securities will be immediately subject to acceleration as otherwise provided in this Section 9.02.

     Section 9.03. Other Remedies.

     If an Event of Default with respect to Securities occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or any interest 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 it does not possess any of the Securities or does not produce any of them 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 to the extent permitted by law.

     Section 9.04. Waiver of Defaults and Events of Default.

     Subject to Section 9.02, 9.07 and 12.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing default or Event of Default and its consequence, except a default or Event of Default in the payment of the principal of or interest on, any Security, a failure by the Company to pay the Cash and deliver the shares of Common Stock owing upon conversion of any Security (including Additional Shares, if any) within the time period required by this Indenture or any default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 12.02, cannot be modified or amended without the consent of the Holder of each Security affected. When a default or Event of Default is waived, it is cured and ceases.

     Section 9.05. Control by Majority.

     The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee or that may involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

     Section 9.06. Limitations on Suits.

     A Holder of a Security may not pursue any remedy with respect to this Indenture or the Securities (except actions for payment of overdue principal, premium, if any, or interest or for the conversion of the Securities pursuant to Article 5) unless:

     (a) the Holder personally gives to the Trustee written notice of a continuing Event of Default;

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

     (c) such Holder or Holders offer to the Trustee 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 the request and the offer of indemnity; and

     (e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding.

     A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder, it being understood that the Trustee does not have an affirmative duty to ascertain whether or not a Holder’s actions or forbearances constitute such prejudicial use.

     Section 9.07. Rights of Holders to Receive Payment and to Convert.

     Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of the principal of and interest on the Security, on or after the respective due dates expressed in the Security and this Indenture, to convert such Security in accordance with Article 5 and 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 without the consent of the Holder.

     Section 9.08. Collection Suit by Trustee.

     If an Event of Default in the payment of principal, premium, if any, or interest specified in clause (a) or (b) of Section 9.01 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 of principal and accrued interest remaining unpaid, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

     Section 9.09. Trustee May File Proofs of Claim.

     The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and

to distribute the same, and any Custodian 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 to the Trustee any amount due to 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 10.07, and to the extent that such payment of the reasonable compensation, expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt, 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 9.10. Priorities.

     If the Trustee collects any money pursuant to this Article 9, it shall pay out the money in the following order:

     First, to the Trustee for amounts due under Section 10.07;

     The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 9.10.

     Section 9.11. 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 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 (whether incurred before trial, at trial or on appeal or in any bankruptcy, arbitration or other administrative proceeding), 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 9.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 9.07 or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding.

     (a) to comply with Section 5.11 and 8.01;

     (b) to cure any ambiguity, or correct any defect or inconsistency; provided that any amendment or supplement to cure any ambiguity or correct any defect or inconsistency in the Indenture or the Securities that is made solely to conform the provisions of the Indenture and the Securities to the descriptions thereof contained in the offering memorandum relating to the Securities dated November 10, 2009, shall be deemed not to adversely affect the rights of any Holder;

     (c) to make any other change that does not adversely affect the rights of any Holder;

     (d) to comply with the provisions of the TIA;

     (e) to add to the covenants of the Company for the equal and ratable benefit of the Holders or to surrender any right, power or option conferred upon the Company;

     (f) to appoint a successor Trustee; or

     (g) to provide for the issuance of Additional Securities as permitted by Section 2.16, which will have terms substantially identical to the other outstanding Securities except as specified in Section 2.16, and which will be treated, together with any other outstanding Securities, as a single issue of securities.

     Section 12.02. With Consent of Holders.

     The Company and the Trustee may amend or supplement the Securities or this Indenture with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding. The Holders of at least a majority in aggregate principal amount of the Securities then outstanding may waive compliance in a particular instance by the Company with any provision of the Securities or this Indenture without notice to any Holder. However, notwithstanding the foregoing but subject to Section 12.04, without the written consent of each Holder affected, an amendment, supplement or waiver, including a waiver pursuant to Section 9.04, may not:

     (a) change the Stated Maturity of, or the date any installment of interest (including any Additional Interest) is due on, any Security;

     (b) reduce the principal amount of or interest (including any Additional Interest) on, any Security;

     (c) reduce the amount of principal payable upon acceleration of the maturity of any Security;

     (d) change the place or currency of payment of principal of or interest (including any Additional Interest) on, any Security;

     (e) impair the right of any Holder to receive payment of principal and of interest on such Holder’s Securities on or after the due date therefore or to institute suit for the enforcement of any payment on, or with respect to, any Security;

     (f) modify the provisions with respect to the purchase right of Holders pursuant to Article 3 upon a Fundamental Change in a manner adverse to the Holders of Securities;

     (g) change the ranking of the Securities;

     (h) modify the provisions of this Indenture with respect to conversion of the Securities in a manner adverse to the Holders of Securities; and

     (i) modify any of the provisions of this Section or Section 9.04, except to increase any such percentage or to provide that certain provisions of this Indenture cannot be modified, amended or waived without the consent of the Holder of each outstanding Security affected thereby.

     It shall not be necessary for the consent of the Holders under this Section 12.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof.

     After an amendment, supplement or waiver under this Section 12.02 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any

defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

     Section 12.03. Compliance with Trust Indenture Act.

     Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as applicable to indentures qualified thereunder at the date of such amendment or supplement.

     Section 12.04. Revocation and Effect of Consents.

     Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective.

     After an amendment, supplement or waiver becomes effective, it shall bind every applicable Holder, unless it makes a change described in any of clauses (a) through (j) of Section 12.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

     Section 12.05. Notation on or Exchange of Securities.

     If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

     Section 12.06. Trustee to Sign Amendments, etc.

     The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article 12 if the amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, in its sole discretion, but need not sign it. In signing or refusing to sign such amendment or supplemental indenture, the Trustee shall be provided with, and, subject to Section 10.01, shall be fully protected in relying upon, an Officers’ Certificate (accompanied by a resolution of the Board of Directors of the Company) and an Opinion of Counsel in accordance with Section 13.04 hereof, each stating that such amendment or supplemental indenture is authorized or permitted by this Indenture. The Company may not sign an amendment or supplement indenture until the Board of Directors approves it.

     Section 12.07. Effect of Supplemental Indentures.

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

     Initially, The Bank of New York Mellon (the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holder.

4. INDENTURE, LIMITATIONS

     This Security is one of a duly authorized issue of Securities of the Company designated as its 4.5% Convertible Senior Notes due 2014 (the “Securities”), issued under an Indenture, dated as of November 16, 2009 (together with any supplemental indentures thereto, the “Indenture”), between the Company and the Trustee. The terms of this Security include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this Security is referred to the Indenture and said Act for a statement of them.

5. PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON A FUNDAMENTAL CHANGE

     At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities held by such Holder on the date of the Company’s choosing that is not less than 20 or more than 35 Business Days after the date on which the Company notifies the Holders of the Securities of the occurrence of the effective time of a Fundamental Change, at a purchase price equal to 100% of the principal amount thereof, together with any accrued and unpaid interest up to, but excluding, the Fundamental Change Purchase Date, payable in Cash. The Holder shall have the right to withdraw any Fundamental Change Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to 5:00 p.m. (New York City time) on the second Scheduled Trading Day next preceding the Fundamental Change Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture.

6. CONVERSION

     A Holder of a Security may convert the principal amount of such Security (or any portion thereof equal to $1,000 or any integral multiple of $1,000 in excess thereof) into Common Stock at any time prior to the close of business on the second scheduled Trading Date immediately preceding the maturity date pursuant to Section 5.01 of the Indenture.

     The initial Conversion Price is $10.348 per share, and the initial Conversion Rate is approximately 96.637 shares of Common Stock, in each case subject to adjustment under certain circumstances as provided in the Indenture. Upon conversion, the Company shall deliver to holders in respect of each $1,000 principal amount of Securities being converted a number of shares of Common Stock equal to the applicable Conversion Rate, together with a Cash payment in lieu of any fractional share of Common Stock issuable upon conversion based on the Closing Sale Price of Common Stock on the relevant Conversion Date.

     A Security in respect of which a Holder had delivered a Fundamental Change Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if the Fundamental Change Purchase Notice is withdrawn in accordance with the terms of the Indenture.

7. DENOMINATIONS, TRANSFER, EXCHANGE

     The Securities are in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture.

8.

PERSONS DEEMED OWNERS

     The Holder of a Security may be treated as the owner of it for all purposes.

9. UNCLAIMED MONEY

     If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the Company at its written request, subject to applicable unclaimed property law. After any such payment, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

10. AMENDMENT, SUPPLEMENT AND WAIVER

     Subject to the exceptions set forth in the Indenture, the Securities and the Indenture may be amended or supplemented with the written consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and an existing default or Event of Default with respect to the Securities and its consequence or compliance with any provision of the Securities or the Indenture may be waived in a particular instance with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or the consent of any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, correct any defect or inconsistency or make any other change that does not adversely affect the rights of any Holder.

11. SUCCESSOR ENTITY

     When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor corporation (except in the circumstances specified in the Indenture) shall be released from those obligations.

12. CALCULATIONS IN RESPECT OF SECURITIES

     Except to the extent provided therein, the Company will be responsible for making all calculations called for under the Indenture and the Securities. These calculations include, but are not limited to, determinations of the Closing Sale Price of the Common Stock, adjustments to the Conversion Price, any accrued interest payable on the Securities, the Conversion Price and the Conversion Rate. The Company will make these calculations in good faith and, absent manifest error, the calculations will be final and binding on Holders of the Securities. The Company will provide to each of the Trustee and the Conversion Agent a schedule of its calculations, and the Trustee and the Conversion Agent are entitled to rely conclusively upon the accuracy of such calculations without independent verification. The Trustee will forward the Company’s calculations to any Holder of the Securities upon the request of such Holder.

13. DEFAULTS AND REMEDIES

     Under the Indenture, an Event of Default with respect to the Securities includes: (i) default in the payment of any principal of any Security when the same becomes due and payable; (ii) defaults in the payment of Cash and delivery of shares of Common Stock owing

upon conversion of any Security (including any Additional Shares), when the same becomes due and payable; (iii) default for 30 days in the payment of interest (including any Additional Interest) when the same becomes due and payable; (iv) failure by the Company for 60 days after notice to it to comply with any of its other agreements contained in the Securities or in the Indenture with respect to the Securities (other than a default set forth in clauses (1) through (3) above); (v) default in payment of the purchase price of any Security when the same becomes due and payable; (vi) failure to provide a Fundamental Change Purchase Notice when required; (vii) any indebtedness for money borrowed of the Company or a Significant Subsidiary in an outstanding principal amount, individually or in the aggregate, in excess of $5.0 million is not paid at stated maturity (or when otherwise due) or is accelerated and such indebtedness is not discharged (or such default in payment or acceleration is not cured or rescinded) within 30 days after written notice as provided in the Indenture; (viii) the Company or a Significant Subsidiary fails to pay one or more final and non-appealable judgments entered by a court or courts of competent jurisdiction, the aggregate uninsured or unbonded portion of which is in excess of $5.0 million, if the judgments are not paid, discharged or stayed within 30 days; and (xi) certain events of bankruptcy, insolvency or reorganization of the Company or any Significant Subsidiary. If an Event of Default with respect to the Securities (other than as a result of certain events of bankruptcy, insolvency or reorganization specified in the Indenture) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may declare all unpaid principal to the date of acceleration on the Securities then outstanding to be due and payable immediately, all as and to the extent, and subject to the exceptions, provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization specified in the Indenture, all unpaid principal of the Securities then outstanding shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest, including the failure to make Cash payments and deliver shares of Common Stock due upon conversion) if it determines that withholding notice is in their interests.

14. TRUSTEE DEALINGS WITH THE COMPANY

     The Bank of New York Mellon, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee.

15. NO RECOURSE AGAINST OTHERS

Security by accepting this Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security.
