               (ii) Any such shares of Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock which shall not bear the Restricted Stock Legend.

          (h) The Company shall not permit any Note or share of Common Stock issued upon the conversion or exchange of a Note that is purchased or owned by the Company or any Affiliate thereof to 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 Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144). If the legend is removed from the face of a Note and the Note is subsequently held by the Company or an Affiliate of the Company, the legend shall be reinstated.

Immediately upon receipt of such notice by the Trustee the Restricted Notes Legend will be deemed removed from each of the Global Notes specified in such notice and the restricted CUSIP number will be deemed removed from each of such Global Notes and deemed replaced with an unrestricted CUSIP number; and

               (ii) providing the Depositary an instruction letter for the Depositary’s mandatory exchange process (or any successor notice, form or action required pursuant to the Applicable Procedures) to the extent required.

Such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-Registrar from any loss that any of them may suffer if a Note is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Note.

          Upon the issuance of any new Notes 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 expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Note issued pursuant to this Section 2.07 in exchange for any mutilated Note, or in lieu of any destroyed, lost or stolen Note, shall constitute an original additional contractual obligation of the Company and any other obligor upon the Notes, whether or not the mutilated, destroyed, lost or stolen Note 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 Notes duly issued hereunder.

          Section 2.08 Outstanding Notes. Notes outstanding at any time are all Notes authenticated and delivered under this Indenture except for those cancelled by the Trustee, those

delivered to the Trustee for cancellation and those described in this Section 2.08 as not outstanding. A Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; provided, however, that in determining whether the Holders of the requisite principal amount of Notes have given or concurred in any request, demand, authorization, direction, notice, consent, waiver or other action hereunder, Notes owned by the Company or any obligor upon the Notes or any Affiliate of the Company or such other obligor shall be disregarded and deemed not to be outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such determination as to the presence of a quorum or upon any such request, demand, authorization, direction, notice, consent or waiver, only Notes which a Responsible Officer has been notified in writing to be so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding if the pledgee is not the Company or any other obligor upon the Notes or any Affiliate of the Company or such other obligor, and the Trustee shall be protected in relying upon an Officer’s Certificate to such effect. Subject to the foregoing, only Notes outstanding at the time of such determination shall be considered in any such determination (including, without limitation, determinations pursuant to Article 6 and Article 9).

          If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a bona fide purchaser; provided that in no event shall both the replaced Note and the new Note issued under Section 2.07 be deemed to be outstanding at the same time..

          If the Paying Agent holds, in accordance with this Indenture, on the Maturity Date, money or securities sufficient to pay Notes payable on such date, then immediately after the Maturity Date, such Notes shall cease to be outstanding and interest (including Additional Interest), if any, on such Notes shall cease to accrue, whether or not book-entry transfer of the Notes is made or whether or not the Notes are delivered to the Paying Agent, and such Notes shall cease to be convertible.

          If a Note is converted in accordance with Article 10 and required to be cancelled pursuant to Section 2.10, then from and after the time of conversion on the Conversion Date, such Note shall cease to be outstanding and interest (including Additional Interest), if any, shall cease to accrue on such Note.

     Section 2.09 Temporary Notes. Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes (“Temporary Notes”). Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for Temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes and deliver them in exchange for Temporary Notes.

     Section 2.10 Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar, the Conversion Agent and the Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange, conversion or payment. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, conversion payment or cancellation and shall dispose of such cancelled Notes in its customary manner. The Company may not issue new Notes to replace Notes it has

redeemed, paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10.

     Section 2.11 Persons Deemed Owners. Prior to due presentment of a Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Note is registered in the Register as the owner of such Note for the purpose of receiving payment of principal, interest (including any Additional Interest) or the Fundamental Change Repurchase Price or the Redemption Price, for the purpose of conversion and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Trustee and their respective agents shall be affected by notice to the contrary.

     Section 2.12 Transfer of Notes.  Notwithstanding any other provisions of this Indenture or the Notes, (A) transfers of a Global Note, in whole or in part, shall be made only in accordance with Section 2.06 and Section 2.12(a)(i); (B) transfers of a beneficial interest in a Global Note for a Certificated Note shall comply with Section 2.06 and Section 2.12(a)(ii) below, and (C) transfers of a Certificated Note shall comply with Section 2.06 and Section 2.12(a)(iii) and (iv) below. Any such transfer shall comply with the Applicable Procedures to the extent so required.

          (a) Provisions relating to transfers and exchanges:

               (i) Transfer of Global Note. A Global Note 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 this clause (i) shall not prohibit any transfer of a Note that is issued in exchange for a Global Note but is not itself a Global Note. No transfer of a Note to any Person shall be effective under this Indenture or the Notes unless and until such Note has been registered in the name of such Person. Nothing in this Section 2.12(a)(i) shall prohibit or render ineffective any transfer of a beneficial interest in a Global Note effected in accordance with the other provisions of this Section 2.12(a).

               (ii) Restrictions on Transfer of a Beneficial Interest in a Global Note for a Certificated Note. A beneficial interest in a Global Note may not be exchanged for a Certificated Note except:

                     (A) Certificated Notes shall be issued to all owners of beneficial interests in a Global Note in exchange for such interests if:

                         (1) DTC notifies the Company that it is unwilling or unable to continue as Depositary for such Global Note and a successor Depositary is not appointed by the Company within 90 calendar days of such notice; or

                         (2) the Company, at any time, in its sole discretion, executes and delivers to the Trustee and the Registrar an Officer’s Certificate stating that the entire Global Note shall be so exchangeable.

          In connection with the exchange of an entire Global Note for Certificated Notes pursuant to this clause (ii), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and upon Company Order the Trustee shall

authenticate and deliver, to each beneficial owner identified by DTC in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Certificated Notes of authorized denominations.

                    (B) The owner of a beneficial interest in a Global Note will be entitled to receive a Certificated Note in exchange for such interest if an Event of Default has occurred and is continuing.

     Upon receipt by the Registrar of instructions from the Holder of a Global Note directing the Registrar to (x) issue one or more Certificated Notes in the amounts specified to the owner of a beneficial interest in such Global Note and (y) debit or cause to be debited an equivalent amount of beneficial interest in such Global Note, subject to the Applicable Procedures:

                         (1) the Registrar shall notify the Company and the Trustee of such instructions, identifying the owner and amount of such beneficial interest in such Global Note;

                         (2) the Company shall promptly execute, and upon Company Order the Trustee shall authenticate and deliver, to such beneficial owner Certificated Note(s) in an equivalent amount to such beneficial interest in such Global Note; and

                         (3) the Registrar shall decrease such Global Note by such amount in accordance with the foregoing.

               (iii) Transfer and Exchange of Certificated Notes. When Certificated Notes are presented to the Registrar with a request: (x) to register the transfer of such Certificated Notes; or (y) to exchange such Certificated Notes for an equal principal amount of Certificated Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Notes surrendered for transfer or exchange:

                    (A) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing; and

                    (B) so long as such Notes are “restricted securities” (as defined under Rule 144), such Notes are being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (1), (2) or (3) below, and are accompanied by the following additional information and documents, as applicable:

                         (1) if such Certificated Notes are being delivered to the Registrar by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect; or

                         (2) if such Certificated Notes are being transferred to the Company, a certification to that effect; or

                         (3) if such Certificated Notes are being transferred pursuant to an exemption from registration, (i) a certification to that effect (in the form attached hereto as Exhibit B, if applicable) and (ii) if the Company so requests, an Opinion of Counsel in form and substance reasonably satisfactory to it or other evidence in form and substance reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend thereon.

               (iv) Restrictions on Transfer of a Certificated Note for a Beneficial Interest in a Global Note. A Certificated Note may not be exchanged for a beneficial interest in a Global Note except upon satisfaction of the requirements set forth below.

     Upon receipt by the Trustee of a Certificated Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

                    (A) so long as the Notes are Restricted Notes, certification, in the form attached hereto as Exhibit B, that such Certificated Note is being transferred to a QIB in accordance with Rule 144A; and

                    (B) written instructions directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Note to reflect an increase in the aggregate principal amount of the Notes represented by the Global Note, such instructions to contain information regarding the Depositary account to be credited with such increase, then the Trustee shall cancel such Certificated Note and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of Notes represented by the Global Note to be increased by the aggregate principal amount of the Certificated Note to be exchanged, and shall credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Global Note equal to the principal amount of the Certificated Note so cancelled. If no Global Notes are then outstanding, the Company shall issue and the Trustee shall authenticate, upon written order of the Company in the form of a Company Order, a new Global Note in the appropriate principal amount.

          (b) Subject to the succeeding Section 2.12(c), every Note shall be subject to the restrictions on transfer provided in Section 2.06(f), including the delivery of an Opinion of Counsel, if so required. Whenever any Restricted Note is presented or surrendered for registration of transfer or for exchange for a Note registered in a name other than that of the Holder, such Note must be accompanied by a certificate in substantially the form attached hereto as Exhibit B, dated the date of such surrender and signed by the Holder of such Note, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such registration of transfer or exchange any Note not so accompanied by a properly completed certificate.

          (c) The restrictions imposed by Sections 2.06(f) upon the transferability of any Note shall cease and terminate when such Note has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144 by a Person other than an Affiliate or a former Affiliate. Any Note as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of

such Note for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by an opinion of counsel having substantial experience in practice under the Securities Act and otherwise reasonably acceptable in form and substance to the Company, addressed to the Company, to the effect that the transfer of such Note has been made in compliance with Rule 144), be exchanged for a new Note, of like tenor and aggregate principal amount, which shall not bear the legends required by Section 2.01(e). The Company shall inform the Trustee in writing upon the occurrence of the Free Trade Date and promptly after a registration statement with respect to the Notes or any shares of Common Stock issued upon conversion of the Notes has been declared effective under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned Opinion of Counsel or registration statement.

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

               (i) Notwithstanding any other provisions of this Indenture or the Notes, a Global Note shall not be exchanged in whole or in part for a Note registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Note may be exchanged for Notes registered in the name 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 Note 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 calendar days or (B) an Event of Default has occurred and is continuing with respect to the Notes. Any Global Note exchanged pursuant to clause (A) above shall be so exchanged in whole and not in part, and any Global Note exchanged pursuant to clause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.

               (ii) Notes issued in exchange for a Global Note 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 Note 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 Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Note to be exchanged in part, either such Global Note 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 Note, 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 Note issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

               (iii) Subject to the provisions of Section 2.12(e), the 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 Notes.

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

               (v) The Trustee shall have no responsibility for any actions taken or not taken by the Depositary.

          (e) Neither any members of, or participants in, the Depositary (collectively, the “Agent Members”) nor any other Persons on whose behalf any Agent Member may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, or under any such Global Note, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Note for all purposes whatsoever. The Trustee shall have no responsibility or obligation to any Agent Members or any other Person on whose behalf Agent Members may act with respect to (i) any ownership interests in the Global Note, (ii) the accuracy of the records of the Depositary or its nominee, (iii) any notice required hereunder or (iv) any payments under or with respect to the Global Note. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Note. The registered Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Indenture or the Notes.

          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 Note (including any transfers between or among Agent Members or beneficial owners of interests in any Global Note) 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 2.13 CUSIP and ISIN Numbers.

          (a) The Company, in issuing the Notes, will use restricted CUSIP and ISIN numbers for such Notes (if then generally in use) until such time as the Restricted Notes Legend is removed pursuant to Section 2.06(i). At such time as the Restricted Notes Legend is removed from such Notes pursuant to Section 2.06(i), the Company will use an unrestricted CUSIP

number for such Note, but only with respect to the Notes from which the Restricted Notes Legend is so removed. The Trustee shall use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders; provided, however, that neither the Company nor the Trustee shall have any responsibility for any defect in the CUSIP or ISIN number that appears on any Note, check, advice of payment or redemption notice, and any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing in the event of any change in the CUSIP or ISIN numbers.

          (b) Except as otherwise provided in this Section 2.13(b), the Company, upon issuing shares of Common Stock upon conversion of Notes, will use a restricted CUSIP number for such shares of Common Stock. Until such time as the Restricted Stock Legend is removed pursuant to Section 2.06(g) or otherwise from such shares of Common Stock, the applicable restricted CUSIP number will be the CUSIP number for such shares of Common Stock. At such time as the Restrictive Stock Legend is removed from such shares of Common Stock pursuant to Section 2.06(g) or otherwise, an unrestricted CUSIP number for such shares of Common Stock will be deemed to be the CUSIP number for such shares of Common Stock, but only with respect to the shares of Common Stock from which the Restrictive Stock Legend is so removed.

          The Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof in accordance with the provisions of Section 3.02(c).

          Any Note that is to be repurchased only in part shall be surrendered to the Trustee (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Note without service charge, a new Note or Notes, containing identical terms and conditions, each in an authorized denomination in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Note so surrendered.

          (b) After the occurrence of a Fundamental Change, but on or before the 10th calendar day following the Effective Date of such Fundamental Change, the Company shall provide to all Holders and the Trustee and Paying Agent a notice (the “Fundamental Change Repurchase Right Notice”), in the manner provided for in Section 13.01, of the occurrence of such Fundamental Change and of the repurchase right, if any, at the option of the Holders, arising as a result thereof.

          Each Fundamental Change Repurchase Right Notice shall specify:

               (i) the events causing the Fundamental Change and whether such Fundamental Change also constitutes a Make-Whole Fundamental Change;

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

          No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.02.

          (c) A Fundamental Change Repurchase Notice may be withdrawn in whole or in part by means of a written notice of withdrawal delivered to the Paying Agent at any time prior to the Fundamental Change Expiration Time, specifying:

               (i) if certificated Notes have been issued, the certificate numbers of the withdrawn Notes,

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

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

provided, however, that if the Notes are not in certificated form, such notice must comply with any Applicable Procedures.

          (d) The Company shall deposit with the Paying Agent, in accordance with Section 4.01, an amount of money sufficient to repurchase on the Fundamental Change Repurchase Date all of the Notes to be repurchased on such date at the Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Paying Agent, and subject to extension to comply with applicable law, payment for Notes surrendered for repurchase (and not withdrawn) prior to the Fundamental Change Expiration Time shall be made promptly after the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions to the payment of the Fundamental Change Repurchase Price in this Section 3.02), and (y) the time of book-entry transfer or the delivery of such Note to the Paying Agent by the Holder thereof in the manner required by this Section 3.02 by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Fundamental Change Repurchase Price.

          (e) Subject to a Holder’s right to receive interest on the related Interest Payment Date where the Fundamental Change Repurchase Date falls between a Regular Record Date and the Interest Payment Date to which it relates, if the Paying Agent holds money sufficient to repurchase on the Fundamental Change Repurchase Date all of the Notes or portions thereof that are to be purchased as of the Business Day following the Fundamental Change Repurchase Date, then on and after the Fundamental Change Repurchase Date (i) such Notes shall cease to be outstanding and interest shall cease to accrue on such Notes, in either case, whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Paying Agent and (ii) all other rights of the Holders of such Notes shall terminate other than the right to receive the Fundamental Change Repurchase Price and previously accrued and unpaid interest, if any.

          (f) No Notes may be repurchased on any date at the option of Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the applicable Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a default by the Company in the payment of the applicable Fundamental Change Repurchase Price with respect to such Notes).

          (g) In connection with any repurchase offer pursuant to a Fundamental Change Repurchase Notice, the Company shall, if required: (i) comply with the provisions of Rule 13e-4 under the Exchange Act, Rule 14e-1 under the Exchange Act and any other tender offer rules under the Exchange Act that may then be applicable; (ii) file a Schedule TO (or any successor schedule, form or report) to the extent required or any other required schedule under the Exchange Act; and (iii) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes.

COVENANTS

     Section 4.01 Payment of Notes. The Company shall promptly make all payments in respect of the Notes on the dates and in the manner provided in the Notes or pursuant to this Indenture. Any amounts of cash and/or shares of Common Stock to be given to the Trustee, the Paying Agent or the Conversion Agent shall be deposited by the Company with the Trustee, the Paying Agent or the Conversion Agent by the Open of Business on the required date. The Company may, at its option, make payments in respect of the Notes by check mailed to a Holder’s registered address (or, if requested by a Holder of more than $2,000,000 principal amount of the Notes, by wire transfer in immediately available funds to that Holder’s account within the United States designated by such Holder in written notice to the Registrar by the Close of Business on the Regular Record Date or other record date relating to such payment, which notice shall remain effective until withdrawn by such Holder in a subsequent written notice to the Registrar) or, with respect to Global Notes, by wire transfer in immediately available funds. The Company shall make any required interest (including any Additional Interest) payments to the Person in whose name each Note is registered at the Close of Business on the Regular Record Date for such interest payment.

     The Company shall, on or before each due date of the principal (including the Redemption Price, if applicable, and the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest, including Additional Interest, if any, on, the Notes or each date when delivery of cash and, if applicable, shares of Common Stock are due upon conversion of a Note, as applicable, deposit with the Paying Agent or the Conversion Agent, as applicable, a sum sufficient to pay such principal (including the Redemption Price, if applicable, or the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, including Additional Interest, if any, and such settlement obligations upon conversion, and (unless such Paying Agent or such Conversion Agent, as applicable, is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the applicable due date, such deposit must be received by the Paying Agent no later than 10:00 a.m., New York City time, on such date.

     If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price, if applicable, and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest, including Additional Interest, if any, on, the Notes, set aside, segregate and hold in trust as provided in Section 2.04 for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price, if applicable, and the Fundamental Change Repurchase Price, if applicable)

          The principal, accrued and unpaid interest (including Additional Interest), if any, the Fundamental Change Repurchase Price, if applicable, or the Redemption Price, if applicable, of the Notes being repaid, repurchased or redeemed, if applicable, shall be considered paid on the applicable date due if on such date the Trustee or the Paying Agent holds, in accordance with the foregoing provisions of this Section 4.01, cash sufficient to pay all such amounts then due.

          Nothing herein shall preclude the withholding of any taxes required by law to be withheld or deducted.

     Section 4.02 SEC and Other Reports. The Company shall file any documents or reports that it is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (other than documents subject to confidential treatment and correspondence with the SEC) with the Trustee within 15 calendar days after the same are required to be filed with the SEC (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Documents filed by the Company via the EDGAR system will be deemed to be filed with the Trustee as of the time such documents are filed via the EDGAR system, provided, however, that the Trustee shall have no responsibility whatsoever to determine whether such filing via the EDGAR system has occurred.

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

     Section 4.03 Additional Interest.

          (a) If, at any time during the six-month period beginning on, and including, the date which is six months after the Issue Date and ending on the Free Trade Date, the Company fails to timely file any periodic report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to any extensions under Rule 12b-25 under the Exchange Act and other than current reports on Form 8-K), the Company shall pay Additional Interest at a rate of 0.50% per annum on the Notes, accruing from the due date of the first missed filing that gives rise to such obligation and continuing through the earlier of (i) the Free Trade Date and (ii) the date all such missed filings have been made.

          (b) In addition, if the Notes or the shares of Common Stock issuable upon conversion of the Notes do not become Freely Tradable by no later than the date 15 calendar days following the Free Trade Date (or the next succeeding Business Day if such 15^th day is not a Business Day), the Company will pay Additional Interest on the Notes at a rate of 0.50% per annum from,

and including, the Free Trade Date and until the date on which the Notes and the shares of Common Stock issuable upon conversion of the Notes become Freely Tradable.

          (c) Any Additional Interest payable pursuant to this Section 4.03 will be in addition to any Additional Interest payable pursuant to Section 6.02(b). Whenever Additional Interest is accruing on a Regular Record Date, the Company will pay all accrued and unpaid Additional Interest to the Holders of record on such Regular Record Date on the corresponding Interest Payment Date. If Additional Interest is not accruing on a Regular Record Date, but has accrued since the immediately preceding Regular Record Date, the Company shall pay any accrued and unpaid Additional Interest on the Interest Payment Date corresponding to the later Regular Record Date to Holders of record on such later Regular Record Date.

          In the event that the Company is required to pay Additional Interest to Holders, the Company shall provide a direction or order in the form of a written notice to the Paying Agent of the Company’s obligation to pay such Additional Interest no later than three Business Days prior to the date on which any such Additional Interest is scheduled to be paid. Such notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date and direct 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 to determine whether the Additional Interest is payable, or with respect to the nature, extent or calculation of the amount of the Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

          Notwithstanding the foregoing in this Section 4.03, in no event will the Company be required to pay Additional Interest on any date on which:

          (i)(1) the Company has filed a shelf registration statement for the resale of the Notes and any shares of Common Stock issuable upon conversion of the Notes, (2) such shelf registration statement is effective and usable by Holders identified therein as selling securityholders for the resale of the Notes and any shares of Common Stock issued upon conversion of the Notes, (3) the Holders may register the resale of their Notes under such shelf registration statement on terms customary for the resale of convertible securities offered in reliance on Rule 144A, and (4) the Notes and/or shares of Common Stock sold pursuant to such shelf registration statement become Freely Tradable as a result of such sale; or

          (ii) the Company has complied with the requirements set forth in the foregoing clause (i) for a period of two years.

          The accrual of Additional Interest will be the exclusive remedy available to Holders for the failure of the Notes to become Freely Tradable on the Free Trade Date.

     Section 4.04 Compliance Certificate. The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year (beginning with the fiscal year ending December 31, 2011) of the Company an Officer’s Certificate, stating whether or not to the knowledge of the signers thereof, there has occurred a Default during the previous fiscal year.

     Section 4.05 Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

     Section 4.06 Maintenance of Office or Agency. The Company will maintain in New York, New York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion Agent where Notes may be presented or surrendered for payment, where Notes may be surrendered for registration of transfer, exchange, repurchase, redemption or conversion and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The office of Wells Fargo Bank, National Association, at 45 Broadway, 14^th Floor, New York, NY 10006, Attention: Corporate Trust Services—Administrator for BroadSoft, Inc. 1.50% Convertible Senior Notes due 2018, shall initially be such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the Corporate Trust Office of the Trustee). If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 13.01.

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

     Section 4.07 Delivery of Certain Information. At any time when the Company is not subject to Sections 13 or 15(d) of the Exchange Act and the Company no longer files such reports with the SEC, the Company shall furnish to Holders, beneficial owners and prospective purchasers of the Notes or shares of Common Stock issuable upon conversion of the Notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

     Section 4.08 Par Value Limitation. The Company shall not take any action that, after giving effect to any adjustment pursuant to Section 10.04, would result in the issuance of shares of Common Stock for less than the par value of such shares of Common Stock.

     Section 4.09 Statement by Officers as to Default. The Company shall deliver to the Trustee, within 30 calendar days after becoming aware of the occurrence of any Default or any Event of Default under this Indenture, an Officer’s Certificate (which Officer’s Certificate shall not be required to include such statements included in Section 13.03) specifying with particularity such Default or Event of Default and further stating what action the Company has taken, is taking or proposes to take with respect thereto.

               (i) either (a) the Company is the surviving Person (the “Successor Person”) or (b) if the Company is not the Successor Person, then either the Successor Person formed by such consolidation or with or into which the Company is merged or the Person to which the Company’s properties and assets are so transferred shall be a Person organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia; provided, however, that the Successor Person shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all of the obligations of the Company under the Notes and this Indenture;

          (g) default by the Company or any Subsidiary of the Company with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any debt for money borrowed in excess of $20.0 million in the aggregate of the Company and/or any such Subsidiary, whether such debt now exists or shall hereafter be created, which default results:

               (i) in such debt becoming or being declared due and payable, and such debt shall not have been discharged in full or such declaration rescinded or annulled within 30 calendar days or

          (h) a final judgment for the payment of $20.0 million or more (excluding any amounts covered by insurance) rendered against the Company or any Subsidiary of the Company, which judgment is not discharged, bonded, paid, waived or stayed within 60 calendar days after (i) the date on which the right to appeal thereof has expired if no such appeal has commenced, or (ii) the date on which all rights to appeal have been extinguished;

          (i) the Company shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to the Company or any of its Significant Subsidiaries or its debts under any bankruptcy, insolvency or other similar law now or hereafter

          (j) an involuntary case or other proceeding shall be commenced against the Company or any of its Significant Subsidiaries seeking liquidation, reorganization or other relief with respect to the Company or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the Company or any of its Significant Subsidiaries or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of 90 consecutive calendar days.

     Section 6.02 Acceleration; Rescission and Annulment.

          (a) If an Event of Default (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company) occurs and is continuing, then in every such case (except as provided in the immediately following paragraph) the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of and accrued and unpaid interest on all such Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal and all accrued interest thereon (including any Additional Interest) shall become immediately due and payable. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company occurs, the principal of, and accrued interest (including any Additional Interest) on, all of the Notes shall become immediately due and payable without any declaration or other Act of the Holders or any act on the part of the Trustee.

          (b) Notwithstanding the foregoing, to the extent the Company’s elects, the sole remedy for an Event of Default specified in Section 6.01(f) relating to failure by the Company to comply with its obligations pursuant to Section 4.02 or Section 4.07 (the “Company’s Filing Obligations”), shall after the occurrence of such Event of Default (which will be the 61st calendar day after written notice is provided to the Company of the Default pursuant to Section 6.01(f)), consist exclusively of the right to receive Additional Interest at a rate equal to (i) 0.25% per annum of the principal amount of the outstanding Notes for each day during the 180-day period on which such Event of Default is continuing, beginning on, and including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum of the principal amount of the outstanding Notes for each day during the 185-day period beginning on, and including, the 181^st calendar day on which such an Event of Default is continuing. On the 366th calendar day immediately following such Event of Default (if the Event of Default relating to the Company’s Filing Obligations is not cured or waived prior to such 366th day), the Notes will be subject to acceleration as provided in Section 6.02(a). This provision will not affect the rights of Holders in the event of the occurrence of any other Event of Default. Such Additional Interest, if so elected by the Company pursuant to this paragraph, shall be payable in the same manner and on the same dates as stated interest payable on the Notes. The Company may make such election by notifying, in the manner provided for in Section 13.01, the Trustee, the Paying Agent and the

Holders of such election prior to the beginning of such 365-day period. Upon the Company’s failure to timely give such notice, the Notes will be immediately subject to acceleration as provided herein. If Additional Interest has been paid by the Company directly to the Persons entitled to such Additional Interest, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment.

          In the event the Company does not elect to pay such Additional Interest or the Company elects to make such payment but does not pay such Additional Interest when due, the Notes will be immediately subject to acceleration as provided in Section 6.02(a).

          Any Additional Interest payable pursuant to this Section 6.02(b) will be in addition to any Additional Interest payable pursuant to Section 4.03.

          (c) This Section 6.02, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all Events of Defaults with respect to such Notes, other than the nonpayment of principal of and accrued and unpaid interest on, or failure to deliver amounts due upon conversion of, such Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.04, then and in every such case the Holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. No rescission or annulment referred to above shall affect any subsequent Default or impair any right consequent thereon.

     Section 6.03 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, accrued and unpaid interest (including Additional Interest), if any, or payment of the Fundamental Change Repurchase Price or the Redemption Price on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

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

     Section 6.04 Waiver of Past Defaults. The Holders of a majority in aggregate principal amount of the outstanding Notes may waive, by written notice to the Trustee and without notice to any other Holder, an existing or past default and its consequences except (a) an Event of Default described in Sections 6.01(a) or 6.01(b) (other than any nonpayment of principal of the Notes that has become due solely by reason of a declaration of acceleration, to the extent that

such declaration of acceleration is duly rescinded in accordance with this Indenture) (b) a default in respect of a provision that, under Section 9.02, cannot be amended without the consent of each Holder or (c) an Event of Default described in Section 6.01(c). When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other default or impair any consequent right.

     Section 6.05 Control by Majority. The Holders of a majority in aggregate principal amount of outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01 and Section 7.02, that the Trustee determines is unduly prejudicial to the rights of other Holders or would potentially involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

     Section 6.06 Limitation on Suits. A Holder may pursue any remedy with respect to this Indenture or the Notes only if:

          (a) such Holder shall have previously given to the Trustee notice that an Event of Default is continuing;

          (b) the Holders of at least 25% in aggregate principal amount of the outstanding Notes have requested the Trustee pursue the remedy;

          (c) such Holders shall have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

          (d) the Trustee has not complied with such request within 60 calendar days after the receipt of the request and the offer of security or indemnity; and

          (e) the Holders of at least a majority in aggregate principal amount of the outstanding Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60 calendar day period.

          A Holder may not use this Indenture to prejudice the rights of any other Holder or to obtain a preference or priority over any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

     Section 6.07 Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to bring suit for the enforcement of payment of principal, accrued and unpaid interest (including Additional Interest), if any, the Fundamental Change Repurchase Price, if applicable, or the Redemption Price, if applicable, on or after the respective due dates expressed in such Holder’s Notes, and to convert the Notes in accordance with Article 10, shall not be impaired or affected without the consent of such Holder and shall not be subject to the requirements of Section 6.06.

     Section 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest (including any Additional Interest) to the extent lawful) and the amounts provided for in Section 7.06.

     Section 6.09 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make 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 it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel and any other amounts due the Trustee under Section 7.06.

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

FIRST: to the Trustee for amounts due under Section 7.06;

SECOND: to Holders for amounts due and unpaid on the Notes for principal, accrued and unpaid interest (including Additional Interest), if any, payment of the Fundamental Change Repurchase Price, if applicable, or payment of the Redemption Price, if applicable, as the case may be, ratably, without preference or priority of any kind, according to such amounts due and payable on the Notes; and

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

          The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least 15 calendar days before such record date, the Company shall mail to each Holder and the Trustee a notice, in the manner provided for in Section 13.01, that states the record date, the payment date and the amount to be paid.

     Section 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Notes.

     Section 6.12 Waiver of Stay, Extension or Usury Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at

any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

TRUSTEE

     Section 7.01 Duties of Trustee.

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

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

               (i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

               (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; provided, however, that in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

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

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

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

     Section 7.02 Rights of Trustee.

          (a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. The Trustee may, however, in its discretion make such further inquiry or investigation into such facts or matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation.

          (d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture; provided, however, that the Trustee’s conduct does not constitute willful misconduct or negligence.

     Section 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or its affiliates with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 calendar days or resign. Any Paying Agent, Registrar, Conversion Agent or co-Registrar may do the same with like rights. However, the Trustee must comply with Section 7.10.

     Section 7.05 Notice of Defaults. If a Default or Event of Default occurs and is continuing and is known to a Responsible Officer (or written notice of it is received by the Trustee) the Trustee shall mail to each Holder notice of the Default or Event of Default within 90 calendar days after it occurs; provided, however, that except in the case of a Default described in Section 6.01(a), (b) or (c), the Trustee may withhold the notice if and so long it in good faith determines that withholding the notice is in the interests of Holders.

     Section 7.06 Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation as shall be agreed upon from time to time in writing for its services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket fees and expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation, fees and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall fully indemnify each of the Trustee and any predecessor Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by it in connection with the acceptance and administration of this trust and the performance of its duties hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company of any claim for which it may seek indemnity of which a Responsible Officer has actually received written notice shall not relieve the Company of its obligations hereunder except to the extent such failure shall have materially prejudiced the Company. The Company shall defend the claim and the Trustee shall cooperate in the defense. If the Trustee is advised by counsel in writing that it may have available to it defenses which are in conflict with the defenses available to the Company, then the Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence. The Company need not pay for any settlement made by the Trustee without the Company’s consent, such consent not to be unreasonably withheld. All indemnifications and releases from liability granted hereunder to the Trustee shall extend to its officers, directors, employees, agents, attorneys, custodians, successors and assigns.

          (b) To secure the Company’s payment obligations in this Section 7.06, the Trustee and (only to the extent applicable) any predecessor Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or property held in trust to pay the principal, accrued and unpaid interest (including Additional Interest), if any, the Fundamental Change Repurchase Price, if applicable, or the Redemption Price, if applicable, on particular Notes.

          (c) The Company’s payment obligations pursuant to this Section 7.06 shall survive the resignation or removal of the Trustee and the Discharge of this Indenture. In the event that the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

     Section 7.07 Replacement of Trustee. (a) The Trustee may resign at any time by notifying the Company in writing at least 30 calendar days prior to the proposed effective date of such resignation. The Holders of a majority in aggregate principal amount of the Notes then outstanding may remove the Trustee by notifying the Trustee in writing. The Company may remove the Trustee if:

               (i) the Trustee fails to comply with Section 7.09;

               (ii) the Trustee is adjudged bankrupt or insolvent;

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

               (iv) the Trustee otherwise becomes incapable of acting.

          (b) If the Trustee resigns, is removed by the Company or by the Holders of a majority in aggregate principal amount of the Notes then outstanding or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

          (c) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall upon payment of all of its costs and the costs of its agents and counsel promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06.

          (d) If a successor Trustee does not take office within 60 calendar days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of at least 10% in aggregate principal amount of the Notes then outstanding may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

          (e) If the Trustee, after written request by any Holder, fails to comply with Section 7.09, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

          (f) Notwithstanding the replacement of the Trustee pursuant to this Section 7.07, the Company’s obligations under Section 7.06 shall continue for the benefit of the retiring Trustee.

     Section 7.08 Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee.

          (b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes

shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any such successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Trustee.

     Section 7.09 Eligibility; Disqualification. There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50.0 million as set forth in its most recent published annual report of condition.

     Section 7.10 Trustee’s Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable to the Company for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of any omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

DISCHARGE OF INDENTURE

     Section 8.01 Discharge of Liability on Notes. When (1) the Company shall deliver to the Registrar for cancellation all Notes theretofore authenticated (other than any Notes which have been replaced pursuant to Section 2.07) and not theretofore canceled or (2) all the Notes not theretofore canceled or delivered to the Registrar for cancellation shall have (a) been deposited for conversion (after all related Observation Periods have elapsed) and the Company shall have delivered to the Holders cash and (in the case of conversion) shares of Common Stock, as applicable, sufficient to pay, all amounts owing in respect of all Notes (other than any Notes which have been replaced pursuant to Section 2.07) not theretofore canceled or delivered to the Registrar for cancellation or (b) become due and payable on the Maturity Date, Fundamental Change Repurchase Date, Redemption Date, upon declaration of acceleration or otherwise, and the Company shall have deposited with the Trustee cash sufficient to pay, in the opinion of a nationally recognized firm of certified public accountants, all amounts owing in respect of all Notes (other than any Notes which have been replaced pursuant to Section 2.07) not theretofore canceled or delivered to the Registrar for cancellation, including the principal amount and interest, including any Additional Interest, accrued and unpaid to such Maturity Date, Fundamental Change Repurchase Date or other such date, and if in either case (1) or (2) the Company shall also pay or deliver or cause to be paid or delivered all other sums payable and shares of Common Stock deliverable hereunder by the Company, then this Indenture shall cease

to be of further effect with respect to the Notes (except as to (i) remaining rights of registration of transfer, substitution and exchange and conversion of Notes, (ii) rights hereunder of Holders to receive from the Trustee payments of the amounts and any shares of Common Stock then due, including interest (and any Additional Interest) with respect to the Notes and the other rights, duties and obligations of Holders, as beneficiaries hereof solely with respect to the amounts, if any, so deposited with the Trustee and (iii) the rights, obligations and immunities of the Trustee, the Authenticating Agent, the Paying Agent, the Conversion Agent and the Registrar under this Indenture), and the Trustee, on demand of the Company accompanied by an Officer’s Certificate and an Opinion of Counsel as required by Section 8.03 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture with respect to the Notes (such event, the “Discharge”); provided, however, the Company hereby agrees to reimburse the Trustee, the Authenticating Agent, the Paying Agent, the Conversion Agent and the Registrar for any costs or expenses thereafter reasonably and properly incurred by the Trustee, the Authenticating Agent, the Paying Agent, the Conversion Agent and the Registrar and to compensate the Trustee, the Authenticating Agent, the Paying Agent, the Conversion Agent and the Registrar for any services thereafter reasonably and properly rendered by the Trustee, the Authenticating Agent, the Paying Agent, the Conversion Agent and the Registrar in connection with this Indenture.

     Section 8.02 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money to the Holders entitled thereto by reason of any order or judgment of any court of governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with this Indenture and the Notes to the Holders entitled thereto; provided, however, that if the Company makes any payment of principal amount of, or interest on, any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or the Paying Agent.

     Section 8.03 Officer’s Certificate; Opinion of Counsel. Upon any application or demand by the Company to the Trustee to take any action under Section 8.01, the Company shall furnish to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with.

     For purposes of Section 9.01(10) above, the Trustee may rely on an Officer’s Certificate in determining that the changes effected in an amendment or supplement are made to conform the provisions of this Indenture to the “Description of Notes” section in the Offering Circular.

     The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under this Section 9.01 becomes effective, the Company shall mail to Holders a notice, in the manner provided for in Section 13.01, briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01.

     Section 9.02 With Consent of Holders. With the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes, including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes, the Company and the Trustee may amend or supplement this Indenture or the Notes. However, without the consent of each Holder affected, an amendment to this Indenture or the Notes may not:

(1) reduce the percentage of the principal amount of Notes then outstanding whose Holders must consent to an amendment;

(2) reduce the rate, or extend the stated time for payment, of interest (including Additional Interest, if any) on any Note;

(8) adversely affect the ranking of the Notes as senior unsecured indebtedness of the Company; or

(9) make any change to the provisions of Section 6.04, this Section 9.02 or Section 9.03.

     The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under this Section 9.02 becomes effective, the Company shall mail to Holders a notice, in the manner provided for in Section 13.01, briefly describing such amendment. The failure to give such notice to all such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

     Section 9.03 Revocation and Effect of Consents, Waivers and Actions. A consent to an amendment or a waiver by a Holder of a Note shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent or waiver is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation before the date the supplemental indenture setting forth the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective in accordance with the terms of the supplemental indenture, which shall become effective upon the execution thereof by the Trustee.

     The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 calendar days after such record date.

     Section 9.04 Notation on or Exchange of Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article 9 may, and shall if required

by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Notes.

     Section 9.05 Trustee to Sign Supplemental Indentures. Upon the written request of the Company, the Trustee shall sign any supplemental indenture authorized pursuant to this Article 9 if the amendment contained therein does not affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign such supplemental indenture. In signing such supplemental indenture, the Trustee shall be provided with, and (subject to the provisions of Section 7.01) shall be fully protected in conclusively relying upon, an Officer’s Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture and is the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

     Section 9.06 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article 9, 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 theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

CONVERSIONS

     Section 10.01 Conversion Privilege and Conversion Rate.

          (a) Upon the occurrence of any of the conditions described in clauses (i), (ii), (iii) or (iv) of this Section 10.01(a), and upon compliance with the provisions of this Article 10, a Holder shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple of $1,000 in excess thereof) of its Notes at any time prior to the Close of Business on the Scheduled Trading Day immediately preceding April 1, 2018, at a rate (the “Conversion Rate”) of 23.8126 shares of Common Stock (subject to adjustment by the Company as provided in Section 10.04) per $1,000 principal amount of the Notes (the “Conversion Obligation”) under the circumstances and during the periods set forth below. On and after April 1, 2018, regardless of such conditions and upon compliance with the provisions of this Article 10, a Holder shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple of $1,000 in excess thereof) of its Notes at the applicable Conversion Rate at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date.

               (i) Prior to the Close of Business on the Scheduled Trading Day immediately preceding April 1, 2018, a Holder may surrender all or a portion of its Notes in $1,000 principal amount or an integral multiple of $1,000 in excess thereof for conversion during the five Business Day period immediately after any ten consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of the Notes for each Trading Day of such Measurement Period was less than 98% of the product of the Last

Reported Sale Price of the Common Stock and the applicable Conversion Rate for the Notes for such Trading Day (the “Trading Price Condition”) subject to compliance with the procedures and conditions described below concerning the Trustee’s obligation to make a Trading Price determination. In connection with any conversion upon satisfaction of the Trading Price Condition, the Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Notes unless the Company has requested such determination in writing, and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price of the Notes would be less than 98% of the product of (a) the applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price of the Common Stock at such time and requests in writing that the Company require the Bid Solicitation Agent to begin determining the Trading Price of the Notes. At such time, the Company shall instruct the Bid Solicitation Agent, in writing, to determine the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day until the date on which the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of (a) the applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price of the Common Stock. If the Trading Price Condition has been met, the Company shall so notify the Holders, the Bid Solicitation Agent and the Trustee. If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of the Notes is greater than 98% of the product of (a) the applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price of the Common Stock on such date, the Company shall so notify the Holders, the Bid Solicitation Agent and the Trustee, and the Bid Solicitation Agent shall have no further obligation to determine the Trading Price of the Notes unless requested by the Company to do so again in writing pursuant to this clause (i). Notwithstanding the foregoing, if the Bid Solicitation Agent cannot reasonably obtain at least one bid for $1.0 million principal amount of the Notes from a nationally recognized securities dealer selected by the Board of Directors for the purpose of determining the Trading Price on any Trading Day, then the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of (a) the applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price of the Common Stock on such date (any such determination by the Bid Solicitation Agent shall be conclusive absent manifest error). Furthermore, if the Company does not, when obligated to do so pursuant to this clause (i), instruct the Bid Solicitation Agent to determine the Trading Price of the Notes, or if the Company so instructs the Bid Solicitation Agent, but the Bid Solicitation Agent does not make such determination, then the Trading Price per $1,000 principal amount of the Notes shall be deemed to be less than 98% of the product of (a) the applicable Conversion Rate of the Notes and (b) the Last Reported Sale Price of the Common Stock on such date.

               (ii) Prior to the Close of Business on the Scheduled Trading Day immediately preceding April 1, 2018, a Holder may surrender all or a portion of its Notes in $1,000 principal amount or an integral multiple of $1,000 in excess thereof for conversion during any calendar quarter after the calendar quarter ending September 30, 2011 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for 20 or more Trading Days in a period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding calendar quarter exceeds 130% of the applicable Conversion Price in effect on the last Trading Day of the immediately preceding calendar quarter.

               (iii) The Notes shall be convertible prior to April 1, 2018, as provided in Sections 10.01(a)(iii)(A), (B) and (C).

                    (A) In the event that the Company, prior to April 1, 2018, elects to:

                         (1) issue to all or substantially all holders of Common Stock any rights or warrants entitling them, for a period of not more than 60 calendar days after the record date for such distribution, to subscribe for or purchase Common Stock at a price per share less than the average of the Last Reported Sale Price of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or

                         (2) distribute to all or substantially all holders of Common Stock, assets (including cash) or debt securities of the Company or rights to purchase the Company’s securities, which distribution has a per share value (as determined by the Board of Directors) exceeding 10% of the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the date of declaration of such distribution, then, in either case, Holders may surrender their Notes for conversion, in $1,000 principal amount or an integral multiple of $1,000 in excess thereof, at any time on and after the date that the Company provides the notice to such Holders referred to in the next sentence until the earlier of the Close of Business on the Business Day immediately preceding the Ex-Date for such distribution or the date the Company announces that such distribution will not take place, even if the Notes are not otherwise convertible at that time. The Company shall notify Holders and the Trustee in writing of any distribution referred to in either clause (1) or (2) of this Section 10.01(a)(iii)(A) and of the resulting conversion right no later than the 30th Scheduled Trading Day prior to the Ex-Date for such issuance or distribution.

                    (B) If the Company is a party to a combination, merger, binding share exchange or sale or conveyance of all or substantially all of its properties and assets (other than in any such transaction that constitutes a Fundamental Change and/or a Make-Whole Fundamental Change, in either case, to which the provisions of Section 10.01(b) shall apply) in each case pursuant to which the Common Stock would be converted into cash, securities and/or other property that does not also constitute a Fundamental Change, then the Holders shall have the right to convert Notes, in $1,000 principal amount or an integral multiple of $1,000 in excess thereof, at any time beginning on the effective date of the transaction and ending on the 30th Scheduled Trading Day following the effective date of such transaction. The Company shall notify Holders and the Trustee in writing of the occurrence of any transaction referred to in this Section 10.01(a)(iii)(B) no later than the 4th Business Day following the effective date of such transaction).

                    (C) If the Company is a party to any transaction or event that constitutes a Fundamental Change or Make-Whole Fundamental Change, a Holder may surrender Notes for conversion, in $1,000 principal amount or an integral multiple of $1,000 in excess thereof, at any time, after the Company gives the notice referred to in the following sentence, until (i) the Fundamental Change Repurchase Date corresponding to such Fundamental Change or (ii) in the case of a Make-Whole Fundamental Change that is not also a Fundamental Change, the 30th Trading Day following the Effective Date of such Make-Whole Fundamental Change and, upon such surrender in connection with such Make-Whole Fundamental Change, the Holder may be entitled to receive Additional Shares of Common Stock, if any, as specified in

Section 10.01(b). The Company shall notify, in the manner provided for in Section 13.01, Holders and the Trustee in writing of the occurrence of the Fundamental Change or Make-Whole Fundamental Change no later than four Business Days following the Effective Date of such Fundamental Change or Make-Whole Fundamental Change, as applicable, and shall issue a press release as promptly as practicable following such Effective Date.

               (iv) If the Company calls a Holder’s Notes for Optional Redemption pursuant to Article 12, such Holder shall have the right to convert such Holder’s Notes until the Close of Business on the Business Day immediately preceding the applicable Redemption Date (or, if the Company defaults in the payment of the Redemption Price in respect of such Optional Redemption, such date on which such default is no longer continuing), after which time such right to convert will expire.

          (b) Subject to Section 10.01(a)(iii)(C), if the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert Notes in connection with a Make-Whole Fundamental Change, the Conversion Rate applicable to each $1,000 principal amount of Notes so surrendered for conversion shall be increased by a number of additional shares of Common Stock (the “Additional Shares”) as described below. Settlement of Notes tendered for conversion with respect to which Additional Shares shall be added to the Conversion Rate as provided in this Section 10.01(b) shall be settled pursuant to Section 10.02(c). For purposes of this Section 10.01(b), any conversion of Notes shall be deemed to be “in connection with” a Make-Whole Fundamental Change only if such Notes are surrendered for conversion during the time period specified in Section 10.01(a)(iii)(C) with respect to such Make-Whole Fundamental Change (regardless of whether the provisions of clauses (i), (ii) or (iv) of Section 10.01(a) or Section 10.01(a)(iii)(A) or (B) shall apply to such conversion).

               (i) The number of Additional Shares shall be determined by the Company by reference to the table attached as Schedule A hereto, based on the Effective Date of such Make-Whole Fundamental Change and the Stock Price; provided that if the actual Stock Price is between two Stock Price amounts in the table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the next higher and next lower Stock Price amounts and the two nearest Effective Dates, as applicable, based on a 365-day year; provided, further, that if (1) the Stock Price is greater than $120.00 per share of Common Stock (subject to adjustment in the same manner as the Conversion Prices are adjusted pursuant to Section 10.04), no Additional Shares shall be added to the Conversion Rate, and (2) the Stock Price is less than $35.74 per share (subject to adjustment in the same manner as the Conversion Prices are adjusted pursuant to Section 10.04), no Additional Shares shall be added to the Conversion Rate. Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 27.9798 per $1,000 principal amount of Notes (subject to adjustment in the same manner as set forth in Section 10.04).

               (ii) The Stock Prices set forth in the first row of the table in Schedule A hereto shall be adjusted by the Company as of any date on which the Conversion Rate of the Notes is adjusted as set forth in Section 10.04. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of

which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares within the table shall be adjusted in the same manner as the Conversion Rate as set forth in Section 10.04.

     Section 10.02 Exercise of Conversion Privilege.

          (a) (i) The Company shall satisfy the Conversion Obligation with respect to each $1,000 principal amount of Notes tendered for conversion in cash and shares of fully paid Common Stock, if applicable, by delivering, on the third VWAP Trading Day immediately following the last VWAP Trading Day of the related Observation Period, cash and shares of Common Stock, if any, equal to the sum of the Daily Settlement Amounts for each of the 25 VWAP Trading Days during the related Observation Period; provided that the Company shall deliver cash in lieu of any fractional share of Common Stock as provided in Section 10.03. The Daily Settlement Amounts shall be determined by the Company promptly following the last VWAP Trading Day of the Observation Period.

               (ii) Notwithstanding the provisions described above in this Section 10.02(a), in satisfaction of the Conversion Obligation, the Company may direct the Conversion Agent to surrender, on or prior to the commencement of the Observation Period, such Notes to one or more financial institutions designated by the Company for exchange in lieu of conversion. In order to accept any Notes surrendered for conversion, the designated financial institution(s) must agree to deliver, in exchange for such Notes, the cash and shares of Common Stock, if any, equal to the consideration due upon conversion (the “Conversion Consideration”) pursuant to this Section 10.02. By the Close of Business on the Scheduled Trading Day immediately preceding the start of the Observation Period, the Company shall notify, in the manner provided in Section 13.01, the Holder surrendering Notes for conversion that the Company has directed the designated financial institution(s) to make an exchange in lieu of conversion and such financial institution(s) shall be required to notify the Conversion Agent and such Holder whether it will deliver the Conversion Consideration upon exchange. If the designated financial institution(s) accept any such Notes, they shall deliver the Conversion Consideration in accordance with Section 10.02(c). Any Notes exchanged by the designated financial institution(s) shall remain outstanding. If the designated financial institution(s) agree to accept any Notes for exchange but do not timely deliver the related Conversion Consideration, or if such designated financial institution(s) do not accept the Notes for exchange, the Company shall, no later than the third VWAP Trading Day immediately following the last VWAP Trading Day of the related Observation Period, convert the Notes into cash and, if applicable, the appropriate number of shares of Common Stock due upon conversion pursuant to this Section 10.02.

          (b) Before any Holder of a Note shall be entitled to convert the same as set forth above, such Holder shall (1) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 10.02(h) and, if required, pay all taxes or duties required pursuant to Section 10.02(e), if any, and (2) in the case of a Note issued in certificated form, (A) complete and manually sign and deliver an irrevocable written notice to the Conversion Agent in the form set forth in the form of Note attached hereto as Exhibit A hereto (or a facsimile thereof) (a “Notice of Conversion”) at the office of the

Conversion Agent and shall state in writing therein the principal amount of Notes to be converted and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock, if any, to be delivered upon settlement of the Conversion Obligation to be registered, (B) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (C) if required, pay all taxes or duties required pursuant to Section 10.02(e), if any, and (D) 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 10.02(h). A Note shall be deemed to have been converted immediately prior to the Close of Business on the date (the “Conversion Date”) that the Holder has complied with the requirements set forth in this Section 10.02(b).

          No Notice of Conversion with respect to any Notes may be tendered by a Holder thereof if such Holder has also tendered a Fundamental Change Repurchase Notice and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with the applicable provisions of Section 3.02(c).

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

          (c) Delivery of the amounts owing in satisfaction of the Conversion Obligation shall be made by the Company in no event later than the date specified in Section 10.02(a). The Company shall make such delivery by paying the cash amount owed to the Holder of the Note surrendered for conversion, or such Holder’s nominee or nominees, and by issuing, or causing to be issued, and delivering to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the number of full shares of Common Stock, if any, to which such Holder shall be entitled as part of such Conversion Obligation (together with cash in lieu of any fractional share).

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

          (e) If a Holder submits a Note for conversion, subject to Section 10.07, the Company shall pay all documentary, stamp and other similar issue or transfer taxes or duties, if any, which may be imposed by the United States or any political subdivision thereof or taxing authority thereof or therein with respect to the issuance of shares of Common Stock, if any, upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests any shares of Common Stock to be issued in a name other than the Holder’s name. The Company may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Company receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the

Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulations.

          (f) Except as provided in Section 10.04, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 10.

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

          (h) Upon conversion, a Holder shall not receive any separate cash payment for accrued and unpaid interest except as set forth below. The Company’s settlement of the Conversion Obligation as described above shall be deemed to satisfy its obligation to pay the principal amount of the Note and accrued and unpaid interest to, but not including, the Conversion Date. As a result, accrued and unpaid interest to, but not including, the Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the preceding sentence, if Notes are converted after the Close of Business on a Regular Record Date, Holders of such Notes as of the Close of Business on the Regular Record Date shall receive the interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the Close of Business on any Regular Record Date to the Open of Business on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest payable on the Notes so converted; provided, however, that no such payment need be made (i) if the Company has called Notes for Optional Redemption pursuant to Article 12; (ii) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; (iii) to the extent of any overdue interest existing at the time of conversion with respect to such Note; or (iv) with respect to any Conversion Date that occurs during the period from the Close of Business on the Regular Record Date immediately preceding the Maturity Date to the Maturity Date. Except as described above, no payment or adjustment shall be made for accrued interest on converted Notes.

     Section 10.03 Fractions of Shares. If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock which shall be issuable upon conversion thereof shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. No fractional share of Common Stock shall be issued upon conversion of any Note or Notes. Instead of any fractional share of Common Stock that would otherwise be issuable upon conversion of any Notes (or specified portions thereof), the Company shall calculate and pay a cash adjustment in respect of such fraction (calculated to the nearest 1/100th of a share) in an amount equal to the same fraction of the Daily VWAP of the Common Stock on the last VWAP Trading Day of the relevant Observation Period.

     Section 10.04 Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows; provided that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (as a result of holding the

Notes, and at the same time as holders of the Common Stock participate) in any of the transactions described below as if such Holders held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holders, without having to convert their Notes:

          (a) In case the Company shall exclusively issue shares of Common Stock as a dividend or distribution on shares of Common Stock, or shall effect a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:

CR´

=

CRo

x

OS´

OSo

where,

CR_o = the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Date for such dividend or distribution or the effective date of such share split or combination, as the case may be;

CR´ = the Conversion Rate in effect immediately after the Open of Business on such Ex-Date or such effective date, as the case may be;

OS_o = the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Date or such effective date, as the case may be; and

OS´ = the number of shares of Common Stock that will be outstanding immediately after giving effect to such dividend or distribution or immediately after the effective date of such share split or combination, as the case may be.

          Any adjustment to the Conversion Rate made under this clause (a) shall become effective immediately after the Open of Business on the Ex-Date for such dividend or distribution or the effective date of such share split or combination, as the case may be. If any dividend or distribution of the type described in this Section 10.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors (or a committee thereof) determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

          (b) In case the Company shall issue to all or substantially all holders of its outstanding shares of Common Stock any rights, options or warrants entitling them for a period of not more than 60 calendar days after the record date for such distribution to subscribe for or purchase shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance, the Conversion Rate shall be increased based on the following formula:

CR´

=

CRo

x

OSo + X

OSo + Y

where,

CR_o = the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Date for such issuance;

CR´ = the Conversion Rate in effect immediately after the Open of Business on such Ex-Date;

OS_o = the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Date;

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, option or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement of such issuance.

     Any increase made under this Section 10.04(b) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Date for such issuance. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to 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 Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Date for such issuance had not occurred.

          (c) In case the Company shall distribute to all or substantially all holders of its Common Stock shares of any class of Capital Stock of the Company, evidences of its indebtedness or other assets or property of the Company (excluding: (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 10.04(a) or (b); (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 10.04(d); (iii) rights issued pursuant to a stockholder rights plan adopted by the Company as described in Section 10.04(q); (iv) any dividends and distributions in connection with a reclassification, change, consolidation, merger, conveyance, transfer, sale, lease or other disposition resulting in a change in the conversion consideration pursuant to Section 10.10; and (v) any dividend and distributions described below in this Section 10.04(c) with respect to Spin-Offs) (any such shares of Capital Stock, evidences of indebtedness or other assets or property, subject to clauses (i) — (v) of the immediately preceding parenthetical, the “Distributed Property”), then the Conversion Rate shall be increased based on the following formula:

CR´

=

CRo

x

SPo

SPo – FMV

where,

CR_o = the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Date for such distribution;

CR´ = the Conversion Rate in effect immediately after the Open of Business on such Ex-Date;

SP_o = the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding such Ex-Date; and

FMV = the fair market value as determined by the Board of Directors (or a committee thereof) of the Distributed Property to be distributed with respect to each outstanding share of Common Stock as of such Ex-Date.

          Any increase made under the portion of this Section 10.04(c) above will become effective immediately after the Open of Business on the Ex-Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of Capital Stock of the Company, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire Capital Stock of the Company or other securities that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Date for the distribution.

          With respect to an adjustment pursuant to this Section 10.04(c) where there has been a payment of a dividend or other distribution on the Common Stock in shares of Capital Stock of the Company 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 Rate shall be increased based on the following formula:

CR´

=

CRo

x

FMVo + MPo

MPo

where,

CR_o = the Conversion Rate in effect immediately prior to the Close of Business on the effective date of such Spin-Off;

CR´ = the Conversion Rate in effect immediately after the Close of Business on such effective date;

FMV_o = the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the Last Reported Sale Price set forth above as if references therein to the Common Stock were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading Day period immediately following, and including, the effective date of the Spin-Off (the “Valuation Period”); and

MP_o = the average of the Last Reported Sale Prices of the Common Stock over the Valuation Period.

          Such adjustment under the immediately preceding paragraph shall be determined immediately after the last day of the Valuation Period, but will be given effect as of the Close of Business on the effective date of the Spin-Off. If the effective date of the Spin-Off is less than 10 Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references within the immediately preceding formula to 10 consecutive Trading Days shall be deemed replaced, for purposes of calculating the affected daily Conversion Rates in respect of that conversion, with such lesser number of Trading Days as shall elapse from, and including, the effective date of the Spin-Off to, and including, the last VWAP Trading Day of such Observation Period. For purposes of determining the Conversion Rate, in respect of any conversion during the Valuation Period, references in the immediately preceding formula to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the Conversion Date in determining the applicable Conversion Rate.

          (d) In case the Company shall pay any cash dividends or distributions to all or substantially all holders of Common Stock, the Conversion Rate shall be increased based on the following formula:

CR´

=

CRo

x

SPo

SPo – C

where,

CR_o = the Conversion Rate in effect immediately prior to the Open of Business on the Ex-Date for such dividend or distribution;

CR´ = the Conversion Rate in effect immediately after the Open of Business on such Ex-Date;

SP_o = the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding such Ex-Date; and

C = the amount in cash per share distributed to holders of shares of Common Stock in such dividend or distribution.

          Such increase shall become effective immediately after the Open of Business on the Ex-Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors (or a committee thereof) determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP_o” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of the Common Stock equal to the Conversion Rate on the Ex-Date for such cash dividend or distribution.

          (e) In case the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock (other than an odd-lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the average of the Last Reported 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 Rate will be increased based on the following formula:

CR´

=

CRo

x

AC + (SP´ x OS´)

OSo x SP´

where,

CR_o = the Conversion Rate in effect immediately prior to the Open of Business on the Trading Day next succeeding the Expiration Date;

CR´ = the Conversion Rate 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 (or a committee thereof) paid or payable for shares of Common Stock purchased in such tender or exchange offer;

OS_o = the number of shares of Common Stock outstanding immediately prior to the Expiration Date (before giving effect to such tender offer or exchange offer);

OS´ = the number of shares of Common Stock outstanding immediately after the Expiration Date (after giving effect to such tender offer or exchange offer); and

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

          Such increase in the Conversion Rate under this Section 10.04(e) shall be determined as of the Close of Business on the 10th Trading Day next succeeding the Expiration Date but will be given effect as of the Open of Business on the Trading Day next succeeding the Expiration Date. If the Trading Day next succeeding the Expiration Date is less than 10 consecutive Trading Days prior to, and including, the end of the Observation Period in respect of any conversion, references within this Section 10.04(e) to 10 consecutive Trading Days shall be deemed replaced, for purposes of calculating the affected daily Conversion Rates in respect of that conversion, with such lesser number of Trading Days as shall elapse from, and including, the Trading Day next succeeding the Expiration Date to, and including, the last VWAP Trading Day of such Observation Period. For purposes of determining the Conversion Rate, in respect of any conversion during the 10 consecutive Trading Days commencing on the Trading Day next succeeding the Expiration Date, references within this Section 10.04(e) to 10 consecutive 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 relevant Conversion Date.

          For purposes of this Section 10.04 the term “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which shares of the Common Stock (or other applicable security) are exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise).

          (f) In addition to those required by Sections 10.04(a) through (e), and to the extent permitted by applicable law and subject to the listing standards of The NASDAQ Global Market, the Company from time to time may increase the Conversion Rate by any amount for a period of at least 20 calendar days if the Board of Directors determines (which determination shall be conclusive) that such increase would be in the Company’s best interest. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall deliver to the Holder of each Note, in the manner provided for in Section 13.01, a notice of such increase at least 15 calendar days prior to the date the increased Conversion Rate takes effect, in accordance with applicable law, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. In addition, subject to the listing standards of The NASDAQ Global Market, the Company may also (but is not required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with any dividend or distribution of shares (or rights to acquire shares) or similar event.

          (g) Notwithstanding the foregoing, if any adjustment to the Conversion Rate described in Sections 10.04(a) through (e) becomes effective and, but for this provision, a Holder that has converted its Notes would receive shares of Common Stock based on an adjusted Conversion Rate and would be a record holder of such shares of Common Stock on the record date, effective date or expiration date for the dividend, distribution or other event giving rise to the adjustment or otherwise participates in such dividend, distribution or other event giving rise to the adjustment as a result of being treated as a holder of record of such shares of Common Stock, then, in lieu of receiving shares of Common Stock at such an adjusted Conversion Rate, the Company will adjust the amount of cash and the number of shares of Common Stock that the Company will deliver to such Holder as the Company determines is appropriate to reflect such Holder’s participation in the related dividend, distribution or other event giving rise to such adjustment.

          (h) If any dividend, distribution or issuance described above is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate that would have been in effect if such dividend, distribution or issuance had not been declared. If the application of any of the foregoing formulas (other than in connection with a share combination or a readjustment pursuant to the immediately preceding sentence or a readjustment set forth under Section 10.04(a)-(e)) would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made.

          (i) Except as stated in this Indenture, the Company will not adjust the Conversion Rate for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities.

          (j) Without limiting the foregoing Section 10.04(i), no adjustment to the Conversion Rate need be made:

               (i) 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 securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan;

               (ii) upon the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries;

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

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

               (v) for accrued and unpaid interest (including any Additional Interest).

          (k) All calculations and other determinations under this Article 10 shall be made by the Company and shall be made to the nearest cent or to the nearest one-ten thousandth (1/10,000) of a share, as the case may be. No adjustment shall be made for the Company’s issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common Stock or convertible or exchangeable securities, other than as provided in this Section 10.04. No adjustment shall be made to the Conversion Rate unless such adjustment would require a change of at least 1% in the Conversion Rate then in effect at such time. The Company shall carry forward any adjustments that are less than 1% of the Conversion Rate and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1% (1) annually, on the anniversary of the Issue Date and (2) upon conversion of any Note (and on each VWAP Trading Day of the related Observation Period). Except as described in this Section 10.04 or in Section 10.01(b), the Company will not adjust the Conversion Rate.

          (l) In any case in which this Section 10.04 provides that an adjustment shall become effective immediately after (1) the Ex-Date for an event or (2) the last date on which tenders or exchanges may be made pursuant to any tender or exchange offer pursuant to Section 10.04(e) (each, an “Adjustment Determination Date”), the Company may elect to defer until the occurrence of the applicable Adjustment Event (x) issuing to the Holder of any Note converted after such Adjustment Determination Date and before the occurrence of such Adjustment Event, the additional cash and, if applicable, shares of Common Stock or other securities issuable upon such conversion by reason of the adjustment required by such Adjustment Event over and above the amounts deliverable upon such conversion before giving effect to such adjustment and

(y) paying to such Holder any amount in cash in lieu of any fraction pursuant to Section 10.03. For purposes of this Section 10.04(l), the term “Adjustment Event” shall mean:

               (i) in any case referred to in clause (1), the date any dividend or distribution of Common Stock, shares of Capital Stock, evidences of indebtedness, other assets or property or cash is paid or made, the effective date of any share split or combination or the date of expiration of any rights or warrants, and

               (ii) in any case referred to in clause (2), the date a sale or exchange of Common Stock pursuant to such tender or exchange offer is consummated and becomes irrevocable.

          (m) For purposes of this Section 10.04, subject to Section 10.04(c) hereof, the number of shares outstanding at any time will include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock, but, so long as the Company does not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company, will not include shares of Common Stock held in the treasury of the Company.

          (n) With respect to a conversion of Notes pursuant to this Article 10, at and after the Close of Business on the last VWAP Trading Day (the “Relevant Date” ) of the related Observation Period, the Person in whose name any certificate representing any shares of Common Stock issuable upon such conversion is registered shall be treated as a stockholder of record of the Company on such Relevant Date. On and after the Conversion Date with respect to a conversion of Notes pursuant hereto, all rights of the Holders of such Notes shall terminate, other than the right to receive the consideration deliverable upon conversion of such Notes as provided herein. A Holder of a Note is not entitled, as such, to any rights of a holder of Common Stock until, if such Holder converts such Note and is entitled pursuant hereto to receive shares of Common Stock in respect of such conversion, the Close of Business on the Relevant Date or respective Relevant Dates, as the case may be, with respect to such conversion.

          (o) Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Price, the Daily VWAP, the Daily Conversion Value and/or the Daily Settlement Amount over a span of multiple days (including with respect to an Observation Period and/or the Stock Price), the Company shall make appropriate adjustments (determined in good faith by the Board of Directors), to the extent no corresponding adjustment is otherwise made pursuant to the provisions of this Section 10.04, to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Date of the event occurs, at any time during the period when such Last Reported Sale Price, Daily VWAP, Daily Conversion Value and/or Daily Settlement Amount is to be calculated.

          (p) Notwithstanding anything herein or in the Notes to the contrary, no adjustment shall be made to the Conversion Rate if Holders participate (as a result of holding the Notes, and at the same time as holders of Common Stock participate) in any of the transactions set forth in Sections 10.04(a) through (e) as if such Holders of the Notes held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holders, without having to convert their Notes.

          (q) To the extent that the Company has a preferred stock rights plan in effect upon conversion of the Notes into Common Stock, Holders will receive, in addition to any Common Stock, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common Stock, in which case the conversion rate will be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of indebtedness or assets as described in clause Section 10.04(c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.

     Section 10.05 Notice of Adjustments of Conversion Rate. Whenever the Conversion Rate is adjusted as herein provided:

          (a) the Company shall compute the adjusted Conversion Rate in accordance with Section 10.04 and shall prepare an Officer’s Certificate setting forth the adjusted Conversion Rate and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall promptly be filed with the Trustee and with each Conversion Agent (if other than the Trustee); and

          (b) upon each such adjustment, the Company shall provide a notice to all Holders, in the manner provided for in Section 13.01, stating that the Conversion Rate has been adjusted and setting forth the adjusted Conversion Rate.

          Neither the Trustee nor any Conversion Agent shall be under any duty or responsibility with respect to any such certificate or the information and calculations contained therein, except to exhibit the same to any Holder desiring inspection thereof at its office during normal business hours.

     Section 10.06 Company to Reserve Common Stock. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, for the purpose of effecting the conversion of Notes, the full number of shares of Common Stock then issuable upon the conversion of all outstanding Notes.

     Section 10.07 Taxes on Conversions. Except as provided in the next sentence, the Company shall pay any and all taxes and duties that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Notes pursuant hereto. The Company shall not, however, be required to pay any tax or duty that may be payable in respect of (i) income of the Holder, or (ii) any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Note or Notes to be converted, and no such issue or delivery shall be made unless and until the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid.

     Section 10.08 Certain Covenants. Before taking any action which would cause an adjustment to the Conversion Rate that would result in reducing the Conversion Price below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company shall take all corporate action which it reasonably determines may be necessary in order that the Company may validly and legally issue such shares of Common Stock at such adjusted Conversion Rate.

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

     The Company further covenants that if at any time the Common Stock shall be listed for trading on any other national securities exchange the Company shall, if permitted and required by the rules of such exchange, list and keep listed, so long as the Common Stock shall be so listed on such exchange, all Common Stock issuable upon conversion of the Notes.

     Section 10.09 Cancellation of Converted Notes. All Notes delivered for conversion (other than Notes that are to be exchanged pursuant to Section 10.02(a)(iii)) shall be delivered to the Trustee or its agent and canceled by the Trustee as provided in Section 2.10.

     Section 10.10 Provision in Case of Effect of Reclassification, Consolidation, Merger or Sale. In the event of any:

          (a) reclassification of the Common Stock;

          (b) consolidation, merger or combination involving the Company; or

          (c) sale or conveyance to another Person of all or substantially all of the consolidated assets of the Company and its Subsidiaries substantially as an entirety; in which holders of the outstanding Common Stock would be entitled to receive cash, securities or other property (including cash or any combination thereof) for their shares of Common Stock (each such event, a “Merger Event”), then at and after the effective time of such Merger Event, subject to the provisions of Section 10.01, the right to convert each $1,000 principal amount of Notes into cash and shares of the Common Stock, if any, will be changed into the right to convert each $1,000 principal amount of Notes into cash and Units of Reference Property, subject to the immediately following sentence, based on the kind and amount of cash, securities or other property (including cash or any combination thereof) that a holder of a number of shares of the Common Stock equal to the Conversion Rate then in effect immediately prior to such Merger Event would have owned or otherwise been entitled to receive upon the occurrence of such Merger Event (the type, amount and kind (and in the same proportions) of such cash, securities or other property, the “Reference Property” with respect to such Merger Event, and the Reference Property that a holder of one share of the Common Stock would have received in such Merger Event, a “Unit of Reference Property”). In particular, after such effective time, a Holder converting its Notes will receive:

               (i) the amount otherwise payable in cash upon conversion of the Notes as set forth in Section 10.01 or 10.02 hereof will continue to be payable in cash; and

               (ii) in lieu of each share of the Common Stock, if any, otherwise deliverable upon conversion as set forth in Section 10.01 or 10.02, a Unit of Reference Property. the Daily Conversion Value, the Daily VWAP and the Last Reported Sale Price will, to the extent possible, be calculated on the value of a Unit of Reference Property.

For purposes of this Section 10.10, in the case of a Merger Event that causes the Common Stock to be converted into the right to receive more than a single type of consideration (based in part upon any form of stockholder election), a Unit of Reference Property will be deemed to be (i) the weighted average of the types and amounts of consideration received by the holders of the Common Stock that affirmatively make such an election or (ii) if no holders of the Common Stock affirmatively make such an election, the types and amounts of consideration actually received by such holders, in each case, per share of Common Stock. The Company will notify Holders of the weighted average as soon as practicable after such determination is made.

          The Company and the Trustee (and any Successor Person, if applicable) shall, concurrently with the effective time of the Merger Event, execute a supplemental indenture to effect the requirements therefor pursuant to this Indenture. If the Reference Property for such Merger Event includes shares of stock or other securities or assets of a Person other than the Company, for such Merger Event, then such other Person will also execute such supplemental indenture and such supplemental indenture will contain whatever additional provisions the Board of Directors considers to be reasonably necessary to protect the Holders. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, in the manner provided for in Section 13.01, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

          In the event a supplemental indenture is executed pursuant to this Section 10.10, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the type, amount and kind of cash, securities or property that will constitute the Reference Property after any such Merger Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with.

          The above provisions of this Section 10.10 shall similarly apply to any successive Merger Event.

     Section 10.11 Responsibility of Trustee for Conversion Provisions. The Trustee, subject to the provisions of Section 7.02, and any Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent of any such adjustment when made, or with respect to the method employed, herein or in any supplemental indenture provided to be employed, in making the same, or whether a supplemental indenture need be entered into. Neither the Trustee, subject to the provisions of Section 7.02, nor any Conversion Agent shall be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any other securities or property or cash, which may at any time be issued or delivered upon the conversion of any Notes; and it or they do not make any representation with respect thereto. Neither the Trustee, subject to the provisions of Section 7.02, nor any Conversion Agent shall be responsible for any failure of the Company to make or calculate any cash payment or to issue, transfer or deliver any shares of Common Stock or share certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion; and the Trustee, subject to the provisions of Section 7.02, and any Conversion Agent shall not be responsible for any failure of the Company to comply with any of the covenants of the Company contained in this Article 10.

     Section 10.12 Notice to Holders Prior to Certain Actions. In case of any:

          (a) action by the Company or one of its Subsidiaries that would require an adjustment to the Conversion Rate pursuant to Section 10.04;

          (b) Merger Event; or

          (c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries; then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Register, as promptly as possible but in any event at least 10 calendar days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Merger Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Merger Event, dissolution, liquidation or winding-up.

     Section 10.13 Limit on Issuance of Shares of Common Stock upon Conversion. Notwithstanding anything to the contrary in this Indenture, if an event occurs that would result in an increase in the Conversion Rate by an amount in excess of limitations imposed by any shareholder approval rules or listing standards of The NASDAQ Global Market that are

applicable to the Company, the Company will, at its option, either obtain stockholder approval of any issuance of Common Stock upon conversion of the Notes in excess such limitations or deliver cash in lieu of any shares of Common Stock otherwise deliverable upon conversions in excess of such limitations based on the Daily VWAP on each VWAP Trading Day of the relevant Observation Period in respect of which, in lieu of delivering shares of Common Stock, the Company delivers cash pursuant to this Section 10.13.

PAYMENT OF INTEREST

     Section 11.01 Payment of Interest. The Company shall pay interest on the Notes at a rate of 1.50% per annum, payable semi-annually in arrears on January 1 and July 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 on January 1, 2012. Interest on a Note shall be paid to the Holder in whose name such Note was registered at the Close of Business on June 15 or December 15 (each, a “Regular Record Date”), whether or not a Business Day, as the case may be, immediately preceding the relevant Interest Payment Date, and shall be computed on the basis of a 360-day year composed of twelve 30-day months. Payment of the Fundamental Change Repurchase Price, Redemption Price, principal and interest that are not made when due will accrue interest per annum at the then-applicable interest rate from the required payment date. If the Conversion Date for a Note occurs after a Regular Record Date but on or before the corresponding Interest Payment Date, the interest payable on such Interest Payment Date will be paid to the Holder of such Note on such Regular Record Date notwithstanding the conversion of such Note.

     Section 11.02 Defaulted Interest. Any installment of interest that is payable, but is not punctually paid or duly provided for on any Interest Payment Date (“Defaulted Interest”), shall forthwith cease to be payable to the Holders in whose names the Notes were registered on the Regular Record Date applicable to such installment of interest. Defaulted Interest (including any interest on such Defaulted Interest) may be paid by the Company, at its election, as provided in Section 11.02(a) or (b).

          (a) The Company may elect to make payment of any Defaulted Interest (including any interest on such Defaulted Interest) to the Holders in whose names the Notes are registered at the Close of Business on a special record date for the payment of such Defaulted Interest (a “Special Record Date”), which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Holders entitled to such Defaulted Interest as provided in this Section 11.02(a). Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special

Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be provided in the manner provided for in Section 13.01, not less than 10 calendar days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Holders in whose names the Notes are registered at the Close of Business on such Special Record Date and shall no longer be payable pursuant to Section 11.02(b).

          (b) Alternatively, the Company may make payment of any Defaulted Interest (including any interest on such Defaulted Interest) in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Section 11.02(b), such manner of payment shall be deemed practicable by the Trustee.

     Section 11.03 Interest Rights Preserved. Subject to the foregoing provisions of this Article 11 and, to the extent applicable, Section 2.06 and Section 2.07, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

OPTIONAL REDEMPTION

     Section 12.01 Right to Redeem.

          (i) Beginning July 1, 2015, the Company may, at its option, redeem any or all of the Notes, except for the Notes that the Company is required to repurchase pursuant to Article 3, if the Last Reported Sale Price of the Common Stock for 20 or more Trading Days in the period of 30 consecutive Trading Day ending on the Trading Day immediately prior to the date on which the Company provides notice of such redemption exceeds 140% of the applicable Conversion Price in effect on each such Trading Day (such redemption, an “Optional Redemption”).

          (ii) If the Company elects to redeem Notes pursuant to an Optional Redemption, the redemption price (the “Redemption Price”) shall be payable in cash and shall be equal to 100% of the principal amount of Notes being redeemed, together with accrued and unpaid interest to, but not including, the Redemption Date (or, in the case of a Default by the Company in the payment of the Redemption Price, the day on which such Default is no longer continuing), plus the applicable Make-Whole Premium in connection with such Optional Redemption; provided, however, that, notwithstanding the foregoing or Section 12.01(iv), if Notes are redeemed on a date that is after the Close of Business on a Regular Record Date and prior to the Close of Business on the corresponding Interest Payment Date, the accrued interest payable in respect of such Interest Payment Date shall not be payable to Holders of the Notes to whom the Principal Amount of the Notes being redeemed pursuant to the Optional Redemption is paid, and shall instead pay the full amount of the relevant interest payment on such Interest Payment Date to the Holder of record on the relevant Regular Record Date for the corresponding Interest Payment Date and the Make-Whole Premium payment made on such Notes to converting or redeeming

Holders shall equal the present values of all remaining interest payments, starting with the next Interest Payment Date for which interest has not been provided for pursuant to this Section 12.01, calculated as described pursuant to this Section 12.01.

          (iii) No Notes may be redeemed by the Company pursuant to an Optional Redemption if (x) the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Redemption Date and/or (y) the Company has failed to pay any interest due on the Notes and such failure to pay is continuing.

          (iv) If the Company redeems Notes as provided in this Section 12.01, the Company shall make a payment (the “Make-Whole Premium”) in cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s option, equal to the sum of the present values of the remaining scheduled payments of interest that would have been made on the Notes to be redeemed had such Notes remained outstanding from the Redemption Date to the Maturity Date (excluding interest accrued to, but excluding, the Redemption Date (or, in the case of a Default by the Company in the payment of the Redemption Price, the day on which such Default is no longer continuing) which is otherwise paid pursuant to Section 12.01(ii)). The present values of the remaining interest payments will be computed using a discount rate equal to 2.5%. If the Company elects to pay some or all of the Make-Whole Premium in shares of Common Stock, then the number of shares of Common Stock a Holder will receive shall be that number of shares that have a value equal to the amount of the Make-Whole Premium payment to be paid to such Holder in shares of Common Stock, divided by the product of the average of the Last Reported Sale Prices of the Common Stock for the five consecutive Trading Days immediately preceding, and including, the third Trading Day prior to the date of the Optional Redemption multiplied by 97.5%. Notwithstanding the foregoing, the Company may only elect to pay the Make-Whole Premium in shares of Common Stock to the extent the payment of the Make-Whole Premium would comply with the listing standards of The NASDAQ Global Market or any stock exchange on which the shares of Common Stock or other shares of Capital Stock of the Company are then listed, as applicable. The Company shall make these Make-Whole Premium payments on all Notes called for Optional Redemption prior to the Maturity Date, including Notes subject to Optional Redemption that are converted after the date the Company delivers the notice of such Optional Redemption. Notwithstanding the foregoing, if the Company sets a Redemption Date between a Regular Record Date and the corresponding interest payment date, we will not pay accrued interest to any redeeming holder, and will instead pay the full amount of the relevant interest payment on such interest payment date to the holder of record on such a Regular Record Date.

          (v) Except as provided in this Section 12.01, the Notes shall not be redeemable by the Company.

     Section 12.02 Selection of Notes to be Redeemed. If less than all the Notes are to be redeemed pursuant to an Optional Redemption, the Trustee shall select the Notes to be redeemed (in principal amounts of $1,000 or integral multiples of $1,000 in excess thereof) by lot, or on a pro rata basis or by any other method the Trustee considers reasonable and in accordance with Applicable Procedures (so long as such method is not prohibited by the rules of The NASDAQ Global Market or any stock exchange on which the shares of Common Stock or other shares of Capital Stock of the Company are then listed, as applicable); provided however that no Note of a

principal amount of $1,000 or less shall be redeemed in part. The Trustee shall make the selection within 7 days from its receipt of the Notice of Optional Redemption from the Company delivered pursuant to Section 12.03 from outstanding Notes not previously called for redemption.

     Section 12.03 Notice of Optional Redemption. Not more than 60 calendar days but not less than 28 Scheduled Trading Days prior to a Redemption Date in connection with an Optional Redemption, the Company shall mail a written notice of redemption (a “Notice of Optional Redemption”) by first-class mail, postage prepaid (in the case of Notes held in book entry form, by electronic transmission), to the Trustee, the Paying Agent and each Holder of Notes to be redeemed, at their addresses set forth in the Register.

     The Notice of Optional Redemption shall specify the Notes to be redeemed and shall state:

          (i) the Redemption Date;

          (ii) the Redemption Price

          (iii) the Applicable Conversion Rate and Applicable Conversion Price;

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

          (v) that Notes called for redemption may be converted at any time before the Close of Business on the Business Day immediately preceding the Redemption Date (or, if the Company fails to pay the Redemption Price, such date on which the Company pays the Redemption Price), at which time the right of the Holder to convert such Notes called for redemption will expire;

          (vi) that Holders who want to convert Notes must satisfy the requirements set forth therein and in this Indenture;

          (vii) that Notes called for redemption must be surrendered to the Paying Agent for cancellation to collect the Redemption Price;

          (viii) if fewer than all the outstanding Notes are to be redeemed, the certificate numbers (if such Notes are held other than in global form) and Principal Amounts of the particular Notes to be redeemed;

          (ix) that, unless the Company defaults in making payment of such Redemption Price, interest will cease to accrue on and after the Redemption Date; and

          (x) the CUSIP number of the Notes.

          At the Company’s written request delivered at least 5 Business Days prior to the date such Notice of Optional Redemption is to be given (unless a shorter time period shall be acceptable to the Trustee), the Trustee shall give the Notice of Optional Redemption to each Holder of Notes to be redeemed in the Company’s name and at the Company’s expense.

     Section 12.04 Effect of Notice of Optional Redemption. Once a Notice of Optional Redemption is given, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price stated in the Notice of Optional Redemption except for Notes that are converted in accordance with the terms of this Indenture. Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption Price stated in the Notice of Optional Redemption.

     Section 12.05 Deposit of Redemption Price. If the Paying Agent holds money sufficient to pay the Redemption Price with respect to any Notes for which a Notice of Optional Redemption has been given, then, immediately on and after the Redemption Date, interest on such Notes shall cease to accrue, whether or not the Notes are delivered to the Paying Agent, and all other rights of the Holders of such Notes shall terminate, other than the right to receive the Redemption Price of such Note.

     Section 12.06 Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part pursuant to an Optional Redemption, the Company shall execute and the Trustee shall authenticate and deliver to the Holder a new Note in an authorized denomination, which shall be $1,000 or an integral multiple of $1,000 in excess thereof, equal in principal amount to the unredeemed portion of the Note surrendered. The Company shall not be required to register the transfer of or exchange any Notes selected for redemption, in whole or in part, except the unredeemed portion of any Notes being redeemed in part.

          If the Trustee selects a portion of a Holder’s Notes for Optional Redemption and the Holder converts a portion of such Holder’s Notes, the converted portion of such Holder’s Notes shall be deemed to be from the portion selected for redemption, except to the extent of the excess, if any, of such converted portion over such portion selected for redemption.

1.50% Convertible Senior Note due 2018

          This Note is one of a duly authorized issue of Notes of the Company, designated as its 1.50% Convertible Senior Notes due 2018 (the “Notes”), initially issued in the aggregate principal amount of $120,000,000, all issued or to be issued under and pursuant to an Indenture dated as of June 20, 2011 (the “Indenture”), between the Company and Wells Fargo Bank, National Association (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

          In case an Event of Default shall have occurred and be continuing, the principal of, and interest on, all Notes may be declared, by either the Trustee or Holders of not less than 25% in aggregate principal amount of the outstanding Notes, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

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

          The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in certain other circumstances, with the consent of the Holders of at least a majority in aggregate principal amount of the outstanding Notes, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

          No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal (including the Redemption Price, if applicable, and the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest, including Additional Interest, if any, on, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed.

          The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and integral multiples of $1,000 in excess thereof. At the office or agency of

the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations. The Company shall not charge a service charge for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges that may be imposed in connection with the registration of, transfer or exchange of the Notes from the Holder requesting such transfer or exchange.

          No sinking fund is provided for the Notes. All or any portion (in principal amounts of $1,000 or an integral multiple of $1,000 in excess thereof) of the outstanding Notes are subject to redemption, at the option of the Company during certain periods, upon the occurrence of certain conditions and subject to certain exceptions, at a price equal to the Redemption Price, as specified in the Indenture.

          Upon the occurrence of a Fundamental Change, the Holder has the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof (in principal amounts of $1,000 or an integral multiple of $1,000 in excess thereof) on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price.

          Subject to the provisions of the Indenture, the Holder hereof has the right, at its option, during certain periods and upon the occurrence of certain conditions specified in the Indenture, prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date, to convert any Notes or portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof, into cash and shares of Common Stock, if any, at the Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
