To elect to pay the Special Interest as the sole remedy for a Reporting Event of Default, the Company must deliver written notice of such election to the Holder prior to the date on which such Reporting Event of Default first occurs. Any such notice must include a brief description of the report that the Company failed, or will fail, to file, a statement that the Company is electing to pay the Special Interest and the date on which such Reporting Event of Default will occur. If a Reporting Event of Default occurs and the Company fails to timely deliver such notice for such Reporting Event of Default or fails to pay the Special Interest, this Note will be subject to acceleration under Section 6.02(a) on account of such Reporting Event of Default.

(d)          Other Events of Default . Notwithstanding anything to the contrary herein, if the Company elects to pay Special Interest with respect to any Reporting Event of Default, the Company’s election will not affect the rights of the Holder with respect to any other Event of Default, including with respect to any other Reporting Event of Default; provided , that, for the avoidance of doubt, in no event will the Company be obligated to pay Special Interest at a rate greater than 0.50% per annum on the principal amount of this Note.

Section 6.05          Waiver of Past Defaults . If an Event of Default described in Sections 6.01(a)(i) , 6.01(a)(ii) , 6.01(a)(iv) or 6.01(a)(vi) (which, in the case of Section 6.01(a)(vi) only, relates to a covenant that cannot be amended without the consent of each affected holder of a note in the Series) or a Default that would lead to such an Event of Default occurs and is continuing, such Event of Default or Default may be waived only with the consent of each affected holder of a note in the Series. Every other Event of Default or Default may be waived by the holders of a majority of the aggregate principal amount of the outstanding Series (including consents obtained in connection with a repurchase of, or tender offer or exchange offer for, notes in the Series). Whenever any Event of Default is so waived, it will cease to exist, and whenever any Default is so waived, it will be deemed cured and any Event of Default arising therefrom will be deemed not to occur. However, no such waiver will extend to any subsequent or other Default or Event of Default or impair any consequent right

Notwithstanding anything to the contrary in this Note, if the Holder tenders a Repurchase Notice with respect to this Note in accordance with Article 3 , this Note may not be converted except to the extent (i) this Note is not subject to such Repurchase Notice, (ii) such Repurchase Notice is withdrawn in accordance with Article 3 or (iii) the Company fails to pay the Fundamental Change Repurchase Price for this Note in accordance with Section 3.05(b) .

Section 8.02          Conversion Procedures .

(a)          General . To exercise its conversion right with respect to this Note, the Holder must (i) complete and manually sign a conversion notice in the form set forth in Exhibit A hereto, or a facsimile of such conversion notice (such notice, or such facsimile, the “ Conversion Notice ”); (ii) deliver such signed and completed Conversion Notice, which shall be irrevocable, and this Note to the Company; (iii) furnish any endorsements and transfer documents that the Company may require; and (iv) pay any amounts due pursuant to Section 8.02(d) or 8.02(e) . The first Business Day on which the Holder satisfies the foregoing requirements with respect to this Note and on which conversion of this Note is not otherwise prohibited hereunder will be the “ Conversion Date ” for this Note. If the Holder has delivered a Fundamental Change Repurchase Notice with respect to this Note, the Holder may not surrender this Note for conversion until the Holder has withdrawn such Fundamental Change Repurchase Notice in accordance with Section 3.04 . The conversion of this Note will be deemed to occur at the Close of Business on the Conversion Date for this Note, and this converted Note or portion thereof will cease to be outstanding upon conversion.

(b)          Holder of Record. If the Holder surrenders the entire principal amount of this Note for conversion, the Holder will no longer be the Holder of this Note as of the Close of Business on the Conversion Date for this Note. The person in whose name any shares of Common Stock are issuable upon conversion of this Note will become the holder of record of such shares as of the Close of Business on the Conversion Date for such conversion.

(c)          Conversions in Part . If the Holder surrenders only a portion of the principal amount of this Note for conversion, promptly after the Conversion Date for such portion, the Company will deliver to the Holder a new Note, having a principal amount equal to the aggregate principal amount of the unconverted portion of the Note surrendered for conversion.

(d)          Reimbursement of Interest upon Conversion . If the Holder converts this Note after the Close of Business on a Regular Record Date, but prior to the Open of Business on the Interest Payment Date corresponding to such Regular Record Date, then (x) the Holder at the Close of Business on such Regular Record Date shall be entitled, notwithstanding such conversion, to receive, on the date the Company delivers (or is required to deliver) the Conversion Consideration due in respect of such conversion, the unpaid interest that would have accrued on such Note to, but excluding, such Interest Payment Date (assuming, solely for these purposes, that such Note remained outstanding through such Interest Payment Date); and (y) the Holder must, upon surrender of this Note for conversion, accompany this Note with an amount of cash equal to the amount of such interest referred to in clause (x) above; provided , however , that the Holder need not make such payment (A) for conversions following the Regular Record Date immediately preceding the Maturity Date; (B) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or prior to the Business Day immediately following such Interest Payment Date; or (C) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to this Note. For the avoidance of doubt, the Holder at the Close of Business on the Regular Record Date immediately preceding the Maturity Date will be entitled to receive interest that accrues (or would have accrued) on this Note to, but excluding, the Maturity Date notwithstanding any conversion of this Note.

(e)          Taxes and Duties. If the Holder converts this Note, the Company will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of the Common Stock upon the conversion; provided , however , that if any tax is due because the Holder requested that shares of Common Stock be issued in a name other than its own, the Holder will pay such tax and the Company, until having received a sum sufficient to pay such tax, may refuse to deliver any certificates representing the shares of Common Stock being issued in a name other than that of the Holder.

(f)          Restrictions on Conversion . Notwithstanding anything to the contrary in this Note, this Note will not be convertible by the Holder, and the Company will not effect any conversion of this Note, in each case to the extent (and only to the extent) that such convertibility or conversion would result in the Holder or any of its Affiliates beneficially owning in excess of 9.99% of the then-outstanding shares of Common Stock. For these purposes, beneficial ownership and all determinations and calculations (including with respect to calculations of percentage ownership) will be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For the avoidance of doubt, if the convertibility of this Note is restricted pursuant to this Section 8.02(f) , this Note will continue to be outstanding, and its convertibility will be reinstated if and when the convertibility and conversion will not violate the limitations set forth in this Section 8.02(f) .

Section 8.03          Settlement Upon Conversion .

(a)          Conversion Obligation.

(i)          Conversion Consideration . Subject to the terms hereof, upon conversion of this Note, the consideration (the “ Conversion Consideration ”) due in respect of each $1,000 principal amount of this Note to be converted will consist of (I) a whole number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion (which, if not a whole number, will be rounded down to the nearest whole number); (II) in the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, an equivalent pro rata number of shares and (III) if such Conversion Rate is not a whole number, cash in lieu of the related fractional share in an amount equal to the product of (x) the Last Reported Sale Price per share of Common Stock on such Conversion Date (or, if such Conversion Date is not a Trading Day, the immediately preceding Trading Day) and (y) the fractional portion of such Conversion Rate.

(ii)          Delivery of Conversion Consideration . Except as set forth in Section 8.05 , the Company will pay or deliver, as the case may be, the Conversion Consideration due upon the conversion of this Note to the Holder on the third (3rd) Business Day immediately following the Conversion Date for such conversion.

(b)          Settlement of Accrued Interest and Deemed Payment of Principal . If the Holder converts this Note, the Company will not adjust the Conversion Rate to account for any accrued and unpaid interest on this Note, and, except as provided in Section 8.02(d) , the Company’s delivery of the Conversion Consideration due upon such conversion will be deemed to satisfy and discharge in full the Company’s obligation to pay the principal of this Note and accrued and unpaid interest, if any, on, this Note to, but excluding the Conversion Date. As a result, except as provided in Section 8.02(d) , any accrued and unpaid interest with respect to this Note, in the event that it is converted, will be deemed to be paid in full rather than cancelled, extinguished or forfeited.

Section 8.04          Common Stock Issued Upon Conversion .

(a)         The Company will reserve out of its authorized but unissued shares of Common Stock, and keep available to satisfy conversion of this Note, a number of shares of Common Stock sufficient to permit the conversion this Note, after giving effect to the largest number of Additional Shares that may from time to time be added to the Conversion Rate as provided in Section 8.07 .

(b)         Any shares of Common Stock delivered upon the conversion of this Note will be newly issued shares or treasury shares, duly and validly issued, fully paid, nonassessable, free from preemptive rights and free of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder or other Person to whom such shares of Common Stock will be delivered). In addition, the Company will endeavor to comply promptly with all federal and state securities laws regulating the offer and delivery of any shares of Common Stock issuable upon conversion of this Note. The Company will also use its best efforts to cause any shares of Common Stock issuable upon conversion of this Note to be listed on whatever stock exchange(s) the Common Stock is listed on the date the Holder becomes a record holder of such Common Stock.

Section 8.05          Adjustment of Conversion Rate . The Company will adjust the Conversion Rate from time to time as described in this Section 8.05 , except that the Company will not make an adjustment to the Conversion Rate if the Holder participates (other than in a share split or share combination), at the same time and upon the same terms as holders of the Common Stock, and solely as a result of holding this Note, in the relevant transaction described in this Section 8.05 without having to convert its Note and as if it held a number of shares of the Common Stock equal to the product of (i) the Conversion Rate in effect on the applicable record date, Effective Date or expiration date; and (ii) the aggregate principal amount of this Note (expressed in thousands) on such date.

(a)          Stock Dividends and Share Splits . If the Company exclusively issues to all or substantially all holders of the Common Stock shares of Common Stock as a dividend or distribution on shares of the outstanding Common Stock, or if the Company effects a share split of the Common Stock or a share combination of the Common Stock (excluding an issuance solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section 8.08(a) will apply), the Conversion Rate will be adjusted based on the following formula:

where:

Such adjustment shall become effective immediately after the Open of Business on such Ex-Dividend Date or Effective Date, as applicable. If any dividend, distribution, share split or share combination of the type described in this Section 8.05(a) is declared, but not so paid or made, the Conversion Rate will be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or to effect such share split or share combination, to the Conversion Rate that would then be in effect if such dividend, distribution, share split or share combination had not been declared or announced.

(b)          Rights, Options and Warrants . If the Company issues, to all or substantially all holders of its outstanding Common Stock, rights, options or warrants entitling such holders, for a period of not more than sixty (60) calendar days after the record date of such issuance, to subscribe for, or purchase, shares of Common Stock, at a price per share less than the average of the Last Reported Sale Prices per share of the Common Stock for the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, then, subject to the provisions described below with respect to rights issued pursuant to a stockholder rights plan, the Conversion Rate will be increased based on the following formula:

where:

Such adjustment shall become effective immediately after the Open of Business on such Ex-Dividend Date. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, including because the issued rights, options or warrants were not exercised, the Conversion Rate will be readjusted 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 will be readjusted to the Conversion Rate that would then be in effect if the Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 8.05(b) , in determining whether any rights, options or warrants entitle holders of the Common Stock to subscribe for, or purchase, shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for an issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there will be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c)          Spin-Offs and Other Distributed Property .

(i)         If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities, to all or substantially all holders of the Common Stock, excluding:

(A)         dividends, distributions, rights, options or warrants for which an adjustment was effected pursuant to Section 8.05(a) or 8.05(b) , as applicable;

(B)         dividends or distributions paid exclusively in cash for which an adjustment was effected pursuant to Section 8.05(d) ;

(C)         Spin-Offs for which the provisions described in Section 8.05(c)(ii) will apply; and

(D)         an issuance solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section 8.08(a) will apply,

then the Conversion Rate will be increased based on the following formula:

where:

Such adjustment shall become effective immediately after the Open of Business on such Ex-Dividend Date. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than the “SP ₀ ” (as defined above), in lieu of the foregoing increase, the Holder will receive, for each $1,000 principal amount of this Note outstanding on the record date for the distribution, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets or property, rights, options or warrants or other securities that the Holder would have received if the Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for such distribution (or in the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, an equivalent pro rata amount).

If any distribution of the type described in this Section 8.05(c)(i) is not so paid or made, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate will be readjusted to be the Conversion Rate that would then be in effect if such distribution had not been declared.

(ii)         With respect to an adjustment pursuant to this Section 8.05(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to an Affiliate, a Subsidiary or other business unit of the Company, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a national securities exchange or a reasonably comparable non-U.S. equivalent (a “ Spin-Off ”), but excluding an issuance solely pursuant to a Common Stock Change Event as to which the provisions described in Section 8.08(a) apply, the Conversion Rate will be increased based on the following formula:

where:

Such adjustment shall become effective immediately after the Open of Business on such Ex-Dividend Date. The adjustment to the Conversion Rate under this Section 8.05(c)(ii) will be calculated as of the Close of Business on the last Trading Day of the Valuation Period but will be given effect as of immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off. Notwithstanding anything to the contrary herein or in this Note, if necessary, the Company shall delay the settlement of any conversion of this Note where the Conversion Date occurs during the Valuation Period until the third (3rd) Business Day after the last day of the Valuation Period. If any distribution of the type described in this Section 8.05(c)(ii) is declared but not so made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such distribution had not been declared.

(d)          Cash Dividends or Distributions . If any cash dividend or distribution (other than a distribution as to which an adjustment to the Conversion Rate was effected pursuant to Section 8.05(e) ) is made to all or substantially all holders of the Common Stock, the Conversion Rate will be increased based on the following formula:

where:

Such adjustment shall become effective immediately after the Open of Business on such Ex-Dividend Date. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, the Holder will receive, for each $1,000 principal amount of this Note outstanding on the record date for such cash dividend or distribution, at the same time and upon the same terms as holders of the Common Stock, the amount of cash that the Holder would have received if the Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on such record date (or in the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, an equivalent pro rata number of shares). If any dividend or distribution of the type described in this Section 10.05(d) is declared but not so paid or made, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(e)          Tender Offers or Exchange Offers . If the Company or any Subsidiary makes a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price per share of the Common Stock on the Trading Day next succeeding the last date (the “ Expiration Date ”) on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (as it may be amended), the Conversion Rate will be increased based on the following formula:

where:

The adjustment to the Conversion Rate pursuant to this Section 8.05(e) will be calculated as of the Close of Business on the last Trading Day of the Averaging Period but will be given effect as of immediately after the Expiration Time. Notwithstanding anything to the contrary herein, if necessary, the Company shall delay the settlement of any conversion of this Note where the Conversion Date occurs during the Averaging Period until the third (3rd) Business Day after the last day of the Averaging Period.

(f)          Successive Adjustments. After an adjustment to the Conversion Rate under this Article 8 , any subsequent event requiring an adjustment under this Article 8 will cause an adjustment to the Conversion Rate as so adjusted, without duplication.

(g)          Limitations Imposed by Stock Market Listing Standards. The Company will not enter into any transaction, or take any other voluntary action, that would result in an adjustment to the Conversion Rate that would violate the listing standards of any securities exchange on which any securities of the Company may be then listed, without complying, if applicable, with the requirements of such listing standards.

(h)          Special Settlement Provisions . Notwithstanding anything to the contrary herein, if:

(i)         this Note is to be converted and, as of the Conversion Date for such conversion, any transaction or other event that requires an adjustment to the Conversion Rate pursuant to Sections 8.05(a) through (e) has occurred but has not yet resulted in an adjustment to the Conversion Rate;

(ii)        the consideration due upon such conversion consists of any shares of Common Stock; and

(iii)       such shares of Common Stock are not entitled to participate in such transaction or event because they were not held on the related record date or otherwise, then, solely for purpose of such conversion, the Company shall, without duplication, give effect to such adjustment on such Conversion Date.

In addition, notwithstanding anything to the contrary herein, if:

(i)         a Conversion Rate adjustment for any transaction or other event becomes effective on any Ex-Dividend Date pursuant to Sections 8.05(a) through (e) ;

(ii)         this Note is to be converted;

(iii)         the Conversion Date for such conversion occurs on or after such Ex-Dividend Date and on or before the related record date;

(iv)         the consideration due upon such conversion includes any whole shares of Common Stock; and

(v)         the Holder would be treated, on such record date, as the record holder of such shares of Common Stock based on a Conversion Rate that is adjusted for such event,

then such Conversion Rate adjustment shall not be given effect for such conversion. Instead, the Holder will be treated as if the Holder were, as of such record date, the record holder of such shares of Common Stock on an unadjusted basis and will participate in such transaction or event.

(i)          Shareholder Rights Plans . If the Company has a rights plan in effect when the Holder converts this Note, the Company will deliver to the Holder, to the extent the Holder receives any shares of Common Stock upon such conversion of this Note, any rights that, under the rights plan, would be applicable to a share of Common Stock, unless prior to the Conversion Date for this Note, the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 8.05(c)(i) as if, at the time of such separation, the Company had distributed to all holders of the Common Stock shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire its Capital Stock or other securities, subject to readjustment in the event of the expiration, termination or redemption of such rights.

(j)          Other Adjustments. Whenever any provision of this Note requires the calculation of the Last Reported Sale Price or a function thereof over a period of multiple days (including the Stock Price for purposes of a Make-Whole Fundamental Change), the Company will make appropriate adjustments 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-Dividend Date, Effective Date or expiration date of the event occurs, at any time during such period.

(k)          Restrictions on Adjustments . Except as a result of a reverse share split or a share combination subject to Section 8.05(a) , and except for readjustments pursuant to the last paragraph of Section 8.05(a) , readjustments pursuant to the penultimate paragraph of Section 8.05(b) , readjustments pursuant to the last paragraph of Section 8.05(c)(i) , readjustments pursuant to the penultimate paragraph of Section 8.05(c)(ii) and readjustments pursuant to Section 8.05(d) , in no event will the Conversion Rate be adjusted downward pursuant to Section 8.05(a) , (b) , (c) , (d) or (e) . In addition, notwithstanding anything to the contrary elsewhere in this Note, the Conversion Rate will not be adjusted:

(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 the Company’s securities 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 those shares 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 the preceding clause and outstanding as of the date of the Issue Date;

(iv)         upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer subject to Section 10.05(e) ;

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

(vi)         for accrued and unpaid interest.

(l)          Miscellaneous .

(i)          Certain Definitions.

(II)         For purposes of this Section 8.05 , 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.

(III)         For purposes of this Section 8.05 , the term “ Effective Date ” will mean the first date on which the Common Stock trades on the applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable.

(IV)         For purposes of this Article 8 , the term “ Ex-Dividend Date ” will mean the first date on which the shares of the Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question.

(ii)         Notices . Whenever the Company adjusts (or is required to adjust) the Conversion Rate pursuant to this Section 8.05 , the Company will promptly deliver to the Holder a written notice, which notice will include (i) a brief description of the event requiring adjustment to the Conversion Rate pursuant to this Section 8.05 ; (ii) the effective time of such adjustment; (iii) the Conversion Rate in effect immediately after such adjustment is made; and (iv) a schedule explaining, in reasonable detail, how the Company calculated such adjustment.

(iii)        All calculations and other determinations in respect of the Conversion Rate will be made by the Company to the nearest 1/10,000th of a share, with 5/100,000ths rounded upward.

Section 8.06          Voluntary Adjustments .

(a)          Best Interest Increases . The Company may, from time to time, to the extent permitted by law and the applicable rules of any exchange on which the Common Stock is listed, increase the Conversion Rate by any amount if (i) the Board of Directors determines that such increase is in the best interest of the Company; (ii) such increase is in effect for a period of at least twenty (20) Business Days; and (iii) during such period, such increase is irrevocable.

(b)          Tax-Related Increases . To the extent permitted by law and the applicable rules of any exchange on which the Common Stock is listed, the Company may (but is not required to) increase the Conversion Rate if the Board of Directors determines that such increase is advisable to avoid, or diminish, any income tax imposed on holders of the Common Stock or rights to purchase the Common Stock as a result of any dividend or distribution of shares (or rights to acquire shares) or similar event treated as such for U.S. federal income tax purposes.

(c)          Notices . Whenever the Board of Directors determines that the Company will increase the Conversion Rate pursuant to this Section 8.06 , the Company will deliver to the Holder notice of such increase at least fifteen (15) Business Days before such increase will take effect, which notice will state the increase to be made and the period during which such increase will be in effect.

Section 8.07          Adjustments Upon Certain Fundamental Changes .

(a)          General . If a Fundamental Change (determined after giving effect to the penultimate paragraph of the definition thereof, but without regard to the exclusion in clause (b)(ii) of the definition thereof) occurs (a “ Make-Whole Fundamental Change ”), and the Holder converts this Note “in connection with” such Make-Whole Fundamental Change, the Company will, in the circumstances described in this Section 8.07 , increase the Conversion Rate for this Note by the number of additional shares of Common Stock (the “ Additional Shares ”) set forth in this Section 8.07 . For purposes of this Section 8.07 , a conversion of this Note will be deemed to be “in connection with” a Make-Whole Fundamental Change if the applicable Conversion Date occurs during the period from, and including, the effective date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for the exclusion in clause (b)(ii) of the definition thereof, the thirty fifth (35th) Trading Day immediately following the effective date of such Make-Whole Fundamental Change). As promptly as practicable, but in no event later than the Business Day after the effective date of a Make-Whole Fundamental Change, the Company will notify the Holder of such effective date.

(b)          Determination of Additional Shares . The number of Additional Shares, if any, by which the Conversion Rate will be increased if the Holder converts this Note in connection with a Make-Whole Fundamental Change will be determined by reference to the table below, and will be based on the Make-Whole Fundamental Change Effective Date and the Stock Price for such Make-Whole Fundamental Change. For any Make-Whole Fundamental Change, the “ Make-Whole Fundamental Change Effective Date ” will mean the date on which such Make-Whole Fundamental Change occurs or becomes effective.

(c)          Adjustment of Stock Prices and Additional Shares . The Stock Prices set forth in the first row ( i.e. , the column headers) of the table below will be adjusted on each date on which the Conversion Rate must be adjusted pursuant to Section 8.05 . The adjusted Stock Prices will equal the Stock Prices in effect immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Conversion Rate in effect immediately prior to the adjustment giving rise to the share price adjustment; and (ii) the denominator of which is the Conversion Rate in effect immediately after the adjustment. The numbers of Additional Shares set forth in the table below will be adjusted in the same manner, at the same time and for the same events for which the Conversion Rate is adjusted pursuant to Section 8.05 .

(d)          Additional Shares Table . The following table sets forth hypothetical Make-Whole Fundamental Change Effective Dates, Stock Prices and the number of Additional Shares by which the Conversion Rate will be increased per $1,000 principal amount of this Note for the Holder that converts this Note in connection with a Make-Whole Fundamental Change having such Make-Whole Fundamental Change Effective Date and Stock Price. In the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, the Conversion Rate will be increased by an equivalent pro rata number of shares.

(e)          Use of Additional Shares Table . If the Stock Price and/or Make-Whole Fundamental Change Effective Date for a Make-Whole Fundamental Change are not set forth in the table above, then:

(A)         if the Stock Price is between two Stock Prices in the table or the Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates in the table, the number of Additional Shares by which the Conversion Rate will be increased for the Holder that converts this Note in connection with such Make-Whole Fundamental Change will be determined by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices listed in the table and the earlier and later Make-Whole Fundamental Change Effective Dates listed in the table, as applicable, based on a 365- or 366-day year, as applicable;

(B)         if the Stock Price is greater than $8.00, subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table, no Additional Shares will be added to the Conversion Rate; and

(C)         if the Stock Price is less than $0.60 per share, subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table, no Additional Shares will be added to the Conversion Rate.

Notwithstanding the foregoing, in no event will the Conversion Rate be increased as a result of this Section 8.07 to exceed 1,673.1918 shares of Common Stock per $1,000 principal amount of this Note, subject to adjustment in the same manner, at the same time and for the same events for which the Conversion Rate must be adjusted as set forth in Section 8.05 .

(f)          Settlement or Conversion . If the Holder converts this Note in connection with a Make-Whole Fundamental Change, the Company will settle such conversion by delivering Conversion Consideration in accordance with Section 8.03 ; provided , however , that notwithstanding anything to the contrary in Section 8.03 , if the Holder converts this Note in connection with a Make-Whole Fundamental Change described in clause (b)(ii) of the definition of Fundamental Change in which the holders of the Common Stock receive only cash in consideration for their shares of Common Stock, the Company will settle such conversion by delivering to the Holder, on the third (3rd) Business Day immediately following the Conversion Date for this Note, an amount of cash, for each $1,000 principal amount of this Note so converted, equal to the product of (i) the Conversion Rate on the Conversion Date applicable to this Note (including any Additional Shares added to such Conversion Rate pursuant to this Section 8.07 ) and (ii) the Stock Price for such Make-Whole Fundamental Change, or in the case of a principal amount or portion of a principal amount that is not a multiple of $1,000, an equivalent pro rata amount.

Section 8.08          Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale .

(a)          General . If any of the following events occur:

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, or represent solely the right to receive, stock (including one or more series of the Common Stock), other securities, other property or assets (including cash or any combination thereof) (any such event, a “ Common Stock Change Event ” and such stock, other securities, other property or assets, the “ Reference Property ”, and the amount and kind of Reference Property that a holder of one share of Common Stock would be entitled to receive on account of such Common Stock Change Event, a “ Reference Property Unit ”), then, notwithstanding anything to the contrary, at the effective time of such transaction, the consideration due upon a conversion of this Note will be determined in the same manner as if each reference to any number of shares of Common Stock in this Article 8 were instead a reference to the same number of Reference Property Units. For these purposes, the Last Reported Sale Price of any Reference Property Unit or portion thereof that does not consist of a class of securities will be the fair value of such Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof).

If the Reference Property consists of more than a single type of consideration (determined based in part upon any form of stockholder election), then the composition of the Reference Property Unit shall be deemed to be (a) the weighted average, per share of Common Stock, of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election; or (b) if no holders of the Common Stock affirmatively make such an election, the types and amounts of consideration actually received, per share of Common Stock, by the holders of the Common Stock. The Company shall notify the Holder of such weighted average (if applicable) as soon as practicable after such determination is made.

None of the foregoing provisions will affect the right of the Holder to convert this Note as set forth in Section 8.01 and 8.02 prior to the effective date of such Common Stock Change Event.

(b)          Notices .

(i)         As soon as practicable upon learning of the anticipated or actual effective date of any Common Stock Change Event, the Company will deliver written notice of such Common Stock Change Event to the Holder. Such Notice will include:

(A)         a brief description of such Common Stock Change Event;

(B)         the Conversion Rate in effect on the date the Company delivers such notice;

(C)         the anticipated effective date for the Common Stock Change Event;

(D)         that, on and after the effective date for the Common Stock Change Event, this Note will be convertible into Reference Property Units and cash in lieu of fractional Reference Property Units; and

(E)         the composition of the Reference Property Unit for such Common Stock Change Event.

(c)          Successive Common Stock Change Events. If more than one Common Stock Change Event occurs, this Section 8.08 will apply successively to each Common Stock Change Event.

(d)          Compliance Covenant . The Company will not become a party to any Common Stock Change Event unless its terms are consistent with this Section 8.08 .
