The Redemption Price for any Note called for Redemption is an amount in cash equal to one hundred percent (100%) of the Principal Amount of such Note plus accrued and unpaid interest on such Note to, but excluding, the Redemption Date for such Redemption; provided , however , that if such Redemption Date is after a Regular Record Date and on or before the next Interest Payment Date, then (a) the Holder of such Note at the Close of Business on such Regular Record Date will be entitled, notwithstanding such Redemption, to receive, on such Interest Payment Date, 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, if such Redemption Date is before such Interest Payment Date); and (b) the Redemption Price will not include accrued and unpaid interest on such Note to, but excluding, such Redemption Date.

Section 5.06 Redemption Notice . To call any Notes for Redemption, the Company must send to each Holder a written notice of such Redemption (a “ Redemption Notice ” ) stating (a) that the Notes have been called for Redemption, briefly describing the Company ’ s Redemption right under this Agreement; (b) the Redemption Date for such Redemption; (c) the Redemption Price for such Redemption; and (d) the place or places where Notes are to be surrendered for payment of the Redemption Price.

ARTICLE 7.
CONVERSION

Section 7.01 Right to Convert .

(a) Subject to and upon compliance with the provisions of this Agreement, each Holder shall have the right, at such Holder ’ s option, at any time prior to the Close of Business on the Business Day immediately preceding the Maturity Date, to convert the Principal Amount of such Holder ’ s Notes, or any portion of such Principal Amount that is $1,000 and any integral multiple of $1,000 in excess thereof, into shares of Common Stock (and, if applicable, cash in lieu of any fractional share of Common Stock). Notwithstanding anything to the contrary:

(i) Notes may be surrendered for conversion only after the Open of Business and before the Close of Business on a day that is a Business Day;

(ii) in no event may any Note be converted after the Close of Business on the Business Day immediately preceding the Maturity Date;

(iii) if the Company calls any Note for Redemption pursuant to ARTICLE 5 , then the Holder of such Note may not convert such Note after the Close of Business on the Business Day immediately before the applicable Redemption Date, except to the extent the Company fails to pay the Redemption Price for such Note in accordance with this Agreement; and

(iv) if a Fundamental Change Repurchase Notice is validly delivered pursuant to Section 4.04(b) with respect to any Note, then such Note may not be converted, except to the extent (i) such Note is not subject to such notice; (ii) such notice is withdrawn in accordance with Section 4.04(e) ; or (iii) the Company fails to pay the Fundamental Change Repurchase Price for such Note in accordance with this Agreement.

(b) For any Conversion Date that occurs prior to the Maturity Date (other than a conversion in connection with a Make-Whole Fundamental Change), the Company shall make an Interest Make-Whole Payment to the converting Holder equal to the sum of the remaining scheduled payments of interest that would have been made on the Notes to be converted had such Notes remained outstanding from the Conversion Date through the Maturity Date (the “ Interest Make-Whole Payment ”).

If a Conversion Date occurs 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, the Interest Make-Whole Payment will not include the accrued interest to any converting Holder and instead the Company will pay the full amount of the relevant interest payment on such Interest Payment Date to the Holder of record on such Regular Record Date. In such case, the Interest Make-Whole Payment to such converting Holders will equal the value of all remaining interest payments, starting with the next Interest Payment Date for which interest has not been provided for through the Maturity Date.

The Company shall pay any Interest Make-Whole Payment by delivering shares of Common Stock. The number of shares of Common Stock a converting Holder will receive will be the number of shares equal to the amount of the Interest Make-Whole Payment to be paid to such Holder, divided by the product of (x) 97% and (y) the simple average of the Daily VWAP of the shares for the ten (10) consecutive Trading Days ending on and including the Trading Day immediately preceding the Conversion Date.

Notwithstanding anything herein to the contrary, the number of shares the Company may deliver in connection with a conversion of the Notes, including those delivered in connection with an Interest Make-Whole Payment, will not exceed 813 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment at the same time and in the same manner as the Conversion Rate as set forth under Section 7.04. The Company will not be required to make any cash payments in lieu of any fractional share or have any further obligation to deliver any shares of Common Stock or pay any cash in excess of the threshold described above. In addition, if in

21

connection with any conversion of Notes, the Conversion Rate is adjusted pursuant to Section 7.0 7 , then such Holder will not receive the Interest Make-Whole Payment with respect to such Notes.

Section 7.02 Conversion Procedure .

(a) In order to exercise the conversion right with respect to any Notes, the Holder of any such Notes to be converted, in whole or in part, shall:

(i) complete and manually sign the conversion notice provided on the back of the Note (or a facsimile of such conversion notice) and deliver the same to the Company;

(ii) surrender the Note to the Company;

(iii) if required, furnish appropriate endorsements and transfer documents,

(iv) if required pursuant to Section 7.08 , pay any transfer taxes or duties; and

(v) if required, pay funds equal to interest payable on the next Interest Payment Date as required by Section 7.03(d) .

The date on which the Holder satisfies all of the applicable requirements set forth above is the “ Conversion Date . ”

(b) In case any Note having a Principal Amount greater than $1,000 shall be surrendered for partial conversion, the Company shall execute and deliver to the Holder of such Note, without charge to such Holder, new Notes in authorized denominations in an aggregate Principal Amount equal to the unconverted portion of such Note.

Each conversion shall be deemed to have been effected as to any such Notes (or portion thereof) on the Conversion Date for such conversion, and the Person in whose name the shares of Common Stock shall be issuable upon such conversion shall be deemed to have become the holder of record of such shares as of the Close of Business on such the Conversion Date for such conversion.

(c) Each share of Common Stock issued upon conversion of any Notes that are Restricted Notes shall be subject to the Restricted Stock Legend as set forth in Section 3.06 .

Section 7.03 Settlement upon Conversion Into Common Stock .

(a) The type and amount of consideration due in respect of each $1,000 principal amount of a Note to be converted will be a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion and an Interest Make-Whole Payment, if applicable; provided , however , that, subject to Section 7.03(e), in lieu of issuing or delivering any fraction of any share of Common Stock, the Company will instead either, at the Company ’ s option, (I) pay cash in an amount equal to the product of (x) such fraction and (y) the Last Reported Sale Price per share of Common Stock on such Conversion Date; or (II) deliver an additional whole share of Common Stock.

(b) Subject to Section 7.05 , the Company will deliver the consideration (and settlement of any Interest Make-Whole Payment, if applicable) due upon conversion of any Note on or before the second (2nd) Business Day after the Conversion Date for such conversion.

(c) Subject to Section 7.03(d), upon conversion, Holders shall not receive any separate cash payment for accrued and unpaid interest.

(d) If the Conversion Date for any Note is after a Regular Record Date and before the next Interest Payment Date, then (i) the Holder(s) of such Note at the Close of Business on such Regular Record Date will receive, on such Interest Payment Date, the interest that would have accrued on such Note to, and been payable on,

22

such Interest Payment Date notwithstanding the conversion; and (ii) such Note, when surrendered for conversion, must be accompanied by funds equal to the amount of such interest; provided , however , that no such payment need be made (A) for conversions whose Conversion Date occurs following the Regular Record Date immediately preceding the Maturity Date, (B) for conversions whose Conversion Date occurs following a Regular Record Date immediately preceding a Redemption Date, (C) for conversions in respect of which an Interest Make-Whole Payment is payable upon conversion (or would have been payable but for the conversion occurring following the Regular Record Date preceding the last Interest Payment Date); or (D) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Note.

(e) If multiple Notes shall be surrendered for conversion with the same Conversion Date by the same Holder, the number of full shares which shall be issuable upon such conversion (and the number of fractional shares, if any, for which cash shall be delivered) and Interest Make-Whole Payment, if applicable, shall be computed on the basis of the aggregate Principal Amount of such Notes to be so converted.

(f) By delivery to the Holder of the consideration due upon conversion of any Note, the Company will be deemed to satisfy in full its obligation to pay the Principal Amount of the Notes and all accrued and unpaid interest to, but excluding, the Conversion Date. Upon conversion of the Notes, all accrued and unpaid interest to, but excluding, the Conversion Date will be deemed to be paid in full rather than canceled, extinguished or forfeited, subject to Section 7.03(d).

(g) Shares of Common Stock issued upon a conversion (including pursuant to the Interest Make-Whole Payment) shall be delivered pursuant to a book entry with the transfer agent for the Common Stock, and in no event shall paper certificates be issued or delivered, except with the consent of the Holder receiving the same.

Section 7.04 Adjustment of Conversion Rate . The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs as described below, except that the Company will not make any adjustment to the Conversion Rate if Holders of Notes participate, at the same time and on the same terms as holders of shares of Common Stock, solely as a result of holding the Notes, in any of the transactions described in this Section 7.04 , without having to convert their Notes, as if each Holder held, on the applicable Record Date or effective date, a number of shares of Common Stock equal to the Conversion Rate in effect on such Record Date or effective date, multiplied by the Principal Amount of Notes held by such Holder, divided by $1,000.

(a) If the Company issues solely shares of Common Stock as a dividend or distribution on all or substantially all of the shares of the Common Stock, or the Company effects a share split or share combination applicable to all shares of the Common Stock (in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section 7.05 will apply), the Conversion Rate will be adjusted based on the following formula:

23

If any dividend, distribution, share split or share combination of the type described in this Section 7.04(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 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) If the Company distributes, to all or substantially all holders of shares of Common Stock, any rights, options or warrants entitling such holders for a period of not more than sixty (60) calendar days after the Record Date of 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 per share of Common Stock over the ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately preceding the date of announcement of such distribution, the Conversion Rate will be increased based on the following formula:

The foregoing increase in the Conversion Rate shall be successively made whenever any such rights, options or warrants are distributed. If such rights, options or warrants are not so distributed, the Conversion Rate will be immediately readjusted to the Conversion Rate that would then be in effect if such Record Date for such distribution had not been fixed. In addition, to the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised), the Conversion Rate shall be immediately readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate made for the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise of such rights, option or warrants.

In determining whether any rights, options or warrants entitle the holders of shares of Common Stock to subscribe for or purchase shares of Common Stock at less than such average of the Last Reported Sale Prices, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable upon exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

24

(c)

(i) If the Company distributes shares of its Capital Stock, evidences of its Indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company ’ s Capital Stock or other securities (the “ Distributed Property ” ), to all or substantially all holders of shares of Common Stock, excluding:

(A) dividends, distributions, rights, options or warrants for which an adjustment is required (or would be required without regard to Section 7.04(h)) pursuant to Section 7.04(a) or Section 7.04(b);

(B) dividends or distributions paid exclusively in cash for which an adjustment is required (or would be required without regard to Section 7.04(h)) pursuant to Section 7.04(d);

(C) rights issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 7.10 ;

(D) Spin-Offs for which an adjustment is required (or would be required without regard to Section 7.04(h)) pursuant to Section 7.04(c)(ii); and

(E) a distribution solely pursuant to a Common Stock Change Event, as to which the provisions set forth in Section 7.05 will apply,

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

No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. If such distribution is not so paid or made, or such rights, options or warrants are not exercised before their expiration (including as a result of being redeemed or terminated), the Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the distribution, if any, actually made or paid or on the basis of the distribution of only such rights, options or warrants, if any, that were actually exercised, if at all. Notwithstanding the foregoing, if “ FMV ” (as defined above) is equal to or greater than “ SP ” (as defined above), then, in lieu of the foregoing increase, each Holder shall receive, in respect of each $1,000 principal amount of Notes that it held on the Record Date for such distribution, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, without having to convert its Notes, the amount and kind of Distributed Property such Holder would have received if such Holder owned, on such Record Date, a number of shares of Common Stock equal to the Conversion Rate in effect on such Record Date. If the Company determines the “ FMV ” (as defined above) of any distribution for purposes of this Section 7.04(c)(i) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the same period used in computing the average Last Reported Sale Prices per share of Common Stock referred to above.

25

(ii) With respect to an adjustment pursuant to this Section 7.04(c) where there has been a payment of a dividend or other distribution on all or substantially all shares of the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary, or other business unit or Affiliate, of the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the transaction) on a U.S. or non-U.S. securities exchange (as determined by the Company) (a “ Spin-Off ” ), the Conversion Rate will be increased based on the following formula:

The adjustment to the Conversion Rate pursuant to this Section 7.04(d) will be calculated as of the Close of Business on the last Trading Day of the Spin-Off Valuation Period but will be given effect immediately after the Close of Business on the Record Date for the Spin-Off, with retroactive effect. If a Note is converted and the Conversion Date occurs during the Spin-Off Valuation Period, then, notwithstanding anything to the contrary, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Spin-Off Valuation Period. To the extent any dividend or distribution that constitutes a Spin-Off is declared but not paid or made, the Conversion Rate shall be immediately readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid.

(d) If any cash dividend or distribution is paid or made to all or substantially all holders of shares of Common Stock, the Conversion Rate shall be increased based on the following formula:

26

No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. To the extent such dividend or distribution is declared but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if any, actually made or paid. Notwithstanding the foregoing, if “ C ” (as defined above) is equal to or greater than “ SP ” (as defined above), then, in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes that it held on the Record Date for such distribution, at the same time and upon the same terms as holders of shares of the Common Stock, without having to convert its Notes, the amount of cash that such Holder would have received if such Holder owned, on such Record Date, a number of shares of Common Stock equal to the Conversion Rate on such Record Date.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for shares of Common Stock, to the extent that the value (determined as of the Expiration Time by the Company) of the cash and any other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Prices per share of Common Stock on the Trading Day immediately after the last date (the “ Expiration Date ” ) on which tenders or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased based on the following formula:

where,

The adjustment to the Conversion Rate pursuant to this Section 7.04(e) will be calculated as of the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period but will be given effect immediately after the Expiration Time, with retroactive effect. If a Note is converted and the Conversion Date occurs during the Tender/Exchange Offer Valuation Period, then, notwithstanding anything to the contrary, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Tender/Exchange Offer Valuation Period. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate.

If the Company is obligated to purchase shares of Common Stock pursuant to any such tender or exchange offer, but the Company is ultimately prevented by applicable law from effecting all or any portion of such purchases or all such purchases are rescinded, the Conversion Rate shall immediately be readjusted to the Conversion Rate that would then be in effect if such tender or exchange offer had not been made or had been made only in respect of the purchases that had been effected.

27

(f) In addition to those Conversion Rate adjustments required by Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) and 7.04(e) , and to the extent permitted by applicable law and subject to the applicable rules of The Nasdaq Global Market (including Market Rule 5635) and, if applicable, any securities exchange on which the Company ’ s securities are then listed, the Company from time to time may (but is not required to) (i) increase the Conversion Rate by any amount for a period of at least twenty (20) Business Days if the Board of Directors determines that such increase would be in the Company ’ s best interest and (ii) increase the Conversion Rate to avoid or diminish any income tax to holders of shares of Common Stock or rights to purchase shares of Common Stock in connection with any dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event.

(g) Notwithstanding anything to the contrary, the Conversion Rate will not be adjusted:

(i) the sale of shares of Common Stock for a purchase price that is less than the market price per share of Common Stock or less than the Conversion Price;

(ii) 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;

(iii) upon the entry into any share repurchase program by the Company, including any accelerated share repurchase transaction or other share repurchase transaction effected through the use of derivatives;

(iv) 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 its Subsidiaries;

(v) 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 (iv) above and outstanding as of the date the Notes were first issued, except as set forth in Section 7.10 ;

(vi) for a third-party tender offer by any party other than a tender offer by one or more of the Company’s Subsidiaries as described in Section 7.04(e);

(vii) upon the repurchase of any shares of the Common Stock pursuant to an open market share repurchase program or other buy-back transaction, including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives, or other buy-back transaction, that is not a tender offer or exchange offer of the kind described in Section 7.04(e);

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

(ix) for accrued and unpaid interest, if any, on the Notes.

(h) Adjustments to the Conversion Rate under this ARTICLE 7 shall be calculated to the nearest cent or to the nearest one-ten thousandth (1/10,000th) of a share of Common Stock. Notwithstanding anything to the contrary in Section 7.04 , no adjustment shall be made to the Conversion Rate unless such adjustment would require a change of at least one percent (1%) in the Conversion Rate, and any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any future adjustment; provided , however , that upon any conversion of the Notes, the Company shall give effect to all adjustments that Company otherwise has deferred pursuant to this sentence, and those adjustments will no longer be carried forward and taken into account in any future adjustment.

(i) After any adjustment to the Conversion Rate pursuant hereto, the Company shall prepare and send to Holders, within 20 days of the effective date of such adjustment, a notice of such adjustment setting forth the adjusted Conversion Rate and the date on which each adjustment became effective. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

28

(j) For purposes of this Section 7.04 , the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company, so long as the Company does not pay any dividend or make any distribution on such shares, but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 7.05 Effect of Reclassification, Consolidation, Merger, Sale, Etc . In the case of (i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination, any stock dividends or any change in par value or from a par value to no par value or from no par value to a par value), (ii) any consolidation, merger or combination involving the Company, (iii) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, or (iv) any statutory share exchange, 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, other securities or other property or assets (including cash or any combination thereof) (any such event, a “ Common Stock Change Event , ” and such stock, securities, property or assets, the “ Reference Property , ” and the amount and kind of Reference Property that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without giving effect to any arrangement not to issue fractional shares of securities or other property), a “ Reference Property Unit ” ), then, notwithstanding anything to the contrary,

(a) at the effective time of such Common Stock Change Event, (1) the consideration due upon conversion of any Note will be determined in the same manner as if each reference to any number of shares of Common Stock in this ARTICLE 7 (or in any related definitions) were instead a reference to the same number of Reference Property Units; and for (2) purposes of the definition of “ Fundamental Change ” and “ Make-Whole Fundamental Change, ” the term “ Common Stock ” will be deemed to mean the Common Equity, if any, forming part of such Reference Property;

(b) if such Reference Property Unit consists entirely of cash, then, in respect of all conversions whose Conversion Date occurs on or after the effective date of such Common Stock Change Event, the Company will pay the cash due upon such conversions no later than the second (2nd) Business Day after the relevant Conversion Date;

(c) 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);

(d) the Company shall promptly execute, and the Holders shall counter-sign, a supplemental agreement pursuant to ARTICLE 13 that (1) will provide for subsequent conversions of Notes in the manner set forth in this Section 7.05 ; (2) will provide for subsequent adjustments to the Conversion Rate pursuant to Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d), 7.04(e) and 7.07 in a manner consistent with this Section 7.05 ; and (3) may contain such other provisions as (i) the Company in good faith determines are appropriate to preserve the economic interests of the Holders and to give effect to the provisions of this Section 7.05 and (ii) to which Holders of at least a majority of the aggregate principal amount of Notes then outstanding reasonably agree.

If such Common Stock Change Event causes the Common Stock to be converted into, or exchanged for, or represent solely the right to receive, more than a single type of consideration (determined based in part upon any form of shareholder election), the composition of the Reference Property Unit will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election. The Company shall notify Holders of the Notes of such weighted average as soon as practicable after such determination is made.

The Company shall not become a party to any Common Stock Change Event unless its terms are consistent with this Section 7.05 . None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes as set forth in Section 7.01 and Section 7.02 prior to the effective date of such Common Stock Change Event.

Section 7.06 Adjustments of Prices . Whenever any provision of this Agreement requires a calculation of the Last Reported Sale Prices, or a function thereof, over a span of multiple days, the Company may make adjustments determined by the Company or its agents to account for any adjustment to the Conversion Rate that becomes

29

effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date, Record Date, effective date or Expiration Date, as the case may be, of the event occurs, at any time during the period during which such calculations are based.

Section 7.07 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes .

(a) If a Make-Whole Fundamental Change occurs or becomes effective prior to the Maturity Date and a Holder elects to convert any of its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Conversion Rate for such Notes by a number of additional shares of Common Stock (the “ Additional Shares ” ), as set forth below. A conversion of Notes shall be deemed for these purposes to be “ in connection with ” such Make-Whole Fundamental Change if the Conversion Date for such conversion occurs on or after the effective date of the Make-Whole Fundamental Change and on or before the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, if such Make-Whole Fundamental Change is not a Fundamental Change, on or before the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “ Make-Whole Fundamental Change Period ” ). Notwithstanding anything to the contrary, in no event will the Conversion Rate applicable to the conversion of any Note in connection with a Make-Whole Fundamental Change be increased pursuant to this Section 7.07 if such Make-Whole Fundamental Change constitutes a Fundamental Change pursuant to clause (a) of the definition of such term where the “ person ” or “ group ” referred to in such clause is, or includes, the Holder or beneficial owner of such Note or any Affiliate thereof.

(b) If a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, constitutes a Common Stock Change Event for which the Reference Property is composed entirely of cash, then, for any conversion of Notes with a Conversion Date following the effective date of such Make-Whole Fundamental Change, the consideration due upon such shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the applicable Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. The Company shall notify the Holders of Notes of the effective date of any Make-Whole Fundamental Change no later than five (5) Business Days after such effective date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table in Section 7.07(e), based on the date on which the Make-Whole Fundamental Change occurs or becomes effective and the price (the “ Stock Price ” ) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices per share of Common Stock over the five (5) Trading Days ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(d) The Stock Prices set forth in the column headings of the table in Section 7.07(e) shall be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant to Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) or 7.04(e). 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 immediately prior to such 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 set forth in the table below shall be adjusted in the same manner as, and at the same time and for the same events for which, the Conversion Rate is adjusted pursuant to Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) or 7.04(e).

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 7.07 for each Stock Price and effective date set forth below:

If such effective date or Stock Price are not set forth in the table above, then:

(i) if such Stock Price is between two Stock Prices in the table above or the effective date is between two effective dates in the table above, then the number of Additional Shares will be determined by a straight-line interpolation between the numbers of Additional Shares set forth for the higher and lower Stock Prices in the table and the earlier and later effective dates in the table above, as applicable, based on a 365 - or 366-day year, as applicable;

(ii) if the Stock Price is greater than $1.23 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above are adjusted pursuant to Section 7.07(d)), then no Additional Shares will be added to the Conversion Rate; and

(iii) if the Stock Price is less than $5.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above are adjusted pursuant to Section 7.07(d)), then no Additional Shares will be added to the Conversion Rate.

Notwithstanding anything to the contrary, in no event will the Conversion Rate be increased pursuant to this Section 7.07 to an amount that exceeds 813.0007 shares of Common Stock per $1,000 principal amount of Notes, which amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Rate is required to be adjusted pursuant to Sections 7.04(a), 7.04(b), 7.04(c), 7.04(d) or 7.04(e). Notwithstanding the foregoing, if the Conversion Rate is increased for Notes converted in connection with a Make-Whole Fundamental Change, then the Holder of such converted Notes will not receive the Interest Make-Whole Payment with respect to such converted Notes.

Section 7.08 Taxes on Shares Issued . Any issue of shares of Common Stock upon the conversion of Notes shall be made without charge to the converting Holder for any documentary, transfer, stamp or any similar tax in respect of the issue thereof, and the Company shall pay any and all documentary, stamp or similar issue or transfer taxes or duties that may be payable in respect of the issue or delivery of shares of Common Stock, if any, upon conversion of Notes pursuant hereto. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of shares in any name other than that of the Holder of any Notes converted, and, in addition to any other requirements or conditions set forth herein, the Company shall not be required to issue or deliver any such shares unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 7.09 Reservation of Shares; Listing . The Company shall at all times provide, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the Notes from time to time as such Notes are presented for conversion (assuming that, at the time of the computation of such number of shares, all such Notes would be held by a single Holder). The Company will use its best efforts to cause all shares of Common Stock issued upon conversion of the Notes to be listed on any U.S. securities exchange upon which the Common Stock is then listed.

31

Section 7.10 Shareholder Rights Plan . Each share of Common Stock, if any, issued upon conversion of Notes pursuant to this ARTICLE 7 shall be entitled to receive the appropriate number of rights, if any, and the certificates, if any, representing such shares shall bear such legends, if any, in each case as may be provided by the terms of any then-effective shareholder rights agreement adopted by the Company, as any such agreement may be amended from time to time. Notwithstanding the foregoing, if, prior to any conversion of any Notes, such rights have separated from the Common Stock in accordance with the provisions of the applicable shareholder rights agreement, then the Conversion Rate shall be adjusted at the time of separation as if the Company had distributed, to all holders of the Common Stock, Distributed Property as described in Section 7.04(c) , subject to readjustment in the event of the expiration, termination or redemption of such rights. Unless and until such rights have so separated, no adjustment to the Conversion Rate will be made pursuant to Section 7.04(c) on account of such rights.

Section 7.11 Company Determination Final . Any determination that the Company or the Board of Directors contemplated pursuant to this ARTICLE 7 shall be conclusive if made in good faith and in accordance with the provisions of this ARTICLE 7 , absent manifest error.

Section 7.12 Exchange in Lieu of Conversion . Notwithstanding anything to the contrary in this ARTICLE 7 , and subject to the terms of this Section 7.12 , if a Note is to be converted, the Company may elect to arrange to have such Note exchanged in lieu of conversion by a financial institution designated by the Company. To make such election, the Company must provide written notice of such election to the Holder of such Note before the Close of Business on the Business Day immediately after the Conversion Date for such Note. If the Company has made such election, then:

(a) no later than the Business Day immediately after such Conversion Date, the Company must deliver such Note, together with delivery instructions for the consideration due upon such conversion, to a financial institution designated by the Company that has agreed to deliver such consideration in the manner and at the time the Company would have had to deliver the same pursuant to this ARTICLE 7 ; and

(b) such Note will not cease to be outstanding by reason of such exchange in lieu of conversion;

provided , however , that if such financial institution does not accept such Note or fails to timely deliver such consideration, then the Company will be responsible for delivering such consideration in the manner and at the time provided in this ARTICLE 7 as if the Company had not elected to make an exchange in lieu of conversion.

Section 7.13 .  Limits on Issuance of Shares of Common Stock upon Conversion.

(a) Notwithstanding anything to the contrary in this Agreement, no Person will be entitled to receive any shares of Common Stock otherwise deliverable upon conversion of the Notes to the extent, but only to the extent, that such receipt would cause such Person to become, directly or indirectly, a “Beneficial Owner” (as defined below) of more than 19.99% of the shares of the Common Stock outstanding at such time (such restrictions, as in effect from time to time, the “ General Beneficial Ownership Limits ”). In addition, a Holder at its option may elect a limit on beneficial ownership as to such Holder (but not as to any other Holder) that is less than or equal to any General Beneficial Ownership Limit then applicable to such Holder upon written notice delivered to the Company at least sixty one (61) days prior to the date of effectiveness of such beneficial ownership limit, specifying the percentage of shares of Common Stock outstanding for the beneficial ownership limit that shall apply to such Holder (such beneficial ownership limit, a “ Holder Beneficial Ownership Limit ” and together with the General Beneficial Ownership Limits, the “ Beneficial Ownership Limits ”). Any such reduction in the Beneficial Ownership Limit by a Holder as to such Holder may be revoked by such Holder only by notice given sixty one (61) days prior to the date such revocation shall become effective. The Company shall otherwise deliver any consideration due in respect of any conversion of the Notes as set forth in Section 7.03. As of the Closing Date, the Investor has elected a Holder Beneficial Ownership Limit applicable to the Investor and its Affiliates on an aggregate basis of 9.99%.

(b) Any purported delivery of shares of Common Stock upon conversion of the Notes shall be void and have no effect to the extent, but only to the extent, that such delivery would result in any Person becoming the Beneficial Owner of shares of Common Stock outstanding at such time in excess of the Beneficial Ownership Limits applicable to such Person.

32

(c) Unless the Company shall have waived the General Beneficial Ownership Limits as set forth in subsection (e) below, and there is no Holder Beneficial Ownership Limit applicable to a Holder, when such Holder tenders Notes for conversion, that Holder must provide a certification to the Company as to whether the Person (or Persons) receiving shares of the Common Stock upon conversion is, or would, as a result of such conversion, become the Beneficial Owner of shares of Common Stock in excess of any Beneficial Ownership Limit then applicable to such Person (or Persons).

(d) If any delivery of shares of Common Stock otherwise owed to any Person (or Persons) upon conversion of the Notes is not made, in whole or in part, as a result of any applicable Beneficial Ownership Limit, the relevant Holder may either:

(i) request the return of the Notes surrendered by such Holder for conversion in writing, after which the Company shall deliver such Notes to such Holder within three (3) Trading Days after receipt of such written request; or

(ii) certify to the Company that the Person (or Persons) receiving shares of the Common Stock upon conversion is not, and would not, as a result of such conversion, become the Beneficial Owner of shares of the Common Stock outstanding at such time in excess of any applicable Beneficial Ownership Limit, after which the Company shall deliver any such shares of Common Stock withheld on account of such applicable Beneficial Ownership Limits by the later of (x) the date such shares would otherwise have been due to such Person (or Persons) pursuant to Section 7.03 and (ii) two Trading Days after receipt of such certification; provided , however , until such time as the affected Holder gives such notice, no Person shall be deemed to be the stockholder of record with respect to the shares of Common Stock otherwise deliverable upon conversion in excess of any applicable beneficial ownership limit in accordance with Section 7.02. Upon delivery of such notice, the provisions set forth in Section 7.03 and Section 7.02 shall apply to the shares of Common Stock to be delivered pursuant to such notice.

(e) The Company may, at its option with the approval of the Board of Directors and subject to the applicable listing standards of The Nasdaq Stock Market LLC (or any other stock exchange where any securities of the Company are then listed), waive the General Beneficial Ownership Limits (as to a particular Person or as to all Persons).  In the event that the Company exercises its right to waive any General Beneficial Ownership Limit to all Persons, the Company shall deliver or cause to be delivered to each Holder 61 days prior to the effective waiver date an irrevocable notice stating that as of an effective date specified therein, the Company waives any restrictions that limit a Holder from converting its Notes in the event that such Holder is, or would, as a result of a conversion of Notes, become, a Beneficial Owner of shares of Common Stock in excess of such General Beneficial Ownership Limit. Any such waiver of a General Beneficial Ownership Limit would not effect a waiver of any Holder Beneficial Ownership Limit.

For purposes of this Section 7.13 only, a Person shall be deemed the “ Beneficial Owner ” of and shall be deemed to beneficially own any shares of Common Stock that such Person or any of such person’s Affiliates or Associates is deemed to beneficially own, together with any shares of Common Stock beneficially owned by any other Persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act. Subject to the following proviso, for purposes of the this Section 7.13, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder as in effect on the date of this Indenture; provided that (x) the number of shares of Common Stock beneficially owned by such Person and its Affiliates and Associates and any other Persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act shall include the number of shares of Common Stock issuable upon exercise or conversion of any of the Company’s securities or rights to acquire Common Stock, whether or not such securities or rights are currently exercisable or convertible or are exercisable or convertible only after the passage of time (including the number of shares of Common Stock issuable upon conversion of the Notes in respect of which the beneficial ownership determination is being made) and (y) the number of shares of Common Stock outstanding at such time shall exclude the number of shares of Common Stock that would be issuable upon (A) conversion of the remaining, unconverted portion of any Notes beneficially owned by such Person or any of its Affiliates or Associates and any other Persons whose beneficial ownership would be aggregated with such person for purposes of Section 13(d) of the Exchange Act and (B) exercise or conversion of the unexercised or unconverted portion of any of the Company’s other securities subject to

33

a limitation on conversion or exercise analogous to the limitations contained in this Section 7.13 beneficially owned by such Person or any of its Affiliates or Associates and any other Persons whose beneficial ownership would be aggregated with such Person for purposes of Section 13(d) of the Exchange Act.

(a) Notwithstanding anything to the contrary, the Company may elect that the sole remedy for any Event of Default (a “ Reporting Event of Default ” ) pursuant to Section 9.01(e) arising from the Company ’ s failure to comply with Section 4.03 will, for each of the first one hundred and eighty (180) calendar days on which a Reporting Event of Default has occurred and is continuing, consist exclusively of the accrual of Special Interest on the Notes. If the Company has made such an election, then the Notes will be subject to acceleration pursuant to Section 9.03 on account of the relevant Reporting Event of Default from, and including, the one hundred and eighty first (181st) calendar day on which a Reporting Event of Default has occurred and is continuing or if the Company fails to pay any accrued and unpaid Special Interest when due.

(b) Any Special Interest that accrues on a Note pursuant to Section 9.02(a) will be payable on the same dates and in the same manner as the Stated Interest on such Note and will accrue at a rate per annum equal to (i) one quarter of one percent (0.25%) of the principal amount thereof for the first one hundred eighty (180) calendar days following the Reporting Event of Default and (ii) one half of one percent (0.50%) thereafter until such Reporting Event of Default shall have been cured; provided , however , that in no event will Special Interest accrue on any day on a Note at a combined rate per annum that exceeds one-half of one percent (0.50%). For the avoidance of doubt, any Special Interest that accrues on a Note will be in addition to the Stated Interest that accrues on such Note.

(c) To make the election set forth in Section 9.02(a), the Company must send to the Holders, before the date on which each Reporting Event of Default first occurs, a written notice that states that the Company is electing that the sole remedy for such Reporting Event of Default consist of the accrual of Special Interest.

Section 9.03 Acceleration of Maturity; Waiver of Past Defaults and Rescission .

(a) If an Event of Default occurs and is continuing, then and in every such case the Holders of at least a majority in the aggregate Principal Amount of the outstanding Notes may declare 100% of the Principal Amount plus accrued and unpaid interest on all the outstanding Notes to be due and payable immediately, by a notice in writing to the Company (and to the other Holders if given by any Holder), and upon any such declaration, such Principal Amount and accrued and unpaid interest shall become immediately due and payable.

Notwithstanding the foregoing, in the case of an Event of Default specified in Section 9.01(h) or Section 9.01(i) with respect to the Company (and not solely with respect to any Significant Subsidiaries of the Company), 100% of the Principal Amount plus accrued and unpaid interest on all outstanding Notes will automatically become due and payable without any declaration or other act on the part of any Holder.

(b) The Holders of a majority in aggregate Principal Amount of the outstanding Notes, by written notice to the Company and each other Holder, may (x) waive any past Default and its consequences and (y) at any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained, rescind any such acceleration with respect to the Notes and its consequences, except, in each case, with respect to a Default described in Section 9.01(a) , Section 9.01(b) or Section 9.01(d) , or in respect of a covenant or provision hereof which under Article 13 cannot be modified or amended without the consent of the Holder of each outstanding Note affected, if:

(i) such rescission will not conflict with any judgment or decree of a court of competent jurisdiction; and

(ii) all existing Events of Default (except the non-payment of Principal Amount and accrued and unpaid interest that has become due solely because of such acceleration) have been cured or waived.

38

Upon any such waiver, the Default which has been waived shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of the Agreement; but no such waiver shall extend to any subsequent or other Default or impair any right consequent.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 9.04 Unconditional Right of Holders to Receive Payment and Convert . Notwithstanding any other provision of this Agreement, the right of any Holder to receive payment of the Principal Amount (including interest in respect of the Notes held by such Holder, on or after the respective due dates expressed in the Notes or otherwise, as applicable), any accrued and unpaid interest and to convert the Notes in accordance with ARTICLE 7 , or to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, shall not be impaired or affected without the consent of such Holder.

Section 9.05 Restoration of Rights and Remedies .

Notwithstanding the foregoing, promptly following the Closing Date, the Company shall (subject to the terms and conditions of this Article 11, including for the avoidance of doubt, the Blackout Periods to the extent provided in Section 11.04 ), file with the Commission a registration statement on Form S-3 (or such other form as may be applicable for the resale of the Registrable Securities) with respect to the maximum number of Registrable Securities issuable upon conversion of the Notes (including, in connection with any Make-Whole Fundamental Change or Interest Make-Whole Payment, subject to the proviso below) purchased by the Investor (which shall be deemed to be a “Requesting Holder” for the purposes of this Article 11) on the Closing Date to cover a registered sale of such Registrable Securities for cash by the Investor in a Shelf Offering; provided , however , that if the Commission shall not allow such maximum number of Registrable Securities issuable upon conversion of the Notes, then the Company shall only be obligated to register on such registration statement the offer and sale of the maximum number of Registrable Securities as the Commission shall permit, and the Company shall file such additional registration statement or registration statements for the remaining number of Registrable Securities thereafter at the request of the Investor if and when the registration of such additional Registrable Securities is permitted by the Commission .

Section 11.03 Obligations of the Company . At such time as the Company is obligated to file a Registration Statement with the Commission pursuant to this Article 11, the Company shall also be obligated to use commercially reasonable efforts to take the following actions:

(a) promptly prepare and file with the Commission such amendments and supplements to any Registration Statement filed and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective, in the case of an Underwritten Offering, until the completion of such offering, and in the case of a Shelf Offering, until such time as the Registrable Securities of the Holders subject to such registration shall have been sold pursuant thereto or such Registrable Securities have been, or could be without restriction, sold pursuant to Rule 144 or another available exemption from the registration requirement of the Securities Act;

The Company will use all reasonable efforts to amend or supplement such prospectus or Registration Statement or any document incorporated or deemed to be incorporated therein by reference, or file any other required document, as applicable, as soon as practicable in order to cause such prospectus to not include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they are made, not misleading;

(g) notify each Holder of Registrable Securities covered by such Registration Statement and the underwriter(s), if any: (i) when the prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to the Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; and (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;

(h) furnish, in the case of any Underwritten Offering of Registrable Securities pursuant to this Article 11, at the request of the underwriter(s), on the date that such Registrable Securities are delivered to the underwriters, the letter (including any “ bring-downs ” related thereto) from the independent registered accounting firm of the Company issued pursuant to the underwriting agreement relating to such Underwritten Offering;

(i) cause all Registrable Securities sold pursuant to a Registration Statement to be listed on the stock exchange, if any, on which the Company ’ s Common Stock is then listed;

(j) make such representations and warranties to the underwriter(s), if any, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings by selling stockholders of comparable size and confirm the accuracy of the same if and when reasonable and customarily requested by such underwriters, and matters relating to the compliance of the Registration Statement and the prospectus with the Securities Act;

42

disbursements of a single counsel (together with no more than one local counsel) for the Requesting Holders as designated in writing to the Company by Requesting Holders holding a majority of the Registrable Securities or the Investor , as applicable (such counsel(s), the “ Designated Counsel ” ); provided , however , that the Company will in no event bear, and each Holder shall instead bear, the cost of Selling Expenses with respect to such Holder ’ s Registrable Securities, if any, in connection with the offering of the Registrable Securities pursuant to the Registration Statement, and each Holder and any other Person participating in such offering shall bear all such specified Selling Expenses pro rata among each other on the basis of the number of Registrable Securities which have been registered; provided , further , the fees and disbursements of any Designated Counsel to be borne by the Company will in no event exceed, in the aggregate, twenty thousand dollars ($20,000) per Underwritten Offering or, without duplication, per registration statement filed pursuant to Section 11.01 in which any Requesting Holder is named as a selling stockholder.

(l) in the event of the issuance of any stop order suspending the effectiveness of a Registration Statement, or of any order suspending or preventing the use of any related prospectus or suspending the qualification of any Registrable Securities included in such Registration Statement for sale in any jurisdiction, use all reasonable efforts to obtain the withdrawal of such order as soon as practicable; and

(a) The Company will indemnify each Requesting Holder, each of its officers, directors, partners, employees and agents, and each Person controlling such Holder (within the meaning of Section 15 of the Securities Act), with respect to any registration, qualification or sale which has been effected pursuant to this Article 11, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on (i) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement filed pursuant to this ARTICLE 11 , or related prospectus, or any amendment or supplement thereto, incident to any such registration, qualification or sale, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any such prospectus, in the light of the circumstances in which they were made) not misleading, or (ii) any violation (or alleged violation) by the Company of the Securities Act, the Exchange Act or the securities or similar laws of any state or other jurisdiction in which Registrable Securities are sold, and the Company will reimburse or pay for the account of such Requesting Holder, officer, director, partner, employee, agent or controlling person, for any legal and any other expenses reasonably incurred (as and when incurred) in connection with investigating, preparing the defense of or defending any such claim, loss, damage, liability or action.

(b) To the extent permitted by law, each Requesting Holder, severally and not jointly, will, if securities held by such Requesting Holder, are included in the securities as to which a registration, qualification or sale pursuant to this ARTICLE 11 is effected, indemnify the Company, each of its officers, directors, partners, employees and agents, each Person who controls the Company (within the meaning of Section 15 of the Securities Act), and any other Person participating in such registration, each of its officers and directors and each Person controlling (within the meaning of Section 15 of the Securities Act) such Person participating in such registration, against all expenses, claims, losses, damages or liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement filed pursuant to

44

this ARTICLE 11 , or related prospectus, or any amendment or supplement thereto, incident to any such registration, qualification or sale, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any such prospectus, in the light of the circumstances in which they were made) not misleading, and the Company will reimburse or pay for the account of the Company or such Person, officer, director, partner, employee, agent or controlling person, for any legal and any other expenses reasonably incurred (as and when incurred) in connection with investigating, preparing the defense of or defending any such claim, loss, damage, liability or action; provided , however , that in no event shall any Requesting Holder have any liability under this Section 11.07(b) in any such case except to the extent that any such claim, loss, damage, liability or action arises out of or is based on any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information furnished to the Company by such Requesting Holder.

(c) Each indemnified party under this Section 11.07 shall give notice to the indemnifying party promptly after such indemnified party has actual knowledge of any claim as to which indemnity may be sought and shall permit the indemnifying party to assume the defense of any such claim or any litigation resulting therefrom; provided , however , that counsel for the indemnifying party, who shall conduct the defense of such claim or litigation, shall be approved by the indemnified party (which approval shall not unreasonably be withheld), and the indemnified party may participate in such defense at such indemnified party ’ s expense; provided , further , that the failure of any indemnified party to give notice as provided above shall not relieve the indemnifying party of its obligations under this agreement except to the extent that the failure to give such notice is materially prejudicial to an indemnifying party ’ s ability to defend such action. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The obligations of the Company and the Requesting Holders under this Section 11.07 shall survive the completion of any offering of Registrable Securities in a Registration Statement pursuant to this Agreement.

(e) If a claim for indemnification under Section 11.07(a) or 11.07(b) is available by its terms but is held by a court of competent jurisdiction to be unavailable or insufficient to hold harmless an indemnified party, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of any such claim, loss, damage, liability or action that otherwise would have been indemnified under Section 11.07(a) or 11.07(b), as the case may be, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other, in connection with the statements or omissions that resulted in such claim, loss, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties ’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount of such claim, loss, damage, liability or action subject to this Section 11.07(e) shall be deemed to include any reasonable legal or other expenses incurred by such indemnified party in connection with investigating or defending any such claim, loss, damage, liability or action (which shall be limited as provided in Section 11.07(c) if the indemnifying party has assumed the defense of any such action in accordance with the provisions thereof). Notwithstanding the foregoing in this Section 11.07(e), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Promptly after receipt by an indemnified party of notice of the commencement or threatened commencement of any claims for which a claim for contribution may be made against an indemnifying party under this Section 11.07(e) and if a notice for indemnification has not been otherwise given under this Section 11.07 , such indemnified party shall give written notice thereof in the manner set forth hereunder for a claim for indemnification to the indemnifying party; provided , however , that the failure to so notify the indemnifying party shall not relieve it of any obligation to provide contribution hereunder except to the extent that the indemnifying party ’ s ability to defend such action is materially prejudiced by the failure to give such timely notice. The parties acknowledge that determining contribution pursuant to this Section 11.07(e) by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 11.07(e) would not be just or equitable. For the avoidance of doubt, if indemnification is available under Section 11.07(a) or 11.07(b), the indemnifying

45

parties shall indemnify each indemnified party to the fullest extent provided in Section 11.07(a) or 11.07(b) without regard to the relative fault of said indemnifying party or indemnified party or any other equitable consideration provided for in this Section 11.07(e) .

Section 11.08 Effectiveness; Termination; Survival . The provisions of Article 11 (other than Section 11.07 ) shall survive the discharge or termination of this Agreement until the earlier of (a) the time when no Registrable Securities are outstanding; and (ii) four (4) years after the Maturity Date. The provisions of Section 11.07 shall survive the discharge or termination of this Agreement indefinitely.
