Warrant No.:

Date of Issuance: April 3, 2019 (“ Issuance Date ”)

Endologix, Inc., a Delaware corporation (the “ Company ”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [BUYER], the registered holder hereof or its permitted assigns (the “ Holder ”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon exercise of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “ Warrant ”), at any time or times on or after April 3, 2019 (the “ Initial Exercisability Date ”), but not after 11:59 p.m., New York time, on the Expiration Date (as defined below),                          (subject to adjustment as provided herein) fully paid and non-assessable shares of Common Stock (as defined below) (the “ Warrant Shares ”, and such number of Warrant Shares, the “ Warrant Number ”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 17. This Warrant is one of the Warrants to Purchase Common Stock (the “ Registered Warrants ”) issued pursuant to (i) Section 1 of that certain Purchase Agreement, dated as of March 31, 2019 (the “ Subscription Date ”), by and among the Company and the investors (the “ Buyers ”) referred to therein, as amended from time to time (the “ Securities Purchase Agreement ”) and (ii) and (ii) the Company’s Registration Statement on Form S-3 (File number 333-225320) (the “ Registration Statement ”). The Aggregate Exercise Price (as defined below) of this Warrant was pre-paid to the Company on or prior to the initial Issuance Date and, consequently, no additional consideration shall be required to be paid by the Holder to any Person to effect any exercise of this Warrant.

1. EXERCISE OF WARRANT.

(a) Mechanics of Exercise . Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(e)), this Warrant may be exercised by the Holder on any day on or after the Initial Exercisability Date (an “ Exercise Date ”), in whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit A (the “ Exercise Notice ”), of the Holder’s election to exercise this Warrant. On or prior to the initial Issuance Date, the Holder pre-paid to the Company of an amount in cash equal to the Exercise Price then in effect multiplied by the number of Warrant Shares then issuable upon exercise of this Warrant (without regard to any limitations on exercise set forth herein) (the “ Aggregate Exercise Price ”). No additional consideration shall be required to be

paid by the Holder to any Person to effect any exercise of this Warrant. The Holder is not entitled to the return or refund of all or any portion of the pre-paid Aggregate Exercise Price under any circumstance or for any reason whatsoever, including in the event this Warrant shall not have been exercised on or prior to the Expiration Date. The Holder shall not be required to deliver an ink-original of this Warrant or an Exercise Notice in order to effect an exercise hereunder, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Exercise Notice form be required. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have the same effect as cancellation of the original of this Warrant after delivery of the Warrant Shares in accordance with the terms hereof. On or before the first (1 ^st ) Trading Day following the date on which the Company has received an Exercise Notice, the Company shall transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto as Exhibit  B , to the Holder and the Company’s transfer agent (the “ Transfer Agent ”), which confirmation shall constitute an instruction to the Transfer Agent to process such Exercise Notice in accordance with the terms herein. On or before the second (2 ^nd ) Trading Day following the date on which the Company has received such Exercise Notice (or such earlier date as required pursuant to the 1934 Act or other applicable law, rule or regulation for the settlement of a trade of such Warrant Shares initiated on the applicable Exercise Date), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“ DTC ”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, upon the request of the Holder, issue and deliver (via reputable overnight courier) to the address as specified in the Exercise Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled pursuant to such exercise. Upon delivery of an Exercise Notice, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise and upon surrender of this Warrant to the Company by the Holder, then, at the request of the Holder, the Company shall as soon as practicable and in no event later than two (2) Business Days after any exercise and at its own expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number. The Company shall pay any and all transfer, stamp, issuance

2

and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent) that may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant.

(b) Exercise Price . For purposes of this Warrant, “ Exercise Price ” means $6.61 and has been prepaid by the Holder to the Company on or prior to the initial Issuance Date.

(c) 144 Status . For purposes of Rule 144(d) promulgated under the 1933 Act, as in effect on the Subscription Date, since the Aggregate Exercise Price was paid in full on or prior to the initial Issuance Date, it is intended that the Warrant Shares issued hereunder upon exercise of this Warrant, from time to time, shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, as of the initial Issuance Date.

(d) Disputes . In the case of a dispute as to the arithmetic calculation of the number of Warrant Shares to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 13.

(e) Limitations on Exercises . The Company shall not effect the exercise of any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the terms and conditions of this Warrant and any such exercise shall be null and void and treated as if never made, to the extent that after giving effect to such exercise, the Holder together with the other Attribution Parties collectively would beneficially own in excess of 19.99% (the “ Maximum Percentage ”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by the Holder and the other Attribution Parties shall include the number of shares of Common Stock held by the Holder and all other Attribution Parties plus the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including, without limitation, any convertible notes or convertible preferred stock or warrants, including other Registered Warrants) beneficially owned by the Holder or any other Attribution Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 1(e)(i). For purposes of this Section 1(e)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of determining the number of outstanding shares of Common Stock the Holder may acquire upon the exercise of this Warrant without exceeding the Maximum Percentage, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the SEC, as the case may be, (y) a more recent public announcement by the Company or (z) any other written notice by the Company or the Transfer Agent, if any, setting forth the number of shares of Common Stock outstanding (the

3

“ Reported Outstanding Share Number ”). Within five (5) days of each month-end, the Company shall provide the Holder with the Reported Outstanding Share Number, provided that , if the fifth day of such period is not a Business Day, then the Company shall provide the Holder with the Reported Outstanding Share Number no later than the next succeeding Business Day. If the Company receives an Exercise Notice from the Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 1(e)(i), to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of Warrant Shares to be acquired pursuant to such Exercise Notice (the number of shares by which such purchase is reduced, the “ Reduction Shares ”). For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder and any other Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance of shares of Common Stock to the Holder upon exercise of this Warrant results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the 1934 Act), the number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate beneficial ownership exceeds the Maximum Percentage (the “ Excess Shares ”) shall be deemed null and void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time to time increase (with such increase not effective until the sixty-first (61 ^st ) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage not in excess of 19.99% as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61 ^st ) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties and not to any other holder of Registered Warrants that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(e)(i) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 1(e)(i) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor holder of this Warrant.

4

(f) Reservation of Shares . So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance under this Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of shares of Common Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the Registered Warrants then outstanding (without regard to any limitations on exercise) (the “ Required Reserve Amount ”); provided that at no time shall the number of shares of Common Stock reserved pursuant to this Section 1(g)(i) be reduced other than proportionally in connection with any exercise or redemption of Registered Warrants or such other event covered by Section 2(a) below. The Required Reserve Amount (including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the holders of the Registered Warrants based on number of shares of Common Stock issuable upon exercise of Registered Warrants held by each holder on the Closing Date (without regard to any limitations on exercise) or increase in the number of reserved shares, as the case may be (the “ Authorized Share Allocation ”). In the event that a holder shall sell or otherwise transfer any of such holder’s Registered Warrants, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Registered Warrants shall be allocated to the remaining holders of Registered Warrants, pro rata based on the number of shares of Common Stock issuable upon exercise of the Registered Warrants then held by such holders (without regard to any limitations on exercise).

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES . The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.

(a) Stock Dividends and Splits . Without limiting any provision of Section 3 or Section 4, if the Company, at any time on or after the Subscription Date, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then the calculation of such Exercise Price shall be adjusted appropriately to reflect such event.

5

(b) Number of Warrant Shares . Simultaneously with any adjustment to the Exercise Price pursuant to this Section 2(a), the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

(c) Calculations . All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100 ^th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issuance or sale of Common Stock.

3. RIGHTS UPON DISTRIBUTION OF ASSETS . In addition to any adjustments pursuant to Section 2 above, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “ Distribution ”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution ( provided , however , that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution (and beneficial ownership) to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation).

4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.

(a) Purchase Rights . In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “ Purchase Rights ”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could

6

have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issuance or sale of such Purchase Rights ( provided , however , that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Purchase Right (and beneficial ownership) to such extent) and such Purchase Right to such extent shall be held in abeyance for the benefit of the Holder until such time or times, if ever, as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right held similarly in abeyance) to the same extent as if there had been no such limitation).

(b) Fundamental Transactions . The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents (as defined in the Securities Purchase Agreement) in accordance with the provisions of this Section 4(b), including agreements to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to

7

receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant. Notwithstanding the foregoing, and without limiting Section 1(e) hereof, the Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental Transaction without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “ Corporate Event ”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.

(c) Application . The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the Maximum Percentage, applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of this Warrant (or any such other warrant)).

5. NONCIRCUMVENTION . The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (a) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (b) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant. Notwithstanding anything herein to the contrary, if after the seventy-five (75) calendar day anniversary of the Issuance Date, the Holder is not permitted to exercise this Warrant in full for any reason (other than pursuant to restrictions set forth in Section 1(e) hereof), the Company shall use its best

8

efforts to promptly remedy such failure, including, without limitation, obtaining such consents or approvals as necessary to permit such exercise into shares of Common Stock.

6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER . Except as otherwise specifically provided herein, the Holder, solely in its capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

7. REISSUANCE OF WARRANTS.

(a) Transfer of Warrant . If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

(b) Lost, Stolen or Mutilated Warrant . Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant (as to which a written certification and the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.

(c) Exchangeable for Multiple Warrants . This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the

9

Holder at the time of such surrender; provided, however, no warrants for fractional shares of Common Stock shall be given.

(d) Issuance of New Warrants . Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.

8. NOTICES . Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant (other than the issuance of shares of Common Stock upon exercise in accordance with the terms hereof), including in reasonable detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) promptly upon each adjustment of the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s), (ii) at least ten Trading Days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder, and (iii) the existence of a proposed Fundamental Transaction at least ten (10) Trading Days prior to the consummation of such Fundamental Transaction. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its Subsidiaries, the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement) pursuant to a Current Report on Form 8-K. It is expressly understood and agreed that the time of execution specified by the Holder in each Exercise Notice shall be definitive and may not be disputed or challenged by the Company.

9. AMENDMENT AND WAIVER . Except as otherwise provided herein, the provisions of this Warrant (other than Section 1(e)) may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

10. SEVERABILITY . If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that

10

would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

11. GOVERNING LAW . This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Company hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to the Company at the address set forth in Section 9(f) of the Securities Purchase Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. The Company hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.

If the Holder and the Company are unable to promptly resolve such dispute relating to such Closing Sale Price or such fair market value or such arithmetic calculation of the number of Warrant Shares (as the case may be), at any time after the second (2 ^nd ) Business Day following such initial notice by the Company or the Holder (as the case may be) of such dispute to the Company or the Holder (as the case may be), then the Holder may, at its sole option, select an independent, reputable investment bank to resolve such dispute.

(ii) The Holder and the Company shall each deliver to such investment bank (A) a copy of the initial dispute submission so delivered in accordance with the first sentence of this Section 13 and (B) written documentation supporting its position with respect to such dispute, in each case, no later than 5:00 p.m. (New York time) by the fifth (5 ^th ) Business Day immediately following the date on which the Holder selected such investment bank (the “ Dispute Submission Deadline ”) (the documents referred to in the immediately preceding clauses (A) and (B) are collectively referred to herein as the “ Required Dispute Documentation ”) (it being understood and agreed that if either the Holder or the Company fails to so deliver all of the Required Dispute Documentation by the Dispute Submission Deadline, then the party who fails to so submit all of the Required Dispute Documentation shall no longer be entitled to (and hereby waives its right to) deliver or submit any written documentation or other support to such investment bank with respect to such dispute and such investment bank shall resolve such dispute based solely on the Required Dispute Documentation that was delivered to such investment bank prior to the Dispute Submission Deadline). Unless otherwise agreed to in writing by both the Company and the Holder or otherwise requested by such investment bank, neither the Company nor the Holder shall be entitled to deliver or submit any written documentation or other support to such investment bank in connection with such dispute (other than the Required Dispute Documentation).

(iii) The Company and the Holder shall cause such investment bank to determine the resolution of such dispute and notify the Company and the Holder of such resolution no later than ten (10) Business Days immediately following the Dispute Submission Deadline.

The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, exercises and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate.

Holder shall not be required to physically surrender this Warrant to the Company until Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days following the date the final Exercise Form is delivered to the Company. Execution and delivery of an Exercise Form with respect to a partial Exercise shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares.

Within the earlier of (x) two (2) Trading Days and (y) the number of Trading Days comprising the Standard Settlement Period after any Date of Exercise (but, in the case of a Cash Exercise, within two (2) Business Days following the Company’s receipt of the full Exercise Price, if later) or in the case of a Cashless Default Exercise (as defined in Section 5(b) below), within the period provided in Section 3(c), as applicable (the “Delivery Period”), the Company shall issue and deliver (or cause its transfer agent (the “Transfer Agent”) to issue and deliver) in accordance with the terms hereof to or upon the order of Holder that number of shares of Common Stock (“Exercise Shares”) for the portion of this Warrant exercised as shall be determined in accordance herewith. Upon the Exercise of this Warrant or any part hereof, the Company shall, at its own cost and expense, take all necessary action, including obtaining and delivering an opinion of counsel, to assure that the Transfer Agent shall issue stock certificates in the name of Holder (or its nominee) or such other persons as designated by Holder and in such denominations as Holder shall specify at Exercise, representing the number of shares of Common Stock issuable upon such Exercise. The Company warrants that no instructions other than these instructions have been or will be given to the Transfer Agent and that, unless waived by Holder, this Warrant and the Exercise Shares will be free-trading, and freely transferable, and will not contain or be subject to a legend (or be subject to any stop transfer instruction) restricting the resale or transferability of the Exercise Shares if the Unrestricted Conditions (as defined below) are met.

The Company shall be responsible for paying all present or future stamp, court or documentary, intangible, recording, filing or similar taxes that arise from any payment or issuance made under, from the execution, delivery, performance or enforcement of, or otherwise with respect to, this Warrant.

Holder understands that until such time as this Warrant, the Exercise Shares and the Failure Payment Shares (as defined below) have been registered under the Securities Act or otherwise may be sold pursuant to Rule 144 or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, this Warrant, the Exercise Shares and the Failure Payment Shares, as applicable, may bear a restrictive legend in substantially the following form (and a stop-transfer order consistent therewith may be placed against transfer of the certificates for such securities):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, EXCEPT PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING PURSUANT TO SECTION 4(A)(7) OF THE SECURITIES ACT OR RULE 144 UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4[(a)](1) AND A HALF” SALE.” NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

(ii) Removal of Restrictive Legends . This Warrant and the certificates (or electronic book entries, if applicable) evidencing the Exercise Shares and the Failure Payment Shares, as applicable, shall not contain or be subject to any legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)) or be subject to any stop-transfer instructions: (A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering the sale or resale of such security is effective under the Securities Act, or (B) following any sale of such Warrant, Exercise Shares and/or Failure Payment Shares pursuant to Rule 144, or (C) if such Warrant, Exercise Shares and/or Failure Payment Shares are eligible for sale under Rule 144(b)(1), or (D) at any time on or after the date hereof on which Holder’s holding period for purposes of Rule 144 under the Securities Act and subsection (d)(3)(iii) thereof with respect to such Warrant, Exercise Shares and/or Failure Payment Shares is at least

6

six (6) months and Holder certifies that it is not an Affiliate of the Company, or (E) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective Date, or at such other time as any of the Unrestricted Conditions have been met, if required by the Transfer Agent to effect the issuance of this Warrant, the Exercise Shares or the Failure Payment Shares, as applicable, without a restrictive legend or removal of the legend hereunder. If any of the Unrestricted Conditions are met at the time of issuance of this Warrant, the Exercise Shares or the Failure Payment Shares, then such Warrant, Exercise Shares or Failure Payment Shares, as applicable, shall be issued free of all legends and stop-transfer instructions. The Company agrees that following the Effective Date, or at such time as the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 2(e), it will, no later than the earlier of (x) two (2) Trading Days and (y) the number of Trading Days comprising the Standard Settlement Period following the delivery (the “Unlegended Shares Delivery Deadline”) by Holder to the Company or the Transfer Agent of this Warrant and a certificate representing Exercise Shares and/or Failure Payment Shares, as applicable, issued with a restrictive legend, deliver or cause to be delivered to Holder this Warrant and/or a certificate (or electronic transfer) representing such shares that is free from all restrictive and other legends (and stop transfer instructions). For purposes hereof, “Effective Date” shall mean the date that the first Registration Statement that the Company is required to file pursuant to the Registration Rights Agreement has been declared effective by the SEC.

(iii) Sale of Unlegended Shares . Holder agrees that the removal of the restrictive legend from this Warrant and any certificates representing securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that Holder will sell this Warrant or any Exercise Shares and/or any Failure Payment Shares, as applicable, pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein.

(f) Cancellation of Warrant . This Warrant shall be canceled upon the full Exercise of this Warrant, and, as soon as practical after the Date of Exercise, Holder shall be entitled to receive Common Stock for the number of shares purchased upon such Exercise of this Warrant, and if this Warrant is not Exercised in full, Holder shall be entitled to receive a new Warrant (containing terms identical to this Warrant) representing any unexercised portion of this Warrant in addition to such Common Stock; provided, however, as set forth in Section 2(b), Holder shall not be required to physically surrender this warrant if the Warrant is not Exercised in full.

(g) Holder of Record . Each person in whose name any Warrant for shares of Common Stock is issued shall, for all purposes, be deemed to be Holder of record of such shares on the Date of Exercise, irrespective of the date of delivery of the Common Stock purchased upon the Exercise of this Warrant. Prior to the exercise of this Warrant, nothing in this Warrant shall be construed as conferring upon Holder any rights as a stockholder of the Company.

(h) Delivery of Electronic Shares . In lieu of delivering physical certificates representing the Common Stock issuable upon Exercise or legend removal, or representing Failure Payment

7

Shares, upon written request of Holder, the Company shall use its best efforts to cause the Transfer Agent to electronically transmit the Common Stock issuable upon Exercise to Holder by crediting the account of Holder’s prime broker with DTC through its Deposit/Withdrawal at Custodian (DWAC) system. The time periods for delivery and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

(i) Buy-In . In addition to any other rights or remedies available to Holder hereunder or otherwise at law or in equity, if the Company fails to cause its Transfer Agent to deliver to Holder a certificate or certificates, or electronic shares through DWAC, representing the Exercise Shares pursuant to an Exercise on or before the last day of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date Holder is required by its broker to purchase (in an open market transaction or otherwise) or Holder or Holder’s brokerage firm otherwise purchases shares of Common Stock to deliver in satisfaction of a sale by Holder of the Exercise Shares which Holder was entitled to receive upon such Exercise (a “Buy-In”), then the Company shall (1) pay in cash to Holder the amount by which (x) Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Exercise Shares that the Company was required to deliver to Holder in connection with the Exercise at issue by (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of Holder, either reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such Exercise was not honored (and refund the Exercise Price therefor, to the extent paid by Holder, and/or reinstate the principal amount of any indebtedness used to satisfy the applicable Exercise Price) or deliver to Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its Exercise and delivery obligations hereunder. For example, if Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted Exercise to cover the sale of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay Holder $1,000. Holder shall provide the Company written notice indicating the amounts payable to Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon Exercise of the Warrant as required pursuant to the terms hereof.

(j) HSR Submissions. If Holder determines that, in connection with the exercise of this Warrant, it and the Company are required to file Premerger Notification Reports with the Federal Trade Commission (the “FTC”) and the United States Department of Justice (“DOJ”) and observe the Waiting Period under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended, and the related rules and regulations promulgated thereunder (collectively, the “HSR Act”), the Company agrees to (i) cooperate with Holder in Holder’s preparing and making such submission and any responses to inquiries of the FTC and DOJ; (ii) prepare and make any submission required to be filed by the Company under the HSR Act and respond to inquiries of the FTC and DOJ in connection therewith; and (iii) reimburse Holder for the cost of the required filing fee for Holder’s submission under the HSR Act. For the avoidance of doubt, Holder shall bear all of its

8

other costs and expenses in connection with such submission, including any attorneys’ fees associated therewith.

3. Payment of Warrant Exercise Price for Cash Exercise or Cashless Exercise; Cashless Major Exercise and Cashless Default Exercise .

(a) Exercise Price . The exercise price shall initially equal $6.61 per share, subject to adjustment pursuant to the terms hereof (as so adjusted, the “Exercise Price”), including but not limited to Section 5 below.

Payment of the Exercise Price may be made by any of the following, or a combination thereof, at the election of Holder:

(i) Cash Exercise : Holder may exercise this Warrant in cash, bank or cashier’s check or wire transfer (a “Cash Exercise”);

(ii) Cashless Exercise : In lieu of paying all or any portion of the Exercise Price in cash, Holder, at its option, may exercise this Warrant (in whole or in part) on a cashless basis by making appropriate notation on the applicable Exercise Form, in which event the Company shall issue Holder a number of shares of Common Stock computed using the following formula (a “Cashless Exercise”):

X = Y (A-B)/A

where: X = the number of shares of Common Stock to be issued to Holder.

Y = the number of shares of Common Stock for which this Warrant is being Exercised.

A = the Market Price of one (1) share of Common Stock (for purposes of this Section 3(a)(ii), where “Market Price,” as of any date, means the arithmetic average of the Volume Weighted Average Price (as defined below) of the Company’s Common Stock on each of the ten (10) consecutive Trading Days immediately preceding the date in question.

B = the Exercise Price.

As used herein, the “Volume Weighted Average Price” for any security as of any date means the volume weighted average sale price on the NasdaqGS as reported by, or based upon data reported by, Bloomberg Financial Markets or an equivalent, reliable reporting service mutually acceptable to and hereafter designated by the Holder and the Company (“Bloomberg”) or, if the NasdaqGS is not the principal trading market for such security, the volume weighted average sale price of such security on the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg or, if no volume weighted average sale price is reported for such security, then the last closing trade price of such security as reported by Bloomberg, or, if no last closing trade price is reported for such security by Bloomberg, the average of the bid prices of any market makers for such security on the OTC Bulletin Board, the OTCQX Market, the OTCQB Market or the “pink” market of OTC Markets Group. If the Volume

9

Weighted Average Price cannot be calculated for such security on such date in the manner provided above, the Volume Weighted Average Price shall be the fair market value as determined by the Company and the Holder. In the event that a Stock Event is consummated during any period for which the arithmetic average of the Volume Weighted Average Price is to be determined (under this Section or otherwise), the Volume Weighted Average Price for all Trading Days during such period prior to the effectiveness of the Stock Event shall be appropriately adjusted to reflect such Stock Event.

(iii) Note Exchange Exercise : In lieu of paying all or any portion of the Exercise Price in cash, Holder, at its option, may exercise this Warrant (in whole or in part) through a reduction of an amount of principal outstanding under any First Out Waterfall Notes in accordance with Section 2.3(b) of the Facility Agreement, then held by Holder (a “Note Exchange Exercise”)

For purposes of Rule 144 and subsection (d)(3)(ii) thereof, it is intended, understood and acknowledged that the shares of Common Stock issuable upon Exercise of this Warrant in a Cashless Exercise (including a Cashless Major Exercise or Cashless Default Exercise) transaction or a Note Exchange Exercise transaction shall be deemed to have been acquired on April 3, 2017. Accordingly, (A) upon any such Exercise, the Rule 144 holding period for the shares of Common Stock issued thereupon shall be in excess of one (1) year, and (B) provided that Holder is not an “affiliate” (as defined in Rule 144 under the Securities Act) of the Company on the date of such Exercise (which the Company shall assume unless advised otherwise in writing by Holder), an Unrestricted Condition shall be satisfied with respect to the shares of Common Stock issued thereupon and such shares will be freely transferable, without restriction or limitation (including any volume limitation or current public information requirement) under Federal or state securities laws, pursuant to Rule 144 under the Securities Act, and will not contain or be subject to a legend or stop transfer order restricting the resale or transferability of thereof.

As provided in Section 2(b), Holder shall only be required to physically surrender this Warrant in the event that Holder is exercising this Warrant in full.

(b) Cashless Major Exercise. To the extent Holder shall exercise this Warrant as a Cashless Major Exercise pursuant to Section 5(b)(i) and 5(b)(iii) below, Holder shall send to the Company (in any manner permitted under Section 2(a)) the Exercise Form indicating that Holder is exercising this Warrant (or any portion thereof) pursuant to a Cashless Major Exercise, in which event the Company shall issue a number of shares of Common Stock equal to the Black-Scholes Value of the Warrant (or such applicable portion being exercised) divided by the closing price of the Common Stock on the principal securities exchange or other securities market on which the Common Stock is then traded on the Trading Day immediately preceding the date on which the applicable Major Transaction is consummated, or, if in respect of a Cashless Major Exercise made after the date of consummation of the applicable Major Transaction, on the Trading Day immediately preceding the date on which the exercise form in respect of such Cashless Major Exercise is delivered. As provided in Section 2(b), Holder shall only be required to physically surrender this Warrant in the event that Holder is exercising this Warrant in full. Holder shall be permitted to make successive Cashless Major Exercises and send successive Exercise Forms in

10

respect of a Cashless Major Exercise from time to time at any time during the Cashless Major Exercise Period.

(c) Cashless Default Exercise . To the extent Holder exercises this Warrant as a Cashless Default Exercise pursuant to Section 11(b)(i) below, Holder shall send to the Company (in any manner permitted under Section 2(a)) the Exercise Form indicating that Holder is exercising this Warrant pursuant to a Cashless Default Exercise, in which event the Company shall issue to Holder, within five (5) Trading Days of the applicable Default Notice, a number of shares of Common Stock (which shares shall be valued at the closing price of the Common Stock on the principal securities exchange or other securities market on which the Common Stock is then traded on the Trading Day immediately preceding the date on which the Exercise Form in respect of such Cashless Default Exercise is delivered) equal to the Black-Scholes Value of the remaining unexercised portion of this Warrant (or such portion thereof subject to such exercise) as of the date of such Default Notice (or in the case of an Event of Default referred to in Section 11(a)(vi), on the Trading Day immediately preceding the date the dividend or distribution is declared or, if not first declared, is paid). As provided in Section 2(b), the Holder shall be permitted to make successive Cashless Default Exercises and send successive Exercise Forms in respect of a Cashless Default Exercise, from time to time at any time from and after the date of the applicable Default Notice through the Term of this Warrant.

(d) Dispute Resolution . In the case of a dispute as to the determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock or the arithmetic calculation of the Exercise Price, Market Price or the Successor Major Transaction Consideration, or the number of shares issuable upon a Cashless Major Exercise, the Company shall submit the disputed determinations or arithmetic calculations via electronic mail within two (2) Business Days of receipt, or deemed receipt, of the Exercise Form or Major Transaction Early Termination Notice, or other event giving rise to such dispute, as the case may be, to Holder. If Holder and the Company are unable to agree upon such determination or calculation within two (2) Business Days of such disputed determination or arithmetic calculation being submitted to Holder, then the Company shall, within two (2) Business Days submit via electronic mail (i) the disputed determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock to an independent, reputable investment bank selected by the Company and approved by Holder, which approval shall not be unreasonably withheld, or (ii) the disputed arithmetic calculation of the Exercise Price, Market Price, any Successor Major Transaction Consideration or number of shares issuable upon a Cashless Major Exercise to the Company’s independent, outside registered public accountants. The Company shall use its reasonable best efforts to cause the investment bank or the accountants, as the case may be, to perform the determinations or calculations and notify the Company and Holder of the results no later than five (5) Trading Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountants’ determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error, and the Company and Holder shall each pay one half of the fees and costs of such investment banker or accountant. Notwithstanding the existence of a dispute contemplated by this paragraph, if requested by Holder, the Company shall issue to Holder the Exercise Shares not in dispute in accordance with the terms hereof.

11

4. Transfer and Registration .

(a) Transfer Rights . Subject to the provisions of Section 8 of this Warrant, this Warrant may be transferred on the books of the Company, in whole or in part, in person or by attorney, upon surrender of this Warrant properly completed and endorsed. This Warrant shall be canceled upon such surrender and, as soon as practicable thereafter, the person to whom such transfer is made shall be entitled to receive a new Warrant or Warrants as to the portion of this Warrant transferred, and Holder shall be entitled to receive a new Warrant as to the portion hereof retained.

(b) Registrable Securities . The Common Stock issuable upon the Exercise of this Warrant entitles Holder (and applicable assignees or transferees of such Common Stock) to registration and other rights pursuant to the Registration Rights Agreement.

5. Adjustments Upon Certain Events .

(a) Recapitalization or Reclassification . If the Company shall at any time effect a stock split, payment of stock dividend, recapitalization, reclassification or other similar transaction of such character that the shares of Common Stock shall be changed into or become exchangeable for a larger or smaller number of shares, then upon the effective date thereof, the number of shares of Common Stock which Holder shall be entitled to purchase upon Exercise of this Warrant, shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of shares of Common Stock by reason of such stock split, payment of stock dividend, recapitalization, reclassification or similar transaction, and the Exercise Price shall be, in the case of an increase in the number of shares, proportionally decreased and, in the case of decrease in the number of shares, proportionally increased. The Company shall give Holder the same notice it provides to holders of Common Stock of any transaction described in this Section 5(a).

(b) Rights Upon Major Transaction .

(i) Major Transaction . In the event that a Major Transaction occurs, then (1) in the case of a Successor Major Transaction, Holder, at its option, may elect to cause the conversion of this Warrant (a “Successor Major Transaction Conversion”), in whole or in part, into the right to receive the Successor Major Transaction Consideration, upon consummation of the Major Transaction, and (2) in the case of all other Major Transactions, Holder shall have the right to exercise this Warrant (or any portion thereof), at any time and from time to time following the occurrence of such event, as a Cashless Major Exercise. In the event Holder shall not have exercised any of its rights under clauses (1) or (2) above within the applicable time periods set forth herein, then the Major Transaction shall be treated as an Assumption (as defined below) in accordance with Section 5(b)(ii) below unless Holder waives its rights under this Section 5(b) with respect to such Major Transaction. Each of the following events shall constitute a “Major Transaction”:

(A) a consolidation, merger, exchange of shares, recapitalization, reorganization, business combination or other similar event, (1) following which the holders of Common Stock immediately preceding such consolidation, merger, exchange, recapitalization,

12

reorganization, combination or event either (a) no longer hold a majority of the shares of Common Stock or (b) no longer have the ability to elect a majority of the board of directors of the Company or (2) as a result of which shares of Common Stock shall be changed into (or the shares of Common Stock become entitled to receive) the same or a different number of shares of the same or another class or classes of stock or securities of the Company or another entity (collectively, a “Change of Control Transaction”);

(B) the sale or transfer, in one transaction or a series of related transactions, of (I) all or substantially all of the assets of the Company (including, for the avoidance of doubt, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole) to any Person other than a wholly-owned subsidiary of the Company or (II) assets of the Company (including, for the avoidance of doubt, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole) for a purchase price equal to more than 50% of the Equity Value (as defined below) of the Company. For purposes of this clause (B), “Equity Value” shall mean (I) the product of (x) the number of issued and outstanding shares of Common Stock on the date the Company delivers the Major Transaction Notice (defined below) multiplied by (y) the per share closing price of the Common Stock on such date on the NasdaqGS as reported by, or based upon data reported by, Bloomberg or, if the NasdaqGS is not the principal trading market for such security, the closing sale price of such security on the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg;

(C) a purchase, tender or exchange offer made to the holders of outstanding shares of Common Stock, such that following such purchase, tender or exchange offer a Change of Control Transaction shall have occurred;

(D) the liquidation, bankruptcy, insolvency, dissolution or winding-up (or the occurrence of any analogous proceeding) affecting the Company;

(E) the shares of Common Stock cease to be listed, traded or publicly quoted on the NasdaqGS and are not promptly re-listed or requoted on the New York Stock Exchange, the NYSE American, the NASDAQ Global Market or the NASDAQ Capital Market; or

(F) the Common Stock ceases to be registered under Section 12 of the Exchange Act.

(ii) Assumption. Any assumption of Company obligations under this paragraph shall be referred to herein as an “Assumption.” Unless otherwise provided in writing by Holder, the Company shall not consummate a Major Transaction in which the Company is not the surviving entity or

13

as a result of which the Company has a new Parent Entity, unless (A) each Person acquiring the Company’s assets or Common Stock (or Parent Entity thereof, as applicable), or any other successor entity resulting from such Major Transaction (in each case, a “Successor Entity”), assumes in writing all of the obligations of the Company under this Warrant, the Facility Agreement (but, other than with respect to the Company’s obligations pursuant to Section 5.1(e) and 5.1(p) of the Facility Agreement and the other provisions of the Facility Agreement that expressly survive the repayment of the Loans (which shall be assumed in any Assumption), only if there are outstanding Loans under the Facility Agreement immediately following the consummation of the Major Transaction) and the Registration Rights Agreement in accordance with the provisions of this Section 5(b)(ii) pursuant to written agreements in form and substance reasonably satisfactory to Holder and approved by Holder prior to the consummation of such Major Transaction (such approval not to be unreasonably withheld or delayed), including agreements to deliver to Holder in exchange for its Warrants a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Warrants, that, among other things, (1) is exercisable for the appropriate number of shares of the Successor Entity’s capital stock (without regard to the 4.985% Cap or any other restriction or limitation on exercise, provided that such instrument shall contain a limitation on exercise comparable to that contained in the second paragraph of Section 1 of this Warrant); (2) has an exercise price similar to the then-effective Exercise Price (taking into account any conversion or exchange ratio applicable to the Common Stock in the Major Transaction) and exercise price adjustment provisions similar to those in the Warrants; (3) entitles Holder to such additional securities or other consideration as Holder would be entitled pursuant to Section 5(b)(i) in connection with the Major Transaction; and (4) provides for registration rights similar to those provided by the Registration Rights Agreement, in each case reasonably satisfactory to Holder, and (B) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. For the avoidance of doubt, Holder’s reasonable satisfaction referred to in the immediately preceding sentence shall be construed only to apply to confirmation that the warrant or other comparable security and registration rights agreement delivered to Holder upon an assumption hereunder shall conform to the requirements of this Section 5(b)(ii), and this Section 5(b)(ii) shall not be construed as granting consent or approval rights to Holder with respect to the terms of such Major Transaction or to permit Holder to demand any additional consideration in respect of this Warrant other than as provided herein. Upon the occurrence of any Major Transaction, any Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Major Transaction, the provisions of this Warrant and the Registration Rights Agreement referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Major Transaction, the Successor Entity shall deliver to Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the Major Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the Warrants prior to such Major Transaction, such shares of publicly traded common stock (or their equivalent) of the Successor Entity, as adjusted in accordance with the provisions of this Warrant. The provisions of this Section shall apply similarly and equally to successive Major Transactions and shall be

14

applied without regard to any limitations on the exercise of this Warrant other than any applicable beneficial ownership limitations.

(iii) Major Transaction Notice; Major Transaction Early Termination Right; Notice of Cashless Major Exercise. At least thirty (30) days prior to the consummation of any Major Transaction, but, in any event, within five (5) Trading Days following the first to occur of (x) the date of the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, or (y) the day following the public announcement of such Major Transaction if such announcement is made on and after 4:00 p.m., New York City time, the Company shall deliver written notice thereof via electronic mail and overnight courier to Holder (a “Major Transaction Notice”). At any time during the period beginning after Holder’s receipt of a Major Transaction Notice in respect of a Successor Major Transaction and ending five (5) Trading Days prior to the consummation of such Major Transaction (the “Early Termination Period”), Holder may elect a Successor Major Transaction Conversion by delivering written notice thereof (“Major Transaction Early Termination Notice”) to the Company, which Major Transaction Early Termination Notice shall indicate the portion of the Warrant (with reference to the number of shares of Common Stock issuable upon a Cash Exercise of such portion, without regard to the 4.985% Cap) that Holder is electing to be treated as a Successor Major Transaction Conversion. The portion of this Warrant subject to early termination pursuant to this Section 5(b)(iii), shall be converted into the right to receive the Successor Major Transaction Consideration

To the extent Holder shall elect to effect a Cashless Major Exercise in respect of a Major Transaction, Holder shall deliver its Exercise Form in accordance with Section 3(b), at any time and from time to time following receipt by Holder of the Major Transaction Notice until the later of (x) the last day of the Term and (y) the one-year anniversary of the applicable Major Transaction (the “Cashless Major Exercise Period”). For the avoidance of doubt, Holder shall be permitted to make successive Cashless Major Exercises and send successive Exercise Forms in respect of a Cashless Major Exercise from time to time at any time during the Cashless Major Exercise Period.

(iv) Escrow; Payment of Successor Major Transaction Consideration . Following the receipt of a Major Transaction Early Termination Notice in respect of a Successor Major Transaction from Holder, the Company shall not effect a Successor Major Transaction with respect to which Holder has elected a Successor Major Transaction Conversion unless either (A) it obtains, as a condition precedent to such Major Transaction, the written agreement of the Successor Entity that payment of the Successor Major Transaction Consideration shall be made to Holder concurrently with consummation of such Successor Major Transaction, or (B) it shall place the Successor Major Transaction Consideration into an escrow account with an independent escrow agent, and shall instruct the escrow agent to deliver the Successor Major Transaction Consideration to Holder, concurrently with the consummation of the Major Transaction. Notwithstanding clauses (A) and (B) above, Holder shall be treated on a pari passu basis with, and shall not have priority to payments to, the holders of Common Stock in connection with a Major Transaction. For purposes of determining the amount required to be placed in escrow pursuant to the provisions of this subsection (iv) and without affecting the amount of the actual Successor Major Transaction Consideration, the calculation of the price referred to in clause (1) of the first column of Schedule 1 hereto with respect to Stock Price shall be determined based on

15

the Closing Market Price (as defined on Schedule 1) of the Common Stock on the Trading Day immediately preceding the date that the Successor Major Transaction Consideration is deposited with the escrow agent.

(v) Injunction . Following the receipt of a Major Transaction Early Termination Notice from Holder, in the event that the Company attempts to consummate a Successor Major Transaction without either (1) placing the Successor Major Transaction Consideration in escrow in accordance with subsection (iv) above, or (2) obtaining the written agreement of the Successor Entity as described in subsection (iv) above, Holder shall have the right to apply for an injunction in any state or federal court sitting in the City of New York, borough of Manhattan to prevent the closing of such Major Transaction until the Successor Major Transaction Consideration is delivered to Holder.

An early termination required by this Section 5(b) shall be made in accordance with the provisions of Section 12. To the extent an early termination required by this Section 5(b) is deemed or determined by a court of competent jurisdiction to be prepayments of the Warrant by the Company, such early termination shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, until the Successor Major Transaction Consideration is paid in full, this Warrant may be exercised, in whole or in part, by Holder into shares of Common Stock, or in the event the date of any Exercise is after the consummation of the Major Transaction, shares of publicly traded common stock (or their equivalent) of the Successor Entity pursuant to Section 5(b). The parties hereto agree that in the event of the Company’s early termination of any portion of the Warrant under this Section 5(b), Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for Holder. Accordingly, any premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a commercially reasonable estimate of Holder’s actual loss of its investment opportunity and not as a penalty.

(c) Exercise Price Adjusted . As used in this Warrant, the term “Exercise Price” shall mean the purchase price per share specified in Section 3(a) of this Warrant, until the occurrence of an event stated in this Section 5 or otherwise set forth in this Warrant, and thereafter shall mean said price as adjusted from time to time in accordance with the provisions of said subsection. No adjustment made pursuant to any provision of this Section 5 shall have the net effect of increasing the aggregate Exercise Price payable hereunder or, except as expressly provided in Section 5(a), otherwise increasing the Exercise Price.

(d) Adjustments: Additional Shares, Securities or Assets . In the event that at any time, as a result of an adjustment made pursuant to this Section 5 or otherwise, Holder shall, upon Exercise of this Warrant, become entitled to receive shares and/or other securities or assets (other than Common Stock) then, wherever appropriate, all references herein to shares of Common Stock shall be deemed to refer to and include such shares and/or other securities or assets; and thereafter the number of such shares and/or other securities or assets shall be subject to adjustment from time to time in a manner and upon terms as nearly equivalent as practicable to the provisions of this Section 5.

16

(e) Notice of Adjustments . Whenever the Exercise Price and/or number or type of securities issuable upon Exercise is adjusted pursuant to the terms of this Warrant, the Company shall promptly mail to Holder a notice (an “Exercise Price Adjustment Notice”) setting forth the Exercise Price and/or number or type of securities issuable upon Exercise after such adjustment and setting forth a statement of the facts requiring such adjustment. The Company shall, upon the written request at any time of Holder, furnish to Holder a like Warrant setting forth (i) such adjustment or readjustment, (ii) the Exercise Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon Exercise of the Warrant. For purposes of clarification, whether or not the Company provides an Exercise Price Adjustment Notice pursuant to this Section 5(e), upon the occurrence of any event that leads to an adjustment of the Exercise Price, Holder would be entitled to receive a number of Exercise Shares based upon the new Exercise Price, as adjusted, for exercises occurring on or after the date of such adjustment, regardless of whether Holder accurately refers to the adjusted Exercise Price in the Exercise Form.

6. Fractional Interests .

No fractional shares or scrip representing fractional shares shall be issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, Holder may purchase only a whole number of shares of Common Stock. If, on Exercise of this Warrant, Holder would be entitled to a fractional share of Common Stock or a right to acquire a fractional share of Common Stock, such fractional share shall be disregarded and the number of shares of Common Stock issuable upon Exercise shall be the next higher whole number of shares.

7. Reservation of Shares .

From and after the date hereof, the Company shall at all times reserve for issuance such number of authorized and unissued shares of Common Stock (or other securities substituted therefor as herein above provided) as shall be sufficient for the Exercise of this Warrant and payment of the Exercise Price. If at any time the number of shares of Common Stock authorized and reserved for issuance is below the number of shares sufficient for the Exercise of this Warrant (a “Share Authorization Failure”) (based on the Exercise Price in effect from time to time), the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations under this Section 7, in the case of an insufficient number of authorized shares, and using its best efforts to obtain stockholder approval of an increase in such authorized number of shares. The Company covenants and agrees that upon the Exercise of this Warrant, all shares of Common Stock issuable upon such Exercise shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive rights, rights of first refusal or similar rights of any Person. The Company covenants and agrees that all shares of Common Stock issuable upon Exercise of this Warrant shall be approved for listing on the NasdaqGS, or, if the NasdaqGS is not the principal trading market for the Common Stock, such principal market on which the Common Stock is traded or listed.

17

8. Restrictions on Transfer .

(a) Registration or Exemption Required . This Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Section 4(a)(2) of the Securities Act and Rule 506 thereunder and exempt from registration or qualification under applicable state securities (or “blue sky”) laws. None of the Warrant, the Exercise Shares or Failure Payment Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws, including Rule 144 under the Securities Act, Section 4(a)(7) of the Securities Act or a so-called “4[(a)](1) and a half” transaction.

(b) Assignment . Subject to Section 8(a), Holder may sell, transfer, assign, pledge, or otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a written notice to the Company, substantially in the form of the Assignment attached hereto as Exhibit  B , indicating the Person or Persons to whom the Warrant shall be assigned and the respective number of warrants to be assigned to each assignee. The Company shall effect the assignment within three (3) Business Days of its receipt of a completed and executed form of Assignment (the “Transfer Delivery Period”), and shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of like tenor and terms entitling Holder to purchase the appropriate number of shares. This Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns of Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or transfer is a so called “4[(a)](1) and half” transaction, the parties hereto agree that a legal opinion from outside counsel for Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit  C shall be the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4[(a)](1) and half” transaction.

9. Noncircumvention .

The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.

10. Events of Failure; Definition of Black Scholes Value .

(a) Definition.

The occurrence of each of the following shall be considered to be an “Event of Failure.”

18

(i) A Delivery Failure occurs, where a “Delivery Failure” shall be deemed to have occurred if the Company fails to use its best efforts to deliver Exercise Shares to Holder within any applicable Delivery Period (other than due to the limitation contained in the second paragraph of Section 1);

(ii) A Legend Removal Failure occurs, where a “Legend Removal Failure” shall be deemed to have occurred if the Company fails to use its best efforts to issue this Warrant and/or Exercise Shares without a restrictive legend, or fails to use it best efforts to remove a restrictive legend, when and as required under Section 2(e) hereof;

(iii) a Transfer Delivery Failure occurs, where a “Transfer Delivery Failure” shall be deemed to have occurred if the Company fails to use its best efforts to deliver a Warrant within any applicable Transfer Delivery Period; and

(iv) a Registration Failure (as defined below).

For purpose hereof, “Registration Failure” means that (A) the Company fails to file with the SEC on or before the Filing Deadline (as defined in the Registration Rights Agreement) any Registration Statement required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, (B) the Company fails to use its reasonable best efforts to obtain effectiveness with the SEC, prior to the Registration Deadline (as defined in the Registration Rights Agreement), and if such Registration Statement does not become effective prior to the Registration Deadline, as soon as possible thereafter, of any Registration Statement (as defined in the Registration Rights Agreement) that is required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, or fails to use its reasonable best efforts to keep such Registration Statement current and effective as required in Section 3 of the Registration Rights Agreement, (C) the Company fails to file any additional Registration Statement required to be filed pursuant to Section 2(a)(ii) of the Registration Rights Agreement on or before the Additional Filing Deadline (as defined in the Registration Rights Agreement) or fails to use its reasonable best efforts to cause such new Registration Statement to become effective on or before the Additional Registration Deadline (as defined in the Registration Rights Agreement), and if such effectiveness does not occur within such period, as soon as possible thereafter, (D) the Company fails to file any amendment to any Registration Statement, or any additional Registration Statement required to be filed pursuant to Section 3(b) of the Registration Rights Agreement within thirty (30) days of the applicable Registration Trigger Date (as defined in the Registration Rights Agreement), or fails to use its reasonable best efforts to cause such amendment and/or new Registration Statement to become effective within ninety (90) days of the applicable Registration Trigger Date, and, if such effectiveness does not occur within such period, as soon as possible thereafter, (E) any Registration Statement required to be filed under the Registration Rights Agreement, after its initial effectiveness and during the applicable Registration Period (as defined in the Registration Rights Agreement), lapses in effect or, other than on a day during an Allowable Grace Period (as defined in the Registration Rights Agreement), sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) cannot otherwise be made thereunder (whether by reason of the Company’s failure to amend or supplement the prospectus included therein in accordance with the Registration Rights Agreement, the Company’s failure to file and use its reasonable best efforts to obtain effectiveness with the SEC of an additional Registration Statement or amended Registration Statement required pursuant to Section 2(a)(ii) or 3(b) of the Registration Rights Agreement, as applicable, or otherwise), or (F) the Company fails to provide

19

a commercially reasonable written response to any comments to any Registration Statement submitted by the SEC within twenty-five (25) days of the date that such SEC comments are received by the Company.

(b) Failure Payments; Black-Scholes Determination. The Company understands that any Event of Failure (as defined above) could result in economic loss to Holder. In the event that any Event of Failure occurs, as compensation to Holder for such economic loss, the Company agrees to pay to Holder an amount payable, at the Company’s option, either (i) in cash or (ii) in shares of Common Stock that are valued for these purposes at the Volume Weighted Average Price on the date of such calculation (“Failure Payments” and such shares, “Failure Payment Shares”), in each case equal to the total economic loss of Holder determined on a commercially reasonable basis in connection with such Event of Failure for the relevant period (as recalculated on the first Business Day of each month thereafter for as long as Failure Payments shall continue to accrue) from the date of such Event of Failure until the Event of Failure is cured; provided, however, that in the event the Company elects to make Failure Payments in Failure Payment Shares, the Company shall issue, and Holder shall only receive, up to such number of shares of Common Stock in respect of Failure Payments such that Holder and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein) shall not collectively beneficially own greater than 4.985% of the total number of shares of Common Stock of the Company then issued and outstanding, and the balance of such Failure Payments shall be paid in cash. For purposes of clarification, it is agreed and understood that Failure Payments shall continue to accrue following any Event of Default until the applicable Default Amount is paid in full. The Company shall satisfy any Failure Payments under this Section pursuant to Section 10(c) below. Failure Payments are in addition to any Shares that Holder is entitled to receive upon Exercise of this Warrant.

(c) Payment of Accrued Failure Payments. The Failure Payments and Failure Payment Shares representing accrued Failure Payments for each Event of Failure shall be paid or issued and delivered, as the case may be, on or before the fifth (5th) Business Day of each month following a month in which Failure Payments accrued. Nothing herein shall limit Holder’s right to pursue actual damages (to the extent in excess of the Failure Payments) for the Company’s Event of Failure, and Holder shall have the right to pursue all remedies available at law or in equity (including a decree of specific performance and/or injunctive relief). Notwithstanding the above, if a particular Event of Failure results in an Event of Default pursuant to Section 11 hereof, then the Failure Payment, for that Event of Failure only, shall be considered to have been satisfied upon payment to Holder of an amount equal to the greater of (i) the Failure Payment, or (ii) the Default Amount, payable in accordance with Section 11.

(d) Maximum Interest Rate. Nothing contained herein or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest or dividends required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Company to Holder and thereby refunded to the Company.

20

11. Default .

(a) Events Of Default . Each of the following events shall be considered to be an “Event of Default,” unless waived by Holder:

(i) Failure To Effect Registration. With respect to all Registration Failures, a Registration Failure occurs and remains uncured for a period of more than forty-five (45) days (or sixty (60) days in the case where the Company (i) has, by the Filing Deadline (as defined the Registration Rights Agreement) filed a Registration Statement (as defined in the Registration Rights Agreement) covering this Warrant and the number of shares required by the Registration Rights Agreement, and (ii) has responded in writing to any comments to the Registration Statement that the Company has received from the SEC, within ten (10) Business Days of such receipt, and nevertheless the SEC has not declared effective a Registration Statement covering the this Warrant and the Shares by the Registration Deadline (as defined in the Registration Rights Agreement)), and such Registration Failure relates solely to the Company’s failure to have the Registration Statement declared effective by the Registration Deadline (as defined in the Registration Rights Agreement) and with respect to a Registration Failure provided in clause (E) of the definition of “Registration Failure,” such Registration Failure occurs and remains uncured for a period of more than forty-five (45) days.

(ii) Failure To Deliver Common Stock . A Delivery Failure (as defined above) occurs and remains uncured for a period of more than twenty (20) days; or at any time, the Company announces or states in writing that it will not honor its obligations to issue shares of Common Stock to Holder upon Exercise by Holder of the Exercise rights of Holder in accordance with the terms of this Warrant.

(iii) Legend Removal Failure . A Legend Removal Failure (as defined above) occurs and remains uncured for a period of twenty (20) days;

(iv) Transfer Delivery Failure . A Transfer Delivery Failure (as defined above) occurs and remains uncured for a period of twenty (20) days;

(v) Corporate Existence; Major Transaction . (A) The Company has failed to (1) place the Successor Major Transaction Consideration into escrow and instruct the escrow agent to release the Successor Major Transaction Consideration to the Holder pursuant to Section 5(b)(iii), or (2) obtain the written agreement of the Successor Entity and cause the Successor Entity to make payment as described in Section 5(b)(iii), (B) the Successor Major Transaction Consideration is not paid contemporaneously with the consummation of the Successor Major Transaction, or (C) with respect to a Major Transaction that is to be treated as an Assumption under the terms hereof, the Company has failed to meet the Assumption requirements of Section 5(b)(i); or

(vi) Section  13 Breach . During the Dividend Restriction Period, the Company declares or pays any dividend or distribution of any kind to the holders of Common Stock of the Company.

21

(b) Mandatory Early Termination .

(i) Mandatory Early Termination Amount; Cashless Default Exercise . The Company shall notify Holder in writing within two (2) Business Days of the occurrence of an Event of Default. If any Events of Default shall occur then, at the option of Holder, such option exercisable through the delivery of written notice to the Company by such Holder (the “Default Notice”), the Company shall have the right to terminate the outstanding amount of this Warrant and pay to Holder (a “Mandatory Early Termination”), in full satisfaction of its obligations hereunder by delivery of a notice to such effect to Holder within two (2) Business Days following receipt of the Default Notice, an amount payable in cash (the “Mandatory Early Termination Amount” or the “Default Amount”) equal to the Black-Scholes Value of the remaining unexercised portion of this Warrant on the date of such Default Notice (or in the case of an Event of Default referred to in Section 11(a)(vi), on the Trading Day immediately preceding the date the dividend or distribution is declared or, if not first declared, is paid). In the event the Company does not exercise its right to consummate a Mandatory Early Termination, then Holder shall have the right to exercise this Warrant, at any time and from time to time, pursuant to a Cashless Default Exercise in accordance with Section 3(c) above.

The Mandatory Early Termination Amount shall be payable within five (5) Business Days following the date of the applicable Default Notice.

(ii) Liquidated Damages . The parties hereto acknowledge and agree that the sums payable as Failure Payments or pursuant to a Mandatory Early Termination shall constitute partial liquidated damages and not penalties. The parties further acknowledge that (i) the amount of loss or damages likely to be incurred by Holder is incapable or is difficult to precisely estimate, (ii) the amounts specified bear a reasonable proportion and are not plainly or grossly disproportionate to the probable loss likely to be incurred by Holder, and (iii) the parties are sophisticated business parties and have been represented by sophisticated and able legal and financial counsel and negotiated this agreement at arm’s length.

Upon the occurrence of an Event of Default, the Default Amount, together with all other amounts payable hereunder, shall immediately become due and payable, all without demand, presentment or notice, all of which hereby are expressly waived, together with all costs, including legal fees and expenses, of collection, and Holder shall be entitled to exercise all other rights and remedies available at law or in equity.

(c) Posting Of Bond . In the event that any Event of Default occurs hereunder, the Company may not raise as a legal defense (in any Lawsuit, as defined below, or otherwise) or justification to such Event of Default any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation of law, unless the Company has posted a surety bond (a “Surety Bond”) for the benefit of such Holder in the amount of 130% of the aggregate Surety Bond Value (as defined below) of all of Holder’s Warrants (the “Bond Amount”), which Surety Bond shall remain in effect until the completion of litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.

For purposes hereof, a “Lawsuit” shall mean any lawsuit, arbitration or other dispute resolution filed by either party herein pertaining to any of this Warrant, the Facility Agreement, the

22

Registration Rights Agreement or any other Loan Document (as defined in the Facility Agreement).

“Surety Bond Value,” for the Warrants shall mean 130% of the of the Black-Scholes Value of the remaining unexercised portion of this Warrant on the Trading Day immediately preceding the date that such bond goes into effect.

(d) Injunction And Posting Of Bond . In the event that the Event of Default referred to in subsection (a) of this Section 11 pertains to the Company’s failure to deliver unlegended shares of Common Stock to Holder pursuant to a Warrant Exercise, legend removal request, or otherwise, the Company may not refuse such unlegended share delivery based on any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation of law, unless an injunction from a court, on prior notice to Holder, restraining and or enjoining Exercise of all or part of said Warrant shall have been sought and obtained by the Company and the Company has posted a Surety Bond for the benefit of such Holder in the amount of the Bond Amount, which Surety Bond shall remain in effect until the completion of litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.

(e) Remedies, Other Obligations, Breaches And Injunctive Relief . The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, the Facility Agreement, the Registration Rights Agreement and any other Loan Document, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach (including a breach or threatened breach of Section 13), the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

12. Holder’s Early Terminations .

(a) Mechanics of Holder’s Early Terminations . In the event that the Company does not deliver the applicable Successor Major Transaction Consideration or Default Amount or the Exercise Shares in respect of an election of a Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default or Exercise, as the case may be, to Holder within the time period or as otherwise required pursuant to the terms hereof, at any time thereafter Holder shall have the option, upon notice to the Company, in lieu of an election of a Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default Exercise or Exercise, as the case may be, to require the Company to promptly return to Holder all or any portion of this Warrant that was submitted for election of a Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default Exercise or Exercise, as the case may be. Upon the Company’s receipt of such notice, (x) the applicable election of Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default Exercise or Exercise, as the case may be, shall be null and void with respect to such applicable portion of this Warrant, (y) the Company shall immediately return this

23

Warrant, or issue a new Warrant to Holder representing the portion of this Warrant that was submitted for election of Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default Exercise or Exercise, as the case may be, and (z) the Exercise Price of this Warrant or such new Warrant shall be adjusted to the Exercise Price as in effect on the date on which the applicable election of Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default Exercise or Exercise, as the case may be, is voided. Holder’s delivery of a notice voiding an election of a Successor Major Transaction Conversion, Cashless Major Exercise, Cashless Default Exercise or Exercise, as the case may be, and exercise of its rights following such notice shall not affect the Company’s obligations to make any Failure Payments which have accrued prior to the date of such notice with respect to the Warrant subject to such notice.

13. Dividend Restrictions .

Until the earlier of the expiration of the Term and the date all of the Warrants are exercised in full (the “Dividend Restriction Period”), the Company shall not declare or pay any dividend or distribution of any kind to the holders of Common Stock of the Company.

14. Benefits of this Warrant .

Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. The parties hereby waive all rights to a trial by jury. If either party shall commence an action or proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or proceeding shall be

24

Notwithstanding anything herein to the contrary, the Company shall not issue to Holder, and Holder may not acquire, a number of shares of Common Stock upon exercise of this Warrant to the extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by Holder and its Affiliates and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with Holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (including shares held by any “group” of which Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein), would exceed 4.985% of the total number of shares of Common Stock then issued and outstanding (the “4.985% Cap”); provided, however, that the 4.985% Cap shall only apply to the extent that the Common Stock is deemed to constitute an “equity security” pursuant to Rule 13d-1(i) promulgated under the Exchange Act. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the Securities and Exchange Commission (the “SEC”), and the percentage held by Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act.

With respect to a Holder, any investment fund or managed account that is managed on a discretionary basis by the same investment manager as such Holder shall, for purposes hereof, be deemed to be an Affiliate of such Holder.

2. Exercise .

(a) Manner of Exercise . During the Exercise Period (or, in respect of a Cashless Major Exercise, the Cashless Major Exercise Period (as defined below)), this Warrant may be Exercised as to all or any lesser number of whole shares of Common Stock covered hereby (the “Warrant Shares” or the “Shares”) by sending to the Company the Exercise Form attached hereto as Exhibit  A-1 (the “Exercise Form”) duly completed and executed, and, if applicable, the full Exercise Price (as defined below, which may be satisfied by a Cash Exercise, a Cashless Exercise or a Note Exchange Exercise, as each is defined below) for each share of Common Stock as to which this Warrant is Exercised, at the office of the Company, 2 Musick, Irvine, CA 92618, Attention: Chief Financial Officer; Phone: (949) 595-7200, Email: vmahboob@endologix.com, or at such other office or agency as the Company may designate in writing, by overnight mail or electronic mail (any such exercise of the Warrant being hereinafter called an “Exercise” of this Warrant).

(b) Date of Exercise . The “Date of Exercise” of the Warrant shall, in each case, be the date that the Exercise Form attached hereto as Exhibit  A-1 , completed and executed, is sent by electronic mail to the Company, provided that the Exercise Price is satisfied as soon as practicable thereafter but in no event later than two (2) Business Days following the date of such electronic mail. Alternatively, the Date of Exercise shall be defined as the date the original Exercise Form is received by the Company, if Holder has not previously sent the Exercise Form by electronic mail. Upon delivery of the Exercise Form to the Company by electronic mail or otherwise, Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been Exercised, irrespective of the date such Warrant Shares are credited to Holder’s or its designee’s Depository Trust Company (“DTC”) account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be; provided, however, that in the event an Exercise Form in respect of a Cashless

4

Major Exercise is delivered prior to the occurrence of the applicable Major Transaction, Holder shall be deemed to have become the holder of record of the shares issuable upon such exercise immediately prior to the consummation of such Major Transaction and the Date of Exercise shall in such event be deemed to have occurred on the date of the occurrence of the Major Transaction. Holder shall not be required to physically surrender this Warrant to the Company until Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days following the date the final Exercise Form is delivered to the Company. Execution and delivery of an Exercise Form with respect to a partial Exercise shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares.

(c) Delivery of Common Stock Upon Exercise . Within the earlier of (x) two (2) Trading Days and (y) the number of Trading Days comprising the Standard Settlement Period after any Date of Exercise (but, in the case of a Cash Exercise, within two (2) Business Days following the Company’s receipt of the full Exercise Price, if later) or in the case of a Cashless Default Exercise (as defined in Section 5(b) below), within the period provided in Section 3(c), as applicable (the “Delivery Period”), the Company shall issue and deliver (or cause its transfer agent (the “Transfer Agent”) to issue and deliver) in accordance with the terms hereof to or upon the order of Holder that number of shares of Common Stock (“Exercise Shares”) for the portion of this Warrant exercised as shall be determined in accordance herewith. Upon the Exercise of this Warrant or any part hereof, the Company shall, at its own cost and expense, take all necessary action, including obtaining and delivering an opinion of counsel, to assure that the Transfer Agent shall issue stock certificates in the name of Holder (or its nominee) or such other persons as designated by Holder and in such denominations as Holder shall specify at Exercise, representing the number of shares of Common Stock issuable upon such Exercise. The Company warrants that no instructions other than these instructions have been or will be given to the Transfer Agent and that, unless waived by Holder, this Warrant and the Exercise Shares will be free-trading, and freely transferable, and will not contain or be subject to a legend (or be subject to any stop transfer instruction) restricting the resale or transferability of the Exercise Shares if the Unrestricted Conditions (as defined below) are met.

The Company shall be responsible for paying all present or future stamp, court or documentary, intangible, recording, filing or similar taxes that arise from any payment or issuance made under, from the execution, delivery, performance or enforcement of, or otherwise with respect to, this Warrant.

(d) Delivery Failure . In addition to any other remedies which may be available to Holder, in the event that the Company fails for any reason to effect delivery of the Exercise Shares by the end of the Delivery Period (a “Delivery Failure”), Holder will be entitled to revoke all or part of the relevant Exercise by delivery of a notice to such effect to the Company whereupon the Company and Holder shall each be restored to their respective positions immediately prior to the delivery of such notice of revocation, except that the Failure Payments under Section 10(b) shall be payable through the date such notice of revocation is given to the Company.

5

(e) Legends .

(i) Restrictive Legend . Holder understands that until such time as this Warrant, the Exercise Shares and the Failure Payment Shares (as defined below) have been registered under the Securities Act or otherwise may be sold pursuant to Rule 144 or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, this Warrant, the Exercise Shares and the Failure Payment Shares, as applicable, may bear a restrictive legend in substantially the following form (and a stop-transfer order consistent therewith may be placed against transfer of the certificates for such securities):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, EXCEPT PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING PURSUANT TO SECTION 4(A)(7) OF THE SECURITIES ACT OR RULE 144 UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION OR GUIDANCE, SUCH AS A SO-CALLED “4[(a)](1) AND A HALF” SALE.” NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

(ii) Removal of Restrictive Legends . This Warrant and the certificates (or electronic book entries, if applicable) evidencing the Exercise Shares and the Failure Payment Shares, as applicable, shall not contain or be subject to any legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)) or be subject to any stop-transfer instructions: (A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering the sale or resale of such security is effective under the Securities Act, or (B) following any sale of such Warrant, Exercise Shares and/or Failure Payment Shares pursuant to Rule 144, or (C) if such Warrant, Exercise Shares and/or Failure Payment Shares are eligible for sale under Rule 144(b)(1), or (D) at any time on or after the date hereof on which Holder’s holding period for purposes of Rule 144 under the Securities Act and subsection (d)(3)(iii) thereof with respect to such Warrant, Exercise Shares and/or Failure Payment Shares is at least six (6) months and Holder certifies that it is not an Affiliate of the Company, or (E) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective Date, or at such other time as any of the Unrestricted Conditions have been met, if required by the Transfer Agent to effect the issuance of this Warrant, the Exercise Shares or the Failure Payment Shares, as applicable, without a restrictive legend or removal of the legend hereunder. If any of the Unrestricted Conditions are met at the

6

time of issuance of this Warrant, the Exercise Shares or the Failure Payment Shares, then such Warrant, Exercise Shares or Failure Payment Shares, as applicable, shall be issued free of all legends and stop-transfer instructions. The Company agrees that following the Effective Date, or at such time as the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 2(e), it will, no later than the earlier of (x) two (2) Trading Days and (y) the number of Trading Days comprising the Standard Settlement Period following the delivery (the “Unlegended Shares Delivery Deadline”) by Holder to the Company or the Transfer Agent of this Warrant and a certificate representing Exercise Shares and/or Failure Payment Shares, as applicable, issued with a restrictive legend, deliver or cause to be delivered to Holder this Warrant and/or a certificate (or electronic transfer) representing such shares that is free from all restrictive and other legends (and stop transfer instructions). For purposes hereof, “Effective Date” shall mean the date that the first Registration Statement that the Company is required to file pursuant to the Registration Rights Agreement has been declared effective by the SEC.

(iii) Sale of Unlegended Shares . Holder agrees that the removal of the restrictive legend from this Warrant and any certificates representing securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that Holder will sell this Warrant or any Exercise Shares and/or any Failure Payment Shares, as applicable, pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein.

(f) Cancellation of Warrant . This Warrant shall be canceled upon the full Exercise of this Warrant, and, as soon as practical after the Date of Exercise, Holder shall be entitled to receive Common Stock for the number of shares purchased upon such Exercise of this Warrant, and if this Warrant is not Exercised in full, Holder shall be entitled to receive a new Warrant (containing terms identical to this Warrant) representing any unexercised portion of this Warrant in addition to such Common Stock; provided, however, as set forth in Section 2(b), Holder shall not be required to physically surrender this warrant if the Warrant is not Exercised in full.

(g) Holder of Record . Each person in whose name any Warrant for shares of Common Stock is issued shall, for all purposes, be deemed to be Holder of record of such shares on the Date of Exercise, irrespective of the date of delivery of the Common Stock purchased upon the Exercise of this Warrant. Prior to the exercise of this Warrant, nothing in this Warrant shall be construed as conferring upon Holder any rights as a stockholder of the Company.

(h) Delivery of Electronic Shares . In lieu of delivering physical certificates representing the Common Stock issuable upon Exercise or legend removal, or representing Failure Payment Shares, upon written request of Holder, the Company shall use its best efforts to cause the Transfer Agent to electronically transmit the Common Stock issuable upon Exercise to Holder by crediting the account of Holder’s prime broker with DTC through its Deposit/Withdrawal at Custodian (DWAC) system. The time periods for delivery and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates.

7

(i) Buy-In . In addition to any other rights or remedies available to Holder hereunder or otherwise at law or in equity, if the Company fails to cause its Transfer Agent to deliver to Holder a certificate or certificates, or electronic shares through DWAC, representing the Exercise Shares pursuant to an Exercise on or before the last day of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date Holder is required by its broker to purchase (in an open market transaction or otherwise) or Holder or Holder’s brokerage firm otherwise purchases shares of Common Stock to deliver in satisfaction of a sale by Holder of the Exercise Shares which Holder was entitled to receive upon such Exercise (a “Buy-In”), then the Company shall (1) pay in cash to Holder the amount by which (x) Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Exercise Shares that the Company was required to deliver to Holder in connection with the Exercise at issue by (B) the price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of Holder, either reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such Exercise was not honored (and refund the Exercise Price therefor, to the extent paid by Holder, and/or reinstate the principal amount of any indebtedness used to satisfy the applicable Exercise Price) or deliver to Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its Exercise and delivery obligations hereunder. For example, if Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted Exercise to cover the sale of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay Holder $1,000. Holder shall provide the Company written notice indicating the amounts payable to Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon Exercise of the Warrant as required pursuant to the terms hereof.

(j) HSR Submissions. If Holder determines that, in connection with the exercise of this Warrant, it and the Company are required to file Premerger Notification Reports with the Federal Trade Commission (the “FTC”) and the United States Department of Justice (“DOJ”) and observe the Waiting Period under the Hart-Scott Rodino Antitrust Improvements Act of 1976, as amended, and the related rules and regulations promulgated thereunder (collectively, the “HSR Act”), the Company agrees to (i) cooperate with Holder in Holder’s preparing and making such submission and any responses to inquiries of the FTC and DOJ; (ii) prepare and make any submission required to be filed by the Company under the HSR Act and respond to inquiries of the FTC and DOJ in connection therewith; and (iii) reimburse Holder for the cost of the required filing fee for Holder’s submission under the HSR Act. For the avoidance of doubt, Holder shall bear all of its other costs and expenses in connection with such submission, including any attorneys’ fees associated therewith.

3. Payment of Warrant Exercise Price for Cash Exercise or Cashless Exercise; Cashless Major Exercise and Cashless Default Exercise .

(a) Exercise Price . The exercise price shall initially equal $6.61 per share, subject to adjustment pursuant to the terms hereof (as so adjusted, the “Exercise Price”), including but not limited to Section 5 below.

Payment of the Exercise Price may be made by any of the following, or a combination thereof, at the election of Holder:

(i) Cash Exercise : Holder may exercise this Warrant in cash, bank or cashier’s check or wire transfer (a “Cash Exercise”);

(ii) Cashless Exercise : In lieu of paying all or any portion of the Exercise Price in cash, Holder, at its option, may exercise this Warrant (in whole or in part) on a cashless basis by making appropriate notation on the applicable Exercise Form, in which event the Company shall issue Holder a number of shares of Common Stock computed using the following formula (a “Cashless Exercise”):

X = Y (A-B)/A

where: X = the number of shares of Common Stock to be issued to Holder.

Y = the number of shares of Common Stock for which this Warrant is being Exercised.

A = the Market Price of one (1) share of Common Stock (for purposes of this Section 3(a)(ii), where “Market Price,” as of any date, means the arithmetic average of the Volume Weighted Average Price (as defined below) of the Company’s Common Stock on each of the ten (10) consecutive Trading Days immediately preceding the date in question).

B = the Exercise Price.

As used herein, the “ Volume Weighted Average Price ” for any security as of any date means the volume weighted average sale price on the NasdaqGS as reported by, or based upon data reported by, Bloomberg Financial Markets or an equivalent, reliable reporting service mutually acceptable to and hereafter designated by the Holder and the Company (“ Bloomberg ”), or, if the NasdaqGS is not the principal trading market for such security, the volume weighted average sale price of such security on the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg, or, if no volume weighted average sale price is reported for such security, then the last closing trade price of such security as reported by Bloomberg, or, if no last closing trade price is reported for such security by Bloomberg, the average of the bid prices of any market makers for such security on the OTC Bulletin Board, the OTCQX Market, the OTCQB Market or the “pink” market of OTC Markets Group. If the Volume Weighted Average Price cannot be calculated for such security on such date in the manner provided above, the Volume Weighted Average Price shall be the fair market value as determined by the Company and the Holder. In the event that a Stock Event is

9

consummated during any period for which the arithmetic average of the Volume Weighted Average Prices is to be determined (under this Section or otherwise), the Volume Weighted Average Price for all Trading Days during such period prior to the effectiveness of the Stock Event shall be appropriately adjusted to reflect such Stock Event.

(iii) Note Exchange Exercise : In lieu of paying all or any portion of the Exercise Price in cash, Holder, at its option, may exercise this Warrant (in whole or in part) through a reduction of an amount of principal outstanding under any First Out Waterfall Notes (as defined in the Facility Agreement) in accordance with Section 2.3(b) of the Facility Agreement, then held by Holder (a “Note Exchange Exercise”)

For purposes of Rule 144 and subsection (d)(3)(ii) thereof, it is intended, understood and acknowledged that (x) this Warrant shall be deemed to have been acquired on April 3, 2017 (the date the First Out Waterfall Notes were originally issued), and (y) the shares of Common Stock issuable upon Exercise of this Warrant in a Cashless Exercise (including a Cashless Major Exercise or Cashless Default Exercise) transaction or a Note Exchange Exercise transaction shall be deemed to have been acquired on April 3, 2017. Accordingly, (A) upon any such Exercise, the Rule 144 holding period for the shares of Common Stock issued thereupon shall be in excess of one (1) year, and (B) provided that Holder is not an “affiliate” (as defined in Rule 144 under the Securities Act) of the Company on the date of such Exercise (which the Company shall assume unless advised otherwise in writing by Holder), an Unrestricted Condition shall be satisfied with respect to the shares of Common Stock issued thereupon and such shares will be freely transferable, without restriction or limitation (including any volume limitation or current public information requirement) under Federal or state securities laws, pursuant to Rule 144 under the Securities Act, and will not contain or be subject to a legend or stop transfer order restricting the resale or transferability of thereof.

As provided in Section 2(b), Holder shall only be required to physically surrender this Warrant in the event that Holder is exercising this Warrant in full.

(b) Cashless Major Exercise. To the extent Holder shall exercise this Warrant as a Cashless Major Exercise pursuant to Section 5(b)(i) and 5(b)(iii) below, Holder shall send to the Company (in any manner permitted under Section 2(a)) the Exercise Form indicating that Holder is exercising this Warrant (or any portion thereof) pursuant to a Cashless Major Exercise, in which event the Company shall issue a number of shares of Common Stock equal to the Black-Scholes Value of the Warrant (or such applicable portion being exercised) divided by the closing price of the Common Stock on the principal securities exchange or other securities market on which the Common Stock is then traded on the Trading Day immediately preceding the date on which the applicable Major Transaction is consummated, or, if in respect of a Cashless Major Exercise made after the date of consummation of the applicable Major Transaction, on the Trading Day immediately preceding the date on which the exercise form in respect of such Cashless Major Exercise is delivered. As provided in Section 2(b), Holder shall only be required to physically surrender this Warrant in the event that Holder is exercising this Warrant in full. Holder shall be permitted to make successive Cashless Major Exercises and send successive Exercise Forms in respect of a Cashless Major Exercise from time to time at any time during the Cashless Major Exercise Period.

10

(c) Cashless Default Exercise . To the extent Holder exercises this Warrant as a Cashless Default Exercise pursuant to Section 11(b)(i) below, Holder shall send to the Company (in any manner permitted under Section 2(a)) the Exercise Form indicating that Holder is exercising this Warrant pursuant to a Cashless Default Exercise, in which event the Company shall issue to Holder, within five (5) Trading Days of the applicable Default Notice, a number of shares of Common Stock (which shares shall be valued at the closing price of the Common Stock on the principal securities exchange or other securities market on which the Common Stock is then traded on the Trading Day immediately preceding the date on which the Exercise Form in respect of such Cashless Default Exercise is delivered) equal to the Black-Scholes Value of the remaining unexercised portion of this Warrant (or such portion thereof subject to such exercise) as of the date of such Default Notice (or in the case of an Event of Default referred to in Section 11(a)(vi), on the Trading Day immediately preceding the date the dividend or distribution is declared or, if not first declared, is paid). As provided in Section 2(b), the Holder shall be permitted to make successive Cashless Default Exercises and send successive Exercise Forms in respect of a Cashless Default Exercise, from time to time at any time from and after the date of the applicable Default Notice through the Exercise Period of this Warrant.

(d) Dispute Resolution . In the case of a dispute as to the determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock or the arithmetic calculation of the Exercise Price, Market Price or the Successor Major Transaction Consideration, or the number of shares issuable upon a Cashless Major Exercise, the Company shall submit the disputed determinations or arithmetic calculations via electronic mail within two (2) Business Days of receipt, or deemed receipt, of the Exercise Form or Major Transaction Early Termination Notice, or other event giving rise to such dispute, as the case may be, to Holder. If Holder and the Company are unable to agree upon such determination or calculation within two (2) Business Days of such disputed determination or arithmetic calculation being submitted to Holder, then the Company shall, within two (2) Business Days submit via electronic mail (i) the disputed determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock to an independent, reputable investment bank selected by the Company and approved by Holder, which approval shall not be unreasonably withheld, or (ii) the disputed arithmetic calculation of the Exercise Price, Market Price, any Successor Major Transaction Consideration or number of shares issuable upon a Cashless Major Exercise to the Company’s independent, outside registered public accountants. The Company shall use its reasonable best efforts to cause the investment bank or the accountants, as the case may be, to perform the determinations or calculations and notify the Company and Holder of the results no later than five (5) Trading Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountants’ determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error, and the Company and Holder shall each pay one half of the fees and costs of such investment banker or accountant. Notwithstanding the existence of a dispute contemplated by this paragraph, if requested by Holder, the Company shall issue to Holder the Exercise Shares not in dispute in accordance with the terms hereof.

4. Transfer and Registration .

(a) Transfer Rights . Subject to the provisions of Section 8 of this Warrant, this Warrant may be transferred on the books of the Company, in whole or in part, in person or by attorney, upon

11

surrender of this Warrant properly completed and endorsed. This Warrant shall be canceled upon such surrender and, as soon as practicable thereafter, the person to whom such transfer is made shall be entitled to receive a new Warrant or Warrants as to the portion of this Warrant transferred, and Holder shall be entitled to receive a new Warrant as to the portion hereof retained.

(b) Registrable Securities . The Common Stock issuable upon the Exercise of this Warrant entitles Holder (and applicable assignees or transferees of such Common Stock) to registration and other rights pursuant to the Registration Rights Agreement.

5. Adjustments Upon Certain Events .

(a) Recapitalization or Reclassification . If the Company shall at any time effect a stock split, payment of stock dividend, recapitalization, reclassification or other similar transaction of such character that the shares of Common Stock shall be changed into or become exchangeable for a larger or smaller number of shares, then upon the effective date thereof, the number of shares of Common Stock which Holder shall be entitled to purchase upon Exercise of this Warrant, shall be increased or decreased, as the case may be, in direct proportion to the increase or decrease in the number of shares of Common Stock by reason of such stock split, payment of stock dividend, recapitalization, reclassification or similar transaction, and the Exercise Price shall be, in the case of an increase in the number of shares, proportionally decreased and, in the case of decrease in the number of shares, proportionally increased. The Company shall give Holder the same notice it provides to holders of Common Stock of any transaction described in this Section 5(a).

(b) Rights Upon Major Transaction .

(i) Major Transaction . In the event that a Major Transaction occurs, then (1) in the case of a Successor Major Transaction, Holder, at its option, may elect to cause the conversion of this Warrant (a “Successor Major Transaction Conversion”), in whole or in part, into the right to receive the Successor Major Transaction Consideration, upon consummation of the Major Transaction, and (2) in the case of all other Major Transactions, Holder shall have the right to exercise this Warrant (or any portion thereof), at any time and from time to time following the occurrence of such event, as a Cashless Major Exercise. In the event Holder shall not have exercised any of its rights under clauses (1) or (2) above within the applicable time periods set forth herein, then the Major Transaction shall be treated as an Assumption (as defined below) in accordance with Section 5(b)(ii) below unless Holder waives its rights under this Section 5(b) with respect to such Major Transaction. Each of the following events shall constitute a “Major Transaction”:

(A) a consolidation, merger, exchange of shares, recapitalization, reorganization, business combination or other similar event, (1) following which the holders of Common Stock immediately preceding such consolidation, merger, exchange, recapitalization, reorganization, combination or event either (a) no longer hold a majority of the shares of Common Stock or (b) no longer have the ability to elect a majority of the board of directors of the Company or (2) as a result of which shares of Common Stock shall be changed into (or the shares of Common Stock become entitled to receive) the same or a different

12

number of shares of the same or another class or classes of stock or securities of the Company or another entity (collectively, a “Change of Control Transaction”);

(B) the sale or transfer, in one transaction or a series of related transactions, of (I) all or substantially all of the assets of the Company (including, for the avoidance of doubt, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole) to any Person other than a wholly-owned subsidiary of the Company or (II) assets of the Company (including, for the avoidance of doubt, all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole) for a purchase price equal to more than 50% of the Equity Value (as defined below) of the Company. For purposes of this clause (B), “Equity Value” shall mean (I) the product of (x) the number of issued and outstanding shares of Common Stock on the date the Company delivers the Major Transaction Notice (defined below) multiplied by (y) the per share closing price of the Common Stock on such date on the NasdaqGS as reported by, or based upon data reported by, Bloomberg or, if the NasdaqGS is not the principal trading market for such security, the closing sale price of such security on the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg;

(C) a purchase, tender or exchange offer made to the holders of outstanding shares of Common Stock, such that following such purchase, tender or exchange offer a Change of Control Transaction shall have occurred;

(D) the liquidation, bankruptcy, insolvency, dissolution or winding-up (or the occurrence of any analogous proceeding) affecting the Company;

(E) the shares of Common Stock cease to be listed, traded or publicly quoted on the NasdaqGS and are not promptly re-listed or requoted on the New York Stock Exchange, the NYSE American, the NASDAQ Global Market or the NASDAQ Capital Market; or

(F) the Common Stock ceases to be registered under Section 12 of the Exchange Act.

(ii) Assumption. Any assumption of Company obligations under this paragraph shall be referred to herein as an “Assumption.” Unless otherwise provided in writing by Holder, the Company shall not consummate a Major Transaction in which the Company is not the surviving entity or as a result of which the Company has a new Parent Entity, unless (A) each Person acquiring the Company’s assets or Common Stock (or Parent Entity thereof, as applicable), or any other successor entity resulting from such Major Transaction (in each case, a “Successor Entity”), assumes in writing all of the obligations of the Company under this Warrant, the Facility Agreement (but, other than with respect to the Company’s obligations pursuant to Section 5.1(e) and 5.1(p) of the Facility Agreement and the other provisions of the Facility Agreement that

13

expressly survive the repayment of the Loans (which shall be assumed in any Assumption), only if there are outstanding Loans under the Facility Agreement immediately following the consummation of the Major Transaction) and the Registration Rights Agreement in accordance with the provisions of this Section 5(b)(ii) pursuant to written agreements in form and substance reasonably satisfactory to Holder and approved by Holder prior to the consummation of such Major Transaction (such approval not to be unreasonably withheld or delayed), including agreements to deliver to Holder in exchange for its Warrants a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Warrants, that, among other things, (1) is exercisable for the appropriate number of shares of the Successor Entity’s capital stock (without regard to the 4.985% Cap or any other restriction or limitation on exercise, provided that such instrument shall contain a limitation on exercise comparable to that contained in the second paragraph of Section 1 of this Warrant); (2) has an exercise price similar to the then-effective Exercise Price (taking into account any conversion or exchange ratio applicable to the Common Stock in the Major Transaction) and exercise price adjustment provisions similar to those in the Warrants; (3) entitles Holder to such additional securities or other consideration as Holder would be entitled pursuant to Section 5(b)(i) in connection with the Major Transaction; and (4) provides for registration rights similar to those provided by the Registration Rights Agreement, in each case reasonably satisfactory to Holder, and (B) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. For the avoidance of doubt, Holder’s reasonable satisfaction referred to in the immediately preceding sentence shall be construed only to apply to confirmation that the warrant or other comparable security and registration rights agreement delivered to Holder upon an assumption hereunder shall conform to the requirements of this Section 5(b)(ii), and this Section 5(b)(ii) shall not be construed as granting consent or approval rights to Holder with respect to the terms of such Major Transaction or to permit Holder to demand any additional consideration in respect of this Warrant other than as provided herein. Upon the occurrence of any Major Transaction, any Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Major Transaction, the provisions of this Warrant and the Registration Rights Agreement referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Major Transaction, the Successor Entity shall deliver to Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the consummation of the Major Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the Warrants prior to such Major Transaction, such shares of publicly traded common stock (or their equivalent) of the Successor Entity, as adjusted in accordance with the provisions of this Warrant. The provisions of this Section shall apply similarly and equally to successive Major Transactions and shall be applied without regard to any limitations on the exercise of this Warrant other than any applicable beneficial ownership limitations.

(iii) Major Transaction Notice; Major Transaction Early Termination Right; Notice of Cashless Major Exercise. At least thirty (30) days prior to the consummation of any Major Transaction, but, in any event, within five (5) Trading Days following the first to occur of (x) the date of the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, or (y) the day following the public announcement of such Major

14

Transaction if such announcement is made on and after 4:00 p.m., New York City time, the Company shall deliver written notice thereof via electronic mail and overnight courier to Holder (a “Major Transaction Notice”). At any time during the period beginning after Holder’s receipt of a Major Transaction Notice in respect of a Successor Major Transaction and ending five (5) Trading Days prior to the consummation of such Major Transaction (the “Early Termination Period”), Holder may elect a Successor Major Transaction Conversion by delivering written notice thereof (“Major Transaction Early Termination Notice”) to the Company, which Major Transaction Early Termination Notice shall indicate the portion of the Warrant (with reference to the number of shares of Common Stock issuable upon a Cash Exercise of such portion, without regard to the 4.985% Cap) that Holder is electing to be treated as a Successor Major Transaction Conversion. The portion of this Warrant subject to early termination pursuant to this Section 5(b)(iii), shall be converted into the right to receive the Successor Major Transaction Consideration

To the extent Holder shall elect to effect a Cashless Major Exercise in respect of a Major Transaction, Holder shall deliver its Exercise Form in accordance with Section 3(b), at any time and from time to time following receipt by Holder of the Major Transaction Notice until the later of (x) the last day of the Exercise Period and (y) the one-year anniversary of the applicable Major Transaction (the “Cashless Major Exercise Period”). For the avoidance of doubt, Holder shall be permitted to make successive Cashless Major Exercises and send successive Exercise Forms in respect of a Cashless Major Exercise from time to time at any time during the Cashless Major Exercise Period.

(iv) Escrow; Payment of Successor Major Transaction Consideration . Following the receipt of a Major Transaction Early Termination Notice in respect of a Successor Major Transaction from Holder, the Company shall not effect a Successor Major Transaction with respect to which Holder has elected a Successor Major Transaction Conversion unless either (A) it obtains, as a condition precedent to such Major Transaction, the written agreement of the Successor Entity that payment of the Successor Major Transaction Consideration shall be made to Holder concurrently with consummation of such Successor Major Transaction, or (B) it shall place the Successor Major Transaction Consideration into an escrow account with an independent escrow agent, and shall instruct the escrow agent to deliver the Successor Major Transaction Consideration to Holder, concurrently with the consummation of the Major Transaction. Notwithstanding clauses (A) and (B) above, Holder shall be treated on a pari passu basis with, and shall not have priority to payments to, the holders of Common Stock in connection with a Major Transaction. For purposes of determining the amount required to be placed in escrow pursuant to the provisions of this subsection (iv) and without affecting the amount of the actual Successor Major Transaction Consideration, the calculation of the price referred to in clause (1) of the first column of Schedule 1 hereto with respect to Stock Price shall be determined based on the Closing Market Price (as defined on Schedule 1) of the Common Stock on the Trading Day immediately preceding the date that the Successor Major Transaction Consideration is deposited with the escrow agent.

(v) Injunction . Following the receipt of a Major Transaction Early Termination Notice from Holder, in the event that the Company attempts to consummate a Successor Major Transaction without either (1) placing the Successor Major Transaction Consideration in escrow in accordance with subsection (iv) above, or (2) obtaining the written agreement of the Successor

15

Entity as described in subsection (iv) above, Holder shall have the right to apply for an injunction in any state or federal court sitting in the City of New York, borough of Manhattan to prevent the closing of such Major Transaction until the Successor Major Transaction Consideration is delivered to Holder.

An early termination required by this Section 5(b) shall be made in accordance with the provisions of Section 12. To the extent an early termination required by this Section 5(b) is deemed or determined by a court of competent jurisdiction to be prepayments of the Warrant by the Company, such early termination shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, until the Successor Major Transaction Consideration is paid in full, this Warrant may be exercised, in whole or in part, by Holder into shares of Common Stock, or in the event the date of any Exercise is after the consummation of the Major Transaction, shares of publicly traded common stock (or their equivalent) of the Successor Entity pursuant to Section 5(b). The parties hereto agree that in the event of the Company’s early termination of any portion of the Warrant under this Section 5(b), Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for Holder. Accordingly, any premium due under this Section 5(b) is intended by the parties to be, and shall be deemed, a commercially reasonable estimate of Holder’s actual loss of its investment opportunity and not as a penalty.

(c) Exercise Price Adjusted . As used in this Warrant, the term “Exercise Price” shall mean the purchase price per share specified in Section 3(a) of this Warrant, until the occurrence of an event stated in this Section 5 or otherwise set forth in this Warrant, and thereafter shall mean said price as adjusted from time to time in accordance with the provisions of said subsection. No adjustment made pursuant to any provision of this Section 5 shall have the net effect of increasing the aggregate Exercise Price payable hereunder or, except as expressly provided in Section 5(a), otherwise increasing the Exercise Price.

(d) Adjustments: Additional Shares, Securities or Assets . In the event that at any time, as a result of an adjustment made pursuant to this Section 5 or otherwise, Holder shall, upon Exercise of this Warrant, become entitled to receive shares and/or other securities or assets (other than Common Stock) then, wherever appropriate, all references herein to shares of Common Stock shall be deemed to refer to and include such shares and/or other securities or assets; and thereafter the number of such shares and/or other securities or assets shall be subject to adjustment from time to time in a manner and upon terms as nearly equivalent as practicable to the provisions of this Section 5.

(e) Notice of Adjustments . Whenever the Exercise Price and/or number or type of securities issuable upon Exercise is adjusted pursuant to the terms of this Warrant, the Company shall promptly mail to Holder a notice (an “Exercise Price Adjustment Notice”) setting forth the Exercise Price and/or number or type of securities issuable upon Exercise after such adjustment and setting forth a statement of the facts requiring such adjustment. The Company shall, upon the written request at any time of Holder, furnish to Holder a like Warrant setting forth (i) such adjustment or readjustment, (ii) the Exercise Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon Exercise of the Warrant. For purposes of clarification, whether or not

16

the Company provides an Exercise Price Adjustment Notice pursuant to this Section 5(e), upon the occurrence of any event that leads to an adjustment of the Exercise Price, Holder would be entitled to receive a number of Exercise Shares based upon the new Exercise Price, as adjusted, for exercises occurring on or after the date of such adjustment, regardless of whether Holder accurately refers to the adjusted Exercise Price in the Exercise Form.

6. Fractional Interests .

No fractional shares or scrip representing fractional shares shall be issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, Holder may purchase only a whole number of shares of Common Stock. If, on Exercise of this Warrant, Holder would be entitled to a fractional share of Common Stock or a right to acquire a fractional share of Common Stock, such fractional share shall be disregarded and the number of shares of Common Stock issuable upon Exercise shall be the next higher whole number of shares.

7. Reservation of Shares .

From and after the date hereof, the Company shall at all times reserve for issuance such number of authorized and unissued shares of Common Stock (or other securities substituted therefor as herein above provided) as shall be sufficient for the Exercise of this Warrant and payment of the Exercise Price. If at any time the number of shares of Common Stock authorized and reserved for issuance is below the number of shares sufficient for the Exercise of this Warrant (a “Share Authorization Failure”) (based on the Exercise Price in effect from time to time), the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations under this Section 7, in the case of an insufficient number of authorized shares, and using its best efforts to obtain stockholder approval of an increase in such authorized number of shares. The Company covenants and agrees that upon the Exercise of this Warrant, all shares of Common Stock issuable upon such Exercise shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive rights, rights of first refusal or similar rights of any Person. The Company covenants and agrees that all shares of Common Stock issuable upon Exercise of this Warrant shall be approved for listing on the NasdaqGS, or, if the NasdaqGS is not the principal trading market for the Common Stock, such principal market on which the Common Stock is traded or listed.

8. Restrictions on Transfer .

(a) Registration or Exemption Required . This Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Section 4(a)(2) of the Securities Act and Rule 506 thereunder and exempt from registration or qualification under applicable state securities (or “blue sky”) laws. None of the Warrant, the Exercise Shares or Failure Payment Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws, including Rule 144 under the Securities Act, Section 4(a)(7) of the Securities Act or a so-called “4[(a)](1) and a half” transaction.

(b) Assignment . Subject to Section 8(a), Holder may sell, transfer, assign, pledge, or otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a written notice to the

17

Company, substantially in the form of the Assignment attached hereto as Exhibit  B , indicating the Person or Persons to whom the Warrant shall be assigned and the respective number of warrants to be assigned to each assignee. The Company shall effect the assignment within three (3) Business Days of its receipt of a completed and executed form of Assignment (the “Transfer Delivery Period”), and shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of like tenor and terms entitling Holder to purchase the appropriate number of shares. This Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns of Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or transfer is a so called “4[(a)](1) and half” transaction, the parties hereto agree that a legal opinion from outside counsel for Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit  C shall be the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4[(a)](1) and half” transaction.

9. Noncircumvention .

The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.

10. Events of Failure; Definition of Black Scholes Value .

(a) Definition.

The occurrence of each of the following shall be considered to be an “Event of Failure.”

(i) A Delivery Failure occurs, where a “Delivery Failure” shall be deemed to have occurred if the Company fails to use its best efforts to deliver Exercise Shares to Holder within any applicable Delivery Period (other than due to the limitation contained in the second paragraph of Section 1);

(ii) A Legend Removal Failure occurs, where a “Legend Removal Failure” shall be deemed to have occurred if the Company fails to use its best efforts to issue this Warrant and/or Exercise Shares without a restrictive legend, or fails to use it best efforts to remove a restrictive legend, when and as required under Section 2(e) hereof;

(iii) a Transfer Delivery Failure occurs, where a “Transfer Delivery Failure” shall be deemed to have occurred if the Company fails to use its best efforts to deliver a Warrant within any applicable Transfer Delivery Period; and

(iv) a Registration Failure (as defined below).

18

For purpose hereof, “Registration Failure” means that (A) the Company fails to file with the SEC on or before the Filing Deadline (as defined in the Registration Rights Agreement) any Registration Statement required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, (B) the Company fails to use its reasonable best efforts to obtain effectiveness with the SEC, prior to the Registration Deadline (as defined in the Registration Rights Agreement), and if such Registration Statement does not become effective prior to the Registration Deadline, as soon as possible thereafter, of any Registration Statement (as defined in the Registration Rights Agreement) that is required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, or fails to use its reasonable best efforts to keep such Registration Statement current and effective as required in Section 3 of the Registration Rights Agreement, (C) the Company fails to file any additional Registration Statement required to be filed pursuant to Section 2(a)(ii) of the Registration Rights Agreement on or before the Additional Filing Deadline (as defined in the Registration Rights Agreement) or fails to use its reasonable best efforts to cause such new Registration Statement to become effective on or before the Additional Registration Deadline (as defined in the Registration Rights Agreement), and if such effectiveness does not occur within such period, as soon as possible thereafter, (D) the Company fails to file any amendment to any Registration Statement, or any additional Registration Statement required to be filed pursuant to Section 3(b) of the Registration Rights Agreement within thirty (30) days of the applicable Registration Trigger Date (as defined in the Registration Rights Agreement), or fails to use its reasonable best efforts to cause such amendment and/or new Registration Statement to become effective within ninety (90) days of the applicable Registration Trigger Date, and, if such effectiveness does not occur within such period, as soon as possible thereafter, (E) any Registration Statement required to be filed under the Registration Rights Agreement, after its initial effectiveness and during the applicable Registration Period (as defined in the Registration Rights Agreement), lapses in effect or, other than on a day during an Allowable Grace Period (as defined in the Registration Rights Agreement), sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) cannot otherwise be made thereunder (whether by reason of the Company’s failure to amend or supplement the prospectus included therein in accordance with the Registration Rights Agreement, the Company’s failure to file and use its reasonable best efforts to obtain effectiveness with the SEC of an additional Registration Statement or amended Registration Statement required pursuant to Section 2(a)(ii) or 3(b) of the Registration Rights Agreement, as applicable, or otherwise), or (F) the Company fails to provide a commercially reasonable written response to any comments to any Registration Statement submitted by the SEC within twenty-five (25) days of the date that such SEC comments are received by the Company.

(b) Failure Payments; Black-Scholes Determination. The Company understands that any Event of Failure (as defined above) could result in economic loss to Holder. In the event that any Event of Failure occurs, as compensation to Holder for such economic loss, the Company agrees to pay to Holder an amount payable, at the Company’s option, either (i) in cash or (ii) in shares of Common Stock that are valued for these purposes at the Volume Weighted Average Price on the date of such calculation (“Failure Payments” and such shares, “Failure Payment Shares”), in each case equal to the total economic loss of Holder determined on a commercially reasonable basis in connection with such Event of Failure for the relevant period (as recalculated on the first Business Day of each month thereafter for as long as Failure Payments shall continue to accrue) from the date of such Event of Failure until the Event of Failure is cured; provided, however, that in the event the Company elects to make Failure Payments in Failure Payment Shares, the

19

Company shall issue, and Holder shall only receive, up to such number of shares of Common Stock in respect of Failure Payments such that Holder and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein) shall not collectively beneficially own greater than 4.985% of the total number of shares of Common Stock of the Company then issued and outstanding, and the balance of such Failure Payments shall be paid in cash. For purposes of clarification, it is agreed and understood that Failure Payments shall continue to accrue following any Event of Default until the applicable Default Amount is paid in full. The Company shall satisfy any Failure Payments under this Section pursuant to Section 10(c) below. Failure Payments are in addition to any Shares that Holder is entitled to receive upon Exercise of this Warrant.

(c) Payment of Accrued Failure Payments. The Failure Payments and Failure Payment Shares representing accrued Failure Payments for each Event of Failure shall be paid or issued and delivered, as the case may be, on or before the fifth (5th) Business Day of each month following a month in which Failure Payments accrued. Nothing herein shall limit Holder’s right to pursue actual damages (to the extent in excess of the Failure Payments) for the Company’s Event of Failure, and Holder shall have the right to pursue all remedies available at law or in equity (including a decree of specific performance and/or injunctive relief). Notwithstanding the above, if a particular Event of Failure results in an Event of Default pursuant to Section 11 hereof, then the Failure Payment, for that Event of Failure only, shall be considered to have been satisfied upon payment to Holder of an amount equal to the greater of (i) the Failure Payment, or (ii) the Default Amount, payable in accordance with Section 11.

(d) Maximum Interest Rate. Nothing contained herein or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest or dividends required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Company to Holder and thereby refunded to the Company.

11. Default .

(a) Events Of Default . Each of the following events shall be considered to be an “Event of Default,” unless waived by Holder:

(i) Failure To Effect Registration. With respect to all Registration Failures, a Registration Failure occurs and remains uncured for a period of more than forty-five (45) days (or sixty (60) days in the case where the Company (i) has, by the Filing Deadline (as defined the Registration Rights Agreement) filed a Registration Statement (as defined in the Registration Rights Agreement) covering this Warrant and the number of shares required by the Registration Rights Agreement, and (ii) has responded in writing to any comments to the Registration Statement that the Company has received from the SEC, within ten (10) Business Days of such receipt, and nevertheless the SEC has not declared effective a Registration Statement covering the this

20

Warrant and the Shares by the Registration Deadline (as defined in the Registration Rights Agreement)), and such Registration Failure relates solely to the Company’s failure to have the Registration Statement declared effective by the Registration Deadline (as defined in the Registration Rights Agreement) and with respect to a Registration Failure provided in clause (E) of the definition of “Registration Failure,” such Registration Failure occurs and remains uncured for a period of more than forty-five (45) days.

(ii) Failure To Deliver Common Stock . A Delivery Failure (as defined above) occurs and remains uncured for a period of more than twenty (20) days; or at any time, the Company announces or states in writing that it will not honor its obligations to issue shares of Common Stock to Holder upon Exercise by Holder of the Exercise rights of Holder in accordance with the terms of this Warrant.

(iii) Legend Removal Failure . A Legend Removal Failure (as defined above) occurs and remains uncured for a period of twenty (20) days;

(iv) Transfer Delivery Failure . A Transfer Delivery Failure (as defined above) occurs and remains uncured for a period of twenty (20) days;

(v) Corporate Existence; Major Transaction . (A) The Company has failed to (1) place the Successor Major Transaction Consideration into escrow and instruct the escrow agent to release the Successor Major Transaction Consideration to the Holder pursuant to Section 5(b)(iii), or (2) obtain the written agreement of the Successor Entity and cause the Successor Entity to make payment as described in Section 5(b)(iii), (B) the Successor Major Transaction Consideration is not paid contemporaneously with the consummation of the Successor Major Transaction, or (C) with respect to a Major Transaction that is to be treated as an Assumption under the terms hereof, the Company has failed to meet the Assumption requirements of Section 5(b)(i); or

(vi) Section  13 Breach . During the Dividend Restriction Period, the Company declares or pays any dividend or distribution of any kind to the holders of Common Stock of the Company.

(b) Mandatory Early Termination .

(i) Mandatory Early Termination Amount; Cashless Default Exercise . The Company shall notify Holder in writing within two (2) Business Days of the occurrence of an Event of Default. If any Events of Default shall occur then, at the option of Holder, such option exercisable through the delivery of written notice to the Company by such Holder (the “Default Notice”), the Company shall have the right to terminate the outstanding amount of this Warrant and pay to Holder (a “Mandatory Early Termination”), in full satisfaction of its obligations hereunder by delivery of a notice to such effect to Holder within two (2) Business Days following receipt of the Default Notice, an amount payable in cash (the “Mandatory Early Termination Amount” or the “Default Amount”) equal to the Black-Scholes Value of the remaining unexercised portion of this Warrant on the date of such Default Notice (or in the case of an Event of Default referred to in Section 11(a)(vi), on the Trading Day immediately preceding the date the dividend or distribution is declared or, if not first declared, is paid). In the event the Company does not exercise its right to consummate a Mandatory Early Termination, then Holder shall have the right to exercise this Warrant, at any time and from time to time, pursuant to a Cashless Default Exercise in accordance with Section 3(c) above.

21

The Mandatory Early Termination Amount shall be payable within five (5) Business Days following the date of the applicable Default Notice.

(ii) Liquidated Damages . The parties hereto acknowledge and agree that the sums payable as Failure Payments or pursuant to a Mandatory Early Termination shall constitute partial liquidated damages and not penalties. The parties further acknowledge that (i) the amount of loss or damages likely to be incurred by Holder is incapable or is difficult to precisely estimate, (ii) the amounts specified bear a reasonable proportion and are not plainly or grossly disproportionate to the probable loss likely to be incurred by Holder, and (iii) the parties are sophisticated business parties and have been represented by sophisticated and able legal and financial counsel and negotiated this agreement at arm’s length.

Upon the occurrence of an Event of Default, the Default Amount, together with all other amounts payable hereunder, shall immediately become due and payable, all without demand, presentment or notice, all of which hereby are expressly waived, together with all costs, including legal fees and expenses, of collection, and Holder shall be entitled to exercise all other rights and remedies available at law or in equity.

(c) Posting Of Bond . In the event that any Event of Default occurs hereunder, the Company may not raise as a legal defense (in any Lawsuit, as defined below, or otherwise) or justification to such Event of Default any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation of law, unless the Company has posted a surety bond (a “Surety Bond”) for the benefit of such Holder in the amount of 130% of the aggregate Surety Bond Value (as defined below) of all of Holder’s Warrants (the “Bond Amount”), which Surety Bond shall remain in effect until the completion of litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.

For purposes hereof, a “Lawsuit” shall mean any lawsuit, arbitration or other dispute resolution filed by either party herein pertaining to any of this Warrant, the Facility Agreement, the Registration Rights Agreement or any other Loan Document (as defined in the Facility Agreement).

“Surety Bond Value,” for the Warrants shall mean 130% of the of the Black-Scholes Value of the remaining unexercised portion of this Warrant on the Trading Day immediately preceding the date that such bond goes into effect.

(d) Injunction And Posting Of Bond . In the event that the Event of Default referred to in subsection (a) of this Section 11 pertains to the Company’s failure to deliver unlegended shares of Common Stock to Holder pursuant to a Warrant Exercise, legend removal request, or otherwise, the Company may not refuse such unlegended share delivery based on any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation of law, unless an injunction from a court, on prior notice to Holder, restraining and or enjoining Exercise of all or part of said Warrant shall have been sought and obtained by the Company and the Company has posted a Surety Bond for the benefit of such Holder in the amount of the Bond Amount, which Surety Bond shall remain in effect until the completion of litigation of the dispute and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.

22

(e) Remedies, Other Obligations, Breaches And Injunctive Relief . The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant, the Facility Agreement, the Registration Rights Agreement and any other Loan Document, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach (including a breach or threatened breach of Section 13), the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required.

If by the Share Delivery Date, the Borrower shall fail to credit the Lender’s or its designee’s balance account with DTC with the number of Conversion Shares (free of any restrictive legend in the case of a Mandatory Conversion or Forced Conversion or, provided the Unrestricted Condition is satisfied, in the case of a Voluntary Conversion), then, in addition to all other available remedies that the Lender may

A - 8

pursue hereunder and under the Facility Agreement, the Borrower shall pay additional damages to the Lender for each day after the Share Delivery Date such conversion is not timely effected in an amount equal to one and one-half percent (1.5%) of the product of (I) the number of Conversion Shares not issued to the Lender or its designee on or prior to the Share Delivery Date and to which the Lender is entitled and (II) the Volume Weighted Average Price of the Common Stock on the Share Delivery Date. Alternatively in lieu of the foregoing damages, subject to Section 2(c)(iii) , at the written election of the Lender made in the Lender’s sole discretion, if, on or after the applicable Conversion Date, the Lender purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Lender of Conversion Shares that such Lender anticipated receiving from the Borrower (such purchased shares, “ Buy-In Shares ”), the Borrower shall be obligated to promptly pay to the Lender (in addition to all other available remedies that the Lender may otherwise have), 110% of the amount by which (A) the Lender’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares exceeds (B) the net proceeds received by the Lender from the sale of a number of shares equal to up to the number of Conversion Shares such Lender was entitled to receive but had not received on the Share Delivery Date. If the Borrower fails to pay the additional damages set forth in this Section 2(c)(v)(A) within five (5) Business Days of the date incurred, then the Lender entitled to such payments shall have the right at any time, so long as the Borrower continues to fail to make such payments, to require the Borrower, upon written notice, to immediately issue, in lieu of such cash damages, the number of shares of Common Stock equal to the quotient of (X) the aggregate amount of the damages payments described herein divided by (Y) the Conversion Price applicable to the conversion to which the additional damages relate.

(B) Conversion Failure . If for any reason the Lender has not received all of the Conversion Shares it is entitled to prior to the tenth (10th) Business Day after the Share Delivery Date with respect to a conversion of this Note (a “ Conversion Failure ”), then the Lender, upon written notice to the Borrower (a “ Void Conversion Notice ”), may void its conversion (or, in the case of a Mandatory Conversion or a Forced Conversion, the Borrower’s conversion) with respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to the Lender’s Conversion Notice (or, in the case of a Mandatory Conversion or a Forced Conversion, the Borrower’s Mandatory Conversion Notice or Forced Conversion Notice); provided , that the voiding of the Lender’s Conversion Notice (or the Borrower’s Mandatory Conversion Notice or Forced Conversion Notice) shall not affect the Borrower’s obligations to make any payments that have accrued prior to the date of such notice pursuant to Section 2(c)(v)(A) or otherwise. A Conversion Failure shall constitute an Event of Default under the Facility Agreement and entitle the Lenders to all payments and remedies provided under the Facility Agreement upon the occurrence of an Event of Default.

(vi) Book-Entry . Notwithstanding anything to the contrary set forth herein, upon conversion or repayment of this Note in accordance with the terms hereof, the Lender shall not be required to physically surrender this Note to the Borrower unless all of the Principal is being converted or repaid. The Lender and the Borrower shall maintain records showing the Principal converted or repaid and the dates of such conversions or repayments or shall use such other method, reasonably satisfactory to the Lender and the Borrower, so as not to require physical surrender of this Note upon any such partial conversion or repayment. Notwithstanding the foregoing, if this Note is converted or repaid as aforesaid, the Lender

A - 9

may not transfer this Note unless the Lender first physically surrenders this Note to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Lender a new Note of like tenor, registered as the Lender may request, representing in the aggregate the remaining Principal represented by this Note. The Lender and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion or repayment of any portion of this Note, the Principal of this Note may be less than the “Principal Amount” stated on the face hereof.

(vii) Taxes . Without limiting Section 10 , the Borrower shall pay any and all taxes (excluding income taxes, franchise taxes or other taxes levied on gross earnings, profits or the like of the Lender) that may be payable with respect to the issuance and delivery of Conversion Shares upon the conversion of this Note.

(d) Mandatory Conversion .

(i) Subject to the terms and conditions of this Section 2 , including the Mandatory/Forced Conversion Conditions (as defined below) and the limitations set forth in Section 2(f) , in the event that, in any calendar month during the period commencing on April 1, 2019 and ending on June 30, 2020 (the “ Mandatory Conversion Period ”), (A) each of (I) the arithmetic average of the Volume Weighted Average Prices on the five (5) consecutive Trading Days ending on (and including) the fifteenth (15 ^th ) day of such calendar month (or if such day is not a Trading Day, the first Trading Day thereafter) (the “ Mandatory Conversion Measurement Date ”) and (II) the Closing Price on the Mandatory Conversion Measurement Date is greater than the Fixed Conversion Price, and (B) the Initial Mandatory Conversion Trigger shall have occurred in such calendar month (together, the “ Mandatory Conversion Conditions ”), the Borrower shall cause the conversion into Conversion Shares (a “ Mandatory Conversion ”) of the lesser of (X) {INSERT: THE LENDER’S PRO RATA SHARE OF $1,666,666 and (Y) the then outstanding Principal. (ii) In the event that, in any calendar month during the Mandatory Conversion Period, each of (A) the arithmetic average of the Volume Weighted Average Prices on the five (5) consecutive Trading Days ending on (and including the third (3 ^rd ) Trading Day (the “ Initial Mandatory Conversion Measurement Date ”) immediately prior to the Mandatory Conversion Measurement Date in such calendar month and (B) the Closing Price on the Initial Conversion Measurement Date is greater than the Fixed Conversion Price (together, an “ Initial Mandatory Conversion Trigger”), the Borrower shall send a written notice via electronic mail to the Lender (an “ Initial Mandatory Conversion Notice ”) at any time between 8:00 a.m. and 4:00 p.m., New York City time on the first Trading Day following the Initial Mandatory Conversion Measurement Date, certifying that an Initial Mandatory Conversion Trigger has occurred (with reasonable supporting information), stating the Principal amount hereunder to be converted on the Mandatory Conversion Date and stating the number of Conversion Shares to be issued to the Lender (subject to Section 2(d)(iii) and the other terms and conditions of this Section 2(d)). For the avoidance of doubt, (X) simultaneously with delivery of an Initial Mandatory Conversion Notice hereunder, the Borrower shall send an Initial Mandatory Conversion Notice under all other First Out Waterfall Notes. Notwithstanding the delivery of an Initial Mandatory Conversion Notice, a Mandatory Conversion shall not be effected unless all of the Mandatory Conversion

A - 10

Conditions and the other applicable conditions set forth in this Section 2 (including the Borrower’s delivery of a Final Mandatory Conversion Notice) are satisfied.

(iii) By no later than 5:00 p.m., New York City time on the first Trading Day following the date of an Initial Mandatory Conversion Notice, the Lender shall confirm to the Borrower via electronic mail whether the 4.985% Cap (as hereinafter defined) will reduce the number of Shares that may be issued pursuant to such Mandatory Conversion (a “ Mandatory Conversion Lender Notice ”). If the 4.985% Cap will so reduce the number of Shares that may be issued pursuant to the Mandatory Conversion (subject to the terms and conditions of this Section 2(d)) , such notice shall also set forth the maximum number of Conversion Shares that may be issued to the Lender (and the corresponding Principal amount hereunder that may be converted) without exceeding the maximum number of shares that such Lender may receive under the 4.985% Cap (the “ Mandatory Conversion Maximum Share Amount ”), which shall be conclusive and binding upon the Borrower and the Lender. The number of Conversion Shares issuable pursuant to the Mandatory Conversion shall equal the number of Conversion Shares set forth in the Initial Mandatory Conversion Notice; provided , however , that, if the issuance of the number of Conversion Shares set forth in the Initial Mandatory Conversion Notice would violate the 4.985% Cap, the number of Conversion Shares issuable pursuant to the Mandatory Conversion shall instead equal the Mandatory Conversion Maximum Share Amount (and the Principal amount hereunder to be converted on the Mandatory Conversion Date shall be correspondingly reduced).

(iv) In the event that all of the Mandatory Conversion Conditions have been satisfied as of the Mandatory Conversion Measurement Date, the Borrower shall send a written notice via electronic mail to the Lender (a “ Final Mandatory Conversion Notice ”) at any time between 4:00 p.m. and 5:00 p.m., New York City time on the Mandatory Conversion Date certifying that the Mandatory Conversion Conditions and the other applicable conditions set forth in this Section 2 have been satisfied (including reasonable supporting documentation) and specifying the number of Conversion Shares to be issued to the Lender. For the avoidance of doubt, simultaneously with delivery of a Final Mandatory Conversion Notice hereunder, the Borrower shall send a Final Mandatory Conversion Notice under all other Notes.

(v) The Conversion Shares issuable pursuant to a Mandatory Conversion shall be delivered on the Trading Day immediately following the Mandatory Conversion Measurement Date (such Trading Day, the “ Mandatory Conversion Date ”) and in accordance with Section 2(c)(ii) above.

(e) Forced Conversion .

(i) Subject to the terms and conditions of this Section 2 , including the Mandatory/Forced Conversion Conditions (as defined below) and the limitations set forth in Section 2(f) , in the event that the arithmetic average of the Volume Weighted Average Prices on any fifteen (15) consecutive Trading Days commencing on or after the first Trading Day after the Second Amendment Effective Date and ending on or prior to the second Business Day immediately prior to the Maturity Date, is greater than 175% of the Fixed Conversion Price (the “Forced Conversion Condition”), the Borrower may cause the conversion into Conversion Shares (a “ Forced Conversion ”) of the outstanding Principal amount of this Note

A - 11

set forth in the Forced Conversion Notice (as defined below); provided that such Principal amount (A) shall not exceed the result of (I) the Discretionary/Forced Conversion Cap, minus (II) the aggregate Principal of this Note converted into Conversion Shares pursuant to Discretionary Conversions after the Second Amendment Effective Date and prior to the Forced Conversion (the “ Maximum Forced Conversion Amount ”), and (B) shall not be less than the least of (1) the Maximum Forced Conversion Amount, (2) the then outstanding Principal, and (3) $1,000,000. The Borrower shall effect Forced Conversions under each of the First Out Waterfall Notes on a pro rata basis, based upon the respective outstanding Principal amounts thereof.

(ii) To effect a Forced Conversion, the Borrower shall send a written notice via electronic mail to the Lender (a “ Forced Conversion Notice ”) at any time between 4:00 p.m. and 5:00 p.m., New York City time on the Trading Day on which the Forced Conversion Condition is satisfied. The Forced Conversion Notice shall certify that the Forced Conversion Condition and the other applicable conditions set forth in this Section 2 have satisfied (including reasonable supporting information), shall state the Principal amount hereunder that the Borrower shall cause to be converted on the Forced Conversion Date and shall state the number of Conversion Shares to be issued to the Lender (subject to Section 2(e)(iii) and the other terms and conditions of this Section 2(e)). Simultaneously with delivery of a Forced Conversion Notice hereunder, the Borrower shall send a Forced Conversion Notice with respect to a pro rata portion of the Principal of each other First Out Waterfall Notes. Notwithstanding the foregoing, in no event shall the Borrower send any Forced Conversion Notice to the Lender within fourteen (14) days of any other Forced Conversion Notice sent by the Borrower to the Lender.

(iii) By no later than 5:00 p.m., New York City time on the first Trading Day following the date of the Forced Conversion Notice, the Lender shall confirm to Borrower via electronic mail whether the 4.985% Cap (as defined below) will reduce the number of Shares that may be issued pursuant to such Forced Conversion (the “ Forced Conversion Lender Notice ”). If the 4.985% Cap will so reduce the number of Shares that may be issued pursuant to the Forced Conversion (subject to the terms and conditions of this Section 2(d) ), the Forced Conversion Lender Notice shall also set forth the maximum number of Conversion Shares that may be issued to the Lender (and the corresponding Principal amount hereunder that may be converted) without exceeding the maximum number of shares that such Lender may receive under the 4.985% Cap (the “ Forced Conversion Maximum Share Amount ”). The number of Conversion Shares issuable pursuant to the Forced Conversion shall equal the number of Conversion Shares set forth in the Forced Conversion Notice; provided , however , that, if the issuance of the number of Conversion Shares set forth in the Forced Conversion Notice would violate the 4.985% Cap, the number of Conversion Shares issuable pursuant to the Forced Conversion shall instead equal the Forced Conversion Maximum Share Amount (and the Principal amount hereunder to be converted on the applicable Conversion Date shall be correspondingly reduced).

(iv) The Conversion Shares issuable pursuant to a Forced Conversion shall be delivered within the timeframe and in accordance with Section 2(c)(ii) above.

(f) Limitations on Conversions .

A - 12

Notwithstanding anything herein to the contrary, the Borrower shall not issue to the Lender, and the Lender may not acquire, a number of shares of Common Stock upon any conversion of this Note (whether a Voluntary Conversion, a Mandatory Conversion or a Forced Conversion) or otherwise issue any shares of Common Stock pursuant hereto or the Facility Agreement to the extent that, upon such conversion, the number of shares of Common Stock then beneficially owned by the Lender and its Affiliates and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Lender’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group” of which the Lender is a member, but excluding shares beneficially owned by virtue of the ownership of the Warrants or other securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein) would exceed 4.985% of the total number of shares of common stock then issued and outstanding (the “ 4.985% Cap ”); provided , however , that the 4.985% Cap shall only apply to the extent that the Common Stock is deemed to constitute an “equity security” pursuant to Rule 13d-1(i) promulgated under the Exchange Act. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the SEC, and the percentage held by the Lender shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. Upon the written request of the Lender, the Borrower shall, within two (2) Trading Days, confirm orally and in writing to the Lender the number of shares of Common Stock then outstanding. Without limiting the foregoing, in no event shall the number of shares issued to the Lender pursuant to a Mandatory Conversion exceed the Lender’s Mandatory Conversion Maximum Share Amount (if any), as applicable to such Mandatory Conversion, and in no event shall the number of shares issued to the Lender pursuant to a Forced Conversion exceed the Lender’s Forced Conversion Maximum Share Amount (if any), as applicable to the Forced Conversion

(ii) Elective Conversion Issuance Limit . Notwithstanding anything to the contrary contained herein, this Note shall not be convertible pursuant to an Elective Conversion, and the Borrower shall not issue Conversion Shares upon any Elective Conversion of this Note, to the extent that the issuance of shares of Common Stock upon such Elective Conversion, together with any issuances of shares of Common Stock under this Note pursuant to Elective Conversions after the Second Amendment Effective Date and prior to such Elective Conversion, would exceed the Elective Conversion Issuance Limit ( provided , for the avoidance of doubt, that upon any Elective Conversion of this Note, the Borrower shall convert the maximum portion of Principal set forth in the applicable Conversion Notice that may be converted into shares of Common Stock without so exceeding the Elective Conversion Issuance Limit, subject to the 4.985% Cap). For the avoidance of doubt, the limitation set forth in this Section 2(f)(ii) shall not apply to any Discretionary Conversion, Mandatory Conversion or Forced Conversion.

(iii) Discretionary/Forced Conversion Issuance Cap . Notwithstanding anything to the contrary contained herein, this Note shall not be convertible pursuant to a Discretionary Conversion or a Forced Conversion, and the Borrower shall not issue Conversion Shares upon any Discretionary Conversion or Forced Conversion of this Note, to the extent that the aggregate Principal of this Note that would otherwise be converted pursuant to the applicable Discretionary Notice or Forced Conversion Notice, together with the aggregate Principal of this Note converted into Conversion Shares after the Second

A - 13

Amendment Effective Date and prior to such Discretionary Conversion or Forced Conversion, would exceed the Discretionary/Forced Conversion Cap ( provided , for the avoidance of doubt, that upon any Discretionary Conversion of this Note, the Borrower shall convert the maximum portion of Principal set forth in the applicable Conversion Notice that may be converted into shares of Common Stock without so exceeding the Discretionary/Forced Conversion Cap, subject to the 4.985% Cap). For the avoidance of doubt, the limitation set forth in this Section 2(f)(iii) shall not apply to any Elective Conversion or Mandatory Conversion.

(iv) Other Applicable Restrictions on Conversion of the Note . Notwithstanding anything to the contrary contained herein, the Borrower shall not deliver a Mandatory Conversion Notice or a Forced Conversion Notice, and the Borrower shall not effect a Mandatory Conversion or a Forced Conversion, (A) during the occurrence of a Delisting Event, (b) at any time following such time as the Borrower has delivered (or is obligated to deliver) a Major Transaction Notice in respect of a Major Transaction, (c) at any time following the occurrence, and during the continuance, of an Event of Default or a Default, (d) from and after a Withholding Date, (e) unless all material information regarding the Borrower (including any material information that may be included in, or reflected by, the Mandatory Conversion Notice or Forced Conversion Notice, but excluding any material information relating to the Borrower’s operating results for the fiscal quarter in which the Mandatory Conversion Notice or Forced Conversion Notice is delivered other than operating results that would trigger non-compliance with a covenant under the Facility Agreement or the ABL Credit Facility) has been publicly disclosed in a report filed pursuant to the Exchange Act or has been otherwise publicly disclosed in a manner calculated to reach the securities marketplace through one of the Borrower’s recognized channels of distribution, (h) unless all shares of Common Stock issuable pursuant to the Mandatory Conversion or Forced Conversion will constitute Freely Tradeable Shares, (i) unless the Borrower is in compliance with the “current public information” requirement of Rule 144(c) under the Securities Act, (j) if the transfer agent for the Common Stock is not participating in DTC’s Fast Automated Securities Transfer Program, or (k) if any Lender, after consultation with counsel of its choosing, advises the Borrower that the receipt or resale of Common Stock issued or issuable hereunder would result in such Lender being deemed an “underwriter” within the meaning of Section 2(11) under the Securities Act (collectively, the “ Mandatory/Forced Conversion Conditions ”), except to the extent the Lender has waived any such Mandatory/Forced Conversion Condition by written notice to the Borrower. If any of the Mandatory/Forced Conversion Conditions is not satisfied at any time following the delivery of a Mandatory Conversion Notice or Forced Conversion Notice and prior to the Share Issuance Date in respect of the Mandatory Conversion or Forced Conversion (as applicable), the Borrower shall immediately notify the Lender of such failure and, unless the Lender waives such Mandatory/Forced Conversion Condition by written notice to the Borrower, the Mandatory Conversion Notice or Forced Conversion Notice (as applicable) shall be voided and the Mandatory Conversion or Forced Conversion (as applicable) shall not be effected.

The Company covenants and agrees that, upon any conversion of this Note, all shares of Common Stock issued upon such conversion shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive rights, rights of first refusal or similar rights of any Person.

4. Voting Rights .

Section 2.03. Date and Denomination of Notes; Payments of Interest and Defaulted Amounts . (a) The Notes shall be issuable only in registered form without coupons and only in

13

minimum denominations of $1.00 principal amount and integral multiples in excess thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date specified on the face of such Note. Accrued interest on the Notes shall be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.

(b) The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date (the “ Interest Amount ”).

The Company shall, at the Company’s option, either (i) pay the Interest Amount in cash, (ii) issue shares of Common Stock in satisfaction of such Interest Amount in accordance with the terms hereof, or (iii) pay PIK Interest as set forth in Section 2.11. Interest shall accrue from April 3, 2019, or from the most recent date to which interest had been paid or provided for to, but excluding the next scheduled Interest Payment Date until April 3, 2024.

If the Company elects to pay the Interest Amount in cash, such amount and any principal amounts of any Note (x) in the case of any Physical Note, shall be payable at the office or agency of the Company maintained by the Company for such purposes in the contiguous United States, which shall initially be the Corporate Trust Office and (y) in the case of any Global Note, shall be payable by wire transfer of immediately available funds to the account of the Depositary or its nominee. The Company shall pay interest, if paid in cash (i) on any Physical Notes (A) to Holders holding Physical Notes having an aggregate principal amount of $2,000,000 or less, by check mailed to the Holders of these Notes at their address as it appears in the Note Register and (B) to Holders holding Physical Notes having an aggregate principal amount of more than $2,000,000 either by check mailed to each Holder or, upon application by such a Holder to the Note Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Note Registrar to the contrary or (ii) on any Global Note by wire transfer of immediately available funds to the account of the Depositary or its nominee.

If the Company elects to pay the Interest Amount in shares of Common Stock, the number of such shares to be issued shall be the number determined by dividing (x) the Interest Amount due or to be converted (as applicable), by (y) the Last Reported Sale Price as of the date on which the Interest Amount was calculated. Such shares shall be issued and delivered on the applicable Interest Payment Date. In order to pay the Interest Amount in shares of Common Stock, the Company shall deliver a notice (an “ Interest Payment Notice ”) to the Trustee no later than the 15th calendar day immediately prior to the Regular Record Date preceding such Interest Payment Date, which notice shall state the total Interest Amount to be paid on the Interest Payment Date and the number of shares of Common Stock to be issued in satisfaction thereof. The Trustee, on behalf of the Company, shall promptly upon receipt of the Interest Payment Notice, and in no event later than the 10th calendar day immediately prior to the Regular Record Date preceding such Interest Payment Date, deliver a corresponding notice prepared by the Company (which may be the same as the Interest Payment Notice) to the Holders.

14

(c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest per annum at the then-applicable rate borne by the Notes plus one percent, subject to the enforceability thereof under applicable law, from, and including, such relevant payment date, and such Defaulted Amounts together with such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall agree to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date at least five (5) Business Days before such notice is to be sent to the Holders, and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Amounts and the special record date therefor to be sent to each Holder not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so sent, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(c).

(ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.04. Execution, Authentication and Delivery of Notes . The Notes shall initially be delivered in definitive, registered form to the Holders and shall be signed in the name and on behalf of the Company by the manual or facsimile signature by one of its Chief Executive Officer, President, Chief Financial Officer, Treasurer, Secretary or any of its Executive or Senior Vice Presidents.

15

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes (including PIK Notes issued in physical form) executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall manually authenticate and deliver such Notes, without any further action by the Company hereunder; provided that the Trustee shall be entitled to receive an Officers’ Certificate and Opinion of Counsel of the Company with respect to the issuance, authentication and delivery of such Notes.

Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the Form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such person was not such an Officer.

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary . (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “ Note Register ”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes. Such register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby initially appointed the “ Note Registrar ” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may change or appoint one or more co-Note Registrars in accordance with Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall, upon receipt of a

16

Company Order, authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Note Registrar or any co-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or any co-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion, or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fourth paragraph from the end of Section 2.05(c), all Notes shall be represented by one or more Notes in global form (each, a “ Global Note ”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

(c) Notwithstanding any other provisions of this Indenture, a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for exchange of a Global Note or a portion thereof for one or more Physical Notes in accordance with the second immediately succeeding paragraph.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company to act as Depositary with respect to any Global Notes. Initially, each Global Note, if any, shall be issued to the Depositary,

17

registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co.

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed by the Company within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding to such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

Physical Notes issued in exchange for all or a part of the Global Note, pursuant to this Section 2.05(c), shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) of the immediately preceding paragraph, the relevant beneficial owner, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

At such time as all interests in a Global Note have been converted, canceled, repurchased, redeemed or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased, redeemed or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

None of the Company, the Trustee, the Paying Agent, the Conversion Agent or any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Members of, or participants in, the Depositary shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any

18

written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(d) RESERVED.

(e) Any Note or Common Stock issued upon the conversion or exchange of a Note that is repurchased or owned by any Affiliate of the Company (or any Person who was an Affiliate of the Company at any time during the three months immediately preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless the resale is registered under the Securities Act or conducted pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Common Stock, as the case may be, no longer being a “restricted security” (as defined under Rule 144). The Company shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.08.

(f) Notwithstanding anything contained herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible for ascertaining whether any transfer complies with the registration provisions of or exemptions from the Securities Act, applicable state securities laws or other applicable federal or state laws.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes . In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon receipt of a Company Order the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of a Company Order and such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, any co-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the

19

Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, conversion or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07. Temporary Notes . Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent upon receipt of a Company Order shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08. Cancellation of Notes Paid, Converted, Etc . The Company shall cause all Notes surrendered for the purpose of payment, repurchase, registration of transfer or exchange or conversion, if surrendered to any Person other than the Trustee (including any of the Company’s agents, Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it upon receipt of a Company Order, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of cancelled Notes in accordance with its customary procedures. The Trustee shall deliver copies of such cancelled Notes to the Company, at the Company’s written request in a Company Order.

20

Section 2.09. CUSIP Numbers . The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 2.10. Additional Notes; Repurchases . The Company may, without the consent of the Holders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (other than differences in the issue date, the issue price and interest accrued prior to the issue date of such additional Notes) in an unlimited aggregate principal amount; provided that such additional Notes shall not reduce the amount of Exchange Notes subject to Mandatory Conversion in Section 14.02. If any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the Trustee shall reasonably request. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08, and upon receipt of a Company Order, the Trustee and no one else shall cancel all Notes so surrendered and such Notes shall no longer be considered outstanding under this Indenture upon their surrender to the Trustee.

Section 2.11. Issuance of PIK Notes; Payment of PIK Interest . If the Company determines to pay PIK Interest in respect of the Notes, subject to any restrictions as set forth in the Form of Note in Exhibit A to this Indenture, the Company may elect to either increase the outstanding principal amount of the Notes or issue additional Notes (the “ PIK Notes ”) under this Indenture having the same terms as the Notes (in each case, a “ PIK Payment ”). The Company shall make a PIK Payment (x) with respect to Notes represented by one or more Global Notes, by increasing the principal amount of the outstanding Global Notes by an amount equal to the amount of PIK Interest due and payable (rounded up to the nearest whole U.S. dollar) and (y) with respect to Notes represented by Physical Notes, by issuing PIK Notes in physical form in an amount equal to the amount of PIK Interest due and payable (rounded up to the nearest whole U.S. dollar). In order to pay PIK Interest pursuant to this Section 2.11, the Company shall deliver a notice (a “ PIK Notice ”) to the Trustee no later than the 15th calendar day immediately prior to the Regular Record Date preceding such Interest Payment Date, which notice shall state the total amount of interest to be paid on the Interest Payment Date and the amount of such interest to be paid as PIK Interest in accordance with the terms of the Notes. The Trustee, on behalf of the Company, shall promptly upon receipt of the PIK Notice, and in no event later than the 10th calendar day immediately prior to the Regular Record Date preceding such Interest Payment

21

Date, deliver a corresponding notice prepared by the Company (which may be the same as the PIK Notice) to the Holders.

(b) Any PIK Notes issued in physical form will be issued with the designation “PIK Notes” on the face of such PIK Notes, and shall be in minimum denominations of $1.00 and integral multiples thereof. Any PIK Notes ranking pari passu with the Notes may be created and issued from time to time by the Company without notice to or consent of the Holders and shall be consolidated with and form a single class with the Notes and shall have the same terms as to status or otherwise as the Notes. All PIK Notes issued pursuant to a PIK Payment shall mature on the same Maturity Date as the originally issued Notes and shall be governed by, and subject to the terms, provisions and conditions of, this Indenture and shall have the same rights and benefits as the Notes. Trustee shall authenticate and deliver such PIK Notes in physical form for original issuance to the Holders thereof on the relevant Record Date, as shown by the records of the Note Register of such Holders.

(c) Following an increase in the principal amount of the outstanding Global Notes as a result of a PIK Payment, the Global Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in physical form will be distributed to Holders, dated as of the applicable Interest Payment Date and will bear interest on the principal amount of such PIK Note from and after the Interest Payment Date in respect of which such PIK Payment was made.

This Indenture and the Notes shall upon request of the Company contained in an Officers’ Certificate cease to be of further effect, and the Trustee, at the expense of the Company, shall execute such instruments reasonably requested by the Company, acknowledging satisfaction and discharge of this Indenture and the Notes, when (i) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced, paid or converted as provided in Section 2.06) have been delivered to the Trustee for cancellation; or (ii) the Company has deposited with the Trustee or delivered to Holders, as applicable, after the Notes have become due and payable, whether on the Maturity Date, any Fundamental Change Repurchase Date, upon conversion or otherwise, cash or cash, shares of Common Stock or a combination thereof, as applicable, solely to satisfy the Company’s Conversion Obligation, sufficient to pay all of the outstanding Notes and all other sums due and payable under this Indenture by the Company; and the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture and the Notes have been complied with.

P ARTICULAR C OVENANTS OF THE C OMPANY

Section 4.01. Payment of Principal and Interest . The Company covenants and agrees that it will cause to be paid the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, each of the Notes at the places, at the respective times and in the manner provided herein and in the Notes. PIK Interest shall be considered paid on the Interest Payment Date after any PIK Notice has been delivered to Holders. In respect of such Interest Payment Date and PIK Payment, the Trustee shall either receive (i) a Company Order, pursuant to Section 2.11, to increase the balance of any Global Note to reflect such PIK Interest or (ii) a PIK Note duly executed by the Company together with a Company Order, pursuant to Section 2.11, requesting the authentication of such PIK Note by the Trustee.

Section 4.02. Maintenance of Office or Agency . The Company will maintain in the contiguous United States an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase (“ Paying Agent ”) or for conversion (“ Conversion Agent ”). The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made or served at the Corporate Trust Office.

The Company may also from time to time designate as co-Note Registrars one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the contiguous United States for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The terms “ Paying Agent ” and “ Conversion Agent ” include any such additional or other offices or agencies, as applicable.

The Company hereby initially designates the Trustee as the Paying Agent, Note Registrar, Custodian and Conversion Agent and the Corporate Trust Office as the office or agency in the contiguous United States, where Notes may be surrendered for registration of transfer or exchange or for presentation for payment or repurchase or for conversion. The Corporate Trust Office shall not be a place for service of legal process on the Company.

Section 4.03. Appointments to Fill Vacancies in Trustee ’ s Office . The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.09, a Trustee, so that there shall at all times be a Trustee hereunder.

Section 4.04. Provisions as to Paying Agent . (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04:

(i) that it will hold all sums held by it as such agent for the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and

23

accrued and unpaid interest on, the Notes in trust for the benefit of the Holders of the Notes;

(ii) that it will give the Trustee prompt notice of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes when the same shall be due and payable; and

(iii) that at any time during the continuance of an Event of Default, upon request of the Trustee, it will forthwith pay to the Trustee all sums so held in trust.

The Company shall, on or before each due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes, deposit with the Paying Agent a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) or accrued and unpaid interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of any failure to take such action; provided that if such deposit is made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York City time, on such date.

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Fundamental Change Repurchase Price, if applicable) and accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, the Notes when the same shall become due and payable.

Upon the occurrence of any Event of Default under Section 6.01(j) or Section 6.01(k), the Trustee shall automatically be the Paying Agent.

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

24

(if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease.

Section 4.05. Existence . Subject to Article 11, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of any Significant Subsidiary.

The Company shall take such further action as any Holder or beneficial owner of such Notes or such Common Stock may reasonably request to the extent from time to time required to enable such Holder or beneficial owner to sell such Notes or shares of Common Stock in accordance with Rule 144A, as such rule may be amended from time to time.

Any such document or report that the Company files with the Commission via the Commission’s EDGAR system shall be deemed to be filed with the Trustee for purposes of this Section 4.06(b) at the time such documents are filed via the EDGAR system; provided, that the Trustee shall have no obligation to monitor whether such filings have been made or the content thereof.

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

(d) If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file any document or report that it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (as a result of restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes), the Company shall pay Additional Interest on the Notes. Such Additional Interest shall accrue on the Notes at the rate of 0.50% per annum of the principal amount of the Notes outstanding for each day during such period for which the Company’s failure to file has occurred and is

25

continuing or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding).

(e) If, and for so long as, the restrictive legend on the Notes specified in Section 2.05(c) has not been removed, the Notes are assigned a restricted CUSIP or the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates or Holders that were the Company’s Affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes) as of the 365th day after the last date of original issuance of the Notes, the Company shall pay Additional Interest on the Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the restrictive legend on the Notes has been removed in accordance with Section 2.05(c), the Notes are assigned an unrestricted CUSIP and the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (or Holders that were the Company’s Affiliates at any time during the three months immediately preceding) without restrictions pursuant to U.S. securities laws or the terms of this Indenture or the Notes.

(f) Additional Interest will be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes.

(g) The Additional Interest that is payable in accordance with Section 4.06(d) or Section 4.06(e) shall be in addition to, and not in lieu of, any Additional Interest that may be payable as a result of the Company’s election pursuant to Section 6.03.

(h) If Additional Interest is payable by the Company pursuant to Section 4.06(d) or Section 4.06(e), the Company shall deliver to the Trustee an Officers’ Certificate to that effect stating (i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable.

Section 4.07. Stay, Extension and Usury Laws . The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law that would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or that may affect the covenants or the performance of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 4.08. Compliance Certificate; Statements as to Defaults . The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending on December 31, 2019) an Officers’ Certificate stating

(l) the occurrence of an Event of Default as such term is defined and as set forth in the Voluntary Indenture.

Section 6.02. Acceleration; Rescission and Annulment . If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(j) or Section 6.01(k) with respect to the Company or any of its Significant Subsidiaries), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(j) or Section 6.01(k) with respect to the Company or any of its Significant Subsidiaries occurs, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable without any declaration or other act of the Holders or any act on the part of the Trustee.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest to the extent that payment of such interest is enforceable under applicable law, and on such principal at the rate borne by the Notes at such time, plus one percent) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due

29

solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding (including PIK Notes), by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver, as the case may be, the consideration due upon conversion of the Notes.

Section 6.03. Additional Interest . Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.06(b) shall after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to 0.25% per annum of the principal amount of the Notes outstanding for each day during the 60-day period on which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs. Additional Interest payable pursuant to this Section 6.03 shall be in addition to, not in lieu of, any Additional Interest payable pursuant to Section 4.06(d) or Section 4.06(e). If the Company so elects, such Additional Interest shall be payable in the same manner and on the same dates as the stated interest payable on the Notes. On the 61st day after such Event of Default (if the Event of Default relating to the Company’s failure to file is not cured or waived prior to such 61st day), the Notes shall be immediately subject to acceleration as provided in Section 6.02. The provisions of this paragraph will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default other than the Company’s failure to comply with its obligations as set forth in Section 4.06(b). In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment but does not pay the Additional Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

In order to elect to pay Additional Interest as the sole remedy during the first 60 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify all Holders of the Notes, the Trustee and the Paying Agent in writing of such election prior to the beginning of such 60-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

Section 6.04. Payments of Notes on Default; Suit Therefor . If an Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, plus one percent, and, in addition thereto, such further amount as shall be sufficient to cover any amounts

30

due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company or such other obligor, the property of the Company or such other obligor, or in the event of any other judicial proceedings relative to the Company or such other obligor upon the Notes, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

31

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

Any monies or property collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

Second , in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of interest on, and any cash due upon conversion of, the Notes in default in the order of the date due of the payments of such interest and cash due upon conversion, as the case may be, with interest (to the extent that such interest has been collected by the Trustee) upon such overdue payments at the rate borne by the Notes at such time, plus one percent, such payments to be made ratably to the Persons entitled thereto;

Third , in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid to the payment of the whole amount (including, if applicable, the payment of the Fundamental Change Repurchase Price and any cash due upon conversion) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and, to the extent that such interest has been collected by the Trustee, upon overdue installments of interest at the rate borne by the Notes at such time plus one percent, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Fundamental Change Repurchase Price and the cash due upon conversion) and interest without preference or priority of principal over interest, or of interest over principal or of any installment of interest over any other installment of interest, or of any Note over any other Note, ratably to the

32

aggregate of such principal (including, if applicable, the Fundamental Change Repurchase Price and any cash due upon conversion) and accrued and unpaid interest; and

Fourth , to the payment of the remainder, if any, to the Company.

Section 6.06. Proceedings by Holders . Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

(c) such Holder(s) shall have offered to the Trustee such security or indemnity satisfactory to it in its reasonable discretion against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee for 60 days after its receipt of such notice, request and offer of such security or indemnity, shall have failed to institute any such action, suit or proceeding; and

(e) no direction that is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09,

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, each Holder shall have the right, which is absolute and unconditional, to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or

33

delivery, as the case may be, and such rights shall not be impaired without the consent of such Holders.

Section 6.07. Proceedings by Trustee . In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 6.08. Remedies Cumulative and Continuing . Except as provided in the last paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such directions are unduly prejudicial to such Holder) or that would involve the Trustee in personal liability, unless the Trustee is offered indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction; provided , however , that the Trustee may take any other action deemed necessary by the Trustee that is not inconsistent with such direction.

Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights

34

hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Section 6.10. Notice of Defaults . The Trustee shall, within 90 days after it obtains knowledge of the occurrence and continuance of a Default of which a Responsible Officer has actual knowledge, deliver to all Holders notice of all Defaults known to a Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such notice; provided that, except in the case of a Default in the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable), or accrued and unpaid interest on, any of the Notes or a Default in the payment or delivery of the consideration due upon conversion, the Trustee shall be protected in withholding such notice if and so long as a Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders.

Section 6.11. Undertaking to Pay Costs . All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Fundamental Change Repurchase Price, if applicable) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note, or receive the consideration due upon conversion, in accordance with the provisions of Article 14.

The Trustee’s right to receive

(d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10.

Section 7.10. Acceptance by Successor Trustee . Any successor trustee appointed as provided in Section 7.09 shall execute, acknowledge and deliver to the Company and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 7.06, execute and deliver an instrument transferring to such successor trustee all the rights and powers of the trustee so ceasing to act. Upon request of any such successor trustee, the Company shall execute any and all instruments in writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers.

41

Any trustee ceasing to act shall, nevertheless, retain a senior claim to which the Notes are hereby made subordinate on all money or property held or collected by such trustee as such, except for funds held in trust for the benefit of Holders of particular Notes, to secure any amounts then due it pursuant to the provisions of Section 7.06.

No successor trustee shall accept appointment as provided in this Section 7.10 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 7.08.

Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, each of the Company and the successor trustee, at the written direction and at the expense of the Company shall deliver or cause to be delivered notice of the succession of such trustee hereunder to the Holders.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee or authenticating agent appointed by such predecessor trustee, and deliver such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee or an authenticating agent appointed by such successor trustee may authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of the successor trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have; provided , however , that the right to adopt the certificate of authentication of any predecessor trustee or to authenticate Notes in the name of any predecessor trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 7.12. Trustee ’ s Application for Instructions from the Company . Any application by the Trustee for written instructions from the Company (other than with regard to any action proposed to be taken or omitted to be taken by the Trustee that affects the rights of the Holders of the Notes under this Indenture) may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective.

C ONVERSION OF N OTES

Section 14.01. Voluntary Conversion . (a) Subject to and upon compliance with the provisions of this Article 14, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion of such Note (i) subject to satisfaction of the conditions described in Section 14.01(b), at any time prior to the close of business on the Business Day immediately preceding January 1, 2024 under the circumstances and during the periods set forth in Section 14.01(b), and (ii) regardless of the conditions described in Section 14.01(b), on or after January 1, 2024 and prior to the close of business on the Business Day immediately preceding the Maturity Date, in each case, at an initial conversion rate of 0.12103 (subject to adjustment as provided in this Article 14, the “ Applicable Conversion Rate ”) per $1.00 principal amount of Notes (subject to, and in accordance with, the settlement provisions of Section 14.03, the “ Conversion Obligation ”), equivalent to the Conversion Price.

(b) (i) Prior to the close of business on the Business Day immediately preceding January 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at any time during the five consecutive Business Day period immediately following any twenty consecutive Trading Day period (the “ Measurement Period ”) in which the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder of Notes in accordance with this subsection (b)(i), for each Trading Day of the Measurement Period was less than 98% of the product of the Last Reported Sale Price of the Common Stock on each such Trading Day and the Applicable Conversion Rate on each such Trading Day (the “ Trading Price Condition ”). The Trading Prices shall be determined by the Bid Solicitation Agent pursuant to this subsection (b)(i) and the definition of Trading Price set forth in this Indenture. The Company shall provide written notice to the Bid Solicitation Agent (if other than the Company) of the three

51

independent nationally recognized securities dealers selected by the Company pursuant to the definition of Trading Price, along with appropriate contact information for each. The Bid Solicitation Agent shall have no obligation to determine the Trading Price per $1,000 principal amount of Notes unless the Company has requested such determination in writing (and provided the Bid Solicitation Agent of the names and contact information for such dealers) and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Notes on any Trading Day would be less than 98% of the product of the Last Reported Sale Price of the Common Stock on such Trading Day and the Applicable Conversion Rate on such Trading Day, at which time the Company shall instruct the Bid Solicitation Agent in writing to determine the Trading Price per $1,000 principal amount of Notes beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of Notes is greater than or equal to 98% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate.

If the Company does not instruct the Bid Solicitation Agent to determine the Trading Price per $1,000 principal amount of Notes when obligated as provided in the preceding sentence, or if the Company instructs the Bid Solicitation Agent in writing to obtain bids and the Bid Solicitation Agent fails to make such determination, then, in either case, the Trading Price per $1,000 principal amount of Notes shall be deemed to be less than 98% of the product of the Last Reported Sale Price of the Common Stock and the Applicable Conversion Rate on each Trading Day of such failure.

If on any date of determination of the Trading Price (i) the Bid Solicitation Agent cannot reasonably obtain at least one bid for $2,000,000 principal amount of Notes from an independent nationally recognized securities dealer, (ii) if the Company has failed to request the Bid Solicitation Agent to obtain bids when required or (iii) if the Company requested the Bid Solicitation Agent to obtain bids and the Bid Solicitation Agent has failed to obtain such bids, then, in each case, the Notes shall be convertible under the Trading Price Condition for the next 5 consecutive Business Days following such date of determination. The Company shall determine the Trading Price of the Notes and whether the Trading Price Condition has been met, and, if so, the Company shall so notify the Holders, the Trustee, the Conversion Agent and the Bid Solicitation Agent.

If, at any time after the Trading Price Condition has been met, the Trading Price per $1,000 principal amount of the Notes is greater than or equal to 98% of the product of the Closing Sale Price of the Common Stock and the applicable Applicable Conversion Rate for such date, the Company shall so notify the Holders, the Trustee, the Conversion Agent and the Bid Solicitation Agent.

If the Trading Price condition set forth above has been met, the Company shall so notify the Holders in writing, the Trustee and the Conversion Agent (if other than the Trustee).

52

Rate for such date, the Company shall so notify the Holders of the Notes in writing, the Trustee and the Conversion Agent (if other than the Trustee).

(ii) If, prior to the close of business on the Business Day immediately preceding January 1, 2024, the Company elects to:

(A) issue to all or substantially all holders of the Common Stock any rights, options or warrants (other than pursuant to a stockholder rights plan in respect of which the stockholder rights have not separated from the shares of Common Stock) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance; or

(B) distribute cash, debt securities (or other evidence of indebtedness) or other assets or securities (including, for the avoidance of doubt, any rights, options or warrants that are not described in clause (i) above, but excluding dividends or distributions described in Section 14.04(c), which distribution has a per share value exceeding 10% of the Closing Sale Price of Common Stock as of the Trading Day immediately preceding the declaration date for such distribution,

then, in either case, the Company shall notify in writing all Holders of the Notes, the Trustee and the Conversion Agent (if other than the Trustee) either (x) at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution or (y) at least 10 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution; provided that, if the Company provides such notice in accordance with this clause (y) but not in accordance with the immediately preceding clause (x), notwithstanding anything to the contrary in Section 14.02 or any other provision of this Indenture, the Company shall be required to settle all conversions of Notes with a Conversion Date occurring during the period from, and including, the date of such notice to, and including, the Ex-Dividend Date for such distribution using Physical Settlement and the Company shall so notify the Holders in such notice. Once the Company has given such notice, Holders may surrender their Notes for conversion at any time until the earlier of the close of business on the Business Day immediately preceding the Ex-Dividend Date and the Company’s announcement that such issuance or distribution will not take place. A Holder may not convert any of its Notes under this subsection (b)(ii) if the Company provides that Holders of the Notes shall participate, at the same time and upon the same terms as holders of Common Stock and as a result of holding the Notes, in the relevant distribution described above without having to convert their Notes as if they held a number of shares of Common Stock equal to the Applicable Conversion Rate on the record date for the distribution multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(iii) If (A) a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the close of business on the Business

53

Day immediately preceding January 1, 2024, regardless of whether a Holder has the right to require the Company to repurchase the Notes pursuant to Section 15.02, or (B) the Company is a party to a consolidation, merger, binding share exchange, or sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of its assets that occurs prior to the close of business on the Business Day immediately preceding January 1, 2024, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets, then all or any portion of a Holder’s Notes may be surrendered for conversion at any time from or after the date that is 35 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the earlier of (x) the Business Day after the Company gives notice of such transaction and (y) the actual effective date of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the close of business on the related Fundamental Change Repurchase Date. The Company shall give notice to Holders, the Trustee and the Conversion Agent (if other than the Trustee) (x) as promptly as practicable following the date the Company publicly announces such transaction but in no event less than 35 Scheduled Trading Days prior to the anticipated effective date of such transaction or (y) if the Company does not have knowledge of such transaction at least 35 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company receives notice, or otherwise becomes aware, of such transaction, but in no event later than the actual effective date of such transaction; provided that, notwithstanding the foregoing, in no event shall the Company be required to provide such notice to the Holders before the earlier of such time as the Company or its affiliates (x) have publicly disclosed or acknowledged the circumstances giving rise to such transaction or event and (y) are required to publicly disclose under applicable law or the rules of any securities exchange on which the Common Stock is then listed or admitted for trading the circumstances giving rise to such transaction or event.

(iv) Notwithstanding anything to the contrary in this Section 14.01, prior to the close of business on the Business Day immediately preceding January 1, 2024, a Holder may surrender all or any portion of its Notes for conversion at the Applicable Conversion Rate, at any time during any calendar quarter commencing after the calendar quarter ending on June 30, 2019 (and only during such calendar quarter), if the Last Reported Sale Price of the Common Stock for at least 20 Trading Days (whether or not consecutive) during the period of 30 consecutive Trading Days ending on, and including, the last Trading Day of the immediately preceding calendar quarter is greater than or equal to 110% of the Conversion Price on each applicable Trading Day. Provided that no Mandatory Conversions pursuant to Section 14.02 are occurring during a particular calendar quarter, the Company shall determine at the end of the immediately preceding calendar quarter whether the Notes may be surrendered for conversion in accordance with this clause Section 14.01(b)(iv) and shall notify the Holders, the Conversion Agent and the Trustee if the Notes become convertible in accordance with this clause (iv).

(iii) at or prior to the settlement date of the Mandatory Conversion, for any Exchange Notes validly surrendered for conversion prior to the Mandatory Conversion Date in accordance with the terms of this Indenture, the Company shall have delivered and paid the number of shares of Common Stock and the amount of cash due upon conversion of the Exchange Notes to the Holders of such Exchange Notes in accordance with Section 14.02;

(iv) shares of Common Stock to be issued upon conversion may be issued in full without violating the rules or regulations of The New York Stock Exchange or any other applicable Eligible Market on which the Common Stock delivered upon conversion is then listed or trading; and

(v) no Event of Default shall have occurred and be continuing.

For the avoidance of doubt, subject to the satisfaction of the conditions set forth in this Section 14.02, $1,666,666 aggregate principal amount of Exchange Notes (including PIK Notes) shall convert each month for fifteen consecutive months on a pro rata basis. Simultaneously with the execution of this Indenture, the Company has issued $43,000,000 in aggregate principal amount of 5.0% Voluntary Convertible Senior Notes due 2024 (CUSIP 29266S AC0) (the “ Voluntary Notes ”) pursuant to the Indenture between the Company and the Trustee, dated April 3, 2019 (the “ Voluntary Indenture ”). Upon the completion of (i) the last Mandatory Conversion on or about July 13, 2020, or (ii) on July 13, 2020, if the Company does not elect to make the last Mandatory Conversion on or before July 20, 2020 (such date, as applicable, the “ Exchange Trigger Date ”), the Company shall permit any Notes that remain outstanding to be exchanged into Voluntary Notes (the “ New Voluntary Notes ”). The Company shall use commercially reasonable efforts to assure that the exchange will be accomplished in a manner, such that the New Voluntary Notes will be DTC eligible and otherwise fungible (including with respect to transferability and the payment of interest) with the then outstanding Voluntary Notes

56

so as to bear the same CUSIP number (CUSIP 29266S AC0) as the Voluntary Notes issued on the date hereof. Without limiting the foregoing, the Company will use commercially reasonable efforts to timely comply with all applicable laws, including without limitation, applicable securities laws, in order to ensure that any such exchange may take place on or after the Exchange Trigger Date.

Notwithstanding anything to the contrary in this Indenture, the total principal amount of the Exchange Notes (including PIK Notes) subject to Mandatory Conversion shall not exceed $25,000,000.

Section 14.03. Conversion Procedure; Settlement Upon Conversion .

(a) Subject to this Section 14.03, Section 14.04(b) and Section 14.08(a), upon conversion of any Note pursuant to Section 14.01, the Company shall pay or deliver, as the case may be, to the converting Holder, in respect of each $1.00 principal amount of Notes being converted, cash (“ Cash Settlement ”), shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.03 (“ Physical Settlement ”) or a combination of cash and shares of Common Stock, together with cash, if applicable, in lieu of delivering any fractional share of Common Stock in accordance with subsection (j) of this Section 14.03 (“ Combination Settlement ”), at its election, as set forth in this Section 14.03.

(i) All conversions for which the relevant Conversion Date occurs on or after January 1, 2024 shall be settled using the same Settlement Method.

(ii) Except for any conversions for which the relevant Conversion Date occurs on or after January 1, 2024, the Company shall use the same Settlement Method for all conversions with the same Conversion Date, but the Company shall not have any obligation to use the same Settlement Method with respect to conversions with different Conversion Dates.

(iii) If, in respect of any Conversion Date (or one of the periods described in the third immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a notice (the “ Settlement Notice ”) of the relevant Settlement Method in respect of such Conversion Date (or such period, as the case may be), the Company shall deliver such Settlement Notice to converting Holders, the Trustee and the Conversion Agent (if other than the Trustee) no later than the close of business on the Trading Day immediately following the relevant Conversion Date (or, in the case of any conversions for which the relevant Conversion Date occurs on or after January 1, 2024, no later than January 1, 2024). If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1.00 principal amount of Notes shall be equal to $1.00. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1.00 principal amount of Notes. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its

57

Conversion Obligation but does not indicate a Specified Dollar Amount per $1.00 principal amount of Notes in such Settlement Notice, the Specified Dollar Amount per $1.00 principal amount of Notes shall be deemed to be $1.00.

(iv) The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “ Settlement Amount ”) shall be computed as follows:

(A) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical Settlement, the Company shall deliver to the converting Holder in respect of each $1.00 principal amount of Notes being converted a number of shares of Common Stock equal to the Applicable Conversion Rate in effect on the Conversion Date plus cash in lieu;

(B) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Cash Settlement, the Company shall pay to the converting Holder in respect of each $1.00 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, in respect of each $1.00 principal amount of Notes being converted, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive Trading Days during the related Observation Period plus cash in lieu.

(v) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the Conversion Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b) Subject to Section 14.03(e), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and, if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.03(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “ Notice of Conversion ”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted and the name or names

58

(with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, furnish appropriate endorsements and transfer documents and (4) if required, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled as set forth in Section 14.03(h). The Trustee (and if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article 14 on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03. Notwithstanding anything to the contrary, no holder may deliver a Notice of Conversion (i) during the period of time commencing on the first day of a Mandatory Conversion Calendar Quarter and the open of business on the third Business Day of such Mandatory Conversion Calendar Quarter or (ii) during a Mandatory Conversion Calendar Quarter in which the Company has delivered a Mandatory Conversion Notice.

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

(c) A Note shall be deemed to have been converted immediately prior to the close of business on the date (the “ Conversion Date ”) that the Holder has complied with the requirements set forth in subsection (b) above. Except as set forth in Section 14.04(b) and Section 14.08(a), the Company shall pay or deliver, as the case may be, the consideration due in respect of the Conversion Obligation on the second Business Day immediately following the relevant Conversion Date, if the Company elects Physical Settlement, or on the second Business Day immediately following the last Trading Day of the Observation Period, in the case of any other Settlement Method. If any shares of Common Stock are due to a converting Holder, the Company shall issue or cause to be issued, and deliver to the stock transfer agent or to such Holder, or such Holder’s nominee or nominees, the full number of shares of Common Stock to which such Holder shall be entitled, in book-entry format through the Depositary, in satisfaction of the Company’s Conversion Obligation.

(d) In case any Physical Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Physical Note so surrendered a new Physical Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Physical Note, without payment of any service charge by the converting Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Physical Notes issued upon such conversion being different from the name of the Holder of the old Physical Notes surrendered for such conversion.

59

(e) If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The stock transfer agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f) Except as provided in Section 14.05, no adjustment shall be made for dividends on any shares of Common Stock issued upon the conversion of any Note as provided in this Article 14.

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

(h) Upon conversion, except as set forth in Section 14.02, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any, except as set forth below. The Company’s settlement of the full Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the close of business on a Regular Record Date, Holders of such Notes as of the close of business on such Regular Record Date will receive the full amount of interest payable on such Notes (including a PIK Payment, if applicable) on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any Regular Record Date to the open of business on the immediately following Interest Payment Date, however, must be accompanied by funds equal to the amount of interest payable on the Notes so converted (regardless of whether a PIK Payment will be made or shares of common stock will be issued, and in the event of a PIK Payment or distribution of shares of common stock, the interest payable will be the cash equivalent of any PIK Payment); provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the Business Day immediately following the corresponding Interest Payment Date; or (3) to the extent of any Defaulted Amounts, if any Defaulted Amounts exists at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date in cash regardless of whether their Notes have been converted following such Regular Record Date.

(i) The Person in whose name the shares of Common Stock shall be issuable upon conversion shall be treated as a stockholder of record as of the close of business on the relevant

60

Conversion Date (if the Company elects to satisfy the related Conversion Obligation by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Conversion Obligation by Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

(j) The Company shall not issue any fractional share of Common Stock upon conversion of the Notes and shall instead pay cash in lieu of delivering any fractional share of Common Stock issuable upon conversion based on the Daily VWAP for the relevant Conversion Date (in the case of Physical Settlement) or based on the Daily VWAP for the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for conversion, if the Company has elected Combination Settlement, the full number of shares that shall be issued upon conversion thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 14.04. Increased Applicable Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes . (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date, and a Holder elects to convert its Notes in connection with such Make-Whole Fundamental Change, the Company shall, under the circumstances described below, increase the Applicable Conversion Rate for the Notes so surrendered for conversion by a number of additional shares of Common Stock (the “ Additional Shares ”), as described below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent 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 proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change) (such period, the “ Make-Whole Fundamental Change Period ”).

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to Section 14.01(b)(iii), the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 14.03; provided , however , that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1.00 principal amount of converted Notes equal to the Applicable Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes, the Trustee and the Conversion Agent of the Effective Date of any Make-Whole Fundamental Change and issue a press release announcing such Effective Date no later than five Business Days after such Effective Date.

61

(c) The number of Additional Shares, if any, by which the Applicable Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (in each case, the “ Effective Date ”), and the price paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change (the “ Stock Price ”). 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 of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change. The Board of Directors shall make appropriate adjustments to the Stock Price, in its good faith determination, to account for any adjustment to the Applicable Conversion Rate that becomes effective, or any event requiring an adjustment to the Applicable Conversion Rate where the Ex-Dividend Date, Effective Date (as such term is used in Section 14.05) or expiration date of the event occurs during such five consecutive Trading Day period.

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Applicable Conversion Rate of the Notes is otherwise adjusted. 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 Applicable Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Applicable Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Applicable Conversion Rate as set forth in Section 14.05.

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Applicable Conversion Rate shall be increased per $1.00 principal amount of Notes pursuant to this Section 14.04 for each Stock Price and Effective Date set forth below:

The exact Stock Price and Effective Date may not be set forth in the table above, in which case:

(i) if the Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table, the number of Additional Shares shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;

62

(ii) if the Stock Price is greater than $40.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Applicable Conversion Rate; and

(iii) if the Stock Price is less than $6.61 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Applicable Conversion Rate.

Notwithstanding the foregoing, in no event shall the Applicable Conversion Rate per $1.00 principal amount of Notes exceed 0.1512 shares of Common Stock, subject to adjustment in the same manner as the Applicable Conversion Rate pursuant to Section 14.05.

(f) Nothing in this Section 14.04 shall prevent an adjustment to the Applicable Conversion Rate pursuant to Section 14.05 in respect of a Make-Whole Fundamental Change.

Section 14.05. Adjustment of Indenture Conversion Rates . The Indenture Conversion Rates shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Indenture Conversion Rates if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 14.05, without having to convert their Notes, as if they held a number of shares of Common Stock equal to the Indenture Conversion Rates, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company issues shares of Common Stock as a dividend or distribution on shares of the Common Stock, or if the Company effects a share split or share combination, the Indenture Conversion Rates shall be adjusted based on the following formula:

where,

63

Any adjustment made under this Section 14.05(a) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 14.05(a) is declared but not so paid or made, the Indenture Conversion Rates shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Indenture Conversion Rates that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company issues to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Indenture Conversion Rates shall be increased based on the following formula:

where,

Any increase made under this Section 14.05(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the Ex-Dividend Date for such issuance. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or warrants, the Indenture

64

Conversion Rates shall be decreased to the Indenture Conversion Rates 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 Indenture Conversion Rates shall be decreased to the Indenture Conversion Rates that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 14.05(b) and for the purpose of Section 14.01(b)(ii)(A), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at less than such average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors.

(c) 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 its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 14.05(a) or Section 14.05(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section 14.05(d) shall apply, (iii) except as otherwise provided in Section 14.12, rights issued under a stockholder rights plan of the Company, (iv) distributions of Reference Property in exchange for or upon conversion of the Common Stock in a Share Exchange Event and (v) Spin-Offs as to which the provisions set forth below in this Section 14.05(c) shall apply (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to acquire Capital Stock or other securities, the “ Distributed Property ”), then the Indenture Conversion Rates shall be increased based on the following formula:

where,

65

Any increase made under the portion of this Section 14.05(c) above shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate; provided that if such distribution is not so paid or made, the Indenture Conversion Rates shall be decreased to the Indenture Conversion Rates that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1.00 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Indenture Conversion Rates in effect on the Ex-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.05(c) 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 Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 14.05(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 a Subsidiary or other business unit of the Company, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “ Spin-Off ”), the Indenture Conversion Rates shall be increased based on the following formula:

where,

66

The adjustment to the Indenture Conversion Rates under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the Conversion Date in determining the Indenture Conversion Rates and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the Valuation Period, references to “10” in the preceding paragraph shall be deemed to be replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and such Trading Day in determining the Indenture Conversion Rates as of such Trading Day. If the Ex-Dividend Date of the Spin-Off is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Ex-Dividend Date for the Spin-Off to, and including, the last Trading Day of such Observation Period.

For purposes of this Section 14.05(c) (and subject in all respect to Section 14.12), rights, options or warrants distributed by the Company to all or substantially all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“ Trigger Event ”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 14.05(c) (and no adjustment to the Indenture Conversion Rates under this Section 14.05(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Indenture Conversion Rates shall be made under this Section 14.05(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Indenture Conversion Rates under this Section 14.05(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final purchase (x) the Indenture Conversion Rates shall be readjusted

67

as if such rights, options or warrants had not been issued and (y) the Indenture Conversion Rates shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Indenture Conversion Rates shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 14.05(a), Section 14.05(b) and this Section 14.05(c), if any dividend or distribution to which this Section 14.05(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 14.05(a) is applicable (the “ Clause A Distribution ”); or

(B) a dividend or distribution of rights, options or warrants to which Section 14.05(b) is applicable (the “ Clause B Distribution ”),

then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.05(c) is applicable (the “ Clause C Distribution ”) and any Indenture Conversion Rates adjustment required by this Section 14.05(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Indenture Conversion Rates adjustment required by Section 14.05(a) and Section 14.05(b) with respect thereto shall then be made, except that, if determined by the Company (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on such Ex-Dividend Date or Effective Date” within the meaning of Section 14.05(a) or “outstanding immediately prior to the open of business on such Ex-Dividend Date” within the meaning of Section 14.05(b).

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

where,

68

Any increase pursuant to this Section 14.05(d) shall become effective immediately after the open of business on the Ex-Dividend Date for such dividend or distribution. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate; provided that if such dividend or distribution is not so paid, the Indenture Conversion Rates shall be decreased, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Indenture Conversion Rates that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1.00 principal amount of Notes, at the same time and upon the same terms as holders of shares of the Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Indenture Conversion Rates on the Ex-Dividend Date for such cash dividend or distribution.

(e) If the Company or any of its Subsidiaries make a payment in respect of a tender 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 the Common Stock exceeds the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Indenture Conversion Rates shall be increased based on the following formula:

where,

69

The increase to the Indenture Conversion Rates under this Section 14.05(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that (x) in respect of any conversion of Notes for which Physical Settlement is applicable, if the relevant Conversion Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date that such tender or exchange offer expires and the Conversion Date in determining the Indenture Conversion Rates and (y) in respect of any conversion of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such conversion and within the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in the preceding paragraph shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and such Trading Day in determining the Indenture Conversion Rates as of such Trading Day. In addition, if the Trading Day next succeeding the date such tender or exchange offer expires is after the 10th Trading Day immediately preceding, and including, the end of any Observation Period in respect of a conversion of Notes, references to “10” or “10th” in the preceding paragraph and this paragraph shall be deemed to be replaced, solely in respect of that conversion of Notes, with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and including, the last Trading Day of such Observation Period. No adjustment pursuant to the above formula shall result in a decrease of the Conversion Rate. If the Company or any of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender offer or exchange offer, but the Company or any of its Subsidiaries is ultimately prevented by applicable law from effecting all or any portion of such purchases or all or any portion of such purchases are rescinded, the Conversion Rate shall immediately be readjusted to be the Conversion Rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchase of Common Stock that had been effected.

(f) Notwithstanding this Section 14.05 or any other provision of this Indenture or the Notes, if a Indenture Conversion Rates adjustment becomes effective on any Ex-Dividend Date,

70

and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the shares of Common Stock as of the related Conversion Date as described under Section 14.03(i) based on an adjusted Indenture Conversion Rates for such Ex-Dividend Date, then, notwithstanding the Indenture Conversion Rates adjustment provisions in this Section 14.05, the Indenture Conversion Rates adjustment relating to such Ex-Dividend Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(g) Except as stated herein, the Company shall not adjust the Indenture Conversion Rates for the issuance of shares of the Common Stock or any securities convertible into or exchangeable for shares of the Common Stock or the right to purchase shares of the Common Stock or such convertible or exchangeable securities.

(h) In addition to those adjustments required by clauses (a), (b), (c), (d) and (e) of this Section 14.05, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company from time to time may increase the Indenture Conversion Rates by any amount for a period of at least 20 Business Days if the Board of Directors determines that such increase would be in the Company’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of the Company’s securities are then listed, the Company may (but is not required to) increase the Indenture Conversion Rates to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock in connection with a dividend or distribution of shares of Common Stock (or rights to acquire shares of Common Stock) or similar event. Whenever the Indenture Conversion Rates is increased pursuant to either of the preceding two sentences, the Company shall deliver to the Holder of each Note a notice of the increase at least 15 days prior to the date the increased Indenture Conversion Rates takes effect, and such notice shall state the increased Indenture Conversion Rates and the period during which it will be in effect.

(i) Notwithstanding anything to the contrary in this Article 14, the Indenture Conversion Rates shall 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 the Company’s Subsidiaries;

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

71

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

(v) for accrued and unpaid interest, if any.

(j) All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearest one-ten thousandth (1/10,000th) of a share. The Company shall not be required to make an adjustment in the Conversion Rate unless the adjustment would require a change of at least 1% in the Conversion Rate; provided that the Company shall carry forward any adjustment that is less than 1% of the Conversion Rate, take such carried-forward adjustments into account in any subsequent adjustment, and make such carried forward adjustments, regardless of whether the aggregate adjustment is less than 1%, (i) on the Conversion Date for any Notes, (ii) on each Trading Day of the Conversion Period in respect of any Notes, and (iii) on any Fundamental Change effective date, unless such adjustment has already been made.

(k) Whenever the Indenture Conversion Rates is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Conversion Agent if not the Trustee) an Officers’ Certificate setting forth the Indenture Conversion Rates after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officers’ Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Indenture Conversion Rates and may assume without inquiry that the last Indenture Conversion Rates of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Indenture Conversion Rates setting forth the adjusted Indenture Conversion Rates and the date on which each adjustment becomes effective and shall deliver such notice of such adjustment of the Indenture Conversion Rates to each Holder. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(l) For purposes of this Section 14.05, the number of shares of Common Stock at any time outstanding shall not include shares of Common Stock held in the treasury of the Company 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, but shall include shares of Common Stock issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 14.06. Adjustments of Prices . Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts over a span of multiple days (including an Observation Period and the period for determining the Stock Price for purposes of a Make-Whole Fundamental Change), the Board of Directors shall make appropriate adjustments to each to account for any adjustment to the Applicable Conversion Rate that becomes effective, or any event requiring an adjustment to the Applicable Conversion Rate where the Ex-Dividend Date, Effective Date or expiration date, as the case may be, of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated.

Section 14.07. Shares to Be Fully Paid . The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for conversion of the Notes from time to time as such Notes

72

are presented for conversion (assuming delivery of the maximum number of Additional Shares pursuant to Section 14.04 and that at the time of computation of such number of shares, all such Notes would be converted by a single Holder and that Physical Settlement were applicable).

Section 14.08. Effect of Recapitalizations, Reclassifications and Changes of the Common Stock .

(a) In the case of:

(i) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or combination or a change of par value or to no par value),

(ii) any consolidation, merger, combination or similar transaction involving the Company,

(iii) any sale, assignment, conveyance, lease or other transfer to a third party of the consolidated assets of the Company and the Company’s Subsidiaries substantially as an entirety or

(iv) any statutory share exchange,

in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “ Share Exchange Event ”), then, at and after the effective time of such Share Exchange Event, the right to convert each $1.00 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Applicable Conversion Rate immediately prior to such Share Exchange Event would have owned or been entitled to receive (the “ Reference Property ,” with each “ unit of Reference Property ” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Share Exchange Event and, prior to or at the effective time of such Share Exchange Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(g) providing for such change in the right to convert each $1.00 principal amount of Notes; provided , however , that at and after the effective time of the Share Exchange Event (A) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon conversion of Notes in accordance with Section 14.03 and (B) (I) any amount payable in cash upon conversion of the Notes in accordance with Section 14.03 shall continue to be payable in cash, (II) any shares of Common Stock that the Company would have been required to deliver upon conversion of the Notes in accordance with Section 14.03 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have been entitled to receive in such Share Exchange Event and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Share Exchange Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in

73

part upon any form of stockholder election), then (i) the Reference Property into which the Notes will be convertible shall be deemed to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. If the holders of the Common Stock receive only cash in such Share Exchange Event, then for all conversions for which the relevant Conversion Date occurs after the effective date of such Share Exchange Event (A) the consideration due upon conversion of each $1.00 principal amount of Notes shall be solely cash in an amount equal to the Applicable Conversion Rate in effect on the Conversion Date (as may be increased by any Additional Shares pursuant to Section 14.04), multiplied by the price paid per share of Common Stock in such Share Exchange Event and (B) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the relevant Conversion Date. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for anti-dilution and other adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If, in the case of any Share Exchange Event, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the successor or purchasing corporation, as the case may be, in such Share Exchange Event, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15.

(b) When the Company executes a supplemental indenture pursuant to subsection (a) of this Section 14.08, the Company shall promptly file with the Trustee an Officers’ Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Share Exchange Event, any adjustment to be made with respect thereto and that all conditions precedent have been complied with, and shall promptly deliver notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be delivered to each Holder within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) The Company shall not become a party to any Share Exchange Event unless its terms are consistent with this Section 14.08. None of the foregoing provisions shall affect the right of a holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election, as set forth in Section 14.01 and Section 14.03 prior to the effective date of such Share Exchange Event.

(d) The above provisions of this Section shall similarly apply to successive Share Exchange Events.

74

Section 14.09. Certain Covenants . (a) The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

(b) The Company covenants that, if any shares of Common Stock to be provided for the purpose of conversion of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Common Stock may be validly issued upon conversion, the Company will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

(c) The Company further covenants that if at any time the Common Stock shall be listed on any national securities exchange or automated quotation system the Company will list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, any Common Stock issuable upon conversion of the Notes.

Section 14.10. Responsibility of Trustee . The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Applicable Conversion Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Applicable Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Note; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.08 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Notes after any event referred to in such Section 14.08 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether any event contemplated by Section 14.01(b) has occurred that makes the Notes eligible for conversion or no longer eligible therefor until the Company has delivered to the Trustee and the Conversion Agent the notices referred to in Section 14.01(b) with respect to the commencement or termination of such conversion rights, on which notices the Trustee and the Conversion Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01(b).

Section 14.11. Notice to Holders Prior to Certain Actions . In case of any:

75

(a) action by the Company or one of its Subsidiaries that would require an adjustment in the Applicable Conversion Rate pursuant to Section 14.05 or Section 14.12;

(b) Share Exchange Event; or

(c) voluntary or involuntary dissolution, liquidation or winding-up of the Company or any of its Subsidiaries;

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Conversion Agent (if other than the Trustee) and to be delivered to each Holder, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company or one of its Subsidiaries or, if a record is not to be taken, the date as of which the holders of Common Stock of record are to be determined for the purposes of such action by the Company or one of its Subsidiaries, or (ii) the date on which such Share Exchange Event, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such Share Exchange Event, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such action by the Company or one of its Subsidiaries, Share Exchange Event, dissolution, liquidation or winding-up.

Section 14.12. Stockholder Rights Plans . If the Company has a stockholder rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon such conversion shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Common Stock issued upon such conversion shall bear such legends, if any, in each case as may be provided by the terms of any such stockholder rights plan, as the same may be amended from time to time. However, if, prior to any conversion of Notes, the rights have separated from the shares of Common Stock in accordance with the provisions of the applicable stockholder rights plan, the Applicable Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of the Common Stock Distributed Property as provided in Section 14.05(c), subject to readjustment in the event of the expiration or termination of such rights.

Section 14.13. Ownership Limitation .

(a) Notwithstanding the provisions of Section 14.01, during any period of time in which a Holder’s “beneficial ownership” (as determined in accordance with Rule 13d-3 of the Exchange Act) of Common Stock is less than 9.5%, the Holder shall not have the right to voluntarily convert, and the Company shall not effect a Mandatory Conversion, of all or any portion of the Notes, and shall not be entitled to receive shares of Common Stock in exchange therefore, if (but only to the extent that) upon and after giving effect to such conversion (and issuance of any shares of Common Stock in satisfaction of any Fundamental Change or Make-Whole Fundamental Change, as the case may be), and taking into account the method of settlement elected by (or deemed to have been elected by) the Company under Section 14.03, such Holder (together with such Holder’s Affiliated Parties (including shares held by any “group” of which the Holder or any of its Affiliates and any other persons or entities whose

76

beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (the  “Affiliated Parties” ) (including shares held by any “group” of which the Holder or any of its Affiliated Parties is a member)) would have beneficial ownership of more than 9.5% of the total number of shares of Common Stock then issued and outstanding (the  “Ownership Limitation” );  provided,  that, a Holder may, at its option and upon not less than sixty-one (61) days’ prior notice to the Company, elect to increase the Ownership Limitation up to 19.99% of the total number of shares of Common Stock then issued and outstanding. Any such increase will not be effective until the 61st day after such notice is delivered to the Company. The Company hereby covenants and agrees not to adopt any shareholder rights plan or take any other action which would have the effect of restricting or adversely affecting the Holder’s election to change such threshold percentage. When submitting any Conversion Notice through the applicable procedures of the Depositary, such holder shall be deemed to represent and warrant that such conversion will not result in a breach of the Ownership Limitation.

The Trustee and the Conversion Agent shall have no obligation to monitor a Holder’s beneficial ownership of Common Stock or the Ownership Limitation and shall have no liability for conversions made by beneficial owners exceeding the Ownership Limitation.

(b) For the avoidance of doubt, if a Holder, pursuant to Section 14.01(a), or the Company, pursuant to Section 14.02, purports to convert the Principal Amount of any Notes into shares of Common Stock hereunder and any delivery otherwise owed to such Holder hereunder is not made, in whole or in part, as a result of the Ownership Limitation or any other limitation set forth herein, then the Holder’s rights under the relevant Notes, or portion thereof, pursuant to which such delivery was not made will not be extinguished and, instead such Notes, or portion thereof, will be deemed to have never been converted.

ARTICLE 15

R EPURCHASE OF N OTES AT O PTION OF H OLDERS

Section 15.01. [Intentionally Omitted] .

Section 15.02. Repurchase at Option of Holders Upon a Fundamental Change . (a) If a Fundamental Change occurs at any time, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to $1.00 or an integral multiple of $1.00, on the date (the “ Fundamental Change Repurchase Date ”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “ Fundamental Change Repurchase Price ”), unless the Fundamental Change Repurchase Date falls after a Regular Record Date but on or prior to the Interest Payment Date to which such Regular Record Date relates, in which case the Company shall instead pay the full amount of accrued and unpaid interest to Holders of record as of such Regular Record Date, and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased pursuant to this Article 15.

77

(b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon:

(i) delivery to the Paying Agent or tender agent appointed by the Company to facilitate the repurchase (the “ Tender Agent ”) by a Holder of a duly completed notice (the “ Fundamental Change Repurchase Notice ”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case on or before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date; and

(ii) delivery of the Notes, if the Notes are Physical Notes, to the Paying Agent or Tender Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements for transfer) at the Corporate Trust Office of the Paying Agent or the principal office of the Tender Agent located in the contiguous United States as notified by the Tender Agent to Holders and the Trustee, as the case may be, or book-entry transfer of the Notes, if the Notes are Global Notes, in compliance with the procedures of the Depositary, in each case such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor.

The Fundamental Change Repurchase Notice in respect of any Notes to be repurchased shall state:

(i) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(ii) the portion of the principal amount of Notes to be repurchased, which must be $1.00 or an integral multiple thereof; and

(iii) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture;

provided , however , that if the Notes are Global Notes, the Fundamental Change Repurchase Notice must comply with appropriate Depositary procedures.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent or Tender Agent, as the case may be, the Fundamental Change Repurchase Notice contemplated by this Section 15.02 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent or Tender Agent, as the case may be, in accordance with Section 15.03.

The Paying Agent or Tender Agent, as the case may be, shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

78

(c) On or before the fifth (5th) Business Day after the occurrence of the effective date of a Fundamental Change, the Company shall provide to all Holders of Notes and the Trustee, Conversion Agent (in the case of a Conversion Agent other than the Trustee) and the Paying Agent (in the case of a Paying Agent other than the Trustee) a notice (the “ Fundamental Change Company Notice ”) of the occurrence of the effective date of the Fundamental Change and of the repurchase right at the option of the Holders arising as a result thereof. In the case of Physical Notes, such notice shall be by first class mail or, in the case of Global Notes, such notice shall be delivered in accordance with the applicable procedures of the Depositary. Simultaneously with providing such notice, the Company shall publish a notice containing the information set forth in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish such information on the Company’s website or through such other public medium as the Company may use at that time. Each Fundamental Change Company Notice shall specify:

(i) the events causing the Fundamental Change and whether such Fundamental Change is a Make-Whole Adjustment Event;

(ii) the date of the Fundamental Change;

(iii) the last date on which a Holder may exercise the repurchase right pursuant to this Article 15;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of the Paying Agent or Tender Agent, as the case may be, and the Conversion Agent, if applicable;

(vii) if applicable, the Applicable Conversion Rate and any adjustments to the Applicable Conversion Rate;

(viii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

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

No failure of the Company to give the foregoing notices and no defect therein shall limit the Holders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 15.02.

At the Company’s request, delivered at least two Business Days prior to the Fundamental Change Company Notice is to be sent, the Trustee shall give such notice in the Company’s name and at the Company’s expense; provided , however , that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company.

79

(d) Notwithstanding the foregoing, no Notes may be repurchased by the Company on any date at the option of the Holders upon a Fundamental Change if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes). The Paying Agent or Tender Agent, as the case may be, will promptly return to the respective Holders thereof any Physical Notes held by it during the acceleration of the Notes (except in the case of an acceleration resulting from a Default by the Company in the payment of the Fundamental Change Repurchase Price with respect to such Notes), or any instructions for book-entry transfer of the Notes in compliance with the procedures of the Depositary shall be deemed to have been cancelled, and, upon such return or cancellation, as the case may be, the Fundamental Change Repurchase Notice with respect thereto shall be deemed to have been withdrawn.

Section 15.03. Withdrawal of Fundamental Change Repurchase Notice .
