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 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

4

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.

(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

5

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.

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT DATED AS OF AUGUST 9, 2018, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.”

(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” (as defined in Rule 144 under the Securities Act), or (E) if such legend is not required under applicable requirements of the

6

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 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

7

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

8

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 $4.71 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 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

(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 Additional Warrant 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 Additional Warrant Registration Deadline (as defined in the Registration Rights Agreement), and if such Registration Statement does not become effective prior to the Additional Warrant 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 any one 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 any one 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

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

“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.

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT DATED AS OF AUGUST 9, 2018, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.”

(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” (as defined in Rule 144 under the Securities Act), or (E) if such legend is not required under applicable requirements of the

6

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 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

7

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 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 $4.71 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 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 Additional Warrant 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 Additional Warrant Registration Deadline (as defined in the Registration Rights Agreement), and if such Registration Statement does not become effective prior to the Additional Warrant 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 any one 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 any one 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.

12. Holder’s Early Terminations .

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 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 .

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 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

4

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.

(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

5

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.

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT DATED AS OF AUGUST 9, 2018, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.”

(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” (as defined in Rule 144 under the Securities Act), or (E) if such legend is not required under applicable requirements of the

6

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 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

7

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

(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

9

(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 (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 .

11

surrender of this Warrant properly completed and endorsed.

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 Additional Warrant 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 Additional Warrant Registration Deadline (as defined in the Registration Rights Agreement), and if such Registration Statement does not become effective prior to the Additional Warrant 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 any one 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 any one 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.

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 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 Exercise Period 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 .

23

Nothing in this Warrant shall be construed to confer upon any person other than the Company and Holder any legal or equitable right, remedy or claim under this Warrant and this Warrant shall be for the sole and exclusive benefit of the Company and Holder.

15. Governing Law .

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, provided the Unrestricted Condition is satisfied), then, in addition to all other available remedies that the Lender may 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 such 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 such Lender (in addition to all other available remedies that the Lender may otherwise have), 110% of the amount by which (A) such Lender’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares exceeds (B) the net proceeds received by such 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 specified by the Lender in the Conversion Notice.

(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 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; provided , that the voiding of the Lender’s 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 may

7

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.

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 conversion of this Note 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.

(ii) Conversion Issuance Limit . Notwithstanding anything to the contrary contained herein, the Borrower shall not issue any shares of Common Stock upon conversion of this Note (including pursuant to Section  2(c)(v)(A) hereof) to the extent that the issuance of such shares of Common Stock together with any previous issuances of shares of Common Stock under this Note would exceed the Conversion Issuance Limit, and Section 2.5(c)(v) shall not apply in respect to any excess amount.

(iii) Other Applicable Limitations on Conversion of the Note . Notwithstanding anything to the contrary herein, this Note shall not be convertible, and the Borrower shall not issue shares of Common Stock upon conversion of this Note (a) at any time after the First Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the First Amortization Date, would exceed the First Amortization Cap, or (b)  at any time after the Second Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the Second Amortization

Date, would exceed the Second Amortization Cap, or (c) during any Monthly Conversion Cap Period, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares previously issued to Lender upon conversion of this Note during the such Monthly Conversion Cap Period, would exceed the Monthly Conversion Cap. For the avoidance of doubt, if the number of shares of Common Stock to be issued as set forth in an Conversion Notice transmitted by the Lender to the Borrower would otherwise require the Borrower to issue a number of shares in excess of the Conversion Issuance Limit, the First Amortization Cap (if after the First Amortization Date), the Second Amortization Cap (if after the Second Amortization Date) or the Monthly Share Cap, the Borrower shall issue to the Lender in accordance herewith the maximum number of shares of Common Stock issuable without exceeding any such applicable limitation, and Section 2.5(c)(v) shall not apply to any excess amount.

3. Voting Rights . Except as required by law, the Lender shall have no voting rights with respect to any of the Conversion Shares until the Conversion Date relating to the conversion of this Note upon which such Conversion Shares are issuable (or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section  2(c)(iii) , the first Business Day after the resolution of such bona fide dispute).

4. Amendment; Waiver . The provisions of this Note may only be waived or amended, restated, supplemented or otherwise modified in accordance with the Facility Agreement.

6. Failure or Indulgence Not Waiver . No delay or omission by the Lender in exercising any power or right hereunder shall impair such right or power or be construed to be a waiver of any default, nor shall any single or partial exercise of any power or right hereunder preclude the full exercise thereof or the exercise of any other power or right. No renewal or extension of this Note or the Facility Agreement, no delay in the enforcement of payment under this Note or the Facility Agreement, and no delay or omission in exercising any right or power under this Note or the Facility Agreement shall affect the liability of the Borrower or any endorser of this Note.

9. Payment of Collection, Enforcement and Other Costs .

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, provided the Unrestricted Condition is satisfied), then, in addition to all other available remedies that the Lender may 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 such 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 such Lender (in addition to all other available remedies that the Lender may otherwise have), 110% of the amount by which (A) such Lender’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares exceeds (B) the net proceeds received by such 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 specified by the Lender in the Conversion Notice.

(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 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; provided , that the voiding of the Lender’s 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 may

7

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.

(d) Limitations on Conversions .

(i) Beneficial Ownership . 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 conversion of this Note 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.

(ii) Conversion Issuance Limit . Notwithstanding anything to the contrary contained herein, the Borrower shall not issue any shares of Common Stock upon conversion of this Note (including pursuant to Section  2(c)(v)(A) hereof) to the extent that the issuance of such shares of Common Stock together with any previous issuances of shares of Common Stock under this Note would exceed the Conversion Issuance Limit, and Section 2.5(c)(v) shall not apply in respect to any excess amount.

(iii) Other Applicable Limitations on Conversion of the Note . Notwithstanding anything to the contrary herein, this Note shall not be convertible, and the Borrower shall not issue shares of Common Stock upon conversion of this Note (a) at any time after the First Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the First Amortization Date, would exceed the First Amortization Cap, or (b)  at any time after the Second Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the Second Amortization

8

Date, would exceed the Second Amortization Cap, or (c) during any Monthly Conversion Cap Period, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares previously issued to Lender upon conversion of this Note during the such Monthly Conversion Cap Period, would exceed the Monthly Conversion Cap. For the avoidance of doubt, if the number of shares of Common Stock to be issued as set forth in an Conversion Notice transmitted by the Lender to the Borrower would otherwise require the Borrower to issue a number of shares in excess of the Conversion Issuance Limit, the First Amortization Cap (if after the First Amortization Date), the Second Amortization Cap (if after the Second Amortization Date) or the Monthly Share Cap, the Borrower shall issue to the Lender in accordance herewith the maximum number of shares of Common Stock issuable without exceeding any such applicable limitation, and Section 2.5(c)(v) shall not apply to any excess amount.

3. Voting Rights . Except as required by law, the Lender shall have no voting rights with respect to any of the Conversion Shares until the Conversion Date relating to the conversion of this Note upon which such Conversion Shares are issuable (or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section  2(c)(iii) , the first Business Day after the resolution of such bona fide dispute).

4. Amendment; Waiver . The provisions of this Note may only be waived or amended, restated, supplemented or otherwise modified in accordance with the Facility Agreement.

5. Specific Shall Not Limit General; Construction . No specific provision contained in this Note shall limit or modify any more general provision contained herein.

6. Failure or Indulgence Not Waiver . No delay or omission by the Lender in exercising any power or right hereunder shall impair such right or power or be construed to be a waiver of any default, nor shall any single or partial exercise of any power or right hereunder preclude the full exercise thereof or the exercise of any other power or right. No renewal or extension of this Note or the Facility Agreement, no delay in the enforcement of payment under this Note or the Facility Agreement, and no delay or omission in exercising any right or power under this Note or the Facility Agreement shall affect the liability of the Borrower or any endorser of this Note.

This Note is not (and any rights or obligations hereunder are not) not assignable or transferable by the Borrower under any circumstance and any such prohibited assignment or transfer is absolutely void ab initio .

9. Payment of Collection, Enforcement and Other Costs . If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding; or (b) an attorney is retained to represent the Lender in any bankruptcy, reorganization, receivership of the Borrower or other proceedings affecting Borrower creditors’ rights and involving a claim under this Note, then the Borrower shall pay the costs incurred by the Lender for such collection, enforcement or action, including reasonable attorneys’ fees and disbursements.

Notwithstanding the existence of a dispute contemplated by this paragraph, if requested by the Lender, the Borrower shall issue to the Lender the Conversion Shares not in dispute in accordance with the terms hereof.

(iv) Record Holder . The person or persons entitled to receive the Conversion Shares issuable upon a conversion of this Note shall be treated for all purposes as the legal and record holder or holders of such shares of Common Stock upon delivery by the Lender of the Conversion Notice, or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section  2(c)(iii) , the first Business Day after the resolution of such bona fide dispute.

(v) Borrower’s Failure to Timely Convert .

6

(A) Cash Damages . 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, provided the Unrestricted Condition is satisfied), then, in addition to all other available remedies that the Lender may 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 such 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 such Lender (in addition to all other available remedies that the Lender may otherwise have), 110% of the amount by which (A) such Lender’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares exceeds (B) the net proceeds received by such 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 specified by the Lender in the Conversion Notice.

(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 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; provided , that the voiding of the Lender’s 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 may

7

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.

(d) Limitations on Conversions .

(i) Beneficial Ownership . 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 conversion of this Note 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.

(ii) Conversion Issuance Limit . Notwithstanding anything to the contrary contained herein, the Borrower shall not issue any shares of Common Stock upon conversion of this Note (including pursuant to Section  2(c)(v)(A) hereof) to the extent that the issuance of such shares of Common Stock together with any previous issuances of shares of Common Stock under this Note would exceed the Conversion Issuance Limit, and Section 2.5(c)(v) shall not apply in respect to any excess amount.

(iii) Other Applicable Limitations on Conversion of the Note . Notwithstanding anything to the contrary herein, this Note shall not be convertible, and the Borrower shall not issue shares of Common Stock upon conversion of this Note (a) at any time after the First Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the First Amortization Date, would exceed the First Amortization Cap, or (b)  at any time after the Second Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the Second Amortization

8

Date, would exceed the Second Amortization Cap, or (c) during any Monthly Conversion Cap Period, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares previously issued to Lender upon conversion of this Note during the such Monthly Conversion Cap Period, would exceed the Monthly Conversion Cap. For the avoidance of doubt, if the number of shares of Common Stock to be issued as set forth in an Conversion Notice transmitted by the Lender to the Borrower would otherwise require the Borrower to issue a number of shares in excess of the Conversion Issuance Limit, the First Amortization Cap (if after the First Amortization Date), the Second Amortization Cap (if after the Second Amortization Date) or the Monthly Share Cap, the Borrower shall issue to the Lender in accordance herewith the maximum number of shares of Common Stock issuable without exceeding any such applicable limitation, and Section 2.5(c)(v) shall not apply to any excess amount.

3. Voting Rights . Except as required by law, the Lender shall have no voting rights with respect to any of the Conversion Shares until the Conversion Date relating to the conversion of this Note upon which such Conversion Shares are issuable (or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section  2(c)(iii) , the first Business Day after the resolution of such bona fide dispute).

4. Amendment; Waiver . The provisions of this Note may only be waived or amended, restated, supplemented or otherwise modified in accordance with the Facility Agreement.

5. Specific Shall Not Limit General; Construction . No specific provision contained in this Note shall limit or modify any more general provision contained herein. This Note shall be deemed to be jointly drafted by the Borrower and all Lenders pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof.

6. Failure or Indulgence Not Waiver . No delay or omission by the Lender in exercising any power or right hereunder shall impair such right or power or be construed to be a waiver of any default, nor shall any single or partial exercise of any power or right hereunder preclude the full exercise thereof or the exercise of any other power or right. No renewal or extension of this Note or the Facility Agreement, no delay in the enforcement of payment under this Note or the Facility Agreement, and no delay or omission in exercising any right or power under this Note or the Facility Agreement shall affect the liability of the Borrower or any endorser of this Note.

7. Notices . Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be given in accordance with Section 6.1 of the Facility Agreement.

8. Restrictions on Transfer .

This Note is not (and any rights or obligations hereunder are not) not assignable or transferable by the Borrower under any circumstance and any such prohibited assignment or transfer is absolutely void ab initio .

9. Payment of Collection, Enforcement and Other Costs . If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding; or (b) an attorney is retained to represent the Lender in any bankruptcy, reorganization, receivership of the Borrower or other proceedings affecting Borrower creditors’ rights and involving a claim under this Note, then the Borrower shall pay the costs incurred by the Lender for such collection, enforcement or action, including reasonable attorneys’ fees and disbursements. Subject to the terms of the Facility Agreement, all payments and issuances of shares of Common Stock hereunder will be free and clear of, and without deduction or withholding for, any present or future taxes.

If the Lender and the Borrower are unable to agree upon the determination of the Conversion Price or arithmetic calculation of the Conversion Rate within one (1) Business Day of such disputed determination or arithmetic calculation being transmitted to the Lender, then the Borrower shall promptly (and in any event within two (2) Business Days) submit via facsimile (A) the disputed determination of the Conversion Price to an independent, reputable investment banking firm agreed to by the Borrower and the Required Lenders, or (B) the disputed arithmetic calculation of the Conversion Rate to the Borrower’s independent registered public accounting firm, as the case may be. The Borrower shall direct the investment bank or the accounting firm, as the case may be, to perform the determinations or calculations and notify the Borrower and the Lender of the results no later than two (2) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accounting firm’s determination or calculation, as the case may be, shall be binding upon all parties absent manifest error, and the fees and expenses of such investment bank or accountant shall be paid one-half by the Borrower and one-half by the Lender. Notwithstanding the existence of a dispute contemplated by this paragraph, if requested by the Lender, the Borrower shall issue to the Lender the Conversion Shares not in dispute in accordance with the terms hereof.

(iv) Record Holder . The person or persons entitled to receive the Conversion Shares issuable upon a conversion of this Note shall be treated for all purposes as the legal and record holder or holders of such shares of Common Stock upon delivery by the Lender of the Conversion Notice, or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section  2(c)(iii) , the first Business Day after the resolution of such bona fide dispute.

(v) Borrower’s Failure to Timely Convert .

6

(A) Cash Damages . 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, provided the Unrestricted Condition is satisfied), then, in addition to all other available remedies that the Lender may 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 such 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 such Lender (in addition to all other available remedies that the Lender may otherwise have), 110% of the amount by which (A) such Lender’s total purchase price (including brokerage commissions, if any) for such Buy-In Shares exceeds (B) the net proceeds received by such 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 specified by the Lender in the Conversion Notice.

(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 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; provided , that the voiding of the Lender’s 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 may

7

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.

(d) Limitations on Conversions .

(i) Beneficial Ownership . 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 conversion of this Note 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.

(ii) Conversion Issuance Limit . Notwithstanding anything to the contrary contained herein, the Borrower shall not issue any shares of Common Stock upon conversion of this Note (including pursuant to Section  2(c)(v)(A) hereof) to the extent that the issuance of such shares of Common Stock together with any previous issuances of shares of Common Stock under this Note would exceed the Conversion Issuance Limit, and Section 2.5(c)(v) shall not apply in respect to any excess amount.

(iii) Other Applicable Limitations on Conversion of the Note . Notwithstanding anything to the contrary herein, this Note shall not be convertible, and the Borrower shall not issue shares of Common Stock upon conversion of this Note (a) at any time after the First Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the First Amortization Date, would exceed the First Amortization Cap, or (b)  at any time after the Second Amortization Date, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares of Common Stock previously issued to Lender upon conversion of this Note after the Second Amortization

8

Date, would exceed the Second Amortization Cap, or (c) during any Monthly Conversion Cap Period, to the extent that the number of shares of Common Stock that would otherwise be issuable to Lender upon such conversion, together with all shares previously issued to Lender upon conversion of this Note during the such Monthly Conversion Cap Period, would exceed the Monthly Conversion Cap. For the avoidance of doubt, if the number of shares of Common Stock to be issued as set forth in an Conversion Notice transmitted by the Lender to the Borrower would otherwise require the Borrower to issue a number of shares in excess of the Conversion Issuance Limit, the First Amortization Cap (if after the First Amortization Date), the Second Amortization Cap (if after the Second Amortization Date) or the Monthly Share Cap, the Borrower shall issue to the Lender in accordance herewith the maximum number of shares of Common Stock issuable without exceeding any such applicable limitation, and Section 2.5(c)(v) shall not apply to any excess amount.

3. Voting Rights . Except as required by law, the Lender shall have no voting rights with respect to any of the Conversion Shares until the Conversion Date relating to the conversion of this Note upon which such Conversion Shares are issuable (or in the case of Conversion Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in compliance with the time periods and other provisions of, the dispute resolution provisions of Section  2(c)(iii) , the first Business Day after the resolution of such bona fide dispute).

4. Amendment; Waiver . The provisions of this Note may only be waived or amended, restated, supplemented or otherwise modified in accordance with the Facility Agreement.

5. Specific Shall Not Limit General; Construction . No specific provision contained in this Note shall limit or modify any more general provision contained herein. This Note shall be deemed to be jointly drafted by the Borrower and all Lenders pursuant to the Facility Agreement and shall not be construed against any Person as the drafter hereof.

6. Failure or Indulgence Not Waiver . No delay or omission by the Lender in exercising any power or right hereunder shall impair such right or power or be construed to be a waiver of any default, nor shall any single or partial exercise of any power or right hereunder preclude the full exercise thereof or the exercise of any other power or right. No renewal or extension of this Note or the Facility Agreement, no delay in the enforcement of payment under this Note or the Facility Agreement, and no delay or omission in exercising any right or power under this Note or the Facility Agreement shall affect the liability of the Borrower or any endorser of this Note.

7. Notices . Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be given in accordance with Section 6.1 of the Facility Agreement.

8. Restrictions on Transfer .

(b) Assignment .

The Borrower shall effect the assignment within three (3) business days, and shall deliver to the assignee(s) designated by the Lender a Note or Notes of like tenor and terms for the appropriate Principal amount. This Note and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns of the Lender. The provisions of this Note are intended to be for the benefit of all Lenders from time to time of this Note, and shall be enforceable by any such Lender. This Note is not (and any rights or obligations hereunder are not) not assignable or transferable by the Borrower under any circumstance and any such prohibited assignment or transfer is absolutely void ab initio .

9. Payment of Collection, Enforcement and Other Costs . If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding; or (b) an attorney is retained to represent the Lender in any bankruptcy, reorganization, receivership of the Borrower or other proceedings affecting Borrower creditors’ rights and involving a claim under this Note, then the Borrower shall pay the costs incurred by the Lender for such collection, enforcement or action, including reasonable attorneys’ fees and disbursements. Subject to the terms of the Facility Agreement, all payments and issuances of shares of Common Stock hereunder will be free and clear of, and without deduction or withholding for, any present or future taxes. The Borrower shall pay all and any costs (administrative or otherwise) imposed by the Borrower’s banks, clearing houses, or any other financial institution, in connection with making any payments and issuing any shares of Common Stock hereunder. The Borrower shall pay all costs and expenses (including attorney’s fees) of the Lender incurred in connection with this Note in accordance with Section 6.3 of the Facility Agreement.

10. Waiver of Notice . Other than those notices required to be provided by the Lender to the Borrower under the terms of the Facility Agreement, the Borrower and every endorser of this Note, or the obligations represented hereby, expressly waives diligence, presentment, protest, demand, notice of dishonor, non-payment or default, and notice of any kind with respect to this Note and the Facility Agreement or the performance of the obligations under this Note and/or the Facility Agreement.

12. Additional Interpretative Matters . Unless the context otherwise requires, (a) all references to Sections or Exhibits are to Sections or Exhibits contained in or attached to this Note, (b) each accounting term not otherwise defined in this Note has the meaning assigned to it in accordance with GAAP, (c) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter and (d) the use of the word “including” in this Note shall be by way of example rather than limitation. If a Stock Event occurs during any period over which an average price is being determined, then an appropriate adjustment will be made to such average to reflect such Stock Event.

13. Signatures . In the event that any signature to this Note or any amendment hereto is delivered by electronic mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such “.pdf” signature page were an original thereof.

At the request of any party, each other party shall promptly re-execute an original form of this Note or any amendment hereto and deliver the same to the other party. No party hereto shall raise the use of electronic mail delivery of a “.pdf” format data file to deliver a signature to this Note or any amendment hereto or the fact that such signature was transmitted or communicated through the use of electronic mail delivery of a “.pdf” format data file as a defense to the formation or enforceability of a contract, and each party hereto forever waives any such defense.
