For purposes of this Article VI, “ Registrable Securities ” means all shares of Common Stock issuable pursuant to (a) the conversion of the Notes or any other convertible promissory notes issued by the Company in a form substantially similar to Exhibit A on or before January 31, 2019 (collectively, “ Series Notes ”) and (b) the exercise of the Warrants or any other warrants to purchase Common Stock, in each case issued by the Company in connection with the issuance of any Series Notes.

6.2      Demand Registration .

(a)     Prior to the earlier of (a) the date on which all Registrable Securities may be sold without registration and without restriction or in accordance with Rule 144 in a single transaction and (b) the three-year anniversary of the Effective Date, holders of at least 75% of the Registrable Securities then outstanding may request, in writing, registration under the Securities Act of all or any portion of the Registrable Securities that equals or exceeds 75% of the then outstanding Registrable Securities pursuant to a Registration Statement. The Company, in its sole discretion, may prepare a registration statement on a Form S-1 or any equivalent or successor form thereto (a “ Long-Form Registration ”), or on Form S-3 or any equivalent or successor form thereto (a “ Short-Form Registration ” and, collectively with any Long-Form Registration, a “ Demand Registration ”). Such request for a Demand Registration must specify the number of Registrable Securities requested to be included in the Demand Registration. Upon receipt of any such request, the Company will promptly (but in no event later than 20 days following receipt thereof) deliver notice of such request to all other holders of Registrable Securities who will then have 10 days from the date such notice is given to notify the Company in writing of their desire to be included in such registration. The Company will prepare and file with (or confidentially submit to) the SEC a Registration Statement covering all of the Registrable Securities that the holders thereof have requested to be included pursuant to such Demand Registration within 60 days after the date on which the initial request is given and will use its commercially reasonable efforts to cause such Registration Statement to be declared effective by the SEC as soon as practicable thereafter, subject to compliance with review by the SEC. The Company is not required seek effectiveness of a Demand Registration more than once for the holders of Registrable Securities as a group; provided, that a Registration Statement will not count as a Demand Registration requested under this Section 6.2(a) unless and until it has become effective.

(b)     The Company will select the investment banking firm or firms to act as the managing underwriter or underwriters in connection with the Demand Registration; provided, that such selection will be subject to the consent of the Investors holding at least a majority of the Registrable Securities initiating the Demand Registration, which consent shall not be unreasonably withheld or delayed. The Company will bear all fees and expenses attendant to the registration of the Registrable Securities requested to be included in the Demand Registration pursuant to this Section 6.1, but the Investors will pay any and all underwriting commissions and the expenses of any legal counsel selected by the Investors to represent them in connection with the sale of the Registrable Securities.

(c)     The Company is not obligated to seek effectiveness of any Long-Form Registration within 90 days after the effective date of a previous Registration Statement or filing of a supplement for the purpose of effecting an offering pursuant to Rule 415 under the Securities Act (a “ Shelf Takedown ”). The Company may postpone for up to 90 days the filing or effectiveness of a Registration Statement or Shelf Takedown for a Demand Registration if the Board determines in its reasonable good faith judgment that such Demand Registration would (i) materially interfere with a significant acquisition, corporate organization, financing, securities offering or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act; provided, that in such event the holders of at all of the Registrable Securities initiating such Demand Registration will be entitled to withdraw such request and, if such request for a Demand Registration is withdrawn, such Demand Registration will not count as the permitted Demand Registration hereunder.

(d)     If the managing underwriter of the requested Demand Registration advises the Company, in writing, that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in the Demand Registration, including all Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common Stock that can be sold in such underwritten offering and/or the number of shares of Common Stock proposed to be included in such Demand Registration would adversely affect the price per share of the Common Stock proposed to be sold in such underwritten offering, the Company will include in such Demand Registration (i) first, the shares of Common Stock that the holders of Registrable Securities propose to sell, and (ii) second, the shares of Common Stock proposed to be included therein by any other Persons (including shares of Common Stock to be sold for the account of the Company and/or other holders of Common Stock) allocated among such Persons in such manner as they may agree. If the managing underwriter determines that less than all of the Registrable Securities proposed to be sold can be included in such offering, then the Registrable Securities that are included in such offering will be allocated pro rata among the respective holders thereof on the basis of the number of Registrable Securities requested to be included in the Demand Registration by each such holder.

6.3       Piggy b ack Registration .

(a)     Prior to the three-year anniversary of the Effective Date, whenever the Company proposes to register the offer and sale of any shares of its Common Stock under the Securities Act (other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to employees or directors of the Company pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), or (iii) in connection with any dividend or distribution reinvestment or similar plan), whether for its own account or for the account of one or more stockholders of the Company and the form of Registration Statement (a “ Piggyback Registration Statement ”) to be used may be used for any registration of Registrable Securities (a “ Piggyback Registration ”), the Company shall give prompt written notice (in any event no later than 15 days prior to the filing of such Registration Statement) to the holders of Registrable Securities of its intention seek such a registration and, subject to Section 6.3(b) and 6.3(c), shall include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion from the holders of Registrable Securities within 10 days after the Company’s notice has been given to each such holder. The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion. A Piggyback Registration shall not be considered a Demand Registration for purposes of Section 6.1. If any Piggyback Registration Statement pursuant to which holders of Registrable Securities have registered the offer and sale of Registrable Securities is a Registration Statement on Form S-3 or the then appropriate form for an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor rule thereto (a “ Piggyback Shelf Registration Statement ”), such holder(s) shall have the right, but not the obligation, to be notified of and to participate in any offering under such Piggyback Shelf Registration Statement (a “ Piggyback Shelf Takedown ”).

(b)     If a Piggyback Registration or Piggyback Shelf Takedown is initiated as a primary underwritten offering on behalf of the Company and the managing underwriter advises the Company and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include Registrable Securities in such Piggyback Registration or Piggyback Shelf Takedown) in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in such registration or takedown, including all Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or that the number of shares of Common Stock proposed to be included in any such registration or takedown would adversely affect the price per share of the Common Stock to be sold in such offering, the Company shall include in such registration or takedown (i) first, the shares of Common Stock that the Company proposes to sell; (ii) second, the shares of Common Stock requested to be included therein by holders of Registrable Securities, allocated pro rata among all such holders on the basis of the number of Registrable Securities owned by each such holder or in such manner as they may otherwise agree; and (iii) third, the shares of Common Stock requested to be included therein by holders of Common Stock other than holders of Registrable Securities, allocated among such holders in such manner as they may agree.

(c)     If a Piggyback Registration or Piggyback Shelf Takedown is initiated as an underwritten offering on behalf of a holder of Common Stock other than Registrable Securities, and the managing underwriter advises the Company in writing that in its reasonable and good faith opinion the number of shares of Common Stock proposed to be included in such registration or takedown, including all Registrable Securities and all other shares of Common Stock proposed to be included in such underwritten offering, exceeds the number of shares of Common Stock which can be sold in such offering and/or that the number of shares of Common Stock proposed to be included in any such registration or takedown would adversely affect the price per share of the Common Stock to be sold in such offering, the Company shall include in such registration or takedown (i) first, the shares of Common Stock requested to be included therein by the holder(s) requesting such registration or takedown and by the holders of Registrable Securities, allocated pro rata among all such holders on the basis of the number of shares of Common Stock other than the Registrable Securities (on a fully diluted, as converted basis) and the number of Registrable Securities, as applicable, owned by all such holders or in such manner as they may otherwise agree; and (ii) second, the shares of Common Stock requested to be included therein by other holders of Common Stock, allocated among such holders in such manner as they may agree.

(d)     If any Piggyback Registration or Piggyback Shelf Takedown is initiated as a primary underwritten offering on behalf of the Company, the Company shall select the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering.

6.4      Continued Effectiveness of Registration Statement . The Company will use commercially reasonable efforts to keep any Registration Statement covering the Registrable Securities effective at all times during the period from the Effective Date through the three-year anniversary of the Effective Date (the “ Registration Period ”). In the event that the number of shares available under a Registration Statement filed pursuant to this Agreement is insufficient to cover all of the Registrable Securities requested to be included in the Demand Registration, the Company will (if permitted) amend the Registration Statement or file a new Registration Statement, so as to cover all of the Registrable Securities originally requested to be included in the Demand Registration. The Company will file such amendment or new Registration Statement as soon as practicable, but in no event later than 30 business days after the necessity therefor arises (based upon the market price of the Common Stock and other relevant factors on which the Company reasonably elects to rely). The Company will use commercially reasonable efforts to cause such amendment or new Registration Statement to declare effective by the SEC as soon as practicable thereafter, subject to compliance with review by the SEC.

6.5      Furnishing Documentation . The Company will furnish to each Investor whose Registrable Securities are included in a Registration Statement, promptly after each document is prepared and publicly distributed, filed with the SEC or received by the Company, one copy of any Registration Statement filed pursuant to this Agreement and any amendments thereto, each preliminary prospectus and final prospectus and each amendment or supplement thereto. Any such documents filed with the SEC and publicly available pursuant to the SEC’s Electronic Data Gathering, Analysis and Retrieval (EDGAR) or any replacement system will be deemed furnished to each Investor in satisfaction of this Section 6.5.

6.6      Additional Obligations . The Company will use commercially reasonable efforts to (a) register and qualify the Registrable Securities covered by a Registration Statement under such other securities or blue sky laws of such jurisdictions as each Investor who holds Registrable Securities being offered reasonably requests, (b) prepare and file in those jurisdictions any amendments (including post effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain their effectiveness during the Registration Period, (c) take any other actions necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (d) take any other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions. Notwithstanding the foregoing, the Company is not required, in connection with such obligations, to (i) register, license or qualify to do business in any jurisdiction, (ii) subject itself to general taxation in any such jurisdiction, (iii) file a general consent to service of process in any such jurisdiction, (iv) provide any undertakings that cause material expense or burden to the Company or holders of greater than 5% of its outstanding securities, or (v) make any change in its charter or bylaws, which in each case the board of directors of the Company, in its sole discretion, determines to be contrary to the best interests of the Company and its shareholders.

6.7       Suspension of Registration .

(a)     The Company will notify each Investor, which notice (including the fact of such notice and the content thereof) each Investor agrees to treat in confidence and not to disclose, who holds Registrable Securities being sold pursuant to a Registration Statement of the happening of any event of which the Company has knowledge as a result of which the prospectus included in the Registration Statement as then in effect includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The Company will make such notification as promptly as practicable after the Company becomes aware of the event, will promptly prepare a supplement or amendment to the Registration Statement to correct such untrue statement or omission. The Company will use commercially reasonable efforts to keep the length of any such suspension to as short a period as is practicable given the then existing circumstances and to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement and, if such an order is issued, will use commercially reasonable efforts to obtain the withdrawal of such order at the earliest possible time.

(b)      Information . The Company will make generally available to its security holders as soon as practicable, but not later than 90 days after the close of the period covered thereby, an earnings statement (in a form complying with the provisions of Rule 158 under the Securities Act) covering a 12-month period beginning not later than the first day of the Company’s fiscal quarter next following the effective date of the Registration Statement.

6.8      Listing . The Company will use commercially reasonable efforts to cause all of the Registrable Securities covered by the Registration Statement to be (i) eligible for quotation on the over-the-counter markets or (ii) listed on each national securities exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such national securities exchange.

6.9      Transfer Agent; Registrar . The Company will provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of the Registration Statement.

6.10   Securities Laws Compliance . The Company will comply with all applicable laws related to any Registration Statement relating to the sale of Registrable Securities and to offering and sale of securities and with all applicable rules and regulations of governmental authorities in connection therewith (including, without limitation, the Securities Act, the Exchange Act and the rules and regulations promulgated by the SEC).

6.11    Investor Information . As a condition to the obligations of the Company to complete any registration pursuant to this Agreement with respect to the Registrable Securities of each Investor, such Investor will furnish to the Company such information regarding itself, the Registrable Securities held by it, and such other information as is reasonably required by the Company to register the Registrable Securities. At least 15 business days prior to the first anticipated filing date of a Registration Statement for any registration under this Agreement, the Company will notify each Investor requesting inclusion of their Registrable Securities of the information the Company requires from that Investor if the Investor elects to have any of its Registrable Securities included in the Registration Statement. If, within three business days prior to the filing date, the Company has not received the requested information from an Investor, then the Company may file the Registration Statement without including Registrable Securities of that Investor.

6.12    Further Assurances . The Company will comply with all applicable laws related to any Registration Statement relating to the sale of Registrable Securities and to offering and sale of securities and with all applicable rules and regulations of governmental authorities in connection therewith (including, without limitation, the Securities Act, the Exchange Act and the rules and regulations promulgated by the SEC).

6.13    Suspension of Sales . Upon receipt of any notice from the Company of the happening of any event of the kind described in Section 6.7, sales of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities will be discontinued unless and until an amended prospectus contemplated by Section 6.7 is available or the suspension of sales under Section 6.7 has terminated.

6.14    Conflicting Instructions . A person or entity is deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more persons or entities with respect to the same Registrable Securities, the Company will act upon the basis of instructions, notice or election received from the registered owner of such Registrable Securities.

6.15    Indemnification for Registration . In the event that any Registrable Securities are included in a Registration Statement under this Agreement:

(a)     To the extent permitted by law, the Company will indemnify and hold harmless each Investor that holds such Registrable Securities, and any person who controls such Investor within the meaning of Section 15 of the Exchange Act (each, an “ Investor Indemnified Person ”) against any losses, claims, damages, liabilities (joint or several), or reasonable expenses (including all reasonable attorneys’ fees) (collectively, and together with actions, proceedings or inquiries by any regulatory or self-regulatory organization, whether commenced or threatened in respect thereof, “ Claims ”) to which any of them become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Claims arise out of or are based upon any of the following statements, omissions or violations in a Registration Statement filed pursuant to this Agreement, any post-effective amendment thereof or any prospectus included therein (collectively, “ Violations ”): (a) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any post-effective amendment thereof or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (b) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any other law, including without limitation any state securities law or any rule or regulation thereunder. Subject to the restrictions set forth in Section 6.15(c) with respect to the number of legal counsel, the Company will reimburse the Investor Indemnified Person, periodically as such expenses are incurred, for any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6.15(a) does not apply to Claims arising out of or based upon a Violation that occurs in reliance upon and in conformity with information furnished to the Company by an Investor Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to this Agreement; and (ii) does not apply to amounts paid in settlement of any Claim if such settlement is made without the prior written consent of the Company, which consent will not be unreasonably withheld. This indemnity obligation will remain in full force and effect regardless of any investigation made by or on behalf of the Investor Indemnified Persons and will survive the transfer of the Registrable Securities by the Investors under this Agreement.

(b)     In connection with any Registration Statement in which an Investor is participating, each such Investor will indemnify and hold harmless, to the same extent and in the same manner set forth in Section 6.15(a), the Company, each of its directors, each of its officers who signs the Registration Statement, each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, and any other shareholder selling securities pursuant to the Registration Statement and any of its directors and officers and any person who controls such shareholder within the meaning of Section 15 of the Securities Act (each an “ Other Indemnified Person ”) against any Claim to which any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement, post-effective amendment thereof or any prospectus included therein. Subject to the restrictions set forth in Section 6.15(c), such Investor will periodically reimburse the Company and each such Other Indemnified Person, any legal or other expenses (promptly as such expenses are incurred) reasonably incurred by them in connection with investigating or defending any such Claim. However, the indemnity agreement contained in this Section 6.15(b) does not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent will not be unreasonably withheld, and no Investor will be liable under this Agreement (including this Section 6.15(b)) for the amount of any Claim that exceeds the net proceeds actually received by such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. This indemnity will remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party and will survive the transfer of the Registrable Securities by the Investors under this Agreement.

(c)     Promptly after receipt by an Investor Indemnified Person or Other Indemnified Person (each, an “ Indemnified Person ”) under this Section 6.15 of notice of the commencement of any action (including any governmental action), such Indemnified Person will, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6.15, deliver to the indemnifying party a written notice of the commencement thereof. The indemnifying party may participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly given notice, assume control of the defense thereof with counsel mutually satisfactory to the indemnifying parties, provided that such selection will be subject to the consent of the Indemnified Person, which consent shall not be unreasonably withheld or delayed. In that case, the indemnifying party will diligently pursue such defense. If, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person and the indemnifying party would be inappropriate due to actual or potential conflicts of interest between the indemnifying party and the Indemnified Person and any other party represented by such counsel in such proceeding or the actual or potential defendants in, or targets of, any such action including the Indemnified Person, and such Indemnified Person reasonably determines that there may be legal defenses available to such Indemnified Person that are different from or in addition to those available to the indemnifying party, then the Indemnified Person is entitled to assume such defense and may retain its own counsel, with the reasonable fees and expenses to be paid by the indemnifying party (subject to the restrictions on settlement under Section 6.15(a) or Section 6.15(b), as applicable). The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action does not relieve an indemnifying party of any liability to an Indemnified Person under this Section 6.15, except to the extent that the indemnifying party is prejudiced in its ability to defend such action. Each Indemnified Person will cooperate fully with the indemnifying party to furnish such information regarding itself or the claim in question as an Indemnifying Person may reasonably request or as may be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

6.16      Contribution .     To the extent that any indemnification provided for under Section 6.15 is prohibited or limited by law, the indemnifying party will make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6.15 to the fullest extent permitted by law. However, (a) no contribution will be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 6.15(b), (b) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation, and (c) contribution (together with any indemnification or other obligations under this Agreement) by any seller of Registrable Securities will be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities.

6.17      Lock-up Agreement . Each holder of Registrable Securities agrees that in connection with any registered offering of the Common Stock or other equity securities of the Company, and upon the request of the managing underwriter in such offering, such holder shall not, without the prior written consent of such managing underwriter, during the period commencing on the effective date of such registration and ending on the date specified by such managing underwriter (such period not to exceed 180 days), (a) offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, hedge the beneficial ownership of or otherwise dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into, exercisable for or exchangeable for shares of Common Stock held immediately before the effectiveness of the Registration Statement for such offering/(whether such shares or any such securities are then owned by the holder or are thereafter acquired), or (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing provisions of this Section 6.17 shall not apply to sales of Registrable Securities to be included in such offering pursuant to Section 6.1 or 6.3, and shall be applicable to the holders of Registrable Securities only if all officers and directors of the Company and all stockholders owning more than 10% of the Company’s outstanding Common Stock are subject to the same restrictions. Each holder of Registrable Securities agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the managing underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. Notwithstanding anything to the contrary contained in this Section 6.17, each holder of Registrable Securities shall be released, pro rata, from any lock-up agreement entered into pursuant to this Section 6.17 in the event and to the extent that the managing underwriter or the Company permit any discretionary waiver or termination of the restrictions of any lock-up agreement pertaining to any officer, director or holder of greater than 10% of the outstanding Common Stock.

Accrual of interest will commence on the date of this Note, will continue until this Note is fully paid, and will be payable in a single installment at maturity as set forth below. The interest rate will be computed on the basis of the actual number of days elapsed in a 365-day year.

All payments of interest and principal will be made in lawful money of the United States of America and will be made pro rata among all holders of Series Notes, without any deduction by way of set-off, counterclaim, or otherwise. All payments will be applied first to interest and thereafter to principal. All payments will be made to the Investor at the address set forth in the Agreement or at such other address as is provided in writing to the Company.

3.        Ranking . This Note represents an unsecured obligation of the Company. It is subordinated in right of payment to the prior payment in full of any Senior Indebtedness (defined below). Notwithstanding the foregoing, this Note ranks equally with all other Notes with respect to right of payment and priority. “ Senior Indebtedness ” means, unless expressly subordinated to or made on a parity with the amounts due under the Series Notes, all amounts due in connection with (a) indebtedness of the Company to banks or other lending institutions regularly engaged in the business of lending money (including venture capital, investment banking or similar institutions and their affiliates that sometimes engage in lending activities but are primarily engaged in investments in equity securities) and (b) any indebtedness or any issued in exchange for such Senior Indebtedness by a guarantor.

(b)     No Fractional Shares. The number of shares and/or units of Company securities issuable pursuant to this Section 5 will be rounded down to the nearest whole share.

(c)     The “ Conversion Price ” will initially equal $3.50, but may be adjusted prior to conversion as follows:

(i)     If the Company subdivides its outstanding shares of Common Stock into a greater number of shares, then the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced.

(ii)     If the Company combines its outstanding shares of Common Stock into a smaller number of shares, then the Conversion Price in effect immediately prior to such combination will be proportionately increased.

(iii)     If the Company issues shares of Common Stock or units consisting of shares of Common Stock for all cash consideration or upon the conversion of indebtedness for less than $3.50 per share of Common Stock (excluding any Qualified Financing that results in conversion of the Note), then the Conversion Price will be reduced to the per share price paid by investors in such issuance of Common Stock.

6.        Actions on Conversion . At such time as this Note is converted into Company securities, the rights of the Investor under this Note will cease, and such person will be treated for all purposes as the record holder of the securities issuable upon conversion.

7.        Series Notes . This Note is one of a series of convertible promissory notes of like tenor issued by the Company between December 1, 2018 and January 31, 2019 (collectively, the “ Series Notes ”). When actions are specified herein as happening upon the decision of holders of a majority in principal amount of the Series Notes, such action shall be evidenced by a writing executed by such holders and delivered to all holders of Series Notes and shall be the act of and binding on all holders of Series Notes.

8.         Restriction on Transfer of the Note . Any sale or transfer of this Note must comply with the requirements contained in the Agreement.

10.      No Rights or Liabilities as Holder of Equity Interests . This Note does not of itself entitle the Investor to any voting rights or other rights as a holder of equity interests in the Company. In the absence of conversion of this Note, no provisions of this Note, and no enumeration herein of the rights or privileges of the Investor, shall cause the Investor to be a holder of equity interests in the Company for any purpose.

The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable.

9.       Certain Adjustments . In order to mitigate dilution of the purchase rights granted under this Warrant, the Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as provided in this Section 9 (in each case after taking into consideration any prior adjustments pursuant to this Section 9).

(a)     Adjustment to Exercise Price Upon Issuance of Derivative Securities . Except as provided in Section 9(b) and except in the case of an event described in either Section 9(d) or Section 9(e), if the Company shall, at any time or from time to time after the Original Issue Date and before June 30, 2019, issue or sell any securities exercisable for, or convertible into, shares of Common Stock (collectively “ Purchase Rights ”) based on a price per share less than the Exercise Price in effect immediately prior to such issuance or sale, then immediately upon such issuance or sale, the Exercise Price in effect immediately prior to such issuance or sale shall be reduced (and in no event increased) to an Exercise Price equal to the price per share reflected by such newly issued or sold Purchase Rights.

(b)     Exceptions t o Adjustment Upon Issuance of Purchase Rights . Anything herein to the contrary notwithstanding, there shall be no adjustment to the Exercise Price or the number of Warrant Shares issuable upon exercise of this Warrant with respect to any issuance or sale by the Company after the Original Issue Date (each, an “ Excluded Issuance ”) of Purchase Rights: (a) in the form of equity awards granted to directors, officers, employees, or consultants of the Company in connection with their service as directors of the Company, their employment by the Company or their retention as consultants by the Company, in each case authorized by the Board and issued pursuant to an equity incentive plan approved by the stockholders of the Company (including all such equity awards outstanding prior to the Original Issue Date); (b) issued (i) to persons in connection with a joint venture, strategic alliance or other commercial relationship with such person (including persons that are customers, suppliers and strategic partners of the Company) relating to the operation of the Company’s business and not for the primary purpose of raising equity capital, (ii) in connection with a transaction in which the Company, directly or indirectly, acquires another business or its tangible or intangible assets, or (iii) to lenders as equity kickers in connection with debt financings of the Company, in each case where such transactions have been approved by the Board; (c)  issued in an offering for cash for the account of the Company that is underwritten on a firm commitment basis and is registered with the Securities and Exchange Commission under the Securities Act of 1933, as amended; or (d) issued to the lessor or vendor in any office lease or equipment lease or similar equipment financing transaction in which the Company obtains the use of such office space or equipment for its business.

(c)     Treatment of Expired or Terminated Purchase Rights . Upon the expiration or termination of any unexercised Purchase Right (or portion thereof) for which any adjustment (either upon its original issuance or upon a revision of its terms) was made pursuant to this Section 9 (including without limitation upon the redemption or purchase for consideration of all or any portion of such Purchase Right by the Company), the Exercise Price then in effect hereunder shall forthwith be changed pursuant to the provisions of this Section 9 to the Exercise Price that would have been in effect at the time of such expiration or termination had such unexercised Purchase Right (or portion thereof), to the extent outstanding immediately prior to such expiration or termination, never been issued.

(d)     Fundamental Transactions . If, at any time while this Warrant is outstanding, there is a Fundamental Transaction, then the Holder shall have the right thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “ Alternate Consideration ”). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. At the Holder’s option and request, any successor to the Company or surviving entity in such Fundamental Transaction shall, either (1) issue to the Holder a new warrant substantially in the form of this Warrant and consistent with the foregoing provisions and evidencing the Holder’s right to purchase the Alternate Consideration for the aggregate Exercise Price upon exercise thereof, or (2) purchase the Warrant from the Holder for a purchase price, payable in cash within five Trading Days after such request (or, if later, on the effective date of the Fundamental Transaction), equal to the Black Scholes value of the remaining unexercised portion of this Warrant on the date of such request. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (b) and insuring that the Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(e)     Stock Dividends and Splits . If, at any time while this Warrant is outstanding, the Company (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be adjusted to equal the product obtained by multiplying the then-current Exercise Price by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

(f)     Calculations . All calculations under this Section 9 shall be made to the nearest cent or the nearest 1/100 ^th of a share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

(g)     Notice of Adjustments . Upon the occurrence of each adjustment pursuant to this Section 9, the Company, at its expense will promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s Transfer Agent.

10.      Payment of Exercise Price . The Holder may pay the Exercise Price in only in the form of immediately available funds.

11.      No Fractional Shares . No fractional shares of Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares which would, otherwise be issuable, the Company shall pay cash equal to the product of such fraction multiplied by the Closing Price of one Warrant Share on the date of exercise.

12.      Notices . Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice) shall be in writing and shall be deemed given and effective if provided pursuant to the Purchase Agreement. In case any time: (1) the Company shall declare any cash dividend on its capital stock; (2) the Company shall pay any dividend payable in stock upon its capital stock or make any distribution to the holders of its capital stock; (3) the Company shall offer for subscription pro rata to the holders of its capital stock any additional shares of stock of any class or other rights; (4) there shall be any capital reorganization, or reclassification of the capital stock of the Company, or consolidation or merger of the Company with, or sale of all or substantially all of its assets to, another corporation; or (5) there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company; then, in any one or more of said cases, the Company shall give prompt written notice to the Holder. Such notice shall also specify the date as of which the holders of capital stock of record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their capital stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding up, or conversion or redemption, as the case may be. Such written notice shall be given at least 20 days prior to the action in question and not less than 20 days prior to the record date or the date on which the Company’s transfer books are closed in respect thereto.

13.      Registration Rights . The Holder is entitled to the registration rights set forth in Article VI of the Purchase Agreement.

14.      Miscellaneous .

(a)     This Warrant shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns. Subject to the preceding sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable right, remedy or cause of action under this Warrant. This Warrant may be amended only in writing signed by the Company and the Holder and their successors and assigns.

(b)     All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be governed by and construed and enforced in accordance with the internal laws of the State of Delaware, without regard to the principles of conflicts of law thereof.

(c)     The headings herein are for convenience only, do not constitute a part of this Warrant and shall not be deemed to limit or affect any of the provisions hereof.
