Section 2. Exercise.

a) Exercise of Warrants. Exercise of the purchase rights for Warrant Shares represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed notice of exercise in the form annexed hereto as Exhibit A (a “Notice of Exercise”), which may be delivered in a .PDF format via electronic mail pursuant to the notice provisions set forth in the Purchase Agreement. Within one (1) Trading Day of the date said Notice of Exercise is delivered to the Company (or within two (2) Trading Days of the date said Notice of Exercise is delivered to the Company if the Notice of Exercise is received after 12 p.m. EST on such day), the Company shall have received payment of the aggregate Exercise Price of the Warrant Shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank, unless such exercise is made pursuant to the cashless exercise procedure specified in Section 2(c) below (if available). No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required. The Company shall be entitled to conclusively assume the genuineness of any signature on any Notice of Exercise delivered to the Company pursuant to this Section 2(a), the legal capacity and competency of all natural persons signing any Notice of Exercise so delivered, the authenticity of any Notice of Exercise so delivered, the conformity to an authentic original of any Notice of Exercise so delivered as certified, authenticated, conformed, photostatic, facsimile, or electronic and the authenticity of the original of such Notice of Exercise. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases, and the Company shall be entitled to conclusively assume that its records of the number of Warrant Shares purchased and the date of such purchases are accurate, absent actual notice to the contrary. The Company shall deliver any objection to any Notice of Exercise within two (2) Business Days of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

b) Number of Warrant Shares. Subject to the terms and conditions set forth herein, the Holder shall have the right to purchase from the Company a number of Warrant Shares equal to (i) 10% multiplied by $[____________]¹, (ii) divided by the Exercise Price (as defined below), less the Exercise Value of all partial exercises of this Warrant in accordance with Section 2(a) prior to the Initial Exercise Date.

^1]Note to Form: Such amount to equal the value of the triggering purchase under the purchase agreement.

c) Exercise Price. The exercise price per Warrant Share shall [_____________]², subject to adjustment hereunder (the “Exercise Price”).

d) Cashless Exercise. If at any time there is no effective Registration Statement registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = the Market Price;

(B) = the Exercise Price of this Warrant, as adjusted hereunder; and

(X) = the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

Assuming (i) the Holder is not an Affiliate of the Company, and (ii) all of the applicable conditions of Rule 144 promulgated under the Securities Act of 1933, as amended (the “Securities Act”) with respect to Holder and the Warrant Shares are met in the case of such a cashless exercise, the Company agrees that the Company will use its best efforts to cause the removal of the legend from such Warrant Shares (including by delivering an opinion of the Company’s counsel to the Company’s transfer agent at its own expense to ensure the foregoing), and the Company agrees that the Holder is under no obligation to sell the Warrant Shares issuable upon the exercise of the Warrant prior to removing the legend. The Company expressly acknowledges that Rule 144(d)(3)(ii), as currently in effect, provides that Warrant Shares issued solely upon a cashless exercise shall be deemed to have been acquired at the same time as the Warrant. The Company agrees not to take any position contrary to this Section 2(c).

e) Mechanics of Exercise.

i. Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Company’s transfer agent (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder pursuant to Rule 144, and otherwise as a book-entry statement evidencing that the applicable Warrant Shares have been issued to the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the date that is one (1) Trading Day after the later of (A) the delivery to the Company of the Notice of Exercise provided that such Notice of Exercise is received by 12 p.m. EST and the Trading Day after Notice of Exercise for any Notice of Exercise received after 12 p.m. EST, and (B) the Company’s receipt of payment of the aggregate Exercise Price of the Warrant Shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank, unless such exercise is made pursuant to the cashless exercise procedure specified in Section 2(d) (such date, the “Warrant Shares Delivery Date”). The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(e)(vi) prior to the issuance of such Warrant Shares, having been paid. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $5 per Trading Day (increasing to $10 per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable.

2 Note to Form: Such amount to equal 130% of the triggering purchase price under the purchase agreement.

ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

iii. Rescission Rights. If the Holder fails to make payment of the aggregate Exercise Price of the Warrant Shares pursuant to a Notice of Exercise within two (2) Trading Days of the date said Notice of Exercise is delivered to the Company (or within three (3) Trading Days of the date said Notice of Exercise is delivered to the Company if the Notice of Exercise is received after 12 p.m. EST on such day) by wire transfer or cashier’s check drawn on a United States bank, then the Company will have the right to rescind such exercise, unless such exercise is made pursuant to the cashless exercise procedure specified in Section 2(d). If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(e)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

iv. Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 2(e)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the 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 (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the 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 the Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

v. No Fractional Shares or Scrip. No fractional shares of Common Stock or scrip representing fractional shares of Common Stock shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

vi. Charges, Taxes, and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all fees charged by the Transfer Agent, including any fees assessed to the Transfer Agent by Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day processing of any Notice of Exercise and for same-day electronic delivery of the Warrant Shares.

vii. Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

f) Holder’s Exercise Limitations.

i. Subject to the last sentence of this Section 2(f), the Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, the Holder (together with the Holder’s Affiliates and any other Persons acting as a group together) would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its Affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Form 10-K, Proxy Statement, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, where such request indicates that it is being made pursuant to this Warrant, the Company shall within three (3) Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrants, by the Holder and its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. Upon delivery of a written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage as specified in such notice; provided that in no event shall such Maximum Percentage be increased to more than 19.99%; provided, further, that (i) any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Warrants. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(f) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section 2(f) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations set forth in this Section 2(f) shall not apply to exercises of this Warrant that occur prior to and expressly in connection with the Company’s consummation of a Fundamental Transaction. Notwithstanding anything to the contrary herein, Warrant Shares may not be issued pursuant to this Warrant and this Warrant shall not be exercisable for Warrant Shares, to the extent that the issuance of the Warrant or the issuance of Warrant Shares upon exercise thereof would be impermissible without stockholder approval pursuant to the rules of the Trading Market. The limitations contained in this paragraph shall apply to a successor holder of this Warrant.

ii. To the extent the exercise of any portion of this Warrant requires the Company to receive the approval of the Company’s stockholders pursuant to Trading Market, the Company shall not effect such exercise of this Warrant, and a Holder shall not have the right to exercise any such portion of this Warrant, pursuant to Section 2 or otherwise, until such approval has been received by the Company.

Section 3. Certain Adjustments.

a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person (excluding a merger effected solely to change the Company’s name), (ii) the Company (and all of its Subsidiaries, taken as a whole), directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires greater than 50% of the voting power of the outstanding common and preferred stock of the Company (each a “Fundamental Transaction”) then, the Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(b) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

c) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares of Common Stock, if any) issued and outstanding.

d) Notice to Holder.

i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3 (excluding Section 3(c)), the Company shall promptly mail or deliver via electronic mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights, or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

a) Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney.

All Warrants issued on transfers or exchanges shall be dated the Issuance Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

d) Transfer Restrictions. Subject to any limitations imposed by applicable law, this Warrant may be offered for sale, sold, transferred, or assigned without the consent of the Company.

e) Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

a) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 3(a).

b) Loss, Theft, Destruction, or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction, or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

d) Authorized Shares. The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant (the “Required Reserve Amount”). The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid, and nonassessable and free from all taxes, liens, and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

e) Transfer Agent Instructions. The Company covenants and agrees that it will, at all times during the period the Warrant is outstanding, maintain a duly qualified independent Transfer Agent. The Company represents and covenants that, within one (1) day from the Issuance Date, it will either (i) issue irrevocable instructions to its current Transfer Agent (and each Transfer Agent appointed thereafter) to issue certificates or book-entry statements, registered in the name of the Holder or its nominee, for the Warrant Shares in such amounts as specified from time to time by the Holder to the Company upon exercise of this Warrant in accordance with the terms thereof (the “Irrevocable Transfer Agent Instructions”), or (ii) appoint a new Transfer Agent, at which time the Company (a) shall provide a copy of its agreement with the new Transfer Agent to the Holder, and (b) issue Irrevocable Transfer Agent Instructions to the new Transfer Agent. Such Irrevocable Transfer Agent Instructions shall be in a form acceptable to the Holder and shall include a provision to irrevocably reserve the Required Reserve Amount. The Irrevocable Transfer Agent Instructions shall be signed by the Company’s Transfer Agent as of the date of the Issuance Date and by the Company. The Company warrants that, (i) no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5(e), and stop transfer instructions to give effect to Section 5(g) (prior to registration of the Warrant Shares under the Securities Act or the date on which the Warrant Shares may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold), will be given by the Company to its Transfer Agent and that the Warrant Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Warrant and the Purchase Agreement, (ii) it will not direct its Transfer Agent not to transfer or delay, impair, and/or hinder its Transfer Agent in transferring (or issuing)(electronically or in certificated form) any certificate or book-entry statement for Warrant Shares to be issued to the Holder upon exercise of or otherwise pursuant to this Warrant as and when required by this Warrant and the Purchase Agreement, and (iii) it will not fail to remove (or direct its Transfer Agent not to remove or impair, delay, and/or hinder its Transfer Agent from removing) any restrictive legend (or to withdraw any stop transfer instructions in respect thereof) on any certificate for any Warrant Shares issued to the Holder upon exercise of or otherwise pursuant to this Warrant as and when required by this Warrant and the Purchase Agreement. Nothing in this Section shall affect in any way the Holder’s obligations to comply with all applicable prospectus delivery requirements, if any, upon resale of the Warrant Shares. If a Holder provides the Company, at the cost of the Holder, with an opinion of counsel in form, substance, and scope customary for opinions in comparable transactions, to the effect that a public sale or transfer of such Warrant Shares may be made without registration under the Securities Act and such sale or transfer is effected, the Company shall permit the transfer, and, in the case of the Warrant Shares, promptly instruct its Transfer Agent to issue one or more certificates or book-entry statements, free from restrictive legend, in such name and in such denominations as specified by the Holder. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder, by vitiating the intent and purpose of the transactions contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5(e) may be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section, that the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach and requiring immediate transfer, without the necessity of showing economic loss and without any bond or other security being required.

f) Jurisdiction. All questions concerning the construction, validity, enforcement, and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

g) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

h) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers, or remedies, notwithstanding the fact that all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

i) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.

j) Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

k) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant, without the necessity of showing economic loss and without any bond or other security being required. The Company agrees that monetary damages may not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

l) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

m) Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

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

o) Headings. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the other Transaction Documents shall have the meanings ascribed to such terms on the Execution Date in such other Transaction Documents unless otherwise consented to in writing by the Holder.

p) Governing Law. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation, and performance of this Warrant shall be governed by, the internal laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Delaware. The Company hereby irrevocably waives personal service of process and consents to process being served in any such suit, action, or proceeding by mailing a copy thereof to the Company at the address set forth in the Purchase Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.

q) Jurisdiction and Venue. Each party hereby irrevocably submits that any dispute, controversy or claim arising out of or relating to this Warrant, shall be submitted to the exclusive jurisdiction of the Chancery Court of the State of Delaware and the United States District Court for the District of Delaware. Each party hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under the Purchase Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS WARRANT. The parties agree that all dispute resolution proceedings in accordance with this Section 5(q) may be conducted in a virtual setting.

r) Right to Participate in Future Offerings.

i. For a period of 12 months from the Execution Date, the Company shall not, and shall cause each of its subsidiaries not to, (x) contract with any party for the issuance of any indebtedness that includes an equity component or that is convertible into, exercisable into or exchangeable for equity securities of the Company or any of its subsidiaries or equity financing, or (y) issue any equity securities of the Company or any of its subsidiary or securities convertible, exchangeable or exercisable into or for equity securities of the Company or any of its subsidiaries (including any indebtedness that includes an equity component or that is convertible into, exercisable into or exchangeable for equity securities of the Company or any of its subsidiaries) (a “Future Offering”), except pursuant to Excluded Issuances (as defined below) and “at-the-market” offerings under Rule 415(a)(4) of the Securities Act (none of which shall be considered Future Offerings and to which the Holder Purchase Option (as defined below) shall not apply), unless it shall have first delivered to the Holder written notice (the “Future Offering Notice”) describing generally the proposed Future Offering and providing the Holder an option (the “Holder Purchase Option”) to purchase up to a number of securities to be issued in such Future Offering equal to the product (such product, the Holder’s “Allocation Portion”) of (A) a fraction, (1) the numerator of which is the sum of the number of shares of Common Stock acquired by the Holder under Purchase Notices and the number of Warrant Shares issued, and (2) the denominator of which is the number of shares of Common Stock issued and outstanding on the date of the Future Offering Notice, and (B) the total amount of securities to be issued in such Future Offering.

ii. The Company will give to the Holder the Future Offering Notice any proposed Future Offering before such issuance or sale may be consummated. The Future Offering Notice will set forth the Company’s bona fide intention to offer such Future Offering and the material terms and conditions of the proposed issuance or sale, including: (a) the number and description of securities proposed to be issued; (b) the proposed issuance date, which shall be at least two (2) calendar days from the date of the Future Offering Notice; and (c) the proposed purchase price per security and all other material terms of the offer or sale.

iii. Following the expiration of the Holder Purchase Option Period, the Company will be free to complete the proposed issuance or sale of securities in the Future Offering described in the Future Offering Notice with respect to which the Holder has declined to exercise the participation right set forth in this Section 5(r) on terms no less favorable to the Company than those set forth in the Future Offering Notice (except that the amount of securities to be issued or sold by the Company may be reduced); provided, that: (i) such issuance or sale is closed within sixty (60) calendar days after the expiration of the Holder Purchase Option Period and (subject to the extension of such period for a reasonable time not to exceed sixty (60) calendar days to the extent reasonably necessary to obtain any third-party approvals); and (ii) for the avoidance of doubt, the price at which the securities are sold is at least equal to or higher than the purchase price described in the Future Offering Notice. In the event the Company has not sold such securities within such time period, the Company may not thereafter issue or sell any such securities without first again offering such securities to the Holder in accordance with the procedures set forth in this Section 5(r).

iv. The closing of any purchase by the Holder pursuant to this Section 5(r) will be consummated concurrently with the consummation of the issuance or sale described in the Future Offering Notice. The Holder will deliver to the Company the purchase price for the securities purchased by it by certified or bank check or wire transfer of immediately available funds, unless otherwise provided by the Company or as otherwise provided pursuant to the terms of the Future Offering. Each party to the purchase and sale of the securities in the Future Offering will take all such other actions as may be reasonably necessary to consummate the purchase and sale including, without limitation, entering into such additional agreements as may be necessary or appropriate.

v. Notwithstanding anything to the contrary in this Warrant, the Holder will not be entitled to participate in the issuance of Company equity securities issued in connection with: (a) a grant to any existing or prospective consultant, employee, officer or director pursuant to any equity incentive plan or arrangement; (b) the conversion or exchange of any securities of the Company outstanding as of the Issuance Date into Common Stock, or the exercise of any then outstanding options, warrants or other rights to acquire such Common Stock provided that the terms of such securities have not been amended after their issuance; (c) any securities issued pursuant to acquisitions or strategic transactions by the Company of the stock, assets, properties or business of any person, company or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional benefits in addition to the investment of funds; or (d) any issuance of warrants or other similar rights to purchase equity securities to lenders or other institutional investors in any arm’s length transaction providing debt financing to the Company or any of its subsidiaries (“Financing Warrants”) where such Financing Warrants, together with all then outstanding Financing Warrants, are not equal to and not convertible into an aggregate of more than five percent (5%) of the outstanding Ordinary Shares on a fully diluted basis at the time of the issuance of such Financing Warrants (“Excluded Issuances”).
