 2. Exercise of Warrant. 

(a) Manner of Exercise. 

(i) Cash Exercise. This Warrant may be exercised, in whole or in part, at any time or from time to time, during the period commencing
as of 9:30:01 a.m., New York time, on the Initial Exercise Date and ending as of 5:30 p.m., New York time, on the Expiration Date (the “Exercise Period”), for ONE MILLION (1,000,000) fully paid and non-assessable shares of
Common Stock (the “Warrant Shares”), for an exercise price per share equal to the Exercise Price, by delivery to the Company at its headquarters, or at such other place as is designated in writing by the Company, of: 

(1) a duly executed Notice of Exercise, substantially in the form of Attachment I attached hereto and incorporated by reference
herein; 
 (2) this Warrant; and 

(3) subject to Section 2(a)(ii) below, payment of an amount in cash equal to the product of the Exercise Price multiplied by the
number of Warrant Shares being purchased upon such exercise, with such payment being in the form of a wire transfer of immediately available U.S. funds to an account designated in writing by the Company. 

The date on which the Company receives the Notice of Exercise, this Warrant, and the Exercise Price payable with respect to the Warrant Shares
being purchased shall be deemed to be the date of exercise (the “Date of Exercise”). 
 (ii) Cashless Exercise.
Notwithstanding the provisions of Section 2(a)(i)(3) above (requiring payment by wire transfer), the Company agrees that, if at the time of exercise hereof there is no effective registration statement registering, or the prospectus
contained therein is not available for the issuance of the Warrant Shares to the Holder, then Holder shall have the right at such time to exercise this Warrant in full or in part on a cashless basis, computed using the following formula: 

X = Y (A - B) 

       A 

Where: 
 X = The number of
Warrant Shares to be issued to the Holder pursuant to this cashless exercise; 
 Y = The number of Warrant Shares in respect of which the
net issue election is made; 
 A = The Fair Market Value (as defined below) of one Warrant Share at the time the cashless exercise election
is made; and 
 B = The Exercise Price then in effect at the time of such exercise. 

The term “Fair Market Value” shall mean, on any given day: (A) if the class of Warrant Shares is exchange-traded, the average
of the closing sales prices per share of the class of Warrant Shares for the 

  
 - 2 - 








 
ten (10) consecutive Trading Days ending on the day that is two (2) Trading Days prior to the applicable date of determination of Fair Market Value; or (B) if the class of Warrant
Shares is not listed or admitted to trading on any securities exchange but is regularly traded in any over-the-counter market, then the average of the bid and ask prices per share of the class of Warrant Shares for the ten (10) consecutive
Trading Days ending on the day that is two (2) Trading Days prior to the applicable date of determination of Fair Market Value; or (C) if the class of Warrant Shares is not traded as described in clauses (A) or (B), then the per share
fair market value of the class of Warrant Shares as determined in good faith by the Company’s Board of Directors. As used in this Warrant, the term “Trading Days” shall have the meaning ascribed to such term in the Purchase Agreement.

 (b) Delivery of Certificates. Certificates for Warrant Shares purchased hereunder shall be transmitted by the transfer agent of
the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company (“DTC”) through its Deposit Withdrawal Agent Commission system if the Company is a participant in such system and
such Warrant Shares are eligible for delivery in such a manner, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise within three Business Days from the delivery to the Company of the Notice of
Exercise, surrender of this Warrant and payment of the aggregate Exercise Price as set forth above (the “Delivery Period”). This Warrant shall be deemed to have been exercised on the date on which this Warrant is surrendered and
payment of the Exercise Price is received by the Company. 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 on which all of the criteria described in the immediately preceding sentence have occurred, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment
is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open. If fewer than
all of the Warrant Shares purchasable under the Warrant are purchased, the Company will, upon such partial exercise, execute and deliver to the Holder a new Warrant (dated as of the Issue Date), in the same form and tenor as this Warrant, evidencing
that portion of the Warrant not exercised. 
 (c) Delivery of Electronic Shares. In lieu of delivering physical certificates
representing the Warrant Shares issuable upon exercise (provided that the transfer agent is participating in the DTC Fast Automated Securities Transfer program and provided further that the Holder provides the transfer agent with information
required in order to issue such Warrant Shares to the Holder electronically), upon the request of the Holder as set forth in the Notice of Exercise, but only if the Warrant Shares may be issued without restrictive legends, the Company shall cause
its transfer agent to electronically transmit, within the Delivery Period, the Warrant Shares issuable upon exercise to the Holder by crediting Holder’s account with DTC through its Deposit Withdrawal Agent Commission system. Any delivery not
effected by electronic transmission shall be effected by delivery of physical certificates. 
 (d) No Fractional Shares. If a
fractional share of Warrant Shares would, but for the provisions of this Section 2(d), be issuable upon exercise of the rights represented by this Warrant, the Company shall (i) round a half share or greater to be delivered to
Holder up to the next whole share and (ii) round a less-than-half share to be delivered to Holder down to the nearest whole share. 

(e) No Charge to Holder Upon Issuance. The issuance of Warrant Shares upon exercise of this Warrant shall be made without charge to
Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares (other than any transfer taxes resulting from the issuance of Warrant Shares to any
person other than Holder). 

  
 - 3 - 








 (f) Reservation of Shares. During the Exercise Period, the Company shall reserve and keep
available out of its authorized but unissued Common Stock such number of Warrant Shares issuable upon the full exercise of this Warrant. All Warrant Shares which are so issuable shall, when issued and upon the payment of the applicable Exercise
Price, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges and not subject to the pre-emptive rights of any holder of Common Stock or any other class or series of stock of the Company. During the
Exercise Period, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance upon exercise of this Warrant. 

(g) Limitations on Exercises. Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable
by the Holder hereof to the extent (but only to the extent) that after giving effect to such issuance after exercise, such Holder or any of its affiliates, as a result of such exercise, would beneficially own in excess of the Beneficial Ownership
Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant
with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder or any of
its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company, in both cases which are subject to a limitation on conversion or exercise analogous to the limitation contained
herein (including, without limitation, any other Warrants) beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2(g), beneficial ownership shall be
calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 2(g) applies, the determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which such securities shall be exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise
shall be deemed to be the Holder’s determination of whether this Warrant may be exercised (in relation to other securities owned by the Holder together with any Affiliates), in each case subject to the Beneficial Ownership Limitation. 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. To ensure compliance with this restriction,
the Holder will be deemed to represent to the Company each time it delivers a Notice of Exercise that such notification has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the
accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For
purposes of this Section 2(g), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the
Company’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written notice by the Company or the Company’s transfer
agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two 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 this Warrant, by the Holder or its Affiliates since the
date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the
issuance of shares of Common Stock issuable upon exercise of this Warrant held by the Holder. The Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial


  
 - 4 - 








 
Ownership Limitation provisions of this Section 2(g), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the Beneficial Ownership Limitation provisions of this Section 2(g) shall continue to apply. Any
such increase or decrease will not be effective until the 61st day after such notice is delivered to the Company. The Beneficial Ownership Limitation provisions of this paragraph shall be
construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(g) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership
Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. 

3. Adjustments in Certain Events. The number, class, and price of Warrant Shares for which this Warrant may be exercised are subject to adjustment from
time to time upon the happening of certain events as follows: 
 (a) Subdivisions, Combinations and Other Issuances. If the
outstanding shares of the Company’s Common Stock are divided into a greater number of shares, by forward stock split or otherwise, or a dividend in stock is paid on the Common Stock, then the number of shares of Warrant Shares for which the
Warrant is then exercisable will be proportionately increased and the Exercise Price will be proportionately reduced. Conversely, if the outstanding shares of Common Stock are combined into a smaller number of shares of Common Stock, by reverse
stock split or otherwise, then the number of Warrant Shares for which the Warrant is then exercisable will be proportionately reduced and the Exercise Price will be proportionately increased. The increases and reductions provided for in this
Section 3(a) will be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of the Warrants nor the price payable for such percentage upon such
exercise will be affected by any event described in this Section 3(a). 
 (b) Merger, Consolidation, Reclassification,
Reorganization, Etc. In case of any change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete liquidation, purchase of all or substantially all the assets of the Company, or other change in
the capital structure of the Company, then, as a condition of such change, lawful and adequate provision will be made so that the Holder will have the right thereafter to receive upon the exercise of the Warrant the kind and amount of shares of
stock or other securities or property to which the Holder would have been entitled if, immediately prior to such event, the Holder had held the number of Warrant Shares obtainable upon the exercise of the Warrant. In any such case, appropriate
adjustment will be made in the application of the provisions set forth herein with respect to the rights and interest thereafter of the Holder, to the end that the provisions set forth herein will thereafter be applicable, as nearly as reasonably
may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of the Warrant. The Company will not permit any change in its capital structure to occur unless the issuer of the shares of stock or other
securities to be received by the Holder, if not the Company, agrees to be bound by and comply with the provisions of this Warrant. 
 (c) If
securities of the Company or securities of any subsidiary of the Company are distributed pro rata to holders of Common Stock, such number of securities will be distributed to the Holder or its assignee upon exercise of its rights hereunder as such
Holder or assignee would have been entitled to if this Warrant had been exercised prior to the record date for such distribution. The provisions with respect to adjustment of the Common Stock provided in this Section 3 will also apply to
the securities to which the Holder or its assignee is entitled under this Section 3(c).

 4. No Rights as a Stockholder. Nothing contained in this Agreement shall be construed as conferring upon
the Holder any rights whatsoever as a stockholder of the Company, either at law or in equity, including without limitation, or Holders the right to vote or to consent or to receive notice as a stockholder in respect of any meetings of stockholders
for the election of directors the right to receive dividends or any other matter. 
 5. Restrictions on Transfer; Legends. 

(a) Registration or Exemption Required. Assuming the accuracy of the representations and warranties of the Holder contained in herein,
this Warrant has been issued in a transaction exempt from the registration requirements of the Securities Act by virtue of Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder and exempt from state registration or
qualification under applicable state laws. The Holder acknowledges that it has been advised by the Company that this Warrant and the Warrant Shares issuable upon exercise thereof have not been registered under the Securities Act. Neither this
Warrant nor the Warrant Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws. If, at the time of
the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or
blue sky laws, the Company may require, as a condition of allowing such transfer (i) that the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form,
substance and scope customary for opinions of counsel in comparable transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the
holder or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an “accredited investor” as defined in Rule 501(a) promulgated under the
Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act. 
 (b) Representations
of Holder. The Holder represents and warrants that it has acquired this Warrant and will acquire the Warrant Shares for its own account for investment and not with a view to the sale or distribution thereof or the granting of any participation
therein, and that the Holder has no present intention of distributing or selling to others any of such interest or granting any participation therein. The Holder acknowledges that the Warrant and Warrant Shares must be held indefinitely unless a
subsequent disposition thereof is registered under the Securities Act or registered or qualified under any applicable state securities or “blue-sky” laws or is exempt from registration and/or qualification. The Holder has no need for
liquidity in its investment in the Company, and is able to bear the economic risk of such investment for an indefinite period and to afford a complete loss thereof. The Holder is an “accredited investor” as such term is defined in Rule 501
(the provisions of which are known to the Holder) promulgated under the Act. 
 (c) Restrictive Legend. The Holder understands that
until such time as the Warrant Shares have been registered under the Securities Act, or otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the
number of securities as of a particular date that can then be immediately sold, this Warrant and the Warrant Shares, as applicable, shall bear a restrictive legend in substantially the form set forth on the cover page of this Warrant (and a
stop-transfer order may be placed against transfer of the certificates for such securities). 
 (d) Disposition of Warrant or Warrant
Shares. With respect to any offer, sale or other disposition of this Warrant or any Warrant Shares prior to registration of such Warrant Shares, the Holder agrees to give written notice to the Company prior thereto, describing briefly the
manner thereof, together 

  
 - 6 - 








 
with evidence, reasonably satisfactory to the Company (which shall include such representation of the transferee regarding investment intent as the Company may request, to the effect that such
offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such Warrant Shares and indicating whether or not under
the Securities Act certificates for this Warrant or Warrant Shares to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving
such written notice and reasonably satisfactory evidence, the Company, as promptly as practicable but no later than seven (7) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of
this Warrant or Warrant Shares, all in accordance with the terms of the notice delivered to the Company. If the Company determines that the evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly
with details thereof after such determination has been made. Notwithstanding the foregoing, any Warrant Shares may be offered, sold or otherwise disposed of in accordance with Rule 144 under the Act and in compliance with the applicable
statutory resale restrictions imposed by state securities laws, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144
and the applicable resale restrictions imposed by state securities laws have been satisfied. Each certificate representing this Warrant or the Warrant Shares thus transferred shall bear a legend as to the applicable restrictions on
transferability in order to ensure compliance with such laws, unless pursuant to an opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to
its transfer agent in connection with such restrictions. 
 (e) Removal of Restrictive Legends. The certificates evidencing the
Warrant Shares shall not contain any legend restricting the transfer thereof: (A) while a registration statement covering the sale or resale of the Warrant Shares is effective under the Securities Act and such legend removal is permitted under
applicable securities laws (including compliance with the prospectus delivery requirements of the Securities Act), or (B) following any sale of such Warrant Shares pursuant to Rule 144, or (C) if such Warrant Shares are eligible for sale
under Rule 144(b)(1), or (D) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) and the Company shall have received an
opinion of counsel to the Holder in form reasonably acceptable to the Company to such effect (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to its transfer agent if
required by the transfer agent to effect the issuance of the Warrant Shares, as applicable, without a restrictive legend or removal of the legend hereunder. The Company agrees that at such time as the Unrestricted Conditions are met, it will, no
later than three (3) Trading Days following the delivery by the Holder to the Company or the transfer agent of a certificate representing Warrant Shares, issued with a restrictive legend, deliver or cause to be delivered to such Holder a
certificate (or electronic transfer) representing such Warrant Shares that is free from all restrictive and other legends. 
 (f)
Notwithstanding anything else herein, the Holder agrees that it shall not, to its knowledge, transfer all or any portion of this Warrant or any of the Warrant Shares to any other person or entity, which person or entity is either (i) the
beneficial holder of more than 4.99% of the Common Stock of the Company or (ii) would become, by reason of such transfer, the beneficial holder of more than 4.99% of the Common Stock of the Company. 

6. Notices; Adjustments. 
 (i) All
notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified; (ii) when sent by confirmed electronic mail or facsimile if sent during normal
business hours of the recipient, and if not, then on the next business day; (iii) two (2) Business Days after having been sent by registered or certified 

  
 - 7 - 








 
mail, return receipt requested, postage prepaid; or (iv) one (1) Business Day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written
verification of receipt. All communications shall be sent to the Company or to Holder, as applicable, at the respective addresses set forth on the signature page to the Purchase Agreement or at such other address(es) as they may designate,
respectively, by ten (10) days advance written notice to the other party hereto. 
 (ii) Upon the occurrence of any adjustments
pursuant to Sections 3(a) or 3(c) hereof, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment in accordance with the terms hereof and furnish to
Holder a certificate setting forth such adjustment and showing in detail the facts upon which such adjustment is based. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining
the holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date on which any such record is to be taken for the purpose of such dividend or
distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall mail to the Holder, at least ten (10) days prior to the date of the occurrence of any such
event, a notice specifying such date. If the approval of any stockholders of the Company shall be required in connection with any transaction contemplated by Section 3(b) above, then, the Company shall cause to be mailed to the Holder at
least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating the date on which such transaction 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 transaction. Notwithstanding the immediately preceding sentences, however, if the date on which the
Company is obliged to provide notice hereunder to the Holders is prior to a public announcement relating to the events set forth and on such date the Company’s securities are traded or quoted on any recognized national securities exchange or
quotation system, then such notice shall be provided to each Holder simultaneously with the notice provided to the Company’s common stockholders. Failure to give such notice, or any defect therein, shall not, however, affect the legality or
validity of any such action. 
 7. Non-Circumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its
certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be reasonably required to protect the rights of the Holder. 

8. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of New York, without regard to conflict of
law principles, and notwithstanding the fact that one or more counterparts hereof may be executed outside of the state, or one or more of the obligations of the parties hereunder are to be performed outside of the state. 

9. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and, in the case of loss, theft, or destruction, of indemnity reasonably satisfactory to it, and, if mutilated, upon surrender and cancellation of this Warrant, the Company will execute and deliver a new
Warrant, having terms and conditions identical to this Warrant, in lieu hereof. 
 10. Modification and Waiver of Warrants. This Warrant may only be
modified or amended or the provisions hereof waived with the written consent of the Company and the Holder. No waivers of any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a
further or continuing waiver of any such term, condition or provision. 

  
 - 8 - 








 11. Successors. This Warrant shall be binding and inure to the benefit of the parties and their respective
successors and assigns hereunder; provided that this Warrant may be assigned by Holder only in compliance with the conditions specified in and in accordance with all of the terms of this Warrant. This Warrant does not create and shall not be
construed as creating any rights enforceable by any other person or corporation. 
 12. Headings. The headings used in this Warrant are used for
convenience only and are not to be considered in construing or interpreting this Warrant. 
 13. Saturdays, Sundays, Holidays. If the last or
appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday or a Sunday or shall be a legal holiday in the State of New York, then such action may be taken or such right may be
exercised on the next succeeding day not a legal holiday. 
 14. Severability. If any provision of this Warrant shall be held to be invalid or
unenforceable, such invalidity or unenforceability shall not affect any other provisions of this Warrant. 
 15. Execution and Counterparts. This
Warrant may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, and such counterparts together shall constitute only one instrument. Any one of such counterparts shall be sufficient
for the purpose of proving the existence and terms of this Warrant, and no party shall be required to produce an original or all of such counterparts in making such proof. 

16. Acceptance. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.
