Attn:
Mr. Scott Mahoney

Chief
Executive Officer, President and Director

 

Dear
Mr. Mahoney:

 

This
letter (the “Agreement”) constitutes the agreement between Taronis Technologies Inc. (the “Company”) and
The Benchmark Company, LLC (“Benchmark”) pursuant to which Benchmark shall act, on a best efforts and exclusive basis,
as the co-agent for a private placement of Convertible Preferred securities by the Company (the “Offering”) of approximately
$40 Million or such other amount or type of securities as shall be determined by the parties.

 

The
terms of the Offering shall be mutually agreed upon by the Company and any counter-parties and nothing herein implies that Benchmark
would have the power or authority to bind the Company or an obligation for the Company to complete the Offering. The Company expressly
acknowledges and agrees that the execution of this Agreement does not ensure the successful completion of the Offering.

 

A.
Fees and Expenses. In connection with the services described above, the Company shall pay to Benchmark in the aggregate,
the following compensation:

 

1.
Placement Agent Fees. Upon the successful Closing of the Offering, the Company shall pay to Benchmark fees (the “Offering
Fee”) equivalent to both (i) a cash fee of an aggregate amount equal to two (2%) percent of the net proceeds received by
the Company from the Offering (excluding the conversion of any warrants sold in the Offering); and (ii) warrants (the “Placement
Agent Warrants”) to purchase two (2%) percent of that number of securities issued, or issuable upon conversion upon any
convertible securities, in the Offering. The form of Placement Agent Warrant is attached hereto as Exhibit A.

 

The
exercise price of the Placement Agent Warrants shall be 110% of the offering price per share and the expiration date shall be
5 years from the closing of the Transaction.

 

2.
Expenses. In addition to any fees payable to Benchmark hereunder, whether or not the Offering is consummated, the Company
hereby agrees to reimburse Benchmark for all reasonable travel and other necessary out-of-pocket expenses of third parties incurred
directly in connection with Benchmark’s engagement hereunder, including the reasonable fees and expenses of Benchmark counsel,
if required and provided that Benchmark is solely responsible for any fees of counsel. Any aggregate expense(s) in excess of $1,000
shall be approved by the Company in advance (provided, however, that such expense cap in no way limits or impairs the indemnification
and contribution provisions of this Agreement). Reimbursement by the Company shall occur upon the earlier of the receipt of an
invoice from Benchmark, the Closing, or the expiration or termination of this Agreement

 

    	 

    	 

    

 

B.
Term and Termination of Engagement. The term (the “Term”) of Benchmark’s engagement will begin on the
date hereof and end on the earlier of the close of the Offering or fifteen (15) days after the receipt by either party hereto
of written notice of termination. Notwithstanding anything to the contrary contained herein, the provisions concerning indemnification,
contribution and the Company’s obligations to pay fees and reimburse expenses contained herein will survive any expiration
or termination of this Agreement

 

C.
Use of Information; Confidentiality. The Company will furnish Benchmark such written information as Benchmark reasonably
requests in connection with the performance of their services hereunder. The Company understands, acknowledges and agrees that,
in performing its services hereunder, Benchmark will use and rely entirely upon such information as well as publicly available
information regarding the Company and other relevant third parties and that Benchmark does not assume responsibility for independent
verification of the accuracy or completeness of any information, whether publicly available or otherwise furnished to it, concerning
the Company or otherwise relevant to the Offering including, without limitation, any financial information, forecasts or projections
considered by Benchmark in connection with the provision of their services.

 

Benchmark
agrees that all nonpublic information obtained in connection with their engagement hereunder will be held in strict confidence
and will be used by it solely for the purposes of performing their obligations relating to their engagement hereunder; provided,
that nothing herein shall prevent Benchmark from disclosing any such information (a) in accordance with an order of any court
or administrative agency or in any pending legal or administrative proceeding, or (b) to the extent that such information (i)
was or becomes publicly available other than by reason of disclosure by Benchmark in violation of this Agreement or (ii) was or
becomes available to Benchmark or their affiliates from a source that is not known by Benchmark to be subject to a confidentiality
obligation to the Company. This undertaking by Benchmark shall automatically terminate one (1) year following the last to occur
of the completion of the Offering or termination of the engagement hereunder. At the request of the Company, Benchmark will execute
a commercially reasonable nondisclosure agreement in connection with the delivery and use of such information. At Company’s
request, Benchmark will promptly return to the Company, or destroy, any and all materials containing such confidential information
except to the extent that Benchmark are required to maintain such information in accordance with legal or regulatory requirements
or consistent with Benchmark’s data retention policies.

 

D.
Publicity. In the event of the consummation or public announcement of the Offering, Benchmark shall have the right to disclose,
with the Company’s prior written approval, their participation in the Offering, including, without limitation, the placement
at their cost of “tombstone” advertisements on their website and in financial and other newspapers and journals subject
to all applicable laws.

 

E.
Securities Matters. The Company shall be responsible for any and all compliance with the securities laws applicable to
it, including Regulation D and the Securities Act of 1933, as amended (the “Securities Act”), and Rule 506 promulgated
thereunder, and unless otherwise agreed in writing, all state securities (“blue sky”) laws. Benchmark agrees to cooperate
with counsel to the Company in that regard. Benchmark will comply with all applicable federal and state securities laws, rules,
and regulations in connection with their activities hereunder and all applicable broker-dealer registration and compliance rules
and regulations. As the Offering involves a private placement of securities, the Benchmark will take no action that will jeopardize
the Company’s private placement exemption from federal and state securities laws.

 

    	 

    	 

    

 

F.
Indemnity.

 

1.
In connection with the Company’s engagement of Benchmark hereunder, the Company hereby agrees to indemnify and hold harmless
Benchmark and their affiliates, and the respective controlling persons, directors, officers, partners, members, shareholders,
agents, registered representatives, registered principals and employees of any of the foregoing (collectively the “Indemnified
Persons”), from and against any and all claims, actions, suits, proceedings (including those members or shareholders), investigations,
damages, liabilities and expenses incurred by any of them (including the reasonable fees and expenses of counsel), as incurred,
(collectively a “Claim”), that are (A) directly related to or arise out of (i) any actions taken or omitted to be
taken (including any untrue statements made or any statements omitted to be made) by the Company, or (ii) any actions taken or
omitted to be taken by any Indemnified Person in connection with the Company’s engagement of Benchmark, or (B) otherwise
relate to or arise out of Benchmark’s activities on the Company’s behalf under the Benchmark’s engagement hereunder,
and the Company shall reimburse any Indemnified Person for all expenses (including the reasonable fees and expenses of counsel)
as incurred by such Indemnified Person in connection with investigating, preparing or defending any such claim, action, suit or
proceeding. The Company will not, however, be responsible for any Claim to have resulted from the bad faith, gross negligence,
willful misconduct, illegal acts of or any breach of this Agreement by any person seeking indemnification for such Claim, including
any Indemnified Person. The Company further agrees that no Indemnified Person shall have any liability to the Company for or in
connection with the Company’s engagement of Benchmark except for any Claim incurred by the Company as a result of such Indemnified
Person’s bad faith, gross negligence, willful misconduct, illegal acts or any breach of this Agreement.

 

2.
Neither Party will, without the prior written consent of the other Party, settle, compromise or consent to the entry of any judgment
in any pending or threatened Claim in respect of which indemnification may be sought hereunder (whether or not any Indemnified
Person is an actual or potential party to such Claim), unless such settlement, compromise or consent includes an unconditional,
irrevocable release of each Indemnified Person from any and all liability arising out of such Claim.

 

3.
Promptly upon receipt by an Indemnified Person of notice of any complaint or the assertion or institution of any Claim with respect
to which indemnification is being sought hereunder, such Indemnified Person shall promptly notify the Company in writing of such
complaint or of such assertion or institution. If the Company so elects, the Company will assume the defense of such Claim, including
the employment of counsel reasonably satisfactory to such Indemnified Person and the payment of the reasonable fees and expenses
of such counsel. In the event, however, that legal counsel to such Indemnified Person reasonably determines that having common
counsel would present such counsel with a conflict of interest or if the defendant in, or target of, any such Claim, includes
an Indemnified Person and the Company, and legal counsel to such Indemnified Person reasonably concludes that there may be legal
defenses available to it or other Indemnified Persons different from or in addition to those available to the Company, then such
Indemnified Person may employ its own separate counsel to represent or defend him, her or it in any such Claim and the Company
shall pay the reasonable fees and expenses of such counsel. Notwithstanding anything herein to the contrary, if the Company fails
timely or diligently to defend, contest, or otherwise protect against any Claim, the relevant Indemnified Party shall have the
right, but not the obligation, to defend, contest, compromise, settle, assert cross-claims, or counterclaims or otherwise protect
against the same, and shall be fully indemnified by the Company therefor, including without limitation, for the reasonable fees
and expenses of its counsel and all amounts paid as a result of such Claim or the compromise or settlement thereof. In addition,
with respect to any Claim in which the Company assumes the defense, the Indemnified Person shall have the right to participate
in the defense of such Claim and to retain his, her or its own counsel therefor at his, her or its own expense.

 

    	 

    	 

    

 

4.
The Company agrees that if any indemnity sought by an Indemnified Person hereunder is held by a court to be unavailable for any
reason then (whether or not Benchmark are the Indemnified Person), the Company and Benchmark shall contribute to the Claim for
which such indemnity is held unavailable in such proportion as is appropriate to reflect the relative benefits to the Company,
on the one hand, and Benchmark on the other, in connection with Benchmark’s engagement referred to above, subject to the
limitation that in no event shall the amount of the Benchmark’ s contribution to such Claim exceed the amount of fees actually
received by Benchmark from the Company pursuant to Benchmark’s engagement. The Company hereby agrees that the relative benefits
to the Company, on the one hand, and Benchmark on the other, with respect to Benchmark’ engagement shall be deemed to be
in the same proportion as (a) the total value paid or proposed to be paid or received by the Company or its members as the case
may be, pursuant to the Offering (whether or not consummated) for which Benchmark is engaged to render services bears to (b) the
fee paid or proposed to be paid to Benchmark in connection with such engagement.

 

5.
The Company’s indemnity, reimbursement and contribution obligations under this Agreement (a) shall be in addition to, and
shall in no way limit or otherwise adversely affect any rights that any Indemnified Person may have at law or at equity and (b)
shall be effective whether or not the Company is at fault in any way.

 

G.
Conflicts of Interest. Notwithstanding any other provision of this letter, Benchmark represents and warrants that Benchmark
and their affiliates have no material conflict of interest in connection with the assignment contemplated by this Agreement. During
the term of this engagement, Benchmark will promptly advise the Company in writing of any conflict of interest detrimental to
the Company of which Benchmark become aware.

 

H.
Limitation of Engagement to the Company. The Company acknowledges that Benchmark has been retained only by the Company,
that Benchmark is providing services hereunder as independent contractors (and not in any fiduciary or agency capacity) and that
the Company’s engagement of Benchmark is not deemed to be on behalf of, and is not intended to confer rights upon, any member,
shareholder, owner or partner of the Company or any other person not a party hereto as against Benchmark or any of its affiliates,
or any of its affiliates’ respective officers, directors, controlling persons (within the meaning of Section 15 of the Securities
Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), partners, employees, registered
principals, registered representatives or agents. Unless otherwise expressly agreed in writing by Benchmark, no one other than
the Company or its affiliates is authorized to rely upon this Agreement or any other statements or conduct of Benchmark, and no
one other than the Company or its affiliates is intended to be a beneficiary of this Agreement. The Company acknowledges that
any recommendation or advice, written or oral, given by Benchmark to the Company in connection with Benchmark’s engagement
is intended solely for the benefit and use of the Company’s management and directors in considering the Offering, and any
such recommendation or advice is not on behalf of, and shall not confer any rights or remedies upon, any other person or be used
or relied upon for any other purpose. Benchmark shall not have the authority to make any commitment binding on the Company. The
Company, in its sole discretion, shall have the right to reject any investor or counterparty introduced to it by the Benchmark.
The Company agrees that it will perform and comply with the covenants and other obligations set forth in the purchase agreement
and related transaction documents, as applicable, between the Company and the investors in the Offering, and that Benchmark will
be entitled to rely on the representations, warranties, agreements and covenants of the Company contained in such purchase agreement
and related transaction documents as if such representations, warranties, agreements and covenants were made directly to Benchmark
by the Company.

 

    	 

    	 

    

 

I.
Limitation of Benchmark’s Liability to the Company. Benchmark and the Company further agree that neither Benchmark
nor any of its affiliates or any of its respective officers, directors, controlling persons (within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act), partners, employees, registered representatives, registered principals
or agents shall have any liability to the Company, its security holders or creditors, or any person asserting claims on behalf
of or in the right of the Company (whether direct or indirect, in contract, tort, for an act of negligence or otherwise) for any
losses, fees, damages, liabilities, costs, expenses or equitable relief arising out of or relating to this Agreement or the services
rendered hereunder, except for losses, fees, damages, liabilities, costs or expenses that arise out of or are based on any action
of or failure to act by Benchmark and that have resulted solely from the bad faith, gross negligence, willful misconduct, illegal
act or any breach of this Agreement by Benchmark.

 

J.
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable
to agreements made and to be fully performed therein. Any disputes that arise under this Agreement, even after the termination
of this Agreement, will be heard only in the state located in the County of New York, State of New York. The parties hereto expressly
agree to submit themselves to the jurisdiction of the foregoing courts in the County of New York, State of New York. The parties

out of or relating to this Agreement, the party in whose favor the final judgment or award shall be entered shall be entitled

Warrant
No.: PA-

Number
of Shares of Common Stock:

Date
of Issuance: January [  ], 2020 (“Issuance Date”)

 

Taronis
Technologies, Inc., a Delaware corporation, (the “Company”), hereby certifies that, for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, [                                      ], the registered
holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to
purchase from the Company, at the Exercise Price (as defined below) then in effect, upon surrender of this Placement Agent Warrant
to Purchase Common Stock (including any Placement Agent Warrants to Purchase Common Stock issued in exchange, transfer or replacement
hereof, the “Warrant”), at any time or times on or after the Stockholder Approval Date (as defined in the Securities
Purchase Agreement (as defined below)) (the “Initial Exercisability Date”), but not after 11:59 p.m., New York
Time, on the Expiration Date (as defined below), [                                      ] (                 ) fully paid nonassessable shares of Common Stock (as defined below) (the
“Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings
set forth in Section 14. This Warrant is being issued to the Holder in connection with the Company’s sale of securities
pursuant to that certain Securities Purchase Agreement, dated as of December [  ], 2019 (the “Subscription Date”),
by and among the Company and the investors referred to therein (the “Securities Purchase Agreement”).

 

    	 

    	 

    

 

EXERCISE
OF WARRANT.

 

Mechanics
of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section
1(f)), this Warrant may be exercised by the Holder on any day on or after the Date of Issuance in whole or in part, by (i) delivery
of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s
election to exercise this Warrant and (ii) (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied
by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”)
in cash or by wire transfer of immediately available funds. The Holder shall not be required to deliver the original Warrant in
order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant
Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to
purchase the remaining number of Warrant Shares. On or before the second Business Day following the date on which the Company
has received each of the Exercise Notice and the Aggregate Exercise Price (the “Exercise Delivery Documents”),
the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the
Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the second Trading Day following
the date on which the Company has received all of the Exercise Delivery Documents (the “Share Delivery Date”),
the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of shares of Common Stock
to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC
through its Deposit Withdrawal Agent Commission system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated
Securities Transfer Program, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate,
registered in the Company’s share register in the name of the Holder or its designee, for the number of shares of Common
Stock to which the Holder is entitled pursuant to such exercise. Upon delivery of the Exercise Delivery Documents, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this
Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the
date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted in connection
with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise
is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and
in no event later than three Business Days after any exercise and at its own expense, issue a new Warrant (in accordance with
Section 5(d)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under
this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common
Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be
rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance
and delivery of Warrant Shares upon exercise of this Warrant.

 

Exercise
Price. For purposes of this Warrant, “Exercise Price” means $[  ] subject to adjustment as provided herein.

 

    	 

    	 

    

 

Company’s
Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to the Holder within
three (3) Trading Days of receipt of the Exercise Delivery Documents, a certificate for the number of shares of Common Stock to
which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s
balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise
of this Warrant, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) shares
of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that
the Holder anticipated receiving from the Company (a “Buy-In”), then, in addition to all other remedies available
to the Holder, the Company shall, within three Business Days after the Holder’s request and in the Holder’s discretion,
either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions,
if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s
obligation to deliver such certificate (and to issue such shares of Common Stock) or credit such Holder’s balance account
with DTC shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing
such shares of Common Stock or credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal
to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing
Bid Price on the date of exercise.

 

Disputes.
In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the
Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance
with Section 10.

 

Limitation
on Exercises. 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, such Person (together with such Person’s affiliates)
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 (A) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person
and its affiliates and (B) 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. Except as set
forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). 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 (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing
with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any
other notice by the Company or the 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, the Company shall within one (1) Business Day 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 by the Holder
and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The provisions of
this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section
1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership
limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

 

    	 

    	 

    

 

ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from
time to time as follows:

 

If
the Company at any time on or after the Date of Issuance subdivides (by any stock split, stock dividend, recapitalization or otherwise)
one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased.
If the Company at any time on or after the Date of Issuance combines (by combination, reverse stock split or otherwise) one or
more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately
prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased.
Any adjustment under this Section 2(a) shall become effective at the close of business on the date the subdivision or combination
becomes effective.

 

Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price
to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

 

WARRANT
HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in such Person’s
capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital
of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in
such Person’s capacity as the Holder of this Warrant, any of the rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock,
consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise,
prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise
of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to
purchase any securities (upon exercise of this Warrant or otherwise) or as a shareholder of the Company, whether such liabilities
are asserted by the Company or by creditors of the Company. Notwithstanding this Section 3, the Company shall provide the Holder
with copies of the same notices and other information given to the shareholders of the Company generally, contemporaneously with
the giving thereof to the shareholders.

 

    	 

    	 

    

 

NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or
through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities,
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will
at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the
rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any
shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all
such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable
shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the Warrants are outstanding, take
all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose
of effecting the exercise of the Warrants, 100% of the number of shares of Common Stock as shall from time to time be necessary
to effect the exercise of the Warrants then outstanding (without regard to any limitations on exercise).

 

REISSUANCE
OF WARRANTS.

 

Transfer
of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company
will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 5(d)), registered as the
Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less

the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 5(d)) representing the right to

NOTICES.
The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable
detail a description of such action and the reason therefore. Without limiting the generality of the foregoing, the Company will
give written notice to the Holder immediately upon any adjustment of the Exercise Price, setting forth in reasonable detail, and
certifying, the calculation of such adjustment.

 

AMENDMENT
AND WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may take any
action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the
written consent of the Holder; provided that no such action may increase the exercise price of any Warrant or decrease the number
of shares or class of stock obtainable upon exercise of any Warrant without the written consent of the Holder. No such amendment
shall be effective to the extent that it applies to less than all of the holders of the Warrants then outstanding.

 

GOVERNING
LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction,
validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without
giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions)
that would cause the application of the laws of any jurisdictions other than the State of New York.

 

CONSTRUCTION;
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.

 

DISPUTE
RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two Business Days
of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company
are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three Business Days
of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two Business
Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected
by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s
independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may
be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten Business
Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s
determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error.

 

    	 

    	 

    

 

REMEDIES,
OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative and in addition
to all other remedies available under this Warrant, at law or in equity (including a decree of specific performance and/or other
injunctive relief), and nothing herein shall limit the right of the Holder right to pursue actual damages for any failure by the
Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will
cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees
that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other
available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond
or other security being required.

 

TRANSFER.
This Warrant may be offered for sale, sold, transferred or assigned without the consent of the Company.

 

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).
