immediately available funds, equal to $3.25 times the number of Exercised Shares (the “Aggregate Exercise Price”).
The number of Exercised Shares and the Aggregate Exercise Price are set forth on the Holder’s signature page hereto. Within
five (5) Trading Days of the Closing Date, the Company shall deliver the Exercised Shares to the Holder in accordance with the

Warrant Shares” and, together with the Original Warrant Shares, the “Warrant Shares”)
and (ii) a replacement of the Original Warrant representing the balance, if any, of the Original Warrant Shares less the Exercised
Shares. The New Warrant shall be immediately exercisable at an exercise price of $5.50 per share (subject to adjustment as provided
therein) and will expire on July 21, 2022. The New Warrant shall otherwise be substantially in the form attached hereto on Exhibit

price, in immediately available funds, equal to $3.25 times the number of Exercised Shares (the “Aggregate
Exercise Price”). The number of Exercised Shares and the Aggregate Exercise Price are set forth on the
Holder’s signature page hereto. Within five (5) Trading Days of the Closing Date, the Company shall deliver the

representing the balance, if any, of the Original Warrant Shares less the Exercised Shares. The New Warrant shall be

behalf of the Company to the Holder regarding the Company, its business and the transactions contemplated hereby, is true and
correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to
make the statements made therein, in light of the circumstances under which they were made, not misleading.

MISCELLANEOUS

 

4.1 Registration Rights. Within 60 days of the Closing Date, the Company shall
use its best efforts to prepare and file with the Commission a registration statement (the
“Registration Statement”) covering the resale of the New Warrant Shares. The Registration Statement
shall contain substantially similar “Plan of Distribution” disclosure as that included in the resale registration
statement for the Original Warrant Shares. The Company shall use its commercially reasonable efforts (i) to cause the
Registration Statement to be declared effective by the Commission as promptly as possible after the filing thereof, and (ii)
to keep the Registration Statement continuously effective under the Securities Act until the earlier of (a) the date that all
of the New Warrant Shares covered by the Registration Statement have been sold or can be sold publicly without restriction or
limitation under Rule 144 (including, without limitation, the requirement to be in compliance with Rule 144(c)(1)), or (b)
the date that is five (5) years following the Closing Date. The Company shall promptly notify the Holder upon receiving
notification from the Commission that (x) the Registration Statement has been declared effective, or (y) the Commission has
entered a stop order or taken any similar action suspending the effectiveness of the Registration Statement. The Company
shall pay all of its fees and expenses incident to the performance of or compliance with its obligations under this
paragraph.

 

4.2 Notices. Any and all notices or other communications or deliveries required
or permitted to be provided hereunder shall be made in accordance with the provisions of the Original Warrant.

 

4.3 Survival. All warranties and representations (as of the date such
warranties and representations were made) made herein shall be considered to have been relied upon by the parties hereto and
shall survive the issuance of the New Warrant. This Agreement shall inure to the benefit of and be binding upon the
successors and permitted assigns of each of the parties; provided, that no party may assign this Agreement or the
obligations and rights of such party hereunder without the prior written consent of the other party hereto.

 

    	4

    	 

    

 

4.4 Execution. This Agreement may be executed in two or more counterparts, all
of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have
been signed by each party and delivered to the other party. Any signature delivered by facsimile or other electronic
transmission shall create a valid and binding obligation of the executing party with the same force and effect as if such
facsimile signature page were an original thereof.

 

4.5 Severability. If any provision of this Agreement is held to be invalid or
unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision
that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this
Agreement.

 

4.6 Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be determined pursuant to the Governing Law provision of the Original
Warrant.

 

4.7 Entire Agreement. This Agreement, the New Warrant and the Original Warrant
contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior agreements
and understandings, oral or written, with respect to such matters.

 

4.8 Construction. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language
used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules
of strict construction will be applied against any party.
