than 20% of the outstanding shares of Common Stock under this Section 1.5, after giving effect to all such issuances, the number
of shares issuable pursuant to Sections 1.5.1, 1.5.2 and 1.5.3 shall be reduced so that the aggregate number of shares issued pursuant

The Seller hereby covenants
and agrees that the Seller will not, by any voluntary action, avoid or seek to avoid the observance or performance of its obligations
under this Section 1.5, and will at all times in good faith carry out all the provisions of this Section 1.5. Without limiting
the general nature of the foregoing, in the event of a Fundamental Transaction (as defined below), the Buyer shall provide in such
Fundamental Transaction that, in lieu of issuing the shares of Common Stock that may become issuable pursuant to this Section 1.5,
the Seller’s right to shares of Common Stock be satisfied by any successor to the Buyer or affiliate of such successor in
the Fundamental Transaction either (a) as a payment in cash equal to the value of such shares of Common Stock (without interest
or earnings), based on the amount payable to the Buyer’s stockholders in connection with the Fundamental Transaction under
any agreement pursuant to which the transactions constituting the Fundamental Transaction are effected, and/or (b) in shares of
the capital stock of any successor to the Buyer or affiliate of such successor, or other consideration (as applicable, the “Substitute
Consideration”), so long as such Substitute Consideration has, in the good faith judgment of the Board of Directors of the
Buyer a value and liquidity equal to or greater than the value of such shares of Common Stock that may otherwise become issuable
pursuant to this Section 1.5. As used herein, the term “Fundamental Transaction” means the occurrence of a merger,
consolidation, share exchange, tender offer, exchange offer or other form of reorganization or business combination in which the
Buyer is not the surviving corporation or in which the shares of Common Stock are deregistered under the Securities Exchange Act
of 1934, as amended (the “Exchange Act”). Buyer hereby represents that, as of the Closing Date, no future Fundamental
Transaction is contemplated, it has no current plan or intention to effect a Fundamental Transaction and it has not had any discussions

to the other party and until such time shall hold it in trust for the other party. The Buyer shall pay any applicable assignment,
recordal fees, or other fees payable for the recordal of the assignment of any Patents or any other Purchased Assets or for the

1.7.          Consent
of Third Parties. On the Closing Date, Seller shall assign to Buyer, and Buyer will assume, the Assigned Contracts, in each
case, to the extent permitted by, and in accordance with, applicable law. Notwithstanding anything to the contrary contained in
this Agreement, if the assignment or assumption of all or any portion of any rights or obligations under any Assigned Contract
shall require the consent of any other party thereto that has not been obtained prior to the Closing Date, this Agreement shall
not constitute an agreement to assign or otherwise transfer any rights or obligations under such Assigned Contract. In order,
however, to seek to provide Buyer the full realization and value of every such Assigned Contract, (a) as soon as practicable after
the Closing, Seller and Buyer shall cooperate in all reasonable respects to obtain the consent to the assignment of such Assigned
Contract; provided, that neither party shall be required to make any payment or agree to any material undertakings in connection
therewith.

4.6.         Brokers,
Finders, etc. All negotiations relating to this Agreement and the transactions contemplated hereby have been carried on without
the intervention of any person acting on behalf of the Buyer in such manner as to give rise to any valid claim against the Seller

as amended (the “Sarbanes-Oxley Act”) (such documents and any other documents filed by the Company with the
SEC, as have been supplemented, modified or amended since the time of filing, collectively, the “Buyer SEC Documents”).
As of their respective filing dates or, if supplemented, modified or amended since the time of filing, as of the date of the most
recent supplement, modification or amendment, the Buyer SEC Documents (i) did not at the time each such document was filed contain

Sarbanes-Oxley Act, and the rules and regulations promulgated thereunder, in each case as in effect on the date each such document
was filed. As of the date hereof, there are no material outstanding or unresolved comments received from the SEC with respect
to any of the reports filed by the Buyer with the SEC. The audited consolidated financial statements and unaudited consolidated
interim financial statements of the Buyer (including, in each case, any notes thereto) included in or incorporated by reference

dates of filing in all material respects with the then applicable accounting requirements and the published rules and regulations
of the SEC with respect thereto, (y) were prepared in conformity with GAAP (as in effect in the United States on the date of such
Buyer Financial Statement) applied on a consistent basis during the periods involved (except as may be indicated in the notes
thereto or, in the case of interim financial statements, for normal and recurring year-end adjustments that were not (or will
not be) material in amount or effect) and (z) present fairly, in all material respects, the financial position of the Buyer and
its consolidated subsidiaries and the results of their operations and their cash flows as of the dates and for the periods referred
to therein (except as may be indicated in the notes thereto or, in the case of interim financial statements, for normal and recurring
year-end adjustments that were not (or will not be) material in amount or effect). 

4.8.         Disclosure.
No representation or warranty by the Buyer contained in this Agreement, the Schedules, the Exhibits hereto nor written statement
or any certificate furnished or to be furnished by the Buyer to the Seller under this Agreement contains or will contain any untrue
statement of a material fact, or omits or will omit to state any material fact required to make the statements contained herein

thereof to provide to the Company an opinion of counsel selected by the transferor, reasonably acceptable to the Company, the
form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not
require registration of such transferred Shares under the Securities Act.

Legend. The certificate(s) representing the Shares, until such time as they are not required under Section 5.3, shall
bear the following or substantially similar restrictive legend:

WARRANT NOR ANY SUCH SECURITIES MAY BE OFFERED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED, TRANSFERRED OR OTHERWISE DISPOSED OF IN

of the Company), (iii) while such Shares are eligible for sale under Rule 144(b)(1) promulgated by the Commission pursuant to the
Securities Act or (iv) as soon as reasonably practicable following the receipt by the Company of a written request from the holder
thereof; provided that the request is received at least six month’s following the date that such Shares are issued pursuant

pursuant to the preceding sentence, the Company will, no later than ten (10) days following the delivery by the holder to the Company
or the Company’s transfer agent of a certificate representing Shares containing a restrictive legend, deliver or cause to
be delivered to such holder a certificate representing such Shares that is free from all restrictive and other legends.
