WHEREAS, the Company and Subscriber desire to
amend the Subscription Agreement in order to align its terms with the proposed amendment to the Merger Agreement.


 


NOW, THEREFORE, in consideration of the foregoing
and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally
bound hereby, the Company and Subscriber hereto hereby agree as follows:


 


1.

2.                  
Subscriber hereby consents, for all purposes under the Subscription Agreement, to the Merger Agreement Amendment, in the form attached
hereto as Annex A.


 


3.

4.                  
Effective as of the effective date of the Merger Agreement Amendment, Section 6 of the Subscription Agreement shall be amended
to replace “December 7, 2022” with “February 28, 2023”.

this Amendment and Consent shall prevail. Upon the effectiveness of this Amendment and Consent, each reference in the Subscription
Agreement to “this Agreement,” “hereunder,” “hereof,” “herein,” or words of like
import shall mean and be a reference to the Subscription Agreement as amended hereby, and each reference to the Subscription

to the principles of conflicts of laws that would otherwise require the application of the laws of any other state.


 


8.                  
Any Action based upon, arising out of or related to this Amendment and Consent shall be finally resolved pursuant to Sections 8(q)-(r)
of the Subscription Agreement, which are hereby incorporated by reference and shall apply to this Amendment and Consent as if set forth
herein in their entirety, mutatis mutandis.


 


9.                  
This Amendment and Consent may be executed and delivered in one or more counterparts (including by electronic mail, in .pdf or
