RECITALS


 


Borrower and Bank are parties to that certain
Loan and Security Agreement dated as of March 30, 2018 (as amended from time to time, the “Agreement”).
The parties desire to amend the Agreement in accordance with the terms of this Amendment.


 


NOW, THEREFORE, the parties agree as follows:


 


		1)	Bank hereby waives any and all of Borrower’s violations of the Primary Depository covenant,
as more particularly described in Section 6.6 of the Agreement (as in effect immediately prior to the effectiveness of this Amendment),
occurring on or before the date of this Amendment for maintaining Cash outside Bank in excess of the amounts permitted thereunder.



 


		2)	Section 2.5(c) of the Agreement is hereby amended and restated, as follows:



 


(c) Success
Fee. Upon a Liquidity Event, Borrowers shall pay to Bank a fee of $1,050,000. Notwithstanding anything to the contrary in this
Agreement, this Section 2.5(c) shall survive any termination of this Agreement; and


 


		3)	Section 6.6 of the Agreement is hereby amended and restated, as follows:



 


6.6 Primary

Bank or Bank’s affiliates. Notwithstanding the above, Borrower shall be permitted to maintain an aggregate amount not to
exceed $250,000 in one or more accounts outside of Bank. Prior to maintaining any investment accounts with Bank’s affiliates,
the applicable Borrower, Bank, and any such affiliate shall have entered into a securities account control agreement with respect
to any such investment accounts, in form and substance reasonably satisfactory to Bank.


 


		4)	Unless otherwise defined, all initially capitalized terms in this Amendment shall be as defined
in the Agreement. The Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its respective
terms and hereby is ratified and confirmed in all respects. Except as expressly set forth herein, the execution, delivery, and
performance of this Amendment shall not operate as a waiver of, or as an amendment of, any right, power, or remedy of Bank under
the Agreement, as in effect prior to the date hereof. Each Borrower ratifies and reaffirms the continuing effectiveness of all
agreements entered into in connection with the Agreement.
