WEST BANK, as Agent for and representative of the Lender Parties (in such capacity, the “Agent”). If there are no Guarantors
that are party to this Agreement, the term “Grantors” shall refer only to the Borrower.

 

WHEREAS, the Grantor
has granted a security interest in and continuing Lien on the Collateral (including the patents subject of this Agreement) to the
Agent pursuant to the Security Agreement, and desires to enter into this Agreement for purposes of affirming such grant to the
Agent, and providing a short-form medium to facilitate the recording of such security interest in the applicable governmental offices.

 

NOW, THEREFORE,
for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Grantor agrees as follows:

 

Section 1. Affirmation
and Grant of Security. The Grantor hereby affirms its grant to the Agent of, and grants to the Agent, a security interest
in and continuing lien on all of such Grantor’s right, title and interest in, to and under the patents listed on Schedule
I to secure the Secured Obligations.

 

Section 2. Recordation.
The Grantor authorizes and requests that the Commissioner of Patents and Trademarks and any other applicable government officer
record this Agreement.

 

Section 3. Grants,
Rights and Remedies. This Agreement has been entered into in conjunction with the provisions of the Security Agreement.
The Grantor does hereby acknowledge and confirm that the grant of the security interest hereunder to, and the rights and remedies
of, the Agent with respect to the Collateral are more fully set forth in the Security Agreement, the terms and provisions of which
are incorporated herein by reference as if fully set forth herein.

 

Section 4. Miscellaneous.
The Grantor agrees that neither this Agreement nor any term hereof may be changed, waived, discharged or terminated, except by
an instrument in writing signed by the party (including, if applicable, any party required to evidence its consent to or acceptance
of this Agreement) against whom enforcement of such change, waiver, discharge or termination is sought. This Agreement may be executed
in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together
shall constitute one and the same agreement.

 

Section 5. Governing
Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING
EFFECT TO ITS CHOICE OF LAW PRINCIPLES, EXCEPT TO THE EXTENT THAT THE UCC PROVIDES THAT THE PERFECTION OF THE SECURITY INTEREST
HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN
THE STATE OF NEW YORK.
