 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, each Pledgor agrees as follows: 
 Grant of Security. Each Pledgor hereby grants to the
Collateral Agent for the ratable benefit of the Secured Parties a security interest in all of such Pledgor’s right, title and interest in and to the following (the “Collateral”): 

the patents and patent applications set forth in Schedule A hereto (the “Patents”); 

all reissues, divisions, continuations, continuations-in-part, extensions, renewals and reexaminations of any of the
foregoing, all rights in the foregoing provided by international treaties or conventions, all rights corresponding thereto throughout the world and all other rights of any kind whatsoever of such Pledgor accruing thereunder or pertaining thereto;

 any and all claims for damages and injunctive relief for past, present and future infringement, dilution,
misappropriation, violation, misuse or breach with respect to any of the foregoing, with the right, but not the obligation, to sue for and collect, or otherwise recover, such damages; and 

any and all proceeds of, collateral for, income, royalties and other payments now or hereafter due and payable with
respect to, and supporting obligations relating to, any and all of the Collateral of or arising from any of the foregoing. 

provided that notwithstanding anything to the contrary contained in the foregoing clauses (i) through (iv), the security interest
created hereby shall not extend to, and the term Collateral, shall not include any lease, license or other agreement to the extent that (and only for so long as) a grant of a security interest therein would violate or invalidate such lease, license,
or agreement, or create a right of termination in favor of any other party thereto (other than any Pledgor), in each case to the extent not rendered unenforceable pursuant to applicable provisions of the UCC or other applicable law, provided, that
the Collateral includes proceeds and receivables of any property excluded under the foregoing proviso, the assignment of which is expressly deemed effective under the UCC notwithstanding such prohibition. 

Security for Obligations. The grant of a security interest in, the Collateral by each Pledgor under this Patent Security Agreement
secures the payment of all Obligations of such Pledgor now or hereafter existing under or in respect of the Collateral Documents (as such Collateral Documents may be amended, amended and restated, supplemented, replaced, refinanced or otherwise
modified from time to time (including any increases of the principal amount outstanding thereunder)), whether direct or indirect, absolute or contingent, and whether for principal, reimbursement obligations, interest, premiums, penalties, fees,
indemnifications, contract causes of action, costs, expenses or otherwise. Without limiting the generality of the foregoing, this Patent Security Agreement secures, as to each Pledgor, the payment of all amounts that constitute part of the Secured
Obligations (as defined in the Security Agreement) that would be owed by such Pledgor to any Secured Party under the Collateral Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, or
reorganization or similar proceeding involving a Credit Party. 







 Recordation. Each Pledgor authorizes and requests that the Commissioner for Patents
and any other applicable government officer record this Patent Security Agreement. 
 Execution in Counterparts. This
Patent Security 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. 

Grants, Rights and Remedies. This Patent Security Agreement has been entered into in conjunction with the provisions of the
Security Agreement. Each Pledgor does hereby acknowledge and confirm that the grant of the security interest hereunder to, and the rights and remedies of, the Collateral Agent with respect to the Collateral are more fully set forth in the Security
