jurisdictions, as Bank deems appropriate, in order to further perfect or protect Bank’s interest in the Collateral, including a notice that any disposition of the Collateral, by either the Borrower or any other Person, shall be deemed to
violate the rights of the Bank under the Code. 
 8. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever
necessary to reflect the changes described above.

and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any
other collateral securing the loan. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS,
CREDITS OR OTHER PROPERTY OF BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. 
 13. JURISDICTIONNENUE.

 NOW, THEREFORE, for good and valuable consideration, receipt of which is hereby

AGREEMENT 

To secure its obligations under the Loan Agreements, Grantor grants and pledges to Bank a security interest in all of Grantor’s
right, title and interest in, to and under its intellectual property (all of which shall collectively be called the “Intellectual Property Collateral”), including, without limitation, the following: 

1. Any and all copyright rights, copyright applications, copyright registrations and like protections in each work or authorship and

hereto (collectively, the “Copyrights”); 

 2. Any and all trade secrets, and any and all intellectual property rights in computer
software and computer software products now or hereafter existing, created, acquired or held; 
 3. Any and all design rights

Exhibit B attached hereto (collectively, the “Patents”); 
 5. Any trademark and servicemark rights,
whether registered or not, applications to register and registrations of the same and like protections, and the entire goodwill of the business of Grantor connected with and symbolized by such trademarks, including without limitation those set forth
on Exhibit C attached hereto (collectively, the “Trademarks”); 
 6. All mask works or similar rights
available for the protection of semiconductor chips, now owned or hereafter acquired, including, without limitation those set forth on Exhibit D attached hereto (collectively, the “Mask Works”); 

7. Any and all claims for damages by way of past, present and future infringements of any of the rights included above, with the right,
but not the obligation, to sue for and collect such damages for said use or infringement of the intellectual property rights identified above; 
 8. All licenses or other rights to use any of the Copyrights, Patents, Trademarks, or Mask Works and all license fees and royalties arising from such use to the extent permitted by such license or rights;

 9. All amendments, extensions, renewals and extensions of any of the Copyrights, Trademarks, Patents, or Mask Works; and

 10. All proceeds and products of the foregoing, including without limitation all payments under insurance or any indemnity or
warranty payable in respect of any of the foregoing. 
 Notwithstanding the foregoing, the security interest shall not apply to
any Excluded Property (as defined in the Loan Agreement). 
 This security interest is granted in conjunction with the security
interest granted to Bank under the Loan Agreements. The rights and remedies of Bank with respect to the security interest granted hereby are in addition to those set forth in the Loan Agreements and the other Loan Documents, and those which are now
or hereafter available to Bank as a matter of law or equity. Each right, power and remedy of Bank provided for herein or in the Loan Agreement or any of the Loan Documents, or now or hereafter existing at law or in equity shall be cumulative and
concurrent and shall be in addition to every right, power or remedy provided for herein and the exercise by Bank of any one or more of the rights, powers or remedies provided for in this Intellectual Property Security Agreement, the Loan Agreements
or any of the other Loan Documents, or now or hereafter existing at law or in equity, shall not preclude the simultaneous or later exercise by any person, including Bank, of any or all other rights, powers or remedies.
