 NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, each Grantor hereby agrees as follows: 
 1. DEFINED TERMS. All capitalized terms used
but not otherwise defined herein have the meanings given to them in the Security Agreement and/or the Credit Agreement. 
 2. GRANT OF
SECURITY INTEREST IN PATENT COLLATERAL. Each Grantor hereby grants to Agent, for the benefit of the Lender Group and the Bank Product Provider, a continuing first priority security interest in all of such Grantor’s right, title and interest
in, to and under the following, whether presently existing or hereafter created or acquired (collectively, the “Patent Collateral”): 
 (a) all of its Patents and Patent Intellectual Property Licenses to which it is a party including those referred to on Schedule I hereto; 
 (b) all reissues, continuations or extensions of the foregoing; and 







 (c) all products and proceeds of the foregoing, including, without limitation, any claim by such Grantor
against third parties for past, present or future infringement or dilution of any Patent or any Patent licensed under any Intellectual Property License. 
 3. SECURITY AGREEMENT. The security interests granted pursuant to this Patent Security Agreement are granted in conjunction with the security interests granted to Agent, for the benefit of the Lender Group and

 4. AUTHORIZATION TO SUPPLEMENT. If any Grantor shall obtain rights to any new patentable inventions or become entitled to the benefit of any patent application or patent for any reissue, division, or continuation, of any patent, the

Section 4, Grantors hereby authorize Agent unilaterally to modify this Agreement by amending Schedule I to include any such new patent rights of Grantors. Notwithstanding the foregoing, no failure to so modify this Patent Security
