(i) each patent, patent application, utility model and statutory invention registration, all inventions claimed or disclosed therein and all improvements thereto (“Patents”) owned by the Grantor, including, without limitation, each Patent referred to in Schedule 1 hereto;

(ii) applications for any Patent together with all reissues, divisions, continuations, continuations-in-part, extensions and reexaminations thereof;

(iii) any and all claims for damages and injunctive relief for past, present and future infringement, 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

(iv) 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 foregoing.

Section 3. Recordation. Each Grantor authorizes and requests that the Commissioner for Patents record this Security Agreement.

Section 4. Execution in Counterparts. This 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.

Section 5. Grants, Rights and Remedies. This Security Agreement has been executed and delivered by the Grantors for the purpose of recording the grant of security interest with the U.S. Patent and Trademark Office. The security interest confirmed hereby has been granted to the Collateral Agent in connection with the General Security Agreement and is expressly subject to the terms and conditions thereof and does not create any additional rights or obligations for any party hereto.
