I agree further that this Release of Claims may be pleaded as a full defense to any action, suit, arbitration or other proceeding covered by the terms hereof that is or may be initiated, prosecuted or maintained by me or my descendants, dependents, heirs, executors, administrators or assigns. By signing this Release of Claims, I acknowledge that I intend to waive and release all rights known or unknown that I may have against the Company Releasees under these and any other laws.

I acknowledge and agree that as of the date I execute this Release of Claims (the “Release Effective Date”), I have no knowledge of any facts or circumstances that give rise or could give rise to any claims under any of the laws listed in the preceding paragraph and that I have not filed any claim against any of the Company Releasees before any local, state, federal or foreign agency, court, arbitrator, mediator, arbitration or mediation panel, or other body (each individually a “Proceeding”).
