WHEREAS, Stockholder Beneficially Owns (as defined herein) 6,199,845 shares of Class A Stock (the “Shares”); and

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, the application of such term or provision to other persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction, and all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of this Agreement is not affected in any manner materially adverse to any party.
