refused to enforce certain agreements not to compete.  Therefore, in furtherance
and not in derogation of the provisions of this Agreement, Company and
Employee agree that in the event a court of competent jurisdiction should for
any reason decline to enforce any of said covenants, that his Agreement shall be
deemed to be modified to restrict Employee's competition with Company to the
maximum extent in time, geography and otherwise as the court shall deem
enforceable and/or to grant Company such other relief at law or in equity as
shall be reasonable necessary to protect the interest of Company.
