Agreement are fair and reasonable in light of all of the facts and circumstances
of the relationship between Employee and Company; however, Employee and Company
are aware that in certain

 
circumstances courts have refused to enforce certain agreements not to compete.

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.
