You acknowledge that the restrictions contained in this Non-Compete section are reasonable and necessary in view of your position with CSG and that your compensation and benefits under this agreement are sufficient consideration for your acceptance of these restrictions.  If any of the restrictions contained in this section are found by a court to be unreasonable or excessively broad as to area or time, or otherwise unenforceable, then the parties intend that the restrictions contained in this section be modified by the court so as to be reasonable and enforceable as so modified.  

Non-Solicitation of Employees
