Modify the item of non-competition

The Employment Agreement has the item of non-competition, "Because of the highly proprietary nature of Employee's employment, Employee agrees that during the two year period following the termination of Employee's employment with the Company, Employee will not become employed by, or act as a consultant to, any organization whose principal business focus is the development or sale of analytical,statistical software including, without limitation, SAS Institute, Inc., Minitab, Inc., International Business Corporation, and Systat Software, Inc. " I think it's too strict. Could you help me that what the normal content of the item is? Thank you very much
