I signed a noncompete for employment with a kentucky based corporation. They do not have offices in Texas. I worked from home in texas. Can the noncompete be inforced If i take a job with a competitor here in Texas?

i signed a noncompete letter with a Kentucky based corporation as a condition of employment. When i was terminated, i was given a one month severance. I've heard rumblings about them being non-enforceable in Texas,
The document references several items but specifically prohibits me from working for a competitor for one year within a 100 mile radius of any location where my old company has business.
Is this enforceable in Texas?

Secondly, on the first page, it specifically states "In consideration of Employee's employment by Employer as National Account Manager...". This is incorrect. I was hired as District Manager. As a District Manager, I worked from Home Based office in Texas -- where National Account Managers work from the main Corporate Office in Kentucky. does this mis-statement render the noncompete unenforceable?
