As an FYI, the more restrictive a non-compete document is, generally the less enforceable it is. Courts look down upon preventing an individual the right to earn a living with skill sets that person has acquired over the course of their career. Novartis cannot stop you from working for another MS company completely. They may be able to enforce you not being able to work your current geography. There are a lot of precedents available where the courts have decided in favor of the individual and against the company. It will most likely depend on the exact location you intend to work, how different or similar that is from your current territory, and also if it was made clear to you that you were signing a non-compete. If enough of you testify that it was never made clear to you that you were signing a non-compete, then you've got a good case to have that document thrown out. Good luck!
