Relative to no compete agreements, in the Florida courts, one of the District Courts of Appeal ruled that if your employer/company that you signed the original no compete agreement with sells the business to another party then the original no compete contract is null and void absent the new owner getting the employee to sign a new one.
The principle in the case is that a no compete contract is particular to the original employee/employer relationship, that each party has a set of rights and expectations flowing from that agreement, and that those rights and expectations are not transferable with a change in the ownership of the business.
So, the question is, has the original employer that you signed the no compete agreement with sold or transfered the ownership of the business. If so, that might give you a way out.
In principle this seems to hold water, but you might have to get a lawyer to check to see what the controlling legal authority is in your state.
