I would leave in your situation in a heart-beat. If leaving is not a credible option the company won't pay you a fair market rate and won't treat you with respect. I am not a lawyer, but if the company comes after you with a non-compete it seems reasonable that you could sue them for your back pay. Assuming your non-compete is for a year or so this is almost a wash in terms of salary especially when factoring how much more money you'll make over the long run with a higher salary.

The fact that you are even asking this question means you probably know the answer already - you have the most information about your situation so ultimately you should treat all advice here with a grain of salt.
