This is way too complicated of a situation to discuss on a message board. You should contact an attorney who handles non-compete cases to get a formal opinion on your options.
The bottom line: The fact that you signed a non-compete agreement does not automatically mean you are bound by the agreements terms. Non-compete agreements are only enforceable when used to protect a legitimate business interest. In this situation, the agreement may be subject to attack on the grounds that there is no legitimate business interest. Further, you have the issue of possibly illegal conduct that triggered your resignation. If there really was illegal conduct, a court would likely give that significant weight in its analysis.

My response to this question is a response to a hypothetical situation based on limited facts. I am not your attorney; you are not my client and we do not have an attorney-client relationship. If you need a lawyer, you should contact one in your area. If you would like to talk with me about your case, you can call my office.
