Training Agreements Legal Question

I’ve been with AGE coming up on 4 years. Like every new FC I signed a 5 year training agreement stating that I would have to pay them back $50K if I leave within 5 years. With the Wachovia takeover (sorry merger) is there any legal ground that this agreement is no longer valid given the change in control? My plan is to go indy so I’m curious about what to expect from the firm regarding this. Also curious if 401K employer $ vest under a merger or if I would be out of luck on this.
