Can I accept job from employers former client

I am in the IT field and worked for a consulting/staffing company that farms its employees out to other companies. I recenetly left in September 2002 to look for a better employer. When I was hired, I signed an at-will employment agreement that also contained confidentiality clauses and the promise not to accept a job from any of their clients for a period of 12 months after termination of employment. In reality we are not provided with any confidential information or specialized training. They just send us to clients to do work with the skills we already have.

One of their former clients, where I worked until June 2001 and who has not done any more business with them since December 2001 (and will not do business with them again due to past disputes and problems) has offered me a job and would like to send me to training on new products and tools that they use.

My former employer is claiming that they must pay a fee, but the former client claims there are no agreements in force at this time that warrant a fee.

Could my former employer win a lawsuit against ME for breeching my employment agreement if the client does not pay a fee?
