Non Compete in California

I joined a firm in 2001 and signed their confidentiallity agreement. In Jan 03 I was terminated and signed a termination agreement that included this origional confidentiallity agreement.

I went to work for a competitor on March 03. Today I recieved a document that states that "I should refrain from contact with "former Employeers" customers for a period of 6 months." The actuall agreement says 1 year.

I was never provided a list of all IXOS customers. I only had direct visability to my account list, occasional access to names of other customers when we provided reference accounts to prospective customers and web site public access to a list of published customers.

Although the wording is "Customers" I feel they will try to take legal action to prevent me from contacting all prospect accounts that I had while at my former employeer or that contact me.

The reall issue is the fact that they can begin legal action which would cost me money.

I want to avoid any legal issues as I am not of the type to litigate. What options do I have?
