I sold a business, and may face non compete litigation soon

I sold a business based in PA which sold medical alarms over the internet. The buyer is based in Ohio. As part of the sale agreement there is a 5 year non-compete provision.

1 year after signing, I was offered a job by a competitor to be a field rep here in PA. I got a letter from the buyer's attorny fishing for information, and replied back to it saying "if your client intends to litigate, then proceed.

Here are the points I think help me...
1. I sold a company that did business over the internet only. As a field rep I am doing a completely different form of business
2. I have never solicited a former client
3. I have never solicited a former referral source
4. When I sold my company, as part of the sale, the buyer got my website, 800 #, and customer lists.
5.I sell a new type of product in the marketplace that did not exsist when I sold my company
6. I have never said a bad thing about the people whio bought my business
7.I do not have any trade secrets, all of the information regarding prospects in my territory is public knowledge
8. If I loose this job, I will have to declare bankruptcy, and loose my house
9.I waited a year before getting back into the business

If they proceed with litigation, I need an attorney
