Non-Competition Agreements When Buying a Business
If you're thinking of buying a business, you may also want to think about whether you'd mind if the seller went into direct competition with you after you take over. Competition isn't always a negative, but consider how it would affect you.
AllBusiness.com has a good article on non-competition agreements. In addition to explaining why you might want one, it talks about reasonable limits, geographically and in time, and offers key provisions that such an agreement should include. As with all their articles, it also provides additional links and resources.
