Strategic Buying a small broker

Asking for a friend. $10MM packaging company gets some business from industry brokers, a common practice. Broker has $1MM in sales and nets $350K a year. Broker is nearing retirement and offering to sell his "business" to the strategic. I don't believe the strategic can do all the $1MM of work that the broker manages. Let's say it's $500K. Is there a deal there that makes sense, for either party? I couldn't imagine paying a multiple of a small amount of cash flow that is not backed by some contract or exclusivity. I would think the broker should just work until he retires and maybe there is a small revenue share thereafter for 12 months but it just seems like more trouble than it is worth and fraught with issues of non-compete, non-circumvention and no guaranty buyer keeps the business.
