Several cultures contain a fable about a horse, a Farmer, and a wolf. After a time both plagued by the wolf the Farmer and horse agree to work together to defeat their common foe. The horse's speed and stamina combined with the Farmer's weapons and cleverness win out. The horse then asks the Farmer to remove the bridle and saddle - their agreement being at an end. "The hell you say." replies the Farmer, "Giddiyap Dobbin." as he applies the spurs with a will.
This parable is a warning about deals that don't work out so well. It's charming and memorable as such parables are when they are good, but a little hard to work with in real life. Most contracts are not about donning saddles and bridles to hunt down wolves. So, I'd like to offer a checklist for the mechanics of deals that work out well:
