Sometimes you sell the store, but not the property, so you can use clause 19. Or the buyer wants a right of pre-emption for the premises. This prevents suppliers from becoming competitors in a given geographic area, perhaps 2 years and enough kilometers, to keep them away from the district, suburb, city, region or countryside. In fact, why agree to buy a business, if the owner can simply arrange the street downstairs and keep much of the business based on personal relationships and reputation. The nature of this agreement is that the seller gives no warranty, so the buyer has little protection. What he sees is what he receives. The reason for the sale is irrelevant. The document is not the sale of a business as a continuation business, but of assets in a “breakup” situation.
