The term “concession agreement” is used in two slightly different ways in the business world. Both refer to a type of negotiated contract which gives a company the right to do business, with some specific requirements. In one sense, it refers to a contract between a foreign company and a government, in which the company signs a concession agreement so that it can do business in that government's country. In a second sense, this type of agreement is one which grants the concessionaire the exclusive right to do business in a particular area or venue in exchange for some carefully negotiated terms. (WiseGEEK)

CONCESSION AGREEMENT A negotiated contract between a company and a government that gives the company the right to operate a specific business within the government's jurisdiction, subject to certain conditions. A concession agreement may also refer to an agreement between the owner of a facility and the concession owner or concessionaire that grants the latter exclusive rights to operate a specified business in the facility under specified conditions. Regardless of the type of concession, the concessionaire usually has to pay the party that grants it the concession ongoing fees that may either be a fixed amount or a percentage of revenues.
