Where a finder is appointed on an exclusive basis, the finder has exclusive rights to (ie only they are allowed to) search for, and introduce to the principal, client leads in the territory specified in the Agreement. Under an exclusive appointment, the principal also agrees not to appoint any other finders in the territory.
Where a finder is appointed on a non-exclusive basis, the principal can appoint other finders in the territory and the finder may need to compete with others when looking for client leads.
