Imposing an impermissible fee

Q: Our pathology lab offered our services to a certain hospital. The hospital told our lab that many other labs also offered their services to them. They said that if we want, they will choose our lab and give us all their contracts, on condition that since they are giving us the business, our lab should pay them a stipulated fee as a token of appreciation. Is it permissible for our lab to pay the hospital this stipulated fee?
