Sec. 4. Whenever any bank or trust company requests bank service from a bank service corporation which supplies the same type of bank service to other banks or trust companies and the applying bank or trust company is competitive with any bank or trust company which holds stock in the bank service corporation, such corporation must agree to render such services, and either

     (a) issue stock to the applying bank or trust company and furnish bank services to such applying bank or trust company on the same basis as to other banks or trust companies holding stock in the bank service corporation, or

     (b) furnish bank services to the applying bank or trust company at rates no higher than necessary to reflect fairly the cost of such services including the reasonable cost of the capital provided to such corporation by its stockholders, at the option of the banking service corporation, unless comparable services at a competitive overall cost are available to the applying bank or trust company from another source, or unless the furnishing of the services sought by the applying bank or trust company would be beyond the practical capacity of the bank service corporation.

     In any action or proceeding to enforce the duty imposed by this section, or for damages for the breach thereof, the burden shall be upon the bank service corporation to prove the availability of bank services from another source.
