It shall be a violation of this act for a franchisor to terminate, cancel or fail to renew a franchise without good cause. For the purposes of this act, good cause for terminating, canceling, or failing to renew a franchise shall be limited to failure by the franchisee to substantially comply with those requirements imposed upon him by the franchise.
