What is the required action for a Bft franchisee if they become aware of someone infringing on Bft's marks?

Franchisee agrees to notify Franchisor immediately in writing if it becomes aware that any person who is not a licensee of Franchisor is using or infringing upon any of the Marks. Franchisee may not communicate with any person other than Franchisor and its counsel in connection with any such use or infringement. Franchisor will have discretion to determine what steps, if any, are to be taken in any instance of unauthorized use or infringement of any of its Marks and will have complete control of any litigation or settlement in connection with any claim of an infringement or unfair competition or unauthorized use with respect to the Marks. Franchisee will execute any and all instruments and documents and will assist and cooperate with any suit or other action undertaken by Franchisor with respect to such unauthorized use or infringement such as by giving testimony or furnishing documents or other evidence. Franchisor will be responsible for legal expenses incurred by Franchisor in connection with any litigation or other legal proceeding involving such third-party. Franchisor shall not be liable for any legal expenses of Franchisee unless (a) pre-approved in writing by Franchisor in its discretion, and (b) the action proceeds or arises out of Franchisee's authorized use of the Marks hereunder.
