3. Member States shall provide that the revocation provided for in paragraph 1 may only be exercised after a reasonable time following the conclusion of the licence or the transfer of the rights. The author or performer shall notify the person to whom the rights have been licensed or transferred and set an appropriate deadline by which the exploitation of the licensed or transferred rights is to take place. After the expiry of that deadline, the author or performer may choose to terminate the exclusivity of the contract instead of revoking the licence or the transfer of the rights.
