17. CANCELLATION AND RESCHEDULING

(a) Cancellation: Bookings once made cannot be cancelled.

(b) Rescheduling: Except through preemption, the telecast date specified in any Booking may not be modified unless the Station agrees, and unless a minimum of 4 weeks' prior written notice is received by the Station from the Advertiser or its Advertising Agent and such notice is accompanied by a new telecast schedule acceptable to the Station. Should less than 4 weeks' notice be given, any such change, if accepted by the Station, will be subject to a surcharge. In any event, no change will be accepted which would reduce the overall monetary value of the Booking in force and the rates applicable at the time of telecast will be applied to the revised schedule.
