Exhibitors are obligated to utilize the services of Official Contractors for services such as freight handling, electrical, plumbing, telephone, catering and drayage. The Official Service Contractor has control of the exposition floor, aisles, loading docks, service and storage areas. In order to coordinate all activities and for security purposes while in the convention center, exhibitors who choose to use a non-official contractor(s), must complete and submit this form by March 4. All contractors must comply with all rules and regulations as posted on the Web site and in the exhibitor manual.
