Sorry if you haven't read the papers prior to the start of the meeting with out a good excuse I would consider giving you a verbal warning and if repeated a written one and putting you on poor performance procedure.
If I am chair I run the meeting - I once told the company founder to sit down and let some one else speak :-)
This rule should come from the top if I was chairman of a company and any director/attendee turned up having not read the papers I woudl be having words with them.
