MARK IV CORRECTS AGREEMENT WITH BAIRD <BATM> Mark IV Industries Inc <IV>, which has said it may consider a bid to seek control of Baird Corp, said Baird has not agreed to hold off on any defensive measures without giving Mark IV at least 24 hours notice. In a filing with the Securities and Exchange Commission, Mark IV corrected a statement it made yesterday in another SEC filing in which it listed several agreements reached with Baird, including that Baird would not take any anti-takeover steps without providing at least 24 hours notice. Mark IV said it was later told by Baird that Baird had given no such assurance.
