HUTTON <EFH> ENDS PUROLATOR <PCC> BID Emery Air Freight Corp said it has entered into an agreement with E.F. Hutton Group Inc EFH under which Hutton will terminate its merger agreement with Purolator Courier Corp and its pending 35-dlr-per-share tender offer, effective April 13. Under its merger agreement, Hutton has the right to unilaterally terminate the merger agreement under certain circumstances, including its receipt of less than 66-2/3 pct of Purolator shares or the start of a higher competing tender offer, such as Emery's competing 40 dlr per share offer for Purolator stock. Yesterday, Hutton's PC Acquisition Corp subsidiary extended its tender offer, which was to have expired at midnight, for two more days. It said it only about 450,000 shares, or 6.5 pct, of Purolator shares had been tendered and not withdrawn, down from an 11.5 pct interest held earlier. Emery's bid expires April 28. Emery said pending the termination of PC Acquisition's merger agreement, PC has released Purolator from an agreement not to discuss Emery's acquisition proposal with Emery. Emery said as a result it is renewing its request that Purolatr enter into merger negotiations with it. Emery said if it were to acquire 51 pct of Purolator shares or control of the Purolator board, it has agreed not to dispute PC Acquisition's right to receive fees that Purolator agreed to pay if PC were unsuccessful in acquiring control of Purolator due to the acquisition of control by another party. The company said it has also agreed to let Purolator pay all of PC Acquisition's documented expenses in connection with the merger agreement up to three mln dlrs and Emery has agreed to pay the amounts itself should Purolator fail to do so.
