JLL Partners Inc. has again extended its offer to purchase all of the restricted voting shares of Patheon Inc., a Canadian drug company with factories in several countries. As of Monday, the New York-based investment firm had about 73.5 million of Patheon's restricted voting shares, representing 57 per cent of the class. JLL said yesterday it had extended the offer, which will now expire 10 days from the mailing of a formal notice of extension. It didn't give a date for the mailing. The investment firm has continued its creeping takeover despite the opposition of Patheon's board, which says JLL's offer of $2 (U.S.) a share is inadequate. PTI (TSX) fell 1 cent (Canadian) to $2.59.
