A federal court order temporarily blocking Shamrock Holdings’ $2.4-billion takeover bid for Polaroid Corp. is expected to be lifted after the Burbank investment company amended its offer for the Cambridge, Mass., instant photography company. Under Shamrock’s amended offer, its $42-a-share offer is contingent on whether a Delaware Chancery Court judge scraps a Polaroid employee stock plan that Shamrock contends was designed as an anti-takeover shield. A ruling on the stock plan is expected in several weeks.
