ALLEGHNEY INTERNATIONAL <AG> FACES ADDED COUNT Alleghney International Inc said the plaintiffs in the existing lawsuits opposing its sale requested an amendment to their complaint to include a class action count. Alleghney said the suit, filed in the U.S. District Court for the Western District of Pennsylvania, was aimed at blocking the sale of Alleghney to an affiliate of First Boston Inc. Allegheney said the additional count sought by the plaintiffs alleges the price to be offered for AI's common stock, 24.60 dlrs, is grossly unfair and one the purposes of the proposed sale is to absolve the individual defendants of liability in the lawsuit. The additional count among other forms of relief, requests an injunction against the defendants from taking any steps to accomplish the proposed sale, Alleghney said.
