DART GROUP RAISES SUPERMARKETS GENERAL <SGL> BID <Dart Group Corp> said it has raised its offer to acquire Supermarkets General Corp to 42.00 dlrs in cash and three dlrs in exchangeable preferred stock per Supermarkets General share from 41.75 dlrs per share in cash. The company said it would also be willing to negotiate a plan with the Supermarkets General board under which Supermarkets General shareholders would have a common stock interest in the combined company. It said it remains willing to negotiate all terms of the proposed acquisition. The original bid was worth about 1.62 billion dlrs. Dart said the preferred stock in the new bid would be exchangeable for a new class of Supermarkets General debt securities that would be developed by Dart and Supermarkets. The new proposal would be subject to approval by the Supermarkets General board, it said. The new bid was contained in a letter to the Supermarkets General board. In Woodbridge, N.J., Supermarkets General -- responding to a previous letter to its board by Dart -- said "Your conduct indicates to us that no transaction involving trust and confidence can be entered into with you. Your propaganda and missstatements will not panic our board." Dart, in its previous letter, had alleged that Supermarkets General executives were seeking millions of dollar in severance and tax payments from Dart.
