Allied Stores took more anti-takeover actions.

The retailer added venom to its “poison pill” plan by adopting a provision that seriously threatens the hostile takeover bid of Campeau Corp. of Canada. Allied, whose stores include Brooks Bros., Bonwit Teller and Ann Taylor, said the new provision to its anti-Campeau plan could prevent the real estate developer from paying dividends crucial to its offer. Campeau has sweetened its original bid by promising to provide a one-time dividend of as much as $3 per share to existing Allied shareholders.
