But Joseph M. Ahearn, Toy Biz's president, said yesterday that they had no such right, because a change of control at Marvel ended the shareholder agreement. He said that five of the eight directors chosen by the former Marvel management -- those directly connected to Ronald O. Perelman, the financier who had controlled Marvel -- had resigned. Speaking early yesterday afternoon, he said that the departed directors would be replaced by new directors chosen by the six remaining directors, and that their names would be announced later in the day. But no further announcement was made.
