Dear Bill:

         Now that Mario Gabelli has asked that we debate before institutional
shareholders in New York, and I have accepted as I assume you will, there is
another critical constituency which we should address as well - our employees
and retirees. They have already raised a number of very legitimate questions
with regard to the proxy contest, and I think we owe them the courtesy of a
fully informative meeting which would provide them the opportunity to hear
from both sides.

         I would propose that we hold such discussion in Wilmington at
everyone's earliest convenience and open it up to all Company employees and
retirees.

         Please let me know.

         All the best.

                                                          Sincerely,

                                                         /s/ Samuel J. Heyman
