a statement of reasonable length specifying its opinion on the merits of the
Auction Transaction;

         (e) In the event an Auction Transaction is not consummated on or prior

under Rule 14f-1 of the Exchange Act, which MICA and the Steel Parties will use
all reasonable efforts to satisfy as soon as practicable, the Persons who are
members of the Board at such time will resign and will cause such members to be
replaced with designees of the Steel Parties (resulting in the Board being
composed solely of designees of the Steel Parties) and (ii) if requested by the
Steel Parties, MICA will promptly call the annual meeting of shareholders, to be
scheduled as soon as practicable but in no case later than 45 days after the end
of the Auction Period, for the purpose of electing the Board of Directors of

maximizes shareholder value. In addition, if during the Auction Period any Steel

   11
         (b) MICA. MICA, on behalf of itself and all of its affiliates,
successors and assigns ("related parties"), hereby releases, acquits and forever
discharges the Steel Parties, together with their respective present and former
affiliates, officers, directors, employees, agents, attorneys, successors and

including but not limited to (i) any such claims, causes of action, demands,
expenses and damages relating to or arising out of the Action or the Rights Plan
