Under the terms of the Agreement and Plan of Merger (the "Merger Agreement") dated as of September 11, 1995 among Duriron, Wolverine Acquisition Corp. and Durametallic, at the effective time of the merger on November 30, 1995, each option outstanding under the Durametallic Corporation 1991 Stock Option Plan (the "Durametallic Option Plan") became exercisable for Duriron Common Stock, on the basis of 3.1132 shares of Duriron Common Stock for each share of Durametallic's Common Stock, $5.00 par value per share ("Durametallic Shares"), for which the option was exercisable prior to the effective time of the merger, at an exercise price per share equal to the exercise price per share in effect prior to the effective time of the merger divided by 3.1132. In addition, as required by the Merger Agreement, the Durametallic Corporation Executive Incentive Bonus Plan (the "Durametallic Bonus Plan") was amended to provide that, after the effective time of the merger, persons entitled to receive Durametallic Shares under the Durametallic Bonus Plan will receive, instead, on the same terms and conditions, Duriron Common Stock, on the basis of 3.1132 shares of Duriron Common Stock for each Durametallic Share otherwise issuable under the Durametallic Bonus Plan. This Post-Effective Amendment No. 1 on Form S-8 is being filed for the purpose of registering the offer and sale of the Duriron Common Stock (the "Plan Shares") that may be issued in lieu of Durametallic Shares upon the exercise of options granted under the Durametallic Option Plan and under the Durametallic Bonus Plan in accordance with the Merger Agreement. The 6,458,558 shares of Duriron Common Stock registered pursuant to the Registration Statement were sufficient to include the Plan Shares.
