Thrall Car Manufacturing Company, an Illinois corporation ("Thrall") and Thrall
Car Management Company, Inc., a Delaware corporation ("Newco") entered into a
merger transaction pursuant to an Agreement and Plan of Merger dated August 13,

shares of common stock, $1.00 par value of Registrant ("Common Stock"),
$165,500,000 (subject to adjustment as described in the Merger Agreement) and
the right to receive additional payments, not to exceed $45,000,000 over a five

production levels.

         Pursuant to the Merger Agreement, Registrant and Newco entered into a
Stockholder's Agreement ("Stockholder's Agreement") and a Registration Rights
Agreement (the "Registration Rights Agreement") at the closing of the Merger.
Pursuant to the Stockholder's Agreement, Newco was granted certain governance
