Item 1.02.    Termination of a Material Definitive Agreement
On April 12, 2006, Oglebay Norton Company, an Ohio corporation (the "Company"), announced that it had obtained the requisite two-thirds consent to terminate, and effective April 12, 2006 had terminated, the Registration Rights Agreement, dated January 31, 2005, between the Company and certain Subscribers of the Company's Series A Convertible Preferred Stock, par value $0.01 per share (the "convertible preferred stock"), including the Company's Chairman of the Board of Directors and certain entities controlled by him.  The Subscribers had acquired shares of the convertible preferred stock pursuant to a commitment agreement, dated as of February 23, 2004, and as amended on June 29, 2004, November 15, 2004, November 23, 2004 and December 20, 2004.
