On September 30, 2005, the Organization and Compensation Committee of Oglebay Norton Company (the "Company"), adopted the Oglebay Norton Company 2005 Executive Bonus Plan (the "Plan").

Under the Plan, eleven employees of the Company, including all five of the Company's named executive officers (the "Participants"), have the opportunity to earn a specific target bonus amount which will be paid upon achievement of financial goals (the "Bonus"). In order to earn any Bonus, total debt for the Company at year-end 2005 must be at or below $260 million. If debt is adequately reduced, Participants can receive up to target Bonus levels if shareholder equity is increased above the level forecasted for year-end 2005 in the Company's Disclosure Statement dated July 30, 2004, as amended and filed with the U.S. Bankruptcy Court.
