CITIZENSHIP CERTIFICATION



United States merchant marine laws require that, in order for Oglebay Norton Company to continue to own and operate vessels
in the coastwise trade, at least 75% of its outstanding stock must be owned by United States citizen. The Second Amended and Restated Articles of Incorporated of Oglebay Norton Company, dated January 31, 2005, as the same may be amended from time to
time (Amended Articles), provides that any transfer or purported transfer of shares of Common Stock that would result in ownership by Foreigners (as defined below) of more than a specified percentage (the Permitted
Percentage) of the stock then outstanding will be subject to certain restrictions, reservations and remedies as described in the Amended Articles. The Companys Board of Directors can vary the Permitted Percentage between 25% and 22 1/2%,
depending on the extent of the margin that the Board determines is necessary to ensure compliance with the United States merchant marine laws. The Company will send to the holder of this certificate without charge a copy of the provisions of the
Amended Articles setting forth the restrictions on transfer, reservations, and remedies within five days after receipt of written request therefor.



No transfer of the Series A Convertible Preferred Shares represented by this certificate will be registered unless the following Citizenship
Certification (or a separate form of Citizenship Certification satisfactory to the Company) is completed and signed by the transferee and submitted to the transfer agent.



The transferee certifies that the transferee



 ̈is a Foreigner



 ̈is not a Foreigner



and that the beneficial owner of the Series A Convertible Preferred Stock



 ̈is a Foreigner



 ̈is not a Foreigner.



A Foreigner is (i) any person (including an individual, a partnership, a corporation, or an association) that is not a United States citizen or is the representative of or fiduciary for any person that is not a United
States citizen; (ii) any foreign government or the representative thereof; (iii) any corporation, the president, chief executive officer or chairman of the Board of which is a Foreigner, or of which more than a minority of its Directors necessary to
constitute a quorum are Foreigners; (iv) any corporation organized under the laws of any foreign government; (v) any corporation of which a majority of its shares are owned beneficially or of record, or may be voted by, Foreigners, or which by any
other means whatsoever is controlled by or in which control is permitted to be exercised by Foreigners; (vi) any partnership or association that is controlled by Foreigners; (vii) any corporation of which a 25% or greater interest is owned
beneficially or of record by Foreigners and which may be deemed to control the corporation (the Board being authorized to determine reasonably the meaning of control for this purpose); (viii) any other person deemed by the
Board to be a Foreigner as to the United States or the Company (or any Subsidiary) or otherwise not possessing prescribed qualifications to be a holder of outstanding shares of the Company in accordance with the policy set forth in the
Companys Amended Articles; or (ix) any person who acts as representative of or fiduciary for any person described in clauses (i) through (viii) above.



In the event of any changes in laws, including any amendment of maritime laws defining United States citizenship, the Board is specifically authorized to
take all actions as it deems appropriate and as are in accordance with the law and the Amended Articles including, but not limited to, making changes in the definitions of Permitted Percentage and Foreigner.
