EXHIBIT 99.3 April 29, 2003 Mr. John Lauer, Chairman Oglebay Norton Company 1001 Lakeside Avenue, 15th Floor Cleveland, Ohio 44114 Dear John, As you and I discussed, due to my recent illness, I am concerned about my ability to adequately serve as a director of Oglebay Norton Company at this time. Therefore, I hereby withdraw my name from nomination as a director; however, I am committed to serving in the future and would like the board to consider me as a candidate to serve after I have regained my health. Thank you for your understanding in this matter and I look forward to serving in the future. Sincerely, /s/ Judith A. Wolfe - ------------------- Judith A. Wolfe
