COMPASS MINERALS GROUP, INC. MAKES $30 MILLION VOLUNTARY BANK DEBT REPAYMENT IN MARCH 2003

OVERLAND PARK, KS, March 28, 2003 - Compass Minerals Group, Inc., a leading producer and marketer of salt and specialty potash, today announced that it has made an additional $30 million voluntary bank debt repayment in March.

"We are seeing the full benefits from our prior year cost reduction initiatives and are continuing to apply the capital spending discipline practiced during 2002. In addition, winter demand for 2003 has been good in our combined deicing market areas," said Michael E. Ducey, President and CEO. "Therefore, we decided to apply our free cash flow resulting from these spending controls and solid sales results toward additional debt reduction. This reflects our confidence in the continued success of Compass Minerals Group and provides a very good first step in helping us meet our 2003 deleveraging goals."

Compass Minerals Group is the second largest North American producer of salt, the largest producer of salt in the United Kingdom and the largest North American producer of sulfate of potash, a specialty fertilizer. Compass Minerals Group is approximately 81% owned by Apollo Management L.P. and Company management, with the remainder owned by IMC Global Inc.
