April 2, 2007 — Cleveland-Cliffs Inc. announced that its 3.25% redeemable cumulative convertible perpetual preferred stock may be surrendered for conversion at any time during the fiscal quarter ending June 30, 2007.

Convertibility of the preferred stock was made possible by the satisfaction of a condition to the conversion right of the holders of the 3.25% redeemable cumulative convertible perpetual preferred stock.

The condition was satisfied because the closing share price of Cleveland-Cliffs' common shares exceeded 110% of the then-applicable conversion price of the preferred stock for at least 20 of the last 30 trading days of the fiscal quarter ending March 31, 2007.

Satisfaction of this condition allows conversion of the preferred stock during the fiscal quarter ending June 30, 2007, only. Conversion may continue after such quarter if certain conditions set forth in Cleveland-Cliffs' amended articles of incorporation are satisfied.

The preferred stock was also convertible during each of the past nine fiscal quarters due to the satisfaction of this condition during the applicable periods.

The conversion rate is currently 65.5068 common shares per share of preferred stock, which equates to a conversion price of approximately $15.27 per common share, subject to adjustment in certain circumstances including payment of dividends on the common shares.
