Luxembourg -- (MARKET WIRE) -- January 30, 2006 --

                                 Press release

                 Arcelor board of Directors unanimously rejects
                           Mittal's hostile proposal

Luxembourg, 29 January, 2006 - At an extraordinary meeting in Luxembourg today, Arcelor's Board of Directors, under the chairmanship of Joseph Kinsch, has examined Mittal Steel's unsolicited proposal.

After a thorough review and analysis of the elements at its disposal, the Board has swiftly concluded that Arcelor and Mittal Steel do not share the same strategic vision, business model and values.

The Board then expressed its concern regarding the severe consequences that Mittal Steel's proposal could have on the group, its shareholders, employees and customers.

Furthermore, the Board of Directors believes that the continuation of Arcelor's present strategy offers the best guarantee of value creation for its shareholders.

Therefore, the Board of Directors has resolved that it:

1.   unanimously rejects Mittal Steel's unsolicited proposal which 
     it considers hostile,

2.   recommends to Arcelor's shareholders not to tender their shares
     into the proposed offer, if and when submitted,

3.   mandates the Management Board to present to the Board of 
     Directors all actions and options that are in the best interests
     of all stakeholders.

The Board of Directors confirms its full confidence in the management and employees of Arcelor and supports their ongoing efforts to create value for all stakeholders.

All these arguments will be presented in further detail at the news conference that will be held by Arcelor's group management board.
